Bayer Evaluating Next Steps for Repinotan Compound

Compound for new type of stroke treatment did not meet the anticipated clinical benefit

- Bayer HealthCare will be ending its current development program for Repinotan, a substance for the treatment of acute ischemic stroke patients. A recently completed Phase IIb clinical trial with the Repinotan compound did not fulfil expectations. Repinotan, which belongs to the neuroprotectant class of drugs, did not meet the primary endpoints of the study and the anticipated clinical benefit could not be demonstrated in this very challenging clinical research area.

Bayer HealthCare continues to develop innovative treatments that address unmet patient needs. While ending the development with Repinotan in stroke, Bayer is still considering other options for the future of this compound.
