Abstract
BACKGROUND AND OBJECTIVE A model-informed drug development (MIDD) approach was implemented for paliperidone palmitate (PP) 6-month (PP6M) clinical development, using pharmacokinetics and pharmacokinetic/pharmacodynamic model-based simulations. METHODS PP6M pharmacokinetics were simulated by extending the PP 3-month (PP3M) pharmacokinetic model to account for increased injection volume, and hence dose. Contribution of the MIDD approach to the design of the pivotal PP6M phase-3 study (PP6M/PP3M noninferiority study, NCT03345342) investigating schizophrenia relapse rates was twofold: (1) PP6M dose selection, and (2) hypothesis generation that lower trough concentrations (Ctrough) associated with PP6M, relative to PP3M, were not associated with lower efficacy, which was to be evaluated in the phase-3 study. Moreover, accompanied by an intense sampling scheme to adequately characterize paliperidone pharmacokinetics and to elucidate the potential relationship between concentration and safety/efficacy, the bridging strategy eliminated the need for additional phase-1/phase-2 clinical studies. RESULTS Using a MIDD bridging strategy, PP6M doses were selected that, compared with PP3M, were expected to have a similar range of exposures and a noninferior relapse rate and safety profile. Clinical data from PP6M/PP3M noninferiority study confirmed that PP6M, compared with PP3M, had a similar range of exposures (T'jollyn et al. in Eur J Drug Metab Pharmacokinet 2024), as well as a noninferior relapse rate and safety profile (this manuscript). CONCLUSIONS Consistency of the MIDD approach with observed clinical outcomes confirmed the hypothesis that lower Ctrough did not lead to increased relapse rates at the doses administered. Although higher paliperidone peak concentrations are achieved with corresponding doses of PP6M relative to PP3M in the phase-3 clinical study, types and incidences of treatment-related adverse events were comparable between PP6M and PP3M groups and no new safety concerns emerged for PP6M (Najarian et al. in Int J Neuropsychopharmacol 25(3):238-251, 2022).

Abstract
BACKGROUND Paliperidone palmitate 3-monthly (PP3M) has been tested in 1-year controlled studies. The aim of this study was to examine the relapse outcomes with PP3M monotherapy at 3 years in patients with schizophrenia. METHODS This was an observational, non-interventional study of patients started on PP3M according to their clinical need. All patients had a diagnosis of schizophrenia (ICD-10 F20) and were between 18 and 65 years of age. The study took place in a mental health facility in South East London, UK. RESULTS Among the 166 patients who started PP3M, 97 (58%) met inclusion criteria and were observed for 36 months. In total, five patients (5%) experienced a relapse (defined as step-up in clinical care) while on PP3M. There were no relapses between months 18 and 36. Of the original 97 patients, 56 (58%) remained on PP3M monotherapy at 3 years, and 71 (73%) remained on either PP3M or paliperidone palmitate one-monthly. Reasons for discontinuation of PP3M included patient refusal (n = 11, 33% of discontinuations) and adverse effects in (n = 8, 24%). CONCLUSION PP3M is a highly effective monotherapy treatment for reducing relapse in people with schizophrenia.

A population-based cohort study of 456,003 patients. Mol Psychiatry 2023; 28:5328-5336. [PMID: 37479782 DOI: 10.1038/s41380-023-02154-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 06/06/2023] [Accepted: 06/19/2023] [Indexed: 07/23/2023]
Abstract
An important step to improve outcomes for patients with schizophrenia is to understand treatment patterns in routine practice. The aim of the current study was to describe the long-term management of patients with schizophrenia treated with antipsychotics (APs) in real-world practice. This population-based study included adults with schizophrenia and who had received ≥3 deliveries of an AP from 2012-2017, identified using a National Health Data System. Primary endpoints were real-life prescription patterns, patient characteristics, healthcare utilization, comorbidities and mortality. Of the 456,003 patients included, 96% received oral APs, 17.5% first-generation long-acting injectable APs (LAIs), and 16.1% second generation LAIs. Persistence rates at 24 months after treatment initiation were 23.9% (oral APs), 11.5% (first-generation LAIs) and 20.8% (second-generation LAIs). Median persistence of oral APs, first-generation LAIs and second-generation LAIs was 5.0, 3.3, and 6.1 months, respectively. Overall, 62.1% of patients were administered anxiolytics, 45.7% antidepressants and 28.5% anticonvulsants, these treatments being more frequently prescribed in women and patients aged ≥50 years. Dyslipidemia was the most frequent metabolic comorbidity (16.2%) but lipid monitoring was insufficient (median of one occasion). Metabolic comorbidities were more frequent in women. Standardized patient mortality remained consistently high between 2013 and 2015 (3.3-3.7 times higher than the general French population) with a loss of life expectancy of 17 years for men and 8 years for women. Cancer (20.2%) and cardiovascular diseases (17.2%) were the main causes of mortality, and suicide was responsible for 25.4% of deaths among 18-34-year-olds. These results highlight future priorities for care of schizophrenia patients. The global persistence of APs used in this population was low, whereas rates of psychiatric hospitalization remain high. More focus on specific populations is needed, such as patients aged >50 years to prevent metabolic disturbances and 18-34-year-olds to reduce suicide rates.

Abstract
Background The paliperidone palmitate 6-month (PP6M) long-acting injectable formulation is currently the longest dosing interval available for schizophrenia treatment. Objective To compare treatment outcomes between a real-world external comparator arm (ECA; NeuroBlu database) and the PP6M open-label extension (OLE) clinical trial arm. Methods The ECA comprised patients receiving PP 1-month (PP1M) or PP 3-month (PP3M) for ⩾12 months without a relapse. The PP6M OLE arm included patients with PP1M treatment prior to randomization who completed the 12-month double-blind PP6M study on either PP3M or PP6M relapse-free. Inverse probability treatment weighting (IPTW) was used to study time-to-relapse (primary outcome) and change in Clinical Global Impressions-Severity (CGI-S) score (secondary outcome). Results At 24 months, 3.9% (7/178) of patients in the PP6M cohort experienced a relapse versus 15.6% (26/167) in the ECA. Time-to-relapse was longer in the PP6M cohort versus the ECA at 12-, 18-, and 24-months across the different weighting methods; median time-to-relapse was not reached in both cohorts. Hazard ratio (HR) for relapse was significantly lower for the PP6M cohort versus the ECA throughout the duration of the study [HR at 24 months: 0.18 (95% CI: 0.08-0.42), p < 0.001]. At 24 months, change in CGI-S score for the PP6M cohort was 0.76 points lower than the ECA (p < 0.001). Results were similar in a sensitivity analysis using propensity score matching (PSM); IPTW resulted in larger sample sizes in balanced dataset than PSM. Conclusion Consistent findings across weighting and matching methods suggest PP6M efficacy in reducing and delaying relapses and long-term symptom control compared to PP1M/PP3M in usual-care settings. Additional confounds, such as greater illness severity and more frequent comorbidities and comedications in the ECA, were not fully controlled by the applied statistical methods. Future real-world studies directly comparing PP6M with PP3M/PP1M and adjusting for these confounders are warranted.

Drug Healthc Patient Saf 2023; 15:113-123.

Abstract
Paliperidone palmitate 3-monthly (PP3M), an approved maintenance treatment for patients with schizophrenia, was the first long-acting antipsychotic injectable (LAI) to require only four administrations per year. Here, we aimed to review the available evidence about its use in the management of schizophrenia to date and highlight key study findings in order to provide a balanced overview of current experience in clinical practice. For that purpose, an extensive search of available literature from PubMed, Embase, and Web of Science was conducted in March 2023. Emerging data from real-world studies appear to signal that the benefits of the use of PP3M may well extent beyond the obvious convenience for patients and resource efficiency for services and may be actually associated with improved effectiveness and patient satisfaction. Large naturalistic studies from Australia, Europe and the US comparing treatment continuation between newer LAIs and/or oral antipsychotics showed that patients treated with PP3M had higher compliance rates and a longer period of continuous use. The risk of relapse, re-hospitalization and number of bed days was also lower with PP3M compared to PP1M and other LAIs as demonstrated by several cohort studies. Furthermore, patients treated with PP3M were using lower doses of benzodiazepines and concomitant oral antipsychotics compared with other LAIs. What is more, PP3M appears to positively impact patients' satisfaction and quality of life, facilitating long-term goals. In fact, recent studies recorded better quality-adjusted life years and decreased stigma, with improved social acceptability and promotion of rehabilitation for patients transitioning to PP3M. The rates of general satisfaction rates with PP3M were also higher among psychiatrists and caregivers who reported overall less concerns. In conclusion, clinical exposure and a growing body of evidence thus far, reinforce the use of PP3M in an effort to enhance patient outcomes alongside individual experience and treatment persistence.

Abstract
Introduction Poor adherence to antipsychotic medication is common in the treatment of schizophrenia and other psychotic disorders. Paliperidone palmitate 3-monthly (PP3M) is the first long-acting injectable (LAI) antipsychotic to allow for only four medication administrations per year, and although there is sufficient information available about the clinical effects, there is relatively limited insight into the subjective experience of people with lived experience. Methods This descriptive, cross-sectional survey explored patient's satisfaction and perspectives on the advantages and disadvantages of switching from monthly to 3-monthly paliperidone while also reporting on perceived levels of safety with regard to the reducing dose regimen during the Covid-19 pandemic. Information on discontinuation and hospitalisation rates at one year was also collected from the electronic records. Results Of the 46 patients included in the study, the vast majority reported feeling satisfied (89.2%) and safer (93.5%) after switching to the three-monthly formulation. Participants highlighted several advantages of changing to PP3M, most notably convenience (93.5%), improved quality of life (58.7%), decreased stigma (39.1%) and better adherence (28.3%). Furthermore, 93.5% of respondents experienced no disadvantages, while 6.5% described worsening side effects or symptoms. In fact, only one patient discontinued PP3M at one year with the overall number of hospitalisations also reducing in the same period compared to the year before switching. Discussion Our findings add to the small, but growing, body of evidence supporting patient satisfaction and acceptance with the use of PP3M and may reinforce the use of less frequent LAIs in clinical practice to enhance individual experience and treatment persistence and decrease levels of stigmatisation.

Abstract
BACKGROUND Long-acting injectable paliperidone can improve adherence in psychotic patients and reduce relapses and healthcare resource utilization (HRU). This study compares the effectiveness of the three-monthly paliperidone palmitate (PP3M) with the one-monthly formulation (PP1M) and investigates reasons that hinder the use of PP3M in real-world settings. METHODS The authors conducted a three-phase observational study. For subjects recruited from six psychiatric services in Milan, HRU outcomes of PP3M prescription were evaluated through a 12-month mirror-image design (phase 1) and a comparison of HRU of PP1M-only subjects and PP3M subjects during the year prior to PP3M initiation (phase 2). Lastly, they conducted a survey among physicians concerning reasons for not switching to PP3M (phase 3). RESULTS A total of 119 subjects (61 on PP3M and 58 on PP1M) were included. One year after PP3M initiation, outpatients' visits decreased significantly. Comparing PP3M with PP1M subjects, no significant difference was found in HRU. Perception of patient's unstable clinical condition was the main reason for maintaining PP1M (32.8%), followed by the need for monthly monitoring (19.7%). CONCLUSION PP3M initiation was associated with an overall HRU reduction. Subjects switched to PP3M had similar HRU when compared to those who did not, suggesting similar clinical conditions in both groups.

Abstract
BACKGROUND: In the United States, most patients with schizophrenia have Medicaid coverage. Antipsychotic treatments are the cornerstone of schizophrenia management; most patients are treated with daily oral antipsychotics but struggle with medication adherence. Evidence suggests that medication adherence is inversely correlated with dosing frequency. Once-monthly paliperidone palmitate (PP) has been demonstrated to improve adherence compared with oral antipsychotics; transitioning to once-every-3-months PP (PP3M) further improved adherence. In 2021, once-every-6-months PP (PP6M) was approved by the US Food and Drug Administration to provide even longer between-dose intervals. Public health stakeholders who aim to improve medication adherence are interested in understanding how introducing PP6M to the formulary will impact the budget. OBJECTIVE: To evaluate the budget impact of introducing PP6M to the formulary from the perspectives of a hypothetical US multistate health care payer and state Medicaid programs using California, Georgia, and Ohio as examples. METHODS: The budget impact model was developed from a payer perspective, comparing the reference scenario (without PP6M in the market) with a new scenario (with PP6M). The study population included patients with schizophrenia who were eligible to receive PP6M. Market shares were assigned to the reference and new market scenarios. Efficacy was measured by the relative risk of relapse while receiving treatment. Adherence effects were included in the model and affected costs of treatment and relapse rates. A deterministic 1-way sensitivity analysis was performed. RESULTS: Base-case results for a multistate payer with 1 million members demonstrate that adding PP6M to the market results in total incremental plan-level costs ranging from $7,747 in year 1 to $11,501 in year 5. Increased drug costs were offset by administration and relapse cost savings ($105 and $881 in year 5, respectively). The average incremental cost per treated patient per year was stable at $180.06 for each year, and the incremental cost per member per month stayed below $0.01 for each year. The results of the model from the state-level Medicaid scenarios are broadly similar to those of the multistate base-case perspective. The 1-way sensitivity analysis demonstrated the model is most sensitive to the per-package costs of PP6M and PP3M, along with the proportion of patients fully adherent with PP3M. CONCLUSIONS: The budget impact of introducing PP6M as a treatment option is minimal. With the expected cost offsets from reduced administration and relapse costs due to adherence benefits, these results suggest that PP6M can be a viable treatment option from a clinical and a budgetary perspective.

Abstract
International guidelines suggest long-term antipsychotic therapies for treating schizophrenia; however, medication compliance remains a critical issue in schizophrenia. Paliperidone palmitate (PP) is a second-generation antipsychotic long-acting injectable (SGA-LAI) approved for the treatment of schizophrenia. To date, the majority of studies on PP compliance patterns did not use specific instruments to assess medications' adherence, have been performed in not naturalistic samples and present partially overlapping populations. We conducted a systematic review in which we aimed to review the current knowledge on PP-LAI adherence levels and to describe healthcare resource utilisation and costs related to PP-LAI treatment. The evaluation has been conducted by searching in different databases (PubMed, Ovid, Scopus, and Cochrane Library) from inception to September 2022. Our findings suggest that paliperidone palmitate should be considered a good treatment strategy for patients affected by schizophrenia: PP showed both a good efficacy and tolerability and better adherence patterns and more favourable healthcare resource utilisation and costs, compared to OA.

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
BACKGROUND Daily injections of recombinant human growth hormone are the standard of care to treat growth failure due to pediatric growth hormone deficiency (GHD). While effective, daily injections are burdensome and can compromise adherence. In recent years, novel injection treatments requiring less frequent administration for growth hormone deficiency (GHD) have been developed. A targeted, pragmatic literature review was conducted to summarize and document the patient experience of moving from daily to less frequent injections, with a specific focus on changing from daily to weekly injection treatments in pediatric GHD (pGHD). OBJECTIVE Explore and describe the patient experience when switching from a daily to a less frequent injection schedule for GHD. METHODS Targeted literature searches were conducted to identify literature describing the patient experience of moving from a daily to weekly injection in GHD. Supplementary searches were conducted to identify literature describing the patient experience of moving from daily to less frequent injection regimens in other medical conditions. RESULTS Across searches, 1,691 abstracts were reviewed and 13 articles were included in the final analysis. These publications reported that patients moving to less frequent injections across a variety of conditions, including GHD, experienced increased convenience and satisfaction, higher adherence rates, fewer adverse events, and improved quality of life. Less frequent injections were also reported to be at least as efficacious as daily treatments. CONCLUSIONS Less frequent injections in GHD and as other conditions are less burdensome, positively benefit patients, and result in improved adherence that may lead to improved clinical outcomes. Clinicians may consider weekly regimens as an effective alternative for patients, in particular in pGHD, especially when missed injections can negatively impact treatment outcomes. More research is needed to better understand the real-world benefits of injectable therapies that require less frequent administration (e.g., weekly versus daily).

One-Month versus Three-Month Formulation of Paliperidone Palmitate Treatment in Psychotic Disorders: Patients', Relatives', and Mental Health Professionals' Perspectives. Patient Prefer Adherence 2022; 16:615-624. [PMID: 35283623 PMCID: PMC8904433 DOI: 10.2147/ppa.s349460] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/15/2021] [Accepted: 02/10/2022] [Indexed: 11/23/2022] Open
Abstract
PURPOSE Paliperidone palmitate is the only available long acting injectable (LAI) antipsychotic with a monthly and three-monthly formulation. LAIs may help battle non-adherence. Studies about the experiences of switching from the monthly (PP1M) to the three-monthly formulation (PP3M) of paliperidone are scarce. Therefore, the aim of this study is to evaluate the perspectives of patients, relatives, and mental health professionals on PP3M compared with PP1M. MATERIAL AND METHODS This was a multicenter, retrospective, non-interventional one-time questionnaire survey among patients with psychotic disorders who switched from PP1M to PP3M (n = 38), their relatives (n = 13) and mental health professionals (n = 38). General satisfaction and (un)desired effects were measured using the Medication Satisfaction Questionnaire (MSQ) and the Subjects' Reaction to Antipsychotics (SRA), respectively. Additional questionnaires assessed socio-demographic variables, preference, effectiveness, side-effects, and confidence in PP3M compared to PP1M. RESULTS Mean number of received PP3M injections was 4.2 (SD 2.5). The three study groups reported a high level of confidence in PP3M. High general satisfaction rates about PP3M among patients (69%) and mental health professionals (95%) were reported. The majority of patients, relatives, and mental health professionals reported similar or in some cases even greater effectiveness and similar or in some cases even less side-effects of PP3M compared to PP1M. Sixty-seven percent of the relatives reported less concerns about non-adherence after switching to PP3M. CONCLUSION Most patients, relatives, and mental health professionals prefer PP3M over PP1M. The positive attitudes of all parties may facilitate the more frequent use of PP3M and potentially the clinical outcomes.

Abstract
PURPOSE This retrospective cohort study evaluated real-world data on relapses in adult patients with schizophrenia who transitioned to long-acting injectable paliperidone palmitate once-every-3-months (PP3M) following treatment with once-monthly paliperidone palmitate (PP1M). PATIENTS AND METHODS Data derived from the IBM® MarketScan® Multi-State Medicaid Database were analyzed. Adults aged ≥18 years with ≥1 schizophrenia diagnosis claim and ≥12 months of continuous medical and prescription enrollment before and/or at index date of PP3M were eligible for inclusion. Patients were matched on propensity score to 2 PP3M cohorts: (1) adequately treated (AT), defined as patients treated with PP1M for ≥4 months, with the last 2 doses the same and a PP3M initiation dose meeting the corresponding PP1M-to-PP3M dose conversion, or (2) not adequately treated (NAT), defined as patients who received ≤2 or no PP1M doses. Relapse rates and time to relapse distributions based on the first occurrence of a qualifying event during the 2-year follow-up period were compared between PP3M cohorts using Kaplan-Meier survival curves and log rank test statistics. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards models. Two sensitivity analyses using different matched populations were performed to assess the robustness of the primary findings. RESULTS Propensity score matching yielded a sample of 1314 patients (657 per group). Most patients were male (68.9%) and aged 25-64 years (90.1%). The relapse rate was significantly lower in the AT (18.4%) versus NAT cohort (26.8%), P = 0.0002. Risk of relapse decreased by 35% for AT versus NAT (HR: 0.65 [95% CI: 0.51-0.81]). Relapse reductions favored the AT cohort in both sensitivity analyses (HR: 0.67 [95% CI: 0.54-0.83] and HR: 0.74 [95% CI: 0.56-0.97]). CONCLUSION In this analysis of Medicaid claims data, patients adequately treated with PP1M before transitioning to PP3M demonstrated significantly lower relapse rates and delayed time to relapse.

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
OBJECTIVE This study investigates (1) the proportion of people with psychosis who are on long-acting injectable antipsychotics; (2) the difference in the demographic, clinical, substance use and adverse drug reaction profiles of people taking long-acting injectables compared to oral antipsychotics; and (3) the differences in the same profiles of those on first-generation antipsychotic versus second-generation antipsychotic long-acting injectables. METHODS Data were collected as part of the Survey of High Impact Psychosis. For this study, participants with diagnoses of schizophrenia or schizoaffective disorder who were on any antipsychotic medication were included (N = 1049). RESULTS Nearly a third (31.5%) of people with psychosis were on long-acting injectables, of whom 49.7% were on first-generation antipsychotic long-acting injectables and 47.9% were on second-generation antipsychotic long-acting injectables. This contrasts with oral antipsychotics where there was a higher utilisation of second-generation antipsychotics (86.3%). Of note, compared to those on the oral formulation, people on long-acting injectables were almost four times more likely to be under a community treatment order. Furthermore, people on long-acting injectables were more likely to have a longer duration of illness, reduced degree of insight, increased cognitive impairment as well as poor personal and social functioning. They also reported more adverse drug reactions. Compared to those on first-generation antipsychotic long-acting injectables, people on SGA long-acting injectables were younger and had had a shorter duration of illness. They were also more likely to experience dizziness and increased weight, but less likely to experience muscle stiffness or tenseness. CONCLUSION Long-acting injectable use in Australia is associated with higher rates of community treatment order use, as well as poorer insight, personal and social performance, and greater cognitive impairment. While long-acting injectables may have the potential to improve the prognosis of people with psychosis, a better understanding of the choices behind the utilisation of long-acting injectable treatment in Australia is urgently needed.

Abstract
BACKGROUND To understand the implications of switching from paliperidone palmitate 1-monthly (PP1M) to paliperidone palmitate 3-monthly (PP3M) treatment of schizophrenia from the perspective of four key stakeholders: patients, physicians, nurses and carers. METHODS This was a cross-sectional, retrospective, non-interventional study comprising a one-time questionnaire (PINC-Q) for adult patients (aged ≥18 years) with schizophrenia (International Classification of Diseases; ICD-10) and their physician, nurse and carer. Questionnaires were developed in association with patient and carer advocacy groups (GAMIAN and EUFAMI) and following an advisory board formed of psychiatrists and nurses. The degree of alignment between stakeholders was also examined. RESULTS Responses were received from a total of 224 evaluable patients. For most patients (88.4%), responses were received from at least two other stakeholders. Patients were moderately ill with mild-to-moderate lack of insight and had received PP1M for a mean (standard deviation [SD]) of 23.9 (21.28) months before switching to PP3M (duration mean [SD] 12.8 [3.72] months). The most frequently reported reasons to switch from PP1M to PP3M were 'to live life as normally as possible' and 'patient convenience'. Over 79% of responses within each stakeholder group stated that PP3M helped the patients, with increased patient activity and social involvement, improved frequency and quality of physician-patient and nurse-patient communication and decreased perceived stigma. CONCLUSIONS The results of this study add to the increasing body of evidence supporting the benefits of PP3M in a population of patients with schizophrenia representative of real-world clinical practice.

Abstract
Paliperidone palmitate every three months (PP3M) is expected to facilitate patient's treatment compliance and satisfaction. The objective here was to compare PP3M treatment compliance and satisfaction, effectiveness and tolerability, with paliperidone palmitate-monthly (PP1M) in patients with severe schizophrenia. A 24-month prospective, open-label study of patients with severe schizophrenia treated with PP3M after at least 2 years of stabilization with PP1M (n = 84) was carried out. Treatment satisfaction was assessed with the Treatment Satisfaction Questionnaire for Medication (TSQM) and with a Visual Analogue Scale (VAS). Effectiveness was measured with psychiatric hospital admissions and the Clinical Global Impression-Severity (CGI-S) scale. Tolerability assessments included laboratory tests, weight and adverse effects. Reasons for treatment discontinuation were recorded. CGI-S significantly improved after 24 months. Three patients changed back to PP1M due to adverse effects, and four were hospitalized. There were neither abandoning nor significant changes in weight or biological parameters, and lower incidence of side effects, with PP3M treatment. TSQM and VAS scales increased. No differences were found related to doses. Apart from somewhat improvement in treatment adherence, effectiveness, and tolerability, patients with severe schizophrenia lengthy treated with PP1M showed more satisfaction with PP3M, even those who needed high doses to get clinical stabilization.

Effect of Paliperidone Palmitate 3-Month Formulation on Goal Attainment and Disability After 52 Weeks' Treatment in Patients with Clinically Stable Schizophrenia. Neuropsychiatr Dis Treat 2020; 16:3197-3208. [PMID: 33380797 PMCID: PMC7767727 DOI: 10.2147/ndt.s286654] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2020] [Accepted: 12/08/2020] [Indexed: 01/09/2023] Open
Abstract
PURPOSE This pragmatic clinical study aimed to assess goal attainment among patients with schizophrenia treated with paliperidone palmitate 3-monthly (PP3M) and its relation to their level of disability, and whether patients achieved symptomatic remission at the study endpoint. PATIENTS AND METHODS Goal attainment was assessed as a secondary endpoint using Goal Attainment Scaling (GAS) within a 52-week, prospective, single-arm, non-randomized, open-label, international, multicenter study evaluating the impact of transitioning stable patients with schizophrenia from paliperidone palmitate 1-monthly (PP1M) to PP3M. Additional exploratory analyses were performed to investigate the relationship between disability and functioning as measured by the World Health Organization Disability Assessment Schedule (WHODAS), Version 2.0, symptomatic remission, and goal attainment. RESULTS Overall, 305 patients were enrolled, of whom 281 (92.1%) provided GAS data at baseline. Of these, 160 achieved symptomatic remission at the last observation carried forward (LOCF) endpoint. The most common category of goals was "self" related, of which work-related was most frequent. Two-thirds of patients (67.7%) achieved at least one goal at the LOCF endpoint. Goal achievement was positively associated with lower baseline symptoms and symptomatic remission at LOCF endpoint, and with lower WHODAS scores at baseline and LOCF endpoint and greater WHODAS score improvements from baseline. Age, duration of disease, and duration of PP1M treatment before the switch did not impact goal setting and goal attainment. The proportion of patients with remunerated work status increased by 11.3% at LOCF endpoint. CONCLUSION The results of this secondary endpoint analysis indicate that continued treatment of patients with schizophrenia with PP3M following stabilization with PP1M may facilitate attainment of patients' personal goals and reduce disability, especially, but not exclusively, in patients with symptomatic remission achieved at LOCF.

Abstract
This article discusses case reports of treatment with paliperidone palmitate in comparison with data from recent publications. Second-generation long-acting injectable antipsychotics have been shown to provide better control of psychiatric manifestations, reduce the severity of negative symptoms, improve social functioning and quality of life of patients and relatives, and reduce the burden of disease for both the healthcare system and the caregivers. The case reports presented in this article demonstrate better quality of remission in schizophrenia patients treated with one- monthly and three-monthly paliperidone palmitate formulations, due to higher effi in preventing relapses, better safety and good tolerability regardless of patient age.

Abstract
Introduction There are several new and emerging antipsychotic medication strategies recently marketed or under clinical development for the treatment of several mental disorders. There is the need to provide an up-to-date overview on the safety of this new generation of antipsychotic medications, which includes also the third-generation antipsychotics (TGA). Areas covered The authors aimed at providing a synthesis of the most current evidence about the safety profile of the recently developed and/or marketed antipsychotics. Qualitative synthesis followed an electronic search made inquiring of the following databases: MEDLINE, Embase, PsycINFO, and the Cochrane Library from inception until March 2020, combining free terms and MESH headings for the topics of TGA and recently developed and/or marketed antipsychotics as following: ((safety OR adverse events OR side effects) AND ((brexpiprazole OR cariprazine OR inhaled loxapine OR lumateperone (ITI-007) OR lurasidone OR pimavanserin OR roluperidone (MIN-101) OR transdermal patch asenapine)). Expert opinion Overall, newer antipsychotics display a good safety profile, with a well-demonstrated lower metabolic liability compared to second-generation antipsychotics. Furthermore, TGA appear to specifically target negative symptomatology and improving cognitive domains.

Abstract
BACKGROUND Paliperidone palmitate 3-monthly (PP3M) is a second-generation, long-acting injectable antipsychotic formulation indicated for the maintenance treatment of adults with schizophrenia first stabilized with paliperidone palmitate 1-monthly (PP1M). This exploratory post hoc subgroup analysis of the 52-week, phase 3b REMISSIO study analysed outcomes according to patient age and disease duration in a naturalistic clinical setting. METHODS Outcomes of patients with schizophrenia were analysed according to age [<35 years (n = 123) versus ⩾35 years (n = 182)] and disease duration [⩽3 years (n = 72) versus >3 years (n = 233)]. The primary efficacy outcome was the proportion of patients achieving symptomatic remission according to the Andreasen criteria. Adverse events were monitored throughout the study. RESULTS At endpoint (last observation carried forward), 60.7% (95% CI: 51.4%, 69.4%) of younger patients and 54.1% of older patients (95% CI: 46.6%, 61.6%) achieved symptomatic remission. The proportions for patients with disease duration ⩽3 years and >3 years were similar: 57.8% (45.4%, 69.4%) versus 56.5% (49.8%, 62.9%). Functional remission was reached by 45.4% (36.2%, 54.8%) of patients aged <35 years and 36% (28.9%, 43.6%) of patients aged ⩾35 years with a similar pattern when analysed by disease duration. PP3M had a favourable safety profile and was generally well tolerated in both age groups. CONCLUSION Patients with schizophrenia, previously stabilized on PP1M, may benefit from PP3M treatment with some additional potential improvements if started early in the disease course.

Abstract
OBJECTIVE Paliperidone, a second-generation antipsychotic, has been found to have minimal hepatotoxicity in patients with schizophrenia. However, long-term hepatic outcome in patients with schizophrenia and viral hepatitis remains unclear. METHODS Data obtained from the Taiwan National Health Insurance Research Database was used to enroll newly diagnosed schizophrenic patients between January 2007 and December 2013. Patients with schizophrenia and viral hepatitis who were receiving paliperidone were allocated to the paliperidone group while those who were not receiving paliperidone were allocated to the control group. Using a 1:2 ratio, we matched the age, sex, and index year to select the control participants. Patients with severe hepatic outcomes (SHOs) before enrollment were excluded. The two groups were studied until December 31, 2013. The primary endpoint was the occurrence of SHOs including liver failure, liver decompensation, liver transplantation, or liver cancer. RESULTS We identified 134 patients with schizophrenia and viral hepatitis who received paliperidone and 268 matched patients who did not receive paliperidone. Of the 402 patients, 22 (5.47%) developed SHOs during a mean follow-up period of 3.57 ± 1.62 years, including 2 (1.49%) from the paliperidone cohort and 20 (7.46%) from the control group. Furthermore, the Cox multivariate proportional hazards analysis revealed that the risk decreased with paliperidone use (adjusted hazard ratio [HR]: 0.155, 95% confidence interval [CI]: 0.032-0.737, p = 0.019) after adjusted for confounding factors. CONCLUSION Paliperidone treatment was associated with a reduced risk of SHOs in patients with schizophrenia and viral hepatitis.

Abstract
Schizophrenia remains one of the most severe medical diseases. Current dopamine modulating first-generation and second-generation antipsychotics target mainly positive symptoms, but not/inadequately negative and cognitive symptoms. Additional challenges include non-adherence and adverse effects, especially cardiometabolic dysregulation. This review evaluates new/emerging pharmacological treatments for schizophrenia. Therapies targeting total symptoms include cannabidiol, D3 antagonist/5-HT1A partial agonist F17464, lumateperone (ITI-007), phosphodiesterase 10A (PDE10A) inhibitors MK-8189 and TAK-063, sodium nitroprusside, and trace amine-associated receptor-1 (TAAR1) agonist RO5263397 and SEP-363856. Treatments targeting negative symptoms include the PDE10A inhibitor LuAF-11167, 5-HT2A inverse agonist pimavanserin, sigma-2/5-HT2A antagonist roluperidone (MIN-101), and d-amino acid oxidase (DAAO) inhibitor TAK-831. Agents targeting primarily cognitive dysfunction are the glycine transporter-1 inhibitor BI-425809 and cannabidiol. Therapies targeting residual positive symptoms/treatment-resistant schizophrenia include pimavanserin, dopamine D1/D2 antagonist LuAF-35700, and DAAO inhibitor sodium benzoate. Two new long-acting injectable antipsychotic formulations, Aripiprazole Lauroxil NanoCrystal® and the first subcutaneous injectable LAI Perseris (RBP-7000), were recently approved by U.S. Food and Drug Administration, and positive results were announced for Risperidone ISM®, each achieving therapeutic levels within 24 hours, without need for initial oral cotreatment/loading injection-strategies. Paliperidone palmitate 6-monthly intramuscularly injectable and Risperidone subcutaneously injectable TV46000 are currently under investigation. Finally, the samidorphan+olanzapine combination targets reduced weight gain liability, while maintaining olanzapine's efficacy. Most of these trial programs are still ongoing or have yielded mixed or even negative results. Thus, additional mechanisms of action and agents require study to improve schizophrenia outcomes for total/positive symptoms with reduced adverse effects, but also cognitive symptoms, negative symptoms, and treatment resistance, the areas of greatest need in schizophrenia currently.

Neuropsychiatr Dis Treat 2019; 15:2639-2646. [PMID: 31686823 PMCID: PMC6751763 DOI: 10.2147/ndt.s207910] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/07/2019] [Accepted: 08/12/2019] [Indexed: 12/21/2022] Open
Abstract
OBJECTIVE Schizophrenia clinical trials commonly measure observed changes in Positive and Negative Syndrome Scale (PANSS) total score. However, it is more intuitive to think of response vs nonresponse, a binary outcome. Assessing binary outcomes enables calculation of number needed to treat (NNT) for therapeutic outcomes, number needed to harm (NNH) for adverse outcomes, and likelihood to be helped or harmed (LHH) to demonstrate benefit/risk tradeoffs. Here, NNT, NNH, and LHH were used to evaluate the clinical usefulness of aripiprazole lauroxil in patients with an acute schizophrenia exacerbation. METHODS Categorical efficacy and tolerability data were taken from the pivotal Phase 3 trial evaluating aripiprazole lauroxil for treatment of an acute exacerbation of schizophrenia. NNT and NNH values, with 95% CIs, were calculated in this post hoc analysis. RESULTS Using the intent-to-treat population for the pooled doses of aripiprazole lauroxil (441 mg [n=196] and 882 mg [n=204] q4w), responder rates (≥30% improvement from baseline PANSS total score) were 35.3% for aripiprazole lauroxil arms vs 18.4% for placebo (n=196), yielding a NNT of 6 (95% CI: 5-11). Discontinuation rates due to adverse events (AEs) were higher among patients randomized to placebo than to either aripiprazole lauroxil dose. Akathisia was the only AE with an incidence ≥5% in each aripiprazole lauroxil group and at least twice that of placebo (11.6%, 11.5%, and 4.3% of the patients receiving aripiprazole lauroxil 441 mg, 882 mg, and placebo, respectively), producing a NNH of 14 (95% CI: 9-33) for pooled aripiprazole lauroxil doses vs placebo. Calculating LHH for therapeutic response vs akathisia, aripiprazole lauroxil was 2.3 times more likely to result in a therapeutic response than an incident of akathisia. CONCLUSION Using metrics of NNT, NNH, and LHH, aripiprazole lauroxil was an efficacious and well-tolerated intervention in a pivotal study in patients with an acute schizophrenia exacerbation.
