†The VEN+A regimen is designed to be completed after 12 cycles (twelve 28-day treatment cycles), preceded by a 2-cycle acalabrutinib initiation phase. Acalabrutinib is taken orally 100 mg approximately every 12 hours starting on Cycle 1, Day 1, for a total of 14 cycles or until disease progression or unacceptable toxicity. VENCLEXTA is taken orally 400 mg/day until disease progression, unacceptable toxicity, or for a total of 12 cycles after the 2-cycle acalabrutinib initiation phase, starting with the 5-week VENCLEXTA dose ramp-up schedule.
CLL=chronic lymphocytic leukemia; VEN+A=VENCLEXTA + acalabrutinib.
