|Teva Presents New Long-Term Data Demonstrating Efficacy and Safety of COPAXONE® (glatiramer acetate injection) 40 mg/mL|
Up to 7-year efficacy, safety and tolerability results from the GALA open-label extension study presented at the 70th Annual Meeting of the AAN
Over seven years, COPAXONE® 40 mg/mL provides consistent, long-term efficacy and safety
“The continued long-term efficacy, safety and tolerability observed in
the GALA open-label extension study is encouraging,” said
Efficacy analysis included exposure data from randomization until the last available observation for both the ES and DS groups (median glatiramer acetate exposure of 5.5 and 4.5 years, respectively). Annualized relapse rate for the entire long-term follow-up period since randomization was 0.26 for ES and 0.31 for DS groups (P=.041), and approximately 50% of patients were relapse-free in both groups. Time to first confirmed relapse was longer in ES vs DS patients (HR=0.815; 95% CI: 0.693-0.959); P=0.0135). Time to 6-month confirmed disability progression (CDP) and to EDSS 4.0 was similar between ES and DS groups, and approximately 81% of patients in both groups were free from 6-month CDP.
No new or unexpected adverse events emerged in patients receiving COPAXONE 40 mg/mL for up to 7 years. Adverse events were generally mild and consistent with the well-established safety profile of COPAXONE.

Important Safety Information about COPAXONE®
COPAXONE® is contraindicated in patients with known hypersensitivity to glatiramer acetate or mannitol.
Approximately 16% of patients exposed to COPAXONE® 20 mg per mL compared to 4% of those on placebo, and approximately 2% of patients exposed to COPAXONE® 40 mg per mL compared to none on placebo experienced a constellation of symptoms that may occur within minutes after injection and included at least 2 of the following: flushing, chest pain, palpitations, tachycardia, anxiety, dyspnea, throat constriction, and urticaria. In general, these symptoms have their onset several months after the initiation of treatment, although they may occur earlier, and a given patient may experience 1 or several episodes of these symptoms. Typically, the symptoms were transient and self-limited and did not require treatment; however, there have been reports of patients with similar symptoms who received emergency medical care.
Transient chest pain was noted in 13% of COPAXONE® 20 mg per mL patients compared to 6% of placebo patients, and approximately 2% of COPAXONE® 40 mg per mL patients compared to 1% on placebo. While some episodes of chest pain occurred in the context of the Post-Injection Reaction described above, many did not. The temporal relationship of this chest pain to an injection was not always known. The pain was usually transient, often unassociated with other symptoms, and appeared to have no clinical sequelae. Some patients experienced more than 1 such episode, and episodes usually began at least 1 month after the initiation of treatment.
At injection sites, localized lipoatrophy and, rarely, injection site skin necrosis may occur. Lipoatrophy may occur at various times after treatment onset (sometimes after several months) and is thought to be permanent. There is no known therapy for lipoatrophy.
Because COPAXONE® can modify immune response, it may interfere with immune functions. For example, treatment with COPAXONE® may interfere with recognition of foreign antigens in a way that would undermine the body’s tumor surveillance and its defenses against infection. There is no evidence that COPAXONE® does this, but there has not been a systematic evaluation of this risk.
In controlled studies of COPAXONE® 20 mg per mL, the most common adverse reactions with COPAXONE® vs placebo were injection site reactions (ISRs), such as erythema (43% vs 10%); vasodilatation (20% vs 5%); rash (19% vs 11%); dyspnea (14% vs 4%); and chest pain (13% vs 6%).
In a controlled study of COPAXONE® 40 mg per mL, the most common adverse reactions with COPAXONE® vs placebo were ISRs, such as erythema (22% vs 2%).
ISRs were one of the most common adverse reactions leading to discontinuation of COPAXONE®. ISRs, such as erythema, pain, pruritus, mass, edema, hypersensitivity, fibrosis, and atrophy, occurred at a higher rate with COPAXONE® than placebo.
