For major depressive disorder (Adjunctive) in adultsOpen-label safety trial (Study 503) in adults

Patients on CAPLYTA sustained treatment over 6 months1,2

9 out of 10 patients chose to continue into the open-label safety extension, and 85% stayed on CAPLYTA during the 6-month, open-label safety trial

  • Safety profile observed in the open-label trial was consistent with pivotal trials
  • Rates of TEAEs decreased over time for most events*

*Most TEAEs (>98%) were mild or moderate in severity. 46.8% of patients with TEAEs had first onset within the first 4 weeks of open-label CAPLYTA administration.

MADRS total score over time2,3
This line graph shows changes in MADRS total scores over time from baseline through 26 weeks for patients receiving CAPLYTA 42 mg or placebo.

80% of patientsmet clinically defined response(reduction of MADRS total score ≥50%)

65% of patientsmet clinically defined remission(MADRS total score of ≤10)

Limitation: This open-label safety extension trial was designed primarily to assess long-term safety and tolerability. Efficacy outcomes are exploratory and should be interpreted with caution, as the study was not powered or controlled to assess treatment efficacy.

Remission defined as MADRS Total Score ≤10.

ADT=antidepressant therapy; EQLTP=end of open-label treatment period; MADRS=Montgomery-Åsberg Depression Rating Scale; TEAE=treatment emergent adverse event.
