Participants will be assigned to receive study treatment until disease recurrence, unacceptable adverse events (AEs), intercurrent illness that prevents further administration of treatment, Investigator’s decision to withdraw the participant, noncompliance with study treatment or procedural requirements, administrative reasons requiring cessation of treatment, or until the participant has received 17 cycles of study treatment (approximately 1 year).
