CT-95 is a potentially first-in-class mesothelin x CD3 bispecific antibody

Acquisition expands Context pipeline with second clinical-stage T cell engager for solid tumors

PHILADELPHIA, July 10, 2024 (GLOBE NEWSWIRE) -- Context Therapeutics Inc. ("Context" or the "Company") (NASDAQ:CNTX), a biopharmaceutical company advancing medicines for solid tumors, today announced that it has entered into an asset purchase agreement under which the Company has acquired CT-95, formerly owned by Link Immunotherapeutics, Inc. ("Link"), a mesothelin ("MSLN") x CD3 T cell engaging ("TCE") bispecific antibody with first-in-class potential that has received Investigational New Drug ("IND") clearance from the U.S. Food and Drug Administration. CT-95 is on track for Phase 1 initiation in the first quarter of 2025.

"We are thrilled to add CT-95, formerly known as LNK101, to our pipeline. The successful acquisition of this MSLN x CD3 bispecific antibody is consistent with our focus on building a pipeline of TCE assets to treat solid tumors," said Martin Lehr, CEO of Context. "Context identified MSLN as a target of interest due to its high prevalence in underserved solid cancers, including ovarian, lung, and pancreatic. Based on the compelling preclinical data generated to date, we believe that CT-95 has the potential to be both a first-in-class and best-in-class MSLN-targeting TCE."

Mr. Lehr continued, "CT-95 is an IND-cleared asset that we plan to rapidly progress into clinical trials. We intend to fund the acquisition of CT-95 and its advancement through the dose escalation portion of a Phase 1 clinical trial with Context's existing cash."

About CT-95

MSLN is a membrane protein overexpressed by many cancers with limited expression in normal tissues. One challenge in developing MSLN-targeted therapies has been the presence of a shed MSLN sink found in both blood and the tumor microenvironment. CT-95 is a fully humanized bispecific TCE that employs an IgG-scFv architecture with an effector-silenced IgG1 backbone and has a relatively low affinity but high avidity for membrane-bound MSLN, minimizing the impact of the shed sink. CT-95 is being developed as a therapy for advanced cancers associated with MSLN expression.
