About this trial
The objective of this study is to compare the efficacy and safety of MRG003 versus cetuximab/methotrexate as second/third line of therapy in patients with RM-SCCHN who have previously failed PD-1 (L1) inhibitors and platinum-based therapy.

Male patients who are willing to use latex condoms during any sexual contact with females of childbearing potential during treatment until 180 days after the last treatment, even if vasectomy has been successfully performed. Reservation of semen specimen prior to the first dose of study treatment is recommended for fertile males for potential future conception.

Trial outcomes
Primary outcomes
Overall Survival (OS)
OS is defined as the duration from the start of treatment to death of any cause.
Secondary outcomes
Progression Free Survival (PFS)
PFS is defined as the duration from the start of treatment to the onset of tumor progression or death of any cause.
Objective Response Rate (ORR)
ORR is defined as the proportions of patients with a complete response (CR) and partial response (PR). ORR will be assessed by investigator according to RECIST v1.1.
Disease Control Rate (DCR)
DCR is defined as the proportion of subjects achieving CR, PR, and SD after treatment.
Duration of Response (DOR)
DOR is defined as the duration from the initial recording of objective disease response to the first onset of tumor progression, or death of any cause.
