Celgene Provides Update on Regulatory Submissions

REVLIMID® (lenalidomide) Capsules Marketing Authorisation Application Submitted to EMA for Treatment of Newly Diagnosed Multiple Myeloma And Maintenance Therapy

ISTODAX® (romidepsin) for Injection Supplemental New Drug Application Submitted to U.S. FDA for Previously Treated Peripheral T-Cell Lymphoma

BOUDRY, Switzerland, Jan 04, 2011 (BUSINESS WIRE) --

Celgene International Sàrl (NASDAQ: CELG) announced regulatory submissions for its blood cancer therapies REVLIMID (lenalidomide) and ISTODAX (romidepsin).

The company submitted a Marketing Authorisation Application (MAA) for the approval of REVLIMID (lenalidomide) for maintenance treatment of newly diagnosed multiple myeloma patients who have not progressed following initial treatment with melphalan, prednisone and REVLIMID, or following autologous stem cell transplantation. The application was submitted with the European Medicines Agency (EMA) on December 31, 2010.

The MAA will be reviewed by the Committee for Medicinal Products for Human Use (CHMP). Review of each application will be conducted by the EMA under the centralised licensing procedure, which, when finalised, provides one marketing authorisation in all 27 member states of the European Union.

The application was based on the results of MM-015, an international, randomised pivotal phase III study. The submission is also supported by two additional PHASE III studies comparing continuous REVLIMID therapy following autologous stem cell transplant versus placebo. Unprecedented results from these phase III studies were presented at the American Society of Hematology Annual Meeting in December 2010.

In addition to the European submission for REVLIMID, a Supplemental New Drug Application (sNDA) was submitted to the U.S. Food and Drug Administration (FDA) on December 17, 2010 for ISTODAX in the treatment of patients with peripheral t-cell lymphoma (PTCL) who have received at least one prior therapy. The sNDA submission was based on a pivotal, phase II, multicenter, international, open-label study of romidepsin in patients with progressive or relapsed PTCL following prior systemic therapy.

The sNDA will now be reviewed for acceptance under current FDA guidelines.


REVLIMID is an IMiDs® compound. REVLIMID and other IMiDs continue to be evaluated in over 100 clinical trials. The IMiDs pipeline is covered by a comprehensive intellectual property estate of issued and pending patent applications in the US, EU and other regions, 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 70 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 Americas, the Middle-East and Asia 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.

REVLIMID® (lenalidomide) in combination with dexamethasone is indicated for the treatment of multiple myeloma (MM) patients who have received at least one prior therapy.

REVLIMID is indicated for patients with transfusion-dependent anemia due to Low- or Intermediate-1-risk myelodysplastic syndromes (MDS) associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities.

Important Safety Information


Do not use REVLIMID during pregnancy. Lenalidomide, a thalidomide analogue, caused limb abnormalities in a developmental monkey study. Thalidomide is a known human teratogen that causes severe life-threatening human birth defects. If lenalidomide is used during pregnancy, it may cause birth defects or death to a developing baby. In women of childbearing potential, obtain 2 negative pregnancy tests before starting REVLIMID treatment. Women of childbearing potential must use 2 forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after REVLIMID treatment. To avoid fetal exposure to lenalidomide, REVLIMID is only available under a restricted distribution program called "RevAssist®."

Information about the RevAssist program is available at www.REVLIMID.com or by calling the manufacturer's toll-free number 1-888-423-5436.


REVLIMID can cause significant neutropenia and thrombocytopenia. Eighty percent of patients with del 5q MDS 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 MDS 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)


REVLIMID has demonstrated a significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients with MM who were treated with REVLIMID and dexamethasone 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 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.

ISTODAX® (romidepsin) is a member of a new class of cancer drugs known as histone deacetylase (HDAC) inhibitors. HDACs catalyze the removal of acetyl groups from acetylated lysine residues in histones, resulting in the modulation of gene expression. HDACs also deacetylate non-histone proteins, such as transcription factors. HDAC inhibitors can be divided into four main classes: cyclic tetrapeptides (I), short-chain fatty acids (II), hydroxamic acids (III), and benzamides (IV). The cyclic peptide structure of ISTODAX is novel among the cyclic tetrapeptides. In vitro, ISTODAX causes the accumulation of acetylated histones, and induces cell cycle arrest and apoptosis of some cancer cell lines. For full prescribing information, visit www.ISTODAX.com.

ISTODAX is approved in the United States for the treatment of cutaneous T-cell lymphoma (CTCL) in patients who have received at least one prior systemic therapy.

Important Safety Information

ISTODAX is indicated for treatment of cutaneous T-cell lymphoma (CTCL) in patients who have received at least one prior systemic therapy.

Warnings and Precautions

Due to the risk of QT prolongation, potassium and magnesium should be within the normal range before administration of ISTODAX.

Treatment with ISTODAX can cause thrombocytopenia, leukopenia (neutropenia and lymphopenia), and anemia; therefore, these hematological parameters should be monitored during treatment with ISTODAX, and the dose should be modified, as necessary.

Several treatment-emergent morphological changes in ECGs including T-wave and ST-segment changes have been reported in clinical studies. The clinical significance of these changes is unknown. In patients with congenital long QT syndrome, patients with a history of significant cardiovascular disease, and patients taking anti-arrhythmic medicines or medicinal products that lead to significant QT prolongation, appropriate cardiovascular monitoring precautions, such as the monitoring of electrolytes and ECGs should be considered.

Based on its mechanism of action, ISTODAX may cause fetal harm. Woman should avoid becoming pregnant while being treated with ISTODAX and pregnant women should be advised of the potential harm to the foetus.

ISTODAX binds to estrogen receptors. Women of childbearing potential should be advised that ISTODAX may reduce the effectiveness of estrogen-containing contraceptives.

Adverse Reactions

Safety data are available from 185 patients with CTCL from two clinical trials. Adverse reactions are presented separately for each study due to methodological differences between the studies. The most common reported adverse reactions in Study 1 were nausea (56%), fatigue (53%), infections (46%), vomiting (34%), and anorexia (23%) and in Study 2 were nausea (86%), fatigue (77%), anemia (72%), thrombocytopenia (65%), ECG T-wave changes (63%), neutropenia (57%), and lymphopenia (57%). Most of the adverse reactions were reported to be mild or moderate in severity. Most deaths in the studies were due to disease progression. Discontinuation due to an adverse event occurred in 21% of patients in Study 1 and 11% in Study 2. Serious adverse reactions reported in > 2% of patients in Study 1 were infection, sepsis, and pyrexia. In Study 2, serious adverse reactions in > 2% of patients were infection, supraventricular arrhythmia, neutropenia, fatigue, edema, central line infection, ventricular arrhythmia, nausea, pyrexia, leukopenia, and thrombocytopenia.

Drug Interactions

Prothrombin time (PT) and International Normalized Ratio (INR) should be carefully monitored in patients concurrently administered ISTODAX and warfarin sodium derivatives.

Co-administration of strong CYP3A4 inhibitors may increase concentrations of ISTODAX and should be avoided.

Co-administration of potent CYP3A4 inducers may decrease concentrations of ISTODAX and should be avoided.

Caution should be exercised if ISTODAX is administered with drugs that inhibit P-glycoprotein.

Use in Specific Patient Populations

Patients with moderate and severe hepatic impairment or end-stage renal disease should be treated with caution.

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 tumours. The cause of the disease remains unknown.

About PTCL

Peripheral T-cell lymphoma comprises a heterogeneous group of lymphomas of T-cell origin, accounting for about 10-15% of all cases of non-Hodgkin's lymphoma. PTCL can occur at any age from young adulthood to old age and is slightly more common in men than in women. It is a particularly aggressive form of lymphoma with a short median duration of life expectancy (approximately two years) from diagnosis.
