Seres Therapeutics (MCRB) said results from a phase 1b trial of SER-155 in people undergoing allogenic stem cell transplantation showed a "positive impact on biomarkers of systemic inflammation and immune homeostasis" compared with placebo.
The results back previous data showing that SER-155 "was associated with a significant reduction in bloodstream infections," the company said Thursday in a statement.
SER-155 is a live biotherapeutic designed to prevent infections in people undergoing allogenic stem cell transplantation to treat blood cancers, Seres said.
The company also said its cash runway was extended into Q1 2026.
