Pfizer, Inc. and Synthon, have entered into an agreement whereby Pfizer has acquired the exclusive commercialization rights in the United States to glatiramer acetate, a potential generic version of the originator medicine Copaxone® for the treatment of relapsing remitting multiple sclerosis (RRMS).

In November 2011, Synthon filed an Abbreviated New Drug Application (ANDA) with the U.S. Food and Drug Administration (FDA) for a once daily 20mg/ml formulation of glatiramer acetate. In early 2014, Synthon filed an ANDA for a three-times-a-week 40mg/ml formulation of glatiramer acetate with the FDA. In addition, Synthon believes its glatiramer acetate 40mg/ml filing may be eligible for 180 days of shared marketing exclusivity under the provisions of the Hatch-Waxman Act.

Under the terms of the agreement, Pfizer will have exclusive rights to commercialize both dosage formulations of Synthon’s glatiramer acetate in the United States. Synthon is responsible for the clinical development, manufacture and supply of glatiramer acetate. Pfizer is solely responsible for the commercialization of glatiramer acetate in the United States. Financial terms of the agreement were not disclosed.
