- Histologically and/or cytologically confirmed solid tumor malignancy
- Safety lead in- Advanced non-central nervous system (CNS) primary tumors that have progressed after first line treatment, who are intolerant to first line treatment, or who are unable to receive first line treatment, and for whom pembrolizumab, or pembrolizumab-based therapy is considered appropriate
- Expansion 1- Patients with a confirmed diagnosis of advanced gastric or gastroesophageal junction (GEJ) tumors that have progressed after first line treatment, who are intolerant to first line treatment, or who are unable to receive first line treatment
- Expansion 2- Patients with a confirmed diagnosis of advanced bladder/urothelial tumors that have progressed after first line treatment, or who are intolerant to first line treatment, or who are unable to receive first line treatment with cisplatin-based chemotherapy.
- Expansion 3- Confirmed diagnosis of advanced non-small cell lung cancer (NSCLC) previously treated with anti-PD-1 or anti-PD-L1 therapy.
- Adequate organ function
- Creatinine clearance \> 30 mL/min
- Total serum bilirubin \< 1.5 × upper limit of normal (ULN) unless due to Gilbert's syndrome, tumor involvement, hemolysis or considered an effect of regular blood transfusions

- Lesions that have had external beam radiotherapy or loco-regional therapies such as radiofrequency ablation must show subsequent evidence of substantial size increase (ex. 20% increase in LD) to be deemed a target lesion.
- Negative serum or urine pregnancy test prior to study treatment initiation in female subjects of childbearing potential.

- Current (non-infectious) pneumonitis, or a history of pneumonitis that required steroids.
- A live vaccine administered within 30 days of the first dose of study treatment.
- Receipt of any investigational product within 14 days or 5 half-lives prior to study treatment initiation, whichever is shortest.
