Promising Results for SER-155
The highlight of the earnings call was the promising results from the Phase Ib study of SER-155.

With a number needed to treat of just three to prevent one infection, the results are encouraging. Additionally, the safety profile of SER-155 was confirmed to be similar to that of a placebo, underscoring its potential as a safe therapeutic option.
Phase II Study Plans for SER-155
Building on the success of the Phase Ib study, Seres Therapeutics is planning a robust Phase II study for SER-155. This upcoming study will be a well-powered, placebo-controlled trial targeting approximately 248 participants. The primary endpoint will focus on preventing bloodstream infections, with interim data expected within 12 months of the study’s initiation.
Robust Financial Management
Seres Therapeutics reported a decrease in net loss from continuing operations, which fell to $19.9 million in Q2 2025 from $26.2 million in Q2 2024. The company also managed to reduce research and development expenses by $2.9 million compared to the previous year, reflecting effective financial management strategies.
Partnership and Funding Initiatives
The company is actively engaged in discussions with multiple parties regarding potential partnerships, out-licensing deals, and mergers. A notable financial development was the receipt of a $25 million installment payment from Nestlé, which bolsters Seres’ funding efforts.
Positive Developments in Europe
Feedback from European Key Opinion Leaders (KOLs) has been positive regarding the potential of SER-155. Plans are underway to include European countries in the upcoming Phase II study, indicating a strategic expansion into the European market.
Challenging Biotech Environment
Despite the positive developments, Seres Therapeutics acknowledged the continued challenges within the biotech sector, particularly in securing capital to advance its development programs. This acknowledgment reflects the broader industry trends impacting biotech companies.
Cash Runway Concerns
Seres Therapeutics reported having $45.4 million in cash and cash equivalents, which is projected to fund operations only into the first quarter of 2026. The company is evaluating potential cost reduction actions to extend its cash runway, highlighting the need for strategic financial planning.
Forward-Looking Guidance
Looking ahead, Seres Therapeutics provided guidance on several key initiatives. The company emphasized the progress of SER-155, with a planned Phase II study aiming to enroll approximately 248 participants. Financially, Seres is actively pursuing partnerships and other strategies to extend its cash runway, currently projected into early 2026. Strategic transactions, including potential mergers, are also being considered to leverage their expertise in live biotherapeutics.
In summary, Seres Therapeutics Inc.’s earnings call presented a balanced view of optimism and caution. While the company has made significant strides in clinical developments and financial management, challenges in funding and the broader biotech environment remain. Investors and stakeholders will be keenly watching the upcoming Phase II study of SER-155 and the company’s strategic financial maneuvers.
