A Phase I, Multi-center, Open-label Study with Dose-escalation and Multiple Expansion Cohorts to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Antitumor Activity of JYB1907 in Subjects with Advanced Solid Tumors

Dose escalation This part is meant to evaluate the safety, tolerability, PK, immunogenicity, preliminary antitumor activity, the MTD and RP2D of JYB1907 in patients with histologically or cytologically confirmed advanced solid tumors.

Expansion cohort The antitumor activity, safety, tolerability, PK and immunogenicity of JYB1907 will be further evaluated in other cohorts.
