Nutrition Intervention Trials in Linxian Follow-up Study

Two large, nutritional intervention trials were conducted in Linxian, China between 1985-1991. These trials tested the effect of multiple vitamins and minerals in the prevention of esophageal cancer in a population with the highest known rate for this disease in the world. Results from the trials showed that Beta-carotene + Vitamin E + selenium reduced total mortality, total cancer mortality, and stomach cancer incidence and mortality. Multivitamins/minerals also showed reduction in premalignant lesions. Preliminary follow-up data obtained for the time period after cessation of intervention in 1991 suggests that the observed benefit for total and cancer mortality is reduced but that the benefit for stomach cancer remains. The objectives of the follow-up study are: (1) to continue to determine cancer incidence and all causes of mortality in trial participants after intervention to permit examination of potential effects of the interventions on total and cause-specific mortality and cancer incidence in the post-intervention period; (2) to conduct a cross-sectional nutritional survey in a subsample of living trial participants to evaluate their nutritional status, asses the validity of dietary questionnaires, and relate neurologic status to vitamin B12 plasma levels; (3) to collect a blood sample from all living trial participants to permit further etiologic investigations of genetic and environmental hypotheses; and (4) to perform nested case-control studies of selected genetic and environmental hypotheses. To accomplish the objectives of the follow-up study, we will: (1) determine updated vital status and cancer status data on all trial participants via monthly checks of village doctor records and quarterly checks of the Linxian Cancer Registry; conduct a Vital/Cancer Status Interview Survey among all (n-34,000 trial participants (or their surrogates); identify, collect, and store all available diagnostic materials for trial participants identified as having developed cancer or died with cancer during the follow-up period; (2) conduct a Nutritional Survey on a subsample (n-1000) of living trial participants that will include (a) a physical exam and brief medical history, (b) a neurologic history, (c) a cognitive function exam, (d) a hair/mouth skin exam, (e) a neurological exam, (f) a nutritional questionnaire, and (g) collection of a blood sample for hematologic/biochemical analyses; (3) conduct a Blood Collection Survey of all living trial participants (n-23,000) to obtain (a) a physical exam and brief medical history and (b) a single 10-ml blood sample for separation and preservation as WBCs (both viable and nonviable), RBCs, and plasma for genetic (e.g., xenobiotic polymorphisms) and environmental (e.g., plasma ascorbic acid) hypothesis testing; and (4) perform Nested Case-Control Studies of selected genetic and environmental hypothesis related to the etiology and prevention of esophageal cancer and stroke. These will be done using serum from the new cancer and stroke cases (-2500) and controls (-2500) previously identified from 1991-1996, as well as using new cancer and stroke cases and controls for the period 1996-2004 (-9000). The followup for endpoints will continue monthly for an additional 5 years (through the year 2003). The Nutritional Survey and Blood Collection Survey will be conducted in the spring of 1999. The Nested Case-Control studies will be performed annually beginning in 2000, and the Vital/Cancer Interview Survey will be conducted in the Spring of 2001.

IDOV-Immune for Advanced Solid Tumors

This is a Phase I clinical trial evaluating an investigational treatment called IDOV-Immune, a type of oncolytic virus therapy, for adults with advanced solid tumors that have not responded to standard treatments. Oncolytic viruses are designed to infect and destroy cancer cells and have the potential to stimulate the immune system to fight the tumor. The purpose of this study is to determine the safety of IDOV-Immune, how well it is tolerated, and to identify the highest dose that can be safely given. Researchers will also study how the drug behaves in the body, how the immune system responds to it, and whether it shows any signs of shrinking tumors. Participants will receive a single intravenous (IV) infusion of IDOV-Immune and will be closely monitored for side effects and any changes in their cancer. This study is being conducted at multiple sites in the United States and Australia.

A Phase 2 Study of Zanidatamab in Patients With HER2-expressing Tumors

The purpose of this study is to evaluate the efficacy and safety of zanidatamab for the treatment of participants with previously treated solid tumors that have Human Epidermal Growth Factor Receptor 2 (HER2) Immunohistochemistry (IHC) 3+ overexpression.

Ph1b/2 Study of the Safety and Efficacy of T-DXd Combinations in Advanced HER2-expressing Gastric Cancer (DESTINY-Gastric03)

DESTINY-Gastric03 will investigate the safety, tolerability, pharmacokinetics, immunogenicity, and preliminary antitumor activity of trastuzumab deruxtecan (T-DXd) alone or in combination with chemotherapy and/or immunotherapy in HER2-expressing advanced/metastatic gastric/gastroesophageal junction (GEJ) and esophageal adenocarcinoma patients. Study hypotheses: Combination of T-DXd with cytotoxic chemotherapy and/or immunotherapy administered to subjects at the recommended phase 2 dose will show manageable safety and tolerability and preliminary anti-tumor efficacy so as to permit further clinical testing. T-DXd in combination with cytotoxic chemotherapy or immune checkpoint inhibitor administered to HER2-expressing gastric, GEJ and esophageal cancer patients who have not received prior treatment for advanced/metastatic disease will show preliminary evidence of anti-tumour activity and the potential to become a therapeutic option for this patient population.

Becotatugvedotin Plus Pucotenlimab in EGFR-Positive Advanced Gastric/GEJ Adenocarcinoma

Advanced gastric cancer (AGC) and gastroesophageal junction (GEJ) adenocarcinoma remain associated with poor prognosis after failure of first-line systemic therapy. Although immune checkpoint inhibitor-based chemoimmunotherapy has become the standard first-line treatment for HER2-negative advanced disease, most patients eventually experience disease progression. Current second-line treatment options provide limited clinical benefit, highlighting the need for novel therapeutic strategies. Epidermal growth factor receptor (EGFR) is overexpressed in approximately 20-30% of gastric cancers and is associated with aggressive tumor biology and poor prognosis. Previous studies evaluating anti-EGFR monoclonal antibodies or tyrosine kinase inhibitors in unselected gastric cancer populations failed to demonstrate survival benefit, largely because of the lack of biomarker-based patient selection and the limited efficacy of conventional EGFR-targeted agents. Becotatug vedotin (MRG003), an EGFR-directed antibody-drug conjugate (ADC) carrying monomethyl auristatin E (MMAE), exerts potent cytotoxic activity through EGFR-mediated internalization and intracellular payload release. In addition, MMAE-containing ADCs may induce immunogenic cell death and remodel the tumor immune microenvironment, providing a strong biological rationale for combination with programmed cell death protein-1 (PD-1) blockade. Pucotenlimab is a humanized anti-PD-1 monoclonal antibody with demonstrated antitumor activity and favorable safety in multiple solid tumors. This is a prospective, single-center, open-label, single-arm phase II investigator-initiated trial designed to evaluate the efficacy and safety of becotatug vedotin in combination with pucotenlimab as second-line treatment in patients with EGFR-positive unresectable locally advanced, recurrent, or metastatic gastric or gastroesophageal junction adenocarcinoma who have progressed after standard first-line therapy. Approximately 28 patients will be enrolled. Participants will receive becotatug vedotin (2.0 mg/kg, intravenous infusion, every 3 weeks) plus pucotenlimab (200 mg, intravenous infusion, every 3 weeks) until disease progression, unacceptable toxicity, withdrawal of consent, or investigator decision. The primary endpoint is objective response rate (ORR) assessed according to RECIST version 1.1. Secondary endpoints include disease control rate (DCR), progression-free survival (PFS), overall survival (OS), duration of response (DoR), time to response (TTR), and safety. Exploratory analyses will evaluate the association between treatment outcomes and biomarkers including EGFR expression, PD-L1 expression, tumor mutational burden, microsatellite instability/mismatch repair status, and immune-related biomarkers, aiming to identify patients most likely to benefit from this combination therapy.

Digital Rehabilitation for Gastric Cancer Surgery After Neoadjuvant Therapy

The goal of this clinical trial is to investigate the effects of a perioperative multimodal rehabilitation program on the incidence of postoperative complications and perioperative clinical indexes including functional capacity, nutritional and psychological status in patients with gastric cancer undergoing neoadjuvant therapy. Besides the investigators also develop a smart phone based digital platform aiming to evaluate its effectiveness in improving patient adherence, compared with the conventional telephone supervision approach. The main questions it aims to answer are: * Can the perioperative multimodal rehabilitation program reduce postoperative complications in patients with gastric cancer undergoing neoadjuvant therapy? * Can the smart phone based digital platform improve patients' adherence compared to traditional telephone supervision? * Can the perioperative multimodal rehabilitation program improve the perioperative clinical indicators of patients with gastric cancer undergoing neoadjuvant therapy, including functional capacity, nutritional status and psychological condition? The investigators will compare the perioperative multimodal rehabilitation program with the standard treatment alone to determine whether this program has the effects mentioned above. Participants will follow the perioperative multimodal rehabilitation program from neoadjuvant therapy through to four weeks after discharge.

A Dose Optimization/Expansion Study of SAR445877 in Adult Chinese Participants With Advanced Gastric or Gastroesophageal Junction Cancer

This is a Phase 2, open-label, dose optimization/expansion study to assess the preliminary efficacy and safety of SAR445877 as a monotherapy for Chinese participants aged at least 18 years with advanced Gastric Cancer(GC)/Gastroesophageal Junction cancer (GEJ). Participants with advanced GC/GEJ who relapsed to at least 1 prior regimen which may or may not include an anti-PD1/PD-L1-based treatment depending on local standard of care, regardless combined positivity score (CPS) will be randomized in this study. In this study, SAR445877 will be assessed as a monotherapy in approximately 30 participants with advanced unresectable or metastatic GC or Siewert Type 2 and 3 GEJ, and for whom receiving the standard of care (SOC) is not in his or her best interest, or where no SOC is established. Human epidermal growth factor receptor 2 (HER2) positive cases will not be eligible unless they have progressed on a HER2 targeted therapy. Those participants should have received at least 1 prior line of anti-cancer treatment which may or may not include an anti-PD1/PD-L1-based treatment depending on local standard of care. Metastatic microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) cases are not eligible.

Comparison of Partial Stomach-Partitioning and Conventional Gastrojejunostomy for the Treatment of Gastric Outlet Obstruction in Advanced Gastric Cancer

The primary goal of clinical treatment is to relieve obstruction, restore oral feeding, improve nutritional status and improve quality of life in patients with advanced gastric cancer outflow tract obstruction. At present, the common surgical treatment for relieving obstruction is traditional gastrojejunostomy. Although the operation can relieve the obstruction, there are problems such as tumor-induced bleeding, anastomotic invasion, and high incidence of delayed gastric emptying after operation. Partitioned gastrojejunostomy effectively relieves obstruction by anastomosis of a part of the stomach to the jejunum, and isolates the tumor from the anastomosis, which is beneficial to food emptying and can reduce the risk of bleeding and anastomotic invasion. The safety and efficacy of these two procedures are still controversial, mainly because previous studies were retrospective studies or included a small sample size or enrolled patients with different pathological characteristics. The purpose of this study was to compare the safety and efficacy of separated and traditional gastrojejunostomy in the treatment of advanced gastric cancer outflow tract obstruction, and to provide the best choice for the treatment of advanced gastric cancer outflow tract obstruction.

It characterizes the oral, fecal and intratumoral microbiome of Colombian adults with advanced solid tumors (gastric, colorectal, breast, cervical and head-and-neck cancer) who receive first-line immunotherapy as standard of care, and compares them with healthy volunteers. Using multi-omics (HiFi metagenomics, 16S, tumor RNA-Seq and untargeted metabolomics), the study aims to identify microbial signatures associated with treatment response and survival, building the initial Colombian cohort of a Cancer Microbiome Atlas with Latin American projection.

Predicting Peripheral Neuropathy of Paclitaxel for Gastric Cancer

Although advances in chemotherapy have improved the prognosis of gastric cancer patients, many patients still suffer from adverse events. Therefore, it is necessary to establish personalized treatment by identifying patients at high risk for side effects. Although paclitaxel-based therapy is the standard second-line treatment, peripheral neuropathy is a troublesome adverse event. The purpose of this study is to establish a liquid biopsy assay to predict paclitaxel-induced peripheral neuropathy in gastric cancer patients.
