Teva Pharmaceutical Industries Ltd. said that a new version of its
multiple sclerosis drug Copaxone met its goals in a late-stage clinical
trial.....
We know that, COPAXONE is the brand name for glatiramer acetate (formerly known as copolymer-1). Glatiramer acetate, the active ingredient of COPAXONE (glatiramer acetate) , consists of the acetate salts of synthetic polypeptides, containing four naturally occurring amino acids: L-glutamic acid, L-alanine, L-tyrosine, and L-lysine with an average molar fraction of 0.141, 0.427, 0.095, and 0.338, respectively. The average molecular weight of glatiramer acetate is 5,000 – 9,000 daltons. Glatiramer acetate is identified by specific antibodies.

Chemically, glatiramer acetate is designated L-glutamic acid polymer with L-alanine, L-lysine and L-tyrosine, acetate (salt). Its structural formula is:
(Glu, Ala, Lys, Tyr)x•xCH3COOH
(C5H9NO4•C3H7NO2•C6H14N2O2•C9H11NO3)x•xC2H4O2
CAS - 147245-92-9
COPAXONE (glatiramer acetate) is a clear, colorless to slightly yellow, sterile, nonpyrogenic solution for subcutaneous injection. Each 1 mL of solution contains 20 mg of glatiramer acetate and 40 mg of mannitol. The pH range of the solution is approximately 5.5 to 7.0. The biological activity of COPAXONE (glatiramer acetate) is determined by its ability to block the induction of experimental autoimmune encephalomyelitis (EAE) in mice.
