Advanced Malignant Solid Tumors Clinical Trial
Official title:
An Open-label, Multi-center, Phase I/II Dose Escalation and Expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Efficacy of MRG002 in Combination With HX008 in Patients With HER2-expressed Advanced Malignant Solid Tumors.
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.
