SUMMIT, N.J., Aug 25, 2010 (BUSINESS WIRE) --
Celgene Corporation (NASDAQ: CELG) today announced that information was posted on the FDA Web site indicating that an Abbreviated New Drug Application (ANDA) has been received by the Office of Generic Drugs (OGD) containing a "Paragraph IV" patent certification, for REVLIMID (lenalidomide) 25 mg capsules. Celgene has not yet received the Paragraph IV notification letter identifying the filer.
Celgene intends to vigorously enforce its extensive intellectual property rights for REVLIMID and will file a complaint alleging infringement of Celgene patents after the notification letter is received. REVLIMID is currently protected by 12 issued patents listed in the FDA's Approved Drug Products List (Orange Book) and has additional patent applications pending. The issued patents cover REVLIMID's composition of matter, method of use, and polymorphs, as well as Celgene's RevAssist® system, the restricted distribution program as approved by the FDA. In order for the filer to prevail, the relevant patent claims must be deemed invalid, not infringed or expired.
The active ingredient of REVLIMID (lenalidomide) is an IMiDs® compound. Lenalidomide and other IMiDs compounds continue to be evaluated in over 100 clinical trials. The IMiDs pipeline is covered by a comprehensive intellectual property estate of U.S. and foreign issued and pending patent applications including composition-of- matter and use patents.
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, Israel, Japan, Australia and New Zealand for transfusion-dependent anemia due to low- or intermediate-1-risk MDS associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities. Marketing Authorization Applications are currently being evaluated in a number of other countries.
Important Safety Information
1. POTENTIAL FOR HUMAN BIRTH DEFECTS.
Lenalidomide is an analogue of thalidomide. Thalidomide is a known human teratogen that causes severe life-threatening human birth defects. If lenalidomide is taken during pregnancy, it may cause birth defects or death to an unborn baby. Females should be advised to avoid pregnancy while taking REVLIMID® (lenalidomide).
Male Patients:It is not known whether lenalidomide is present in the semen of patients receiving the drug.Therefore, males receiving REVLIMID® (lenalidomide) must always use a latex condom during any sexual contact with females of childbearing potential even if they have undergone a successful vasectomy.
Special Prescribing Requirements
Because of this potential toxicity and to avoid fetal exposure to REVLIMID® (lenalidomide), REVLIMID® (lenalidomide) is only available under a special restricted distribution program. In the U.S., this program is called "RevAssist®". Under this program, only prescribers and pharmacists registered with the program can prescribe and dispense the product. In addition, REVLIMID® (lenalidomide) must only be dispensed to patients who are registered and meet all the conditions of the RevAssist® program.
2. HEMATOLOGIC TOXICITY (NEUTROPENIA AND THROMBOCYTOPENIA).
This drug is associated with significant neutropenia and thrombocytopenia.Eighty percent of patients with del 5q myelodysplastic syndromes had to have a dose delay/reduction during the major study. Thirty-four percent of patients had to have a second dose delay/reduction. Grade 3 or 4 hematologic toxicity was seen in 80% of patients enrolled in the study. Patients on therapy for del 5q myelodysplastic syndromes should have their complete blood counts monitored weekly for the first 8 weeks of therapy and at least monthly thereafter. Patients may require dose interruption and/or reduction. Patients may require use of blood product support and/or growth factors. (see DOSAGE and ADMINISTRATION)
3. DEEP VENOUS THROMBOSIS AND PULMONARY EMBOLISM.
This drug has demonstrated a significantly increased risk of deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients with multiple myeloma who were treated with REVLIMID® (lenalidomide) combination therapy. Patients and physicians are advised to be observant for the signs and symptoms of thromboembolism. Patients should be instructed to seek medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. It is not known whether prophylactic anticoagulation or antiplatelet therapy prescribed in conjunction with REVLIMID® (lenalidomide) may lessen the potential for venous thromboembolic events. The decision to take prophylactic measures should be done carefully after an assessment of an individual patient's underlying risk factors.

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.
