BeiGene’s Brukinsa OK’d for Marginal Zone Lymphoma
FDA has granted accelerated approval for BeiGene’s Brukinsa (zanubrutinib) for treating adult patients with relapsed or refractory marginal zone lymphoma who have received at least one anti-CD20-based regimen. Approval is based on efficacy data from two single-arm clinical trials, with overall response rate (ORR) as the primary endpoint, according to the company.
In the Phase 2 MAGNOLIA trial (NCT03846427), 66 patients were evaluated. Based on assessment using CT scanning, the ORR was 56% with a complete response (CR) rate of 20%. In the Phase 1/2 trial BGB-3111-AU-003 (NCT02343120), a total of 20 patients were assessed. Based on an assessment using CT scanning, the ORR was 80% with a CR rate of 20%.
BeiGene says Brukinsa is a small molecule inhibitor of Bruton’s tyrosine kinase that is currently being evaluated globally for treating B-cell malignancies, according to the company. It was approved 11/2019 for mantle cell lymphoma in adult patients who have received at least one prior therapy.
