Adds Next Generation Small Molecule Anticoagulant Reversal Agent to Development Pipeline to Leverage AMAG’s Expertise in Hematology
WALTHAM, Mass., Jan. 17, 2019 (GLOBE NEWSWIRE) -- AMAG Pharmaceuticals, Inc. (NASDAQ:AMAG) announced today that it has completed the previously announced acquisition of Perosphere Pharmaceuticals Inc., a private biopharmaceutical company. Through this acquisition, AMAG adds ciraparantag to its development portfolio. Ciraparantag is in development as a single dose, ready-to-use solution for use in patients treated with novel oral anticoagulants (NOACs) or low molecular weight heparin (LMWH) when reversal of the anticoagulant effect of these products is needed for emergency surgery, urgent procedures or due to life-threatening or uncontrolled bleeding. It is believed that ciraparantag exerts its effects by binding to and blocking the effects of NOACs such as Xarelto®(rivaroxaban), Eliquis®(apixaban) and Savaysa®(edoxaban), as well as to the LMWH Lovenox® (enoxaparin sodium injection), which in turn reestablishes normal clot formation. Ciraparantag has been granted Fast Track review designation by the U.S. Food and Drug Administration (FDA) and has composition of matter patent protection until 2034.
“This acquisition represents a great strategic fit and a unique opportunity to add an innovative, durable and differentiated clinical asset to our portfolio,” said William Heiden, AMAG’s president and chief executive officer. “NOAC therapy represents the fastest-growing segment of the anticoagulant market in the U.S., and there are approximately 15 million people worldwide on NOAC or LMWH therapy. Unfortunately, patients taking anticoagulants are at an increased risk for serious bleeding complications. In Phase 2 clinical trials, ciraparantag has been shown to rapidly reverse the anticoagulant effects of three widely prescribed NOACs and a LMWH, and the effect was sustained for up to 24 hours.”
AMAG plans to hold an end of Phase 2 meeting with the FDA later this year to confirm the design of the Phase 3 program, which is expected to include Phase 3a trials in healthy volunteers followed by a Phase 3b/4 trial in patients. The company intends to initiate the Phase 3a trials in the second half of 2019. Ciraparantag has been well tolerated in clinical trials. To date, the most common adverse events related to ciraparantag have been mild sensations of coolness, warmth or tingling, skin flushing, and alterations in taste.
Provided certain clinical milestones are met, the Phase 3 program will be partially funded by an existing agreement with a global pharmaceutical company, which does not currently have commercialization rights to ciraparantag. In addition, as part of the Phase 3 program, AMAG plans to utilize an automated coagulometer, currently being developed by an independent company, Perosphere Technologies Inc.
At closing, AMAG paid the Perosphere equityholders $40 million in cash consideration (subject to customary purchase price adjustments) net of approximately $10 million due to AMAG under a convertible note that Perosphere issued to AMAG in October 2018. AMAG also repaid $12 million of Perosphere’s term loan indebtedness and assumed $6.2 million of Perosphere’s other liabilities.
Perosphere equityholders will be eligible to receive regulatory milestones of up to $140 million, inclusive of a $40 million milestone payment upon approval by the European Medicines Agency, if the final U.S. label has no boxed warning. Perosphere equityholders are also eligible to receive commercial sales milestone payments of up to an aggregate of $225 million. The first sales milestone payment of $20 million would be payable upon achieving annual net sales of $100 million.
On January 7, 2019, AMAG provided 2019 financial guidance for revenue, operating loss and adjusted EBITDA, which remains unchanged.
