Arms of the Study
Arm 1
Experimental
Venetoclax
Venetoclax will be administered orally once daily (QD) beginning with a dose-titration phase. The initial venetoclax dose is 20 mg QD. After 1 week of treatment at 20 mg QD, the dose will be escalated to 50 mg QD followed by subsequent increases, each after 1 week, to 100 mg QD, 200 mg QD and the maximum dose of 400 mg QD. Participants may continue to receive venetoclax for up to 2 years provided they continue to tolerate the drug, have no evidence of disease progression (based on investigator's assessment), do not have unacceptable toxicity, and do not meet any of the criteria for discontinuation. In countries where venetoclax is not commercially available, participants who continue to derive benefit after 2 years of treatment may be able to extend their treatment for up to 2 additional years, plus one additional year until the venetoclax extension study was open, determined on a case by case basis.
