Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

An Open-Label and Randomized, Double-Blind, Placebo-Controlled, Multicenter Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Efficacy of SER-155 in Adults Undergoing Hematopoietic Stem Cell Transplantation to Reduce the Risk of Infection and Graft vs. Host Disease

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 1b randomized, double-blind, placebo-controlled, multiple dose, multicenter study designed to evaluate the safety, efficacy, and microbiome alterations associated with SER-155 dosing, after microbiome conditioning with oral vancomycin, in adult subjects aged ≥18 years who are undergoing Hematopoietic Stem Cell Transplantation (HSCT).
