Acquisition expands Pfizer’s anti-infective pipeline and reinforces commitment to developing both medicines and vaccines to help combat respiratory syncytial virus (RSV)
NEW YORK--(BUSINESS WIRE)--Jun. 9, 2022--
Pfizer Inc. (NYSE: PFE) today announced the successful completion of its acquisition of ReViral, a privately held, clinical-stage biopharmaceutical company focused on discovering, developing, and commercializing novel antiviral therapeutics that target respiratory syncytial virus (RSV).
ReViral brings to Pfizer a portfolio of promising therapeutic candidates, including sisunatovir, an orally administered inhibitor designed to block fusion of the RSV virus to the host cell. Sisunatovir has been granted Fast Track designation by the U.S. Food and Drug Administration (FDA). It significantly reduced viral load in a phase 2 RSV human challenge study in healthy adults and is currently in phase 2 clinical development in infants. The development program for sisunatovir is expected to continue in both adult and pediatric populations. A second program is focused on the inhibition of RSV replication targeting the viral N protein. The lead candidate in this program is currently in phase 1 clinical development.
“We are excited to bring ReViral’s promising investigational treatments for RSV into our anti-infective pipeline at Pfizer. This acquisition further demonstrates our commitment to advancing pioneering science – both through our in-house expertise and our work with leading, innovative companies – with the goal of delivering new breakthroughs to patients suffering from serious infectious diseases,” said Mikael Dolsten, M.D., Ph.D., Chief Scientific Officer and President, Worldwide Research, Development and Medical of Pfizer. “We believe these therapeutic candidates – and the scientific expertise that has advanced their development – will complement our ongoing work to help combat RSV infections, and we look forward to welcoming our new colleagues to further support these endeavors.”
RSV is a respiratory pathogen, which can lead to severe and life-threatening lower respiratory tract infections (LRTIs) in high-risk populations, including young children, immunocompromised individuals, and older adults. It is estimated to cause infections in approximately 64 million people, resulting in about 160,000 deaths, globally each year. Currently, treatment options for RSV are limited, with care management focused primarily on supportive measures for people with the illness.
Additional Transaction Details
Under the terms of the agreement, Pfizer acquired ReViral for a total consideration of up to $525 million, including upfront and development milestones. If successful, Pfizer believes annual revenue for these programs has the potential to reach or exceed $1.5 billion.
