Ipsen, a global specialty-driven pharmaceutical company, and Inspiration Biopharmaceuticals, a biopharmaceutical company focused on hemophilia, have entered into an Asset Purchase Agreement (APA) whereby healthcare company Baxter International will acquire worldwide rights to OBI-1, a recombinant porcine factor VIII (rpFVIII) in development for congenital hemophilia A with inhibitors and acquired hemophilia A, and Ipsen's industrial facility in Milford, Mass.
Baxter has agreed to pay $50 million upfront, up to $135 million in potential additional development and commercial milestones as well as tiered net sales payments ranging from 12.5% to 17.5% of OBI-1 annual net sales.
The sale is a result of joint marketing and sale process pursued by Ipsen and Inspiration shortly after Inspiration filed for protection under Chapter 11 in October of last year. Ipsen has been providing Inspiration with Debtor-in-Possession financing (DIP) for an amount of up to $18.3 million in order to permit the sale process to proceed.
In addition, the sale process for IB1001, a recombinant factor IX (rFIX) for the treatment and prevention of bleeding in patients with hemophilia B is separate and in the final bidding stage.
As Inspiration's only senior secured creditor and as the owner of non-Inspiration assets that will be included in the sale of both OBI-1 and IB1001, Ipsen will receive approximately 60% of the upfront payments. Over and above these upfront amounts, Ipsen will receive 80% of all payments up to a present value of $304 million and 50% of all proceeds thereafter.
Evercore Partners served as exclusive financial advisor to Inspiration and Ipsen on the transaction.
