Sitravatinib monotherapy
Sitravatinib plus Tislelizumab
Anti-PD-1/PD-L1 Antibody Naïve or R/R HCC (Monotherapy)
Anti-PD-1/PD-L1 antibody naive HCC(Combination)
Anti-PD-1/PD-L1 antibody refractory/resistant HCC
Anti-PD-1/PD-L1 antibody naive G/GEJ cancer
Two dose levels of sitravatinib as monotherapy, 80 mg once daily and 120 mg once daily, will be evaluated in participants with unresectable locally advanced or metastatic HCC or G/GEJ cancer. A modified 3+3 design will be used in the dose escalation to confirm recommended Phase 2 dose (RP2D)
The combination dose escalation of sitravatinib (80 mg once daily and 120 mg once daily; modified 3+3 design) with tislelizumab (200 mg every 3 weeks, in both cohorts) will be evaluated in unresectable locally advanced or metastatic HCC or G/GEJ cancer participants . If the combination dose of 80 mg sitravatinib and 200 mg tislelizumab has been declared tolerable, the dose of sitravatinib will be escalated to 120 mg and tislelizumab will remain fixed at 200 mg. Approximately 12 to 24 evaluable participants will be treated. The dose of tislelizumab during dose escalation for the combination will be kept fixed at 200 mg
