Celgene Announces New Drug Application Filing for REVLIMID® in Japan

REVLIMID filing based on safety and efficacy results of two large, randomised pivotal Phase III trials, as well as specific Japanese studies

NDA is for REVLIMID in combination with dexamethasone for multiple myeloma patients who have received at least one prior therapy

BOUDRY, Switzerland--(BUSINESS WIRE)--Celgene International Sàrl (NASDAQ:CELG) today announced it has filed a New Drug Application (NDA) with the Japanese Ministry of Health, Labour and Welfare (MHLW) for REVLIMID (lenalidomide) in combination with dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy. Approximately 11,000 people in Japan suffer from multiple myeloma and around 4,000 patients are diagnosed each year.

"The filing of an NDA in Japan for multiple myeloma represents an important step towards achieving our goal of delivering REVLIMID to patients in need in one of the world's largest oncology populations," said Joseph Melillo, General Manager of Celgene KK.

The filing with the MHLW is based upon the safety and efficacy results of two large, randomised pivotal Phase III special protocol assessment trials: North American Trial MM-009 and International Trial MM-010 evaluating REVLIMID plus dexamethasone in multiple myeloma patients who have received at least one prior therapy. Both studies were published in the New England Journal of Medicine in November 2007. Phase I clinical results with Japanese patients, including those from MM-017, confirm similar efficacy and further support the filing.

REVLIMID was granted orphan drug status in February 2008 by the MHLW in Japan for two indications - the treatment of anaemia due to low- or intermediate-1-risk myelodysplastic syndromes (MDS) associated with a deletion 5q cytogenic abnormality with or without other cytogenic abnormalities, and in combination with dexamethasone for multiple myeloma patients who have received at least one prior therapy.

REVLIMID is approved in combination with dexamethasone for the treatment of patients with multiple myeloma who have received at least one prior therapy in nearly 50 countries, encompassing Europe, the Americas, the Middle-East and Asia, and in combination with dexamethasone for the treatment of patients whose disease has progressed after one therapy in Australia and New Zealand.

REVLIMID® is also approved in the United States, Canada and several Latin American countries, as well as Malaysia and Israel, for transfusion-dependent anaemia due to low- or intermediate-1-risk MDS associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities. Marketing Authorisation Applications are currently being evaluated in a number of other countries.

About Multiple Myeloma

Multiple myeloma (also known as myeloma or plasma cell myeloma) is a cancer of the blood in which malignant plasma cells are overproduced in the bone marrow. Plasma cells are white blood cells that help produce antibodies called immunoglobulins that fight infection and disease. However, most patients with multiple myeloma have cells that produce a form of immunoglobulin called paraprotein (or M protein) that does not benefit the body. In addition, the malignant plasma cells replace normal plasma cells and other white blood cells important to the immune system. Multiple myeloma cells can also attach to other tissues of the body, such as bone, and produce tumors. The cause of the disease remains unknown.
