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.

Sonidegib and Pembrolizumab in Treating Patients With Advanced Solid Tumors

This phase I trial studies the best dose of sonidegib when given together with pembrolizumab and to see how well they work in treating patients with solid tumor that has spread to other places in the body (advanced). Sonidegib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. 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 sonidegib and pembrolizumab may work better than standard treatment in treating patients with advanced solid tumors.

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.

Trifluridine/Tipiracil and Talazoparib for the Treatment of Patients With Locally Advanced or Metastatic Colorectal or Gastroesophageal Cancer

This phase I trial investigates the side effects and best dose of talazoparib when given together with trifluridine/tipiracil for the treatment of patients with colorectal or gastroesophageal cancer that has spread to nearby tissue or lymph nodes (locally advanced) or other places in the body (metastatic). Drugs used in the chemotherapy, such as trifluridine/tipiracil, 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. Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving talazoparib with trifluridine/ tipiracil may inhibit certain enzymes in the cells that are responsible for tumor cell growth.

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.

S-1 and Oxaliplatin (SOX) Plus Sintilimab in the Locally Advanced Esophagogastric Junction Adenocarcinoma

For locally advanced adenocarcinoma of esophagogastric junction(AEG) (cT3-4aN+M0), neoadjuvant chemotherapy was improved to downstage T and N stage, increase the resectability of tumor, and finally improve the long-term survival. Combination of perioperative PD-1 antibody and chemotherapy for locally advanced AEG could be a novel therapy to increase response rate and resectability and reduce recurrence rate. Sintilimab in this study is an anti-PD-1 monoclonal antibody for injection which has been approved for several malignant tumors. This study is a multi-center, open-label, randomized phase II clinical trial to evaluate tolerability, safety and efficacy of sintilimab in combination with perioperative chemotherapy in locally advanced AEG.
