The Pioneer: Teva and the Original Brand Copaxone
Teva Pharmaceutical Industries Ltd. developed and initially marketed glatiramer acetate under the brand name Copaxone. Approved in the late 1990s, the 20 mg/mL daily injection became a standard treatment for relapsing forms of multiple sclerosis (MS). Teva later introduced a 40 mg/mL injection taken three times a week for convenience. The company also offered patient support through its Shared Solutions program, including injection training and financial assistance.
The Market Opens: Generic Competition Arrives
Patent expirations and challenges allowed generic manufacturers to enter the glatiramer acetate market, increasing competition and access.
Sandoz: A Key Generic Manufacturer
Sandoz, the generics division of Novartis, in collaboration with Momenta, launched Glatopa, a fully substitutable generic for Copaxone. Approved in both 20 mg/mL and 40 mg/mL doses, Glatopa provides a lower-cost option. Sandoz supports patients with GlatopaCare, offering services similar to the brand-name product's program.
Viatris (formerly Mylan): Another Significant Producer
Viatris, formed by the merger of Mylan and Upjohn, is another major generic glatiramer acetate manufacturer. Mylan obtained FDA approval for its generic version of both the 20 mg/mL and 40 mg/mL doses. Their product is notable for including the WhisperJECT® autoinjector, and patient support is available through the Viatris Advocate program.
Additional Manufacturers: Zydus and Synthon
The market continues to expand with other generic manufacturers. Zydus Lifesciences, working with Chemi S.p.A., received FDA approval for its generic glatiramer acetate injection in May 2025. Synthon Pharmaceuticals has also received FDA approval for a generic version, further diversifying supply and potentially lowering costs.
