Metastatic Gastric Cancer

The primary objective of this pharmacokinetics study is to compare the maximum concentration level of paclitaxel in patients with low/sarcopenic skeletal muscle area (SMA), at the end of a 2-3 hour paclitaxel infusion, to the maximum level in patients with normal SMA at the end of a standard 1-hour infusion with the goal of determining whether lengthening the infusion in patients with low/sarcopenic SMA normalizes the levels to those of patients with normal SMA.

This study is being done to learn more about a new medicine called PF-08634404 and how well it works when given with chemotherapy to people with gastroesophageal cancer that is locally advanced (spread to nearby tissues) or has spread to other parts of the body. To join the study, participants must meet the following conditions: Be 18 years or older. Have locally advanced or metastatic gastric, gastroesophageal junction or esophageal adenocarcinoma Be treatment naïve for advanced or metastatic disease Be in good physical condition and have healthy organs based on medical tests. The study has two parts: * In the first part, researchers will check how safe the study medicine in combination with chemotherapy is and how well people respond to it. * In the second part, they will compare study medicine plus chemotherapy to another approved treatment (nivolumab plus chemotherapy) to see which works better. The treatment will be given in repeated time periods called cycles.

This is a phase I, open-label, non-randomized, multicenter, dose-escalation trial designed to evaluate the safety, tolerability, and preliminary anti-tumor activity of autologous p95HER2.CAR-TECH2Me T cells in patients with selected advanced HER2-positive (3+) cancers, including locally advanced, recurrent, or metastatic breast, gastric, endometrial, and other selected solid tumors. The study will also assess pharmacokinetics, pharmacodynamics, and immunogenicity of p95HER2.CAR-TECH2Me following intravenous administration. Treatment consists of non-myeloablative lymphodepletion chemotherapy with cyclophosphamide and fludarabine administered on Days -4 to -2, followed by a single infusion of p95HER2.CAR-TECH2Me cells on Day 0. The investigational product is a live cell suspension of autologous CAR-T lymphocytes derived from the patient's peripheral blood. Premedication will be administered before cell infusion according to protocol requirements. The primary objective of the study is to evaluate the safety and tolerability of p95HER2.CAR-TECH2Me and to identify the maximum tolerated dose (MTD) and recommended Phase II dose (RP2D). Primary endpoints include the nature and frequency of adverse events, serious adverse events, clinically relevant changes in laboratory parameters, electrocardiograms, vital signs, physical examination findings, and ECOG performance status, as well as the incidence and nature of dose-limiting toxicities. Adverse events will be graded according to NCI CTCAE v5.0, with cytokine release syndrome and neurotoxicity graded according to established consensus criteria. Secondary objectives include evaluation of preliminary anti-tumor activity and survival outcomes. Secondary endpoints include objective response rate, duration of response, progression-free survival according to RECIST v1.1 as assessed by the investigator, and overall survival. Approximately 15 patients are planned for enrollment over an estimated 36 to 48 months. The total study duration is expected to be approximately 60 months from the time the first subject signs the pre-screening informed consent form until the last subject completes the final study-related follow-up contact.

The goal of the Dose Escalation phase of the study is to evaluate the safety, tolerability, pharmacokinetics (PK) and preliminary anti-tumor activity to determine the preliminary recommended dose for expansion (RDE) of NKT3964 in adults with advanced or metastatic solid tumors. The goal of the Expansion phase of the study is to evaluate the preliminary anti-tumor activity of NKT3964 at the RDE based on objective response rate (ORR) and determine the preliminary recommended Phase 2 dose (RP2D).

The goal of this Phase II clinical trial is to evaluate the efficacy and safety of Iparomlimab and Tuvonralimab (QL1706) combined with SOX chemotherapy (S-1 plus Oxaliplatin) in patients with previously untreated advanced or metastatic gastric cancer or gastroesophageal junction cancer. The main questions it aims to answer are: 1、What is the objective response rate (ORR) of the combination of QL1706 and SOX chemotherapy? 2、What are the safety and tolerability of this combination therapy? Participants will： 1. Receive Iparomlimab and Tuvonralimab (QL1706) via intravenous infusion every 3 weeks. 2. Receive SOX chemotherapy (Oxaliplatin via intravenous infusion on Day 1 and S-1 orally twice daily for 14 days) every 3 weeks for up to 6 cycles. 3. Continue maintenance therapy with QL1706 combined with S-1 after 6 cycles until disease progression or unacceptable toxicity. 4. Undergo tumor imaging assessments (CT or MRI) every 6 weeks for the first 24 weeks, and then every 9 weeks thereafter to monitor the disease.

This is a multicenter, phase 2, open label study to evaluate safety, tolerability and efficacy of SHR2554 combined with other anti-tumor treatments in patients with advanced or metastatic gastric or gastroesophageal junction adenocarcinoma.

The results of the current studies to determine the optimal strategy for metastatic gastric cancer remain contrversial worldwide. Hypothesis: Cytoreductive Gastrectomy After Systemic Therapy will improve survival time for metastasis gastric cancer compared to Systemic Therapy alone.

This is a Phase II, randomized, multicenter, open-label clinical trial designed to compare Disitamab Vedotin plus Sintilimab and S-1 with Trastuzumab plus chemotherapy ± Sintilimab for first-line treatment of HER2-Positive advanced gastric or gastroesophageal junction adenocarcinoma.

The goal of this evaluate short, medium and long term outcome of the different embolization techniques in patients with primary and secondary hepatic tumors. The main aim is to evaluate progression free survival following embolization in this study population or evaluate residual hepatic volume in cases in which these techniques are used to induce liver regeneration. This study is an observational registry - all patients will follow their normal therapeutic and treatment scheme as per clinical practice, without any additional intervention.

The goal of this clinical trial is to evaluate the efficacy and safety of radiotherapy combined with chemotherapy and anti-PD-1 immunotherapy followed by surgery for the primary and metastatic lesions in patients with limited metastatic gastric or gastroesophageal junction adenocarcinoma. The main questions it aims to answer are: 1) If the multimodal treatment which includes anti-PD-1 immunotherapy and local therapies will improve the survival of this group of patients. 2) If the multimodal treatment which includes anti-PD-1 immunotherapy and local therapies can be performed safely in this group of patients. Participants will receive short course hypofractionated radiotherapy (HFRT) for the primary lesion, HFRT or stereotactic body radiotherapy (SBRT) for metastatic lesions, combined with systemic chemotherapy and anti-PD-1 immunotherapy. For patients with HER2-positive cancer (defined as IHC 3+ or 2+/ISH+), trastuzumab is used along with chemotherapy and anti-PD-1 antibody. Then, surgical resections of primary and metastatic lesions are performed as much as possible. For patients who need a widely invasive surgical approach or are inoperable, local ablative therapies such as radiofrequency ablation (RFA) and microwave ablation (MVA) can be alternatives. For patients undergoing surgical resections, postoperative treatment includes chemotherapy, which is determined by the researcher, and PD-1 antibody, which will be maintained until one year after surgery.

VG161 is a recombinant human-IL12/15/PDL1B oncolytic HSV-1 injection. This study will be conducted in combination with nivolumab injection in HSV seropositive subjects with advanced metastatic gastric or gastroesophageal junction adenocarcinoma who have previously received two or more systemic treatment regimens (which must include anti-PD-1 monoclonal antibodies). This is an open-label study divided into two parts. Part 1: This part is an escalating dose trial to explore the safety of the combination and determine the recommended safe dose of the combination. Part 2: This part is an extension trial to investigate the preliminary efficacy of the combination at a safe dose.

This single-center, prospective study was conducted to investigate the efficacy and safety of palliative surgery after translational therapy in the treatment of metastatic gastric cancer. The primary endpoint was 2-year overall survival (OS) rate. Secondary endpoints were median OS, progression-free survival (PFS), 1-year OS, adverse events (AE), severe AE, the quality of life (QOL) and treatment cost.
