Selexis and Tallac Therapeutics Collaborate to Advance Tallac’s Pipeline of Novel Immunotherapies in Oncology

Tallac Will Draw on Selexis’ Best-in-Class Cell Line Development Technologies Under New Commercial License and Service Agreements

Geneva, Switzerland, and Burlingame, CA — Selexis SA, a JSR Life Sciences company, and Tallac Therapeutics have signed both a commercial license agreement (CLA) and a service agreement (SA) to advance Tallac’s Toll-like Receptor Agonist Antibody Conjugate (TRAAC) platform, which harnesses the power of innate and adaptive immunity to treat cancer. Under the agreements, Tallac will employ Selexis’ proprietary SUREtechnology Platform™ to develop the research cell banks necessary to bring its immunotherapy candidates for the treatment of solid tumors to the clinic.

“We are proud to work with Tallac Therapeutics as the company develops new medicines for cancer,” said Yemi Onakunle, PhD, MBA, Selexis chief business officer. “Our work with Tallac will allow Selexis to play a role in the advancement of differentiated immunotherapies that are designed to overcome the resistance and lack of response seen in the majority of patients receiving currently available treatments.”
