Patients on CAPLYTA sustained treatment over 6 months^1,2

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

Safety profile observed in the open-label trial was consistent with pivotal trials

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; EOLTP=end of open-label treatment period; MADRS=Montgomery-Åsberg Depression Rating Scale.

Study 503 - open-label safety trial in adults^2,5

Study design

Study 503 was an open-label safety extension study of patients with MDD continuing to receive CAPLYTA 42 mg adjunctive to an antidepressant (N=809).

Eligible patients completed lead-in Study 501 or Study 502
Open-label treatment period: Weekly visits through Week 4, then every 2 weeks through Week 26⁵
Primary outcome measure: Safety and tolerability^†
Secondary outcome measures: Maintenance of depressive symptoms, measured by MADRS total score change from Study 501 or 502 baseline to Week 26 of open-label treatment

^†The primary endpoint of the open-label trial was safety and tolerability of long-term CAPLYTA 42 mg adjunctive to ADT as assessed by AEs and vital signs (all visits) and clinical laboratory parameters and electrocardiogram findings (Day 1, Weeks 1, 8, 16, and 26). Suicidal ideation and behavior were assessed by the C-SSRS at every study visit and by AEs. EPS were assessed as AEs and by symptom rating scales, including the Abnormal Involuntary Movement Scale (AIMS), the Barnes Akathisia Rating Scale (BARS), and the Simpson-Angus Scale (SAS) (Day 1, Weeks 1, 4, 8, 12, 16, 20, 24, and 26).

AE=adverse event; EPS=extrapyramidal symptoms; C-SSRS=Columbia-Suicide Severity Rating Scale; MADRS=Montgomery-Åsberg Depression Rating Scale; MDD=major depressive disorder.

Full graph description

This graph depicts the change in depression symptom severity score in pooled 501 and 502 studies and the open-label extension Study 503. Also shown is patients receiving placebo + ADT in Study 501 and Study 502 that switched to CAPLYTA in Study 503. All patients in Study 503 received CAPLYTA + ADT over 6 months.²
