GHENT, Belgium, 20 July 2017 - Ablynx [Euronext Brussels: ABLX; OTC: ABYLY] today announced that it has entered into a research collaboration and global exclusive licensing agreement with Sanofi initially focused on developing and commercialising Nanobody®-based therapeutics for the treatment of various immune-mediated inflammatory diseases.

Under the terms of the agreement, Sanofi gains exclusive global rights to certain multi-specific Nanobodies against selected targets, with options for similar rights to additional targets, for a total of eight potential Nanobody product candidates.
