New Drug Application Approval in Japan for Copaxone® Subcutaneous Injection 20 mg Syringe, a Drug for the Treatment of Multiple Sclerosis
Developed by Teva Pharmaceutical Industries Ltd. (Teva), Copaxone® is a subcutaneous injection administered once daily to prevent the relapse of multiple sclerosis. Copaxone® is one of the most frequently-used drugs in multiple sclerosis therapy and is approved in more than 50 countries worldwide.
In Japan, glatiramer acetate was developed as an Unapproved New Drug by Teva Pharmaceutical K.K., a wholly owned subsidiary of Teva, at the request of the Japanese Ministry of Health, Labour and Welfare. In March, 2013, Takeda and Teva signed a licensing agreement in which Teva granted Takeda the right to commercialize glatiramer acetate in Japan. Takeda submitted the NDA in December 2014 under the terms of this agreement.
The approval is based on the safety and efficacy results of an open-label, 52-week clinical trial conducted in Japan by Teva Pharmaceutical K.K. in patients with relapsing-remitting multiple sclerosis as well as 3 clinical trials from overseas conducted by Teva in patients with relapsing-remitting multiple sclerosis.
Granting of this approval in Japan represents an extremely important milestone for Takeda, and we expect that this drug, which is the first-line therapy overseas for relapsing-remitting multiple sclerosis, can contribute to the therapy of Japanese patients with multiple sclerosis. We will continue to make efforts to deliver drugs that are needed by patients and healthcare professionals.

About Multiple Sclerosis
Multiple sclerosis is believed to be an autoimmune disease, the cardinal sign of which is inflammatory demyelination of the central nervous system characterized by demyelinating plaques in the brain and the spinal cord. Common symptoms include visual problems, ocular motor abnormality, paresthesia, muscle weakness, spasticity, urinary dysfunction, and cognitive impairment. The disease is categorized into three types: (1) a primary progressive type which takes a chronic progressive course from the onset, (2) a relapsing-remitting type which repeats a relapse and remission, and (3) a secondary progressive type which shifts to the progressive course later. More than 80% of patients are categorized into the relapsing-remitting type. The morbidity in patients is estimated to be approximately 18,000 in Japan, and its prevalence shows an increasing trend.
