The Medicines Company Announces Positive Phase III Trial Results for Fibrocaps; Completes ProFibrix Acquisition

The Medicines Company

announced the results of the pivotal Phase III clinical trial of ProFibrix's lead biologic, Fibrocaps, a dry powder topical formulation of fibrinogen and thrombin being developed to aid in hemostasis during surgery. The Phase III trial, FINISH-3, which studied a total of 719 patients, met all primary and secondary hemostasis efficacy endpoints in four distinct surgical indications of spinal surgery, hepatic resection, soft tissue dissection and vascular surgery. The Medicines Company expects the results of FINISH-3, which was conducted at 65 sites across the U.S. and Western Europe, to support a biologics license application (BLA) with the U.S. Food and Drug Administration, and a marketing authorisation application (MAA) with the European Medicines Agency. ProFibrix has also developed a complementary dry powder spray delivery device to assist surgeons in the accurate application of Fibrocaps. Recently the ProFibrix quality management system for the design, development and control of manufacture of sterile biological hemostat delivery systems and their accessories was granted ISO 14385: 2003 certification. Applications for a European CE mark and for an FDA 510k review for the device are underway. Dr. Kenneth L. Renkens, spine surgeon at the Indiana Spine Group and one of the Principal Investigators of FINISH-3, said, "The combined ease of use and efficacy of Fibrocaps have the potential to constitute an important advance in surgical hemostasis. Furthermore, the spray device could become an important tool to use in surgery and to apply Fibrocaps." As previously announced, The Medicines Company entered into an agreement with ProFibrix in June 2013 to purchase all of the equity of ProFibrix B.V. subject to its review of the results of the FINISH-3 trial. Based on its review, The Medicines Company purchased all of the outstanding equity of ProFibrix for $90 million at the closing held today and agreed to pay ProFibrix equityholders up to an additional $140 million upon the achievement of agreed-upon U.S. and European regulatory approvals and sales milestones. Clive Meanwell, Chairman and Chief Executive Officer of The Medicines Company said, "Subject to regulatory approval, we believe Fibrocaps can become an important hemostatic product -- complementary to Recothrom® (Thrombin, topical [Recombinant]). We anticipate leverage of our work with U.S. surgery centers and entry into the European market. Founded by leading fibrinogen expert Jaap Koopman, PhD, and led by Jan Öhrström, MD, who has extensive experience in this field, ProFibrix strengthens our global management team considerably. ProFibrix also has a proprietary recombinant fibrinogen development program which potentially allows us to create the world's first recombinant thrombin and recombinant fibrinogen combination products. We plan to integrate the ProFibrix team with our existing Recothrom team -- expanding our activities in surgery in pursuit of our purpose which is to save lives, alleviate suffering and improve the economic efficiency of leading hospitals worldwide." Jan Öhrström, MD, Chief Executive Officer of ProFibrix and former Senior Vice President of Development and Chief Medical Officer of ZymoGenetics, said, "It is clear to me that the ProFibrix team, Fibrocaps and our recombinant fibrinogen program are a natural fit with The Medicines Company's perioperative and hemostasis programs. Given the commitment of The Medicines Company to further build its surgery franchise, we are excited to be part of The Medicines Company and to help establish the Company as a leader in this field. With our Leiden site as a center for hemostasis at The Medicines Company, we look forward to the seamless integration of our Seattle and Leiden based teams and to continue the development of innovative hemostasis products." The Medicines Company anticipates peak Fibrocaps revenues of greater than $300 million if approved in major markets. The Company expects one time deal costs and incremental operating expenses, including transaction costs and amortization of intangibles to be approximately $9-12 million in the third quarter 2013. BofA Merrill Lynch served as financial advisor and WilmerHale served as legal advisor for the transaction for The Medicines Company. Barclays served as financial advisor and Dechert and Loyens & Loeff served as legal advisor for the transaction for ProFibrix. Index Ventures was ProFibrix's earliest investor; other investors included Gilde Healthcare Partners, Vesalius Biocapital and Inkef Capital. ABN AMRO also acted as an advisor to the company.
