AbbVie’s cariprazine met primary endpoint in Phase 3 study
AbbVie (ABBV) announced top-line results from two Phase 3 clinical trials, Study 3111-301-001 and Study 3111-302-001, evaluating the efficacy and safety of cariprazine as an adjunctive treatment for patients with major depressive disorder.
Cariprazine, sold under the brand names Vraylar in the United States and Reagila in the European Union, is an atypical antipsychotic which is used in the treatment of schizophrenia, bipolar mania, and bipolar depression.
In Study 3111-301-001, cariprazine showed a statistically significant change from baseline to week six in the Montgomery-Asberg Depression Rating Scale total score compared with placebo.
The Montgomery–Asberg Depression Rating Scale (MADRS) is a ten-item diagnostic questionnaire which psychiatrists use to measure the severity of depressive episodes in patients with mood disorders.
Patients treated with cariprazine at 1.5 mg/day achieved improved MADRS total score at week six compared to placebo.
Patients treated with cariprazine at 3.0 mg/day demonstrated improvement in MADRS total score at week six over placebo but did not meet statistical significance.
In Study 3111-302-001, cariprazine demonstrated numerical improvement in depressive symptoms from baseline to week six in MADRS total score compared with placebo but did not meet its primary endpoint for either the 1.5 mg/day or 3.0 mg/day dose.
In a previously published Phase 2/3 registration-enabling study, RGH-MD-75, patients treated with cariprazine flexible doses of 2.0-4.5 mg/day in addition to ongoing antidepressant therapy met the primary endpoint and achieved improved MADRS total scores at week eight compared to placebo.
Based on the positive results of studies 3111-301-001 and RGH-MD-75, and the totality of data reported, AbbVie intends to submit a supplemental New Drug Application with the U.S. FDA for the expanded use of cariprazine for the adjunctive treatment of MDD.
