• Any concurrent chemotherapy, investigational product (IP), biologic, or hormonal therapy for cancer treatment. Concurrent use of hormonal therapy for non-cancer-related conditions (e.g., hormone replacement therapy) is acceptable. However, the palliative radiation to non-targeted lesions is allowed

• Abdominal fistula, GI perforation, bowel obstruction, or intra-abdominal abscess within 8 weeks before first dose. Note: Complete healing of an intra-abdominal abscess must be confirmed before first dose

• Major surgery (e.g., GI surgery, removal or biopsy of brain metastasis) within 8 weeks before first dose of study treatment. Complete wound healing from major surgery must have occurred 1 month before first dose and from minor surgery (e.g., simple excision, tooth extraction) at least 10 days before first dose. Patients with clinically relevant ongoing complications from prior surgery are not eligible

• History of organ transplantation

• Mean QT interval corrected for heart rate (QTcF) >470 ms calculated from 3 electrocardiograms (ECGs) (within 15 minutes at 5 minutes apart) using Fridericia's Correction

• Participants must remain on antiviral therapy for the study duration and for 6 months after the last dose of study treatment. Participants who test positive for anti-HBc with undetectable HBV DNA (<10 IU/mL or under the limit of detection per local laboratory) do not require antiviral therapy unless HBV DNA exceeds 10IU/mL or reaches detectable limits per local laboratory during the course of treatment

• Patients positive for hepatitis C (HCV) antibody. EXCEPTIONS: Patients positive for hepatitis C (HCV) are eligible only if polymerase chain reaction is negative for HCV RNA.
