Abstract
Importance Long-acting injectable (LAI) antipsychotics have the potential to improve adherence and symptom control in patients with schizophrenia, promoting long-term recovery. Paliperidone palmitate (PP) once every 6 months is the first and currently only LAI antipsychotic with an extended dosing interval of 6 months. Objective To assess long-term outcomes of PP received once every 6 months in adults with schizophrenia. Design, Setting, and Participants In a 2-year open-label extension (OLE) study of a 1-year randomized clinical trial (RCT), eligible adults with schizophrenia could choose to continue PP every 6 months if they had not experienced relapse after receiving PP once every 3 or 6 months in the 1-year, international, multicenter, double-blind, randomized noninferiority trial. The present analysis focused on patients receiving PP every 6 months in the double-blind trial through the OLE study (November 20, 2017, to May 3, 2022). Intervention Patients received a dorsogluteal injection of PP on day 1 and once every 6 months up to month 30. Main Outcomes and Measures End points included assessment of relapse and change from the double-blind trial baseline to the OLE end point in Positive and Negative Syndrome Scale (PANSS) total and subscale, Clinical Global Impression-Severity (CGI-S) Scale, and Personal Social Performance (PSP) Scale scores. Treatment-emergent adverse events (TEAEs), injection site evaluations, and laboratory tests were also assessed. Results Among 121 patients (83 [68.6%] male), mean (SD) age at baseline was 38.6 (11.24) years and mean (SD) duration of illness was 11.0 (9.45) years. At screening of the double-blind study, 101 patients (83.5%) were taking an oral antipsychotic and 20 (16.5%) were taking an LAI antipsychotic. Altogether, 5 of 121 patients (4.1%) experienced relapse during the 3-year follow-up; reasons for relapse were psychiatric hospitalization (2 [1.7%]), suicidal or homicidal ideation (2 [1.7%]), and deliberate self-injury (1 [0.8%]). Patients treated with PP every 6 months were clinically and functionally stable, and outcomes were well maintained, evidenced by stable scores on the PANSS (mean [SD] change, -2.6 [9.96] points), CGI-S (mean [SD] change, -0.2 [0.57] points), and PSP (mean [SD] change, 3.1 [9.14] points) scales over the 3-year period. In total, 101 patients (83.5%) completed the 2-year OLE. At least 1 TEAE was reported in 97 of 121 patients (80.2%) overall; no new safety or tolerability concerns were identified. Conclusions and Relevance In a 2-year OLE study of a 1-year RCT, results supported favorable long-term outcomes of PP once every 6 months for up to 3 years in adults with schizophrenia.

Extrapyramidal adverse events and anticholinergics use after the long-term treatment of patients with schizophrenia with the new long-acting antipsychotic Risperidone ISM ®: results from matching-adjusted indirect comparisons versus once-monthly formulations of Paliperidone palmitate and Aripiprazole monohydrate in 52-week studies. Ann Gen Psychiatry 2023; 22:33. [PMID: 37660132 PMCID: PMC10474682 DOI: 10.1186/s12991-023-00464-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/23/2023] [Accepted: 08/22/2023] [Indexed: 09/04/2023] Open
Abstract
BACKGROUND Risperidone ISM® is a newly developed long-acting injectable (LAI) treatment for schizophrenia in adults. In the absence of head-to-head comparisons with other similar antipsychotics, the objective of this study was to generate indirect evidence of some aspects of the safety and tolerability of Risperidone ISM compared to other LAI antipsychotics for treatment of patients with schizophrenia in the maintenance treatment setting. METHODS A literature review was conducted systematically to identify maintenance treatment studies reporting safety and tolerability outcomes for LAI antipsychotic therapies. Following an assessment of between-trial heterogeneity, a matching-adjusted indirect comparison (MAIC) was performed to account for between-trial imbalances in patient characteristics and to generate comparative evidence for safety and tolerability endpoints. RESULTS The analysis showed that incidence of extrapyramidal symptoms (EPS) was found to be numerically, but not statistically significantly, lower in patients receiving Risperidone ISM than in those receiving Paliperidone palmitate (PP) (OR [95% CI] 0.63 [0.29, 1.38], p = 0.253) and statistically significantly lower than with Aripiprazole monohydrate once-monthly (AOM) (OR [95% CI] 0.25 [0.12, 0.53], p < 0.001). Use of anticholinergic agents for the alleviation of EPS was also shown to be significantly lower in Risperidone ISM patients than in those receiving PP (OR [95% CI] 0.29 [0.10, 0.83], p = 0.021) or AOM (OR [95% CI] 0.01 [0.003, 0.06], p < 0.001), suggesting a superior tolerability profile for clinically relevant EPS. Results from the sensitivity analyses comparing stabilized and stable patients receiving Risperidone ISM to those receiving AOM yielded similarly favorable conclusions in line with the base case analyses. CONCLUSIONS This MAIC is consistent with the safety and tolerability results obtained during the PRISMA-3 clinical trial in the long-term treatment of schizophrenia and suggests a favorable safety and tolerability profile in terms of EPS incidence and anticholinergic agent use, relative to other antipsychotic therapies used for treatment of patients with schizophrenia in the maintenance setting.

Abstract
BACKGROUND Paliperidone palmitate 6-month (PP6M) demonstrated noninferiority to paliperidone palmitate 3-month in preventing relapse in patients with schizophrenia in a phase 3 double-blind (DB) study (NCT03345342). Here, we report long-term efficacy and safety results from a 2-year single-arm, open-label extension (OLE; NCT04072575) of this DB study. METHODS Participants who completed the DB study without relapse were enrolled and followed-up every 3 months up to 2 years. Participants received 4 PP6M gluteal injections (700/1000 mg eq.) at baseline, 6-month, 12-month, and 18-month visits. Efficacy endpoints included assessment of relapse, Positive and Negative Syndrome Scale total score, Personal and Social Performance score, and Clinical Global Impression-Severity scale change from baseline. Safety was assessed by treatment-emergent adverse events (TEAEs), physical examinations, and laboratory tests. RESULTS Of 178 participants enrolled, 154 (86.5%) completed the OLE (mean age: 40.4 years, men: 70.8%; mean duration of PP6M exposure during OLE: 682.1 days). Overall, 7/178 (3.9%) participants relapsed between 20 and 703 days after enrolment. Mean (SD) changes from baseline to endpoint were as follows: Positive and Negative Syndrome Scale total score, 0.7 (8.22); Clinical Global Impression-Severity, 0.0 (0.51); and Personal and Social Performance Scale, 0.5 (7.47). Overall, 111/178 participants (62.4%) reported ≥1 TEAE; most common (>5%) TEAEs were headache (13.5%) and increased blood prolactin/hyperprolactinemia (18.0%); 8/178 (4.5%) participants experienced serious TEAEs, and 6/178 (3.4%) participants withdrew due to TEAEs. No deaths were reported. CONCLUSIONS The relapse rate observed with PP6M during the 2-year OLE was low (3.9%). Clinical and functional improvements demonstrated in the DB study were maintained during OLE, and no new safety concerns were identified. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT04072575; EudraCT number: 2018-004532-30.

The Effect of Longer Dosing Intervals for Long-Acting Injectable Antipsychotics on Outcomes in Schizophrenia. Neuropsychiatr Dis Treat 2023; 19:531-545. [PMID: 36915909 PMCID: PMC10008005 DOI: 10.2147/ndt.s395383] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 01/12/2023] [Indexed: 03/16/2023] Open
Abstract
Medication nonadherence in schizophrenia can have serious implications including relapses and hospitalization. Long-acting injectable (LAI) antipsychotics require fewer administrations, while ensuring sustained medication coverage. In this review, we summarize the expected real-world benefits of longer dosing intervals in the management of schizophrenia. LAIs are associated with improved clinical outcomes of less frequent relapses and reduced functional impairment, encouraging patients to regain control of their lives. Aripiprazole lauroxil and paliperidone palmitate three-monthly (PP3M) LAIs have longer dosing intervals of 2-3 months and provide improved outcomes in patients with schizophrenia. Paliperidone palmitate six-monthly (PP6M) LAI provides the longest dosing interval, twice-yearly dosing, among existing LAIs. Decreasing the frequency of LAI administrations has the potential to reduce occurrence of serious outcomes associated with poor medication adherence. By eliminating the need for daily oral antipsychotic dosing, LAIs could increase the likelihood of patient acceptance, decrease stigma, and promote self-esteem. Longer intervals of medication coverage may be desirable for patients with higher risk of relapse including adults with recent-onset schizophrenia, those living in circumstances that may deprive them of regular access (eg, homeless), those that are in transitions between care settings or to reduce interpersonal contact during public health emergencies (eg, COVID-19 pandemic).

Abstract
OBJECTIVES To compare mental healthcare use and healthcare professional (HCP) contacts for patients before and after initiation of paliperidone palmitate. SETTING The South London and Maudsley NHS Foundation Trust (SLAM) Biomedical Research Centre Clinical Record Interactive Search. PARTICIPANTS We identified all adults with a diagnosis of schizophrenia (International Classification of Diseases 10th Revision: F20.x), who had received paliperidone palmitate prescription for at least 365 days and had at least 1 year of recorded treatment from SLAM, prior to the first recorded receipt of paliperidone palmitate. PRIMARY AND SECONDARY OUTCOME MEASURES Inpatient and community mental healthcare service use, such as inpatient bed days, number of active days in the service, face-to-face and telephone HCP use in the 12 months before and after paliperidone palmitate initiation. RESULTS We identified 664 patients initiated on paliperidone palmitate. Following initiation, inpatient bed days were lower, although patients remained active on the service case load longer for both mirror approach 1 (mean difference of inpatient bed days -10.48 (95% CI -15.75 to -5.22); days active 40.67 (95% CI 33.39 to 47.95)) and mirror approach 2 (mean difference of inpatient bed days -23.96 (95% CI -30.01 to -17.92); mean difference of days active 40.69 (95% CI 33.39 to 47.94)). The postinitiation period was further characterised by fewer face-to-face and telephone contacts with medical and social work HCPs, and an increased contact with clinical psychologists. CONCLUSIONS Our findings indicate a change in the profile of HCP use, consistent with a transition from treatment to possible rehabilitation.

Long-term efficacy and safety of once-monthly Risperidone ISM® in the treatment of schizophrenia: Results from a 12-month open-label extension study. Schizophr Res 2022; 239:83-91. [PMID: 34847501 DOI: 10.1016/j.schres.2021.11.030] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 10/04/2021] [Accepted: 11/17/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVE To evaluate long-term efficacy, safety and tolerability of Risperidone ISM® in patients with schizophrenia, a multicenter, open-label extension of the PRISMA-3 study was conducted. METHODS Eligible placebo (unstable) and Risperidone ISM® (stabilized) rollover patients from a previous 12-week double-blind phase and de novo stable patients received once-monthly intramuscular injections of Risperidone ISM® 75 or 100 mg for 12 months. The long term-efficacy assessment included the Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Severity (CGI-S) and Clinical Global Impression-Improvement (CGI-I) scales. Safety evaluation included treatment-emergent adverse events (TEAEs), injection site reactions (ISR), laboratory tests and several safety scales. RESULTS Altogether, 215 patients entered the study (55 unstable, 119 stabilized and 41 stable patients). Most patients (74.9%) completed, and discontinuation rates were broadly similar across the study subgroups, mainly due to withdrawal of consent (12.1%). PANSS total and subscales scores decreased from baseline to endpoint in all groups, with the largest decrease for unstable patients. Improvement from baseline to 12 months was also shown for CGI-S and CGI-I scores for both unstable and stabilized patients; the CGI-S and CGI-I scores remained almost unchanged for the stable group. At least one treatment-related TEAE was reported in 39.1% of patients; the most common were headache (12.1%), hyperprolactinemia (9.8%) and asthenia (5.1%). ISR were reported in 8 (0.3%) patients; injection site pain score was low across the 2355 doses assessed. CONCLUSION Risperidone ISM® is an effective, safe, and well-tolerated long-term treatment of schizophrenia in adults, regardless of the initial disease severity or whether patients were previously treated with Risperidone ISM® during an acute exacerbation or switched from stable doses of oral risperidone.

Abstract
PURPOSE/BACKGROUND The aim of the study was a preliminary evaluation of the maintenance of clinical efficacy and tolerability of paliperidone palmitate in patients with schizophrenia during the transition phase from 1-monthly paliperidone palmitate formulation (PP1M) to PP3M, with the evaluation of plasma levels of the drug. METHODS/PROCEDURES A prospective observational study was conducted for 13 months involving 22 outpatients, aged 18 to 66 years and clinically stabilized. Patients were affected by schizophrenia according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria. For each patient, clinical assessment, safety and tolerability, and drug plasma level determination were performed. Clinical efficacy was assessed by Brief Psychiatric Rating Scale, Positive and Negative Symptom Scale, and Hamilton Rating Scale for Depression. During the first 4 months of the study, once-monthly paliperidone palmitate was administered, and then during the following 9 months, the 3-monthly formulation was administered. FINDINGS/RESULTS The time course of the Brief Psychiatric Rating Scale total scores showed a statistically significant (P = 0.006) improvement from T0 to T8; Positive and Negative Symptom Scale scores showed a similar time course, with a statistically significant (P = 0.0016) reduction of the mean total score; Hamilton Rating Scale for Depression mean scores showed a statistically significant (P = 0.003) reduction with substantial maintenance of clinical stabilization of the patients. Only 1 patient dropped out after the first PP3M injection. IMPLICATIONS/CONCLUSIONS Our preliminary data currently confirm the maintenance of clinical stability shifting from PP1M to PP3M.

Abstract
BACKGROUND This double-blind (DB), randomized, parallel-group study was designed to evaluate efficacy and safety of paliperidone palmitate 6-month (PP6M) formulation relative to paliperidone palmitate 3-month (PP3M) formulation in patients with schizophrenia. METHODS Following screening, patients entered an open-label (OL) maintenance phase and received 1 injection cycle of paliperidone palmitate 1-month (PP1M; 100 or 150 mg eq.) or PP3M (350 or 525 mg eq.). Clinically stable patients were randomized (2:1) to receive PP6M (700 or 1000 mg eq., gluteal injections) or PP3M (350 or 525 mg eq.) in a 12-month DB phase; 2 doses of PP6M (corresponding to doses of PP1M and PP3M) were chosen. RESULTS Overall, 1036 patients were screened, 838 entered the OL phase, and 702 (mean age: 40.8 years) were randomized (PP6M: 478; PP3M: 224); 618 (88.0%) patients completed the DB phase (PP6M: 416 [87.0%]; PP3M: 202 [90.2%]). Relapse rates were PP6M, 7.5% (n = 36) and PP3M, 4.9% (n = 11). The Kaplan-Meier estimate of the difference (95% CI) between treatment groups (PP6M - PP3M) in the percentages of patients who remained relapse free was -2.9% (-6.8%, 1.1%), thus meeting noninferiority criteria (95% CI lower bound is larger than the pre-specified noninferiority margin of -10%). Secondary efficacy endpoints corroborated the primary analysis. Incidences of treatment-emergent adverse events were similar between PP6M (62.1%) and PP3M (58.5%). No new safety concerns emerged. CONCLUSIONS The efficacy of a twice-yearly dosing regimen of PP6M was noninferior to that of PP3M in preventing relapse in patients with schizophrenia adequately treated with PP1M or PP3M.

Abstract
Introduction At 11:20 on 26 May 2018, a physician from Lianyungang No. 1 People's Hospital, China, reported that six family members were being treated in the hospital with symptoms from an unknown cause. Methods A case series for a food poisoning investigation and an environmental survey were conducted. The patients and their relatives were interviewed in person with a questionnaire contained on a digital tablet, and an investigation of the patients' home was conducted in the presence of police officers. Probable case and confirmed case were defined to serve as a basis for identifying additional cases. Confirmed cases were defined as those probable cases in which blood, stool or vomitus specimens tested positive for paliperidone palmitate and/or its metabolites. A descriptive analysis was performed. Follow-up by telephone was conducted four months later. Results There were six probable cases. The median age was 35 years (range: 5-76 years). The attack rate was 100% (n = 6/6) of persons who consumed a family dinner, and the hospitalization rate was also 100% (n = 6/6). The median period between exposure and symptom onset was two hours. The main symptoms included vomiting, nausea, drowsiness, dizziness and severe abdominal pain for adults, and vomiting and severe lethargy for children. An 8-year-old girl further showed changes in the ST segment of her electrocardiogram, and a 5-year-old boy showed QT prolongation. The poisoning substance was suspected to be paliperidone palmitate based on the patients' symptoms and epidemiological findings. Discussion We investigated the household food poisoning outbreak through epidemiological analysis and an environmental investigation and determined that it was caused by paliperidone palmitate. The source of the paliperidone palmitate was found to be aluminium containers, taken home by the eldest son who worked at a pharmaceutical company. The containers were sent to a drug disposal centre, and the pharmaceutical company was required to enhance the regulation on the pharmaceutical waste materials to prevent drug poisoning events. By the end of September 2018, the six patients recovered and were released from the hospital, and they did not show any clinical sequelae in four follow-up visits.

Abstract
BACKGROUND The symptoms and signs of schizophrenia have been linked to high levels of dopamine in specific areas of the brain (limbic system). Antipsychotic drugs block the transmission of dopamine in the brain and reduce the acute symptoms of the disorder. An original version of the current review, published in 2012, examined whether antipsychotic drugs are also effective for relapse prevention. This is the updated version of the aforesaid review. OBJECTIVES To review the effects of maintaining antipsychotic drugs for people with schizophrenia compared to withdrawing these agents. SEARCH METHODS We searched the Cochrane Schizophrenia Group's Study-Based Register of Trials including the registries of clinical trials (12 November 2008, 10 October 2017, 3 July 2018, 11 September 2019). SELECTION CRITERIA We included all randomised trials comparing maintenance treatment with antipsychotic drugs and placebo for people with schizophrenia or schizophrenia-like psychoses. DATA COLLECTION AND ANALYSIS We extracted data independently. For dichotomous data we calculated risk ratios (RR) and their 95% confidence intervals (CIs) on an intention-to-treat basis based on a random-effects model. For continuous data, we calculated mean differences (MD) or standardised mean differences (SMD), again based on a random-effects model. MAIN RESULTS The review currently includes 75 randomised controlled trials (RCTs) involving 9145 participants comparing antipsychotic medication with placebo. The trials were published from 1959 to 2017 and their size ranged between 14 and 420 participants. In many studies the methods of randomisation, allocation and blinding were poorly reported. However, restricting the analysis to studies at low risk of bias gave similar results. Although this and other potential sources of bias limited the overall quality, the efficacy of antipsychotic drugs for maintenance treatment in schizophrenia was clear. Antipsychotic drugs were more effective than placebo in preventing relapse at seven to 12 months (primary outcome; drug 24% versus placebo 61%, 30 RCTs, n = 4249, RR 0.38, 95% CI 0.32 to 0.45, number needed to treat for an additional beneficial outcome (NNTB) 3, 95% CI 2 to 3; high-certainty evidence). Hospitalisation was also reduced, however, the baseline risk was lower (drug 7% versus placebo 18%, 21 RCTs, n = 3558, RR 0.43, 95% CI 0.32 to 0.57, NNTB 8, 95% CI 6 to 14; high-certainty evidence). More participants in the placebo group than in the antipsychotic drug group left the studies early due to any reason (at seven to 12 months: drug 36% versus placebo 62%, 24 RCTs, n = 3951, RR 0.56, 95% CI 0.48 to 0.65, NNTB 4, 95% CI 3 to 5; high-certainty evidence) and due to inefficacy of treatment (at seven to 12 months: drug 18% versus placebo 46%, 24 RCTs, n = 3951, RR 0.37, 95% CI 0.31 to 0.44, NNTB 3, 95% CI 3 to 4). Quality of life might be better in drug-treated participants (7 RCTs, n = 1573 SMD -0.32, 95% CI to -0.57 to -0.07; low-certainty evidence); probably the same for social functioning (15 RCTs, n = 3588, SMD -0.43, 95% CI -0.53 to -0.34; moderate-certainty evidence). Underpowered data revealed no evidence of a difference between groups for the outcome 'Death due to suicide' (drug 0.04% versus placebo 0.1%, 19 RCTs, n = 4634, RR 0.60, 95% CI 0.12 to 2.97,low-certainty evidence) and for the number of participants in employment (at 9 to 15 months, drug 39% versus placebo 34%, 3 RCTs, n = 593, RR 1.08, 95% CI 0.82 to 1.41, low certainty evidence). Antipsychotic drugs (as a group and irrespective of duration) were associated with more participants experiencing movement disorders (e.g. at least one movement disorder: drug 14% versus placebo 8%, 29 RCTs, n = 5276, RR 1.52, 95% CI 1.25 to 1.85, number needed to treat for an additional harmful outcome (NNTH) 20, 95% CI 14 to 50), sedation (drug 8% versus placebo 5%, 18 RCTs, n = 4078, RR 1.52, 95% CI 1.24 to 1.86, NNTH 50, 95% CI not significant), and weight gain (drug 9% versus placebo 6%, 19 RCTs, n = 4767, RR 1.69, 95% CI 1.21 to 2.35, NNTH 25, 95% CI 20 to 50). AUTHORS' CONCLUSIONS For people with schizophrenia, the evidence suggests that maintenance on antipsychotic drugs prevents relapse to a much greater extent than placebo for approximately up to two years of follow-up. This effect must be weighed against the adverse effects of antipsychotic drugs. Future studies should better clarify the long-term morbidity and mortality associated with these drugs.

Abstract
Objective: To analyze the efficacy and safety of paliperidone palmitate 3-monthly (PP3M) in Latin American patients with schizophrenia vs. rest-of-world (ROW). Methods: We analyzed data from two multinational, double-blind (DB), randomized, controlled phase 3 studies including patients with schizophrenia (DSM-IV-TR) previously stabilized on PP1M/PP3M (open-label [OL] phase). Patients were randomized to PP3M or PP1M (noninferiority study A) and PP3M or placebo (study B) in DB phase. The subgroup analysis included Latin American (Argentina, Brazil, Colombia, Mexico) patients. Primary efficacy endpoints were relapse-free rates (study A) and time-to-relapse (study B). Results: In study A, 63/71 (88.7%) and in study B 38/43 (88.4%) Latin American patients completed the DB phase. In study A, relapse-free percentage was similar in Latin America (PP3M: 97%, PP1M: 100%) and ROW (PP3M: 91%, PP1M: 89%). In study B, median time-to-relapse was not estimable in the Latin American subgroup for either placebo or PP3M groups, nor for the ROW PP3M group; the median time-to-relapse in the ROW placebo group was 395 days. Caregiver burden improved in patients switching from oral antipsychotics (OL baseline) to PP3M/PP1M in DB phase (Involvement Evaluation Questionnaire score mean ± SD change, -9.4±15.16; p < 0.001). Treatment emergent adverse events with PP3M during DB phase were similar in Latin America (study A: 24/34 [70.6%]; study B: 15/21 [71.4%]) and ROW (study A: 318/470 [67.7%]; study B: 84/139 [60.4%]) subgroups. Conclusion: PP3M was efficacious and showed no new safety concerns in patients with schizophrenia from Latin America, corroborating ROW findings. Clinical trial registration: NCT01515423, NCT01529515

Abstract
Background Antipsychotics are an effective treatment option for patients with schizophrenia and several long-acting injectables (LAIs), including risperidone, olanzapine, paliperidone, and aripiprazole are available in the UK. Treatment adherence is an issue in severe mental illness and LAIs have been hypothesized to offer clinical advantages over their oral equivalents. However, meta-analyses of randomized clinical trials and mirror-image studies have yielded equivocal results and have focused on economic rather than clinical outcomes. Objective This study evaluated routinely collected data to ascertain cost-effectiveness and clinical outcomes of two LAIs, aripiprazole and paliperidone palmitate once a month. Clinical effectiveness was assessed using the Health of the Nation Outcome Scale (HoNOS) scores. Materials and methods A 1-year mirror image observational study of patients cared for by North Staffordshire Combined Healthcare Trust who received either the LAIs aripiprazole or paliperidone once a month from 2011 until the end of the study in 2016. The primary outcome was the effectiveness of the LAIs using a mirror-image design with HoNOS scores and bed use as the main outcomes. Results A total of 30 patients received aripiprazole and 84 received paliperidone once a month during the study period. A significant reduction in bed use was accompanied by clinical improvements, as measured by the HoNOS for both study drugs (aripiprazole: 13.4 before vs 8.7 after [P=0.001]; paliperidone: 15.8 before vs 12.9 after [P=0.02]). Analysis of several metabolic markers showed mean values within the normal range but the mean prolactin level in patients treated with paliperidone once a month was elevated. Conclusion The LAIs aripiprazole and paliperidone once a month are associated with clinical improvement and reduced bed use. Routine data gathering using, for example, HoNOS will offer the opportunity to provide additional insights into the clinical and cost benefits associated with LAIs and other interventions in the treatment of schizophrenia.

Abstract
PURPOSE/BACKGROUND This article evaluates gender bias in the published clinical trials of new long-acting antipsychotics. METHODS/PROCEDURES We conducted a review of controlled clinical trials of the new prolonged-release antipsychotics (aripiprazole, risperidone, or paliperidone) for the treatment of schizophrenia published in MEDLINE over the last 10 years and available in full text in English. The study followed the corresponding international recommendations. RESULTS We identified 132 trials, and of these, 40 met the inclusion and exclusion criteria. We found that only 36.41% of the total patients were women. The separate analysis of the main variable between the subpopulations of men and women was carried out in only 6 of the 40 works included. In contrast, in 15 trials, this analysis was performed on secondary variables, generally related to safety. Only 3 of the 40 trials discussed the results separately according to sex. CONCLUSIONS The clinical trials of long-acting atypical antipsychotic drugs show a far-from-negligible gender bias. Women are underrepresented, and the main and secondary variables are not analyzed separately according to gender. This is despite international recommendations establishing these criteria as part of a package of minimum requirements for meeting scientific validity and making results apt to extrapolate to the general population of patients.

Abstract
Background: In this post hoc analysis in patients recently diagnosed (≤5 years) with schizophrenia, the effect on hospitalization risk after switching from oral antipsychotic to once-monthly paliperidone palmitate (PP1M) was evaluated. Research design and methods: Change in hospitalization risk following PP1M initiation among patients switching from oral antipsychotics was assessed using prescription sequence symmetry analysis. Hospitalization risk was expressed as an adjusted sequence ratio (ASR) of the number of patients hospitalized prior to PP1M initiation/post PP1M initiation. Cumulative distribution of the time to hospitalization was estimated by the Kaplan-Meier method and symmetry of distribution was assessed using log-rank test. Hazard ratio and 95% CI were calculated using the Cox proportional hazard model. Results: The number of patients hospitalized after switching to PP1M: no change, 203/300 (67.7%); increase, 18/300 (6.0%); and decrease, 79/300 (26.3%). Following PP1M initiation, ASR (95% CI) was 3.56 (2.67, 5.33) suggesting asymmetry and a significant decline in hospitalization risk. Asymmetry in distribution of hospitalization events with significant (p ≤ 0.001) delay in time to hospitalization was also observed. Conclusion: Switching to PP1M treatment from oral antipsychotics is likely to be associated with a significant reduction in hospitalization risk along with a delay in time to hospitalization and rehospitalization.

Neuropsychiatr Dis Treat 2019; 15:1365-1379. [PMID: 31190840 PMCID: PMC6535080 DOI: 10.2147/ndt.s197225] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2018] [Accepted: 04/02/2019] [Indexed: 12/11/2022] Open
Abstract
Antipsychotics are the mainstay in schizophrenia management, and long-acting injectable (LAI) antipsychotics contribute to the successful maintenance of treatment by improving non-adherence and preventing relapses. Paliperidone palmitate 3-monthly (PP3M) formulation is the only available LAI antipsychotic that offers an extended 3-month window of stable plasma drug concentration, enabling only four injections per year. This paper summarizes clinically relevant endpoints from available evidence for PP3M to bridge translational research gaps and provide measurable outcomes that can be interpreted in clinical practice. Low number-needed-to-treat (NNT) for relapse prevention (NNT [95% CI] 6-month estimate: 4.8 [3.2; 10.0]; 12-month estimate: 3.4 [2.2; 7.0]), and high number-needed-to-harm (NNH [95% CI] akathisia, 27.1 [12.3; -667.1]; tremor, 80.0 [22.5; 67.3]; dyskinesia, -132.6 [44.5; -23.2]; parkinsonism, 160.0 [28.9; -49.8]) quantify the relative benefits and low propensity for adverse events with PP3M. Symptom remission and reductions in positive and negative symptoms indicate treatment stability. Additionally, meaningful functional remission, reduced dosing frequency, and freedom from daily negotiations favorably impact patient preference and attenuate burdensome aspects of caregiving, representing important healthcare determinants that enhance prospects of treatment continuity in schizophrenia. This information can potentially improve clinicians' judgment of treatment choices, clinical response, and patient selection in routine care. Taken together, PP3M is a valuable antipsychotic treatment option, meriting consideration for a broader role in the long-term management of schizophrenia; its utility should not be limited to patients with poor adherence or when oral antipsychotics have failed.

Abstract
AIM The aim of this review was to analyze the discontinuation rates during long-term treatment with second-generation antipsychotic long-acting injection (SGA-LAI) in adults with either schizophrenia spectrum or bipolar disorders. METHODS A systematic search (PubMed, Scopus, and the Cochrane Library) of studies published in English (1 January 2001-12 October 2018) identified 1214 abstracts, which were analyzed independently by the author and two colleagues. Studies were retrieved and reviewed if they reported primary data on the discontinuation rate before the study end during treatment lasting ≥36 weeks. Data were extracted from 51 articles meeting the inclusion criteria. RESULTS In all head-to-head comparisons, and studies on patients with schizophrenia spectrum or bipolar disorders, the discontinuation rate before the study end in patients treated with SGA-LAI was, at best, similar to that recorded in patients treated with first-generation antipsychotics in either oral or LAI formulations or with oral SGA. In particular, in most of the SGA-LAI long-term studies, the rate of premature dropout was higher than 50%. CONCLUSION Reviewed data suggest that SGA-LAI show no clear superiority over less expensive drugs (including first-generation antipsychotic LAI and oral antipsychotic formulations) in reducing the risk of premature antipsychotic discontinuation. Thus, alternative strategies should be considered to improve medication persistence and lower discontinuation rates in patients with severe psychiatric disorders. Planning tailored, individualized, and integrated approaches (including frequent clinical evaluations, and behavioral or other flexible techniques adaptable to different settings and patients) may be an effective intervention for improving patient adherence in long-term pharmacological treatment regimens.

Abstract
PURPOSE This randomized, double-blind (DB), non-inferiority phase 3 study was conducted to assess the efficacy and safety of paliperidone palmitate 3-month (PP3M) vs 1-month formulation (PP1M) in European and non-European patients with schizophrenia. PATIENTS AND METHODS In this randomized, DB, parallel-group study, adult patients (18-70 years) with schizophrenia (per DSM-IV-TR) having Positive and Negative Syndrome Scale (PANSS) total score between 70 and 120; previously stabilized on PP1M were enrolled. The study had 4 phases: screening (3 weeks), open-label (OL) stabilization (17 weeks), DB (48 weeks) and follow-up (4-12 weeks) phase. Patients were treated with fixed-dose PP3M (175-525 mg eq deltoid/gluteal) or PP1M (50-150 mg eq deltoid/gluteal) for 48 weeks in DB phase. RESULTS In total, 487 European (PP3M, n=242; PP1M, n=245) and 508 non-European patients (PP3M, n=241; PP1M, n=267) entered DB phase (modified intent-to-treat (mITT) [DB] analysis set). Among the 508 non-European patients in mITT set, 67.7% were from Asia (n=344) and 32.3% were from rest of world (ROW, n=164). During the DB phase, similar percentage of Europeans (PP3M: 7%; PP1M: 8%) and non-Europeans (PP3M: 9%; PP1M: 10%) experienced relapse (Kaplan-Meier estimate PP3M-PP1M [95% CI] of percentage of relapse-free patients at the end of DB phase [primary endpoint]: European: 1.0% [-4.3%; 6.2%]; non-European: 1.4% [-4.4%; 7.1%]; Asian: 1.6% [-5.7%; 9.0%]; and ROW: 1.4% [-7.0%, 9.8%], per-protocol analysis set). Incidence of treatment-emergent adverse events (TEAEs) was lower in Europeans (PP3M: 56%, PP1M: 59%) than non-Europeans (PP3M: 80%, PP1M: 73%). The most commonly reported TEAE was weight gain. CONCLUSION PP3M showed similar efficacy to PP1M in Europeans and non-Europeans, consistent with non-inferiority of PP3M to PP1M observed in overall population. Rates of AEs were higher in non-Europeans. However, weight gain was greater in non-Europeans, especially the Asian population.

Abstract
BACKGROUND The cause of the obesity epidemic is multifactorial, but may, in part, be related to medication-induced weight gain. While clinicians may strive to do their best to select pharmacotherapy(ies) that has the least negative impact on weight, the literature regarding the weight effects of medication is often limited and devoid of alternative therapies. RESULTS Antipsychotics, antidepressants, antihyperglycemics, antihypertensives and corticosteroids all contain medications that were associated with significant weight gain. However, there are several medication alternatives within the majority of these classes associated with weight neutral or even weight loss effects. Further, while not all of the classes of medication examined in this review have weight-favorable alternatives, there exist many other tools to mitigate weight gain associated with medication use, such as changes in dosing, medication delivery or the use of adjunctive therapies. CONCLUSION Medication-induced weight gain can be frustrating for both the patient and the clinician. As the use of pharmaceuticals continues to increase, it is pertinent for clinicians to consider the weight effects of medications prior to prescribing or in the course of treatment. In the case where it is not feasible to make changes to medication, adjunctive therapies should be considered.

Abstract
BACKGROUND Limited data are available to help identify patients with schizophrenia who are most likely to benefit from long-acting injectable antipsychotics. AIM To investigate the efficacy of long-acting injectable antipsychotic paliperidone palmitate one-month formulation for preventing relapses, factors influencing time to first relapse, and the effect of different antipsychotic adherence levels on time to first relapse in Chinese patients with schizophrenia. METHODS This was a post-hoc analysis from an open-label, single-arm study of stable patients (Positive and Negative Syndrome Scale total score <70; n=367) receiving paliperidone palmitate one-month formulation at the end of an acute 13-week treatment phase, who entered a naturalistic one-year follow-up period, either continuing with flexibly dosed paliperidone palmitate one-month formulation (75-150 mg eq.) or switching to another antipsychotic(s). RESULTS There were 362/367 patients (age=31.4±10.75 years) included in the analysis of time to first relapse (primary outcome) and 327/362 patients (39/327, poor antipsychotic adherence (<80%)) willing to receive antipsychotics were included in the exposure/adherence analysis. Overall, 84.6% (95% confidence interval=79.2-88.7) patients remained relapse-free. Poor adherence during follow-up (hazard ratio=2.97, 95% confidence interval=1.48-5.98, p=0.002) and frequent hospitalizations in the previous year (hazard ratio=1.29, 95% confidence interval=1.02-1.62, p=0.03) were associated with a significant risk of shorter time to first relapse in the univariate analysis. In patients with poor adherence, 'no use' (hazard ratio=13.13, 95% confidence interval=1.33-129.96, p=0.03) and 'interrupted use' (hazard ratio=11.04, 95% confidence interval=1.03-118.60, p=0.047) of paliperidone palmitate one-month formulation (vs continued use) showed a significantly higher risk of relapse; this was not observed in patients with good (≥80%) antipsychotic adherence. No new safety concerns were identified. CONCLUSION Continued use of paliperidone palmitate one-month formulation/long-acting injectable antipsychotic was effective in preventing schizophrenia relapses, especially in patients with suboptimal antipsychotic adherence.

Abstract
The course of schizophrenia is characterized by multiple relapses, incomplete remission of symptoms, enduring cognitive deficits, and social and occupational functional impairments. Nonadherence to antipsychotic medication is a major determinant of this poor outcome. Long-acting injectable antipsychotics were developed specifically to address the nonadherence problem and are increasingly considered as an early treatment option, in an attempt to prevent accruing morbidity. This review focuses on paliperidone palmitate, the long-acting injectable (LAI) formulation of paliperidone. After considering the pharmacology of paliperidone palmitate, we review the randomized controlled trials, as well as pertinent observational, pragmatic studies for paliperidone once-monthly injections in schizophrenia. Finally, we review the recently introduced 3-monthly formulation of paliperidone palmitate. Taken together, the studies indicate that paliperidone palmitate (PP) has good efficacy compared with placebo and comparable with other antipsychotics including risperidone. The tolerability profile of PP is similar to that of risperidone, with the most important side effects being prolactin elevation, weight gain, and extrapyramidal symptoms. Advantages of PP include the extensive research database and clinical experience with paliperidone and its parent compound risperidone, the availability of different LAI formulations (once-monthly, 3-monthly, and perhaps even longer acting formulations in future), and the novel dose initiation procedure that provides rapid onset of action without the need for oral antipsychotic supplementation.

Abstract
BACKGROUND Paliperidone palmitate once-monthly (PP1M) demonstrated symptomatic and functional remission in patients with schizophrenia. This post hoc analysis aimed to identify factors associated with improved clinical outcomes in patients switching to PP1M (75-150 mg eq.). METHODS The improved patient outcomes were observed as Positive and Negative Symptom Scale (PANSS, symptoms) score <70:66.7% (407/610), Personal and Social Performance (PSP, function) score >70:34.3% (199/581), and Involvement Evaluation Questionnaire (IEQ, caregiver burden) reduction ≥6:50.2% (270/538). Independent variables including demographics, disease duration, employment status, and clinical scores were screened individually using a univariate analysis and subsequently, variables (cutoff p<0.15) were analyzed using a multivariate regression analysis for association with better clinical outcomes at week 13. RESULTS The factors significantly associated with favorable clinical outcomes were reduction in PANSS at week 5 (odds ratio [OR]=1.14, 95% CI=1.11-1.17) with symptom reduction; baseline PSP total score (OR=1.07, 95% CI=1.05-1.10), PSP change at week 5 (OR=1.07, 95% CI=1.05-1.10), PANSS reduction at week 5 (OR=1.06, 95% CI=1.03-1.08) with functional improvement, reduction in PANSS at week 5 (OR=1.02, 95% CI=1.01-1.03), and total IEQ score at baseline (OR=1.09, 95% CI=1.07-1.11) with caregiver burden reduction. CONCLUSION Thus, symptom and functional improvements with caregiver burden reduction were observed in patients, and PANSS reduction at week 5 was commonly associated with favorable outcomes.

Abstract
OBJECTIVE The aim of this study was to evaluate the safety of 3-monthly paliperidone palmitate (PP3M) vs once-monthly paliperidone palmitate (PP1M) treatment with regard to extrapyramidal symptom (EPS)-related treatment-emergent adverse events (TEAEs) in patients with schizophrenia, previously stabilized on PP1M treatment. PATIENTS AND METHODS Data on overall incidence, time to onset (TTO), and time to resolution (TTR) of EPS-related TEAEs (overall, subclasses such as dyskinesia, dystonia, hyperkinesia, parkinsonism, and tremor) from a randomized double-blind (DB) non-inferiority study were compared between PP3M and PP1M. Subgroup analysis was performed by age (18-25, 26-50, and 50+ years) and final open-label (OL) dose (50/75, 100, and 150 mg eq.). RESULTS Overall incidence of spontaneously reported EPS-related TEAEs decreased from 12.6% (PP1M) in OL phase to 8.3% (PP3M) and 7.4% (PP1M) in the DB phase; overall median TTO and TTR values were comparable between both groups. Among patients with reported EPS-related TEAEs, the median TTO for all EPS-related TEAEs was 17 days (PP1M) in OL phase and 115 days (PP3M) and 98.5 days (PP1M) in DB phase; median TTR was 36.5 days (PP1M) in OL phase and 91 days (PP3M) and 85.5 days (PP1M) in DB phase. No clear dose- or age-related differences in TTO and TTR of EPS-related TEAEs were noted. CONCLUSION Despite differences in apparent half-life and pharmacokinetic profiles (peak plasma exposure of PP3M formulation is 70% higher than that of PP1M formulation), both PP3M and PP1M formulations exhibited comparable incidence of EPS-related TEAEs, TTO, and TTR in patients with schizophrenia.

Abstract
RATIONALE Hyperprolactinemia is considered a troubling adverse effect of antipsychotics. Direct comparisons among second generation antipsychotics are scant in clinical practice. We hypothesize prolactin-sparing second-generation antipsychotics may have differential effects on prolactin levels and that they may be influenced by sex. OBJECTIVES To explore the differential effect of three widely used prolactin-sparing antipsychotics, aripiprazole, quetiapine and ziprasidone, on prolactin plasma levels in first episode non-affective psychosis during a 1year of treatment. METHOD From October 2005 to January 2011 a prospective, randomized, open-label study was undertaken. 141 patients who were randomly allocated to aripiprazole (N=56), quetiapine (N=36) or ziprasidone (N=49) were analyzed. The main outcome was differences in prolactin plasma levels over 1year follow-up among the three antipsychotics. Prolactin levels had a skewed distribution and therefore they were log-transformed before statistical analyses. RESULTS Male patients on aripiprazole had a lower risk of suffering an increase on prolactin plasma levels (N=71; F=12.645; p<0.001). There was a gender effect with smaller changes in mean prolactin values only in males. Aripiprazole had a reduced risk of hyperprolactinemia (aripiprazole 19.6%) compared to quetiapine (44.4%) and ziprasidone (32.7%) (p=0.038); and quite similar findings were found when investigating males (p=0.040). No significant differences were found in females. The percentages of mild prolactin excess were: 14.3% on aripiprazole, 36.1% on quetiapine and 18.4% on ziprasidone (χ2=6.611 p=0.037). CONCLUSIONS Our findings provide additional evidence of differential effects of three sparing-prolactin antipsychotics on prolactin release and may help clinicians to decide among therapeutic options.

Abstract
Introduction Post hoc analyses (two single-arm studies) were conducted to determine the impact of once-monthly injection of paliperidone palmitate on functioning in adult patients with schizophrenia in the Asia–Pacific region. Methods Study 1 enrolled hospitalized patients with acute exacerbation of schizophrenia, and study 2 enrolled patients with recently diagnosed schizophrenia unsatisfactorily treated with oral antipsychotics. Patients received paliperidone palmitate, 150 mg eq. on day 1, 100 mg eq. on day 8, then once monthly (50–150 mg eq.) (study 1, days 36 and 64; study 2, 18 months). Functional status was evaluated by Personal and Social Performance score in both studies and employment only in study 2. Results In study 1, 54 of 184 patients (29.4%) with an unfavorable level of functioning at the baseline improved to a favorable level (Personal and Social Performance score greater than 70) at day 92. This improvement was significantly greater among patients with recently diagnosed schizophrenia (5 years or less) compared with patients with chronic schizophrenia (more than 5 years): 40% versus 22% (p < 0.0001). Improvements were observed in all four domains (socially useful activities, personal and social relationships, self-care, disturbing/aggressive behavior). In study 2, significant (p < 0.0001) improvement in functioning was observed at all visits, beginning at week 5. Almost half (48.7%, 247/507) of patients showed clinically meaningful improvement in functioning (i.e., 10 point or greater increase in Personal and Social Performance score) at month 18. The proportion of patients fully/partially employed was greater at all postbaseline visits (134 of 280, 47.9%, at month 18) as compared with the baseline. Conclusion Functioning, including employment, was improved after short-term, once-monthly paliperidone palmitate injection, and was sustained to 18 months in Asia–Pacific patients with schizophrenia.

Abstract
BACKGROUND Nonadherence to antipsychotic treatment increases the likelihood of relapse and progressive symptomatology in patients with schizophrenia. Atypical long-acting injectables, including paliperidone palmitate (PP), may increase adherence and improve symptoms. This study compared and assessed predictors of treatment patterns and symptom remission among schizophrenia patients treated with PP versus atypical oral antipsychotic therapy (OAT) in community behavioral health organizations (CBHOs). METHODS This retrospective cohort analysis evaluated 763 patients with schizophrenia and new (PP-N; N = 174) or continuing (PP-C; N = 308) users of PP, or new users of OAT (N = 281) at enrollment in the REACH-OUT study (2010-2013). Treatment outcomes assessed at 1 year were discontinuation, and adherence, measured by proportion of days covered (PDC) or medication possession ratio (MPR). Remission status was assessed using the Structured Clinical Interview for Symptoms of Remission (SCI-SR). A machine learning platform, Reverse Engineering and Forward Simulation (REFS™), was used to identify predictors of study outcomes. Multivariate Cox and generalized linear regressions estimated the adjusted hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals. RESULTS Among PP-N users, 27% discontinued their initial treatment regimen versus 51% (p < 0.001) of OAT users. PP-N (vs OAT; HR = 0.49 [0.31-0.76]) users and males (HR = 0.65 [0.46-0.92]) had significantly lower rates of discontinuation. Relative to OAT, PP-N had a 36% [31%-42%] higher MPR and a 10-fold increased achievement of PDC ≥80% (OR = 10.46 [5.72-19.76]). PP users were significantly more likely to achieve remission in follow-up (PP-N vs OAT: OR = 2.65 [1.39-5.05]; PP-C vs OAT: OR = 1.83 [1.03-3.25]). CONCLUSIONS Relative to OAT, PP was associated with improved adherence, less frequent treatment discontinuation, and improved symptom remission in this CBHO study population.

Abstract
BACKGROUND High-security hospital patients are often complex in presentation and are characterized by treatment resistance, medication nonadherence and history of violence. Paliperidone is licensed both as an oral and depot antipsychotic medication in the treatment of schizophrenia. Clinical trials have shown that paliperidone depot is well tolerated with similar efficacy to risperidone depot but with additional practical advantages. Whilst data exist for the effectiveness of paliperidone palmitate (PP), there are no studies involving patients in forensic settings or those with comorbid personality disorder. Our aim was to evaluate the effectiveness of PP on violence, aggression and personality disorder symptoms. METHODS This project was a retrospective service evaluation involving 11 patients, carried out in a high-security hospital. A combination of patient records and interviews with the treating consultant psychiatrist were used to ascertain a Clinical Global Impression (CGI) score, the effect of PP on specific personality disorder symptom domains (cognitive-perceptual, impulsive-behavioural dyscontrol and affective dysregulation) and incidents of violence and aggression. Engagement with occupational and psychological therapies was also evaluated. Metabolic parameters were reviewed. RESULTS A total of 6 out of 11 patients continued on PP, most of whom had schizophrenia and dissocial personality disorder with histories of violence. All showed improvement in the CGI score with associated benefits in the three personality symptom domains. Overall, two patients demonstrated a reduction in the risk of violence. There was improvement in engagement with occupational therapy and psychological work. No significant effects on metabolic parameters were noted although hyperprolactinaemia, albeit asymptomatic, was consistently recorded. CONCLUSIONS This pragmatic service evaluation of a small but complex patient group demonstrated, for the first time, that PP was effective in reducing violence as well as improving personality pathology across all dimensions: a finding which could have significant implications for management of such high-security patients.

Abstract
INTRODUCTION Paliperidone, the major active metabolite of risperidone, is a second-generation antipsychotic that has been developed as an extended-release (ER) oral formulation and a long-acting injectable paliperidone palmitate (PP) formulation. Paliperidone has demonstrated efficacy in the reduction of acute schizophrenia symptoms and clinical benefits were maintained also in the long-term treatments. Paliperidone ER and PP are generally well tolerated with a predictable adverse event profile. Areas covered: Data from studies evaluating safety and tolerability in the acute and maintenance treatment of schizophrenia with paliperidone are reviewed. The reported treatment-emergent adverse events of these formulations are discussed. Expert opinion: In the treatment of schizophrenia and schizoaffective disorders the safety profile has a central role because it can enhance patient compliance. In fact treatment-emergent adverse events are one of the main causes of discontinuation in these patients. In particular the main limitation in the administration of paliperidone could be represented by the onset of hyperprolactinemia (especially in women) and of mild parkinsonism. Paliperidone has a high impact on current long-term drug strategies, especially given the new 3 month long-acting injectable formulation of PP.

Abstract
RATIONALE Long-acting injectable (LAI) paliperidone palmitate 1-month formulation (PP1M) has demonstrated acceptable tolerability and favorable clinical outcomes in Western and Asian patients with schizophrenia. Hence, analysis of the outcomes of long-term PP1M treatment specifically in Chinese patients is of interest. OBJECTIVE The aim of this study is to evaluate the long-term safety and efficacy of PP1M treatment in Chinese patients with schizophrenia. METHODS In this 25-week, open-label, Phase IV study, patients (18-65 years) diagnosed with schizophrenia and having a baseline Positive and Negative Syndrome Scale (PANSS) total score of 60-120 (inclusive) were enrolled. All patients received injections of PP1M 150 mg eq. (day 1) and 100 mg eq. (day 8), followed by a flexible once-monthly maintenance dosing (75, 100, or 150 mg eq.). RESULTS Of the 353 patients, 234 (66.3%) completed the study treatment (mean age, 31.1 years; 52.7% men). The PANSS total score (primary end point) improved significantly over the 6-month treatment period (mean [standard deviation] change from baseline to end of treatment, -27.2 [18.30]; P<0.0001). The Clinical Global Impressions-Severity and Personal and Social Performance scores (secondary end points) also improved significantly (P<0.0001). At 6 months, PP1M had a positive impact on medication satisfaction, adherence, and increased preference for LAIs. Treatment-emergent adverse events (TEAEs) were reported by 181 (51.3%) patients (TEAEs ≥5%: extrapyramidal disorder [15.3%], akathisia [10.5%], blood prolactin increase [8.8%], insomnia [5.4%]). A total of 8 deaths were reported, including 4 completed suicides. CONCLUSION Long-term treatment with PP1M was efficacious, and no new safety concerns were identified in Chinese patients with schizophrenia. Overall, the results were comparable with observations from previous studies.

Abstract
OBJECTIVE There is evidence that over time health outcomes of people with schizophrenia are deteriorating rather than improving both in terms of mortality rate and levels of morbidity, even in Australia where service resourcing is substantial. Our objective was to examine the evidence of whether poor outcomes reflect decreases in treatment effectiveness and, if so, what are the barriers to improving standards of care. This review will argue that the confidence of clinicians to diagnose schizophrenia early, and provide assertive and long-term care, may be being undermined by a series of controversies in the published literature and discrepancies in clinical practice guidelines. METHOD A critical review was conducted of the evidence regarding six issues of high clinical relevance to the treatment of schizophrenia formulated as questions: (1) Is schizophrenia a progressive disease? (2) Does relapse contribute to disease progression and treatment resistance? (3) When should the diagnosis of schizophrenia be made? (4) Should maintenance antipsychotic medication be discontinued in fully remitted first-episode patients? (5) Do antipsychotic medications cause deleterious reductions in cortical grey matter volumes? and (6) Are long-acting injectable antipsychotics more effective in reducing relapse rate compared to oral formulations? RESULTS There is reliable evidence for schizophrenia being a progressive disease with emergent treatment resistance in most cases, that relapse contributes to this treatment resistance, that maintenance antipsychotic medication should not be discontinued in remitted first-episode patients, that antipsychotic medication does not appear to cause deleterious grey matter volume changes, that maintenance antipsychotic medication reduces the mortality rate in schizophrenia and that long-acting injectable antipsychotics are more effective in preventing relapse than oral formulations. CONCLUSION There is an urgent need to re-engineer the early management of schizophrenia and to routinely evaluate this type of innovation within practice-based research networks. A proposal for an assertive treatment algorithm is included.

Abstract
OBJECTIVE Patients with chronic schizophrenia suffer a huge burden, as do their families/caregivers. Treating schizophrenia is costly for health systems. The European Medicines Agency has approved paliperidone palmitate (PP-LAI; Xeplion), an atypical antipsychotic depot; however, its pharmacoeconomic profile in Portugal is unknown. A cost-effectiveness analysis was conducted from the viewpoint of the Portuguese National Health Service. METHODS PP-LAI was compared with long acting injectables risperidone (RIS-LAI) and haloperidol (HAL-LAI) and oral drugs (olanzapine; oral-OLZ) adapting a 1-year decision tree to Portugal, guided by local experts. Clinical information and costs were obtained from literature sources and published lists. Outcomes included relapses (both requiring and not requiring hospitalization) and quality-adjusted life-years (QALYs). Costs were expressed in 2014 euros. Economic outcomes were incremental cost-effectiveness ratios (ICERs); including cost-utility (outcome = QALYs) and cost-effectiveness analyses (outcomes = relapse/hospitalization/emergency room (ER) visit avoided). RESULTS The base-case cost of oral-OLZ was 4447€ (20% drugs/20% medical/60% hospital); HAL-LAI cost 4474€ (13% drugs/13% medical/74% hospital); PP-LAI cost 5326€ (49% drugs/12% medical/39% hospital); RIS-LAI cost 6223€ (44% drugs/12% medical/44% hospital). Respective QALYs/hospitalizations/ER visits were oral-OLZ: 0.761/0.615/0.242; HAL-LAI: 0.758/0.623/0.250; PP-LAI: 0.823/0.288/0.122; RIS-LAI: 0.799/0.394/0.168. HAL-LAI was dominated by oral-OLZ and RIS-LAI by PP-LAI for all outcomes. The ICER of PP-LAI over oral-OLZ was 14,247€/QALY, well below NICE/Portuguese thresholds (≈24,800€/30,000€/QALY). ICERs were 1973€/relapse avoided and 2697€/hospitalization avoided. Analyses were robust against most variations in input values, as PP-LAI was cost-effective over oral-OLZ in >99% of 10,000 simulations. CONCLUSION In Portugal, PP-LAI dominated HAL-LAI and RIS-LAI and was cost-effective over oral-OLZ with respect to QALYs gained, relapses avoided, and hospitalizations avoided.

Comparison of Capillary and Venous Plasma Drug Concentrations After Repeated Administration of Risperidone, Paliperidone, Quetiapine, Olanzapine, or Aripiprazole. Clin Pharmacol Drug Dev 2016; 5:538-547.

Abstract
Quantification of blood levels of antipsychotic drugs may be useful for managing medication therapy. This open‐label, parallel‐group study was performed to compare finger‐stick‐based capillary with corresponding venous plasma concentrations for risperidone, paliperidone, quetiapine, olanzapine, and aripiprazole and their major metabolites after repeated dosing in patients with schizophrenia or related illnesses. Finger‐stick‐based capillary and venous blood samples were collected at various times within a dosing interval. All drug concentration measurements in the derived plasma samples were performed with validated liquid chromatography–tandem mass spectrometry methods. Finger‐stick‐based capillary and venous plasma drug concentrations after repeated dosing were generally similar. Olanzapine capillary plasma concentrations, however, were on average approximately 20% higher than venous concentrations, with a trend for a relatively greater difference occurring shortly after dosing. In addition, smaller capillary–venous differences were observed for extended‐release and long‐acting intramuscular formulations and for aripiprazole, a drug with a long half‐life, compared with drugs administered as an immediate‐release formulation (risperidone, olanzapine). After repeated dosing, plasma derived from finger‐stick‐based blood was observed to be predictive of the venous concentrations. Capillary sampling may be an appropriate alternative to venous sampling to readily evaluate systemic drug concentrations.

Abstract
INTRODUCTION The atypical antipsychotic (APs) drugs have become the most widely used agents to treat a variety of psychoses because of their superiority with regard to safety and tolerability profile compared to conventional/'typical' APs. AREAS COVERED We aimed at providing a synthesis of most current evidence about the safety and tolerability profile of the most clinically used atypical APs so far marketed. Qualitative synthesis followed an electronic search made inquiring of the following databases: MEDLINE, Embase, PsycINFO and the Cochrane Library from inception until January 2016, combining free terms and MESH headings for the topics of psychiatric disorders and all atypical APs as following: ((safety OR adverse events OR side effects) AND (aripiprazole OR asenapine OR quetiapine OR olanzapine OR risperidone OR paliperidone OR ziprasidone OR lurasidone OR clozapine OR amisulpride OR iloperidone)). EXPERT OPINION A critical issue in the treatment with atypical APs is represented by their metabolic side effect profile (e.g. weight gain, lipid and glycaemic imbalance, risk of diabetes mellitus and diabetic ketoacidosis) which may limit their use in particular clinical samples. Electrolyte imbalance, ECG abnormalities and cardiovascular adverse effects may recommend a careful baseline and periodic assessments.

Abstract
OBJECTIVES To evaluate paliperidone palmitate (PP) effectiveness, safety and adherence to treatment. METHODS We collected data of all patients (n = 50) affected by Schizophrenia Disorders, treated with PP for a 3 month minimum period in the outpatient setting of Mental Health Department in Modena, from 01/01/2014 to 31/01/2015. We evaluated reasons and modality for PP implementation, improvement in symptom and functioning scales, adverse effects, discontinuations and relapses. We statistically correlated socio-demographic and clinical variables of our sample with PP therapeutic variables. RESULTS We registered an improvement in all scales, with a superior percentage in PANSS positive subscale. The mean PP dose in some patients was lower than official indications, although our sample was clinically severe. Illness relapses affected 60% and dropout 18% of patients. PP was well tolerated and in just a few cases adverse events required treatment interruption. The risk factors for discontinuation were represented by "lack of therapeutic compliance" (HR = 4.11, p < 0.0001) and "inefficacy" (HR = 1.67, p < 0.0001). CONCLUSIONS With limitations of observational design, this research highlights that PP was well tolerated and effective in improving both psychotic symptoms and functioning, but moderately effective in preventing relapse, probably due to clinical severity of our patients associated with extremely cautious and flexible PP prescriptions.

Abstract
BACKGROUND This double-blind, parallel-group, multicenter, phase-3 study was designed to test the noninferiority of paliperidone palmitate 3-month formulation (PP3M) to the currently marketed 1-month formulation (PP1M) in patients (age 18-70 years) with schizophrenia, previously stabilized on PP1M. METHODS After screening (≤3 weeks) and a 17-week, flexible-dosed, open-label phase (PP1M: day 1 [150mg eq. deltoid], day 8 [100mg eq. deltoid.], weeks 5, 9, and 13 [50, 75, 100, or 150mg eq., deltoid/gluteal]), clinically stable patients were randomized (1:1) to PP3M (fixed-dose, 175, 263, 350, or 525mg eq. deltoid/gluteal) or PP1M (fixed-dose, 50, 75, 100, or 150mg eq. deltoid/gluteal) for a 48-week double-blind phase. RESULTS Overall, 1016/1429 open-label patients entered the double-blind phase (PP3M: n=504; PP1M: n=512) and 842 completed it (including patients with relapse). PP3M was noninferior to PP1M: relapse rates were similar in both groups (PP3M: n=37, 8%; PP1M: n=45, 9%; difference in relapse-free rate: 1.2% [95% CI:-2.7%; 5.1%]) based on Kaplan-Meier estimates (primary efficacy). Secondary endpoint results (changes from double-blind baseline in positive and negative symptom score total and subscale scores, Clinical Global Impression-Severity, and Personal and Social Performance scores) were consistent with primary endpoint results. No clinically relevant differences were observed in pharmacokinetic exposures between PP3M and PP1M. Both groups had similar tolerability profiles; increased weight was the most common treatment-emergent adverse event (double-blind phase; 21% each). No new safety signals were detected. CONCLUSION Taken together, PP3M with its 3-month dosing interval is a unique option for relapse prevention in schizophrenia.

Abstract
Urinary incontinence, although rarely reported, is one of the most important adverse effects of antipsychotic medication. It can be an embarrassing, distressing, and potentially treatment-limiting. Several antipsychotics, including both typical and atypical varieties, are known to induce urinary incontinence. Many antipsychotic drugs target the neural pathways controlling continence by binding to receptors of some neurotransmitters such as serotonin, dopamine, acetylcholine, and adrenaline. Pharmacological management of incontinence should be considered if there is a risk of cessation of the antipsychotic therapy or any decline in patients’ compliance. Amitriptyline, desmopressin, ephedrine, and anticholinergics such as oxybutynin and trihexyphenidyl are the most frequently used agents to treat incontinence. We think that the frequency of incontinence is higher than reported in the literature, and that follow-up routines should include a form of standardized screening for all possible adverse effects, including incontinence, of any given antipsychotic. In this article, we report a case of urinary incontinence as an adverse effect of paliperidone palmitate use during maintenance therapy in a patient with schizophrenia.

Abstract
BACKGROUND Atypical long-acting injectable (LAI) antipsychotics are increasingly available for treating chronic schizophrenia in patients chronically non-adherent to prescribed regimens. Few economic studies have compared these products. PURPOSE To determine the cost-effectiveness of aripiprazole (ARI-LAI), paliperidone (PP-LAI), olanzapine (OLZ-LAI), and risperidone (RIS-LAI) in patients with chronic schizophrenia in Finland. METHODS A 1-year decision tree model was adapted with guidance from an expert panel. Patients started hospitalized in relapse; those who responded continued treatment, others were switched to secondary drugs, then clozapine in the event of 2nd line failure. Rates of adherence, stable disease, relapse, and hospitalization were taken from pivotal trials, and utilities from published research. Included were direct costs paid by the Finnish Ministry of Health, in 2015 euros. Outcomes included quality-adjusted life-years (QALYs), hospitalization rates, and rates of relapse not requiring hospitalization. Model robustness was assessed using a series of 1-way and multivariate sensitivity analyses. RESULTS Expected costs were lowest for PP-LAI at 41,148€, followed by 41,543€ for ARI-LAI, 42,067€ for RIS-LAI and 45,406€ for OLZ-LAI. Respective QALYs were 0.683, 0.671, 0.666, and 0.672. Re-hospitalization rates and non-admitted relapses were 23.6% and 3.9% for PP-LAI, 28.5% and 4.1% for ARI-LAI, 28.8% and 5.0% for RIS-LAI, 28.3% and 5.2% for OLZ-LAI. PP-LAI treatment was associated with the most days with stable disease (132.0), followed by OLZ-LAI (125.5), ARI-LAI (122.6), and RIS-LAI (114.4). Sensitive inputs between PP-LAI and ARI-LAI included rates of adherence, dropouts, and relapses plus drug prices; dropout and relapse rates for RIS-LAI; OLZ-LAI results were insensitive. In probability sensitivity analyses, PP-LAI dominated ARI-LAI in 75.8% of the 10,000 iterations, RIS-LAI in 83.1% and OLZ-LAI in 95.7%. CONCLUSIONS PP-LAI dominated the other atypicals. It appears to be the preferred option for treating chronic relapsing schizophrenia.

Abstract
Long-acting injectable antipsychotics (LAIs) were developed to make treatment easier, improve adherence, and/or signal the clinician when nonadherence occurs. Second-generation antipsychotic LAIs (SGA-LAIs) combine the advantages of SGA with a long-acting formulation. The purpose of this review is to evaluate the available literature concerning the impact of SGA-LAIs on patient functioning and quality of life (QOL). Although several studies regarding schizophrenia patients' functioning and QOL have been performed, the quantity of available data still varies greatly depending on the SGA-LAI under investigation. After reviewing the literature, it seems that SGA-LAIs are effective in ameliorating patient functioning and/or QOL of patients with schizophrenia, as compared with placebo. However, while methodological design controversy exists regarding the superiority of risperidone LAI versus oral antipsychotics, the significant amount of evidence in recently published research demonstrates the beneficial influence of risperidone LAI on patient functioning and QOL in stable patients and no benefit over oral treatment in unstable patients. However, the status of the research on SGA-LAIs is lacking in several aspects that may help physicians in choosing the correct drug therapy. Meaningful differences have been observed between SGA-LAIs in the onset of their clinical efficacy and in the relationships between symptoms and functioning scores. Moreover, head-to-head studies comparing the effects of SGA-LAIs on classical measures of psychopathology and functioning are available mainly on risperidone LAI, while those comparing olanzapine LAI with other SGA-LAIs are still lacking. Lastly, some data on their use, especially in first-episode or recent-onset schizophrenia and in refractory or treatment-resistant schizophrenia, is available.

Abstract
OBJECTIVE This commentary summarizes recommended dosing strategies for a recently developed 3 monthly long-acting injectable 1 (LAI) formulation of paliperidone palmitate (PP3M) for the treatment of schizophrenia in adults. METHODS Recommendations for different dosing scenarios are based on the pharmacokinetic, efficacy and safety outcomes from phase 1 and phase 3 studies, population pharmacokinetic models, and model based simulations. RESULTS Switching to PP3M treatment is recommended only in patients previously treated with once monthly paliperidone palmitate LAI (PP1M) for at least 4 months. The first injection of PP3M (175 to 525 mg equivalent [eq.]) should be given at the time of next scheduled injection of PP1M as a 3.5-fold multiple of the last PP1M dose (50-150 mg eq.), with a dosing window of ± 1 week. Following that first injection of PP3M, once-every-three-months maintenance injections with PP3M are recommended, with a dosing window of ± 2 weeks. The doses of PP3M can be administered in either deltoid (≥ 90 kg: 1.5 inch 22 G needle; <90 kg: 1.0 inch 22 G needle) or gluteal muscles (1.5 inch 22 G needle regardless of weight). In patients with mild renal impairment (creatinine clearance: 50-80 mL/min), a 25% dose reduction in PP1M and subsequent switching to a corresponding 3.5-dose multiple of PP3M (but not exceeding 350 mg eq.) is recommended. Appropriate dosing is recommended in elderly patients with diminished renal function not exceeding mild renal impairment. Similarly to PP1M, PP3M is not recommended in patients with moderate/severe renal impairment. Like PP1M, no dosage adjustment is required in patients with mild or moderate hepatic impairment or elderly patients with normal renal function. CONCLUSIONS These data provide clinical guidelines for the optimum use of PP3M in patients with schizophrenia previously treated with PP1M for at least 4 months. REGISTRATION ClinicalTrials.gov identifier: NCT01559272 and NCT01529515.

Abstract
Patient satisfaction with treatment is an important clinical index associated with the efficacy and adherence of treatment in schizophrenia. Although switching from oral antipsychotics to the long-acting injectable formulation may improve convenience, patient satisfaction has not been studied extensively. We carried out a 21-week, multicenter, randomized, open-label comparative study. A total of 154 patients with schizophrenia unsatisfied with current oral atypical antipsychotics were assigned randomly to either immediate or delayed switching to paliperidone palmitate, the long-acting injectable formulation of paliperidone. The Medication Satisfaction Questionnaire (MSQ) and the Treatment Satisfaction Questionnaire for Medication (TSQM) were used to evaluate patient satisfaction with treatment, whereas the Positive and Negative Syndrome Scale (PANSS) and the Personal and Social Performance (PSP) scale were used to evaluate efficacy. From baseline to the final assessment, the MSQ score increased significantly in both groups, and the increase was greatest after the first administration of paliperidone palmitate in the immediate switch group. The scores of TSQM effectiveness, convenience, and global satisfaction as well as the PSP total score increased significantly, whereas the PANSS total score decreased significantly in both groups. The immediate switch group showed a significant improvement in the TSQM convenience score compared with the delayed switch group on oral antipsychotics during the comparison period. Most adverse events were minor and tolerable. In short, switching from oral atypical antipsychotics to paliperidone palmitate because of poor satisfaction significantly improved patient satisfaction, with comparable efficacy and tolerability.

Abstract
This multicenter, randomized, open-label, parallel-group, phase-1 study assessed the pharmacokinetics (PK), safety, and tolerability of the investigational intramuscular paliperidone palmitate 3-month (PP3M) formulation in patients with schizophrenia or schizoaffective disorder. A total of 328 patients (men or women, aged 18-65 years) were enrolled in 1 of 4 separately conducted panels (A to D). Each panel had 2 single-dose treatment periods (period 1, 1 mg intramuscular paliperidone immediate release [IR]; period 2, intramuscular PP3M 75-525 mg eq) separated by a washout of 7-21 days. Overall, 245 of 308 (79.5%) PP3M-dosed patients completed the study. Because the PK studies of panels A and C were compromised by incomplete injection in some patients, PK data from only panels B and D are presented. Safety data from all panels are presented. Peak paliperidone plasma concentration was achieved between 23 and 34 days, and apparent half-life was ∼2-4 months. Mean plasma AUC∞ and Cmax of paliperidone appeared to be dose-proportional. Relative bioavailability in comparison with paliperidone was ∼100% independent of the dose and injection site. Headache and nasopharyngitis were the most common (>7%) treatment-emergent adverse events. Overall, safety and tolerability were similar to those of the 1-month formulation. Results support a once-every-3-months dosing interval in patients with schizophrenia or schizoaffective disorder.

Abstract
We present detailed data on the efficacy and safety profile of paliperidone palmitate once-monthly long acting injectable (PP1M-LAI) in the treatment of schizophrenia in an elderly Caucasian woman. PP1M-LAI was initiated with starting doses of 150 and 100 mg on treatment days 1 and 8, respectively. Subsequent 100 mg doses of PP1M-LAI were then administered at 4-weekly intervals. The primary efficacy variable was the change in Positive and Negative Syndrome Scale (PANSS) total score from baseline. Safety assessment variables included assessment of treatment emergent adverse events, clinical laboratory tests, vital sign measurements, ECG, Calgary Depression Scale for Schizophrenia (CDSS), mini-mental status examination, Abnormal Involuntary Movement Scale (AIMS), Barnes Akathisia Rating Scale (BARS), Simpson-Angus Scale for the Assessment of Extrapyramidal Side Effects (SAS) and WHO Quality of Life-BREF (WHO-QOL-BREF). The aforementioned variables were all monitored for changes from baseline over a period of 28 weeks. A reduction of PANSS total score was noted over the 28 weeks, demonstrating the efficacy of PP1M-LAI for the treatment of schizophrenia in our patient. Improvements were also noted in the BARS score, SAS score and WHO-QOL-BREF. Negative findings were observed with regard to several pre-established safety variables such as blood glucose levels, prolactin levels, QTC intervals and weight. Overall, the addition of PP1M-LAI to the treatment regime improved the control of psychotic symptoms. However, iatrogenic consequences arising from the use of PP1M-LAI need to be considered and balanced against the primary efficacy of the medication.

Abstract
Hyperprolactinemia is a common adverse in vivo effect of antipsychotic medications that are used in the treatment of patients with schizophrenia. Here, we compared the effects of two atypical antipsychotics, paliperidone and aripiprazole, on cAMP/calcium signaling and prolactin release in female rat pituitary lactotrophs in vitro. Dopamine inhibited spontaneous cAMP/calcium signaling and prolactin release. In the presence of dopamine, paliperidone rescued cAMP/calcium signaling and prolactin release in a concentration-dependent manner, whereas aripiprazole was only partially effective. In the absence of dopamine, paliperidone stimulated cAMP/calcium signaling and prolactin release, whereas aripiprazole inhibited signaling and secretion more potently but less effectively than dopamine. Forskolin-stimulated cAMP production was facilitated by paliperidone and inhibited by aripiprazole, although the latter was not as effective as dopamine. None of the compounds affected prolactin transcript activity, intracellular prolactin accumulation, or growth hormone secretion. These data indicate that paliperidone has dual hyperprolactinemic actions in lactotrophs i) by preserving the coupling of spontaneous electrical activity and prolactin secretion in the presence of dopamine and ii) by inhibiting intrinsic dopamine receptor activity in the absence of dopamine, leading to enhanced calcium signaling and secretion. In contrast, aripiprazole acts on prolactin secretion by attenuating, but not abolishing, calcium-secretion coupling.

Abstract
This open-label, single-arm, multicenter, 13-week, prospective study explored the efficacy, safety, and tolerability of paliperidone palmitate (150 milligram equivalents [mg eq] [day 1], 100 mg eq [day 8], both deltoid injections; 75-150 mg eq, deltoid/gluteal injection) in Chinese patients with acute schizophrenia (Positive and Negative Syndrome Scale [PANSS] total score ≥70), who previously had unsatisfactory therapeutic effect following oral antipsychotic treatment (without washout period). Primary efficacy endpoint was percentage of patients with ≥30% improvement in the PANSS total score at the end of 13 weeks. Secondary efficacy endpoints included change from baseline to end of week 13 in PANSS total score, PANSS subscale scores, Marder factor scores, Clinical Global Impressions-Severity score, and Personal and Social Performance Scale scores. Overall, 477/610 enrolled patients (full analysis set, 78.2%) completed the study (men: 55.1%; women: 44.9%; mean age: 31.5 years). Total, 443/610 (72.6%, full analysis set) patients achieved primary endpoint (mean [standard deviation] change from baseline: -30.9 [19.51]). All secondary endpoints demonstrated significant improvement at the end of 13 weeks. One death occurred during this acute phase. The most common (>5%) treatment-emergent adverse events were extrapyramidal disorders (8.4%). The efficacy and safety data are consistent with other short-term, placebo-controlled studies of paliperidone palmitate conducted in similar populations.

Abstract
OBJECTIVE To evaluate the efficacy, safety, and impact on hospitalizations of long-acting injectable paliperidone palmitate (PP) treatment, in patients with recent-onset schizophrenia who had not responded satisfactorily to oral antipsychotics. METHODS In this 18-month, open-label, Phase-IIIb study from Asia-Pacific region, patients (18-50 years) with recent-onset (≤5 years) schizophrenia unsatisfactorily treated with previous oral antipsychotics were initiated on PP 150 mg eq on day 1, 100 mg eq on day 8, followed by flexible once monthly maintenance doses of 50-150 mg eq. The number and duration of hospitalizations were compared using a mirror analysis method between two periods: retrospective (12 months before PP initiation) and prospective (12 and 18 months after PP treatment) periods. RESULTS A total of 303 out of 521 (58%) patients (mean age, 28.7 years; 65.5% men, 92.5% Asian) completed the study. Positive and Negative Syndrome Scale (PANSS) total score improved significantly from baseline to month 18 (mean [standard deviation, SD] change: -11.3 [21.38], P<0.0001, primary endpoint). Subgroup analysis revealed greater improvements among patients with worse disease severity at baseline: PANSS ≥70 versus <70 (mean [SD] change: -23.1 [24.62] vs -4.7 [15.98], P<0.0001 each). Secondary efficacy endpoints such as Clinical Global Impression of Schizophrenia (CGI-SCH), Medication Satisfaction Questionnaire (MSQ) scores showed significant improvements (P<0.0001) from baseline; 33.3% patients achieved symptom remission. In mirror analyses set (N=474), PP significantly (P<0.0001) reduced mean number of hospitalization days/person/year (12-month: 74.3 vs 19.7; 18-month: 74.3 vs 18.9) as well as percentage of patients requiring hospitalization in past 12 months (12-month: 39.7% vs 24.6%; 18-month: 39.7% vs 25%), and PP treatment increased the proportion of patients not requiring hospitalization (12-month: 60.3% vs 75.4%; 18-month: 60.3% vs 75%) from retrospective to prospective period. Adverse events (≥15%) were extrapyramidal symptoms-related (31.3%), injection-site pain (18.6%), and insomnia (15.2%). CONCLUSION PP was efficacious and generally tolerable with significant reductions observed in both number of hospitalizations and days spent in hospital.

Abstract
BACKGROUND To assess the tardive dyskinesia (TD) rate in studies of once-monthly long-acting injectable (LAI) paliperidone palmitate (PP) and once-daily oral paliperidone extended release (Pali ER). METHODS Completed schizophrenia and bipolar studies for PP and Pali ER (≥ 6 month duration with retrievable patient-level data) were included in this post hoc analysis. Schooler-Kane research criteria were applied using Abnormal Involuntary Movement Scale (AIMS) scores to categorise probable (qualifying AIMS scores persisting for ≥ 3 months) and persistent TD (score persisting ≥ 6 months). Spontaneously reported TD adverse events (AEs) were also summarised. Impact of exposure duration on dyskinesia (defined as AIMS total score ≥ 3) was assessed by summarising the monthly dyskinesia rate. RESULTS In the schizophrenia studies, TD rates for PP (four studies, N = 1689) vs. Pali ER (five studies, N = 2054), were: spontaneously reported AE, 0.18% (PP) vs. 0.10% (Pali ER); probable TD, 0.12% (PP) vs. 0.19% (Pali ER) and persistent TD, 0.12% (PP) vs. 0.05% (Pali ER). In the only bipolar study identified [Pali ER (N = 614)], TD rate was zero (spontaneously reported AE reporting, probable and persistent TD assessments). Dyskinesia rate was higher within the first month of treatment with both PP (13.1%) and Pali ER (11.7%) and steadily decreased over time (months 6-7: PP: 5.4%; Pali ER: 6.4%). Mean exposure: PP, 279.6 days; Pali ER, 187.2 days. CONCLUSIONS Risk of TD with paliperidone was low (< 0.2%), regardless of the formulation (oral or LAI), in this clinical trial dataset. Longer cumulative exposure does not appear to increase the risk of dyskinesias.

Abstract
INTRODUCTION Several long-acting injectable (LAI) second-generation antipsychotics are now available for the management of schizophrenia. As patients with schizophrenia frequently present with diverse and challenging symptoms, it is important to understand the effects of antipsychotics in treating these different symptom subgroups and the timing of these responses. AREAS COVERED For this review, data from two randomized, double-blind trials were analyzed in respect to the onset and persistence of effects on several measures of psychopathology (as measured by the Positive and Negative Syndrome Scale [PANSS]) after treatment with LAI paliperidone palmitate (PP) (NCT00590577 and NCT00589914). EXPERT OPINION Symptom reductions from baseline with PP were significant by day 4 for all five PANSS factors in both studies. Some effects may have been driven by the presence or absence of a placebo response. A significant effect for PP versus placebo was observed for all major symptom domains for one or more doses of PP during the first month of treatment. Once established, most (but not all) significant responses persisted to the end point. Similar improvements were observed in PANSS scores with PP and oral risperidone. Dose-dependent trends were observed for the effect of PP on positive, negative and uncontrolled hostility/excitement symptoms.

Abstract
AIMS To determine the cost-effectiveness of long-acting injectable (LAI) antipsychotics for chronic schizophrenia in Sweden. METHODS A 1-year decision tree was developed for Sweden using published data and expert opinion. Five treatment strategies lasting 1 year were compared: paliperidone palmitate (PP-LAI), olanzapine pamoate (OLZ-LAI), risperidone (RIS-LAI), haloperidol decanoate (HAL-LAI) and olanzapine tablets (oral-OLZ). Patients intolerant/failing drugs switched to another depot; subsequent failures received clozapine. Resources and employment time lost (indirect costs) were costed in 2011 Swedish kroner (SEK), from standard government lists. The model calculated the average cost/patient and quality-adjusted life-years (QALYs), which were combined into incremental cost-effectiveness ratios. Multivariate and 1-way sensitivity analyses tested model stability. RESULTS PP-LAI followed by OLZ-LAI had the lowest cost/patient (189,696 SEK) and highest QALYs (0.817), dominating in the base case. OLZ-LAI followed by PP-LAI cost 229,775 SEK (0.812 QALY), RIS-LAI followed by HAL-LAI cost 221,062 SEK (0.804 QALY), HAL-LAI followed by oral-OLZ cost 243,411 SEK (0.776 QALY), and oral-OLZ followed by HAL-LAI cost 249,422 SEK (0.773 QALY). The greatest proportions of costs (52.5-83.8%) were for institutional care; indirect costs were minor (2.4-3.8%). RESULTS were sensitive to adherence and hospitalization rates, but not drug cost. PP-LAI followed by OLZ-LAI dominated OLZ-LAI followed by PP-LAI in 59.4% of simulations, RIS-LAI followed by HAL-LAI in 65.8%, HAL-LAI followed by oral-OLZ in 94.0% and oral-OLZ followed by HAL-LAI in 95.9%; PP-LAI followed by OLZ-LAI was dominated in 1.1% of the 40,000 iterations. CONCLUSION PP-LAI followed by OLZ-LAI was cost-effective in Sweden for chronic schizophrenia and cost-saving overall to the healthcare system.

Abstract
Since the 1970s, clinicians have increasingly become more familiar with hyperprolactinemia (HPRL) as a common adverse effect of antipsychotic medication, which remains the cornerstone of pharmacological treatment for patients with schizophrenia. Although treatment with second-generation antipsychotics (SGAs) as a group is, compared with use of the first-generation antipsychotics, associated with lower prolactin (PRL) plasma levels, the detailed effects on plasma PRL levels for each of these compounds in reports often remain incomplete or inaccurate. Moreover, at this moment, no review has been published about the effect of the newly approved antipsychotics asenapine, iloperidone and lurasidone on PRL levels. The objective of this review is to describe PRL physiology; PRL measurement; diagnosis, causes, consequences and mechanisms of HPRL; incidence figures of (new-onset) HPRL with SGAs and newly approved antipsychotics in adolescent and adult patients; and revisit lingering questions regarding this hormone. A literature search, using the MEDLINE database (1966-December 2013), was conducted to identify relevant publications to report on the state of the art of HPRL and to summarize the available evidence with respect to the propensity of the SGAs and the newly approved antipsychotics to elevate PRL levels. Our review shows that although HPRL usually is defined as a sustained level of PRL above the laboratory upper limit of normal, limit values show some degree of variability in clinical reports, making the interpretation and comparison of data across studies difficult. Moreover, many reports do not provide much or any data detailing the measurement of PRL. Although the highest rates of HPRL are consistently reported in association with amisulpride, risperidone and paliperidone, while aripiprazole and quetiapine have the most favorable profile with respect to this outcome, all SGAs can induce PRL elevations, especially at the beginning of treatment, and have the potential to cause new-onset HPRL. Considering the PRL-elevating propensity of the newly approved antipsychotics, evidence seems to indicate these agents have a PRL profile comparable to that of clozapine (asenapine and iloperidone), ziprasidone and olanzapine (lurasidone). PRL elevations with antipsychotic medication generally are dose dependant. However, antipsychotics having a high potential for PRL elevation (amisulpride, risperidone and paliperidone) can have a profound impact on PRL levels even at relatively low doses, while PRL levels with antipsychotics having a minimal effect on PRL, in most cases, can remain unchanged (quetiapine) or reduce (aripiprazole) over all dosages. Although tolerance and decreases in PRL values after long-term administration of PRL-elevating antipsychotics can occur, the elevations, in most cases, remain above the upper limit of normal. PRL profiles of antipsychotics in children and adolescents seem to be the same as in adults. The hyperprolactinemic effects of antipsychotic medication are mostly correlated with their affinity for dopamine D2 receptors at the level of the anterior pituitary lactotrophs (and probably other neurotransmitter mechanisms) and their blood-brain barrier penetrating capability. Even though antipsychotics are the most common cause of pharmacologically induced HPRL, recent research has shown that HPRL can be pre-existing in a substantial portion of antipsychotic-naïve patients with first-episode psychosis or at-risk mental state.
