Momenta Pharmaceuticals, Inc. Presents Key Glatopa (Glatiramer Acetate Injection) Data At American Academy of Neurology Annual Meeting

CAMBRIDGE, Mass., April 20, 2015 (GLOBE NEWSWIRE) -- Momenta Pharmaceuticals, Inc. (Nasdaq:MNTA), a biotechnology company specializing in the characterization and engineering of complex drugs, today presented new data from studies conducted as part of the ANDA submission for once daily Glatopa (glatiramer acetate injection) at the 67th American Academy of Neurology (AAN) Annual Meeting in Washington D.C. The posters presented provide examples of a selection of methods the Company utilized to show the equivalence of Glatopa and once daily COPAXONE 20 mg.

Momenta Presentation Highlights:
Poster #P1.144 – Comparative Gene Expression Profiling between a Generic (Glatopa) and Brand COPAXONE (glatiramer acetate injection)

• Microarray analysis across the entire genome was performed in murine glatiramer acetate-responsive Th2-polarized T cells, a test system highly relevant to the biology of glatiramer acetate. Multiple statistical methods consistently demonstrated assay sensitivity as well as equivalent gene expression profiles between Glatopa and Copaxone.

Poster #P1.145 – Demonstration of Equivalence between a Generic (Glatopa) and Brand COPAXONE (glatiramer acetate injection)

• This poster summarized Momenta's overall approach of comparison, as well as multiple examples of equivalence of starting materials and basic chemistry; equivalence of structural manufacturing process signatures; equivalence of physicochemical (structural) properties; and equivalence of biological/immunological (functional) properties.

The selected assays and data presented at AAN are examples of the extensive physicochemical methods and biological/immunological assays that were submitted to the FDA as part of the recently approved data package for Glatopa.

"These posters not only provide examples of the comprehensive program we conducted to evaluate the equivalence of Glatopa and daily COPAXONE 20 mg, these data also further validate Momenta's ability to deeply characterize complex drugs and disease biologies and develop high-quality drugs," said Ganesh V. Kaundinya, Chief Scientific Officer of Momenta Pharmaceuticals.

About Glatopa^TM
Once daily Glatopa (glatiramer acetate injection), developed in collaboration with Sandoz, is the first FDA-approved generic version of daily COPAXONE® 20 mg for patients with relapsing forms of multiple sclerosis. Produced entirely in the United States, once daily Glatopa has been determined by the FDA to be therapeutically equivalent to daily COPAXONE 20 mg, and is an "AP" rated, fully-substitutable product. As a therapeutically equivalent generic product, once daily Glatopa contains the same active ingredients, route of administration, strength, and dosage form, and can be substituted with the full expectation that Glatopa will produce the same clinical effect and safety profile as daily COPAXONE 20 mg. Daily COPAXONE 20 mg is one of the leading products marketed to treat multiple sclerosis, and is frequently prescribed as a first-line therapy in newly diagnosed patients.
