A Multicenter Phase 1b Randomized, Placebo-controlled, Blinded Study to Evaluate the Safety, Tolerability and Efficacy of Microbiome Study Intervention Administration in Combination With Anti-PD-1 Therapy in Adult Patients With Unresectable or Metastatic Melanoma

Parker Institute for Cancer Immunotherapy·interventional·Posted Jan 25, 2019·Updated Jun 6, 2024

In Brief

A Phase 1 clinical trial evaluating Placebo for antibiotic, Vancomycin pretreatment, and 3 other interventions for Metastatic Melanoma. Completed, enrolled 14 participants across 7 sites.

Detailed Summary

This study is designed to evaluate the safety and tolerability of treatment with oral microbiome study intervention (SER-401) or matching placebo in combination with anti-programmed cell death 1 (anti-PD-1) therapy (nivolumab) in participants with unresectable or metastatic melanoma. The study also intends to assess clinical outcomes, the impact of microbiome study intervention administration on the microbiome profile, and its association with clinical and immunological outcomes.
