Gastric Cancer Clinical Trials

This study is a first in human Phase 1 study that involves patients with a type of cancer called HER2 (Human Epidermal Growth Factor Receptor 2) positive cancer. This study asks patients to volunteer to take part in a research study investigating the safety and efficacy of using special immune cells called HER2 chimeric antigen receptor specific cytotoxic T lymphocytes (HER2 specific CAR T cells), in combination with intra-tumor injection of CAdVEC, an oncolytic adenovirus that is designed to help the immune system including HER2 specific CAR T cell react to the tumor. The study is looking at combining these two treatments together, because we think that the combination of treatments will work better than each treatment alone. We also hope to learn the best dose level of the treatments and whether or not it is safe to use them together. In this study, CAdVEC will be injected into participants tumor at one tumor site which is most easiest to reach. Once it infects the cancer cells, activation of the immune response will occur so it can attack and kill cancer cells. (This approach may have limited effects on the other tumor sites that have not received the oncolytic virus injection, so, patients will also receive specific T cells following the intratumor CAdVEC injection.) These T cells are special infection-fighting blood cells that can kill cells infected with viruses and tumor cells. Investigators want to see if these cells can survive in the blood and affect the tumor. Both CAdVEC and HER2-specific autologous CAR T are investigational products. They are not approved by the FDA.

Participants will a diagnosis of gastroesophageal junction (GEJ) adenocarcinoma and will have either a minimally invasive proximal gastrectomy (MIPG) or a minimally invasive total gastrectomy (MITG) as part of their routine care. Participants with complete a questionnaire 1 month before the surgical procedure and then 1, 3, 6 and 12 months after the surgical procedure. Read Less

This is a First-in-Human Phase IA/IB/II open label dose escalation study of intravenous (IV) administration of ONC-392, a humanized anti-CTLA4 IgG1 monoclonal antibody, as single agent and in combination with pembrolizumab in participants with advanced or metastatic solid tumors and non-small cell lung cancers.

This is Phase 1 dose finding trial with potential dose expansion to evaluate the safety, toxicity, recommended phase 2 dose (RP2D), and maximum tolerated dose (MTD) of Neratinib plus TDxD using a standard 3+3 dose escalation design in patients with metastatic or unresectable gastro-esophageal cancer that are HER2-overexpressing (IHC 3+ or IHC2+/ISH+) and any other gastrointestinal cancer with HER2 expression with IHC3+. Patients must have progressed or been intolerant of at least one prior line of chemotherapy + HER2 directed therapy. Read Less

This Phase 2b, multicohort, open-label clinical trial (QUILT-3.055) evaluates combination immunotherapies in patients with various advanced solid tumors who have progressed following prior PD-1/PD-L1 checkpoint inhibitor therapy. The trial includes six cohorts: Cohorts 1-4: Patients who progressed after an initial response (PR or CR) to prior PD-1/PD-L1 therapy, receiving combination therapy with N-803 and a PD-1/PD-L1 checkpoint inhibitor. (Closed to enrollment) Cohort 5: Patients who progressed while receiving treatment in cohorts 1-4; they receive combination therapy with N-803, a PD-1/PD-L1 checkpoint inhibitor, and PD-L1 t-haNK cells.(Closed to enrollment) Cohort 6A \& 6B: Patients with acquired resistance to prior PD-1/PD-L1 therapy; they receive combination therapy with N-803, docetaxel, and either pembrolizumab (6A) or nivolumab (6B). Treatment is administered for up to two years or until disease progression, and participants are closely monitored for adverse events (AEs), including immune-related AEs, with specific dose modifications outlined. The primary endpoint is objective response rate (ORR) assessed by RECIST v1.1. The study uses Simon's two-stage design for cohorts 1-3 to determine the optimal dose and further assesses safety and efficacy endpoints for all cohorts. Read Less

This is a Phase 1/2 open-label, multi-center, multi-national study with an initial dose escalation part to determine the recommended Phase II dose (RP2D) of MCLA-158 single agent in patients with mCRC. The dose escalation part has been completed and the RP2D will be further evaluated in an expansion part of the study. Cohorts of selected solid tumor indications for which there is evidence of EGFR dependency and potential sensitivity to EGFR inhibition will be evaluated including head and neck cancer and metastatic colorectal cancer (mCRC). The study will further assess the safety, tolerability, PK, PD, immunogenicity, and anti-tumor activity of MCLA-158 in monotherapy or in combination with other therapies. Read Less

This study is to identify potential biomarkers for the early detection of Barrett's Esophagus, esophageal carcinoma (both adenocarcinoma and squamous cell carcinoma), and gastric cancer via sponge cytology. Read Less

The purpose of the study is to test the effects, both good and bad, of the research study drug Neratinib in combination with Trastuzumab, Pembrolizumab and FOLFOX chemotherapy. This study will also look at the safety of Neratinib in combination with Trastuzumab, Pembrolizumab and FOLFOX in HER2 overexpressing Gastroesophageal cancers. Read Less

This is a phase I trial of CA-4948 in combination with FOLFOX/PD-1 inhibitor with or without trastuzumab for unresectable gastric, GEJ, and esophageal cancer. During the Dose Escalation portion of the study, different dose levels of CA-4948 in combination with FOLFOX/nivolumab will be evaluated by BOIN algorithm. Dose Expansion will include Cohorts A and B. Expansion Cohort A will enroll up to 12 patients with HER2 negative gastric, GEJ, and esophageal cancer at the expansion dose of CA-4948 determined during Dose Escalation and will use the same treatment regimen of FOLFOX/nivolumab. Expansion Cohort B will investigate CA-4948 at the dose determined during Dose Escalation in combination with FOLFOX/pembrolizumab and trastuzumab in up to 12 patients with HER2 positive disease; however, the initial 6 patients will be considered safety lead-in to confirm the safety and tolerability of this combination; if determined to be safe, an additional 6 patients will be enrolled for a total of 12 in Cohort B.

The overall goal of this feasibility study is to assess the initial safety and efficacy of LUM015 in ex vivo far-red imaging of colorectal, pancreatic, and esophageal cancers (adenocarcinoma) using the LUM Imaging System. Read Less

The investigators propose to evaluate the safety of drug combinations in patients with advanced gastroesophageal cancer and other gastrointestinal (GI) malignancies. Finding effective novel therapies for patients with advanced gastric cancer and other GI malignancies is an area of great unmet need. The investigators believe that modulating the tumor microenvironment with biologic agents like cabozantinib will have synergistic effect when combined with checkpoint-based immunotherapeutics like durvalumab in this patient population. This is a phase I/II, open label, multi-cohort trial looking at safety, tolerability and efficacy endpoints. Read Less

This is a phase II clinical trial assessing the safety and efficacy of sequential systemic and intraperitoneal (IP) chemotherapy in patients with primary gastric/gastroesophageal junction cancer with cytology positive peritoneal lavage and/or peritoneal carcinomatosis. Read Less
