New drug duo takes aim at hard-to-treat stomach cancer with liver metastases
NCT ID NCT07677293
First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This phase 3 trial compares a new drug called Retlirafusp alfa plus chemotherapy against standard immunotherapy plus chemotherapy for people with advanced stomach or gastroesophageal junction cancer that has spread to the liver and has not been treated before. The study aims to see if the new combination helps people live longer without their cancer growing. About 332 participants will be randomly assigned to one of the two treatment groups.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Retlirafusp alfa
- What this could lead to
- If successful, this could offer a new first-line treatment option for people with advanced gastric cancer that has spread to the liver.
- What could go wrong
- This is an early-phase 3 trial, so results may not confirm benefit. The experimental drug may cause side effects or not improve outcomes compared to existing therapies.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 1\. Age ≥ 18 years; 2. Patients with recurrent or previously untreated advanced gastric or gastroesophageal junction cancer with liver metastases, histopathologically confirmed as adenocarcinoma. 3\. No prior systemic therapy (including anti-HER2 therapy) for advanced or metastatic GC/GEJC. Patients who have received prior adjuvant or neoadjuvant therapy are eligible provided that the time from completion of last therapy to first recurrence or disease progression is \> 6 months. 4\. Eastern Cooperative Oncology Group (ECOG) performance status of 0-1. 5. At least one evaluable lesion according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. 6\. Adequate organ and bone marrow function. 7. Female subjects of non-childbearing potential are defined as those who are postmenopausal, or have undergone documented hysterectomy and/or bilateral oophorectomy. Male subjects and female subjects of childbearing potential must agree to use at least one medically approved contraceptive method during the study and for 120 days after the last dose of study treatment. A serum pregnancy test must be negative within 3 days prior to the start of study treatment, and subjects must not be breastfeeding. 8\. Voluntarily signed informed consent, and willing and able to comply with scheduled visits, study treatment, laboratory tests, and other study procedures. Exclusion Criteria: * 1\. Known gastric cancer of squamous cell carcinoma, undifferentiated carcinoma, or other histological types, or adenocarcinoma mixed with other histological types. 2\. Untreated or inadequately treated central nervous system (CNS) metastases, or uncontrolled or symptomatic active CNS metastases. 3\. Diagnosis of any other malignancy within 5 years prior to study entry, except for: skin basal cell carcinoma or squamous cell carcinoma that has been locally treated and documented as cured, superficial bladder cancer, cervical carcinoma in situ, breast ductal carcinoma in situ, papillary thyroid carcinoma, and other early-stage tumors with low risk of recurrence that have undergone curative treatment as judged by the investigator. 4\. Presence of any active, known, or suspected autoimmune disease. 5. Prior treatment with TGF-β inhibitors, anti-PD-1/PD-L1 antibodies, anti-PD-L2 antibodies, anti-CD137 antibodies, CTLA-4 antibodies, or other drugs/antibodies targeting T-cell costimulatory or checkpoint pathways. 6\. Severe, non-healing, or dehiscent wound, or active ulcer, or untreated fracture. 7\. Any other serious physical or mental illness, or laboratory abnormalities that may increase the risk of study participation, interfere with study results, or render the subject unsuitable for the study judged by the investigator.
