EISAI ENTERS INTO COMPREHENSIVE CHINESE MARKETING AGREEMENT CONCERNING BREAST CANCER AND PARKINSON'S DISEASE TREATMENTS

Eisai Co., Ltd. (Headquarters: Tokyo, President & CEO: Haruo Naito, “Eisai”) announced today that it has entered into a comprehensive marketing agreement with Orion Corporation (Headquarters: Espoo, Finland; President & CEO: Timo Lappalainen, “Orion”) concerning Orion's breast cancer drug Fareston® (toremifene citrate) and its Parkinson’s disease treatment Eldepryl® (selegiline hydrochloride).

Under the terms of the agreement, Eisai shall acquire from Orion the exclusive rights to market the two products in China, and will distribute them through its Chinese subsidiary Eisai China Inc. (Suzhou, Jiangsu Province). Both drugs were previously marketed in China by a local distributor, however, marketing rights were transferred to Eisai China Inc. following the expiration of the contract between the distributor and Orion in early June 2011.

Fareston® is indicated for the treatment of metastatic breast cancer in postmenopausal women with estrogen receptor positive or unknown tumors and is commonly used as an adjuvant therapy in postmenopausal breast cancer. Eldepryl® is used in combination with levodopa-containing agents to treat Parkinson's disease in patients who have previously had an inadequate response to treatment with levodopa therapies alone.

Eisai China Inc. will establish a new presence in China the area of women's oncology by marketing Fareston®, and with the addition of Eldepryl®, will further enhance its lineup of neurology products, which currently includes the anti-Alzheimer’s agent Aricept® and the peripheral neuropathy treatment Methycobal®, as it seeks to make further contributions to address the diversified needs of and increase the benefits provided to breast cancer and Parkinson's disease patients in China.
