A Study of HB0030 Injection in Patients With Advanced Solid Tumors

This is a phase Ia single-center, open-label, dose escalation study.The objectives of this study are to evaluate the safety, toxicity, tolerability, pharmacokinetics/pharmacodynamics(PK/PD), immunogenicity, biomarkers, and antitumor activity of HB0030 in advanced solid tumor subjects.
