Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The main purpose of the study is to evaluate if adding venetoclax to participants receiving cBTKi for the 1L CLL can achieve deep durable remissions of undetectable measurable residual disease \[uMRD \< or 10\^-4 in peripheral blood (PB)\] by end of combination treatment (EOCT) to allow off-treatment period.

The acronym BRAVE stands for Btki Responders to Achieve deep remission (or off-treatment periods) with VEnetoclax.

Venetoclax Added to cBTKi (Commercially Prescribed)

Participants will receive venetoclax, orally, once daily (QD) with a starting ramp-up dose of 20 milligrams (mg) on Day 1 of Cycle 1 (cycle length= 28 days). The dose will increase weekly; thereafter, treatment will continue with venetoclax at the target dose of 400 mg, QD from Day 1 of Cycle 2 up to Day 28 of Cycle 12.

Participants will continue receiving cBTKi-monotherapy (i.e. ibrutinib or acalabrutinib, or zanubrutinib) as previously prescribed by the investigator according to the prescribing label.
