Celgene Corporation (NASDAQ:CELG) today announced that data from FIRST (MM-020/IFM 07-01)—an open-label phase III randomized study of continuous REVLIMID (lenalidomide) in combination with dexamethasone in patients newly diagnosed with multiple myeloma (NDMM) who are not candidates for stem cell transplant—have been published in the Sept. 4 issue of the New England Journal of Medicine.
Initial findings, including that the trial had met its primary endpoint of progression free survival (PFS), were reported during the plenary session at the 55 th American Society of Hematology annual meeting in December 2013.
The findings, as published in the New England Journal of Medicine, demonstrated that at a median follow-up of 37 months among surviving patients, the median progression-free survival was 25.5 months with continuous oral lenalidomide plus low-dose
dexamethasone (Rd), 20.7 months with a fixed course of oral lenalidomide plus low-dose dexamethasone (Rd18) and 21.2 months with melphalan, prednisone and thalidomide (MPT). This resulted in a 28% reduction in risk of progression or death for patients treated with continuous Rd compared with those treated with MPT (HR 0.72; 95% CI, 0.61 to 0.85; P<0.001) and a 30% reduction compared with Rd18 (HR 0.70; 95% CI, 0.60 to 0.82; P<0.001) in the study.
The pre-planned interim analysis of overall survival demonstrated a 22% reduction in risk of death for continuous Rd vs. MPT (HR 0.78; 95% CI, 0.64 to 0.96; P=0.02), although the difference did not cross the pre-specified superiority boundary (P<0.0096). As of the time of the analysis (May 24, 2013), 121 of 535 (23%) patients in the continuous Rd arm were still on therapy.
Additional secondary endpoints showed response rates were also significantly better with continuous Rd (75%) and with Rd18 (73%) than with MPT (62%; P<0.001 for both comparisons). More patients achieved a very good partial response or better in the continuous Rd (44%) or Rd18 arms (43%) compared with MPT (28%). Complete response rates were 15%, 14% and 9% for continuous Rd, Rd18 and MPT, respectively. Median duration of response was 35.0 months with continuous Rd compared with 22.3 months for MPT (HR 0.63; P<0.001) and 22.1 months for Rd18 (HR 0.60; P<0.001). Median time to disease progression was 32.5 months for patients receiving continuous Rd compared with 23.9 months (HR 0.68; P<0.001) for MPT and 21.9 months (HR 0.62; P<0.001) for Rd18.
Safety results showed that grade 3/4 adverse events that occurred in at least 8% of patients in the continuous Rd arm, Rd18 arm or MPT arm included neutropenia (28%, 26%, 45%, respectively), anemia (18%, 16%, 19%), thrombocytopenia (8%, 8%,11%), febrile neutropenia (1%, 3%, 3%), leukopenia (5%, 6%, 10%), infection (29%, 22%, 17%), pneumonia (8%, 8%, 6%), deep-vein thrombosis and/or pulmonary embolism (8%, 6%, 5%), asthenia (8%, 6%, 6%), fatigue (7%, 9%, 6%), and peripheral sensory neuropathy (1%, <1%, 9%). Rates of grade 3/4 cardiac disorders for patients in the continuous Rd, Rd18 and MPT arms were 12%, 7% and 9%, respectively. The incidence of invasive second primary malignancies was 3% in patients taking continuous Rd, 6% in patients taking Rd18 and 5% in those taking MPT; the overall incidence of solid tumors was identical in the continuous Rd and MPT arms (3%) and 5% in the Rd18 arm.

Based on the results of the FIRST study, Celgene submitted REVLIMID in combination with dexamethasone for the treatment of newly diagnosed multiple myeloma patients with the European Medicines Agency (EMA) in February 2014 and with the U.S. Food and Drug Administration (FDA) in April 2014.
These results are from an investigational study. REVLIMID is not indicated for use in newly diagnosed multiple myeloma patients in any country.
About FIRST ™
In the FIRST (Frontline Investigation of REVLIMID + Dexamethasone Versus Standard Thalidomide) trial, 1,623 patients from 18 countries either ≥65 or <65 years of age and ineligible for stem cell transplant were randomized 1:1:1 into three arms: REVLIMID plus low-dose dexamethasone in 28-day cycles until disease progression (continuous Rd); REVLIMID plus low-dose dexamethasone for 72 weeks (18 cycles, Rd18); or melphalan, prednisone and thalidomide in 42-day cycles for 72 weeks (12 cycles, MPT). The primary endpoint was a comparison of progression-free survival for continuous Rd versus MPT.

Important Safety Information
WARNING: EMBRYO-FETAL TOXICITY, HEMATOLOGIC TOXICITY, and VENOUS THROMBOEMBOLISM
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 embryo-fetal death. In females of reproductive potential, obtain 2 negative pregnancy tests before starting REVLIMID treatment. Females of reproductive potential must use 2 forms of contraception or continuously abstain from heterosexual sex during and for 4 weeks after REVLIMID treatment. To avoid embryo-fetal exposure to lenalidomide, REVLIMID is only available through a restricted distribution program, the REVLIMID REMS ™ program (formerly known as the “RevAssist ® ”program).

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.
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 thromboembolism. The decision to take prophylactic measures should be done carefully after an assessment of an individual patient’s underlying risk factors.
- REVLIMID can cause fetal harm when administered to a pregnant female.
Lenalidomide is contraindicated in females who are pregnant. If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus
- REVLIMID is contraindicated in patients who have demonstrated hypersensitivity (e.g., angioedema, Stevens-Johnson syndrome, toxic epidermal necrolysis) to lenalidomide
WARNINGS AND PRECAUTIONS
- REVLIMID is an analogue of thalidomide, a known human teratogen that causes life-threatening human birth defects or embryo-fetal death. An embryo-fetal development study in monkeys indicates that lenalidomide produced malformations in the offspring of female monkeys who received the drug during pregnancy, similar to birth defects observed in humans following exposure to thalidomide during pregnancy
- Females of Reproductive Potential: Must avoid pregnancy for at least 4 weeks before beginning REVLIMID therapy, during therapy, during dose interruptions and for at least 4 weeks after completing therapy. Must commit either to abstain continuously from heterosexual sexual intercourse or to use two methods of reliable birth control beginning 4 weeks prior to initiating treatment with REVLIMID, during therapy, during dose interruptions and continuing for 4 weeks following discontinuation of REVLIMID therapy. Must obtain 2 negative pregnancy tests prior to initiating therapy
- Males: Lenalidomide is present in the semen of patients receiving the drug. Males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking REVLIMID and for up to 28 days after discontinuing REVLIMID, even if they have undergone a successful vasectomy. Male patients taking REVLIMID must not donate sperm
- Blood Donation: Patients must not donate blood during treatment with REVLIMID and for 1 month following discontinuation of the drug because the blood might be given to a pregnant female patient whose fetus must not be exposed to REVLIMID
REVLIMID REMS ® Program
Because of embryo-fetal risk, REVLIMID is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) the REVLIMID REMS Program (formerly known as the “RevAssist” Program). Prescribers and pharmacies must be certified with the program and patients must sign an agreement form and comply with the requirements. Further information about the REVLIMID REMS program is available at www.celgeneriskmanagement.com : cts.businesswire.com/ct/CT?id=smartlink&url=http%3A%2F%2Fwww ..

Hematologic Toxicity: REVLIMID can cause significant neutropenia and thrombocytopenia. MM: Patients taking REVLIMID for MM should have their complete blood counts monitored every 2 weeks for the first 12 weeks and then monthly thereafter. In the pooled MM trials Grade 3 and 4 hematologic toxicities were more frequent in patients treated with the combination of REVLIMID and dexamethasone than in patients treated with dexamethasone alone. MCL.
Patients taking REVLIMID for MCL should have their complete blood counts monitored weekly for the first cycle (28 days), every 2 weeks during cycles 2-4, and then monthly thereafter. In the MCL trial, Grade 3 or 4 neutropenia was reported in 43% of the patients. Grade 3 or 4 thrombocytopenia was reported in 28% of the patients. Patients may require dose interruption and/or dose reduction
Venous Thromboembolism: Venous thromboembolic events (predominantly deep venous thrombosis and pulmonary embolism) have occurred in patients with MM treated with lenalidomide combination therapy and patients with MDS or MCL treated with lenalidomide monotherapy. It is not known whether prophylactic anticoagulation or antiplatelet therapy prescribed in conjunction with REVLIMID may lessen the potential for venous thromboembolism
Increased Mortality in Patients With CLL: In a clinical trial in the first line treatment of patients with CLL, single agent REVLIMID therapy increased the risk of death as compared to single agent chlorambucil. In an interim analysis, there were 34 deaths among 210 patients on the REVLIMID treatment arm compared to 18 deaths among 211 patients in the chlorambucil treatment arm, and hazard ratio for overall survival was 1.92 [95% CI: 1.08-3.41] consistent with a 92% increase in risk of death. Serious adverse cardiovascular reactions, including atrial fibrillation, myocardial infarction, and cardiac failure occurred more frequently in the REVLIMID treatment arm. REVLIMID is not indicated and not recommended for use in CLL outside of controlled clinical trials
Second Primary Malignancies: Patients with MM treated with lenalidomide in studies including melphalan and stem cell transplantation had a higher incidence of second primary malignancies, particularly acute myelogenous leukemia (AML) and Hodgkin lymphoma, compared to patients in the control arms who received similar therapy but did not receive lenalidomide. Monitor patients for the development of second malignancies. Take into account both the potential benefit of lenalidomide and the risk of second primary malignancies when considering treatment with lenalidomide
Hepatotoxicity: Hepatic failure, including fatal cases, has occurred in patients treated with lenalidomide in combination with dexamethasone. The mechanism of drug-induced hepatotoxicity is unknown.
Pre-existing viral liver disease, elevated baseline liver enzymes, and concomitant medications may be risk factors. Monitor liver enzymes periodically. Stop REVLIMID upon elevation of liver enzymes. After return to baseline values, treatment at a lower dose may be considered
Allergic Reactions: Angioedema and serious dermatologic reactions including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported. These events can be fatal. Patients with a prior history of Grade 4 rash associated with thalidomide treatment should not receive REVLIMID. REVLIMID interruption or discontinuation should be considered for Grade 2-3 skin rash. REVLIMID must be discontinued for angioedema, Grade 4 rash, exfoliative or bullous rash, or if SJS or TEN is suspected and should not be resumed following discontinuation for these reactions. REVLIMID capsules contain lactose.
Risk-benefit of REVLIMID treatment should be evaluated in patients with lactose intolerance
Tumor Lysis Syndrome: Fatal instances of tumor lysis syndrome (TLS) have been reported during treatment with lenalidomide. The patients at risk of TLS are those with high tumor burden prior to treatment. These patients should be monitored closely and appropriate precautions taken
Tumor Flare Reaction: Tumor flare reaction (TFR) has occurred during investigational use of lenalidomide for CLL and lymphoma, and is characterized by tender lymph node swelling, low grade fever, pain and rash. REVLIMID is not indicated and not recommended for use in CLL outside of controlled clinical trials
Monitoring and evaluation for TFR is recommended in patients with MCL.
Tumor flare may mimic the progression of disease (PD). In patients with Grade 3 or 4 TFR, it is recommended to withhold treatment with lenalidomide until TFR resolves to ≤ Grade 1. In the MCL trial, approximately 10% of subjects experienced TFR; all reports were Grade 1 or 2 in severity. All of the events occurred in cycle 1 and one patient developed TFR again in cycle 11. Lenalidomide may be continued in patients with Grade 1 and 2 TFR without interruption or modification, at the physician’s discretion. Patients with Grade 1 or 2 TFR may also be treated with corticosteroids, non-steroidal anti-inflammatory drugs (NSAIDs) and/or narcotic analgesics for management of TFR symptoms.
Patients with Grade 3 or 4 TFR may be treated for management of symptoms per the guidance for treatment of Grade 1 and 2 TFR

Periodic monitoring of digoxin plasma levels, in accordance with clinical judgment and based on standard clinical practice in patients receiving this medication, is recommended during administration of REVLIMID. It is not known whether there is an interaction between dexamethasone and warfarin. Close monitoring of PT and INR is recommended in MM patients taking concomitant warfarin. Erythropoietic agents, or other agents, that may increase the risk of thrombosis, such as estrogen containing therapies, should be used with caution in MM patients receiving lenalidomide with dexamethasone
USE IN SPECIFIC POPULATIONS
Pregnancy: If pregnancy does occur during treatment, immediately discontinue the drug. Under these conditions, refer patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Any suspected fetal exposure to REVLIMID must be reported to the FDA via the MedWatch program at 1-800-332-1088 and also to Celgene Corporation at 1-888-423-5436
Nursing Mothers: It is not known whether REVLIMID is excreted in human milk. Because many drugs are excreted in human milk and because of the potential for adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or the drug, taking into account the importance of the drug to the mother
Pediatric Use: Safety and effectiveness in pediatric patients below the age of 18 have not been established
Geriatric Use: Since elderly patients are more likely to have decreased renal function, care should be taken in dose selection.
Monitor renal function
Renal Impairment: Since REVLIMID is primarily excreted unchanged by the kidney, adjustments to the starting dose of REVLIMID are recommended to provide appropriate drug exposure in patients with moderate (CLcr 30-60 mL/min) or severe renal impairment (CLcr < 30 mL/min) and in patients on dialysis
