BeiGene announced positive results from a planned interim analysis of the Phase 3 ALPINE trial comparing BRUKINSA® (zanubrutinib) against ibrutinib in adults with relapsed or refractory (R/R) chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). The results will be presented as a late-breaking abstract at the EHA 2021 Presidential Symposium by Prof. Peter Hillmen (United Kingdom) p204-6 (LB1900).
BRUKINSA met the primary endpoint of the trial, demonstrating non-inferiority in objective response rate (ORR) by both investigator and independent review committee (IRC) assessments (p < 0.0001). The trial also demonstrated superior ORR with a statistically significant improvement in ORR for BRUKINSA vs. ibrutinib (p = 0.0006) by investigator assessment, as well as a numerically higher ORR but not statistically significant improvement by IRC (p = 0.0121 compared to the two-sided stringent statistical boundary of p < 0.0099 set for the interim analysis). The interim analysis from this fully-enrolled, ongoing trial is based on 415 of 652 patients followed for a minimum of 12 months.
