Abstract
INTRODUCTION Hair loss is driven by multiple factors, including genetics. Androgenetic alopecia (AGA) is a condition in which treatments necessitate prolonged compliance with prescribed medications. We have developed IVL3001, a long-acting injectable (LAI) formulation of finasteride encapsulated within poly lactic-co-glycolic acid microspheres, to enhance the efficacy of the finasteride and to achieve consistent positive outcomes in adults. An open-label, sequential, single-dose phase I clinical trial was designed to evaluate the safety, pharmacokinetic (PK), and pharmacodynamic (PD) of IVL3001. METHODS A total of 40 non-smoking, healthy adult males were divided into three cohorts where the IVL3001 group received a single subcutaneous injection of 12-36 mg IVL3001 and 1 mg finasteride (Propecia®) once daily for 28 days. The plasma concentrations of finasteride, dihydrotestosterone (DHT), and testosterone were measured using liquid chromatography-tandem mass spectrometry. The tolerability of the injections was assessed, and compartment models were developed to predict the effective dose and assess PK/PD profiles. RESULTS IVL3001 and finasteride 1 mg tablets were well tolerated. IVL3001 showed consistent plasma concentrations without bursts or fluctuations. Consistent with its mechanism of action, IVL3001 reduced DHT levels. Simulation data showed that the administration of 12-36 mg of IVL3001 every 4 weeks achieved plasma concentrations similar to finasteride, with comparable DHT reduction. CONCLUSION The present study represents the first clinical trial to evaluate the safety, pharmacokinetic (PK), pharmacodynamic (PD), and tolerability of finasteride long-acting injectables (LAI) in adults. The rapid onset of action sustained effective drug concentration and the prolonged half-life of IVL3001 suggest that it offers multiple benefits over conventional oral formulations in terms of therapeutic response and compliance. TRIAL REGISTRATION ClinicalTrials.gov identifier, NCT04945226.

Abstract
BACKGROUND We compared the effectiveness of long-acting injectable antipsychotics (LAIs) and oral antipsychotics (OAs) in treating schizophrenia, focusing on whether the benefits of LAIs over OAs are evident even in the prevalent new user design and on effect heterogeneity. METHODS We conducted a prevalent new user cohort study using 2 administrative claims databases in Japan. We included patients with schizophrenia initiated on LAIs and propensity score-matched patients on OA. We compared the risks of psychiatric hospitalization and treatment discontinuation based on hazard ratios (HRs) using the Cox proportional hazards model. Effect heterogeneity was evaluated using subgroup analyses. RESULTS In total, 2520 patients using LAI and OA were identified as matched cohorts. Long-acting injectable antipsychotics were associated with a higher psychiatric hospitalization risk than OAs (HR, 1.41; 95% confidence interval [CI], 1.06-1.88) in the entire population; however, LAIs were associated with lower risk in the group with a low proportion of days covered and psychiatric hospitalization history (HR, 0.51; 95% CI, 0.30-0.89). Long-acting injectable antipsychotics were associated with a lower risk of treatment discontinuation than OAs (HR, 0.76; 95% CI, 0.66-0.87) in the entire population; in the subgroup analyses, a consistent trend was observed in all strata (LAIs had a lower risk). CONCLUSIONS Using a prevalent new user design, this study confirmed that LAIs have an advantage regarding treatment continuity. Long-acting injectable antipsychotics had higher psychiatric hospitalization risk than OAs in the entire population; however, this study suggested the presence of effect heterogeneity due to psychiatric hospitalization history.

Abstract
Data on the use of long-acting injectable antipsychotics (LAIs) in rural community mental healthcare settings are scarce. This study aimed to investigate the prescription patterns of LAIs in a clinical sample of patients with schizophrenia-spectrum disorders in rural Greece. All patients with schizophrenia-spectrum disorders who regularly attend the Mobile Mental Health Unit of the prefectures of Ioannina and Thesprotia (MMHU I-T) in northwestern Greece were included in the study. The sample consists of 87 patients (59 males and 28 females) with a mean age of 54.4 years and a mean illness duration of 28 years. Most patients (72.4%) received antipsychotic monotherapy, and nearly 30% received an LAI formulation, mostly a second-generation LAI (20 of 26 patients, 76.9%). The treatment regimen comprised benzodiazepines in one-third of the patients and antidepressants in one-quarter. There was no statistically significant association between treatment regimen and the clinical and demographic variables studied, except for biological sex (female). The percentage of patients treated with LAIs in this study was almost three times higher than the rate previously reported in Greece and is higher than the rates reported in other countries. Patients with schizophrenia-spectrum disorders in rural Greece may have adequate access to innovative treatment with second-generation LAIs. Further research is needed to demonstrate the cost-effectiveness of LAI treatment in rural communities and to elucidate the factors associated with such treatment.

Abstract
INTRODUCTION Maintenance antipsychotic treatment improves multiple outcomes in people with schizophrenia. These benefits are challenged by medication nonadherence, which is a common occurrence. Long-acting injectable antipsychotic (LAI) formulations were developed to reduce nonadherence and thereby improve outcomes. This narrative review is based on a PubMed search (January 2000 - August 2022) for studies on LAI antipsychotics. AREAS COVERED Opportunities and challenges associated with LAIs are reviewed. Advantages, compared to oral antipsychotics (OAs), include improved adherence, reduced relapse and hospitalization risk, delayed and lower relapse risk after stopping treatment, and the ability to differentiate true treatment resistance from 'pseudo'-resistance. Additionally, LAIs are associated with lower all-cause mortality than OAs. LAIs are under-used in many services, partly reflecting negative attitudes, misconceptions, and lack of knowledge among clinicians, patients, and carers. Practical barriers to LAI use include acquisition costs and inadequate service structures to administer/monitor LAI treatment. EXPERT OPINION The education and engagement of clinicians, patients and caregivers can assist more informed decision-making regarding LAIs. Future research regarding LAIs should encompass multiple complementary designs, focus on functionality and recovery outcomes, and include groups at high risk of relapse, including those with comorbid substance use disorders and early in the course of schizophrenia.

Abstract
BACKGROUND Long-acting antipsychotics (e.g. 1-monthly (PP1M) / 3-monthly (PP3M) injection forms of paliperidone palmitate) have been developed to improve treatment continuation in schizophrenia patients. We aim to assess risk factors of treatment discontinuation of patients on paliperidone palmitate and risperidone microsphere. Additionally, treatment discontinuation between patients with PP1M and PP3M was compared. METHODS The IQVIA Longitudinal Prescription databases were used. Risk factors of treatment discontinuation were identified by a multilevel survival regression using Cox proportional hazards model. Kaplan Meier analyses were performed by identified significant risk factors. RESULTS Twenty-five thousand three hundred sixty-one patients (France: 9,720; Germany: 14,461; Belgium: 1,180) were included. Over a one-year follow-up period, a significant lower treatment discontinuation was observed for patients newly initiated on paliperidone palmitate (53.8%) than those on risperidone microspheres (85.4%). Additionally, a significantly lower treatment discontinuation was found for 'stable' PP3M patients (19.2%) than 'stable' PP1M patients (37.1%). Patients were more likely to discontinue when drugs were prescribed by GP only (HR = 1.68, p < 0.001 vs. psychiatrist only) or if they were female (HR = 1.07, p < 0.001), whereas discontinuation decreased with age (31-50 years: HR = 0.95, p = 0.006 and > 50 years: HR = 0.91, p < 0.001 vs. 18-30 years). CONCLUSIONS This study demonstrates that patients stay significantly longer on treatment when initiated on paliperidone palmitate as compared to risperidone microspheres. It also indicated a higher treatment continuation of PP3M over PP1M. Treatment continuation is likely to be improved by empowering GPs with mental health knowledge and managing patients by a collaborative primary care-mental health model. Further research is needed to understand why females and younger patients have more treatment discontinuation.

Abstract
Pooling studies with different clinical and methodological features may lead to statistical heterogeneity, particularly if heterogeneity remains unexplained. One potential source of heterogeneity may be how much the included trials tend toward a pragmatic or explanatory design. Many tools have been developed to aid researchers in quantifying pragmatism in clinical trials, at both the design and appraisal stages.In this chapter we review these tools, illustrate examples of their use, and discuss methods of including pragmatism in meta-analysis as a way of exploring heterogeneity.We suggest a stepwise approach to incorporating evidence from pragmatic and explanatory trials which includes planning to assess pragmatism at the protocol stage, collecting data on pragmatism, extracting data on treatment effects, incorporating pragmatism in meta-analysis using subgroup analysis or meta-regression techniques, and interpreting and reporting the findings transparently.

Abstract
AIMS Non-compliance is still an important problem in psychotic patients. Although antipsychotic (AP) treatment leads to a decrease in psychotic relapses, there are no clear recommendations about how long treatment should be maintained after first-episode psychosis (FEP) and no indication of the rates and causes of treatment withdrawal in this group. METHODS We evaluated a large sample of patients with FEP for 2 years to compare the time to all-cause treatment discontinuation of AP drugs and the time to the first relapse. We collected the sociodemographic and psychopathological characteristics of the sample. The number of relapses was also recorded. RESULTS A total of 310 FEP patients were assessed across seven early intervention teams (mean age = 30.2 years; SD = 11.2). The most prevalent diagnosis at baseline was psychotic disorder not otherwise specified (36.1%), and the most commonly used APs were risperidone (26.5%) and olanzapine (18.7%). A lack of efficacy was the most frequent reason for the withdrawal of the first AP prescribed, followed by non-compliance. There were no differences in the relapse rates between different APs. Patients treated with long-acting injectable (LAI) APs presented less disengagement from services than patients treated with oral APs. CONCLUSIONS Although there were no differences between the different APs in terms of relapse rates, LAIs had higher retention rates than oral APs in early intervention services. Compliance is still an important issue in Psychiatry, so clinicians should use different strategies to encourage it, such as the use of LAI treatments.

Abstract
Schizophrenia is a serious mental illness that requires continuous and effective long-term management to reduce symptoms, improve quality of life, and prevent relapse. Oral antipsychotic medications have proven efficacy for many patients taking these medications; however, a considerable number of patients continue to experience ongoing symptoms and relapse, often due to lack of adherence. The advent of long-acting injectable (LAI) formulations of antipsychotic medications provided an opportunity to improve treatment adherence and overall patient outcomes. Despite data to support LAI efficacy, safety, and improved adherence over oral formulations, there are several misconceptions about and barriers to LAI implementation within a standard of care for patients with schizophrenia. Areas of resistance around LAIs include (1) doubts regarding their benefits outside of improved adherence, (2) questions regarding their prescribing to a broader population of patients with schizophrenia, (3) when to initiate LAIs, (4) concerns regarding the safety of LAIs in comparison with oral medication, and (5) the most effective ways to educate healthcare providers, patients, and caretakers to enable appropriate LAI consideration and acceptance. Here, we discuss these key controversies associated with LAIs and provide supportive evidence to facilitate LAI use in a manner that is constructive to the clinician-patient relationship and successful treatment.

Abstract
IMPORTANCE Long-acting injectable antipsychotics (LAIs) can potentially reduce hospitalization risk by enhancing medication adherence but are rarely considered for early-phase schizophrenia treatment. OBJECTIVE To determine whether encouraging use of a LAI compared with usual care delays the time to first hospitalization with patients with early-phase illness. DESIGN, SETTING, AND PARTICIPANTS The Prevention of Relapse in Schizophrenia (PRELAPSE) trial was cluster randomized with a follow-up duration of 2 years. The study began in December 2014, was completed in March 2019, and was conducted in 39 mental health centers in 19 US states. Site randomization assigned 19 clinics to encourage treatment with long-acting aripiprazole monohydrate (aripiprazole once monthly [AOM] condition) and 20 to provide treatment as usual (clinician's choice [CC] condition). Participant eligibility criteria included (1) schizophrenia diagnosis confirmed by a structured clinical interview, (2) fewer than 5 years of lifetime antipsychotic use, and (3) age 18 to 35 years. The AOM sites identified 576 potentially eligible participants, of whom 234 (40.6%) enrolled; CC sites identified 685 potentially eligible participants, of whom 255 (37.2%) enrolled. INTERVENTIONS There were no restrictions on treatment at CC sites (including using LAIs) or at AOM sites with the exception that aripiprazole monohydrate had to be prescribed within US Food and Drug Administration-approved guidelines. MAIN OUTCOMES AND MEASURES The primary outcome was time to first psychiatric hospitalization based on participant interviews every 2 months, the service use resource form administered every 4 months, and other sources (eg, health records) as available. Potential events were adjudicated by an independent committee masked to treatment assignment. RESULTS The 489 participants (368 men [75.3%]) had a mean (SD) age of 25.2 (4.2) years and 225 (46.0%) had 1 year or less lifetime antipsychotic use. Fifty-two AOM (22%) and 91 CC participants (36%) had at least 1 hospitalization. The mean survival time until first hospitalization was 613.7 days (95% CI, 582.3-645.1 days) for AOM participants and 530.6 days (95% CI, 497.3-563.9 days) for CC participants. For time to first hospitalization, the hazard ratio was 0.56 (95% CI, 0.34- 0.92; P = .02), favoring AOM. Survival probabilities were 0.73 (95% CI, 0.65-0.83) for AOM participants and 0.58 (95% CI, 0.50-0.67) for CC participants. The number needed to treat to prevent 1 additional hospitalization was 7 participants treated with AOM compared with CC. CONCLUSIONS AND RELEVANCE Long-acting injectable antipsychotic use by patients with early-phase schizophrenia can significantly delay time to hospitalization, a personally and economically important outcome. Clinicians should more broadly consider LAI treatment for patients with early-phase illness. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT02360319.

Bahji A, Carlone D, Altomare J. Acceptability and efficacy of naltrexone for criminal justice-involved individuals with opioid use disorder: a systematic review and meta-analysis. Addiction 2020; 115:1413-1425. [PMID: 31863669 DOI: 10.1111/add.14946] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2019] [Revised: 10/31/2019] [Accepted: 12/16/2019] [Indexed: 01/04/2023]
Abstract
BACKGROUND AND AIMS Criminal justice-involved individuals carry a disproportionately higher burden of opioid use disorder (OUD) than those not involved with the criminal justice system, and are often unable to access opioid agonist therapies such as methadone and buprenorphine. The opioid receptor antagonist naltrexone (NTX) is effective for the prevention of relapse to OUD and may be more acceptable in criminal justice settings. The objectives of this review were to: (1) provide an overall summary effect across studies for the efficacy and acceptability of oral and injectable NTX for the treatment of OUD among criminal justice-involved individuals and (2) examine systematic variations in study results to explain heterogeneity among study-specific effects. METHODS Systematic review and meta-analysis of 1045 patients across 11 studies (10 randomized controlled trials, one quasi-experimental study). All available outcomes were pooled using random-effects meta-analysis. Subgroup analyses were conducted for oral and injectable naltrexone; meta-regression analyses were conducted for socio-demographic and study-level characteristics. RESULTS NTX improved retention in treatment [risk ratio (RR) = 1.31; 95% confidence interval (CI) = 1.05, 1.63], reduced rates of re-incarceration (RR = 0.70, 95% CI = 0.54-0.92), reduced opioid relapse (RR = 0.63, 95% CI = 0.53-0.76) and improved opioid abstinence (RR = 1.38, 95% CI = 1.16-1.65). While NTX was associated with a greater burden of adverse events overall (RR = 1.49, 95% CI = 1.13-1.95), the findings were inconclusive as to whether or not a difference was present for the number of serious adverse events or overdoses. CONCLUSIONS Naltrexone appears to be efficacious and acceptable for the treatment of opioid use disorder among criminal justice-involved individuals; however, the risk for adverse events must be weighed against the potential benefits.

Effect of paliperidone palmitate on hospitalisation in a naturalistic cohort – a four-year mirror image study. Eur Psychiatry 2020; 37:43-8. [DOI: 10.1016/j.eurpsy.2016.04.009] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/01/2016] [Revised: 04/12/2016] [Accepted: 04/16/2016] [Indexed: 11/20/2022] Open
Abstract
AbstractBackgroundClinical trial outcomes are heavily influenced by the non-naturalistic clinical trial process. Observations of outcomes in clinical practice are a valuable adjunct to clinical trial results.HypothesisOur null hypothesis was that clinically indicated switching to paliperidone palmitate had no effect on hospital admissions or hospital bed days.MethodThis was a part-prospective mirror image study examining outcomes 2 years before starting paliperidone palmitate and 2 years after. Sensitivity analyses examined the effect of different placings of the mirror in the mirror image design.ResultsWe prospectively followed-up 225 patients prescribed paliperidone palmitate in clinical practice. At 2 years, 41.8% of patients were still receiving paliperidone palmitate. In the primary analysis, the mean number of admissions fell from 1.80 in the two years before starting paliperidone palmitate to 0.81 in two years following the drug’s initiation (outpatients) or two years following hospital discharge (inpatients) (P < 0.001). More than half of patients were not admitted to hospital during two years follow-up. Mean total bed days was reduced from 79.6 in the two years before to 46.2 in the two years after paliperidone palmitate initiation or discharge (P < 0.001). Sensitivity analyses gave broadly similar outcomes. Continuers demonstrated better outcomes than discontinuers in sensitivity analyses but not in the primary analysis.ConclusionPaliperidone palmitate initiation is associated with a substantial reduction in hospital admissions and days spent in hospital. The reduction in costs associated with reduced use of health care facilities is likely to exceed the purchase and administration costs of the drug.

Comparative effectiveness of second generation long-acting injectable antipsychotics based on nationwide database research in Hungary. PLoS One 2019; 14:e0218071. [PMID: 31194778 PMCID: PMC6563992 DOI: 10.1371/journal.pone.0218071] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2018] [Accepted: 05/25/2019] [Indexed: 01/14/2023] Open
Abstract
Background Schizophrenia is a severe condition that affects approximately 1% of the population. Certain elements of antipsychotic treatment can only be examined in large population, thus the need for population-based real-world analyses has been increasing. Patients and methods Hungarian National Health Fund database includes all healthcare data of the population of Hungary. All patients diagnosed with schizophrenia between 01.01.2006 and 31.12.2015 were included in the study. We analyzed all patients with newly initiated second-generation antipsychotic during the inclusion period (01.01.2012–31.12.2013). Patients were followed for 2 years. All-cause treatment discontinuation served as the primary outcome of the study. Patients with newly initiated long-acting injectable treatments were further investigated in stratified analyses based on their previous treatment. Results 106,624 patients had schizophrenia diagnosis during the study period. 12,232 patients met the inclusion criteria for newly initiating second-generation antipsychotic during the inclusion period. The proportion of patients still on treatment after 1 year for oral treatments varied between 17% (oral risperidone) and 31% (oral olanzapine) while the analogous data for long acting injectables were between 32% (risperidone long acting) and 64% (paliperidone long acting one monthly). The 2-year data were similarly in favor of long-actings. Median time to discontinuation in the oral group varied between 57 days (clozapine) and 121 days (olanzapine). The median time to discontinuation for long-actings was significantly longer: between 176 and 287 days; in case of paliperidone long acting, median was not reached during the observation period. Patients receiving long-acting treatment switched from another long-acting remained on the newly initiated treatment significantly longer than those switched from orals. Conclusion Our results indicate the superiority of second generation long-acting antipsychotics with regard to rates of treatment discontinuation and periods of persistence to the assigned medication.

Abstract
PURPOSE Long-acting injectable (LAI) antipsychotic paliperidone palmitate 3-month formulation (PP3M) is indicated in the United States for the treatment of schizophrenia only after adequate treatment with paliperidone palmitate 1-month formulation (PP1M) for ≥4 months. This analysis aimed to identify patient and disease characteristics during PP1M treatment associated with greater likelihood of achieving remission after transition to PP3M. METHODS A post hoc analysis of a randomized, Phase III, double-blind, noninferiority trial of PP3M vs PP1M (ClinicalTrials.gov identifier: NCT01515423) was conducted in adult patients with schizophrenia. Patients achieving clinical stability after 17 weeks of open-label PP1M were randomized to 48 weeks of double-blind treatment with PP3M or PP1M. The primary objective of this exploratory post hoc analysis was to identify demographic and/or clinical variables associated with persistent remission after treatment with PP3M. Multiple logistic regression analysis identified the following significant predictors of remission: Positive and Negative Syndrome Scale (PANSS) Marder negative symptom factor score, Clinical Global Impression-Severity (CGI-S) total score, and Personal and Social Performance (PSP) total score. RESULTS At double-blind baseline, a 1-point reduction in Marder negative symptom factor score was associated with a 20% increase in the odds of achieving remission after PP3M treatment; 1-point reduction in CGI-S was associated with a doubling in remission odds; and 7- and 10-point improvements in PSP scores, respectively, were associated with 42% and 65% increases in remission odds. CONCLUSION Patients with early clinically meaningful improvements in disease symptoms and severity while establishing stable PP1M dosage are more likely to achieve remission after transition to PP3M.

Abstract
OBJECTIVE Investigate the associations of long-acting injectable (LAI) second generation antipsychotic drugs with number of relapses, psychiatric admissions, days hospitalized, intentional self-harm events, and costs linked to hospitalizations in incident patients diagnosed with schizophrenia. METHOD A nationwide, population-based, retrospective study utilizing mirror-image models before and after initiation of LAI SGA. RESULTS 10,509 patients were included as study population, with analyses being conducted on 2223 patients in a six-month period, 1383 in a 12-month period, 713 in a 24-month period. After initiation of LAI antipsychotics, patients experienced a reduction in number of relapses with an incidence rate ratio (IRR) of 0.60 for the first six months, IRR 0.64 for the first 12 months and IRR 0.64 for the first 24 months following initiation of LAI, all P < 0.001. The number of psychiatric admissions was reduced in a similar manner with respective IRR of 0.59, 0.60 and 0.64, all P < 0.001. Psychiatric bed-days were reduced with 58, 100 and 164 days for the respective periods after LAI initiation, all P < 0.001. In a Cox regression model in patients initiated on LAI, higher age at diagnosis, hazard rate ratio (HR) 0.99, 95%CI(0.98-0.99), P < 0.001, and a later calendar year of diagnosis, HR 0.99, 95%CI(0.98-1.00), P < 0.05, were associated with a lower risk of relapse, whereas mainly psychiatric comorbidity, HR 1.07, 95% CI (1.04-1.11), P < 0.001, and cardiovascular disease, HR 1.12, 95%CI(1.01-1.26), P < 0.05, were associated with relapse. CONCLUSION Even though the design does not allow inferences regarding causality, these population-based findings support the use of second generation LAI antipsychotics.

Abstract
ABSTRACT Poor adherence to antipsychotics, which affects outcome, is frequent in first episode psychosis (FEP). Most randomized studies demonstrate no superiority of long-acting injectable antipsychotics (LAI-AP) over oral antipsychotics (OAP). However, participants in these studies represent a minority of patients who may benefit from LAI-AP. Mirror and naturalistic studies generally demonstrate efficacy of LAI-AP on more representative samples, but studies on FEP are scarce. AIM To describe LAI-AP's utilization and impact on FEP outcome in a naturalistic setting. METHODS A 3-year longitudinal prospective and retrospective descriptive study of all consecutive admissions from two Early Intervention Services for psychosis (EIS) in Montréal, Canada, compared the characteristics and evolution of patients who received LAI-AP for at least 12 months to those who received OAP only. RESULTS From 375 FEP patients included, 26,7% received LAI-AP during their follow-up. They were more likely to have poor prognostic factors (male gender, lower premorbid functioning, homelessness, substance use disorder and schizophrenia spectrum diagnoses). Despite a more severe illness and lower functioning in the LAI-AP group, at admission and study endpoint, clinical and functional improvements were observed. CONCLUSION Early prescription of LAI-AP seems beneficial in FEP with poor prognostic factors.

Abstract
Compared with oral antipsychotics (OAPs), long-acting injectable antipsychotics (LAIs) should improve medication adherence and reduce relapses in schizophrenia. However, meta-analyses of randomized trials and mirror-image studies yielded inconsistent results. Nonrandomized cohort studies with parallel comparisons of LAIs and OAPs offer a third design to examine this issue. We meta-analyzed cohort studies with ≥24 weeks duration and hospitalization data. Primary outcome was hospitalization rate, ie, number of hospitalizations per person-year. Secondary outcomes included hospitalization risk, ie, proportion of patients experiencing ≥1 hospitalizations, all-cause discontinuation, and total hospitalization days. Patient severity and/or chronicity at baseline was also meta-analyzed and explored as a potential effect size moderator. Altogether, 42 studies (n = 101 624; follow-up = 18.6 ± 10.0 mo) were meta-analyzed. LAIs were superior to OAPs regarding hospitalization rate (studies = 15, person-years = 68 009, rate ratio = 0.85, 95% CI = 0.78-0.93, P < .001) and all-cause discontinuations (studies = 10, n = 37 293, risk ratio = 0.78, 95% CI = 0.67-0.91, P = .001), but not regarding hospitalization risk (studies = 33, n = 51 733, risk ratio = 0.92, 95% CI = 0.84-1.00, P = .06), and hospitalization days (studies = 11, n = 21 328, Hedges' g = -0.05, 95% CI = -0.16 to 0.06, P = .39). Illness severity/chronicity was significantly greater in patients prescribed LAIs vs OAPs when all available information was pooled together (studies = 23, n = 61 806, Hedges' g = 0.15, 95% CI = 0.03-0.26, P = .01), but not when examined separately. In summary, this meta-analysis of cohort studies, which included patients that are broadly representative of clinical practice, indicates that LAIs are superior to OAPs. The lack of significant superiority of LAIs for hospitalization risk and hospital days needs to be interpreted in the context of naturalistic treatment selection with subsequently greater illness severity/chronicity in LAI-treated patients.

Abstract
OBJECTIVE The present guidelines address the pharmacotherapy of schizophrenia in adults across different stages, phases, and symptom domains. METHOD Guidelines were developed using the ADAPTE process, which takes advantage of existing guidelines. Six guidelines were identified for adaptation, with recommendations extracted from each. For those specific to the pharmacotherapy of schizophrenia in adults, a working group selected between guidelines and recommendations to create an adapted guideline. RESULTS Recommendations can be categorized into 6 areas that include 1) first-episode schizophrenia, 2) acute exacerbation, 3) relapse prevention and maintenance treatment, 4) treatment-resistant schizophrenia, 5) clozapine-resistant schizophrenia, and 6) specific symptom domains. For each category, recommendations are made based on the available evidence, which is discussed and linked to other established guidelines. CONCLUSIONS In most cases, evidence-based recommendations are made that can be used to guide current clinical treatment and decision making. Notably, however, there is a paucity of established evidence to guide treatment decision making in the case of clozapine-resistant schizophrenia, a subsample that represents a sizable proportion of those with schizophrenia.

Abstract
Long acting injections (LAI) are an effective alternative mode of administration of antipsychotics, less commonly used in clinical practice. Gap in knowledge base is an important source of attitudinal bias. Current article is focused on reviewing the literature for the principles underlying the choice, initiation, maintenance, switch and termination of an LAI; historical, pharmacological and clinical factors implicating the rationale of using LAI against oral agents and older against newer LAIs. Evidences available in clinical and basic psychopharmacological researches are critically appraised, highlighting the lacunae in our understanding. It is endeavored to open the window for the studies to be carried forward in the future answering critical questions which could lay a stronger base for clinical utility of different LAIs. Thus, this article tries to acquaint clinicians with the translatable knowledge imparted from the research and riposte queries for the researchers to explore in relation to LAI.

Abstract
Achieving greater continuation of treatment is a key element to improve treatment outcomes in schizophrenia patients. However, reported treatment continuation can differ markedly depending on the study design. In a retrospective setting, treatment continuation remains overall poor among patients using antipsychotics. This study aimed to document the difference in treatment continuation between four long-acting injectable antipsychotics based on the QuintilesIMS LRx databases, national, longitudinal, panel based prescription databases of retail pharmacies, in the Netherlands and Belgium. Paliperidone palmitate once monthly, risperidone microspheres, haloperidol decanoate, and olanzapine pamoate were studied. This study demonstrated significantly higher treatment continuation of paliperidone palmitate once monthly compared to risperidone microspheres (p-value<0,01) and haloperidol decanoate (p-value<0,01) in both countries, a significantly higher treatment continuation of paliperidone palmitate once monthly compared to olanzapine pamoate in the Netherlands (p-value<0,01), and a general trend towards better treatment continuation versus olanzapine pamoate in Belgium. Analysing the subgroup of patients without previous exposure to long-acting antipsychotic treatment revealed the positive impact of previous exposure on treatment continuation with a subsequent long acting treatment. Additionally, the probability of restarting the index therapy was higher among patients treated with paliperidone palmitate once monthly compared to patients treated with risperidone microspheres and haloperidol decanoate. The data source used and the methodology defined ensured for the first time a comparison of treatment continuation in a non-interventional study design for the four long-acting injectable antipsychotics studied.

Abstract
INTRODUCTION Prevention of relapse is a major challenge in schizophrenia, a disease characterized by poor adherence to antipsychotic medication leading to multiple rehospitalizations and a substantial burden-of-care. METHODS We narratively review published clinical data from the development of long-acting injectable (LAI) formulations of antipsychotic drugs and examine the comparative effectiveness of oral versus LAIs in schizophrenia, with a focus on the second-generation LAI antipsychotic aripiprazole. Evidence is presented from studies with naturalistic/pragmatic as well as explanatory trial designs, supported by the clinical experience of the authors. RESULTS LAI formulations of antipsychotic drugs offer advantages over oral medications and there is good evidence for their use as a first-choice treatment and in younger patients. Key phase III studies have shown aripiprazole once-monthly 400 mg (AOM 400) to be effective and well tolerated, with high rates of adherence and low rates of impending relapse. In a recent randomized trial with a "naturalistic" study design more representative of routine clinical practice, AOM 400 was well tolerated and had significantly greater effectiveness than paliperidone LAI overall and in younger patients aged ≤35 years. CONCLUSION Results across the "full spectrum" of efficacy in traditional clinical trials as well as those encompassing the concept of effectiveness in a more naturalistic setting of real-life clinical practice support the use of AOM 400 as a valid long-term treatment option in schizophrenia overall, as well as earlier in the treatment course, and not solely in situations of poor adherence or when oral antipsychotics have failed.

Clinical trial methodology to assess the efficacy/effectiveness of long-acting antipsychotics: Randomized controlled trials vs naturalistic studies. Psychiatry Res 2017; 247:257-264. [PMID: 27936437 DOI: 10.1016/j.psychres.2016.11.044] [Citation(s) in RCA: 28] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/23/2016] [Revised: 10/26/2016] [Accepted: 11/28/2016] [Indexed: 11/24/2022]
Abstract
Schizophrenia presents unique difficulties in clinical trial design associated with the condition's variable presentation and clinical course, and multiple features influencing affect, cognition, volition and perception. Randomized controlled trials (RCTs) are explanatory studies using a carefully selected patient population, predefined assessment intervals and, generally, symptom-focused endpoints. Naturalistic studies are pragmatic, with no active intervention, and outcomes that are generally those used in clinical practice (e.g. hospitalization, relapse rate). Both naturalistic studies and RCTs have pros and cons, making it difficult for physicians in clinical practice to apply research findings to their own treatment decisions. The choice of clinical trial design can have a significant impact on the comparative effectiveness or efficacy of drugs. This is particularly true for studies comparing long-acting injectable (LAI) antipsychotics with oral antipsychotics in schizophrenia, in which RCTs generally show no benefit for LAIs over oral drugs, whereas observational studies do. The more pragmatic the study design, the more likely it is to show a benefit for LAIs versus oral therapy. This article reviews the pros and cons of different study types, using published examples. Criteria are outlined to help physicians design appropriate prospective studies in schizophrenia including the relevant pragmatic and/or explanatory features, as required.

Soc Psychiatry Psychiatr Epidemiol 2016; 51:1623-1632. [PMID: 27338740 PMCID: PMC5091737 DOI: 10.1007/s00127-016-1259-7] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2016] [Accepted: 06/15/2016] [Indexed: 12/22/2022]
Abstract
PURPOSE The purpose of this study was to investigate the level of adherence to antipsychotic prescription medication in a well-defined homeless cohort over a 15-year period. We hypothesized that adherence would be well below the recommended threshold for clinical effectiveness (80 %), and that it would be strongly associated with modifiable risk factors in the social environment in which homeless people live. METHOD Linked baseline data (including comprehensive population-level administrative prescription records) were examined in a subpopulation of participants from two pragmatic-randomized trials that investigated Housing First for homeless and mentally ill adults. Adherence to antipsychotic medication was operationalized using the medication possession ratio. Multivariable logistic regression was used to estimate effect sizes between socio-demographic, homelessness-related and illness factors, and medication possession ratio. RESULTS Among the 290 participants who met inclusion criteria for the current analysis, adherence to antipsychotic prescription was significantly associated with: history of psychiatric hospitalization; receipt of primary medical services; long-acting injectable antipsychotic formulations; and duration of homelessness. Mean medication possession ratio in the pre-randomization period was 0.41. Socio-demographic characteristics previously correlated with antipsychotic non-adherence were not significantly related to medication possession ratio. CONCLUSIONS This is the first study to quantify the very low level of adherence to antipsychotic medication among homeless people over an extended observation period of 15 years. Each of the four factors found to be significantly associated with adherence presents opportunities for intervention. Strategies to end homelessness for this population may represent the greatest opportunity to improve adherence to antipsychotic medication.

Comparative cost-effectiveness of 11 oral antipsychotics for relapse prevention in schizophrenia within Singapore using effectiveness estimates from a network meta-analysis. Int Clin Psychopharmacol 2016; 31:84-92.

Abstract
This study modelled the cost-effectiveness of 11 oral antipsychotics for relapse prevention among patients with remitted schizophrenia in Singapore. A network meta-analysis determined the relative efficacy and tolerability of 11 oral antipsychotics (amisulpride, aripiprazole, chlorpromazine, haloperidol, olanzapine, paliperidone, quetiapine, risperidone, sulpiride, trifluoperazine and ziprasidone). The clinical estimates were applied in a Markov model to estimate lifetime costs and quality-adjusted life-years gained. Quality-of-life data were obtained from published literature. Resource utilization and cost data were retrieved from local hospital databases. The annual direct cost of healthcare services for a patient experiencing a relapse episode was three-fold that of a patient not in relapse of schizophrenia. The most favourable pharmacological treatment for relapse prevention was olanzapine with an annual probability of relapse of 0.24 (0.13-0.38) with placebo as a reference of 0.75 (0.73-0.78). Olanzapine emerged as the dominant treatment with the highest quality-adjusted life-years gained and lowest lifetime costs. Ziprasidone, aripiprazole and paliperidone incurred higher lifetime costs compared with no treatment. Probability and cost of relapse were key drivers of cost-effectiveness in sensitivity analyses. The data can help prescribers in choosing appropriate treatment and payers in allocating resources for the clinical management of this serious psychiatric disorder.
