Arms

  • Experimental: Arm A: BGB-16673 Monotherapy
    Participants will receive BGB-16673 once daily until any of the treatment discontinuation criteria are met
  • Active Comparator: Arm B: Investigator's Choice
    Participants will receive investigator's choice of bendamustine plus rituximab or high-dose methylprednisolone plus rituximab for up to six 28-day cycles. Participants with unequivocal disease progression confirmed by Independent Review Committee (IRC) may cross over to receive treatment with BGB-16673 at the Investigator's discretion
