CAMBRIDGE, Mass. & BEIJING & MOSCOW October 20, 2021
The Russia Ministry of Health has approved BeiGene’s Brukinsa (zanubrutinib) to treat patients with relapsed or refractory mantle cell lymphoma (MCL).
Marketing approval for BRUKINSA for the treatment of MCL in Russia is based on results from two single-arm clinical trials. Across both trials, as assessed by independent review committee (IRC) per 2014 Lugano Classification, BRUKINSA achieved an overall response rate (ORR) of 83.7%, defined as the combined rate of complete responses (CRs) and partial responses (PRs).
Of the 118 patients with MCL who received at least one prior therapy and received BRUKINSA treatment, serious adverse reactions occurred in 36 patients (31%), with the most frequent being pneumonia (11%) and bleeding (5%). Eight patients (7%) discontinued treatment due to adverse reactions in the trials, with the most frequent being pneumonia (3.4%), and one patient (0.8%) experienced an adverse reaction that led to dose reduction.
The recommended dose of BRUKINSA is either 160 mg twice daily or 320 mg once daily, taken orally with or without food. The dose may be adjusted for adverse reactions and reduced for patients with severe hepatic impairment and certain drug interactions.
The drug is already approved for MCL treatment in nine countries that include the US, China, UAE, Chile, Brazil, Singapore, Israel, Canada and Australia.
BeiGene and Nanolek entered into an exclusive distribution agreement for Nanolek to commercialize BRUKINSA in the Russian Federation
BRUKINSA is a small molecule inhibitor of Bruton’s tyrosine kinase (BTK) discovered by BeiGene scientists that is currently being evaluated globally in a broad clinical program as a monotherapy and in combination with other therapies to treat various B-cell malignancies. Because new BTK is continuously synthesized, BRUKINSA was specifically designed to deliver complete and sustained inhibition of the BTK protein by optimizing bioavailability, half-life, and selectivity. With differentiated pharmacokinetics compared to other approved BTK inhibitors, BRUKINSA has been demonstrated to inhibit the proliferation of malignant B cells within a number of disease relevant tissues.
