Summary

This study tests a new nasal spray called BPL-003, combined with psychological support, in 64 people with treatment-resistant depression (depression that hasn't improved with at least two prior medications). The goal is to see if it's safe and how it affects mood. Participants will receive one or two doses and be monitored for side effects and changes in depression symptoms.

What this could lead to

If successful, this could point toward a new treatment option for people with depression that hasn't responded to standard medications.

What could go wrong

This is an early Phase 2a study with only 64 participants, open-label (no placebo), so results may not be definitive. Risks include side effects and potential for suicidal thoughts.
