Brief Summary:

This is a study to evaluate the safety and tolerability of the study drug HBM4003, and to determine the maximum tolerated dose and/or recommended Phase 2 study dose of HBM4003. The study will also look at the anti-tumor activity of HBM4003.The study consists of 2 parts. In Part 1, patients are enrolled into different cohort doses in order to identify the appropriate recommended phase 2 dose (RP2D) or maximum tolerated dose (MTD). In Part 2, participants with metastatic/unresectable melanoma will receive the MTD and/or RP2D established in Part 1 of the study. In Part 1 and Part 2, participants will be administered treatment either once per week or once every 3 weeks.

NOTE: Participants are no longer being recruited to this study.
