Gastroesophageal Junction Cancer clinical trials at UCSF

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.

The primary purpose of this study is to determine whether Nivolumab will improve disease-free survival compared with placebo.

This pilot phase II trial studies the side effects of CD40 agonistic monoclonal antibody APX005M (APX005M), chemotherapy, and radiation therapy, and to see how well they work when given before surgery in treating patients with esophageal cancer or gastroesophageal cancer that can be removed by surgery. APX005M is intended to stimulate the body's own immune system so that the immune cells can more effectively invade and destroy the tumor, adding to the benefits of the chemotherapy and radiation therapy. Drugs used in chemotherapy, such as carboplatin and paclitaxel, 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. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving APX005M, chemotherapy, and radiation therapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.

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.
