Notes to Editors

About ReViral

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, sisunatovir, completed a Phase 2a trial in adult volunteers, showing high potency and was well tolerated. The company also has an RSV replication programme at an earlier stage of development and plans to expand its pipeline. In July 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 fundraising.

About Sisunatovir

Sisunatovir is an orally administered, small molecule fusion inhibitor being evaluated for the treatment of RSV. Sisunatovir blocks RSV replication by inhibiting RSV F-mediated fusion of RSV with the host cell. Preclinical tests showed sisunatovir to have an excellent toxicity profile with an attractive therapeutic index. In Phase 1 clinical studies, sisunatovir showed excellent exposure with no serious adverse events being reported. In 2018, sisunatovir generated positive results in a Phase 2a challenge trial in healthy adult volunteers, producing statistically significant reductions in viral load and clinical symptoms.

About Respiratory Syncytial Virus (RSV)

RSV is a pathogen that infects the human respiratory tract, potentially leading to bronchiolitis and pneumonia. While most (but not all) otherwise healthy people recover from the virus, there is an increased risk of severe disease and death in premature infants, individuals with certain pulmonary conditions, the elderly and those who are immune suppressed. In the United States, nearly all children become infected with RSV by age 2, with 75,000 to 125,000 of them hospitalized each year. Globally, RSV affects an estimated 64 million people and causes 160,000 deaths each year.
