ReViral is a clinical-stage company focused on developing novel, anti-viral compounds that target respiratory syncytial virus (RSV). Founded in 2011, ReViral has an experienced R&D leadership team with a successful track record in antiviral drug discovery and development. The company has developed a novel antiviral programme targeting RSV fusion with highly potent, orally bioavailable inhibitors, strong drug-like characteristics and good pharmacokinetic properties offering versatility in the route of administration. The lead candidate RV521 completed a Phase IIa study in adult volunteers showing high potency and excellent safety. The company also has an RSV replication programme at an earlier stage of development and plans to expand its pipeline. In August 2018, ReViral completed a $55 million Series B funding round from a group of leading venture capital investors jointly led by New Leaf Venture Partners and Novo Ventures, part of Novo Holdings A/S, with additional new investment from Perceptive Advisors. Existing investors Andera Partners, OrbiMed and Brace Pharma Capital also participated in the fundraise.
