Written by Customer Service on . Posted in Earnings Releases And Operating Results.

BOSTON, Nov. 14, 2025 (GLOBE NEWSWIRE) — Sensei Biotherapeutics, Inc. (Nasdaq: SNSE), a clinical stage biotechnology company focused on the discovery and development of next-generation therapeutics for cancer patients, today reported financial results for the third quarter 2025.

On October 30, 2025, the Company announced that its Board of Directors determined, after extensive consideration of the Company’s development pipeline and current market conditions, to discontinue development of solnerstotug and initiate a comprehensive review of strategic alternatives aimed at maximizing shareholder value. The Company is exploring a range of strategic alternatives that may include, among other options, a sale of assets, licensing arrangements, collaborations, a sale of the Company, a business combination, a merger, or an orderly wind-down of operations.

In connection with this strategic review, the Company has implemented a workforce reduction to preserve cash, reducing its workforce by approximately 65 percent. The Company is retaining a small team of employees to assist in exploring strategic alternatives, maintaining compliance with regulatory and financial reporting requirements, and managing the orderly cessation of development activities.
