Summary

This trial is testing whether a fecal transplant can help people with depression who haven't responded to other treatments.

Who is the study for?
Adults aged 18-65 with Major Depressive Disorder (MDD) who haven't improved after trying at least two antidepressants can join this trial. They must have a specific depression score (≥19 on the MADRS scale), be on stable antidepressant treatment for 8 weeks, and not use certain medications or have chronic gastrointestinal diseases, immune suppression, or severe psychiatric conditions.
What is being tested?
The trial is testing if swallowing FMT oral capsules is safe and effective for treating Treatment Resistant Depression compared to placebo capsules. Participants are randomly given either the real treatment or a placebo to see if there's an improvement in their depression symptoms.
What are the potential side effects?
While the side effects of FMT oral capsules aren't fully known yet, potential risks may include digestive discomfort, allergic reactions to capsule components, and changes in bowel habits.

Trial Design

2Treatment groups
Active Control
Placebo Group
Group I: FMT capsulesActive Control1 Intervention
Each dose of FMT capsules consists of 20 capsules. The 20 over encapsulated capsules are derived from 100 grams of stool and each containing 0.67 ml of pelleted intestinal microbes. PArticipants will recieve a loading dose of 60 capsules over 3 consecutive days followed by a booster dose of 20 caspules 1 month after and a second similar booster dose a month after that
Group II: Placebo oral CapsulesPlacebo Group1 Intervention
Placebo casules are inactive capsules that look and weigh the same as the Active FMT caspules. Participants will follow the same schedule as the Active arm.
