Chugai and Maruho Announce the Launch of
"Marduox® Ointment," for Psoriasis Vulgaris
(Combination Topical Ointment)

TOKYO, June 21, 2016 -- Chugai Pharmaceutical Co., Ltd. (TOKYO: 4519) and Maruho Co., Ltd. announced today that both companies launched "Marduox® Ointment" (Marduox) for the indication of psoriasis vulgaris, which had been jointly developed by Chugai and Maruho, and acquired the marketing approval in March 2016.

Marduox is a topical preparation combining maxacalcitol, an active vitamin D3 derivative developed by Chugai, and the corticosteroid betamethasone butyrate propionate. Both drugs are indicated for psoriasis vulgaris and are clinically used individually or together for the treatment of the disease. Marduox had been developed as an easy-to-use combination drug that leverages the advantages of these drugs and at the same time improves the issues associated with concomitant uses of multiple topical drugs.

The collaboration between Chugai and Maruho started with the launch of “Oxarol® Ointment 25μg/g” in 2001, which contains maxacalcitol as an active ingredient, and followed by the launch of “Oxarol® Lotion 25μg/g” in 2007. Maruho has marketed these drugs.

Maruho which specializes in the dermatology area and Chugai, the originator of this product, are convinced that Marduox will provide better treatment for patients suffering from psoriasis vulgaris.

About psoriasis

Psoriasis is a chronic skin disease classified under the inflammatory keratosis category. It is a disease having two aspects: inflammation of the skin and abnormal metabolism of the epidermis (the outermost layer of the skin). It is divided into five types according to symptoms, and approximately 90% of cases are psoriasis vulgaris. In Japan, 430,000 people, accounting for 0.3% of the population, are reported to be affected. As a typical symptom, silver-white scales resembling thin scabs are attached to red-colored eruptions elevated slightly from the skin, and these scales flake off like dandruff. In Japanese, psoriasis is called kansen, which phonetically can also mean “infection or infectious disease.” Thus, psoriasis is often misunderstood to be infectious. However, it is not a contagious disease. It is a chronic disease, and difficult to be cured with currently available treatment. Topical medicine and other drugs are mainly used to control the symptoms.
