REDWOOD CITY, Calif., May 27, 2025 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (“Coherus,” NASDAQ: CHRS), today announced a clinical collaboration with STORM Therapeutics, Ltd. (“STORM”) to evaluate STC-15, a METTL3 inhibitor, in combination with LOQTORZI (toripalimab-tpzi), a next-generation PD-1 inhibitor, in a Phase 1b/2 study for the treatment of non-small cell lung cancer (NSCLC), head and neck squamous cell carcinoma (HNSCC), melanoma and endometrial cancer.

“We are excited to partner with STORM on the development of the LOQTORZI/STC-15 combination, with patient dosing underway in the Phase 1b/2 study,” said Theresa LaVallee, Ph.D., Chief Scientific and Development Officer of Coherus. “This collaboration is another example of our strategy for expanding potential LOQTORZI indications beyond NPC through cost-efficient drug supply agreements and evaluating LOQTORZI with novel mechanisms in prioritized tumor types such as NSCLC, HNSCC, and others.”

The phase 1b study will evaluate STC-15, a METTL3 inhibitor, in combination with LOQTORZI to determine the safety and efficacy of the combination. The phase 2 portion of the study will evaluate expansion cohorts in NSCLC, HNSCC, endometrial cancer and melanoma, in up to 188 patients in the United States. (NCT06975293)

Under the terms of the clinical trial collaboration and supply agreement, Coherus will provide LOQTORZI to STORM, which will be the sponsor of the Phase 1b/2 clinical combination trial. STORM and Coherus each retain all commercial rights to their respective compounds, including as monotherapies or as combination therapies.
