Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: Phase Ia Dose-Escalation Stage:IBI110; Participants will be treated with escalating doses of IBI110 to determine the MTD.	Drug: IBI110; Several dose levels will be evaluated for IBI110 administered as a single agent and in combination with Sintilimab. IBI110 will be given via intravenous (IV) infusion on Day 1 of each 21-day cycle until disease progression or loss of clinical benefit. Those who discontinue treatment with single-agent IBI110 may receive combination treatment with IBI110 plus Sintilimab. Combination treatment may continue until disease progression or loss of clinical benefit.; Drug: IBI110; IBI110 will be given with RP2D. IBI110 will be given via intravenous (IV) infusion on Day 1 of each 21-day cycle until disease progression or loss of clinical benefit.
EXPERIMENTAL: Phase Ia Expansion Stage:IBI110; Participants will be enrolled in the expansion stage to better characterize the safety, tolerability, PK variability, and preliminary efficacy of IBI110 in different cancer types.	Drug: IBI110; Several dose levels will be evaluated for IBI110 administered as a single agent and in combination with Sintilimab. IBI110 will be given via intravenous (IV) infusion on Day 1 of each 21-day cycle until disease progression or loss of clinical benefit.
