Celgene Receives Positive CHMP Opinion to Extend REVLIMID® (Lenalidomide) for Continuous Use in Patients with Newly Diagnosed Multiple Myeloma and Ineligible for Transplant

BOUDRY, Switzerland. - Friday, December 19th 2014 [ME NewsWire]

(BUSINESS WIRE) Celgene International Sàrl, a wholly owned subsidiary of Celgene Corporation (NASDAQ: CELG), today announced that the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) has adopted a positive opinion for continuous oral treatment with REVLIMID® in adult patients with previously untreated multiple myeloma who are not eligible for stem cell transplantation.

The CHMP reviews applications for all 28 member states in the European Union (EU), as well as Norway, Liechtenstein and Iceland. The European Commission, which generally follows the recommendation of the CHMP, is expected to make its final decision in approximately two months. If approval is granted, detailed conditions for the use of this product will be described in the Summary of Product Characteristics (SmPC), which will be published in the revised European Public Assessment Report (EPAR).

Multiple myeloma is a persistent and life-threatening blood cancer that is characterised by tumour proliferation and suppression of the immune system. 1 It is a rare but deadly disease: around 38,900 people were newly diagnosed with multiple myeloma in Europe in 2012, and 24,300 people died from the disease in the same year. 2 On average, multiple myeloma is diagnosed between 65-74 years of age. 3 The majority of newly diagnosed patients are not eligible for more aggressive treatment options such as high-dose chemotherapy with stem cell transplant,4 and there is currently no therapy option approved for continuous treatment to help manage the disease over the long term. 5

“When recommending a therapy at first diagnosis, our aim is to keep the disease under control for as long as possible,” says Professor Thierry Facon, Services des Maladies du Sang, Hôpital Claude Huriez, and CHRU Lille, France. “The positive opinion for REVLIMID for the continuous treatment of adult patients with previously untreated multiple myeloma who are not eligible for transplant is a significant step towards bringing a new therapy that could extend the time patients live without their disease progressing.”

The anticipated European Commission decision would be the latest milestone for Celgene’s flagship product in Europe and its continued focus on delivering innovative medicines for rare haematological diseases. REVLIMID is already indicated in combination with dexamethasone for the treatment of multiple myeloma in adult patients who have received at least one prior therapy. REVLIMID is also indicated for the treatment of patients with transfusion-dependent anaemia due to low- or intermediate-1-risk myelodysplastic syndromes (MDS) associated with an isolated deletion 5q cytogenetic abnormality when other therapeutic options are insufficient or inadequate.

Tuomo Pätsi, President of Celgene in Europe, the Middle East and Africa (EMEA), said, “The CHMP opinion reflects the important role that therapies like REVLIMID play in treating rare haematological cancers including multiple myeloma. Innovative medicines have been critical in helping to improve patient outcomes, but despite tremendous progress over the last 10 years, myeloma remains incurable for the vast majority of patients, so new treatments are needed. At Celgene, we will continue to invest more than one-third of our revenues back into research and development to continue finding new treatment options for these patients. Our hope is that one day, deadly diseases like multiple myeloma could become a manageable, long-term chronic condition.”

The CHMP recommendation in newly diagnosed multiple myeloma was based on the results of two pivotal studies: MM-015 and MM-020 (also known as FIRST). The results of these studies have been reported previously.

    The FIRST study, MM-020,6 was the largest phase III, randomised study of 1,623 patients newly diagnosed with multiple myeloma and not eligible for stem cell transplantation. It compared lenalidomide–dexamethasone (Rd) administered in 28-day cycles until disease progression, with Rd for 72 weeks (18 cycles), and melphalan–prednisone–thalidomide (MPT) for 72 weeks.
    MM-0157 was a phase III study of 459 patients that compared melphalan–prednisone–lenalidomide induction followed by lenalidomide maintenance (MPR-R) with melphalan–prednisone–lenalidomide (MPR) or melphalan–prednisone (MP) followed by placebo in patients ≥65 years or older with newly diagnosed multiple myeloma.

REVLIMID is not currently indicated for the treatment of newly diagnosed multiple myeloma in any country.

Important Safety Information


WARNING: EMBRYO-FETAL TOXICITY, HEMATOLOGIC TOXICITY, and VENOUS and ARTERIAL THROMBOEMBOLISM

EMBRYO-FETAL TOXICITY

    Lenalidomide, a thalidomide analogue, caused limb abnormalities in a developmental monkey study similar to birth defects caused by thalidomide in humans. If lenalidomide is used during pregnancy, it may cause birth defects or embryo-fetal death.
    Pregnancy must be excluded before start of treatment. Prevent pregnancy during treatment by the use of two reliable methods of contraception.

REVLIMID is available only through a restricted distribution program called the REVLIMID REMS™ program (formerly known as the “RevAssist® program”).

HEMATOLOGIC TOXICITY.

REVLIMID can cause significant neutropenia and thrombocytopenia.

    For patients with del 5q myelodysplastic syndromes, monitor complete blood counts weekly for the first 8 weeks and monthly thereafter.

VENOUS AND ARTERIAL THROMBOEMBOLISM

    Significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as risk of myocardial infarction and stroke in patients with multiple myeloma receiving REVLIMID with dexamethasone. Anti-thrombotic prophylaxis is recommended.

CONTRAINDICATIONS

Pregnancy:

    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

Allergic Reactions:

    REVLIMID is contraindicated in patients who have demonstrated hypersensitivity (e.g., angioedema, Stevens-Johnson syndrome, toxic epidermal necrolysis) to lenalidomide

WARNINGS AND PRECAUTIONS

Embryo-Fetal Toxicity:

    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 or by telephone at 1-888-423-5436.

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

DRUG INTERACTIONS

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
