SUMMIT, N.J.--(BUSINESS WIRE)--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, recommending the approval of REVLIMID (lenalidomide) in combination with rituximab (anti-CD20 antibody) (R) for the treatment of adult patients with previously treated follicular lymphoma (FL) (Grade 1-3a). If approved by the European Commission (EC), R2 will be the first combination treatment regimen for patients with FL that does not include chemotherapy.

Since its initial approval in 2007, REVLIMID has continued to demonstrate its benefits across a range of serious blood disorders in Europe and a CHMP positive opinion for this combination with rituximab is very good news for patients with follicular lymphoma. We look forward to the European Commission decision, said Tuomo Ptsi, President of Hematology/Oncology for Celgene Worldwide Markets.

In FL, a subtype of indolent NHL, the immune system is not functioning optimally.1,2 When this dysfunction occurs, the immune system either fails to detect or attack cancerous cells.1,2 Rituximab is a monoclonal antibody that targets the CD 20 antigen on the surface of pre-B and mature B-lymphocytes. Upon binding to CD20, rituximab causes B-cell lysis. Lenalidomide is an immunomodulator that increases the number and activation of T and natural killer (NK) cells, resulting in the lysis of tumor cells. The R2 combination regimen acts by complementary mechanisms to help the patients immune system to find and destroy the cancer cells.3

Given the incurable nature of FL2, a high unmet medical need exists for the development of novel treatment options with new mechanisms of action and a tolerable safety profile to help improve progression-free survival (PFS) especially in the setting of previously treated FL.

The estimated incidence of NHL in Europe was 100,055 cases in 2018; FL accounts for approximately 25% of all NHL cases and is the most common form of indolent NHL.3,4,5

Chemotherapy is a standard of care for indolent forms of NHL, but most patients will relapse or become refractory to their current treatment, said Prof. John Gribben, President of EHA and Centre for Haemato-Oncology, Barts Cancer Institute, in England The combination of REVLIMID and rituximab could represent a new, chemotherapy-free treatment option for patients with previously treated follicular lymphoma.

The CHMP positive opinion is based primarily on results from the randomized, multi-center, double-blind, Phase 3 AUGMENT study, which evaluated the efficacy and safety of the R combination versus rituximab plus placebo in patients with previously treated FL (n=295).6,7 Additionally, findings from the MAGNIFY study were included as support for the safety and the efficacy of lenalidomide plus rituximab in patients with relapsed or refractory FL, including rituximab refractory FL patients.8

The CHMP reviews applications for all member states of 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 REVLIMID Summary of Product Characteristics (SmPC), which will be published in the revised European Public Assessment Report (EPAR).

About Follicular Lymphoma

Lymphoma is a blood cancer that develops in lymphocytes, a type of white blood cell in the immune system that helps protect the body from infection.9 There are two classes of lymphoma Hodgkins lymphoma and non-Hodgkins lymphoma (NHL) each with specific subtypes that determine how the cancer behaves, spreads and should be treated.3,10,11 Other differentiating factors of lymphomas are what type of lymphocyte is affected (T cell or B cell) and how mature the cells are when they become cancerous.11

Follicular lymphoma is the most common indolent (slow-growing) form of NHL, accounting for approximately 25% of all Non-Hodgkin lymphoma (NHL) patients.5,12 Most patients present with advanced disease usually when lymphoma-related symptoms appear (e.g., nodal disease, B symptoms, cytopenia) and receive systemic chemoimmunotherapy.5 While follicular lymphoma patients are generally responsive to initial treatment, the disease course is characterized by recurrent relapses over time with shorter remission periods.13

About AUGMENT

AUGMENT is a Phase 3, randomized, double-blind clinical trial evaluating the efficacy and safety of REVLIMID (lenalidomide) in combination with rituximab (R) versus rituximab plus placebo in patients with previously treated follicular lymphoma (FL). AUGMENT included patients diagnosed with Grade 1, 2 or 3a FL, who were previously treated with at least 1 prior systemic therapy and two previous doses of rituximab. Patients were documented relapsed, refractory or progressive disease following systemic therapy, but were not rituximab-refractory.6,7

The primary endpoint was progression-free survival, defined as the time from date of randomization to the first observation of disease progression or death due to any cause. Secondary and exploratory endpoints included overall response rate, durable complete response rate, complete response rate, duration of response, duration of complete response, overall survival, event-free survival and time to next anti-lymphoma therapy.6,7

About REVLIMID

REVLIMID is approved in Europe and the United States as monotherapy, indicated for the maintenance treatment of adult patients with newly diagnosed multiple myeloma (MM) who have undergone autologous stem cell transplantation. REVLIMID as combination therapy is approved in Europe, in the United States, in Japan and in around 25 other countries for the treatment of adult patients with previously untreated MM who are not eligible for transplant. REVLIMID is also approved in combination with dexamethasone for the treatment of patients with MM 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 myelodysplastic syndromes (MDS) associated with a deletion 5q cytogenetic abnormality with or without additional cytogenetic abnormalities and in Europe for the treatment of patients with transfusion-dependent anemia due to low- or intermediate-1-risk MDS associated with an isolated deletion 5q cytogenetic abnormality when other therapeutic options are insufficient or inadequate.

In addition, REVLIMID is approved in Europe for the treatment of patients with mantle cell lymphoma (MCL) and in the United States for the treatment of patients with MCL whose disease has relapsed or progressed after two prior therapies, one of which included bortezomib. In Switzerland, REVLIMID is indicated for the treatment of patients with relapsed or refractory MCL after prior therapy that included bortezomib and chemotherapy/rituximab.

REVLIMID is not indicated and is not recommended for the treatment of patients with chronic lymphocytic leukemia (CLL) outside of controlled clinical trials.

Important Safety Information

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

Embryo-Fetal Toxicity

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.

Information about the REVLIMID REMS program is available at http://www.celgeneriskmanagement.com or by calling the manufacturers 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.

Venous and Arterial Thromboembolism

REVLIMID has demonstrated a significantly increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE), as well as risk of myocardial infarction and stroke in patients with MM who were treated with REVLIMID and dexamethasone therapy. Monitor for and advise patients about signs and symptoms of thromboembolism. Advise patients to seek immediate medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. Thromboprophylaxis is recommended and the choice of regimen should be based on an assessment of the patients underlying risks.

CONTRAINDICATIONS

Pregnancy: REVLIMID can cause fetal harm when administered to a pregnant female and 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 risk to the fetus

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

WARNINGS AND PRECAUTIONS

Embryo-Fetal Toxicity: See Boxed WARNINGS

REVLIMID REMS Program: See Boxed WARNINGS: Prescribers and pharmacies must be certified with the REVLIMID REMS program by enrolling and complying with the REMS requirements; pharmacies must only dispense to patients who are authorized to receive REVLIMID. Patients must sign a Patient-Physician Agreement Form and comply with REMS requirements; female patients of reproductive potential who are not pregnant must comply with the pregnancy testing and contraception requirements and males must comply with contraception requirements

Hematologic Toxicity: REVLIMID can cause significant neutropenia and thrombocytopenia. Monitor patients with neutropenia for signs of infection. Advise patients to observe for bleeding or bruising, especially with use of concomitant medications that may increase risk of bleeding. MM: Patients taking REVLIMID/dex or REVLIMID as maintenance therapy should have their complete blood counts (CBC) assessed every 7 days for the first 2 cycles, on days 1 and 15 of cycle 3, and every 28 days thereafter. MDS: 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 dose reduction. Please see the Black Box WARNINGS for further information. MCL: Patients taking REVLIMID for MCL should have their CBCs monitored weekly for the first cycle (28 days), every 2 weeks during cycles 2-4, and then monthly thereafter. Patients may require dose interruption and/or dose reduction

Venous and Arterial Thromboembolism: See Boxed WARNINGS: Venous thromboembolic events (DVT and PE) and arterial thromboses (MI and CVA) are increased in patients treated with REVLIMID. Patients with known risk factors, including prior thrombosis, may be at greater risk and actions should be taken to try to minimize all modifiable factors (e.g., hyperlipidemia, hypertension, smoking). Thromboprophylaxis is recommended and the regimen should be based on patients underlying risks. ESAs and estrogens may further increase the risk of thrombosis and their use should be based on a benefit-risk decision

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. Serious adverse cardiovascular reactions, including atrial fibrillation, myocardial infarction, and cardiac failure, occurred more frequently in the REVLIMID arm. REVLIMID is not indicated and not recommended for use in CLL outside of controlled clinical trials

Second Primary Malignancies (SPM): In clinical trials in patients with MM receiving REVLIMID, an increase of hematologic plus solid tumor SPM, notably AML and MDS, have been observed. Monitor patients for the development of SPM. Take into account both the potential benefit of REVLIMID and risk of SPM when considering treatment

Increased Mortality with Pembrolizumab: In clinical trials in patients with multiple myeloma, the addition of pembrolizumab to a thalidomide analogue plus dexamethasone resulted in increased mortality. Treatment of patients with multiple myeloma with a PD-1 or PD-L1 blocking antibody in combination with a thalidomide analogue plus dexamethasone is not recommended outside of controlled clinical trials

Hepatotoxicity: Hepatic failure, including fatal cases, has occurred in patients treated with REVLIMID/dex. 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

Severe Cutaneous Reactions: Severe cutaneous reactions including Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) 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. Consider REVLIMID interruption or discontinuation for Grade 2-3 skin rash. Permanently discontinue REVLIMID for Grade 4 rash, exfoliative or bullous rash, or for other severe cutaneous reactions such as SJS, TEN, or DRESS.

Tumor Lysis Syndrome (TLS): Fatal instances of 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 (TFR): TFR has occurred during investigational use of lenalidomide for CLL and lymphoma. 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 REVLIMID until TFR resolves to Grade 1. REVLIMID may be continued in patients with Grade 1 and 2 TFR without interruption or modification, at the physicians discretion

Impaired Stem Cell Mobilization: A decrease in the number of CD34+ cells collected after treatment (>4 cycles) with REVLIMID has been reported. Consider early referral to transplant center to optimize timing of the stem cell collection

Thyroid Disorders: Both hypothyroidism and hyperthyroidism have been reported. Measure thyroid function before start of REVLIMID treatment and during therapy

Early Mortality in Patients with MCL: In another MCL study, there was an increase in early deaths (within 20 weeks), 12.9% in the REVLIMID arm versus 7.1% in the control arm. Risk factors for early deaths include high tumor burden, MIPI score at diagnosis, and high WBC at baseline (10 x 109/L)

Hypersensitivity: Hypersensitivity, including angioedema, anaphylaxis, and anaphylactic reactions to REVLIMID has been reported. Permanently discontinue REVLIMID for angioedema and anaphylaxis.

ADVERSE REACTIONS

Multiple Myeloma

Myelodysplastic Syndromes

Mantle Cell Lymphoma

DRUG INTERACTIONS

Periodic monitoring of digoxin plasma levels is recommended due to increased Cmax and AUC with concomitant REVLIMID therapy. Patients taking concomitant therapies such as erythropoietin stimulating agents or estrogen containing therapies may have an increased risk of thrombosis. It is not known whether there is an interaction between dex and warfarin. Close monitoring of PT and INR is recommended in patients with MM taking concomitant warfarin
