Advanced Solid Tumors
Conditions
Brief summary
This is an open-label, dose escalation, Phase I study to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, immunogenicity and efficacy of single agent of IBI310, and in combination of sintilimab, in patients with advanced solid tumors(Ia) and advanced melanoma(Ib).
Detailed description
Phase Ia study will adopt the classical 3+3 dose escalation design. The starting dose is 0.3 mg/kg, followed by 3 dose cohorts (1mg/kg, 2mg/kg and 3mg/kg). Duration of dose limiting toxicity (DLT) observation period is 21 days. IBI310 treatment q3w, up to 3 cycles, will be provided to patients who complete DLT observation period. Efficacy will primarily be evaluated by RECIST v1.1. Patient safety will be monitored throughout the study. Pharmacokinetic/pharmacodynamics and immunogenicity will be assessed throughout the study. Phase Ib study will evaluate the tolerability and safety of IBI310 combined with Sintilimab in patients with advanced melanoma. Phase Ib of the study will begin after DLT observation is completed in certain dose cohorts.
