Adding Nivolumab to Usual Treatment for People With Advanced Stomach or Esophageal Cancer, PARAMUNE Trial
This phase II/III trial compares the addition of nivolumab to the usual treatment of paclitaxel and ramucirumab to paclitaxel and ramucirumab alone in treating patients with gastric or esophageal adenocarcinoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Ramucirumab is a monoclonal antibody that may prevent the growth of new blood vessels that tumors need to grow. Paclitaxel is in a class of medications called antimicrotubule agents. It stops cancer cells from growing and dividing and may kill them. Adding nivolumab to ramucirumab and paclitaxel may work better to treat patients with advanced stomach or esophageal cancer.

Testing the Combination of Two Anti-cancer Drugs, DS-8201a and AZD6738, for The Treatment of Advanced Solid Tumors Expressing the HER2 Protein or Gene, The DASH Trial
The dose escalation phase of this trial identifies the safety, side effects and best dose of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how colorectal and gastroesophageal cancers with HER2 mutation respond to treatment with a combination of ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone. Ceralasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Ceralasertib and trastuzumab deruxtecan may be safe, tolerable and effective in treating patients with advanced solid tumors expressing the HER2 protein or gene.

Testing the Combination of the Anticancer Drugs Trastuzumab Deruxtecan (DS-8201a) and Azenosertib (ZN-c3) in Patients With Stomach or Other Solid Tumors
This phase I trial tests the safety, side effects, and best dose of azenosertib in combination with trastuzumab deruxtecan in treating patients with HER2-positive gastric or gastroesophageal junction cancer and other HER2-positive solid tumors that have spread to nearby tissue or lymph nodes (locally advanced), that have spread from where it first started (primary site) to other places in the body (metastatic), or that cannot be removed by surgery (unresectable). Azenosertib is in a class of medications called kinase inhibitors. It inhibits a protein called Wee1. Inhibition of the Wee1 protein can make tumor cells more vulnerable to chemotherapy drugs, leading to tumor cell death. Trastuzumab deruxtecan is in a class of medications called antibody-drug conjugates. It is composed of a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Giving azenosertib in combination with trastuzumab deruxtecan may be safe, tolerable, and/or more effective in treating patients with locally advanced, metastatic, or unresectable HER2-positive gastric, gastroesophageal junction, or other solid tumors, compared to just trastuzumab deruxtecan alone.

Berzosertib and Irinotecan in Treating Patients With Progressive, Metastatic, or Unresectable TP53 Mutant Gastric or Gastroesophageal Junction Cancer
This phase II trial studies the how well berzosertib and irinotecan work in treating patients with gastric or gastroesophageal junction cancer that is growing, spreading or getting worse (progressive), has spread to other places in the body (metastatic), or cannot be removed by surgery (unresectable). Berzosertib may stop the growth of tumor cells by blocking some of the enzymes needed for growth. Chemotherapy drugs, such as irinotecan, 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. Giving berzosertib and irinotecan may work better than irinotecan alone in treating patients with gastric and gastroesophageal junction cancer.

mFOLFIRINOX Versus mFOLFOX With or Without Nivolumab for the Treatment of Advanced, Unresectable, or Metastatic HER2 Negative Esophageal, Gastroesophageal Junction, and Gastric Adenocarcinoma
This phase III trial compares the effect of modified fluorouracil, leucovorin calcium, oxaliplatin, and irinotecan (mFOLFIRINOX) to modified fluorouracil, leucovorin calcium, and oxaliplatin (mFOLFOX) for the treatment of advanced, unresectable, or metastatic HER2 negative esophageal, gastroesophageal junction, and gastric adenocarcinoma. The usual approach for patients is treatment with FOLFOX chemotherapy. Chemotherapy drugs 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. Fluorouracil stops cells from making DNA and it may kill tumor cells. Leucovorin is used with fluorouracil to enhance the effects of the drug. Oxaliplatin works by killing, stopping, or slowing the growth of tumor cells. Some patients also receive an immunotherapy drug, nivolumab, in addition to FOLFOX chemotherapy. Immunotherapy may induce changes in body's immune system and may interfere with the ability of tumor cells to grow and spread. Irinotecan blocks certain enzymes needed for cell division and DNA repair, and it may kill tumor cells. Adding irinotecan to the FOLFOX regimen could shrink the cancer and extend the life of patients with advanced gastroesophageal cancers.

Personalized Neoantigen Peptide-Based Vaccine in Combination With Pembrolizumab for Treatment of Advanced Solid Tumors
This phase I/II trial tests the safety and tolerability of an experimental personalized vaccine when given by itself and with pembrolizumab in treating patients with solid tumor cancers that have spread to other places in the body (advanced). The experimental vaccine is designed target certain proteins (neoantigens) on individuals' tumor cells. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving the personalized neoantigen peptide-based vaccine with pembrolizumab may be safe and effective in treating patients with advanced solid tumors.

Pembrolizumab and Chemoradiotherapy for the Treatment of Unresectable Gastroesophageal Cancer
This phase I trial investigates how well pembrolizumab and chemoradiotherapy works in treating patients with gastroesophageal cancer that cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as fluorouracil, oxaliplatin and docetaxel 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 photons to kill tumor cells and shrink tumors. Giving pembrolizumab together with chemoradiotherapy may help to control gastroesophageal cancer.

Testing the Addition of the Anti-cancer Viral Therapy Telomelysin™ to Chemoradiation for Patients With Advanced Esophageal Cancer and Are Not Candidates for Surgery
This phase I trial studies the side effects of OBP-301 when given together with carboplatin, paclitaxel, and radiation therapy in treating patients with esophageal or gastroesophageal cancer that invades local or regional structures. OBP-301 is a virus that has been designed to infect and destroy tumor cells (although there is a small risk that it can also infect normal cells). Chemotherapy drugs, 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 OBP-301 with chemotherapy and radiation therapy may work better than standard chemotherapy and radiation therapy in treating patients with esophageal or gastroesophageal cancer.

Propranolol in Combination With Pembrolizumab and Standard Chemotherapy for the Treatment of Unresectable Locally Advanced or Metastatic Esophageal or Gastroesophageal Junction Adenocarcinoma
This phase II trial tests what effects the addition of propranolol to pembrolizumab and standard chemotherapy (mFOLFOX) may have on response to treatment in patients with esophageal or gastroesophageal junction cancer that cannot be removed by surgery and has spread to nearby tissue or lymph nodes (unresectable locally advanced) or has spread from where it first started (primary site) to other places in the body (metastatic). Propranolol is a drug that is classified as a beta-blocker. Beta-blockers affect the heart and circulation (blood flow through arteries and veins). Cancer patients may be under a tremendous amount of stress with elevated levels of norepinephrine (a hormone produced by the adrenal glands in response to stress). Increased adrenergic stress may dampen the immune system, which beta-blockers, like propranolol, may be able to counteract. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in the standard chemotherapy regimen, mFOLFOX (leucovorin, fluorouracil and oxaliplatin) 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 propranolol to pembrolizumab and standard mFOLFOX chemotherapy may increase the effectiveness of the pembrolizumab + mFOLFOX regimen.

Testing the Addition of an Anti-cancer Drug, Adavosertib, to Radiation Therapy for Patients With Incurable Esophageal and Gastroesophageal Junction Cancers
This phase I trial investigates the side effects and best dose of adavosertib and how well it works when given in combination with radiation therapy in treating patients with esophageal or gastroesophageal junction cancer for which no treatment is currently available (incurable). Adavosertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving adavosertib together with radiation therapy kill more tumor cells than radiation therapy alone in treating patients with esophageal and gastroesophageal junction cancer.
