Sanofi has signed a partnership deal worth potentially US $845 million with Voyager Therapeutics, a comparatively small biotech firm, becoming the latest in a series of major pharmaceutical firms to commit financially to gene therapy research.
According to a joint statement by the two companies, Genzyme, the Sanofi subsidiary involved in the deal, will work collaboratively with Voyager Therapeutics to develop and ultimately commercialise 'novel adeno-associated virus (AAV) gene therapies for Parkinson's disease, Friedreich’s ataxia, Huntington’s disease and other debilitating central nervous system disorders.
Dr Steven Paul, president and CEO of Voyager Therapeutics, says the alliance will ensure both companies 'are at the forefront of converting the promise of gene therapy into innovative therapies for CNS disorders that make a meaningful difference in patients' lives'.
According to the agreement, Voyager Therapeutics will oversee research and development of the specified gene therapy programmes, receiving an initial US $100 million upfront payment from Genzyme, including US $65 million in cash.
Should the programmes be successful and ultimately produce commercialised therapies, Voyager Therapeutics could receive up to US $745 million in 'development and sales milestones payments' and royalties.
Currently Voyager has two products - in Parkinson's disease and Friedreich's ataxia - in early clinical development, and others in preclinical trials.
Voyager Therapeutics will retain the rights to the Parkinson's and Friedreich’s ataxia programmes in the USA, and Genzyme will hold outside-US rights. The two companies plan to share any eventual US profits from the project in Huntington's disease. Genzyme will have licensing options for several other programmes after completion of proof-of-concept clinical trials.
According to industry analysts FierceBiotech, the company is 'also at work on new viral delivery vehicles that could mark a major improvement in the field'.
Genzyme's interest in gene therapy goes back over twenty years, enduring a fallow period when the technique appeared to many too problematic to ever bear commercial fruit. But last year Glybera, produced by the Dutch biotech UniQure, became the first gene therapy product to go on sale in Europe (see BioNews 782).
'We really carried the torch for years when some other companies left the space,' Mark Barrett, Genzyme's vice president of business development, told FierceBiotech.
