(MENAFN- GlobeNewsWire - Nasdaq) Ongoing Phase 1 trial of CTIM-76 (CLDN6 x CD3) demonstrates encouraging antitumor activity and safety Ongoing Phase 1 trial of CT-95 (MSLN x CD3) is approaching target dose levels
Cash and cash equivalents of $76.9 million as of September 30, 2025
PHILADELPHIA, Nov. 05, 2025 (GLOBE NEWSWIRE) -- Context Therapeutics Inc. (“Context” or the“Company”) (Nasdaq: CNTX), a clinical-stage biopharmaceutical company advancing T cell engaging bispecific antibodies for solid tumors, today provided a clinical update and reported its financial results for the third quarter ended September 30, 2025.
“We believe the early clinical data for CTIM-76 provides encouraging early signs of antitumor activity for Context's T cell engagers (“TCE”) in solid tumors where many other approaches have failed due to material safety issues or lack of efficacy,” said Martin Lehr, CEO of Context.“We look forward to continuing to advance Context's clinical trials and providing more detailed updates in 2026.”
Pipeline Updates
CTIM-76: CLDN6 x CD3 bispecific TCE in Phase 1 dose escalation for patients with ovarian, endometrial, or testicular cancer.
CLDN6 is enriched in a wide range of solid tumors, including ovarian, endometrial, lung, and testicular. CTIM-76 is a fully humanized bispecific TCE that is engineered to bind with high selectivity to CLDN6 and redirect the immune system's T cells to recognize and kill CLDN6-expressing cancer cells. More information about the CTIM-76 clinical trial (NCT06515613) can be found on .
Clinical update: Context has enrolled 12 patients as of the October 30, 2025 cutoff, and is currently enrolling Cohort 5 with a priming dose of 140 micrograms and a full dose of 560 micrograms. Preliminary signs of anti-tumor activity, including an ongoing RECIST response (Response Evaluation Criteria in Solid Tumors), have been observed beginning at Cohort 3 in the ongoing Phase 1 study. No Cytokine Release Syndrome (“CRS”) greater than Grade 1 has been observed in any cohort. No dose limiting toxicity (“DLT”) has been observed and a maximum tolerated dose (“MTD”) has not been reached. Guidance: Based on this safety profile, we are continuing dose escalation for CTIM-76 with the goal of further deepening RECIST responses, while maintaining a favorable safety profile. Context anticipates providing updated interim Phase 1a data and Phase 1b dose selection in the second quarter of 2026.
CT-95: MSLN x CD3 bispecific TCE in Phase 1 dose escalation for patients with pancreatic, non-small cell lung, ovarian, mesothelioma, and colorectal cancer.
Mesothelin (“MSLN”) is a membrane protein overexpressed in approximately 30% of cancers. CT-95 is a fully humanized bispecific TCE that is engineered to have moderate affinity but high avidity for membrane-bound MSLN, that is intended to minimize the impact of the shed MSLN that can serve as a decoy or sink for MSLN-targeting antibodies. More information about the CT-95 clinical trial (NCT06756035) can be found on .
Clinical update: 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 CRS greater than Grade 2 has been observed in any cohort. No DLT has been observed and an MTD has not been reached. Guidance: 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 in preclinical development for patients with bladder, non-small cell lung, colorectal, breast, and head and neck cancer.
Overexpression of Nectin-4 has been observed in many tumors, including bladder, lung, colorectal, and breast cancer, and is associated with tumor progression. CT-202 incorporates pH dependency to drive localized activity of CT-202 to the tumor microenvironment. CT-202 has shown in preclinical studies to exhibit little to no binding to CD3 or the target antigen in healthy tissue (normal alkaline microenvironment). However, in acid conditions that mirror the tumor microenvironment (high glycolysis), the binding of the antibodies to their target molecules is strong.
Guidance: Context expects to complete necessary regulatory filings to support the initiation of a first-in-human trial in the second quarter of 2026.
Third Quarter 2025 Financial Results
Cash and cash equivalents were $76.9 million at September 30, 2025, compared to $94.4 million at December 31, 2024. The Company expects its cash and cash equivalents will be sufficient to fund its operations into 2027. Research and development (“R&D”) expenses were $8.7 million for the third quarter of 2025, as compared to $16.8 million for the third quarter of 2024. The decrease in R&D expenses was primarily driven by lower CT-202 expense of $6.2 million and lower CT-95 expense of $2.8 million, partially offset by higher personnel-related costs of $0.7 million and higher CTIM-76 expense of $0.2 million. R&D expense for the third quarter of 2024 included in-process research and development charges of $14.75 million related to the acquisition of CT-95 and in-licensing of CT-202 in the third quarter of 2024. General and administrative expenses were $1.9 million for the third quarter of 2025 and the third quarter of 2024. Other income was approximately $0.9 million for the third quarter of 2025, as compared to other income of $1.2 million for the third quarter of 2024. This decrease was primarily due to lower interest income earned on lower average cash and cash equivalent balances. Context reported a net loss of $9.7 million for the third quarter of 2025, as compared to a net loss of $17.5 million for the third quarter of 2024.
