Abstract
Objective This study aims to compare the hospitalization rate in individuals with schizophrenia who started their treatment with aripiprazole once monthly (AOM400) or atypical oral antipsychotics (OA) in Spain. Methods This is an observational and retrospective study based on the electronic medical records from the BIG-PAC database. The study population consisted of individuals diagnosed with schizophrenia who initiated their treatment with AOM400 (AOM cohort) or atypical OA (OA cohort) from 01/01/2017 to 31/12/2019. A 1:1 propensity score matching (PSM) procedure was conducted to match individuals of both cohorts. The number and duration of hospitalizations, persistence to treatment, healthcare resources use, and costs were analyzed after 12 months. Results After the PSM, 1,017 individuals were included in each cohort [age: 41.4 years (SD: 10.6); males: 54.6%]. During the follow-up period, the AOM cohort had a 40% lower risk of hospitalization than the OA group [HR: 0.60 (95% confidence interval, CI: 0.49-0.74)]. The median time to the first hospitalization was longer in individuals with AOM400 compared to those with OA (197 days compared to 174 days; p < 0.004), whereas hospital admissions were shorter (AOM400: 6 compared to OA: 11 days; p < 0.001). After 12 months, individuals receiving AOM400 were more persistent than those with OA (64.9% compared to 53.7%; p < 0.001). The OA cohort required more healthcare resources, mainly visits to primary care physicians, specialists, and emergency rooms than those receiving AOM400 (p ≤ 0.005 in all comparisons). AOM400 reduced the costs of hospitalizations, and emergency room, specialist and primary care visits by 50.4, 36.7, 16.1, and 10.9%, respectively, in comparison to the treatment with atypical OA. AOM400 led to annual cost savings of €1,717.9 per individual, from the societal perspective. Conclusion Aripiprazole once monthly reduces the number and duration of hospitalizations, together with the treatment costs of schizophrenia, as it reduces the use of healthcare resources and productivity losses in these individuals.

Abstract
Objective In 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. Methods The 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. Results Data 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. Conclusion The 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.

Abstract
Introduction: In this review, the authors discuss the role of long-acting injectable antipsychotics (LAIs) for schizophrenia, focusing on the effectiveness and new perspectives introduced by such treatment strategy. Despite their promising pharmacokinetic features and their potential advantages in medication adherence, clinical outcomes, and medical costs, LAIs are not habitually presented as an option for patients, especially in the early phase of schizophrenia.Areas covered: This review explores the panorama of available LAIs for the treatment of schizophrenia, first-episode of psychosis, approved indications, medical costs, medication adherence, side effects, effectiveness and differences between first-generation (FGA)-LAIs and second-generation (SGA)-LAIs.Expert Opinion: LAIs differ in terms of specific indications, approved injection sites, needle size, injection volume, injection interval as well as potential drug-drug interactions, and commonly reported adverse reactions. The approved indications have expanded beyond schizophrenia to include bipolar and schizoaffective disorder. SGA-LAIs are often preferred to FGA-LAIs. FGA-LAIs although are less chosen in new patients due to the induction of cognitive and extrapyramidal side effects, even if, on the other hand, many SGA-LAIs are burden by hyperprolactinemia and weight gain. After a review of the available evidence, insight is provided into the potential and current therapeutic opportunities offered by LAI antipsychotic formulations.

Abstract
Abstract
Paranoid schizophrenia is a chronic, psychotic disorder which can be treated with long-acting injectable (LAI) antipsychotic drugs. There are risperidone (Risperdal Consta®), olanzapine (Zypadhera®), paliperidone (Xepilon®) and aripiprazole (Abilify Maintena®) currently available.
The aim of this study was to present a case history of the patient to whom monthly injections of aripiprazole effectively prevented both relapses of psychotic symptoms and hospitalizations.
Case report: A 55-year-old male patient with a 13-year history of paranoid schizophrenia has been effectively treated with aripiprazole (LAI) (400mg, every 4 weeks). During the last 8 years of treatment his mental state has been stabilized, without any acute psychotic symptoms and without any anxiety, or violent behaviours. Moreover, there have been no psychotic symptoms, or suicidal thoughts, or tendencies recordered. Therefore, no hospitalization has been required. However, despite the treatment, negative symptoms such as blunted affect, cognitive dysfunction and social withdrawal have been sustained.
Discussion: The available articles on aripiprazole (LAI) treatment indicate that it was effective in reducing the positive and negative symptoms of schizophrenia, as well as reducing the frequency and duration of hospitalization. However, the case report of a patient who has not had relapses of psychotic symptoms and suicidal thoughts and has not been hospitalized during 8 years of treatment with aripiprazole (LAI) has not yet been reported.
Conclusions: Regular, long-term injections of aripiprazole (LAI) are very effective at preventing positive symptoms of schizophrenia development and preventing both suicidal thoughts and hospitalizations. Therefore, treatment with this drug in everyday practice should be increased.

Abstract
This study, based on the 'Servizi Territoriali Associati per la Ricerca' (STAR) Network Depot Study nationwide baseline data, explored whether individual symptoms severity and clusters might influence the prescription of paliperidone palmitate 1-month (PP1M) vs. aripiprazole monohydrate. The Brief Psychiatric Rating Scale (BPRS) was used to assess psychopathology and relevant symptoms clusters. Drug Attitude Inventory, 10 items, was used to test attitude towards medications. Adherence to treatments was rated according to the Kemp seven-point scale. We assessed for eligibility 451 individuals and, among them, we included 195 subjects (n = 117 who started PPM1 and n = 78 aripiprazole monohydrate). Individuals were comparable in terms of age, gender, treatment years, recent hospitalizations, previous long-acting injectable antipsychotic treatments, additional oral treatments, attitude toward drugs, medication adherence, and alcohol/substance-related comorbidities. Subjects starting PP1M presented higher BPRS overall (P = 0.009), positive (P = 0.015), and negative (P = 0.010) symptom scores compared to subjects starting aripiprazole monohydrate. Results were confirmed by appropriate regression models and propensity score matching analysis. No differences were found comparing the other BPRS subscale scores: affect, resistance, and activation. Clinicians may be more prone to prescribe PPM1, rather than aripiprazole monohydrate, to subjects showing higher overall symptom severity, including positive and negative symptoms. No additional clinical factors influenced prescribing attitudes in our sample.

The use of long-acting Aripiprazole in a multi-center, prospective, uncontrolled, open-label, cohort study in Germany: a report on global assessment of functioning and the WHO wellbeing index. BMC Psychiatry 2020; 20:77. [PMID: 32087718 PMCID: PMC7035668 DOI: 10.1186/s12888-020-02488-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Accepted: 02/10/2020] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND In this non-interventional study, the functionality and well-being of patients with schizophrenia with aripiprazole once-monthly (AOM) was evaluated under real-life conditions in a naturalistic population. METHODS This non-interventional, prospective, multicenter 6-month study included 242 predominantly symptomatically stable patients (mean age 43.1 ± 15.1 years, 55% male) who switched their treatment to AOM after 9.7 (± 22.3) months of oral treatment. Outcome parameters included functionality (Global Assessment of Functioning, GAF), patient's wellbeing (WHO-5 Well-Being Index, WHO-5), and both patient's and clinician's assessment of efficacy and tolerability of AOM. Treatment emergent adverse events (TRAE) were also recorded. RESULTS At baseline, the mean GAF score was 47.0 (±13.9), indicating that patients experienced serious impairment in functioning. A continuous increase to 60.2 (±17.0) during treatment was found, with a robust and significant increase already after 4 weeks. At study start, patients reported diminished wellbeing, with a mean score of 10.6 (±5.6) on the WHO-5 scale. During treatment, patient wellbeing increased continuously with strong and significant improvements even after 4 weeks and an overall improvement of 4.8 (±6.9) over the course of 6 months with an endpoint of 15.4 (±5.5). Stratification of these results showed that more pronounced effects were achieved in younger patients ≤35 years (p<0.05 for GAF). The effectiveness and tolerability of AOM was rated good/very good by most patients (89.2 and 93.7%) and physicians (91.4 and 96.8%). Only few TRAEs occurred. CONCLUSIONS Our results show a significant positive effect after initiation of AOM treatment in predominantly stable patients with schizophrenia on their functioning and wellbeing, which was even more pronounced in patients aged ≤35 years, thereby supporting previous randomized controlled findings under routine conditions in clinical practice.

Abstract
BACKGROUND Aripiprazole lauroxil (AL) is a long-acting injectable antipsychotic approved for treatment of schizophrenia in adults. Approved AL doses and dosing regimens include 441 mg monthly, 662 mg monthly, and 882 mg monthly or every 6 weeks (q6wk), as well as the most recently approved dose, 1064 mg, administered every 2 months. OBJECTIVE Pharmacokinetics, safety, and tolerability of an AL regimen with a dose interval of every 2 months (1064 mg) were compared with two other regimens available as monthly and q6wk options. METHODS This study evaluated pharmacokinetics of AL given at a higher dosage strength (1064 mg) and at a longer dose interval (every 8 weeks [q8wk]) than previously studied. Patients with schizophrenia or schizoaffective disorder entering this 44-week, phase I, open-label, multicenter study had no recent exposure to aripiprazole and were maintained on other oral antipsychotics throughout the study. Patients were randomized to one of three AL dose regimens for 24 weeks (four 1064-mg injections [q8wk], five 882-mg injections [q6wk], or seven 441-mg injections [q4wk], with the last AL exposure at week 24). Oral aripiprazole was prohibited. Patients were followed for an additional 20 weeks to assess terminal aripiprazole plasma concentrations and ongoing safety. Plasma concentration samples were obtained at regular intervals to provide pharmacokinetic data for the duration of AL exposure and to measure persistence of plasma aripiprazole concentrations after AL discontinuation. RESULTS Eligible patients received AL 1064 mg q8wk (n = 35), 882 mg q6wk (n = 34), or 441 mg q4wk (n = 35). Overall, 103/104 (99.0%) patients were taking concomitant non-aripiprazole oral antipsychotic medications during the study. All three AL dose regimens provided continuous exposure to aripiprazole. Mean aripiprazole concentrations from the 1064-mg q8wk regimen were comparable to the 882-mg q6wk regimen and higher than the 441-mg q4wk regimen. Overall incidence by group of any adverse events (AEs) throughout the study was 68.6% (1064 mg q8wk), 50.0% (882 mg q6wk), and 65.7% (441 mg q4wk). The most common AE across regimens was injection-site pain (range 8.6%-11.4%). Serious AEs were reported by eight patients (all but one [increased psychosis in one patient, 441-mg q4wk group] considered unrelated to study drug). Discontinuations due to AEs were reported for 2.9%, 11.8%, and 5.7% of patients receiving the 8-, 6-, and 4-week regimens, respectively. AEs of akathisia, dyskinesia, and dystonia occurred in 2.9%, 8.6%, and 5.7% of patients in the 1064-mg q8wk group, 8.8%, 0%, and 2.9% in the 882-mg q6wk group, and 8.6%, 0%, and 0% in the 441-mg q4wk group, respectively. CONCLUSIONS AL 1064 mg q8wk provided continuous exposure to aripiprazole throughout the 8-week dosing interval and had a safety profile consistent with the 4- and 6-week regimens. These findings were used to support FDA approval of the 1064-mg dose administered every 2 months. REGISTRATION Clinicaltrials.gov: NCT02320032.

Abstract
OBJECTIVE Safety and tolerability of long-term treatment with the long-acting antipsychotic aripiprazole lauroxil (AL) were evaluated in patients with schizophrenia. METHODS This was an international, multicenter, phase 3, 52-week safety study of 2 fixed doses of AL (441 mg or 882 mg intramuscular every 4 weeks). Safety endpoints included adverse events (AEs) and extrapyramidal symptoms (EPS) including akathisia, injection-site reactions (ISRs), and clinically relevant changes in metabolic and endocrine values. RESULTS Of 478 patients entering this study, 236 (49%) continued from a previous 12-week, phase 3 efficacy study of AL, and 242 (51%) were newly enrolled. Overall, 77% and 23% of patients received AL 882 mg (N = 368) and 441 mg (N = 110), respectively. AEs occurred in 50.4% of patients; most were mild (28.7%) or moderate (18.2%). The most common AEs were insomnia (8.4%) and increased weight (5.0%). Akathisia was reported as an AE in 3.8% of the overall population, with higher rates in patients initiating AL on study entry than those continuing on AL. EPS-related AEs occurred in 9.4% of patients, and AEs related to metabolic parameters were reported in 4.6% of patients. Weight gain was minimal (0.8 kg), and no clinically relevant changes were observed for metabolic parameters. The overall incidence of ISRs was 3.8%; most were associated with the initial injections in patients receiving their first injection in this study. CONCLUSION Long-term treatment with AL is generally well tolerated, with a safety profile consistent with that of oral aripiprazole. It is a suitable option for patients with schizophrenia.

Abstract
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.

Abstract
OBJECTIVE To evaluate the effect of aripiprazole once-monthly 400 mg (AOM 400; Abilify Maintena®) on personal and social functioning in patients with schizophrenia in both the acute treatment and maintenance therapy settings. METHODS Post hoc analyses were conducted on data from Study 291 (NCT01663532), a 12-week, randomized, double-blind, placebo-controlled trial conducted in patients who were experiencing an acute psychotic episode, and Study 248 (NCT00731549), a 52-week open-label extension of two randomized, controlled trials of AOM 400 as maintenance therapy. Assessment of functioning was made using the Personal and Social Performance (PSP) scale. In Study 291, results were stratified by age (≤35 years or >35 years). RESULTS In Study 291, 340 patients were included in the analysis (n=168 randomized to AOM 400 [n=49 aged ≤35 years, n=119 aged >35 years]; n=172 randomized to placebo [n=54 aged ≤35 years, n=118 aged >35 years]). In Study 248, 1,081 patients entered the open-label maintenance phase and 858 completed the study. In Study 291, AOM 400, compared with placebo, resulted in a significant increase (improvement) in PSP scores based on LSM (SE) changes from baseline to Week 12 in patients aged ≤35 years (20.6 [1.9] for AOM 400 vs 9.5 [2.4] for placebo; P=0.001) and a numerically (but not significantly) larger increase in PSP scores in patients aged >35 years (16.1 [1.7] for AOM 400 vs 12.5 [1.9] for placebo; P=0.093). Improvements in both age groups met criteria for a minimally important clinical difference (7-10 points). In Study 248, AOM 400 resulted in either numerical improvements (increases) from baseline in PSP total score or maintenance of stable baseline values throughout the study. CONCLUSION AOM 400 was effective in improving personal and social functioning during acute treatment and maintaining function during long-term treatment.

Calabrese JR, Sanchez R, Jin N, Amatniek J, Cox K, Johnson B, Perry PP, Hertel P, Such P, McQuade RD, Nyilas M, Carson WH. The safety and tolerability of aripiprazole once-monthly as maintenance treatment for bipolar I disorder: A double-blind, placebo-controlled, randomized withdrawal study. J Affect Disord 2018; 241:425-432. [PMID: 30145513 DOI: 10.1016/j.jad.2018.06.043] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/21/2018] [Revised: 06/12/2018] [Accepted: 06/15/2018] [Indexed: 12/01/2022]
Abstract
BACKGROUND Aripiprazole once-monthly 400 mg (AOM 400), an atypical long-acting injectable antipsychotic, has demonstrated efficacy and safety in maintenance treatment of bipolar I disorder (BP-I). We further assess safety and tolerability and characterize adverse events (AEs) across the duration of aripiprazole exposure. METHODS Patients with BP-I were stabilized on oral aripiprazole (2-8 weeks), AOM 400 (12-28 weeks), followed by 1:1 randomization of patients meeting stability criteria to a 52-week, double-blind, placebo-controlled withdrawal phase. Treatment-emergent AEs (TEAEs) were collected across study phases. AEs were counted in a phase if they were drug-related and continued from the baseline of that phase. A separate analysis on new-onset akathisia was conducted. RESULTS Among TEAEs occurring in ≥10% of patients during all study phases were akathisia (23.3%) and weight increased (10.6%). Median time to akathisia onset was 20 days after starting oral aripiprazole; median duration was 29 days for the first occurrence; 21/168 patients (12.5%) reporting akathisia experienced >1 episode. Episodes of new-onset akathisia decreased over time, with few events reported in the randomized phase. Weight gain was minimal with oral aripiprazole, generally starting within 3 months after the first AOM 400 injection, and appearing to plateau at 36 weeks. The mean weight gain within any study phase was ≤1.0 kg. Potentially clinically significant changes in metabolic parameters were uncommon. LIMITATIONS Patients on placebo had AOM 400 exposure before randomization. CONCLUSION These findings suggest that AEs with AOM 400 treatment were time-limited and support AOM 400 as a well-tolerated maintenance treatment of BP-I.

Naber D, Baker RA, Eramo A, Forray C, Hansen K, Sapin C, Peters-Strickland T, Nylander AG, Hertel P, Nitschky Schmidt S, Loze JY, Potkin SG. Long-term effectiveness of aripiprazole once-monthly for schizophrenia is maintained in the QUALIFY extension study. Schizophr Res 2018; 192:205-210. [PMID: 28433498 DOI: 10.1016/j.schres.2017.04.013] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2016] [Revised: 04/03/2017] [Accepted: 04/04/2017] [Indexed: 11/30/2022]
Abstract
OBJECTIVE To evaluate long-term safety and effectiveness of continued treatment with aripiprazole once-monthly 400mg (AOM 400) in patients with schizophrenia. METHODS Patients who completed the QUALIFY study (NCT01795547) in the AOM 400 arm were eligible for 6 additional once-monthly injections of AOM 400 during an open-label, 24-week extension (NCT01959035). Safety data were collected at each visit. Effectiveness measures included change from baseline in health-related qualify of life and functioning on the Heinrichs-Carpenter Quality of Life scale (QLS) and Clinical Global Impression - Severity (CGI-S) scale. RESULTS Of the 88 patients enrolled, 77 (88%) completed the extension study. Most common treatment-emergent adverse events (incidence ≥2%) were weight increased (6/88, 7%), toothache (3/88, 3%) and headache (3/88, 3%). Effectiveness was maintained during the extension study, with small but continued improvements from baseline: the least squares mean (LSM) change (95% CI) from baseline to week 24 was 2.32 (-1.21 to 5.85) for the QLS total score and -0.10 (-0.26 to 0.06) for the CGI-S score. The aggregated LSM change (95% CI) from baseline of the lead-in study to week 24 of the extension study was 11.54 (7.45 to 15.64) for the QLS total score and -0.98 (-1.18 to -0.79) for the CGI-S score. CONCLUSIONS AOM 400 was well tolerated in patients continuing AOM treatment during the extension phase of the QUALIFY study. Robust and clinically meaningful improvements in health-related quality of life and functioning were maintained, further supporting the long-term clinical benefits of AOM 400 for the treatment of patients with schizophrenia.
