The Effect of Lurasidone on Anxiety Symptoms in Patients With Bipolar Depression: A Post Hoc Analysis.

Objective: To assess the effects of lurasidone on anxiety symptoms and sleep disruption, and their moderating and mediating roles on treatment response in bipolar depression.Methods: This post hoc analysis included pooled data from 2 previously published 6-week placebo-controlled trials of lurasidone for bipolar I depression conducted between April 2009 and February 2012. Hamilton Anxiety Rating Scale (HAM-A) "psychic anxiety" (items 1-6, 14) and "somatic anxiety" (items 7-13) subscores were calculated. Functional outcome was assessed by the Sheehan Disability Scale.Results: All subjects (n = 824) had at least 1 psychic anxiety and 729 (88.5%) had at least 1 somatic anxiety symptom at baseline. 594 subjects (72.1%) experienced baseline sleep disturbance. Lurasidone, as monotherapy (20-60 mg/d and 80-120 mg/d pooled dose groups vs placebo) and adjunctive therapy (20 to 120 mg/d flexibly dosed vs placebo) with lithium or valproate, significantly reduced HAM-A psychic anxiety (-4.82 vs -2.97, P < .001, monotherapy; -5.56 vs -4.26, P = .009, adjunctive therapy) and somatic anxiety (-1.89 vs -1.37, P = .048, monotherapy; -2.22 vs -1.47, P = .006, adjunctive therapy) subcomponents. Improvement in anxiety symptoms mediated reduction in depressive symptoms and functional impairment. Decrease in sleep at baseline predicted change in anxiety symptoms with lurasidone treatment at week 6.Conclusions: Lurasidone was superior to placebo in reducing psychic and somatic anxiety in the short-term treatment of bipolar depression. Improvement in depressive symptoms and reduction in functional impairment were associated with reduction in anxiety symptoms moderated by baseline sleep disturbance during lurasidone treatment.Trial Registration: ClinicalTrials.gov identifiers: NCT00868699 and NCT00868452.

Sleep Disturbance, Irritability, and Response to Lurasidone Treatment in Children and Adolescents with Bipolar Depression.

BACKGROUND: The presence of mixed (subsyndromal hypomanic) symptoms may influence treatment outcomes in pediatric bipolar depression. This post-hoc analysis investigated "bridge" symptoms that have cross-sectional and predictive associations with depressive and manic symptom clusters in youth with bipolar depression. METHODS: The moderating effects of these bridge symptoms on the response to flexibly dosed lurasidone 20-80 mg/d compared to placebo treatment was analyzed in children and adolescents with bipolar I depression in a six-week, placebo-controlled, double-blind study followed by a 2-year, openlabel extension study of lurasidone. RESULTS: Sleep disturbances, assessed by "difficulty with sleep" (Children's Depression Rating Scale, Revised [CDRS-R] item 4) and "decreased need for sleep" (Young Mania Rating Scale [YMRS] item 4), and "irritability" (CDRS-R item-8, YMRS item 5) were identified as "bridge" symptoms and found to have replicable causal associations with depressive (CDRS-R total) and manic symptom clusters (YMRS total) at baseline and week-6. A greater improvement in overall depression severity at week 6 with lurasidone (vs. placebo) treatment was observed in the presence (vs. absence) of decreased need for sleep at study baseline, mediated in part by significant reductions from study baseline in decreased need for sleep and manic symptom severity. The absence of sleep disturbance and irritability in patients at open-label extension study baseline was associated with higher rates of sustained recovery (symptomatic and functional remission) over 6 months compared to patients with those symptoms at baseline (68% vs. 50%, Number Needed to Treat=6). CONCLUSION: Our findings suggest that sleep disturbance and irritability are cardinal symptoms that "bridge" between depressive and manic symptom clusters and influence treatment outcomes in youth with bipolar depression.

Development of the Social Motor Function Classification System for Children with Autism Spectrum Disorders: A Psychometric Study.

To examine reliability and validity of the new Social Motor Function Classification System for Children with Autism Spectrum Disorders (SMFCS-ASD). The SMFCS-ASD reliability was examined on 25 children (62.4 months SD 7.8) with ASD among six physical therapists. The validity study involved 1001 children (57.0 months, SD 9.9) with ASD using the gross motor scale (GMS) of the Peabody Developmental Motor Scales (PDMS-2). The indices of agreement and reliability across six examiners were moderate to substantial (Cohen's κ ≤ 0.65 and ICC > 0.90, all p < 0.001). The SMFCS-ASD was significantly correlated with the GMS of PDMS-2 (all rho from 0.61 to 0.76, p < 0.001). The SMFCS-ASD was reliable and significantly correlated with the GMS of the PDMS-2.

Major depressive disorder with mixed features and treatment response to lurasidone: A symptom network model.

BACKGROUND: To investigate the symptom network structure of major depressive disorder (MDD) with mixed features and implications for treatment. METHODS: In this post-hoc analysis of a previously reported randomized trial, patients meeting DSM-IV-TR criteria for MDD presenting with two or three manic symptoms (DSM-5 mixed features specifier) were randomized to 6 weeks of double-blind treatment with lurasidone 20-60 mg/d (N = 109) or placebo (N = 100). The network structure of symptoms at baseline and their treatment moderating effects were investigated. RESULTS: Network analyses showed that both ``elevated mood'' (YMRS item 1) and ``increased motor activity-energy'' (YMRS item 2) were associated with ``sleep disturbance'' ("bridge" symptom) and the depressive symptom cluster. Presence of both "elevated mood" and "increased motor activity-energy" at baseline predicted significantly less improvement in MADRS and CGI-S score at week 6 with lurasidone (vs. placebo) compared to patients without these manic symptoms at baseline. The network model also showed "rapid/pressured speech" (YMRS item 6) at baseline predicted improvement in both manic and depressive symptoms with lurasidone vs. placebo treatment. LIMITATIONS: This was a post-hoc analysis where findings need to be confirmed by prospective controlled studies. CONCLUSIONS: This post-hoc analysis describes the symptom network structure of MDD with mixed features in a patient sample at study baseline. Specific manic symptoms were found to be linked to sleep disturbance (characterized as a "bridge" symptom), which in turn linked the manic and depressive symptom clusters. The presence (vs. absence) of the specific manic symptoms we identified moderated the antidepressant and antimanic effects of lurasidone in the treatment of MDD with mixed (subthreshold hypomanic) features.

Association of C-reactive protein and metabolic risk with cognitive effects of lurasidone in patients with schizophrenia.

BACKGROUND: Accumulating evidence has implicated insulin resistance and inflammation in the pathophysiology of cognitive impairments associated with neuropsychiatric disorders. This post-hoc analysis based on a placebo-controlled trial investigated the effect of inflammation (indexed by CRP) and metabolic risk factors on cognitive performance in patients with schizophrenia treated with lurasidone. METHODS: Acutely exacerbated patients with schizophrenia were randomized to lurasidone (80 or 160 mg/day), quetiapine XR 600 mg/day, or placebo. A wide range CRP test and a cognitive assessment using the CogState computerized battery were performed at baseline and week 6 study endpoint. Associations between log-transformed CRP, high density lipoprotein (HDL), homeostatic model assessment of insulin resistance (HOMA-IR) and treatment response were evaluated. RESULTS: CRP combined with HDL, triglyceride-to-HDL (TG/HDL) ratio, or HOMA-IR at study baseline were significant moderators of the improvement in cognitive performance associated with lurasidone 160 mg/day (vs. placebo) treatment (p < .05). Greater placebo-corrected treatment effect size on the CogState composite score was observed for patients in the lurasidone 160 mg/day treatment group who had either low CRP and high HDL (d = 0.43), or low CRP and low HOMA-IR (d = 0.46). Interactive relationships between CRP, HDL, TG/HDL, HOMA-IR and the antipsychotic efficacy of lurasidone or quetiapine XR were not significant. There were no significant associations between antipsychotic treatment and changes in CRP level at study endpoint. CONCLUSIONS: Findings of this post-hoc analysis based on a placebo-controlled trial in patients with schizophrenia suggest that baseline CRP level combined with measures of metabolic risk significantly moderated the improvement in cognitive performance associated with lurasidone 160 mg/day (vs. placebo) treatment. Our findings underscore the importance of maintaining a low metabolic risk profile in patients with schizophrenia.

Lurasidone in Children and Adolescents with Bipolar Depression Presenting with Mixed (Subsyndromal Hypomanic) Features: Post Hoc Analysis of a Randomized Placebo-Controlled Trial.

Objectives: To evaluate the efficacy and safety of lurasidone in the treatment of children and adolescents with bipolar depression presenting with mixed (subsyndromal hypomanic) features. Methods: Patients, 10-17 years of age, with a Diagnostic and Statistical Manual of Mental Disorders, 5th ed. (DSM-5), diagnosis of bipolar I depression were randomized to 6 weeks of double-blind treatment with once-daily flexible doses of lurasidone 20-80 mg or placebo. The presence of mixed (subsyndromal hypomanic) features in this pediatric bipolar depression trial was defined as a Young Mania Rating Scale score of 5 or greater at study baseline. Key efficacy measures included change from baseline to week 6 in the Children's Depression Rating Scale-Revised (CDRS-R) score (primary endpoint) and Clinical Global Impressions-Bipolar Severity (CGI-BP-S) score, using a mixed model for repeated measures analysis. Results: At baseline, subsyndromal hypomanic features were present in 54.2% of patients. Treatment with lurasidone (vs. placebo) was associated with significantly greater reductions in CDRS-R scores at week 6, independent of the presence (-21.5 vs. -15.9, p < 0.01; effect size d = 0.43) or absence (-20.5 vs. -14.9, p < 0.01; d = 0.44) of subsyndromal hypomanic features. Likewise, lurasidone (vs. placebo) was associated with significantly greater reductions in CGI-BP-S scores at week 6, independent of the presence (-1.6 vs. -1.1, p < 0.001, d = 0.51) or absence (-1.3 vs. -1.0, p = 0.05; d = 0.31) of these subsyndromal hypomanic features. Rates of protocol-defined treatment-emergent hypomania or mania were similar for lurasidone and placebo in patients with (lurasidone 8.2% vs. placebo 9.0%) or without subsyndromal hypomanic features (lurasidone 1.3% vs. placebo 3.7%). Conclusions: In this post hoc analysis of a randomized placebo-controlled trial, lurasidone was found to be efficacious in the treatment of child and adolescent patients with bipolar depression who presented with mixed (subsyndromal hypomanic) features. No differences in safety profile, including the risk of treatment-emergent mania, were observed in patients with or without subsyndromal hypomanic features in this study.

Best (but oft-forgotten) practices: identifying and accounting for regression to the mean in nutrition and obesity research.

BACKGROUND: Regression to the mean (RTM) is a statistical phenomenon where initial measurements of a variable in a nonrandom sample at the extreme ends of a distribution tend to be closer to the mean upon a second measurement. Unfortunately, failing to account for the effects of RTM can lead to incorrect conclusions on the observed mean difference between the 2 repeated measurements in a nonrandom sample that is preferentially selected for deviating from the population mean of the measured variable in a particular direction. Study designs that are susceptible to misattributing RTM as intervention effects have been prevalent in nutrition and obesity research. This field often conducts secondary analyses of existing intervention data or evaluates intervention effects in those most at risk (i.e., those with observations at the extreme ends of a distribution). OBJECTIVES: To provide best practices to avoid unsubstantiated conclusions as a result of ignoring RTM in nutrition and obesity research. METHODS: We outlined best practices for identifying whether RTM is likely to be leading to biased inferences, using a flowchart that is available as a web-based app at https://dustyturner.shinyapps.io/DecisionTreeMeanRegression/. We also provided multiple methods to quantify the degree of RTM. RESULTS: Investigators can adjust analyses to include the RTM effect, thereby plausibly removing its biasing influence on estimating the true intervention effect. CONCLUSIONS: The identification of RTM and implementation of proper statistical practices will help advance the field by improving scientific rigor and the accuracy of conclusions. This trial was registered at clinicaltrials.gov as NCT00427193.

C-reactive protein and response to lurasidone treatment in children and adolescents with bipolar I depression: Results from a placebo-controlled trial.

This study sought to investigate associations between levels of high-sensitivity c-reactive protein (hsCRP) prior to treatment and change in depressive symptoms and cognition in a short-term, double-blind, placebo-controlled study of lurasidone in children and adolescents with bipolar I depression. Patients 10-17 years of age with a DSM-5 diagnosis of bipolar I depression were randomized to 6 weeks of double-blind treatment with flexibly dosed lurasidone (20-80 mg/day) (n = 173) or placebo (n = 170). The primary efficacy measure was change from baseline to week 6 in the Children's Depression Rating Scale, Revised (CDRS-R). Treatment response was defined as 50% or greater improvement on the CDRS-R from baseline to week 6. Cognitive function was evaluated with the computerized Brief Cogstate Battery at baseline and week 6. Analyses were adjusted for baseline BMI, as well as age. HsCRP was evaluated as a logarithmically transformed continuous variable and as a categorical variable dichotomized into lower (<1 mg/L) and higher (≥1 mg/L) subgroups. A significant interaction was found between baseline hsCRP and treatment group for change in CDRS-R score at study endpoint, with larger placebo-corrected effect sizes for lurasidone in the higher baseline hsCRP group (≥1 mg/L). A significant BMI-by-hsCRP-by-treatment interaction was found for response rate with higher baseline hsCRP levels associated with greater antidepressant response to lurasidone (vs. placebo) in the normal BMI range subgroup (NNT = 2 in higher hsCRP vs. NNT = 5 in lower hsCRP groups) but not in the overweight/obese patients (NNT = 6 in higher hsCRP vs. NNT = 5 in lower hsCRP). Similarly, a significant interaction effect was observed for the combination of hsCRP and BMI on the procognitive effect of lurasidone, with higher baseline hsCRP levels being associated with improvement in cognitive function for lurasidone (vs placebo) in the normal BMI range subgroup but not in overweight/obese patients. These results suggest that young patients with bipolar depression with normal weight and higher levels of pre-treatment CRP may show a greater placebo-adjusted improvement in depressive symptoms and cognitive performance when treated with lurasidone. If these findings are confirmed in future prospective studies, CRP and BMI may prove to be useful diagnostic and predictive biomarkers in the treatment with lurasidone of children and adolescents with bipolar depression.

Neglecting regression to the mean continues to lead to unwarranted conclusions: Letter regarding "The magnitude of weight loss induced by metformin is independently associated with BMI at baseline in newly diagnosed type 2 diabetes: Post-hoc analysis from data of a phase IV open-labeled trial".

As the prevalence of type 2 diabetes mellitus and obesity increases worldwide, scientifically rigorous research is needed in this field to determine effective interventions for the prevention and treatment of these chronic diseases. In a recent study published in this journal, Zhou et al. conclude that metformin, a drug used for treatment of type 2 diabetes mellitus, can be used effectively for weight loss, and that this effect is even more pronounced in individuals who weigh more at baseline. Unfortunately, we believe these results to be due to the regression to the mean (RTM) phenomenon, which weakens the causal inference proposed in this study. The conclusions of Zhou et al. that metformin is an effective strategy for weight loss in individuals with type 2 diabetes mellitus are not substantiated due to the lack of a control group and failure to consider other factors that may have confounded these results.

Associations of the serotonin transporter promoter polymorphism (5-HTTLPR) with bipolar disorder and treatment response: A systematic review and meta-analysis.

BACKGROUND: Associations of the serotonin transporter promoter polymorphism (5-HTTLPR) with bipolar disorder (BPD) and treatment response in bipolar patients were not conclusive. This study not only assessed the association between the 5-HTTLPR and BPD with accumulating relevant studies, but also in the first time evaluated the effect of the 5-HTTLPR on both anti-depressive and anti-manic treatment responses in bipolar patients. METHODS: PubMed, Embase, PsycINFO, Cochrane Library and Cochrane Control Trials databases were systematically searched before February 2017. This meta-analysis followed the PRISMA guidelines. RESULTS: A total of 32 population-based studies (5567 cases and 6993 controls) and 9 family-based studies (837 trios) were finally screened out and statistically joined into a single meta-analysis that revealed an association between S allele and an increased risk of BPD (OR = 1.06, p = .038). Pooled analysis of the 32 population-based studies indicated an association of S-carrier genotypes with an increased risk of BPD (OR = 1.10, p = .029). Meanwhile, the association remained significant in Caucasians (OR = 1.15, p = .004), which could provide an enough power (88%) to detect a significant association. Regarding the treatment response studies, 6 studies reporting the relationship of the 5-HTTLPR in anti-depressive remission rate (1034 patients) and 7 studies reporting in response rate (1098 patients) were included for pooled analyses. We observed a significant association of S-carrier genotypes with a reduced anti-depressive remission rate (OR = 0.64, p = .006) but not with anti-depressive response rate. The association between the 5-HTTLPR with anti-manic response rate was not observed in the included 6 studies (676 patients). CONCLUSIONS: The present study supported the presence of a marginal but detectable effect of the 5-HTTLPR on susceptibility to BPD. Moreover, the detected association in Caucasian was statistically reliable. Besides, the 5-HTTLPR was identified as a useful predictor for anti-depressive remission but not for anti-depressive or anti-manic response.

Does relapse contribute to treatment resistance? Antipsychotic response in first- vs. second-episode schizophrenia.

Although some studies have suggested that relapse may be associated with antipsychotic treatment resistance in schizophrenia, the number and quality of studies is limited. The current analysis included patients with a diagnosis of first-episode schizophrenia or schizoaffective disorder who met the following criteria: (1) referral to the First-Episode Psychosis Program between 2003 and 2013; (2) treatment with an oral second-generation antipsychotic according to a standardized treatment algorithm; (3) positive symptom remission; (4) subsequent relapse (i.e., second episode) in association with non-adherence; and (5) reintroduction of antipsychotic treatment with the same agent used to achieve response in the first episode. The following outcomes were used as an index of antipsychotic treatment response: changes in the brief psychiatric rating scale (BPRS) total and positive symptom scores and number of patients who achieved positive symptom remission and 20 and 50% response. A total of 130 patients were included in the analyses. Although all patients took the same antipsychotic in both episodes, there were significant episode-by-time interactions for all outcomes of antipsychotic treatment response over 1 year in favor of the first episode compared to the second episode (50% response rate: 48.7 vs. 10.4% at week 7; 88.2 vs. 27.8% at week 27, respectively). Although antipsychotic doses in the second episode were significantly higher than those in the first episode, results remained unchanged after adjusting for antipsychotic dose. The present findings suggest that antipsychotic treatment response is reduced or delayed in the face of relapse following effective treatment of the first episode of schizophrenia.

Associations of Homer Scaffolding Protein 1 gene and psychological correlates with suicide attempts in Chinese: A pilot study of multifactorial risk model.

BACKGROUND: Suicide is a fatal outcome for subjects with mental ill-health. Genetic factors and psychological correlates are believed to contribute to the risk of suicide attempts (SA), whereas both factors are reported to exert a small effect. This study therefore tried to investigate if combination of the two aspects can enhance the explanation of variance in SA. METHODS: A common variant rs7713917 in HOMER1 gene was genotyped for 333 Chinese psychiatric patients with or without SA. Multifactorial risk models comprised of this variant and psychological correlates were identified by logistic regression analysis (LRA) and Multifactor Dimensionality Reduction (MDR) method separately, and then evaluated for their performance by biostatistical methods. RESULTS: An association of A-carrier genotypes in rs7713917 with an increased risk of SA was observed (OR = 1.79, 95% CI = 1.08-2.98). Although with a medium effect size, this variant alone could only explain 1.9% variance of SA. Interestingly, this study was the first time to show that the association of the rs7713917 and SA was significantly mediated by the NEO conscientiousness (NEOC) dimension (p-value = 0.002), with a greater genetic effect observed in subjects with a low NEO-C level (OR = 2.89, 95% CI = 1.16-7.18) but not in subjects with an average or high level. Upon the LRA method, the multifactorial risk model constituted of the two interacted factors and their interaction effect could explain up to 17.0% variance, which was almost 9-fold higher than the one explained by the rs7713917 alone. Furthermore, this model owned a higher effectiveness than the three models identified by the MDR method (p-value < 0.0007). CONCLUSIONS: The present study identified an effective multifactorial risk model, in which the combination of the HOMER1 variant and the NEO-C dimension could enhance explanation of the variance of SA in Chinese. This pilot study may provide a novel avenue to investigate the pathogenesis of SA in psychiatric patients.

C-reactive protein and response to lurasidone in patients with bipolar depression.

Prior studies suggest that the inflammatory biomarker c-reactive protein (CRP) holds promise for predicting antidepressant response in patients with major depressive disorder. The objective of this study was to evaluate whether CRP might similarly predict antidepressant responses to lurasidone in patients with bipolar I depression. Serum CRP concentration was measured prior to, and following, 6 weeks of treatment in 485 outpatients with bipolar I depression. Patients were randomized to receive monotherapy with lurasidone 20-60 mg/day (N = 161), lurasidone 80-120 mg/day (N = 162) or placebo (N = 162). CRP was assessed using the wide-range CRP assay (wr-CRP). The primary efficacy endpoint was change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale (MADRS) score. Mixed models and statistical interaction tests were applied to investigate the moderating effects of pre-treatment wr-CRP on clinical endpoints. CRP was evaluated as a log-transformed continuous variable and by clinically-relevant cut-points. Increasing pre-treatment wr-CRP level predicted a larger overall antidepressant response to lurasidone, as well as an increased response for a number of individual depressive symptoms. These moderating effects of pre-treatment wr-CRP remained significant after adjustment for potential confounds (e.g. baseline BMI and weight change). Treatment with lurasidone did not affect serum concentrations of CRP compared to placebo during the study. Elevated CRP level prior to treatment was associated with an enhanced clinical response to lurasidone in patients with bipolar I depression. If confirmed in future studies, CRP may represent a clinically useful diagnostic and predictive biomarker supporting a precision medicine approach to the treatment of bipolar depression.

Remission and recovery associated with lurasidone in the treatment of major depressive disorder with subthreshold hypomanic symptoms (mixed features): post-hoc analysis of a randomized, placebo-controlled study with longer-term extension.

OBJECTIVE: This post-hoc analysis assessed rates of symptomatic and functional remission, as well as recovery (combination of symptomatic and functional remission), in patients treated with lurasidone for major depressive disorder (MDD) associated with subthreshold hypomanic symptoms (mixed features). METHOD: Patients with MDD plus two or three manic symptoms (defined as per the DSM-5 mixed-features specifier) were randomly assigned to flexible-dose lurasidone 20-60 mg/day (n=109) or placebo (n=100) for 6 weeks, followed by a 3-month open-label, flexible-dose extension study for U.S. sites only (n=48). Cross-sectional recovery was defined as the presence of both symptomatic remission (Montgomery-Åsberg Depression Rating Scale score ≤ 12) and functional remission (all Sheehan Disability Scale [SDS] domain scores ≤3) at week 6, and at both months 1 and 3 of the extension study ("sustained recovery"). RESULTS: A significantly higher proportion of lurasidone-treated patients (31.3%) achieved recovery (assessed cross-sectionally) compared to placebo (12.2%, p=0.002) at week 6. The number of manic symptoms at baseline moderated the effect size for attaining cross-sectional recovery for lurasidone treatment (vs. placebo) (p=0.028). Sustained recovery rates were higher in patients initially treated with lurasidone (20.8%) versus placebo (12.5%). CONCLUSIONS: In this post-hoc analysis of a placebo-controlled study with open-label extension that involved patients with MDD and mixed features, lurasidone was found to significantly improve the rate of recovery at 6 weeks (vs. placebo) that was sustained at month 3 of the extension study. The presence of two (as opposed to three) manic symptoms moderated recovery at the acute study endpoint.

Insight and Treatment Outcomes in Schizophrenia: Post-hoc Analysis of a Long-term, Double-blind Study Comparing Lurasidone and Quetiapine XR.

Objective: The objective of this post-hoc analysis was to evaluate the effect of lurasidone and quetiapine extended-release (XR) on insight and judgment and assess the longitudinal relationships between improvement in insight and cognitive performance, functional capacity, quality of well-being, and depressive symptoms in patients with schizophrenia. Design: Clinically unstable patients with schizophrenia (N=488) were randomized to once-daily, fixed-dose treatment with lurasidone 80mg, lurasidone 160mg, quetiapine XR 600mg, or placebo, followed by a long-term, double-blind, flexible-dose continuation study involving these agents. Results: Significantly greater improvement in insight and judgment (assessed by the Positive and Negative Syndrome Scale G12 item) for the lurasidone and quetiapine XR groups, compared to the placebo group, was observed at Week 6. Over a subsequent six-month continuation period, the flexible dose lurasidone group showed significantly greater improvement in insight from acute phase baseline compared to the flexible-dose quetiapine XR group (QXR-QXR) (p=0.032). Improvement in insight was significantly correlated with improvement in cognition (p=0.014), functional capacity (p=0.006, UPSA-B), quality of well-being (p=0.033, QWB), and depressive symptoms (p=0.05, Montgomery-Åsberg Depression Rating Scale [MADRS] score) across treatment groups and study periods. Conclusion: In this post-hoc analysis, flexibly dosed lurasidone 40 to 160mg/d was found to be associated with significantly greater improvement in insight compared to flexibly dosed quetiapine XR 200 to 800mg/d over long-term treatment in patients with schizophrenia. Across treatment groups, improvement in insight and judgment was significantly associated with improvement in cognition, functional capacity, quality of well-being, and depressive symptoms over time.
