Celgene Corporation Announces Results of AUGMENT Evaluating REVLIMID® In Combination with Rituximab (R2) In Patients with Relapsed/Refractor

SUMMIT, N.J. -Monday 3 December 2018 [ AETOS Wire ]


Pivotal phase 3 data show investigational R2 significantly extended progression-free survival compared with rituximab plus placebo

Positive trend in overall survival was observed

Regulatory submissions planned for Q1 2019

(BUSINESS WIRE)-- Celgene Corporation (NASDAQ: CELG) today announced results of the phase 3 AUGMENT study, which showed that REVLIMID® (lenalidomide) in combination with rituximab (R2) demonstrated superior progression-free survival (PFS) in patients with relapsed/refractory indolent lymphoma compared to patients who received rituximab plus placebo (R-placebo). The data were presented by John Leonard, M.D. in an oral presentation at the 60th American Society of Hematology (ASH) Annual Meeting and Exposition in San Diego, C.A. (Abstract #445).

The phase 3 randomized, double-blind, international clinical study evaluated the efficacy and safety of the investigational combination of R2 versus rituximab plus placebo in patients (n=358) with relapsed/refractory follicular (n=295) and marginal zone (n=63) lymphoma.

In the study, the R2 arm demonstrated a highly statistically significant improvement in the primary endpoint of progression-free survival (PFS), evaluated by an independent review committee, versus (vs.) the R-placebo arm. The median PFS was 39.4 months for patients treated with R2 and 14.1 months for those treated with R-placebo (P

“The AUGMENT data, with R2 more than doubling progression-free survival over rituximab monotherapy, represents an important potential new treatment option for patients with relapsed/refractory follicular or marginal zone lymphoma,” said John Leonard, M.D., AUGMENT lead investigator, The Richard T. Silver Distinguished Professor of Hematology and Medical Oncology and director of the Joint Clinical Trials Office at Weill Cornell Medicine, who has also served as a consultant for Celgene.

Overall survival (OS), a secondary endpoint, showed a positive trend for improvement in the R2 arm vs. the control arm (16 vs. 26 death events) (HR: 0.61; 95% CI, 0.33-1.13). Two-year OS rate was 93% for patients receiving R2 and 87% for those receiving R-placebo.

Overall response rate (ORR), another secondary endpoint, was 78% (n=138) in the R2 arm vs. 53% (n=96) in the R-placebo arm, according to the independent review committee. Duration of response (DoR) was significantly improved for R2 vs. R-placebo with median DoR of 37 vs. 22 months, respectively (P =0.0015; HR: 0.53; 95% CI, 0.36-0.79).

The most frequent adverse event (AE) in the R2 arm was neutropenia (58%), vs. 22% in the R-placebo arm. Additional commonly observed AEs in more than 20% of patients included diarrhea (31% in the R2 arm vs. 23% in R-placebo), constipation (26% vs. 14%, respectively), cough (23% vs. 17%), and fatigue (22% vs. 18%), respectively. Adverse events that were reported at a higher rate (>10%) in the R2 arm were neutropenia, constipation, leukopenia, anemia, thrombocytopenia and tumor flare. No unexpected safety findings were observed in the AUGMENT trial.

“These data represent a potential new treatment strategy for patients with relapsed/refractory indolent non-Hodgkin’s lymphomas,” said Alise Reicin, M.D., President, Global Clinical Development for Celgene. “We are advancing regulatory submissions in the first quarter of 2019 to bring this important combination to patients as soon as possible.”

REVLIMID® alone or in combination with other agents is not approved for use in follicular lymphoma or marginal zone lymphoma in any geography.

About REVLIMID®

REVLIMID® (lenalidomide) in combination with dexamethasone (dex) is indicated for the treatment of patients with multiple myeloma (MM)

REVLIMID is indicated as maintenance therapy in patients with MM following autologous hematopoietic stem cell transplantation (auto-HSCT)

REVLIMID® 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

REVLIMID® is indicated for the treatment of patients with mantle cell lymphoma (MCL) whose disease has relapsed or progressed after two prior therapies, one of which included bortezomib

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 www.celgeneriskmanagement.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.

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 patient’s underlying risks.
