Launch of Bonalon® Tablet 35 mg, Ethical Drug for the Treatment of Osteoporosis

Teijin Pharma Limited

Tokyo, Japan, September 15, 2006, - Teijin Pharma Limited (head office: Chiyoda-ku, Tokyo. President: Shigeo Oyagi) announced today that its new product Bonalon® Tablet 35mg (Alendronate sodium hydrate), the Japan's first once-weekly drug for osteoporosis, was registered on the reimbursement (NHI) price list. The product was launched on the same day.

Osteoporosis is a chronic disease that is associated with bone fractures. It is estimated to affect 10 million Japanese. The major factors causing elderly patients to be bedridden are fractures and falls. Ongoing treatment is seen as an important means of addressing these factors and reducing the risk of fractures.

Teijin has been committed to developing a drug for osteoporosis for many years and has previously marketed two preparations with different mechanisms: Onealfa®, an active vitamin D3 preparation with a stimulatory effect on bone formation and Bonalon® Tablet 5mg, which has an inhibitory effect on bone resorption. With the launch of Bonalon® Tablet 35mg, Japan's first once-weekly drug for osteoporosis, Teijin makes a new contribution to pharmacotherapeutic advances in the treatment of osteoporosis.

Details of the product are as follows:


1. About alendronate sodium hydrate (abbreviated to alendronate)
1) Alendronate is the bisphosphonate compound. Teijin Pharma Limited obtained exclusive rights to develop and market alendronate in Japan from Gentili, Italy. Subsequently Teijin Pharma Limited and Merck & Co., Inc. U.S.A./Banyu Pharmaceutical Co., Ltd. jointly developed the product in Japan.
2) Alendronate has been proven to increase bone mineral density and reduce the incidence of femoral neck and vertebral fractures in osteoporosis patients with its potent inhibitory effect on bone resorption. Also, it is the only drug for which efficacy and safety have been shown in a long-term continuation study for at least 10 years.
3) Teijin launched Teiroc® Injection, a drug for hypercalcemia associated with malignant tumor, in 1997 and Bonalon® Tablet 5mg, a daily drug for osteoporosis, in 2001, both of which contain alendronate as an active ingredient. Teijin is now launching the Bonalon® Tablet 35mg, a once-weekly drug for osteoporosis.
4) The first approval of the once-weekly alendronate was given in Mexico in 2000. This was followed by 83 other countries as of April, 2006. It is now prescribed to more than 7 million patients each year worldwide.

2. About Bonalon® Tablet 35mg
Since the daily Bonalon® Tablet 5mg must be taken upon rising with a glass of plain water and patients cannot lie down at least for 30 minutes after intake, some patients have had difficulties adhering to the treatment regimen and have finally discontinued the drug.

A phase III double-blind comparison trial conducted in Japan showed that the efficacy of treatment with the once-weekly Bonalon® Tablet 35mg was equivalent and the safety was similar to treatment those with the once-daily Bonalon® Tablet 5mg. Therefore, Bonalon® Tablet 35mg will reduce the number of drugs that need to be taken to achieve the same therapeutic effects. This should in turn attenuate the burden on patients.

Features of Bonalon® Tablet 35mg
1) The once-weekly preparation for the treatment of osteoporosis
2) Decrease in the incidence of osteoporotic fractures(*)
*According to the results of clinical studies conducted inside and outside Japan
3) Increase in the bone mineral density of lumbar spine and total hip in osteoporosis patients.
-It showed the same efficacy as once-daily Bonalon® 5mg.
4) The incidence of adverse reactions was 13.1% (22/168 patients) and the abnormal clinical laboratory findings were 3.6% (6/168 patients).

3. Sales target
Teijin expects sales of more than three billion yen for the first year and peak sales of more than 20 billion yen combined with Bonalon® 5mg (more than 35 billion yen further combined with Onealfa®) in the future. These forecasts are based on the NHI price.

Bonalon® is the registered trademark of Merck & Co., Inc., Whitehouse Station, NJ, USA.
