Near-term implementable finding

Comparable outcomes of BTK inhibitors and fixed-duration venetoclax plus rituximab in second-line treatment of chronic lymphocytic leukaemia: a real-world analysis by the Czech CLL study group

Two standard second-line treatments for chronic lymphocytic leukemia work similarly well, though one carries higher infection risk—useful for personalized selection.

This Czech real-world study (n=352) found no significant difference in PFS or OS between BTKi monotherapy and fixed-duration VenR in second-line CLL, the first real-world dataset directly comparing these standard options. BTKi had numerically higher infection-related discontinuations, a clinically useful safety distinction for treatment selection.

Why it surfaced

First real-world head-to-head comparison of BTKi vs VenR in R/R CLL second-line, with n=352. Clinically useful for treatment selection. Retrospective design limits causal inference.
