Study Description

Brief Summary:

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.

Condition or disease	Intervention/treatment	Phase
Advanced Solid Tumor	Drug: HB0030 injection	Phase 1

Detailed Description:

The phase Ia study will enroll up to 19-36 subjects with advanced solid tumor who have progressing tumor after standard therapy and have no better treatment option.The conventional 3+3 design will be applied for dose escalation.This study will set up 8 dose groups.HB0030 injection is administered once every 3 weeks.

Study Design

• Study Type: Interventional (Clinical Trial)
• Estimated Enrollment: 36 participants
• Allocation: Non-Randomized
• Intervention Model: Sequential Assignment
• Intervention Model Description: Subjects were enrolled from low to high doses.
