Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Nemtabrutinib
Treatment: Drugs - Venetoclax
Treatment: Other - Rituximab

Experimental: Nemtabrutinib + Venetoclax - Participants will receive nemtrabrutinib oral tablets at specified doses daily starting at Cycle 1 Day 1 (C1D1) and venetoclax oral tablets at doses of 20 mg up to 400 mg daily starting at Cycle 2 Day 1 (C2D1) up to 2 years post C2D1 or until progressive disease (PD) or discontinuation. A cycle = 4 weeks.

Active comparator: Venetoclax + Rituximab - Participants will receive venetoclax oral tablets at doses from 20 mg up to 400 mg daily starting at C1D1 on 4-week cycles up to 2 years and rituximab or biosimilar at 375 mg/m\^2 up to 500 mg/m2 intravenous infusion once per 28-day cycle starting at C2D1, for 6 total cycles. Treatment will continue until progressive disease (PD) or discontinuation.
