PHILADELPHIA, Nov. 07, 2025 (GLOBE NEWSWIRE) -- Context Therapeutics Inc. ("Context" or the "Company") (NASDAQ:CNTX), a clinical-stage biopharmaceutical company advancing T cell engaging ("TCE") bispecific antibodies for solid tumors, today shared two posters discussing the Company's CT-95 and CT-202 programs at the Society for Immunotherapy of Cancer's (SITC) 40th Annual Meeting, being held November 7–9, 2025 in National Harbor, MD.

CT-95 and CT-202 Highlights and Near-Term Milestones

CT-95: Mesothelin x CD3 bispecific TCE

CT-95 is avidity enhanced and affinity tuned to localize therapeutic activity to the tumor microenvironment.
In an ongoing Phase 1 trial, Context has enrolled 6 patients as of the October 30, 2025 cutoff, and is currently enrolling Cohort 3 with a priming dose of 0.18 µg/kg and a full dose of 0.6 µg/kg.
Based on preclinical data, CT-95 is projected to achieve target dose exposure starting at Cohort 4.
No cytokine release syndrome (CRS) greater than Grade 2 has been observed in any cohort. No dose limiting toxicity (DLT) has been observed and a maximum tolerated dose (MTD) has not been reached.
Based on this safety profile, we are continuing dose escalation for CT-95 toward target dose levels. Context anticipates providing initial Phase 1a data in the middle of 2026.

CT-202: Nectin-4 x CD3 bispecific TCE

Preclinical data supports best-in-class potential of CT-202.
Demonstrates potent preclinical activity with a favorable pharmacokinetic and safety profile, supporting its expected transition into clinical studies.
Expect to complete necessary regulatory filings to support the initiation of a first-in-human trial in the second quarter of 2026.

A copy of the presentation materials will be made available on the "Publications and Posters" section of the Company's website at https://www.contexttherapeutics.com/publications.

About CT-95

CT-95 is a mesothelin ("MSLN") x CD3 TCE bispecific antibody that is intended to redirect T-cell-mediated lysis toward malignant cells expressing MSLN. MSLN is a membrane protein overexpressed in approximately 30% of cancers. One challenge in developing MSLN-targeted therapies has been the presence of MSLN fragments, also referred to as shed MSLN, found in both blood and the tumor microenvironment that can serve as a decoy or sink for MSLN-targeting antibodies. CT-95 is a fully humanized bispecific T cell engager that has a moderate affinity but high avidity for membrane-bound MSLN, that is intended to minimize the impact of the shed MSLN. The clinical trial is being conducted at clinical sites in the US. More information about the CT-95 clinical trial (NCT06756035) can be found on https://clinicaltrials.gov.

About CT-202

CT-202 is a Nectin-4 x CD3 TCE bispecific antibody that targets Nectin-4, a cell surface protein that is highly and frequently overexpressed in a variety of solid tumors, including bladder, colorectal, lung and breast. Nectin-4 is a clinically validated target for cancer therapy using a traditional antibody-drug conjugate ("ADC"), but it is also associated with certain adverse events, including neuropathy and rash. CT-202 is a pH-dependent TCE that is designed to be preferentially active within the tumor microenvironment.
