Participants with basal cell carcinoma of skin, squamous cell carcinoma of skin, or carcinoma in situ (eg, breast carcinoma, cervical cancer in situ) that have undergone potential curative therapy are not excluded. Participants with low-risk, early-stage prostate cancer (T1-T2a, Gleason score =6, and prostate-specific antigen <10 ng/mL) either treated with definitive intent or untreated in active surveillance with stable disease (SD) are not excluded, Has active central nervous system (CNS) disease, Has an active infection requiring systemic therapy, Has received prior systemic anti-cancer therapy within 4 weeks prior to allocation, Is currently participating in or has participated in a study of an investigational agent or has used an investigational device within 4 weeks prior to the first dose of study intervention, Has any clinically significant gastrointestinal abnormalities that might alter absorption, History of severe bleeding disorders
