Bottom Line. At EHA26, bexobrutideg and comp tacabrutideg show broadly comparable efficacy

across both relapsed/ refractory and BTKi-naïve settings (ORR ~83-85% in R/R and ~84-86% in

earlier line), reinforcing the emerging BTK degrader class as a credible next-generation backbone.

While nuances exist around follow-up duration and reporting, these differences are not yet

meaningful enough to establish clear clinical separation. Overall, the data suggest both agents are

competitive and potentially superior to current BTKi, with no clear leader emerging, and differentiation

likely to depend on longer-term durability, safety with broader exposure, and performance in pivotal and

combo settings.

Core efficacy metrics remain largely unchanged vs the prior ASH25 update. ORR was ~83%

(N=48; unchanged vs ~83% at ASH25) and mPFS was 22.1 mos (unchanged vs ASH25) in heavily

pretreated r/r CLL/ SLL pts (Chart 1).
