U.S. FDA Approves VRAYLAR® (cariprazine) as an Adjunctive Treatment for Major Depressive Disorder
“A Phase 3 Study 3111-301-001 showed a clinically and statistically significant change from baseline to week six in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score for patients treated with cariprazine at 1.5 mg/day + ADT compared with placebo + ADT. A second registration-enabling study, RGH-MD-75, showed a clinically and statistically significant change from baseline to week eight in the MADRS total score for patients treated with cariprazine at 2-4.5 mg/day (mean dose 2.6 mg) + ADT compared with placebo + ADT.
Cariprazine was generally well tolerated in 6- and 8-week studies. Mean weight change was < 2lbs and ? 3% of patients had a weight increase of ? 7%.
The starting dosage of VRAYLAR is 1.5 mg once daily. Depending upon clinical response and tolerability, the dosage can be increased to 3 mg once daily on Day 15. In clinical trials, dosage titration at intervals of less than 14 days resulted in a higher incidence of adverse reactions. The maximum recommended dosage is 3 mg once daily.
Most common adverse reactions observed in the adjunctive MDD studies (? 5% and at least twice the rate of placebo) were:
Akathisia, nausea, and insomnia at the recommended doses in 6-week, fixed-dose trials
Akathisia, restlessness, fatigue, constipation, nausea, increased appetite, dizziness, insomnia, and extrapyramidal symptoms in one 8-week flexible-dose trial at a titration of less than 14 days”
