Health Canada approval for Brukinsa in relapsed or refractory marginal zone lymphoma.- BeiGene

The Health Canada marketing approval for Brukinsa in R/R MZL is based on efficacy results from two open-label, multicenter, single arm clinical trials. In the MAGNOLIA trial (NCT03846427) (n=68), which included previously treated patients with MZL who had received at least one prior anti-CD20-based therapy, 38% of patients had extranodal MZL, 38% had nodal MZL, 18% had splenic MZL and 6% patients had unknown subtype. In BGB-3111-AU-003 (NCT02343120) (n=20), which included patients with previously treated MZL, 45% had extranodal MZL, 25% had nodal MZL and 30% had splenic MZL. Brukinsa Total Daily Dose was 320 mg daily, given as 160 mg twice daily or 320 mg once daily.

As assessed by Independent Review Committee per 2014 Lugano Classification, Brukinsa achieved an overall response rate (ORR) of 68% (95% CI; 56, 79) in the MAGNOLIA trial and 80% (95% CI; 56, 94) in BGB-311-AU-003. In the MAGNOLIA trial, the median response time was 2.8 months (range: 1.7 to 11.1 months).
