RESUMO

Background: Two open-label, randomized, parallel-arm studies compared pharmacokinetics, safety, and tolerability of aripiprazole once-monthly 400 mg following deltoid vs gluteal injection in patients with schizophrenia. Methods: In the single-dose study, 1 injection of aripiprazole once-monthly 400 mg in the deltoid (n=17) or gluteal (n=18) muscle (NCT01646827) was administered. In the multiple-dose study, the first aripiprazole once-monthly 400 mg injection was administered in either the deltoid (n=71) or gluteal (n=67) muscle followed by 4 once-monthly deltoid injections (NCT01909466). Results: After single-dose administration, aripiprazole exposure (area under the concentration-time curve) was similar between deltoid and gluteal administrations, whereas median time to maximum plasma concentration was shorter (7.1 [deltoid] vs 24.1 days [gluteal]) and maximum concentration was 31% higher after deltoid administration. In the multiple-dose study, median time to maximum plasma concentration for deltoid administration was shorter (3.95 vs 7.1 days), whereas aripiprazole mean trough concentrations, maximum concentration, and area under the concentration-time curve were comparable between deltoid and gluteal muscles (historical data comparison). Multiple-dose pharmacokinetic results for the major metabolite, dehydro-aripiprazole, followed a similar pattern to that of the parent drug for both deltoid and gluteal injection sites. Safety and tolerability profiles were similar after gluteal or deltoid injections. Based on observed data, minimum aripiprazole concentrations achieved by aripiprazole once-monthly 400 mg are comparable with those of oral aripiprazole 15 to 20 mg/d. Conclusions: The deltoid muscle is a safe alternative injection site for aripiprazole once-monthly 400 mg in patients with schizophrenia.

RESUMO

Background: QUALIFY was a 28-week, randomized, open-label, head-to-head trial that assessed improvements across multiple measures in stable patients with schizophrenia with aripiprazole once-monthly 400 mg vs paliperidone palmitate. Methods: Secondary effectiveness assessments included physician-rated readiness for work using the Work Readiness Questionnaire, the Clinical Global Impression-Severity and Clinical Global Impression-Improvement scales, and quality of life with the rater-blinded Heinrichs-Carpenter Quality of Life Scale. Patients assessed their treatment satisfaction and quality of life with Subjective Well-Being under Neuroleptic Treatment-short version and Tolerability and Quality of Life questionnaires. Results: Odds of being ready for work at week 28 were significantly higher with aripiprazole once-monthly 400 mg vs paliperidone palmitate (adjusted odds ratio, 2.67; 95% CI, 1.39-5.14; P=.003). Aripiprazole once-monthly 400 mg produced numerically or significantly greater improvements from baseline vs paliperidone palmitate in all Quality of Life Scale items. With aripiprazole once-monthly 400 mg vs paliperidone palmitate at week 28, there were significantly more Clinical Global Impression-Severity and Clinical Global Impression-Improvement responders (adjusted odds ratio, 2.26; P=.010, and 2.51; P=.0032) and significantly better Clinical Global Impression-Improvement scores (least squares mean treatment difference, -0.326; 95% CI, -0.60 to -0.05; P=.020). Numerically larger improvements with aripiprazole once-monthly 400 mg vs paliperidone palmitate were observed for patient-rated scales Subjective Well-Being under Neuroleptic Treatment-short version and Tolerability and Quality of Life. Partial correlations were strongest among clinician-rated and among patient-rated scales but poorest between clinician and patient-rated scales. Conclusions: Consistently greater improvements were observed with aripiprazole once-monthly 400 mg vs paliperidone palmitate across all measures. Partial correlations between scales demonstrate the multidimensionality of various measures of improvement. More patients on aripiprazole once-monthly 400 mg were deemed ready to work by the study end.

RESUMO

BACKGROUND: Long-acting injectable antipsychotics are treatment options for acute and long-term treatment of patients with schizophrenia. In a previously published 12-week randomized, double-blind, placebo-controlled clinical trial of patients with schizophrenia experiencing an acute psychotic episode, aripiprazole once-monthly 400 mg (AOM 400) produced significantly greater improvement than placebo on the primary endpoint, Positive and Negative Syndrome Scale (PANSS) total score at week 10. METHODS: To examine the efficacy of AOM 400 across a broader representation of schizophrenia symptoms, including agitation, a post hoc analysis of this trial was carried out to assess the change in PANSS Marder factor domains (positive symptoms, negative symptoms, disorganized thought, uncontrolled hostility/excitement, and anxiety/depression) and the PANSS excited component (equivalent to Marder factor domain uncontrolled hostility/excitement plus the tension item) by comparing differences in change from baseline between AOM 400 and placebo using a mixed model for repeated measures. RESULTS: The differences between treatment and placebo for all factors were statistically significant, with improvements seen as early as week 1 or 2, and maintained through week 12. Thus, AOM 400, supplemented with oral aripiprazole in the first 2 weeks, showed significantly greater efficacy versus placebo in acutely ill patients with schizophrenia in all 5 Marder illness domains, as well as in agitation as conceptualized by the PANSS excited component score. CONCLUSIONS: These findings indicate that AOM 400 is efficacious across the spectrum of schizophrenia symptoms in acutely ill patients, with implications for both short-term and, by extension, long-term patient outcomes.

RESUMO

OBJECTIVE: To assess the effects of aripiprazole once-monthly 400 mg (AOM 400) on clinical symptoms and global improvement in schizophrenia after switching from an oral antipsychotic. METHODS: In a multicenter, open-label, mirror-image, naturalistic study in patients with schizophrenia (>1 year, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision [DSM-IV-TR] criteria), changes in efficacy measures were assessed during prospective treatment (6 months) with AOM 400 after switching from standard-of-care oral antipsychotics. During prospective treatment, patients were cross-titrated to oral aripiprazole monotherapy (1-4) weeks followed by open-label AOM 400 (24 weeks). Mean change from baseline of the open-label AOM 400 phase in Positive and Negative Syndrome Scale (PANSS) scores (total, positive and negative subscales) and Clinical Global Impression-Severity (CGI-S) scores; mean CGI-Improvement (CGI-I) score; and proportion of responders (≥30% decrease from baseline in PANSS total score or CGI-I score of 1 [very much improved] or 2 [much improved]) were assessed. RESULTS: PANSS and CGI-S scores improved from baseline (P<0.0001) and CGI-I demonstrated improvement at all time points. By the end of the study, 49.0% of patients were PANSS or CGI-I responders. CONCLUSIONS: In a community setting, patients with schizophrenia who were stabilized at baseline and switched to AOM 400 from oral antipsychotics showed clear improvements in clinical symptoms.

RESUMO

BACKGROUND: Long-acting injectable formulations of antipsychotics are treatment alternatives to oral agents. AIMS: To assess the efficacy of aripiprazole once-monthly compared with oral aripiprazole for maintenance treatment of schizophrenia. METHOD: A 38-week, double-blind, active-controlled, non-inferiority study; randomisation (2:2:1) to aripiprazole once-monthly 400 mg, oral aripiprazole (10-30 mg/day) or aripiprazole once-monthly 50 mg (a dose below the therapeutic threshold for assay sensitivity). ( TRIAL REGISTRATION: clinicaltrials.gov, NCT00706654.) RESULTS: A total of 1118 patients were screened, and 662 responders to oral aripiprazole were randomised. Kaplan-Meier estimated impending relapse rates at week 26 were 7.12% for aripiprazole once-monthly 400 mg and 7.76% for oral aripiprazole. This difference (-0.64%, 95% CI -5.26 to 3.99) excluded the predefined non-inferiority margin of 11.5%. Treatments were superior to aripiprazole once-monthly 50 mg (21.80%, P < or = 0.001). CONCLUSIONS: Aripiprazole once-monthly 400 mg was non-inferior to oral aripiprazole, and the reduction in Kaplan-Meier estimated impending relapse rate at week 26 was statistically significant v. aripiprazole once-monthly 50 mg.

RESUMO

Purpose: A recent, phase 3b, mirror-image clinical trial of outpatients with schizophrenia found that use of aripiprazole tablets with sensor (AS; Abilify MyCite®, comprising an ingestible event-marker sensor embedded in aripiprazole tablets, wearable sensor patches, and a smartphone application) reduced the incidence of psychiatric hospitalizations relative to oral standard-of-care antipsychotics. This analysis explored the relationship between AS engagement by participants and changes in participant performance and symptom-severity measures assessed by clinical raters. Participants and Methods: This post hoc analysis used prospectively collected clinical data from a phase 3b clinical trial (NCT03892889). Outpatients had schizophrenia, were aged 18-65 years, and had ≥ 1 psychiatric hospitalization in the previous 48 months. Participants were grouped by study completion status and a k-means clustering algorithm based on AS utilization, resulting in 3 groups: discontinued (discontinued AS before month 3 of the study); moderate engagement (completed 3 months, used AS intermittently); and high engagement (completed 3 months, used AS regularly). Baseline to end-of-study differences for the Clinical Global Impression Scale (Severity of Illness and Improvement of Illness scales), Personal and Social Performance Scale, and Positive and Negative Syndrome Scale were calculated. Results: A total of 277 outpatients were enrolled (discontinued, n = 164; moderate engagement, n = 63; high engagement, n = 50). All groups experienced symptom improvement from baseline to end-of-study, with significant changes in the more-engaged groups. Highly engaged participants showed significant improvement for all clinical scores and subscores (all P < 0.05) and demonstrated significantly more improvement in symptoms than participants with less engagement. Conclusion: Participants who completed 3 months of the study and had higher AS engagement experienced significantly greater improvement in their end-of-study clinical assessments versus participants who did not complete 3 months. Improvement may be related to more-consistent medication intake and better engagement with a digital health system.

RESUMO

Objective: Inpatient psychiatric admissions drive the financial burden of schizophrenia, and medication adherence remains challenging. We assessed whether aripiprazole tablets with sensor (AS; system includes ingestible event-marker sensor, wearable sensor patches, and smartphone application) could reduce psychiatric hospitalizations compared with oral standard-of-care (SOC) antipsychotics.Methods: This phase 3b, mirror-image clinical trial was conducted from April 29, 2019-August 11, 2020, in adults with schizophrenia with ≥ 1 hospitalization in the previous 48 months who had been prescribed oral SOC for the preceding 6 months (retrospective phase). All participants used AS for at least 3 months and up to 6 months. Primary endpoint was the inpatient psychiatric hospitalization rate in the modified intent-to-treat (mITT; n = 113) population during prospective months 1-3 versus retrospective phase. Proportion of days covered by medication was the secondary endpoint. Safety endpoints included adverse events related to the medication or patch and suicidality.Results: AS significantly reduced hospitalizations during prospective months 1-3 (-9.7%) and months 1-6 (-21.3% [P ≤ .001 for all comparisons]) in the mITT population versus the corresponding retrospective phase. AS use improved confirmed medication ingestion by 26.5 percentage points in prospective months 1-3 (P ≤ .001) and reduced PANSS scores. Patches were well-tolerated, and no participant reported changes in suicide risk.Conclusions: Compared with oral SOC, AS reduced inpatient psychiatric hospitalization rates for adults with mild-to-moderate schizophrenia. The AS system may aid medication ingestion and is associated with improvements in symptoms, potentially reducing acute-care needs among patients with schizophrenia.Trial Registration: ClinicalTrials.gov identifier: NCT03892889.

RESUMO

BACKGROUND: Adherence to medication regimens and patient rest are two important factors in the well-being of patients with serious mental illness. Both of these behaviors are traditionally difficult to record objectively in unsupervised populations. OBJECTIVE: A digital medicine system that provides objective time-stamped medication ingestion records was used by patients with serious mental illness. Accelerometer data from the digital medicine system was used to assess rest quality and thus allow for investigation into correlations between rest and medication ingestion. METHODS: Longest daily rest periods were identified and then evaluated using a k-means clustering algorithm and distance metric to quantify the relative quality of patient rest during these periods. This accelerometer-derived quality-of-rest metric, along with other accepted metrics of rest quality, such as duration and start time of the longest rest periods, was compared to the objective medication ingestion records. Overall medication adherence classification based on rest features was not performed due to a lack of patients with poor adherence in the sample population. RESULTS: Explorations of the relationship between these rest metrics and ingestion did seem to indicate that patients with poor adherence experienced relatively low quality of rest; however, patients with better adherence did not necessarily exhibit consistent rest quality. This sample did not contain sufficient patients with poor adherence to draw more robust correlations between rest quality and ingestion behavior. The correlation of temporal outliers in these rest metrics with daily outliers in ingestion time was also explored. CONCLUSIONS: This result demonstrates the ability of digital medicine systems to quantify patient rest quality, providing a framework for further work to expand the participant population, compare these rest metrics to gold-standard sleep measurements, and correlate these digital medicine biomarkers with objective medication ingestion data.

RESUMO

BACKGROUND: Brexpiprazole is a dopamine/serotonin receptor partial agonist (D2, 5-HT1A) and antagonist (5-HT2A) approved for treatment of schizophrenia and major depressive disorder (adjunct to antidepressants). AIMS: This study aimed to investigate brexpiprazole as monotherapy in acute mania (bipolar I disorder) in two short-term (ST) studies (study 080 and study 081) and one open-label (OL) extension (study 083). METHODS: ST studies were three-week randomized, double-blind, flexible dose (2-4 mg/day), placebo-controlled studies. The primary endpoint was mean change in Young Mania Rating Scale (YMRS) total score from baseline to day 21. The OL study was a 26-week flexible dose (2-4 mg/day) study for patients completing the ST studies. RESULTS: A total of 164 and 158 (study 080) and 170 and 162 (study 081) inpatients with DSM-5 mania with/without mixed features were randomized to placebo or brexpiprazole, respectively. The primary analyses did not show a statistically significant difference between brexpiprazole and placebo: study 080: least squares mean difference (95% confidence limits): 0.14 (-1.74, 2.03), p = 0.8797; study 081: -1.62 (-3.56, 0.32), p = 0.1011. OL study patients (n = 381) demonstrated a gradual improvement in YMRS total score. Akathisia was the only adverse event, with an incidence of ⩾5% with brexpiprazole and more than placebo in the ST studies, or ⩾5% in the OL study. Brexpiprazole was more efficacious in patients with impaired or no insight (predominantly EU patients) than in patients with excellent insight (predominantly US patients). CONCLUSIONS: Further studies are necessary to address the potential efficacy of brexpiprazole in acute mania, which should ensure that the study sample is severe enough (especially with regard to insight), and that the dose/titration schedule is not too modest.

RESUMO

PURPOSE: Symptoms of psychotic disorders can complicate efforts to accurately evaluate patients' medication ingestion. The digital medicine system (DMS), composed of antipsychotic medication co-encapsulated with an ingestible sensor, wearable sensor patches, and a smartphone application, was developed to objectively measure medication ingestion. We assessed performance and acceptance of the DMS in subjects with psychotic disorders. METHODS: This was an 8-week open-label, single-arm, multicenter, Phase 4 pragmatic study (NCT03568500; EudraCT #2017-004602-17). Eligible adults were diagnosed with schizophrenia, schizoaffective disorder, or first-episode psychosis; were receiving aripiprazole, quetiapine, olanzapine, or risperidone; and could use the DMS with the application downloaded on a personal smartphone. The primary endpoint was good patch coverage, defined as the proportion of days over the assessment period where ≥80.0% of patch data was available, or an ingestion was detected. Exploratory endpoints included a survey on user satisfaction, used to assess acceptance of the DMS. Safety analyses included the incidence of treatment-emergent adverse events (TEAEs). RESULTS: From May 25, 2018 to March 22, 2019, 55 subjects were screened and 44 were enrolled. Good patch coverage was achieved on 63.4% of days assessed and the DMS generated an adherence metric of ≥80.0%, reflecting the percentage of ingestion events expected when good patch coverage was reported. Most subjects (53.5%) were satisfied with the DMS. Medical device skin irritations were the only TEAEs reported. CONCLUSION: The DMS had sufficient performance in, and acceptance from, subjects with psychotic disorders and was generally well tolerated.

RESUMO

The objective of this work was to adapt and evaluate the performance of a Bayesian hybrid model to characterize objective temporal medication ingestion parameters from two clinical studies in patients with serious mental illness (SMI) receiving treatment with a digital medicine system. This system provides a signal from an ingested sensor contained in the dosage form to a patient-worn patch and transmits this signal via the patient's mobile device. A previously developed hybrid Markov-von Mises model was used to obtain maximum-likelihood estimates for medication ingestion behavior parameters for individual patients. The individual parameter estimates were modeled to obtain distribution parameters of priors implemented in a Markov chain-Monte Carlo framework. Clinical and demographic covariates associated with model ingestion parameters were also assessed. We obtained individual estimates of overall observed ingestion percent (median:75.9%, range:18.2-98.3%, IQR:32.9%), rate of excess dosing events (median:0%, range:0-14.3%, IQR:3.0%) and observed ingestion duration. The modeling also provided estimates of the Markov-dependence probabilities of dosing success following a dosing success or failure. The ingestion-timing deviations were modeled with the von Mises distribution. A subset of 17 patients (22.1%) were identified as prompt correctors based on Markov-dependence probability of a dosing failure followed by a dosing success of unity. The prompt corrector sub-group had a better overall digital medicine ingestion parameter profile compared to those who were not prompt correctors. Our results demonstrate the potential utility of a Bayesian Hybrid Markov-von Mises model for characterizing digital medicine ingestion patterns in patients with SMI.

RESUMO

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.

RESUMO

BACKGROUND: The digital medicine system (DMS), a drug-device combination developed for patients with serious mental illness, integrates adherence measurement with pharmacologic treatment by embedding an ingestible sensor in a pill, allowing for information sharing among patients, health care providers (HCPs), and caregivers via a mobile interface. Studies conducted during the DMS development process aimed to minimize cognitive burden and use-related risks and demonstrated effective use of the technology. METHODS: Human factors (HF) studies assessed the system's safe and effective use by the intended users for the intended uses. The patient interface was tested in six formative HF studies followed by a validation study. The HCP/caregiver interface was tested in one study before validation. All tasks critical to safety or necessary for effective use were included. Formative studies identified use-related risks and the causes of use problems to guide design modification. Validation of the patient and HCP/caregiver interfaces assessed risks of the final product. RESULTS: During the patient formative studies, design improvements were made to address problems and mitigate risks thought to be associated with a suboptimal system design or patient understanding of the system. In the validation study of the patient interface, 35 patients attempted 23 performance tasks, for a total of 805 attempts; 783/805 attempts were completed with success. One close call, 15 failures, and 6 difficulties occurred on these user tasks; only 3 of these were on a critical task. Residual risks resistant to mitigation were found to be of low severity based on the US Food and Drug Administration 2016 guidance. CONCLUSION: The final design of the DMS reflects input by the intended user populations through a comprehensive development methodology. In alignment with the US Food and Drug Administration goals for HF studies, the system was found to be safe and effective for the intended users, uses, and use environments.

RESUMO

INTRODUCTION: Two risk minimization (RM) tools-a healthcare professional frequently asked questions (HCP-FAQs) brochure and a patient/caregiver information brochure (PCIB)-were developed for HCPs and for adolescents (aged ≥ 13 years) receiving aripiprazole for bipolar I mania and their caregivers. OBJECTIVES: This study evaluated the effectiveness of these RM tools in improving the awareness and education of HCPs and patients/caregivers. METHOD: The RM tools were distributed to HCPs (identified in agreement with the marketing authorization holder [MAH] and local regulatory authorities), who in turn distributed the PCIBs to patients/caregivers. A web-based survey was then conducted targeting HCPs and patients/caregivers. RESULTS: The response rate was low: 118 of 23,282 invited HCPs and 16 patients/caregivers completed the survey. Overall, 42% (49/118) of HCP respondents were aware of aripiprazole RM tools; of these, 59% (29/49) of HCPs read them at least once and 66% (19/29) of these used the RM tools while discussing the benefit-risk profile of aripiprazole with patients/caregivers. In total, 30 of the 118 HCPs (25%) were aware of the PCIB, and 26 distributed it to their patients/caregivers, whereas seven HCPs advised them to read the brochure. Overall, 15 of the 16 patients/caregivers were aware of the PCIB, and 13 read/referred to it. Of these, 12 found the PCIB useful, and five monitored their weight while receiving aripiprazole and reported potential risks immediately to their HCP. CONCLUSION: The response rate to the survey was low, and the tools displayed limited utility and effectiveness in improving awareness and education in a small number of responders. Therefore, the aripiprazole risk management plan was amended, and the tools were discontinued.

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.

RESUMO

BACKGROUND: Medication nonadherence is common in the treatment of serious mental illness (SMI) and leads to poor outcomes. The digital medicine system (DMS) objectively measures adherence with oral aripiprazole in near-real time, allowing recognition of adherence issues. This pilot study evaluated the functionality of an integrated call center in optimizing the use of the DMS. MATERIALS AND METHODS: An 8-week, open-label, single-arm trial at four US sites enrolled adults with bipolar I disorder, major depressive disorder, and schizophrenia on stable oral aripiprazole doses and willing to use the DMS (oral aripiprazole + ingestible event marker [IEM], IEM-detecting skin patch, and software application). Integrated call-center functionality was assessed based on numbers and types of calls. Ingestion adherence with prescribed treatment (aripiprazole + IEM) during good patch wear and proportion of time with good patch wear (days with ≥80% patch data or detected IEM) were also assessed. RESULTS: All enrolled patients (n=49) used the DMS and were included in analyses; disease duration overall approached 10 years. For a duration of 8 weeks, 136 calls were made by patients, and a comparable 160 calls were made to patients, demonstrating interactive communication. The mean (SD) number of calls made by patients was 2.8 (3.5). Approximately half of the inbound calls made by patients occurred during the first 2 weeks and were software application- or patch-related. Mean ingestion adherence was 88.6%, and corresponding good patch wear occurred on 80.1% of study days. CONCLUSION: In this pilot study, the integrated call center facilitated DMS implementation in patients with SMI on stable doses of oral aripiprazole. In clinical practice, the call center and the DMS will facilitate objective measurement of adherence and potentially improve rates of adherence in patients with SMI.

RESUMO

BACKGROUND: As the capabilities and reach of technology have expanded, there is an accompanying proliferation of digital technologies developed for use in the care of patients with mental illness. The objective of this review was to systematically search published literature to identify currently available health technologies and their intended uses for patients with serious mental illness. MATERIALS AND METHODS: The Medline, Embase, and BIOSIS Previews electronic databases were searched to identify peer-reviewed English language articles that reported the use of digital, mobile, and other advanced technology in patients with schizophrenia/schizoaffective disorder, bipolar disorder, and major depressive disorder. Eligible studies were systematically reviewed based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS: Eighteen studies that met the inclusion criteria were identified. Digital health technologies (DHTs) assessed in the selected studies included mobile applications (apps), digital medicine, digital personal health records, and an electronic pill container. Smartphone apps accounted for the largest share of DHTs. The intended uses of DHTs could be broadly classified as monitoring to gain a better understanding of illness, clinical assessment, and intervention. Overall, studies indicated high usability/feasibility and efficacy/effectiveness, with several reporting validity against established clinical scales. Users were generally engaged with the DHT, and mobile assessments were deemed helpful in monitoring disease symptoms. CONCLUSION: Rapidly proliferating digital technologies seem to be feasible for short-term use in patients with serious mental illness; nevertheless, long-term effectiveness data from naturalistic studies will help demonstrate their usefulness and facilitate their adoption and integration into the mental health-care system.

RESUMO

Schizophrenia is a chronic disease with negative impact on patients' employment status and quality of life. This post-hoc analysis uses data from the QUALIFY study to elucidate the relationship between work readiness and health-related quality of life and functioning. QUALIFY was a 28-week, randomized study (NCT01795547) comparing the treatment effectiveness of aripiprazole once-monthly 400 mg and paliperidone palmitate once-monthly using the Heinrichs-Carpenter Quality-of-Life Scale as the primary endpoint. Also, patients' capacity to work and work readiness (Yes/No) was assessed with the Work Readiness Questionnaire. We categorized patients, irrespective of treatment, by work readiness at baseline and week 28: No to Yes (n = 41), Yes to Yes (n = 49), or No at week 28 (n = 118). Quality-of-Life Scale total, domains, and item scores were assessed with a mixed model of repeated measures. Patients who shifted from No to Yes in work readiness showed robust improvements on Quality-of-Life Scale total scores, significantly greater than patients not ready to work at week 28 (least squares mean difference: 11.6±2.6, p<0.0001). Scores on Quality-of-Life Scale instrumental role domain and items therein-occupational role, work functioning, work levels, work satisfaction-significantly improved in patients shifting from No to Yes in work readiness (vs patients No at Week 28). Quality-of-Life Scale total scores also significantly predicted work readiness at week 28. Overall, these results highlight a strong association between improvements in health-related quality of life and work readiness, and suggest that increasing patients' capacity to work is an achievable and meaningful goal in the treatment of impaired functioning in schizophrenia.

RESUMO

Sexual dysfunction, a common side effect of antipsychotic medications, may be partly caused by dopamine antagonism and elevation of prolactin. In QUALIFY, a randomized study, aripiprazole once-monthly 400 mg (AOM 400), a dopamine D2 receptor partial agonist, showed noninferiority and subsequent superiority versus paliperidone palmitate (PP), a dopamine D2 receptor antagonist, on the Heinrichs-Carpenter Quality-of-Life Scale (QLS) in patients with schizophrenia aged 18-60 years. Sexual dysfunction (Arizona Sexual Experience Scale) and serum prolactin levels were also assessed. Odds for sexual dysfunction were lower with AOM 400 versus PP [week 28 adjusted odds ratio (95% confidence interval), 0.29 (0.14-0.61); P=0.0012] in men [0.33 (0.13-0.86); P=0.023], women [0.14 (0.03-0.62); P=0.0099], and patients aged 18-35 years [0.04 (<0.01-0.34); P=0.003]. Among patients shifting from sexual dysfunction at baseline to none at week 28, there was a trend toward greater improvement in the QLS total score. The mean (SD) prolactin concentrations decreased with AOM 400 [-150.6 (274.4) mIU/l] and increased with PP [464.7 (867.5) mIU/l] in both men and women. Six PP-treated patients experienced prolactin-related adverse events. In addition to greater improvement on QLS, patients had a lower risk for sexual dysfunction and prolactin elevation with AOM 400 versus PP in QUALIFY.

RESUMO

BACKGROUND: A digital medicine system (DMS) has been developed to measure and report adherence to an atypical antipsychotic, aripiprazole, in psychiatric patients. The DMS consists of 3 components: ingestible sensor embedded in a medication tablet, wearable sensor, and secure mobile and cloud-based applications. An umbrella study protocol was designed to rapidly assess the technical performance and safety of the DMS in multiple substudies to guide the technology development. METHODS: Two sequential substudies enrolled 30 and 29 healthy volunteers between March-April 2014 and February-March 2015, respectively, to assess detection accuracy of the ingestible sensor by the DMS and the latency period between ingestion and detection of the ingestion by the wearable sensor or the cloud-based server. RESULTS: The first substudy identified areas for improvement using early versions of the wearable sensor and the mobile application. The second substudy tested updated versions of the components and showed an overall ingestion detection rate of 96.6%. Mean latency times for the signal transmission were 1.1-1.3 minutes (from ingestion to the wearable sensor detection) and 6.2-10.3 minutes (from the wearable sensor detection to the server detection). Half of transmissions were completed in < 2 minutes, and ~90% of ingestions were registered by the smartphone within 30 minutes of ingestion. No serious adverse events, discontinuations, or clinically significant laboratory/vital signs findings were reported. CONCLUSIONS: The DMS implementing modified versions of the smartphone application and the wearable sensor has the technical capability to detect and report tablet ingestion with high accuracy and acceptable latency time. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02091882.
