What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change from baseline in Montgomery-Asberg Depression Rating Scale (MADRS)
Time Frame: 4 weeks
High compared to low dose of BPL-003. The MADRS is a 10-item diagnostic questionnaire used to measure the severity of depressive episodes in participants with mood disorders. A higher MADRS score indicates more severe depression, and each item yields a score of 0-6.
4 weeks
OLE Primary Safety Outcome Measure
Time Frame: 8 weeks
To determine the safety of a second dose of BPL-003 given with psychological support to participants with TRD as assessed by treatment-emergent adverse events.
8 weeks

Secondary Outcome Measures

Measure Description
Time Frame
Safety of BPL-003 given with psychological support as assessed by number and percentage of participants with adverse events
Time Frame: 8 weeks
8 weeks
Safety of BPL-003 given with psychological support as assessed by percentage of participants with clinically significant abnormal laboratory tests
