Catalyst Biosciences, Inc., the leading company in the discovery and development of engineered proteases, today announced that Pfizer Inc. has initiated a Phase 1 clinical trial for PF-05280602, an investigational proprietary, engineered variant of recombinant human Factor VIIa developed by Catalyst Biosciences. PF-05280602 has been engineered to provide improved acute and prophylactic treatment for hemophilia A & B patients with inhibitors. The IND filing and initiation of the Phase 1 clinical trial triggered additional milestone payments of $7.0 million payable to Catalyst by Pfizer under the terms of their research and license agreement.
"We are very excited to see the lead candidate from Catalyst's hemostasis franchise advance into human clinical trials," said Nassim Usman, Ph.D., Catalyst's CEO. "In parallel, Catalyst is independently achieving significant progress in engineering next-generation recombinant human Factor IX and Xa variants with highly differentiated advantages for the treatment of acute and prophylactic bleeding disorders, including hemophilia and non-hemophilia indications. We are diligently executing on our goal of expanding Catalyst's high-value pipeline of novel engineered proteases."
