R-Pharm Group To Launch Glatirat, an Analogue of Copaxone for MS Treatment
The Russian Ministry of HealthĀ recently granted Marketing Authorization (ŠŠ-003567) to R-Pharm JSC for the development of Ā āGlatiratā (Glatiramer acetate), a drug intended for the treatment of patients with relapsing-remitting multiple sclerosis (RRMS) and clinically isolated syndrome. According to a press release, the registration of āGlatiratā was based on a collaboration between R-Pharm and the generics developer company Synthon.Ā Glatirat is an injectable equivalent of Copaxone.
Copaxone (Teva Pharmaceuticals) is an immunomodulatorĀ drug currently used to treatĀ multiple sclerosis Ā (MS) and RRMS. It is a random polymer of four amino acids found inĀ myelin basic protein, namelyĀ glutamic acid,Ā lysine,Ā alanine, andĀ tyrosine, and may work as a decoy for the immune system. Glatiramer acetate reduces the frequency of relapses.
Glatirat is equivalent to Copaxone in all key parameters: it has the same efficacy and safety, strength and administration route, as well as the same physical and chemical properties, potency (biological activity) and quantitative and qualitative composition.
The research program for āGlatiratā was the broad-scaleest in the world among programs for the development of glatiramer acetate analogues. A Phase 1 study was conducted in healthy volunteers, and a Phase 3Ā study was conducted inĀ patients with MS. Worldwide, approximately 800 people have received Glatirat injections.
The large-scale, multicenter Phase 3Ā clinical trial, called GATE (Glatiramer Acetate clinical Trial to assess Equivalence to CopaxoneĀ®) was the only Phase 3Ā study conducted with a generic version of CopaxoneĀ®. Results from the study, which included 188 Russian patients treated forĀ 24 months in 23 leading centers of the Russian Federation, demonstrated an equivalent efficacy and safety profile for glatiramer acetate compared to CopaxoneĀ®.
The double-blind part of GATE showed the therapeutic equivalence between Glatirat and Copaxone. Efficacy analysis performed during the study showed that Glatirat was similar to CopaxoneĀ in all key parameters. In terms of safety profile, Glatirat was found to be comparable to CopaxoneĀ in terms of adverse events and tolerance. The open part of GATEĀ assessedĀ the long-term safety and efficacy of Glatirat. The results showedĀ that the efficacy and safety of the therapy does not change when patients are switchedĀ from CopaxoneĀ to Glatirat.
Results from this study were presented in 2014 and 2015 at the ECTRIMS congress, and published in 2015 in the journal JAMA Neurology.Ā In April 2016, Glatirat was approved in 28 European Union countries.Ā
The drug will be manufactured at the State-of-the-art Manufacturing Site of R-Pharm JSC in Yaroslavl.Ā In 2015, glatiramer acetate was included into the Russian List of life-saving and essential medical drugs.
