BOUDRY, Switzerland, Jun 04, 2010 (BUSINESS WIRE) --Celgene International Sàrl (NASDAQ:CELG) today announced that initial data from an investigator-initiated study of REVLIMID (lenalidomide) plus Rituxan (rituximab) in patients with newly diagnosed indolent B-cell non-Hodgkin's lymphoma (NHL) were presented at the annual meeting of the American Society of Clinical Oncology.
Patients in the study had previously untreated indolent NHL with stage III or IV measurable (>1.5 cm) disease. Of 30 patients for whom FLIPI (Follicular Lymphoma International Prognostic Index) scores were available, 87% of patients were classified as either intermediate or high risk, and 73% of patients had positive bone marrow involvement. Patients were treated with 20 mg/day of lenalidomide on days 1-21 of a 28-day cycle and 375 mg/m2 of rituximab on day 1 of each cycle for up to 6 cycles.
Results from the Phase II single-arm study reported that of 45 evaluable patients, the overall response rate was 89% (40/45), with 73% (33/45) of patients achieving a complete response (defined as CR or CRu). In a subset of 29 evaluable patients with follicular lymphoma, 97% (28/29) responded to therapy, including 86% (25/29) of patients who achieved a complete response. At a median follow-up of 12 months (range, 3-20), one patient has progressed.
The most common grade 3 or 4 adverse events experienced by patients in the study were neutropaenia (21% 10/45), rash (13% 6/45), and myalgia (8% 4/45). The rash was generally found to be self-limited and usually did not occur on re-exposure to the drug. Three patients were removed from treatment due to an adverse event related to one or both of the study drugs but were eligible for toxicity assessment and included 1 with rash and 1 with arterial thrombosis, both of which occurred during cycle 1. The third patient developed a severe reaction to rituximab prior to lenalidomide dosing during cycle 2.
These data are from an investigational study. REVLIMID® does not have marketing approval for the treatment of patients with untreated indolent B-cell NHL.
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 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 myelodysplastic syndromes (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.
REVLIMID(lenalidomide) in combination with dexamethasone is indicated for the treatment of multiple myeloma patients who have received at least one prior therapy.
REVLIMID (lenalidomide) is indicated for patients with transfusion-dependent anaemia due to low- or intermediate-1-risk MDS associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities.
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. HAEMATOLOGIC TOXICITY (NEUTROPAENIA AND THROMBOCYTOPAENIA).
This drug is associated with significant neutropaenia and thrombocytopaenia.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 haematologic 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 non-Hodgkin's lymphoma
Lymphoma is the name for the group of blood cancers that start in the lymphatic system, which is part of the body's immune system. Lymphomas generally start in the lymph nodes or outside of lymph nodes within lymphatic tissues located in organs such as the stomach or intestines. They may involve the marrow and the blood in some cases as well. There are many different kinds of non-Hodgkin's lymphoma (NHL). There are an estimated 360,000 patients with NHL in the U.S. with more than 63,000 new patients diagnosed annually.
