This clinical trial is focused on studying a condition known as Treatment-Resistant Depression (TRD). TRD is a type of depression that does not improve after trying at least two different treatments. The study is testing a new treatment called BPL-003, which is a nasal powder containing the active substance mebufotenin benzoate. This treatment is being developed by Beckley Psytech Ltd and is administered through the nose.
The purpose of the study is to evaluate how effective and safe BPL-003 is for people with TRD. Participants will receive the treatment along with psychological support. The study will have two parts: an initial phase to determine how well the treatment works and a follow-up phase to assess its safety. During the study, participants will be monitored for any changes in their depression symptoms and any side effects they might experience.
Participants will be asked to attend several study visits where they will receive the treatment and undergo assessments. These assessments will help researchers understand how the treatment affects depression symptoms and overall health. The study aims to provide valuable information on whether BPL-003 can be a helpful option for people with TRD who have not found relief with other treatments.
