NCT05898373

Brief Summary

(1) To apply Bayesian statistics to screen for the most effective treatment regimen containing recombinant humanized anti-HER2 monoclonal antibody-MMAE coupling agent vedicitumomab (Edisil, RC48) for locally advanced or metastatic salivary gland ductal carcinoma expressing HER2 in the near future. (2) To explore biomarkers relevant to the efficacy of recombinant humanized anti-HER2 monoclonal antibody-MMAE-coupled vedicitumomab (Edisil, RC48) in the treatment of HER2-expressing locally advanced or metastatic salivary gland ductal carcinoma.
