Clinically relevant response and remission outcomes in cariprazine-treated patients with bipolar I disorder (original) (raw)

Cariprazine Treatment of Bipolar Depression: A Randomized Double-Blind Placebo-Controlled Phase 3 Study

American Journal of Psychiatry, 2019

Objective. Mixed presentations, defined by simultaneous occurrence of depressive and manic symptoms, are difficult to treat. Antidepressants, although commonly used, have weak evidence of efficacy and may increase risk of mood destabilization. The aim of this pooled post hoc analysis was to evaluate the efficacy of cariprazine in the treatment of bipolar depression with or without concurrent manic symptoms. Methods. Patients from 3 randomized, double-blind, placebo-controlled studies who met DSM-IV-TR or DSM-5 criteria for bipolar I disorder with a current major depressive episode were identified to have concurrent manic symptoms by baseline Young Mania Rating Scale total score ≥4. Efficacy was assessed in cariprazine 1.5 and 3 mg/day dose groups versus placebo; analyses included the least squares mean change from baseline to week 6 in Montgomery-Åsberg Depression Rating Scale (MADRS) total score. Results. Of 1383 patients randomized to treatment, 808 (58.4%) had concurrent manic symptoms. For patients with manic symptoms, mean reduction in MADRS total score from baseline to week 6 was significantly greater for both cariprazine 1.5 and 3 mg/day compared with placebo, with least squares mean differences (LSMDs) versus placebo of À2.5 (p = .0033) and À2.9 (p = .0010), respectively; for patients without manic symptoms, the LSMD was significant for 1.5 mg/day (À3.3; p = .0008), but not for 3 mg/day (À1.9; p = .0562). Conclusion. The results of this post hoc analysis suggest that cariprazine may be an appropriate treatment option for patients with bipolar I depression with or without manic symptoms, with higher doses potentially more effective in patients with manic symptoms.

Cariprazine in the treatment of acute mania in bipolar I disorder: A double-blind, placebo-controlled, Phase III trial

Journal of Affective Disorders, 2015

Background: This Phase III, randomized, double-blind, placebo-controlled study investigated the efficacy and tolerability of flexibly-dosed cariprazine in patients with acute manic or mixed episodes associated with bipolar I disorder. Methods: Patients were randomized to 3 weeks of double-blind treatment with cariprazine 3-12 mg/day (n ¼158) or placebo (n ¼154). The primary efficacy parameter was change from baseline to Week 3 in Young Mania Rating Scale (YMRS) total score. The secondary efficacy parameter was change from baseline to Week 3 in Clinical Global Impressions-Severity (CGI-S) score. Results: Mean change from baseline to Week 3 in YMRS total score was significantly greater for patients receiving cariprazine 3-12 mg/day versus placebo (P¼ 0.0004). Significant differences between groups in YMRS total score mean change were observed by Day 4 (first postbaseline assessment) and maintained throughout double-blind treatment (all assessments, Po 0.01). Cariprazine also demonstrated statistically significant superiority over placebo on YMRS response (Z 50% improvement: cariprazine, 58.9%; placebo, 44.1%; P ¼0.0097) and remission (YMRS total scorer12: cariprazine, 51.9%; placebo, 34.9%; P¼ 0.0025) and mean change in CGI-S (P¼ 0.0027) score and Positive and Negative Syndrome Scale (PANSS) (P¼ 0.0035) total score. The most common cariprazine-related (Z10% and twice placebo) treatment emergent adverse events (TEAEs) were akathisia, extrapyramidal disorder, tremor, dyspepsia, and vomiting. Mean change from baseline in metabolic parameters were generally small and similar between groups. Limitations: Lack of active comparator arm; short duration of study. Conclusion: In this study, cariprazine 3-12 mg/day was effective and generally well tolerated in the treatment of manic and mixed episodes associated with bipolar I disorder.

An 8-Week Randomized, Double-Blind, Placebo-Controlled Evaluation of the Safety and Efficacy of Cariprazine in Patients With Bipolar I Depression

American Journal of Psychiatry, 2016

The authors evaluated the efficacy, safety, and tolerability of cariprazine, an atypical antipsychotic candidate, in adult patients with acute bipolar I depression. Method: This was an 8-week multinational, multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study in adult patients with bipolar I disorder experiencing a current major depressive episode. Patients were randomly assigned (1:1:1:1) to receive placebo or cariprazine at 0.75, 1.5, or 3.0 mg/day. The primary and secondary efficacy parameters were change from baseline to week 6 on the Montgomery-Åsberg Depression Rating Scale (MADRS) and the Clinical Global Impressions severity subscale (CGI-S), respectively, analyzed using a mixed-effects model for repeated measures on the modified intent-to-treat population. Results: The intent-to-treat population comprised 571 patients (141 in the placebo group and 140, 145, and 145 in the cariprazine 0.75-, 1.5-, and 3.0-mg/day groups). Cariprazine at 1.5 mg/day showed significantly greater improvement on MADRS total score change from baseline to week 6 compared with placebo; the least squares mean difference was 24.0 (95% CI=26.3, 21.6; significant after adjustment for multiple comparisons). Cariprazine at 3.0 mg/day showed greater MADRS score reduction than placebo (22.5, 95% CI=24.9, 20.1; not significant when adjusted for multiple comparisons). The 0.75 mg/day dosage was similar to placebo. A similar pattern for significance was observed on the CGI-S (1.5 mg/day: least squares mean difference=20.4, 95% CI=20.6, 20.1; 3.0 mg/day: 20.3, 95% CI=20.5, 20.0). The most common adverse events ($10%) in cariprazine-treated patients were akathisia and insomnia; weight gain was slightly higher with cariprazine than with placebo. Conclusions: Cariprazine at 1.5 mg/day demonstrated consistent efficacy compared with placebo across outcomes and was generally well tolerated, suggesting efficacy for the treatment of bipolar I depression.

Efficacy and Safety of Low- and High-Dose Cariprazine in Acute and Mixed Mania Associated With Bipolar I Disorder

The Journal of Clinical Psychiatry, 2014

Objective: This phase 3 trial evaluated the efficacy, safety, and tolerability of low-and high-dose cariprazine in patients meeting DSM-IV-TR criteria for acute manic or mixed episodes associated with bipolar I disorder. Method: This multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed/flexible-dose study was conducted from February 2010 to December 2011. Patients were randomly assigned to placebo, cariprazine 3-6 mg/d, or cariprazine 6-12 mg/d for 3 weeks of double-blind treatment. Primary and secondary efficacy parameters were change from baseline to week 3 in Young Mania Rating Scale (YMRS) total score and Clinical Global Impressions-Severity of Illness (CGI-S) score, respectively. Post hoc analysis examined change from baseline to week 3 in YMRS single items. Results: A total of 497 patients were randomized; 74% completed the study. The least squares mean difference (LSMD) for change from baseline to week 3 in YMRS total score was statistically significant in favor of both cariprazine groups versus placebo (LSMD [95% CI]: 3-6 mg/d, −6.1 [−8.4 to −3.8]; 6-12 mg/d, −5.9 [−8.2, −3.6]; P < .001 [both]). Both cariprazine treatment groups showed statistically significant superiority to placebo on all 11 YMRS single items (all comparisons, P < .05). Change from baseline in CGI-S scores was statistically significantly greater in both cariprazine groups compared with placebo (LSMD [95% CI]: 3-6 mg/d, −0.6 [−0.9 to −0.4]; 6-12 mg/d, −0.6 [−0.9 to −0.3]; P < .001 [both]). The most common (≥ 5% and twice the rate of placebo) treatment-related adverse events for cariprazine were akathisia (both groups) and nausea, constipation, and tremor (6-12 mg/d only). Conclusions: Results of this study demonstrated that both low-and high-dose cariprazine were more effective than placebo in the treatment of acute manic or mixed episodes associated with bipolar I disorder. Cariprazine was generally well tolerated, although the incidence of akathisia was greater with cariprazine than with placebo.

The efficacy of cariprazine on function in patients with bipolar depression: a post hoc analysis of a randomized controlled trial

2021

Introduction: Individuals with bipolar depression often experience functional impairment that interferes with recovery. These analyses examined the effects of cariprazine on functional outcomes in patients with bipolar I disorder. Methods: Prespecified analyses of data from a randomized, double-blind, placebo-controlled pivotal trial of cariprazine in bipolar I depression (NCT01396447) evaluated mean changes from baseline to week 8 in Functional Assessment Short Test (FAST) total score. Post hoc analyses with no adjustment for multiplicity evaluated FAST subscale scores, functional recovery and remission (FAST total score 11 and 20, respectively), and 30% or 50% improvement from baseline. Results: There were 393 patients with bipolar I disorder (placebo ¼ 132; cariprazine: 1.5 mg/d ¼ 135, 3 mg/d ¼ 126) in the FAST analysis population. Statistically significant differences were noted for cariprazine 1.5 mg/d versus placebo in mean change from baseline in FAST total score (p<.01) and on 5 of 6 subscale scores (p<.05); cariprazine 3 mg/d was significantly different than placebo on the Interpersonal Relationship subscale (p<.05). Rates of functional remission and recovery, and 30% or 50% improvement were significantly greater for cariprazine 1.5 mg/d versus placebo (p<.05 all); the percentage of patients with 30% improvement was significantly different for cariprazine 3 mg/d versus placebo (p<.05). Conclusion: At week 8, statistically significant improvements in FAST outcomes were observed for cariprazine versus placebo in patients with bipolar I depression; more consistent results were noted for 1.5 mg/d than 3 mg/d. In addition to improving bipolar depression symptoms, these results suggest that cariprazine may improve functional outcomes.

Effect of cariprazine across the symptoms of mania in bipolar I disorder: Analyses of pooled data from phase II/III trials

European Neuropsychopharmacology, 2015

Bipolar I disorder is a chronic disorder characterized by episodic recurrences of mania, depression, and mixed affective states interspersed with periods of full or partial remission; subsyndromal residual symptoms between episodes are common and disabling. Cariprazine, an atypical antipsychotic, is a potent dopamine D 3 and D 2 receptor partial agonist with preferential binding to D 3 receptors. Post-hoc analyses of pooled data from 3 positive trials were conducted to evaluate the effect of cariprazine 3-12 mg/d on the symptoms of mania in inpatients (18-65 years) with bipolar I disorder and a current manic episode. Analyses were based on the pooled intent-to-treat (ITT) population (placebo =429; cariprazine =608). Mean change from baseline to the end of treatment on individual Young Mania Rating Scale (YMRS) items was analysed using a mixed-effects model for repeated measures (MMRM); categorical symptom severity shifts were analysed using logistic regression. Statistically significant improvement in mean change was seen for cariprazine versus placebo on all 11 YMRS items (po0.0001); significantly more cariprazine-versus placebo-treated patients had mild/no symptoms at the end of treatment on 11 YMRS items (po0.0001) and concurrently on the 4 YMRS core symptoms (irritability, speech, content, and disruptive-aggressive behaviour) (po0.0001). Significantly more cariprazine-versus placebo-treated patients shifted from a Moderate/Worse or Marked/Worse Symptoms categories to Mild/No Symptoms on all 11 (po0.0001) and 9 of 11 YMRS items (po0.05), respectively. Results suggest that cariprazine

Tolerability of cariprazine in the treatment of acute bipolar I mania: A pooled post hoc analysis of 3 phase II/III studies

Journal of affective disorders, 2017

Atypical antipsychotics have broad-spectrum efficacy against core symptoms of acute mania/mixed states in bipolar disorder; however, they are associated with clinically significant adverse effects (AEs). This post hoc analysis evaluated the safety and tolerability of the atypical antipsychotic cariprazine in the treatment of adult patients with acute manic/mixed episodes of bipolar I disorder. Data were taken from three 3-week randomized, double-blind, placebo-controlled, flexible-dose trials of cariprazine 3-12mg/d. Patient subgroups categorized by modal daily dose (3-6mg/d; 9-12mg/d) were used to assess dose response. The pooled safety population comprised 1065 patients (placebo=442; cariprazine 3-6mg/d=263; cariprazine 9-12mg/d=360). More cariprazine- than placebo-treated patients reported double-blind treatment-emergent AEs; the overall AE incidence was similar among cariprazine-dose groups. AEs reported in ≥5% of cariprazine patients overall with at least twice the incidence of...

Global improvement with cariprazine in the treatment of bipolar I disorder and schizophrenia: A pooled post hoc analysis

International journal of clinical practice, 2017

Global rating scale measures are useful for assessing the clinical relevance of patient change. Cariprazine, a dopamine D3 and D2 receptor partial agonist, is FDA-approved for the adult treatment of acute manic/mixed episodes of bipolar I disorder and schizophrenia. Post hoc evaluations of Clinical Global Impressions-Severity (CGI-S) scores from the cariprazine pivotal trials in both indications were conducted. Data from 3 bipolar mania and 3 schizophrenia trials were pooled by indication (bipolar disorder = 1033; schizophrenia = 1466). Cariprazine- and placebo-treated patients were categorised by baseline CGI-S scores; the proportion of patients who improved from more severe categories at baseline to less severe categories at end-point was evaluated using a logistic regression model. Correlations between Young Mania Rating Scale and Positive and Negative Syndrome Scale total score changes and category shifts were also evaluated. In both disease states, more cariprazine- than placeb...
