Study Overview
Brief Summary
The objective of this study is to assess the safety and tolerability of MRG002 in combination with HX008 in patients with HER2-expressed advanced malignant solid tumors; and to , explore the maximum tolerated dose (MTD), and to determine the recommended phase II dose (RP2D) of combination therapy; , and to evaluate the preliminary efficacy, pharmacokinetics, and immunogenicity of combination therapy in the targeted study population.

Arms & Interventions
MRG002+HX008
MRG002 will be administrated via intravenous infusion at 1.8，,2.2, or 2.6 mg/kg , (if appropriate) once on Day 1 of every 3 weeks (21-day cycle), up to 24 months.
HX008 will be administrated via intravenous infusion at 3 mg/kg once on Day 1 of every 3 weeks (21-day- cycle), up to 24 months.
Intervention: MRG002+HX008 (Drug)
Outcomes
Primary Outcomes
Incidence of dose limiting toxicity (DLT) in each dose group
Time Frame: Within 28 days after the first dose.
DLT is defined as any of the treatment emergent adverse events (TEAE) as specified in the protocol that bear a definite, probable, or possible causal relationship to study drug administration within 28 days after the first dose.
Adverse events
Time Frame: After signing informed consent until 90 days after the last dose.
Any reaction, side effect, or untoward event that occurs during the course of the clinical trial whether or not the event is considered related to the study drug.
Recommended Phase II Dose (RP2D)
Time Frame: Baseline to study completion (up to 24 months)
The dose level of MRG002 recommended for further clinical studies based on assessment of the safety, efficacy and PK data from this study.
Secondary Outcomes
- Progression Free Survival (PFS)(Baseline to study completion (up to 24 months))
- Overall Survival (OS)(Baseline to study completion (up to 24 months))
- Time to Response (TTR)(Baseline to study completion (up to 24 months))
- Objective Response Rate (ORR)(Baseline to study completion (up to 24 months))
- Duration of Response (DOR)(Baseline to study completion (up to 24 months))
- PK parameters: concentration-time curve(Baseline to 90 days after the last dose.)
- Immunogenicity (ADA)(Baseline to 90 days after the last dose.)
- Disease Control Rate (DCR)(Baseline to study completion (up to 24 months))
