Effects on health-related quality of life in patients treated with lurasidone for bipolar depression: results from two placebo controlled bipolar depression trials.

ABSTRACT: Depressive symptoms associated with bipolar disorder negatively impact health-related quality of life (HRQoL). The efficacy of lurasidone in reducing depressive symptoms has been previously demonstrated. The objective of this study was to examine the direct and indirect effect (mediated through improvement in depression symptoms) of lurasidone in improving patient HRQoL.A secondary analysis of data was conducted of two 6-week, double-blind, placebo-controlled trials assessing the effect of lurasidone (lurasidone monotherapy [20-60 mg/day or 80-120 mg/day]; lurasidone adjunctive to lithium or valproate [20-120 mg/day]) in patients with bipolar depression. Patient HRQoL was measured using the Quality of Life Enjoyment and Satisfaction Questionnaire Short Form (Q-LES-Q SF). Depression symptoms were measured using the Montgomery-Asberg Depression Rating Scale (MADRS). Analysis of covariance (ANCOVA) was used to estimate the effect of lurasidone on improvement in the Q-LES-Q SF percentage maximum score from baseline to 6 weeks. Path analysis was used to evaluate the total effect (?1), as well as the indirect (?2*?3) and direct (?4) effect of lurasidone on Q-LES-Q SF change through improvements in MADRS.A total of 340 and 485 patients from the monotherapy and adjunctive therapy, respectively, were included in the analysis. At 6-weeks, ANCOVA analyses demonstrated that lurasidone provided significant improvement in adjusted mean Q-LES-Q SF scores in comparison to placebo for monotherapy (22.9 and 22.7 vs. 15.2, both p?

Project description:BackgroundBipolar depression is characterized by depressive symptoms and impairment in many areas of functioning, including work, family, and social life. The objective of this study was to assess the independent, direct effect of lurasidone treatment on functioning improvement, and examine the indirect effect of lurasidone treatment on functioning improvement, mediated through improvements in depression symptoms.MethodsData from a 6-week placebo-controlled trial assessing the effect of lurasidone monotherapy versus placebo in patients with bipolar depression was used. Patient functioning was measured using the Sheehan disability scale (SDS). Descriptive statistics were used to assess the effect of lurasidone on improvement on the SDS total and domain scores (work/school, social, and family life), as well as number of days lost and unproductive due to symptoms. Path analyses evaluated the total effect (β1), as well as the indirect effect (β2×β3) and direct effect (β4) of lurasidone treatment on SDS total score change, using standardized beta path coefficients and baseline scores as covariates. The direct effect of treatment on SDS total score change and indirect effects accounting for mediation through depression improvement were examined for statistical significance and magnitude using MPlus.ResultsIn this 6-week trial (N = 485), change scores from baseline to 6-weeks were significantly larger for both lurasidone treatment dosage groups versus placebo on the SDS total and all three SDS domain scores (p < 0.05). Through path analyses, lurasidone treatment predicted improvement in depression (β2 = -0.33, p = 0.009), subsequently predicting improvement in functional impairment (β3 = 0.70, p < 0.001; indirect effect = -0.23). The direct effect was of medium magnitude (β4 = -0.17, p = 0.04), indicating lurasidone had a significant and direct effect on improvement in functional impairment, after accounting for depression improvement.ConclusionsResults demonstrated statistically significant improvement in functioning among patients on lurasidone monotherapy compared to placebo. Improvement in functioning among patients on lurasidone was largely mediated through a reduction in depression symptoms, but lurasidone also had a medium and statistically significant independent direct effect in improving functioning.

Project description:BackgroundPatients with schizophrenia frequently switch between antipsychotics, underscoring the need to achieve and maintain important treatment outcomes such as health-related quality of life (HRQoL) following the switch. This analysis evaluated HRQoL changes among patients with schizophrenia switched from their current antipsychotic to lurasidone.MethodsStable but symptomatic outpatients with schizophrenia were switched from their current antipsychotic to lurasidone in a six-week, open-label trial. HRQoL was assessed using two validated patient-reported measures, the Personal Evaluation of Transitions in Treatment (PETiT) scale and the Short-Form 12 (SF-12). Total and domain scores (psychosocial function and adherence-related attitude) were assessed using the PETiT scale; patients' mental and physical component summary scores (MCS and PCS) were assessed using the SF-12. Changes in HRQoL from baseline to study endpoint were compared using ANCOVA, with baseline score, treatment, and pooled site as covariates. Changes were assessed among all patients and those switched from specific antipsychotics to lurasidone.ResultsThe analysis included 235 patients with data on the PETiT and SF-12 who had received ≥ 1 dose of lurasidone. Statistically significant improvements were observed from baseline to study endpoint on the PETiT total (mean change [SD]: 3.2 [8.5]) and psychosocial functioning (2.5 [6.9]) and adherence-related attitude (0.7 [2.6]) domain scores (all p ≤ 0.002). When examined by preswitch antipsychotic, significant improvements in PETiT total scores were observed in patients switched from quetiapine, risperidone, aripiprazole, and ziprasidone (all p < 0.03) but not olanzapine (p = 0.893). Improvements on the SF-12 MCS score were observed for all patients (mean change [SD]: 3.7 [11.5], p < 0.001) and for those switched from quetiapine or aripiprazole (both p < 0.03). The SF-12 PCS scores remained comparable to those at baseline in all patient groups.ConclusionsThese findings indicate that patients switching from other antipsychotics to lurasidone experienced statistically significant improvement of HRQoL, based on PETiT scores, within six weeks of treatment. Patient health status remained stable with respect to the SF-12 physical component and showed improvement on the mental component. Changes in HRQoL varied based on the antipsychotic used before switching to lurasidone.Trial registrationNCT01143077.

Project description:BACKGROUND:We examined the efficacy of olanzapine/fluoxetine combination (OFC) in improving health-related quality of life (QoL) in the treatment of bipolar depression in children and adolescents. METHODS:Patients aged 10-17 years with bipolar I disorder, depressed episode, baseline children's depression rating scale-revised (CDRS-R) total score ?40, Young Mania Rating Scale (YMRS) total score ?15, and YMRS-item 1 ? 2 were randomized to OFC (6/25-12/50 mg/day olanzapine/fluoxetine; n = 170) or placebo (n = 85) for up to 8 weeks of double-blind treatment. Patients and parents completed the revised KINDL questionnaire for measuring health-related QoL in children and adolescents (KINDL-R) at baseline and endpoint. The mean change in CDRS-R total and item scores were used to compare improvement in symptomatology in patients taking OFC and placebo. Tests were 2-sided using a Type I error cutoff of 0.05, and no adjustments for multiple comparisons were made. RESULTS:Baseline QoL as measured by the KINDL-R was substantially impaired relative to published norms for a healthy school-based sample. OFC-treated patients demonstrated an improvement over placebo at endpoint with respect to mean change from baseline in the patient-rated KINDL-R Self-esteem subscale score (p = 0.028), and in the parent KINDL-R ratings of emotional well-being (p = 0.020), Self-esteem (p = 0.030), and Family (p = 0.006). At endpoint, OFC-treated patients still had a lower QoL compared to the normative population. OFC showed significant improvement (p ? 0.05) versus placebo on the CDRS-R total score and on 7 of the 17 CDRS-R items. CONCLUSIONS:Patients aged 10-17 years with an acute episode of bipolar depression and their parents reported greater improvements (parents noticed improvements in more areas than did their offspring) on some aspects of QoL when treated with OFC compared with placebo. However, after 8 weeks of treatment, KINDL-R endpoint scores remained lower than those of the, presumably healthy, control population.

Project description:BackgroundLong-term improvement of health-related quality of life (HRQoL) in schizophrenia may improve adherence and reduce relapse and rehospitalization. This analysis examines long-term changes in HRQoL among patients with schizophrenia switched to lurasidone from other antipsychotics.MethodsPatients who completed an open-label 6-week switch study continued on lurasidone for an additional 24-weeks. HRQoL was measured using the self-reported Personal Evaluation of Transitions in Treatment (PETiT) scale and Short-Form 12 (SF-12) questionnaire. The PETiT assessed HRQoL via total and domain scores (adherence-related attitude and psychosocial functioning). The SF-12 assessed patients' mental and physical component summary scores (MCS and PCS). Mean changes from the initial baseline were calculated at extension baseline and extension endpoint using analysis of covariance models. Analyses were further stratified by prior antipsychotic medication and responder status; responders were defined as having a ≥20 % improvement in Positive and Negative Syndrome Scale during the first 6-weeks of treatment.ResultsThe analysis included 144 patients with PETIT or SF-12 data who received ≥1 dose of lurasidone. Mean (standard deviation) PETiT total score improved significantly from 34.9 (9.3) at baseline to 39.5 (8.9) at extension baseline and 39.1 (9.0) at extension endpoint, representing improvements of 4.5 (7.9) and 5.1 (7.2) points, respectively (both p < 0.001). Significant improvements in adherence-related attitude and psychosocial functioning were observed at extension baseline and extension endpoint (all p < 0.001). Improvement in SF-12 MCS score was observed at extension baseline and endpoint, and PCS score at extension endpoint (all p < 0.01). Patients who switched from quetiapine and aripiprazole showed significant improvement of PETiT total score and adherence-related attitude at extension baseline and extension endpoint. In addition, patients who switched from quetiapine, risperidone, aripiprazole, or ziprasidone showed significant improvement in MCS scores from baseline to extension endpoint. Responders to lurasidone demonstrated greater improvement in PETiT total, psychosocial functioning, and MCS scores at extension baseline than nonresponders.ConclusionsAfter switching to lurasidone, patients with schizophrenia experienced HRQoL improvements that were sustained for an additional 24 weeks of treatment. Further study is warranted to understand the implications of these improvements in terms of employment, adherence, relapse, and rehospitalization.Trial registrationClinical trials.gov identifier NCT01143090 (June 10th, 2010).

Project description:Abstract Background: Several atypical antipsychotics are approved to treat adolescent patients with schizophrenia. However, risk for antipsychotic-associated weight gain and metabolic dysfunction underscores the need to identify additional evidence-based treatments that are both efficacious and well tolerated in this vulnerable patient population. Lurasidone is an atypical antipsychotic agent that has demonstrated efficacy in the treatment of adults with schizophrenia in the dose range of 40–160?mg/d. The objective of this randomized, double-blind, placebo-controlled study was to evaluate the efficacy and safety of lurasidone in adolescent patients with schizophrenia. Methods: Adolescent patients (13–17 years old) who met DSM-IV-TR criteria for schizophrenia were randomized to 6 weeks of double-blind treatment with fixed-dose lurasidone 40?mg/d, 80?mg/d, or placebo. An MMRM analysis was performed to assess change from baseline to Week 6 on the primary (PANSS total score) outcome measure. An ANCOVA using an LOCF approach was performed to assess change from baseline on secondary endpoints: Pediatric Quality of Life Enjoyment and Satisfaction Questionnaire (PQ-LES-Q) and Children’s Global Assessment Scale (CGAS). Safety and tolerability assessments included adverse event reporting, weight, and laboratory measures. Results: A total of 327 patients (mean age = 15.4 years old) were randomized to receive lurasidone 40?mg/d (N = 108), 80?mg/d (N = 106) or placebo (N = 113). Performance on the PANSS total score at Week 6 demonstrated a placebo-adjusted LS mean improvement of ?8.0 (P < .001) for the 40?mg/d group and ?7.7 (P < .001) for the 80?mg/d group. Placebo-adjusted LS mean improvement at Week 6 on the PQ-LES-Q was 5.3 (P = .001) and 5.8 (P < .001) for the 40?mg/d and 80?mg/d groups, respectively; and, on the CGAS was 4.6 (P = .002) and 4.9 (P < .001) for the 40?mg/d and 80?mg/d groups, respectively. Study discontinuation due to adverse events was 8.0% in the placebo group and 3.7% in lurasidone treated patients. The most common adverse events (?5% in either lurasidone group and at least twice the rate of placebo) were: nausea, somnolence, akathisia, vomiting, and sedation. LS mean change in weight at week 6 for the lurasidone 40?mg/d, 80?mg/d, and placebo groups was 0.17?kg, 0.49?kg, and 0.05?kg, respectively. Median change at Week 6 (LOCF) in total cholesterol was ?4.0?mg/dL, ?2.0?mg/dL, and ?7.0?mg/dL, respectively; in triglycerides was ?2.0?mg/dL, 7.0?mg/dL, and ?2.0?mg/dL, respectively; and in glucose was 0.0?mg/dL, 1.0?mg/dL, and 0.0?mg/dL, respectively. Conclusion: Adolescent patients with schizophrenia treated with lurasidone demonstrated significant improvement in symptoms, quality of life, and function. Lurasidone was generally well tolerated and associated with minimal changes in weight and metabolic parameters. Sponsored by Sunovion Pharmaceuticals Inc. ClinicalTrials.gov identifier: NCT01911429
