Study Description

Brief Summary:

This is an open-label, dose-escalation study of the study drug YH003 . The study is designed to determine the safety, tolerability and maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of YH003 in subjects with advanced solid tumors.

Condition or disease	Intervention/treatment	Phase
Advanced Solid Tumors	Drug: YH003	Phase 1

Study Design

• Study Type: Interventional (Clinical Trial)
• Actual Enrollment: 16 participants
• Allocation: N/A
• Intervention Model: Single Group Assignment
• Masking: None (Open Label)
• Primary Purpose: Treatment
• Official Title: A Multicenter, Open-label, Phase 1 Dose Escalation Study to Evaluate the Safety, Tolerability, and Pharmacokinetics of YH003 in Subjects With Advanced Solid Tumors
• Actual Study Start Date: August 26, 2021
• Estimated Primary Completion Date: December 2022
• Estimated Study Completion Date: March 2023

Arms and Interventions

Arm	Intervention/treatment
Experimental: Intervention/treatment; All subject will receive YH003 intravenously as single agent every three weeks (Q3W) for up to 1 years, until intolerable toxicity, confirmed disease progression, withdrawal of consent, or Investigator decision, whichever comes first.	Drug: YH003; All subject will receive YH003 intravenously as single agent every three weeks (Q3W) for up to 1 years, until intolerable toxicity, confirmed disease progression, withdrawal of consent, or Investigator decision, whichever comes first.

Outcome Measures

Primary Outcome Measures :

1. Adverse events (AEs) [ Time Frame: up to 1 year after the last dosing ]
   The safety will be assessed by monitoring the adverse events (AE) per NCI CTCAE v5.0
2. Maximum tolerated dose (MTD) and/or Recommended phase 2 dose (RP2D) [ Time Frame: up to 1 year after the last dosing ]
   The MTD and/or RP2D will be determined based on the data of safety and tolerability

Eligibility Criteria

• Ages Eligible for Study: 18 Years and older (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No
