Clinical Trial Summary

A Phase Ib trial to evaluate the safety and efficacy of Fecal Microbial Transplantation (FMT) in combination with Nivolumab in subjects with metastatic or inoperable melanoma, microsatellite instability-high (MSI-H) or mismatch-repair deficient (dMMR) cancer, or Non-Small Cell Lung Cancer (NSCLC)

Description:

This study is a Phase I single-center adaptive design study to evaluate the safety and efficacy of FMT in combination with Nivolumab for adult subjects with treatment-refractory or inoperable melanoma, MSH-H, dMMr or NSCLC.

FMT will be conducted with fecal capsules, originating from patients that have achieved a durable complete response with immune checkpoint inhibitors. The study will evaluate the safety and efficacy of the combination of FMT with Nivolumab, a human immunoglobulin G4 (IgG4) monoclonal antibody that blocks PD-1 (anti PD-1) treatment and explore different biomarkers.
