About this trial

This study is a multicenter, single-arm prospective clinical trial designed to evaluate the efficacy of TACE combined with thermal ablation, antibody-drug conjugates, immune checkpoint inhibitors, and first-line chemotherapy for the treatment of HER2 - highly expressing gastric cancer with liver metastases.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Participants voluntarily joined this study, signed informed consent forms, demonstrated good compliance, and cooperated with follow-up.

Male or female, aged 18 or older and 75 or younger;

ECOG score is 0-1;

Expected survival time ≥ 3 months;

Disqualifiers

diagnosed with other malignant tumors within 5 years prior to the first dose and who are not cured (excluding radically resected basal cell carcinoma of the skin, squamous cell carcinoma of the skin, and/or carcinoma in situ that has been radically removed);

Currently participating in interventional clinical research treatment, or having received other investigational drugs or used investigational devices within 4 weeks prior to the first dose;

Previous treatment with the following: antibody-drug conjugates, anti-PD-1, anti-PD-L1 or anti-PD-L2 drugs or drugs that stimulate or co-inhibit T cell receptors (e.g. CTLA-4, OX-40, CD137);

Within 28 days prior to the first administration of the study drug, the target lesion had received local treatment (including transarterial chemoembolization/TACE, hepatic artery infusion chemotherapy/TAC, radiotherapy, radioembolization or ablation, etc.);

Trial design

Design model

Single group

Treatments tested in this trial

  • TACE combined with thermal ablation

    Other intervention

    The decision to perform transarterial chemoembolization (TACE) and/or thermal ablation is based on the blood supply, size, and number of liver metastases as determined by imaging examinations. Interventional therapy is repeated every two cycles, and TACE and/or thermal ablation therapy are selected based on the blood supply, location, size and number of liver metastases.

  • Targeted Therapy

    Drug

    Disitamab Vedotin For Injection: 2.5 mg/kg, day 1, IV drip , Q3W.

  • Immunotherapy

    Drug

    Sintilimab : 200mg , d1 , ivdrip , q3w

  • Chemotherapy

    Drug

    S-1 : 40-60 mg/dose, orally, twice daily (bid), daily (days 1-14) , every 3 weeks (q3w).
