Migalastat rights returned by GSK to Amicus

GSK returns rights to migalastat HCl for Fabry disease, to Amicus which now has global rights.Under the terms of the revised agreement, there is no upfront payment from Amicus to GSK. For the next-generation Fabry ERT GSK is eligible to receive single-digit royalties on net sales in eight major markets outside the U.S. For migalastat HCl monotherapy, GSK is eligible to receive post-approval and sales-based milestones as well as tiered royalties in the mid-teens in eight major markets outside the U.S. The terms of the revised agreement replace the prior agreement in its entirety. Under the prior agreement entered into in July 2012, Amicus and GSK were co-developing migalastat HCl globally and GSK had rights to commercialise migalastat HCl outside the United States.
