Momenta Announces FDA Approval Of ANDA For Glatopa (Glatiramer Acetate Injection), The First Substitutable Generic For COPAXONE (Glatiramer Acetate Injection) 20mg

• First generic multiple sclerosis product approved in the United States
• Approval triggers $10 million milestone payment to Momenta

CAMBRIDGE, Mass., April 16, 2015 (GLOBE NEWSWIRE) -- Momenta Pharmaceuticals, Inc. (Nasdaq:MNTA), today announced that the U.S. Food and Drug Administration has granted marketing approval of Sandoz's Abbreviated New Drug Application for once daily Glatopa™ (glatiramer acetate injection, formerly M356) 20 mg/mL, a generic equivalent of daily COPAXONE^® 20 mg. Glatopa is the first substitutable generic indicated for the treatment of patients with relapsing-forms of multiple sclerosis (RRMS), a chronic disease of the central nervous system characterized by inflammation and neurodegeneration. Glatopa was developed under a collaboration agreement between Momenta and Sandoz and is the second complex generic developed by Momenta together with Sandoz to receive FDA approval. Glatopa will be commercialized under the Sandoz brand.

"We are proud to be able to offer patients with multiple sclerosis the first generic version of daily COPAXONE and the first generic product in this space," said Craig Wheeler, President and CEO, Momenta Pharmaceuticals. "The FDA approval of the ANDA for once daily Glatopa further validates Momenta's approach of using innovative physicochemical and biologic characterization to gain approval of complex generics, biosimilars and novel drugs, and advances Momenta's goal of expanding access to high quality, more affordable medicines."

Glatopa was determined by the FDA to be therapeutically equivalent to daily COPAXONE 20 mg, with the same active ingredients, route of administration, strength and dosage form. Glatopa's high quality U.S.-based supply chain and manufacturing process meets rigid FDA standards, and Glatopa is fully substitutable at the pharmacy level. Glatopa is expected to offer a more affordable treatment option for people living with RRMS.

Under the terms of its collaboration agreement with Sandoz, Momenta is eligible to receive up to $140 million in milestone payments upon the achievement of certain U.S. regulatory, commercial and sales-based milestones for Glatopa, including a $10.0 million payment earned upon sole FDA approval of the ANDA, and another $10.0 million milestone payment upon first commercial sale.

Sandoz is currently evaluating launch timing.

Momenta will host a conference call and webcast for investors today at 1:30 p.m. ET to discuss the approval of this important generic medicine. Conference call and webcast details will follow in a separate press release.

About Relapsing-Remitting Multiple Sclerosis (RRMS)

Multiple sclerosis is a devastating chronic disease of the central nervous system characterized by inflammation and neurodegeneration. RRMS, defined by inflammatory attacks on the protective coating of neurons (myelin) and characterized by intermittent bouts of symptoms, is the most common disease course at the time of diagnosis. COPAXONE is among the leading products marketed for treatment of RRMS. It works by stopping the body from damaging its own nerve cells (myelin). In North America, COPAXONE is marketed by Teva Neuroscience, Inc., which is a subsidiary of Teva Pharmaceuticals.
