Verseon to present preclinical data on diabetic macular edema program and update on anticoagulation program at BIO 2017

Fremont, Calif.-Verseon, a technology-based pharmaceutical company employing a computer-driven platform to develop a diverse drug pipeline, today announces that it will present its most advanced drug programs at the 2017 BIO International Conference, one of the world's largest biotechnology events, held June 19-22, 2017 in San Diego.

Dr. David Kita, Vice President of R&D at Verseon, will present preclinical results on the Company's plasma kallikrein inhibitors for the treatment of diabetic macular edema (DME), a major cause of blindness worldwide that affects people with diabetes. The presentation will include pharmacokinetic data indicating that Verseon's drug candidates can be administered as eye drops. Moreover, some of Verseon's kallikrein inhibitors are suitable for oral dosing.

A second presentation will provide an update on Verseon's anticoagulation program. The Company's direct thrombin inhibitors have demonstrated efficacy comparable to existing anticoagulants in preclinical testing, but lower bleeding risk. In addition to results on Verseon's first development candidate, which shows significantly lower renal clearance than the current anticoagulants, Dr. Kita will also present new preclinical data on another promising lead candidate with a distinct chemotype.

"Our computer-driven approach to drug discovery has allowed us to develop multiple promising candidates across our pipeline," said Dr. Kita. "We are especially excited to share preclinical results on our DME candidates, which can potentially have a positive impact on millions of patients worldwide."

Details of the presentations are as follows:

About Verseon's diabetic macular edema program

Verseon has developed a new class of potent, selective compounds for the treatment of diabetic macular edema. The Company's plasma kallikrein inhibitors target a validated pathway addressing an underlying cause of the disease. In preclinical testing, Verseon's inhibitors show favorable biochemical properties permitting either oral or topical (eye drop) administration.

About Verseon's anticoagulation program

Verseon's potent, highly selective, oral direct thrombin inhibitors act through reversible covalent inhibition, a unique mode of action. Preclinical studies show that Verseon's inhibitors act as effective anticoagulants in multiple efficacy studies, but do not disrupt platelet function. This unique feature could explain their observed low bleeding risk. One of Verseon's lead candidates furthermore shows very low renal clearance, a highly desirable property for patients with impaired renal function.

About Verseon
