About this trial
This is a single-arm, single-center, exploratory clinical study. The study plans to enroll patients with recurrent or metastatic head and neck salivary gland carcinoma (HN-SGC) . The trial comprises two cohorts: Cohort 1 (adenoid cystic carcinoma, ACC) and Cohort 2 (non-ACC SGC). Patients in Cohort 1 will initially receive MRG003, an EGFR-targeted antibody-drug conjugate (ADC). Patients in Cohort 2 will initially receive either MRG003 (EGFR-ADC) or a TROP2-targeted ADC. The selection between these two ADC therapies for Cohort 2 will be determined by the investigator based on the expression levels of specific tumor surface receptors.
Tumor response will be assessed by imaging every 6 weeks (±7 days). Subjects who are assessed as having stable disease (SD) on two consecutive evaluations or who develop oligometastatic progression will receive stereotactic body radiation therapy (SBRT). Following SBRT, maintenance therapy with the original ADC will be continued.
Treatment discontinuation will be permitted due to disease progression, death, intolerable toxicity, withdrawal of consent, initiation of new anti-tumor therapy, or other protocol-specified reasons, whichever occurs first. After treatment completion, all subjects will enter a post-treatment phase for safety visits and survival follow-up. For subjects who discontinue treatment for reasons other than disease progression or death, tumor progression follow-up will also be conducted during the post-treatment period.
Eligibility criteria
Qualifiers
Provide written informed consent prior to the initiation of any study-specific procedures.
Male or female patients aged 18-80 years.
Histologically or cytologically confirmed head and neck squamous cell carcinoma or adenoid cystic carcinoma, expressing ADC-related targets (e.g., EGFR, TROP2), with evidence of recurrence and/or metastasis.
Patients must have experienced disease progression after first-line standard therapy or be deemed unsuitable for such therapy, and meet the following conditions: (1) For adenoid cystic carcinoma, first-line treatment should include anti-angiogenic agents (e.g., TKIs or monoclonal antibodies), chemotherapy, or patients are considered unsuitable for standard first-line therapy by the investigator (e.g., high bleeding risk, non-healing wounds); (2) For other salivary gland carcinomas, patients must have progressed after first-line standard therapy or be unsuitable for such therapy.
Disqualifiers
Diagnosis of malignancies other than head and neck tumors within 5 years prior to the first dose (except for adequately treated basal cell carcinoma of the skin, squamous cell carcinoma of the skin, and/or carcinoma in situ following curative resection).
Participation in another interventional clinical study or receipt of investigational drugs/devices within 4 weeks prior to the first dose.
Prior treatment with ADC agents.
Treatment of traditional Chinese medicines with antitumor indications or immunomodulatory agents (e.g., thymosin, interferon, interleukins; except for local use for pleural effusion control) within 2 weeks prior to the first dose.
