BGB-16673

Instead of blocking BTK, this pill destroys it, so it works even when the enzyme has mutated to escape every inhibitor.

Chimeric degradation-activating compound recruiting an E3 ligase to BTK. CaDAnCe-101 (phase 1, relapsed CLL/SLL after covalent BTKi, many with BTK mutations): ORR 86% in 66 patients with a manageable profile (fatigue, bruising, diarrhoea, neutropenia), updated at EHA 2026. Phase 3 CaDAnCe-304 (~500 patients) compares BGB-16673 with pirtobrutinib after covalent BTKi. The first BTK degrader in phase 3.

1.BGB-16673 bridges BTK and an E3 ubiquitin ligase

Modality
Small-molecule BTK degrader (CDAC)
Mechanism
Heterobifunctional degrader: one end binds BTK (wild-type or C481/T474/L528 mutant), the other recruits an E3 ligase, tagging BTK for proteasomal destruction.
Dosing & schedule
Route
Oral
Schedule
