New hope for stomach cancer patients with abdominal spread: experimental drug combo enters trial
NCT ID NCT07384234
First seen Jun 24, 2026 · Last updated Jul 24, 2026 · Updated 3 times
Summary
This phase 2 trial is testing whether adding an experimental immunotherapy drug called SHR-1701 to standard chemotherapy can help people with stomach cancer that has spread to the lining of the abdomen. The study will enroll 60 adults and compare two different chemotherapy combinations, with or without SHR-1701. The main goal is to see if the treatment improves survival over two years and whether it can make the cancer removable by surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- SHR-1701 (an experimental immunotherapy drug) combined with chemotherapy drugs (paclitaxel, S-1, capecitabine, oxaliplatin)
- What this could lead to
- If successful, this could offer a new treatment option for people with stomach cancer that has spread to the abdomen, potentially improving survival and making surgery possible.
- What could go wrong
- This is an early phase 2 trial with only 60 participants, so results are preliminary. The combination may cause significant side effects, and the experimental drug SHR-1701 may not improve outcomes over standard chemotherapy.

Inclusion Criteria: 1. Age ≥ 18 years old. 2. Pathologically confirmed gastric or gastroesophageal junction adenocarcinoma (Siewert typeⅡ and type Ⅲ gastroesophageal junction adenocarcinoma are eligible for inclusion). 3. Definitively diagnosed with peritoneal metastasis by exploratory laparoscopy and/peritoneal lavage cytology (CY0P1/CY1P0/CY1P1 are eligible, ovarian metastasis is permitted), and without gastric outlet obstruction or intestinal obstruction. 4. No prior anti-tumor treatment history (including radiotherapy, chemotherapy, targeted therapy, immunotherapy, etc.). 5. Eastern Cooperative Oncology Group (ECOG) performance status score of 0-1. 6. Normal function of major organs. Exclusion Criteria: 1. Known HER2-positive. 2. Previous history of gastric cancer surgery. 3. Contraindications to surgical treatment or chemotherapy, or poor physical status and organ function precluding major abdominal surgery. 4. Presence of distant metastases other than peritoneal metastases (e.g., liver, lung, ovarian, para-aortic lymph node, brain metastases, etc.). 5.
