About

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)

Full 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.

Diagnosis:

For NSCLC patients Histologically or cytologically confirmed metastatic or locally advanced non-small cell lung cancer not amenable to curative treatment that have a confirmed progression on anti-PD-1/PDL1 therapy:

Subjects may have had a maximum of one prior line of therapy after failure of anti-PD-1/ Programmed death-ligand 1 (PDL1) therapy Received a platinum based chemotherapy for non-small cell lung cancer; or, Subjects with a documented activating mutation {e.g., against epidermal growth factor receptor (EGFR), against rearranged anaplastic lymphoma kinase (ALK), Proto-oncogene tyrosine-protein kinase (ROS)} must have received the appropriate targeted therapy.

For Melanoma patients Histologically confirmed unresectable or metastatic melanoma not amenable to curative treatment that have a confirmed progression on anti-PD-1/PD-L1 therapy: a. Subjects may have had a maximum of one prior line of therapy after failure of anti-PD-1/PDL1 therapy b. Subjects with a documented B-Raf (BRAF) mutation must have received the appropriate targeted therapy

For MSI-H/dMMR patients -Histologically confirmed MSI-H/dMMR metastatic solid tumors including the following indications: colorectal adenocarcinoma, gastric adenocarcinoma, esophageal adenocarcinoma, endometrial carcinoma, ovarian carcinoma, pancreatic ductal adenocarcinoma and urothelial carcinoma that had a confirmed progression on anti-PD-1/PD-L1-based therapy.

  • Biopsies Patients must agree to study biopsies at two time points: a. Pretreatment and on treatment gut biopsies. b. Pretreatment and on treatment tumor biopsies.
  • Measurable disease by RECIST v1.1.
  • Patient status: a. Eastern Cooperative Oncology Group (ECOG) status of 0-1 b. Liver function: Total bilirubin ≤ 2 Upper limit of normal (ULN), Alanine aminotransferase (ALT), and Aspartate aminotransferase (AST) ≤ 2.5 ULN (or < 5 in case of present liver metastasis) c. Neutrophils ≥ 1,000/mm3, platelets ≥ 100,000/mm3, Hb>8 g/dL d. Serum creatinine ≤ 1.5 ULN e. International normalized ratio (INR), prothrombin time (PT), and activated partial thromboplastin time (aPTT) ≤1.5x ULN
  • Pregnancy a. Negative urine or serum pregnancy test within 72 hours prior to receiving first dose of study procedure in women of childbearing potential. b. Use of an effective contraceptive method throughout the entire treatment period and up to 6 months after the completion of treatment in both males and females of child bearing potential.
