Microbiota Therapy

FMT + Pembrolizumab for Melanoma

Phase 2
Waitlist Available
Led By Diwakar Davar, MD
Research Sponsored by Zarour, Hassane, MD
Eligibility Criteria Checklist
Specific guidelines that determine who can or cannot participate in a clinical trial
Must have
Patients with CNS progression (parenchymal but not leptomeningeal) are eligible if CNS metastases are treated and deemed stable (with a repeat CT/MRI imaging study) prior to the enrollment date. If radiation is used to treat CNS parenchymal disease, a 2 week washout period will apply (counted from Day 1 treatment). Stability must be confirmed with a repeat CT/MRI imaging study performed as part of the screening evaluation (at least 2 weeks after radiation). Patients with new CNS metastases identified during screening are ineligible.
Consent to receive FMT administered endoscopically (colonoscopically) and undergo necessary bowel preparation pre-procedure.
Must not have
Has a known history of active TB (Bacillus Tuberculosis).
Has a history of (non-infectious) pneumonitis that was life-threatening and/or required invasive support (CTCAE grade 4 or greater) or current pneumonitis.
Timeline
Screening 3 weeks
Treatment Varies
Follow Up up to 6.5 years

Summary

This trial is testing if FMT can help the body fight cancer.

Who is the study for?
Adults with advanced melanoma not responding to PD-1 immunotherapy can join this trial. They must be receiving pembrolizumab or nivolumab, have stable brain metastases if present, and agree to a fecal transplant via colonoscopy. Pregnant women, those with severe allergies or autoimmune diseases, and patients with certain serious health conditions are excluded.
What is being tested?
The study is testing whether adding a fecal microbiota transplant (FMT) to the existing PD-1 immunotherapy (pembrolizumab/nivolumab) helps improve the body's cancer-fighting abilities in melanoma patients who haven't responded well to treatment.
What are the potential side effects?
Potential side effects include reactions related to FMT such as infection risk from donor stool, allergic reactions, and possible long-term risks like obesity or autoimmune disorders. Colonoscopy risks include perforation and pneumonia.

Experimental Treatment
Group I: Fecal Microbiota Transplant (FMT) with PembrolizumabExperimental Treatment1 Intervention
The FMT along with an intestinal biopsy will be performed as outpatient by a gastroenterologist. The FMT is infused into the colon by performing a colonoscopy. FMT will be performed on Cycle 1 Day 1 and will take 15 to 30 minutes. Pembrolizumab, 200mg, through an IV over 30 minutes on Cycle 1 Day 1 (same day as the FMT), and then again on Day 1 of each 21-day cycle for an additional 3 cycles (Cycles 2 - 4).

Dr. Davar is very patient and caring, which is reassuring given my recent cancer diagnosis. He always takes the time to explain things to me so that I can understand them.
