Fecal Microbiota(University of Pittsburgh)

In this is a randomized phase II study the addition of R-FMT to pembrolizumab /lenvatinib in PD-1 R/R melanoma will be evaluated over a 104-week period in patients with anti-PD-1 R/R disease. Patients with PD-1 refractory advanced melanoma are eligible to enroll, excluding patients with prior lenvatinib (or other TKI) exposure. Intestinal microbiome composition mediates response to anti-PD-1 by affecting systemic inflammatory tone.
