About this study

Official title: A Quadruple Masked, Dose-Finding Study to Evaluate the Efficacy and Safety of Intranasal BPL-003, With Open Label Extension, in Patients With Treatment-Resistant Depression

This is a Phase 2 study randomized, quadruple-masked, multi-center trial with an open-label extension (OLE), designed to investigate the efficacy and safety of BPL-003 in patients with treatment resistant depression (TRD).

Read the detailed description

During the main part of the trial, approximately 200 eligible participants will receive a either a low (sub-therapeutic), medium, or high single dose of BPL-003, given intranasally, with 8 weeks of follow-up assessments.

Following this, participants may receive a second high dose of BPL-003 during the OLE, given intranasally as either a single spray or two sprays 10 minutes apart, with another 8 weeks of follow-up assessments.

Psychological support will be given before, during, and after each dose.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: 4 weeks

  2. 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.

    Measured: 8 weeks

Secondary outcomes (4)
  1. Core: Change From Baseline in MADRS Total Score at Day 8 (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 change from baseline in MADRS total score for 12 mg (high dose) vs 0.3 mg (low dose) BPL-003 at Day 8 was assessed.

    Measured: 1 week

  2. Core: Change From Baseline in MADRS Total Score at Day 29 (8 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.

  3. Core: Change From Baseline in MADRS Total Score at Day 8 (8 mg vs 0.3 mg BPL-003)

    Measured: 1 week

  4. Core: Number of Participants With Treatment-emergent Adverse Events in the Core Trial Period

    The safety 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. Any clinically significant findings during the trial have been included as adverse events.

    Measured: 8 weeks

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 10 Sep 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?

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) (time frame: 4 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05870540, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
