Prevail Therapeutics (Prevail), a biotechnology company developing gene therapies for patients with Parkinson's disease and other neurodegenerative diseases, today announced a $75 million Series A financing.

Investors in the round included OrbiMed, Pontifax Fund, RA Capital Management, EcoR1 Capital, Omega Funds, BVF Partners L.P., Boxer Capital, LLC, Adage Capital Management L.P., and Alexandria Venture Investments. OrbiMed and the Silverstein Foundation for Parkinson's with GBA incubated and provided seed funding to Prevail.

Prevail is pioneering the development of gene therapies with a goal of addressing the underlying disease process in Parkinson's disease and other neurodegenerative disorders. The proceeds of the Series A financing will be used to advance Prevail's pipeline of AAV-based (adeno-associated virus) therapeutics targeting lysosomal dysfunction to treat patients with genetically-defined neurodegenerative diseases. Prevail's lead program, PR001, will be developed for a genetic subset of Parkinson's disease and other mechanistically-related disorders.

"This financing supports our plan to develop a pipeline of gene therapies with the potential to dramatically improve the lives of patients with a range of genetically-defined neurodegenerative diseases," commented Asa Abeliovich, M.D., Ph.D., Founder and Chief Executive Officer of Prevail. "Our lead program will target patients with Parkinson's disease, and we plan to address additional disease areas where lysosomal dysfunction is an underlying cause. We're pleased to have attracted the support of this group of leading life science investors as well as the Silverstein Foundation for Parkinson's with GBA."

Commented Jonathan T. Silverstein, General Partner and Co-head of Global Private Equity at OrbiMed and founder of the Silverstein Foundation, "Prevail's mission to develop gene therapies that address the underlying genetic causes of neurodegenerative disease is aligned with our commitment to identify treatments that can halt the progression of Parkinson's and other diseases. The Company has assembled an excellent team to accomplish this mission, including executive management, scientific advisors, and board members, and I look forward to working with them to make a difference for patients."

Prevail has an exclusive worldwide license agreement with REGENXBIO Inc. to develop and commercialize gene therapy products using REGENXBIO's NAV AAV9 vector for the treatment of Parkinson's disease and other related neurodegenerative diseases.

ABOUT PARKINSON'S DISEASE

Parkinson's disease is a progressive neurodegenerative disorder that affects more than 10 million people worldwide. Gene mapping in recent years has led to the identification of new genes and risk factors for Parkinson's and related disorders including the glucocerebrosidase (GBA1) gene mutation. First observed in 2004, GBA1 is the most common of currently known Parkinson's mutations, and it is estimated that up to 10 percent of people with Parkinson's in the United States carry this mutation. Recent discoveries around the link between the GBA1 gene, glucocerebrosidase (GCase) protein production, and accumulation of alpha-synuclein in the brain may have implications for the broader Parkinson's population, as well as in other neurodegenerative diseases.
