Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 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.


Secondary Outcome Measures :
  1. Change from baseline in Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: 1 week ]
    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.

  2. Change from baseline in Montgomery-Asberg Depression Rating Scale (MADRS) [ Time Frame: 4 weeks and 1 week ]
    Medium 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.

  3. Safety of BPL-003 given with psychological support as assessed by number and percentage of participants with adverse events [ Time Frame: 8 weeks ]
  4. Safety of BPL-003 given with psychological support as assessed by percentage of participants with clinically significant abnormal laboratory tests [ Time Frame: 8 weeks ]
  5. Safety of BPL-003 given with psychological support as assessed by percentage of participants with clinically significant abnormal vital sign measurements [ Time Frame: 8 weeks ]
  6. Safety of BPL-003 given with psychological support as assessed by percentage of participants with clinically significant ECG parameters compared [ Time Frame: 8 weeks ]
  7. Safety of BPL-003 given with psychological support as assessed by incidence of suicidal ideation or behavior [ Time Frame: 8 weeks ]
  8. Plasma levels of 5-MeO-DMT and its metabolites [ Time Frame: 1 day ]
