Galapagos initiates Phase 1 study with novel CF potentiator GLPG3067 - Seite 2

About the Galapagos-AbbVie collaboration in cystic fibrosis
In September 2013 Galapagos and AbbVie entered into a global collaboration agreement focused on the discovery and worldwide development and commercialization of potentiator and corrector molecules for the treatment of CF. Under the terms of the agreement, AbbVie made an upfront payment of $45 million to Galapagos. Upon successful completion by Galapagos of clinical development through to completion of Phase 2, AbbVie will be responsible for Phase 3, with financial contribution by Galapagos. Galapagos has earned $57 million in milestone payments to date and is still eligible to receive up to approximately $560 million in total payments for developmental and regulatory milestones, sales milestones upon the achievement of minimum annual net sales thresholds and additional tiered royalty payments on net sales, ranging from mid-teens to 20%. Galapagos has commercial rights to China and South Korea, and has an option to co-promote in Belgium, Netherlands, and Luxembourg.
