Outcome Measures
Primary Outcomes (2)
Core: Change From Baseline in Montgomery and Asberg Depression Rating Scale (MADRS) Total Score at Day 29 (12 mg vs 0.3 mg BPL-003)
The MADRS is a 10-item diagnostic questionnaire used to measure the severity of depressive episodes in participants with mood disorders. The MADRS was administered remotely throughout the trial by independent, centralized, qualified raters. The rater used the SIGMA to interview the participant, moving from broadly based questions about symptoms to more detailed questions that allowed the precise rating of symptom severity. The SIGMA provides structured probes to ensure standardization of administration and comprehensiveness of coverage of the 10 items of the scale. A higher MADRS score indicates more severe depression, with each item yielding a score of 0-6. Total overall scores therefore range from 0-60. The change from baseline in MADRS total score for 12 mg (high dose) vs 0.3 mg (low dose) BPL-003 at Day 29 was assessed.
4 weeks
OLE: Number of Participants With Treatment-emergent Adverse Events in the OLE
The safety of a second dose of BPL-003 given with psychological support to participants with TRD was assessed by the number and percentage of participants with treatment-emergent adverse events.

Limitations and Caveats
Core randomization was 1:1:1 and was modified to 3:1:3 in protocol version 3.0 (17 May 24) to enable recruitment to complete, reducing trial numbers from 225 to 203 participants. This reduced the numbers in the 8 mg arm but maintained the numbers in the 0.3 mg and 12 mg arms, preserving the power of the primary endpoint comparison. Overall randomization allocation ratio averaged to approximately 3:2:3. 5 SAEs reported, only 1 (suicidal ideation) was considered related to study drug.
