Clinical Collaboration with Bayer
Olema Pharmaceuticals has entered into a clinical trial collaboration and supply agreement with Bayer Consumer Care AG to evaluate OP-3136 in combination with NUBEQA® (darolutamide) for metastatic castration-resistant prostate cancer (mCRPC).
-
Phase 1b/2 Study Initiation
The Phase 1b/2 study, designed to assess safety, tolerability, and preliminary anti-tumor activity in approximately 36 patients, is expected to initiate in the second half of 2026.
-
Favorable Partnership Terms
Bayer will supply darolutamide for the study, while Olema will lead the conduct of the study and maintain full global commercial and marketing rights to OP-3136. Clinical data and inventions related to the combined use will be jointly owned.
-
Pipeline Validation and Expansion
This agreement marks the first clinical collaboration for OP-3136, expanding its potential therapeutic indications beyond breast cancer into prostate cancer and validating its potential following recent positive Phase 1 data.
Analysis
This collaboration with Bayer for a Phase 1b/2 study of OP-3136 in metastatic prostate cancer is a significant validation of Olema's pipeline, especially following recent positive Phase 1 data for OP-3136 and the company's prior 'going concern' warning. It expands the potential market for OP-3136 and leverages Bayer's expertise and drug supply, while Olema retains full commercial rights. This partnership could help address investor concerns about the company's financial runway.
