AI Summary
Q3 2025

SER-155 Progress: Key priority remains advancing SER-155 into Phase II for preventing bloodstream infections in allo-HSCT patients, with positive interim data expected within 12 months of study start, pending funding.

FDA Alignment: Seres received constructive FDA feedback and has alignment on critical Phase II study parameters, clearing protocol hurdles to begin the trial once funding is secured.

Financial Update: Reported $8.2 million net income from continuing operations in Q3, a turnaround from a $51 million loss last year, primarily due to a $25 million payment from the VOWST sale.

Cost Reductions: Implemented targeted cost cuts, including a 25% workforce reduction, to extend cash runway through Q2 2026.

New Funding: Received up to $3.6 million in non-dilutive CARB-X funding to develop an oral liquid formulation of SER-155 for broader patient access.

Clinical Expansion: Ongoing investigator-sponsored trial at MSK is evaluating SER-155 in immune-related enterocolitis, with initial safety and symptom data anticipated in early 2026.

Partnership Focus: Securing capital or partnerships to advance SER-155 is top priority, though no specifics were disclosed about ongoing discussions.
