A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety, efficacy, pharmacokinetics, and immunogenicity of MRG003 in combination with HX008 for patients with EGFR-positive advanced or metastatic solid tumors. It consists of two phases: Phase I focuses on determining the maximum tolerated dose and safety profile, while Phase II assesses preliminary efficacy and pharmacokinetics. Patients will be monitored for their response to the treatment and any adverse effects.
