AMAG PHARMACEUTICALS ENTERS INTO DEFINITIVE MERGER AGREEMENT TO ACQUIRE

PEROSPHERE PHARMACEUTICALS

 

Next Generation Anticoagulant Reversal Agent, Ciraparantag, Will Add Innovative

Clinical Stage Asset to AMAG’s Hematology Portfolio

 

Conference call scheduled for 8:00 a.m. ET today

 

WALTHAM, Mass. December 13, 2018 — AMAG Pharmaceuticals, Inc. (NASDAQ:AMAG) today announced it has entered into a definitive agreement to acquire Perosphere Pharmaceuticals Inc., a private biopharmaceutical company. Through this acquisition, AMAG will acquire global rights to ciraparantag, a next generation anticoagulant reversal agent, further enhancing its development pipeline and leveraging AMAG’s expertise in hematology. Ciraparantag is being investigated for 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. Ciraparantag has been granted Fast Track review designation by the U.S. Food and Drug Administration (FDA) and has patent protection through 2034.

 

“AMAG has been searching for a novel hematology asset to complement our existing portfolio and to leverage the expertise of our high performing Feraheme® hematology team,” said William Heiden, AMAG’s president and chief executive officer. “This acquisition represents a great strategic fit and a unique opportunity to add an innovative, durable and differentiated mid-phase clinical asset to our portfolio.”

 

Ciraparantag is a small molecule anticoagulant reversal agent which is believed to bind to NOACs such as Xarelto®(rivaroxaban), Eliquis®(apixaban) and Savaysa®(edoxaban), as well as to Lovenox® (enoxaparin sodium injection), a low molecular weight heparin, thereby reestablishing the body’s ability to form clots. Ciraparantag is in development as a single dose, ready-to-use solution that is delivered intravenously over approximately 10 minutes. NOAC therapy represents the fastest-growing segment of the anticoagulant market in the U.S. There are currently approximately six million patients in the U.S. and nine million patients in certain ex-U.S. countries on NOAC and LMWH therapy.(1) A recent study found that approximately 1.5-2% of patients taking certain NOACs were at risk for serious bleeding complications each year.(2)

 

“The number of patients on NOACs continues to grow and hundreds of thousands of these patients will experience or be at risk (e.g., urgent surgery) of a life-threatening bleed while on therapy,” said Dr. Jack Ansell, Professor of Medicine, Hofstra Northwell School of Medicine. “These patients often present in an emergency room setting where doctors have to act quickly, sometimes with incomplete patient information and limited

reliable treatment options. Therefore, if approved, I believe ciraparantag’s ability to rapidly normalize whole blood clotting time, as well as sustain this effect for up to 24 hours, will be extremely beneficial to patients, especially those in life threatening emergency situations. In addition, ciraparantag has not demonstrated any procoagulation signals, which is very reassuring given that this patient population is already at greater risk for clotting complications.”

 

In the Phase 2b clinical trials, ciraparantag was administered to healthy volunteers after achieving steady blood concentrations of Eliquis®, Xarelto®, Savaysa® and Lovenox®. In these studies, ciraparantag showed complete and sustained reversal of the anticoagulant effect of each drug studied by normalizing whole blood clotting time (WBCT), an important laboratory measure of clotting capacity. Subjects in these studies experienced a rapid and statistically significant (p<0.001) reduction in WBCT one hour after the administration of each of the three NOACs studied, as well as LMWH compared to placebo and the effect was sustained for 24 hours. Ciraparantag has been well tolerated in clinical trials. To date, the most common adverse events related to ciraparantag were mild sensations of coolness, warmth or tingling, skin flushing, and alterations in taste.

 

Over the past few years, AMAG has broadened and deepened its in-house clinical development focus and expertise,” said Julie Krop, M.D., chief medical officer and executive vice president of development at AMAG. “We are extremely excited to add ciraparantag to our portfolio. Based on its attractive product characteristics and promising clinical data, we believe it has the potential to positively impact patient care in this rapidly growing patient population. We look forward to working with the FDA to confirm the design of our Phase 3 program, which is expected to include a Phase 3a trial in healthy volunteers followed by a Phase 3b/4 trial in patients.”

 

Under the terms of the agreement, at closing AMAG will pay Perosphere equityholders $50 million (subject to customary adjustments) and will assume $12 million under a term loan and up to $6.2 million of Perosphere’s other liabilities.(3)

 

Perosphere equityholders will be eligible to receive regulatory milestones of up to $140 million (based on a final label with no boxed warning in the U.S.), inclusive of a $40 million milestone payment upon approval by the European Medicines Agency (EMA). Perosphere equityholders are also eligible to receive commercial sales milestone payments of up to an aggregate of $225 million. The first commercial sales milestone payment of $20 million would be payable upon achieving annual net sales of $100 million

 

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 a bedside coagulometer, currently being developed by Perosphere Technologies Inc.

 

The transaction is expected to close in the first quarter of 2019, subject to customary closing conditions.

 

The costs expected to be incurred in 2019 to advance this new pipeline asset do not change AMAG’s preliminary view of 2019 negative adjusted EBITDA of approximately $50 million, as previously disclosed on November 1, 2018. AMAG plans to issue 2019 guidance in early January.

 


(3)   AMAG was issued a $10 million convertible note from Perosphere as part of an exclusivity arrangement.  Proceeds to be offset from up-front consideration at closing.
