REVLIMID® and VIDAZA® Combination Therapy Achieves Nearly 30 Percent Complete Response in Untreated Elderly Patients with Acute Myeloid Leukemia

BOUDRY, Switzerland--(BUSINESS WIRE)--Dec. 10, 2012-- Celgene International Sàrl (NASDAQ: CELG) today announced that results from a study evaluating the combination of REVLIMID (lenalidomide) plus VIDAZA (azacitidine) in patients 60 years or older with untreated acute myeloid leukemia (AML) were presented at the American Society of Hematology annual meeting in Atlanta, GA.

In the phase II investigator-initiated study, patients received azacitidine 75 mg/m2/day, days 1-7 followed by lenalidomide 50 mg/day, days 8-28 of 42-day cycles. Treatment was continued until disease progression, unacceptable adverse event or completion of 12 cycles.

With 42 patients enrolled in the study, the overall response rate was 41%, with 28% of patients achieving a complete response (CR/CRi). The median time to CR and CRi was 12 and 6 weeks, respectively; the median duration of response (CR/CRi/PR) was 28 weeks (range 6 to >104 weeks). Median overall survival for all patients in the study was 20 weeks (range 1 to >121 weeks) and 69 weeks (range 10 to >121 weeks) for patients who responded to therapy. Additionally, median overall survival for responders was superior to non-responders (69 vs. 15 weeks p<0.01).

Most common adverse events were grade 1-2 and gastrointestinal in nature. There was one case each of grade 3 fever, sepsis, hyponatremia, pneumonitis and SIRS syndrome.

A three-arm phase II study in elderly AML patients is currently underway evaluating azacitidine monotherapy, azacitidine followed by lenalidomide (50 mg), and lenalidomide monotherapy.

These data are from an investigational study. REVLIMID® plus VIDAZA® is not approved for the treatment of acute myeloid leukemia.

About REVLIMID®

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 United States, Canada, Switzerland, Australia, New Zealand 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 Authorization Applications are currently being evaluated in a number of other countries.

Since 1998, Celgene continues to be a pioneer in creating environments in which patients can benefit from our disease-altering therapies safely. As a result, hundreds of thousands of patients worldwide have accessed the clinical benefits of our therapies through our performance-based risk management programs including, S.T.E.P.S.®, RevAssist® and RevMate®, which form the foundation of our commitment to patient safety.

U.S. Regulatory Information for Revlimid

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

REVLIMID® (lenalidomide) is indicated for the treatment of 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

 

WARNING: FETAL RISK, HEMATOLOGIC TOXICITY, and DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM

 

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.

HEMATOLOGIC TOXICITY (NEUTROPENIA AND THROMBOCYTOPENIA)

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)

 

DEEP VEIN THROMBOSIS AND PULMONARY EMBOLISM

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.

IMPORTANT SAFETY INFORMATION

About VIDAZA®

In December 2008, VIDAZA became the first and only drug approved by the European Commission to demonstrate a significant extension of overall survival compared to conventional care regimens, for patients with intermediate-2 and high-risk MDS and AML (20-30% blasts). Earlier in 2008, the U.S. FDA also included this extension of overall survival in its approved VIDAZA indication for treatment of all five French, American, British (FAB) MDS subtypes, which includes both low-risk and high-risk patients. These subtypes include: refractory anemia (RA), refractory anemia with ringed sideroblasts (RARS) if accompanied by neutropenia, or thrombocytopenia or requiring transfusions, refractory anemia with excess blasts (RAEB), refractory anemia with excess blasts in transformation (RAEB-T), and chronic myelomonocytic leukemia (CMML). The more recent WHO classification system incorporates RAEB-T patients within the AML category. VIDAZA has received orphan drug designation in several markets including the European Union, the U.S. and Japan.

VIDAZA® (azacitidine for injection) is indicated for treatment of patients with the following French-American-British (FAB) myelodysplastic syndrome subtypes: refractory anemia (RA) or refractory anemia with ringed sideroblasts (RARS) (if accompanied by neutropenia or thrombocytopenia or requiring transfusions), refractory anemia with excess blasts (RAEB), refractory anemia with excess blasts in transformation (RAEB-T), and chronic myelomonocytic leukemia (CMMoL).

About Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a cancer of myeloid blood cells that often transforms from MDS upon disease progression. AML is the proliferation of abnormal cells that accumulate in the bone marrow and interfere with the production of all types of normal blood cells (multi-lineage dysplasia). AML has traditionally been treated with high intensity chemotherapy, which is poorly tolerated by the majority of the patients who are afflicted – the elderly. Many of these patients may go untreated, and because they are ineligible for curative therapy, life expectancy is short and often measured in weeks to months.
