BeiGene announces acceptance of supplemental NDA in China for REVLIMID for the treatment of lymphoma
BeiGene (BGNE) announced that the China National Medical Products Administration has accepted a supplemental new drug application for #REVLIMID, in combination with rituximab, for the treatment of patients with relapsed or refractory indolent lymphoma.
REVLIMID was first approved in China in 2013 for the treatment of multiple myeloma in combination with dexamethasone, in adult patients who have received at least one prior therapy, and the label for the combination was expanded in 2018 to include adult patients with newly-diagnosed multiple myeloma who are not eligible for transplant.
It is currently marketed in China by BeiGene under an exclusive license from Celgene Logistics Sarl, a Bristol-Myers Squibb (BMY) company.
The sNDA is supported by a clinical, non-clinical, and chemistry, manufacturing and control data package, including the results from the pivotal Phase 3 AUGMENT study sponsored and conducted by Bristol-Myers Squibb.
AUGMENT is a randomized, double-blind, multicenter trial in which a total of 358 patients with relapsed or refractory follicular or marginal zone lymphoma were randomized 1:1 to receive REVLIMID and rituximab or rituximab and placebo.
With a median follow-up of 28.3 months, R2 demonstrated clinically meaningful and statistically significant improvement in progression-free survival, evaluated by an independent review committee, relative to the control arm with a 54% reduction in the risk of progression or death.
The median PFS was 39.4 months for the R2 arm and 14.1 months for the control arm with an improvement by more than 2 years. Overall response rate, a secondary endpoint, was 78% in the R2 arm vs. 53% in the control arm, as assessed by the IRC.
Duration of response was significantly improved for R2 vs. control with median DoR of 37 vs. 22 months, respectively.
The most frequent adverse event in the R2 arm was neutropenia, vs. 22% in the control arm.
Additional commonly observed AEs in more than 20% of patients included diarrhea, constipation, cough, and fatigue. Adverse events that were reported at a higher rate in the R2 arm were neutropenia, constipation, leukopenia, anemia, thrombocytopenia and tumor flare.
