Gastric (Stomach) Cancer Clinical Trials

Clinical trials are research studies that involve people. The clinical trials on this list are for gastric (stomach) cancer. All trials on the list are supported by NCI.

NCI’s basic information about clinical trials explains the types and phases of trials and how they are carried out. Clinical trials look at new ways to prevent, detect, or treat disease. You may want to think about taking part in a clinical trial. Talk to your doctor for help in deciding if one is right for you.

  • Targeted Therapy Directed by Genetic Testing in Treating Patients with Advanced Refractory Solid Tumors, Lymphomas, or Multiple Myeloma (The MATCH Screening Trial)

    This phase II MATCH trial studies how well treatment that is directed by genetic testing works in patients with solid tumors or lymphomas that have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

  • Cisplatin, Carboplatin and Etoposide or Temozolomide and Capecitabine in Treating Patients with Neuroendocrine Carcinoma of the Gastrointestinal Tract or Pancreas That Is Metastatic or Cannot Be Removed by Surgery

    This phase II trial studies how well temozolomide and capecitabine work compared to standard treatment with cisplatin or carboplatin and etoposide in treating patients with neuroendocrine carcinoma of the gastrointestinal tract or pancreas that has spread to other parts of the body (metastatic) or cannot be removed by surgery (unresectable). Drugs used in chemotherapy, such as temozolomide, capecitabine, cisplatin, carboplatin and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Certain types of neuroendocrine carcinomas may respond better to treatments other than the current standard treatment of cisplatin and etoposide. It is not yet known whether temozolomide and capecitabine may work better than cisplatin or carboplatin and etoposide in treating patients with this type of neuroendocrine carcinoma, called non-small cell neuroendocrine carcinoma.

  • Testing the Addition of Radiotherapy to the Usual Treatment (Chemotherapy) for Patients with Esophageal and Gastric Cancer that has Spread to a Limited Number of Other Places in the Body

    This phase III trial studies how well the addition of radiotherapy to the usual treatment (chemotherapy) works compared to the usual treatment alone in treating patients with esophageal and gastric cancer that has spread to a limited number of other places in the body (oligometastatic disease). Radiotherapy uses high energy x-rays, gamma rays, or protons to kill tumor cells and shrink tumors. Drugs used in usual chemotherapy, such as leucovorin, 5-fluorouracil, oxaliplatin, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Adding radiotherapy to the usual chemotherapy may work better compared to the usual chemotherapy alone in treating patients with esophageal and gastric cancer.

  • Olaparib and Ramucirumab in Treating Patients with Metastatic or Locally Recurrent Gastric or Gastroesophageal Junction Cancer That Cannot Be Removed by Surgery

    This phase I / II trial studies the side effects and best dose of olaparib when given together with ramucirumab and how well they work in treating patients with gastric or gastroesophageal junction cancer that has spread to other places in the body (metastatic), has come back (recurrent), or cannot be removed by surgery (unresectable). Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as ramucirumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving olaparib and ramucirumab may work better in treating patients with gastric or gastroesophageal junction cancer compared to ramucirumab and paclitaxel (a chemotherapy drug) or ramucirumab alone.

  • Study of Cabozantinib in Combination With Atezolizumab to Subjects With Locally Advanced or Metastatic Solid Tumors

    This is a multicenter Phase 1b, open-label study to assess safety, tolerability, preliminary efficacy, and pharmacokinetics (PK) of cabozantinib taken in combination with atezolizumab in subjects with multiple tumor types, including advanced urothelial carcinoma (UC) (including bladder, renal pelvis, ureter, urethra), renal cell carcinoma (RCC), castration-resistant prostate cancer (CRPC), non-small-cell lung cancer (NSCLC), triple negative breast cancer (TNBC), ovarian cancer (OC), endometrial cancer (EC), hepatocellular cancer (HCC), gastric cancer / gastroesophageal junction cancer / lower esophageal cancer (GC / GEJC / LEC), colorectal cancer (CRC), head and neck (H&N) cancer, and differentiated thyroid cancer (DTC). The study consists of two stages: in the Dose Escalation Stage, an appropriate recommended cabozantinib dose for the combination with standard dosing regimen of atezolizumab will be established; in the Expansion Stage, tumor-specific cohorts will be enrolled in order to further evaluate the safety and efficacy of the combination treatment in these tumor indications. Three exploratory single-agent cabozantinib (SAC) cohorts may also be enrolled with UC, NSCLC, or CRPC subjects. One exploratory single-agent atezolizumab (SAA) cohort may also be enrolled with CRPC subjects. Subjects enrolled in the SAC cohorts and SAA cohort may receive combination treatment with both cabozantinib and atezolizumab after they experience radiographic progressive disease per the Investigator per RECIST 1.1. Due to the nature of this study design, some tumor cohorts may complete enrollment earlier than others.

  • A Phase 3 Efficacy, Safety and Tolerability Study of Zolbetuximab (Experimental Drug) Plus mFOLFOX6 Chemotherapy Compared to Placebo Plus mFOLFOX6 as Treatment for Gastric and Gastroesophageal Junction (GEJ) Cancer

    A study of zolbetuximab (IMAB362) plus mFOLFOX6 versus placebo plus mFOLFOX6 in subjects with Claudin 18.2 positive, HER2-negative, locally advanced unresectable or metastatic gastric or gastroesophageal junction adenocarcinoma. Why is this study being done? SPOTLIGHT is a new clinical study for adult patients who have any of: - advanced unresectable gastric or GEJ cancer - metastatic gastric or GEJ cancer These types of cancers have a unique set of proteins (called Claudin 18.2). We may be able to use a treatment that targets the proteins to kill the cancer cells. For patients with one of the types of cancer listed above, mFOLFOX6 (a combination of three chemotherapies known as Oxaliplatin, Leucovorin, and Fluorouracil) is a current treatment option. This study is testing an experimental medicine called zolbetuximab (IMAB362). Zolbetuximab attaches itself to Claudin 18.2 on the cancer cells causing cancer cell death. Patients will be assigned to one of two groups by chance and given either: - zolbetuximab with mFOLFOX6; or - a placebo with mFOLFOX6 A placebo is a treatment that looks like the experimental medicine, but contains no medicine. The goal of the study is to find out if zolbetuximab with mFOLFOX6 helps patients to live longer by stopping the cancer from getting worse.
