This study is a phase 2/3 open-label controlled trial (CT) in which adults with Major Depressive Disorder (MDD) and adults who have MDD plus comorbid Inflammatory Bowel Syndrome (IBS) will be assigned to either receive oral Fecal Microbiota Transplantation (FMT) or to continue with the treatment they are currently receiving in a Treatment As Usual (TAU) arm. An IBS alone group receiving TAU will be recruited as a clinical control group.
The primary goals of this study are to determine effectiveness, safety and tolerability of oral FMT in adults with MDD and in MDD who have comorbid IBS. Additional goals are to characterize patterns and progressions of cognitive and neural correlates associated with MDD and with MDD + IBS and to determine if they improve with FMT. It is known that both, individuals with MDD and those with MDD and IBS show cognitive alterations as well as changes in neural structures, but this study is designed to see if those are changed with treatment response to FMT. Additionally, trial feasibility will be monitored via recruitment rate, study visits adherence and participant retention to inform future trial scalability."

| Participants with a confirmed diagnosis of MDD receiving TAU | No Intervention | Eligible and consenting patients will be assigned 1:1 to receive either FMT from a healthy donor or continuing on their usual medication for MDD, i.e., treatment as usual (TAU).

| Fecal Microbiota Transplantation | Biological | FMT is a technique in which intestinal microbiota are transferred from a healthy screened donor to a patient, with the goal being to introduce or restore a stable microbial community in the gut. |
| Measure | Description | Time Frame |
|---|---|---|
| The Montgomery-Ã…sberg Depression Rating Scale (MADRS) | a 10-item questionnaire which psychiatrists use to measure the severity of depressive episodes in patients with mood disorders. This will be used to evaluate the effectiveness of adjunct oral FMT as compared to TAU with currently accepted approved therapy for MDD. The MADRS overall score ranges from 0 to 60. Each item yields a score of 0 to 6 and Higher MADRS score indicates more severe depression | Baseline to week 13 |
| IBS Symptom Severity Scale (IBS-SSS) | The IBS-SSS is a 5-item questionnaire that is used to assess the severity and frequency of abdominal pain, severity of abdominal distention, dissatisfaction with bowel habits, and interference with quality of life over the past 10 days. Scores on the IBS-SSS can range from 0 to 500 with higher scores indicating more severe symptoms. Subjects can be categorized as having mild (75-175), moderate (175-300), or severe (>300) IBS. | Baseline to week 13 |
| Measure | Description | Time Frame |
|---|---|---|
| Toronto Side Effect Scale (TSES) | The TSES is a 32-item instrument that is designed to establish incidence, frequency, and severity of CNS, GI, and sexual side effects. For each side effect, frequency and severity are measured on a 5-point scale. intensity is measured by multiplying frequency and severity. | Baseline to Week 13 |
| Measure | Description | Time Frame |
|---|---|---|
| structural and functional neuroimaging | fMRI to examine brain imaging changes in response to FMT | Baseline to week 13 |
| Number of participants recruited, and completed the study visits | trial feasibility will be monitored via recruitment rate, study visits adherence and participant retention to inform future trial scalability |
