Synvisc Approved in Japan, Key Market for Viscosupplementation Products

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Genzyme Corporation (Nasdaq: GENZ) announced today that Japan’s Ministry of Health, Labour and Welfare has approved Synvisc® (hylan G-F 20; 3 x 2 mL), indicated for the treatment of osteoarthritis of the knee. Reimbursement has been obtained and publicized by Japan’s Central Social Insurance Medical Council.

According to a recent Japanese epidemiological study (ROAD), nearly 30 million people in Japan have osteoarthritis (OA) of the knee. The existing viscosupplements on the market in Japan require a greater number of injections than Synvisc, and may offer a much shorter duration of pain relief. Synvisc, the first non-Japanese viscosupplement to be approved in the country, will be the only product to offer six months of OA knee pain relief with three injections. Genzyme plans to launch Synvisc in Japan by the end of this year.

Genzyme has entered into an agreement with Teijin Pharma Limited to commercialize Synvisc in Japan. Under the terms of the agreement, Teijin Pharma has exclusive commercialization rights for Synvisc in Japan, and will pay certain milestone payments and a predetermined supply price for the product. Teijin Pharma, a division of the multinational Teijin Group, has extensive commercial experience in the orthopaedic market in Japan through its active promotion of products for bone and joint health.

“Launching Synvisc in Japan supports the growth of the franchise globally,” said Alison Lawton, Senior Vice President and General Manager of Genzyme Biosurgery, the business unit of Genzyme that manufactures and markets Synvisc. “Teijin Pharma’s expertise in the Japanese orthopaedic arena gives us confidence that they will successfully launch Synvisc and gain market share.”

“The viscosupplement market in Japan is valued at more than $500 million and there is increasing demand for new treatment options,” said Osamu Nishikawa, President of Teijin Pharma Limited. “Doctors and patients will be pleased to have a new product available that provides OA knee pain relief with just three injections rather than multiple injection products which are currently on the market. We look forward to utilizing our extensive marketing and sales experience in the orthopaedics space to offer physicians and patients this therapeutic option.”

About Synvisc

Synvisc® (hylan G-F 20) is indicated for the treatment of pain in osteoarthritis (OA) of the knee in patients who have failed to respond adequately to conservative nonpharmacologic therapy and simple analgesics, e.g., acetaminophen.

Important Safety Information

Synvisc is contraindicated in patients with known hypersensitivity to hyaluronan products and in patients with infections in or around the target knee. Do not inject Synvisc extra-articularly, into the synovial tissues, into the fat pad or joint capsule, or intravascularly. The safety and efficacy of Synvisc in locations other than the knee, or for conditions other than osteoarthritis, or in combination with other intraarticular injectables have not been established. Use caution when using Synvisc in patients allergic to avian proteins, feathers, or egg products; who have evidence of lymphatic or venous stasis in the leg to be injected; or who have severe inflammation in the knee to be treated. Strict adherence to aseptic technique must be followed. Remove any synovial fluid or effusion before each Synvisc injection. Patients should be advised to avoid strenuous or prolonged weight-bearing activities for approximately 48 hours after treatment. The safety and effectiveness of Synvisc in children and in pregnant or lactating women have not been established. It is unknown whether Synvisc is excreted in human milk.

In clinical trials, the most commonly reported adverse events were transient local pain, swelling, and/or effusion in the injected knee. In some cases, these symptoms have been extensive. The most commonly reported systemic side effects were rash, fever, nausea, and headache.

About Viscosupplementation

Viscosupplementation is a treatment for patients with osteoarthritis (OA) in which hyaluronic acid is injected into the knee joint to replace degraded joint fluid. Normal joint fluid can act as a lubricant and a shock absorber. Viscosupplementation is an accepted therapy for OA pain that is both comparable to oral therapies, yet avoids toxicity and the associated risks of systemic therapy. This procedure is performed on an out-patient basis and requires little recovery time.
