Context Therapeutics Inc. announced to extend its runway into First Quarter 2024. The company plans to defer noncritical R&D activities, reduce future overhead and infrastructure expenditures, and prioritize its onapristone extended release (ONA-XR) ELONA Phase 1b/2 clinical trial and Claudin 6 (CLDN6) program. The ELONA Phase 1b/2 clinical trial is evaluating ONA-XR, an oral progesterone receptor (PR) antagonist, in combination with Menarini's elacestrant in estrogen receptor positive (ER+), PR+, HER2- metastatic breast cancer (mBCa) patients who have previously been treated with a CDK4/6 inhibitor.

An IND amendment filed specifically for this trial was submitted to the U.S. Food and Drug Administration in September 2022. The Company remains on track to initiate the ELONA clinical trial in Fourth Quarter 2022 and to report Phase 1b data in Fourth Quarter 2023. Context retains worldwide rights for ONA-XR, other than the rights it out-licensed for Greater China.

Context anticipates the nomination of a CLDN6xCD3 bispecific monoclonal antibody (BsMAb) development candidate from the organization's research collaboration with Integral Molecular in Fourth Quarter 2022. An IND submission is planned in First Quarter 2024. Context retains worldwide rights to certain CLDN6 antibody patents in the field of bispecific antibodies.

In addition, Context will continue to provide access to ONA-XR through the Company's ongoing Investigator-Sponsored Trials (ISTs) and anticipates sharing preliminary data from its Phase 2 clinical trials in granulosa cell tumors and endometrial cancer in November 2022, and from its Phase 2 clinical trial in breast cancer in December 2022.
