“We are encouraged by the Phase I dose escalation results as they continue to demonstrate the potential for BT8009 to be best-in-class for the treatment of urothelial cancer based on the observed anti-tumor activity and tolerability profile as well as the potential to treat other tumor types with significant unmet need,” said Kevin Lee, Ph.D., Chief Executive Officer. “Previously, we had reported a confirmed partial response in a non-small cell lung cancer patient and today we are pleased to announce a confirmed partial response in a breast cancer patient. Both of these patients are Nectin-4 positive. We are continuing to move forward with the dose expansion and Phase II portion of the clinical trial and look forward to providing an update by the end of 2023.”
