Rexahn Pharmaceuticals Announces Clinical Collaboration with Merck to Evaluate RX-5902 (Supinoxin) in combination with KEYTRUDA (pembrolizumab) for Triple Negative Breast Cancer

Rexahn Pharmaceuticals (NYSE:RNN), a clinical stage biopharmaceutical company developing innovative, targeted therapeutics for the treatment of cancer, today announced that it has entered into a clinical trial collaboration agreement with Merck (known as MSD outside the United States and Canada) to evaluate the combination of Rexahn’s RX-5902 and Merck’s anti-PD-1 therapy, KEYTRUDA (pembrolizumab) in a Phase 2 trial in patients with metastatic triple negative breast cancer (TNBC).

As quoted in the press release:

“Rexahn is excited to announce this collaboration with Merck, an established leader in the field of immuno-oncology,” said Peter D. Suzdak, Ph.D., chief executive officer of Rexahn. “RX-5902 has both antitumor and immune-modulatory effects and augments the efficacy of checkpoint inhibitors in animal models. Based on the mechanism of action of RX-5902 and our observations in preclinical studies, we are optimistic that the combination of RX-5902 with KEYTRUDA may provide meaningful clinical benefit in patients with metastatic triple negative breast cancer – a cancer that is notoriously difficult to treat”.

The study will evaluate the safety and efficacy of the combination of RX-5902 and KEYTRUDA in patients with metastatic TNBC who have progressed following at least one prior treatment.  Under the terms of the agreement, Rexahn will sponsor the RX-5902 and KEYTRUDA study.
