Conditions
Summary
This prospective, multicenter clinical study aims to evaluate the efficacy and safety of neoadjuvant therapy with MRG003 (Becotatug vedotin) combined with epirubicin in patients with EGFR-positive, unresectable recurrent sinonasal adenoid cystic carcinoma (SNACC). The primary question is whether this combination can achieve a sufficient objective response rate (ORR) to enable subsequent radical surgery or improve disease control.

Interventions
Becotatug vedotin (also known as MRG003) is an antibody-drug conjugate (ADC) targeting epidermal growth factor receptor (EGFR). It consists of a recombinant anti-EGFR humanized monoclonal antibody conjugated to the microtubule-disrupting agent monomethyl auristatin E (MMAE) via a valine-citrulline linker. It is administered intravenously at 2.0 mg/kg on day 1 of each 21-day cycle for 3 cycles. Epirubicin is an anthracycline chemotherapeutic agent that inhibits topoisomerase II, thereby interfering with DNA replication and transcription. It is administered intravenously at 75 mg/m² on day 1 of each 21-day cycle for 3 cycles.
