SAN DIEGO, CA, USA and FREIBURG, Germany I August 13, 2020 I Prometheus Biosciences, Inc., (“Prometheus”) a biopharmaceutical company committed to the discovery, development, and commercialization of a broad portfolio of novel precision therapeutics and companion diagnostics for patients living with significant unmet medical needs in inflammatory bowel disease, and Dr. Falk Pharma GmbH (“Falk”) announced today that they have entered into an agreement to develop and commercialize PR600, Prometheus’ cell signaling program that targets a receptor of the tumor-necrosis factor superfamily for the treatment of IBD.  PR600 was discovered through Prometheus’ proprietary precision medicines platform, Prometheus 360™, and is currently in preclinical development. 

Under the terms of the agreement, Prometheus and Falk will share responsibility for the global development of PR600, with Falk contributing one-quarter of the costs associated with developing PR600 and its companion diagnostic from preclinical stage through commercial launch. Falk will exclusively commercialize PR600 in Europe, Australia and New Zealand, and Prometheus is eligible to receive royalty payments on those sales; Prometheus retains all commercialization rights in the U.S. and rest of world.  

“Dr. Falk Pharma GmbH is a recognized global leader in developing and commercializing GI drugs and we are thrilled to partner with them to advance PR600 toward the clinic and eventually to patients,” said Mark McKenna, President and Chief Executive Officer, Prometheus Biosciences. “This global partnership represents further validation of our Prometheus 360™ precision platform and enables Prometheus to potentially bring benefit to IBD patients across the globe, while building significant value for our stakeholders. We have great respect for Falk and their development and commercialization expertise and we look forward to working closely with them to execute on our shared vision for PR600.”

“We believe that one of the best uses of our resources is to invest in cutting-edge science and companies that will significantly change the IBD medicines treatment landscape. This global collaboration combines Prometheus’ emerging IBD medicines platform technology with Falk’s extensive development and commercialization expertise,” said Roland Greinwald, Managing Director Medicine & Pharmaceutics, Dr. Falk Pharma GmbH.  “We look forward to working with Prometheus to advance PR600, a novel precision antibody, for the treatment of patients suffering with IBD.”
