Effectiveness and Tolerability of Switching to Aripiprazole Once Monthly from Antipsychotic Polypharmacy and/or Other Long Acting Injectable Antipsychotics for Patients with Schizophrenia in Routine Practice: A Retrospective, Observation Study.

ABSTRACT: Objective:This study was done for collection of real world data of Aripiprazole Once Monthly (AOM) in patients with schizophrenia. Methods:The observation was up to 12 months from the first use of AOM in patients with antipsychotic polypharmacy (APpoly)/other long acting injectable antipsychotics (LAIs) for treatment of schizophrenia in daily practice. Demographics and available clinical information such as The Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression-severity (CGI-S) scores were retrieved from the electronic medical record (EMR). Adverse events were also noted as described in EMR. Results:Eighteen patients were found to be switched from APpoly/LAIs. Mean numbers of previous APs treatment failure and immediate prior APs were 2.2 and 2.4, respectively; most commonly used APs before AOM were aripiprazole, blonanserin, quetiapine, and risperidone. Mean number of combined APs before AOM significantly decreased from 2.4 use to 0.7 at month 12 (p < 0.0001). The PANSS total (71.7 to 62.1, p = 0.000) and CGI-S (3.4 to 3.1, p = 0.008) scores were also significantly decreased from baseline (first use of AOM) to month 12, respectively. Other various psychotropics including anxiolytics were also significantly and substantially decreased at some point from baseline throughout the observation period as well. Mild hand tremor and akathisia were developed in 3 patients. Conclusion:The present observation study clearly confirmed the use of AOM should be also effective and tolerable treatment option for patients with APpoly/LAIs in the real world practice. Subsequent, adequately-powered, and well-controlled clinical trials are warranted in near future.

Project description:ObjectiveIn a number of controlled clinical trials and naturalistic studies, aripiprazole once monthly (AOM) has been found to be effective and safe as acute and maintenance treatment options for schizophrenia. However, such clinical data have been presented in selected patient population (i.e., antipsychotic monotherapy, etc.), in particular, clinical information on switching to AOM from antipsychotic polypharmacy and/or other long acting injectable antipsychotics (LAIs) has been scarce till today.MethodsThe study period was from the first switching day to AOM up to 12 months in patients with antipsychotic polypharmacy (APpoly)/LAIs (baseline, month 3, month 6, and month 12). Available demographics and clinical information were retrieved from electronic medical records (EMRs). Available scores of Global Assessment of Functioning (GAF), Clinical Global Impression-Clinical Benefit (CGI-CB), CGI-severity, Visual Analog Scale on Satisfaction-Patient/Health Professional (VAS-P/HP), and the Positive and Negative Syndrome Scale-Insigh (PANSS-I) scores were also taken from EMR. Proportional change of functional impairment before and after AOM was also captured.ResultsData of 18 patients were available. Most commonly used combined APs before AOM were aripiprazole, blonanserin, quetiapine, and risperidone. At least 2 APs (n = 2.4) were combined before AOM. Scores of GAF (10.7% increase), CGI-CB (46.2% decrease), VAS-P (47.8% increase), VAS-HP (40.8% increase), and PANSS-I (27.9% increase) (all p = 0.001) were significantly improved from baseline to month 12, respectively. Approximately 59% of patients improved individual functioning with different level (i.e., employment, back to school, etc.) after AOM treatment at month 12.ConclusionThe present study have clearly shown the clinical benefit and utility of switching to AOM for treatment of patients with APpoly/LAIs in routine practice. Subsequent, adequately-powered, well-controlled clinical trials may be necessary to confirm our findings in near future.

Project description:Treatment with long-acting injectable (LAI) antipsychotic medication is an important element of relapse prevention in schizophrenia. Recently, the intramuscular once-monthly formulation of aripiprazole received marketing approval in Europe and the United States for schizophrenia.This study aimed to compare aripiprazole once-monthly with other LAI antipsychotics in terms of efficacy, tolerability, and safety.A systematic literature review was conducted to identify relevant double-blind randomized clinical trials of LAIs conducted in the maintenance treatment of schizophrenia. MEDLINE, MEDLINE In-Process, Embase, the Cochrane Library, PsycINFO, conference proceedings, clinical trial registries, and the reference lists of key review articles were searched. The literature search covered studies dating from January 2002 to May 2013.Studies were required to have ?24 weeks of follow-up. Patients had to be stable at randomization. Studies were not eligible for inclusion if efficacy of acute and maintenance phase treatment was not reported separately. Six trials were identified (0.5% of initially identified studies), allowing comparisons of aripiprazole once-monthly, risperidone LAI, paliperidone palmitate, olanzapine pamoate, haloperidol depot, and placebo.Data extracted included study details, study duration, the total number of patients in each treatment arm, efficacy, tolerability, and safety outcomes. The efficacy outcome contained the number of patients that experienced a relapse, tolerability outcomes included the number of patients that discontinued treatment due to treatment-related adverse events (AEs), and that discontinued treatment due to reasons other than AEs (e.g., loss to follow-up). Safety outcomes included the incidence of clinically relevant weight gain and extrapyramidal symptoms.Data were analyzed by applying a mixed treatment comparison competing risks model (efficacy) and using binary models (safety). There was no statistically significant difference between any study outcome, including the risk of relapse, the risk of discontinuations, and safety outcomes.Aripiprazole once-monthly is similarly efficacious to other LAIs with relatively low rates of discontinuation due to AEs and due to reasons other than AEs than other LAIs.

Project description:BackgroundA post hoc analysis from a multiphase trial with open-label transition and maintenance phases, a double-blind relapse prevention phase, and an optional open-label extension examined the long-term tolerability with continuous once-monthly injectable paliperidone palmitate 39, 78, 117, or 156 mg (25, 50, 75, or 100 mg equivalents [mg eq] of paliperidone) in subjects with recently diagnosed (≤5 years; n = 216) versus chronic illness (>5 years; n = 429) schizophrenia.MethodsAdverse events reported at a ≥2% margin between subgroups were identified. Relative risks (in the recently diagnosed compared with the chronically ill) and 95% confidence intervals (CI) were determined, and CI not including 1 were considered potentially significant.ResultsIn both subgroups, the mean monthly dose was 109 mg (69.9 mg eq). Continuous mean exposures were 333.9 ± 271.9 and 308.7 ± 278.3 days in the recently diagnosed and chronic illness subgroups, respectively. Using the criteria outlined in the methods, nasopharyngitis was a potentially significant event reported in more chronically ill than recently diagnosed subjects at months 6, 9, 12, and endpoint (7.2% versus 2.8%; relative risk 0.384; 95% CI 0.163-0.907). Influenza (2.8% versus 0.7%; relative risk 3.9; 95% CI 1.003-15.730) and amenorrhea (3.2% versus 0.9%; relative risk 3.476; 95% CI 1.029-11.744) at endpoint were potentially significant events in more recently diagnosed than chronically ill subjects. Mean weight changes, sedation/somnolence, any extrapyramidal symptom-related or glucose-related events were generally similar between the groups. The mean prolactin level increased in both sexes in both subgroups (changes from baseline of +41.8 ng/mL and +26.5 ng/mL in recently diagnosed and chronic illness females and +12.3 ng/mL and +15.1 ng/mL in recently diagnosed and chronic illness males, respectively), and were higher in females with recently diagnosed illness than in females who were chronically ill (P = 0.0002 at endpoint). Prolactin-related events were reported by 7.9% of recently diagnosed subjects with schizophrenia and 3.5% of those who were chronically ill.ConclusionThe long-term tolerability of paliperidone palmitate was generally similar in recently diagnosed schizophrenia subjects and those with more chronic illness, with the exception of some prolactin-related measures.

Project description:Objective: To evaluate the effect of aripiprazole once-monthly 400 mg (AOM 400; Abilify Maintena®) on symptom stability in acute treatment and maintenance therapy settings in patients with schizophrenia. Methods: Results were analyzed from two pivotal maintenance studies (Studies 246 and 247), a long-term (52 weeks), open-label extension of these studies (Study 248), an open-label, mirror-image study in patients switching from oral to long-acting injectable antipsychotic therapy (Study 283), and a study of AOM 400 in the acute setting (Study 291). Symptom stability was assessed using the Positive and Negative Syndrome Scale (PANSS) and the Clinical Global Impression (CGI) scale (CGI-Severity of Illness and CGI-Improvement). Results are reported for the total study population and in subgroups stratified by age. Results: In Study 246, AOM 400 resulted in significantly greater improvements from baseline vs placebo on all measures of symptom stability, with improvements maintained through 52 weeks. In Study 247, a non-inferiority study, AOM 400 resulted in improvements in PANSS and CGI scores comparable or significantly greater at all timepoints vs oral aripiprazole. In Study 248, AOM 400 resulted in the long-term stability of symptom improvements from the earlier studies. In Study 283, AOM 400 resulted in significant improvements from baseline in PANSS and CGI scores over 24 weeks. In Study 291, AOM 400 resulted in significantly greater improvements from baseline in PANSS and CGI scores vs placebo at all post-baseline timepoints. In post hoc analyses, AOM 400 showed similar efficacy in symptom improvement in adult patients aged ≤35 years and >35 years, with some evidence of a larger treatment effect on PANSS negative symptoms among younger patients in the acute treatment setting. Conclusion: In acute treatment and maintenance therapy settings, AOM 400 was effective in the rapid stabilization and long-term maintenance of symptoms in patients with schizophrenia.

Project description:To compare hospitalization rates in patients with schizophrenia treated prospectively with aripiprazole once-monthly 400 mg (AOM 400; an extended-release injectable suspension) vs the same patients' retrospective rates with their prior oral anti-psychotic therapy.Multi-center, open-label, mirror-image, naturalistic study in a community setting in North America. Patients who required a change in treatment and/or would benefit from long-acting injectable anti-psychotic therapy were treated prospectively for 6 months with AOM 400. Retrospective data on hospitalization rates were obtained.ClinicalTrials.gov: NCT01432444.The proportion of patients with ? 1 psychiatric inpatient hospitalization with oral anti-psychotic therapy examined retrospectively (months -4 to -1 before oral conversion) and after switching to AOM 400 (months 4-6 after initiating AOM 400).Psychiatric hospitalization rates were significantly lower when patients were treated with AOM 400 compared with oral anti-psychotic therapy both in the 3-month primary efficacy sample (2.7% [n = 9/336] vs 27.1% [n = 91/336], respectively; p < 0.0001) and in the total sample (6-month prospective rate: 8.8% [n = 38/433] vs 6-month retrospective rate: 38.1% [n = 165/433]; p < 0.0001). Discontinuations due to adverse events (AEs) during cross-titration were lower in patients cross-titrated on oral aripiprazole for >1 and <4 weeks (2.9% [n = 7/239]) compared with patients cross-titrated for ? 1 week (10.4% [n = 5/48]). The most common treatment-emergent AEs during the prospective treatment phase were insomnia (6.7% [n = 29/431]) and akathisia (6.5% [n = 28/431]). Patient-rated injection-site pain decreased from the first injection to the last visit.In a community setting, patients with schizophrenia demonstrated significantly lower psychiatric hospitalization rates after switching from their prior oral anti-psychotic therapy to AOM 400. Patients served as their own control, and thus an active control group was not included in this study. Confounding factors, such as insurance coverage and availability of hospital beds, were not examined here and deserve further consideration.

Project description:BACKGROUND:The long-acting injectable antipsychotic aripiprazole once-monthly 400 mg (AOM 400) was recently approved for maintenance treatment of bipolar I disorder (BP-I). The purpose of this study was to evaluate the safety, tolerability, and efficacy of AOM 400 as long-term maintenance treatment for BP-I. METHODS:This open-label multicenter study evaluated the effectiveness of AOM 400 as maintenance treatment for BP-I by assessing safety and tolerability (primary objective) and efficacy (secondary objective). The study enrolled AOM 400-naive ("de novo") patients as well as AOM 400-experienced ("rollover") patients with BP-I from a lead-in randomized, placebo-controlled clinical trial that demonstrated the efficacy of AOM 400 in the maintenance treatment of BP-I (Calabrese et al. in J Clin Psychiatry 78:324-331, 2017). Safety variables included frequency and severity of treatment-emergent adverse events (TEAEs) and TEAEs resulting in study discontinuation. Efficacy was assessed by the proportion of patients maintaining stability throughout the maintenance phase, as well as mean changes from baseline in Young Mania Rating Scale (YMRS), Montgomery-Asberg Depression Rating Scale, and Clinical Global Impressions for Bipolar Disorder-Severity of Illness Scale (CGI-BP-S) total scores. Patient acceptability and tolerability of treatment was assessed using the Patient Satisfaction with Medication Questionnaire-Modified. RESULTS:Of 464 patients entering the maintenance phase, 379 (82%) were de novo and 85 (18%) were rollover. TEAEs were more common in de novo than rollover patients. The overall discontinuation rate due to TEAEs was 10.3% (48/464). Improvements in YMRS and CGI-BP-S total scores were maintained during the study, and the vast majority of both de novo (87.0%) and rollover (97.6%) patients maintained stability through their last visit. Overall, the need for rescue medication during the maintenance phase was minimal (<?10% of patients). Patient satisfaction levels were high, with both de novo and rollover patients rating the side effect burden of AOM 400 as greatly improved relative to previous medications. CONCLUSION:AOM 400 was safe, effective, and well tolerated by both de novo and AOM 400-experienced patients with BP-I for long-term maintenance treatment.
