The Vanguard Study: Testing a New Way to Screen for Cancer
The Vanguard Study is a feasibility study to explore several aspects of evaluating multi-cancer detection (MCD) tests in a future definitive randomized controlled trial. An MCD test measures markers in the blood in order to screen for multiple cancers simultaneously. There is a need to understand how MCDs may work as cancer screening tools. The goal of cancer screening is to reduce the burden of cancer by identifying cancers before they show symptoms or signs, when treatment is likely to be most effective. In this study, adults aged 45-75 without cancer will be randomly assigned to one of 3 groups: 2 separate MCD test groups or a control group. These two MCD tests will not be compared to each other but will be compared to cancers detected in the control group. This study will provide early information on how well MCD tests perform as cancer screening tools. It will also help researchers understand how patients and their doctors make decisions about their care when the MCD test result comes back as normal (negative) or abnormal (positive).

Targeted Therapy Directed by Genetic Testing in Treating Patients With Advanced Refractory Solid Tumors, Lymphomas, or Multiple Myeloma (The MATCH Screening Trial)
This phase II MATCH screening and multi-sub-trial studies how well treatment that is directed by genetic testing works in patients with solid tumors, lymphomas, or multiple myelomas that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and does not respond to treatment (refractory). Patients must have progressed following at least one line of standard treatment or for which no agreed upon treatment approach exists. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with genetic abnormalities (such as mutations, amplifications, or translocations) may benefit more from treatment which targets their tumor's particular genetic abnormality. Identifying these genetic abnormalities first may help doctors plan better treatment for patients with solid tumors, lymphomas, or multiple myeloma.

A Study to Test Different Doses of BI 765049 in People With Advanced Cancer of the Colon, Rectum, Stomach, or Pancreas
This study is open to adults with advanced cancer of the colon, rectum, stomach, or pancreas, that is the cancer cannot be removed by surgery or has spread. People can take part in this study if their previous treatment was not successful, or no other treatment exists. The study aims to find the highest dose for the study medicine called BI 765049 that people with advanced cancer can tolerate. Another purpose is to find the most suitable dose and best way of administration of BI 765049 for further clinical development. BI 765049 may help the immune system fight cancer. Participants receive BI 765049 at least once every 3 weeks. Participants may continue to get BI 765049 treatment as long as they benefit from treatment and can tolerate it. Participants in this study also get additional medication before and after treatment with BI 765049 for better tolerability. If participants take this medication at home, they have daily phone visits. Participants regularly visit the study site. The study visits include several overnight stays at the hospital. At the visits, study doctors check participants' health, take necessary laboratory tests, and note any unwanted effects. Unwanted effects are any health problems that the doctors think were caused by the study medicine or treatment. To find the highest dose of BI 765049 that participants can tolerate, researchers look at the number of participants with certain severe health problems. These are severe health problems that happen within the time from when a person first receives the intended target dose, until one week after they receive it for the second time.

Risk Assessment Evaluation for Identifying Participants at High Risk for Stomach Cancer
This clinical trial evaluates the usefulness of various risk assessment tests, including Helicobacter pylori (H. pylori) breath testing, questionnaires, and endoscopies for identifying participants at high risk for stomach cancer. H. pylori is a bacteria that causes stomach inflammation and ulcers in the stomach. People with H. pylori infections may be more likely to develop cancer in the stomach. H. pylori breath testing can help identify the presence of H. pylori infection in a participant and help identify if the participant may be at a higher risk of developing stomach cancer. An endoscopy uses a thin, flexible lighted tube that is inserted inside the esophagus, stomach, and first part of the small intestine. This allows the doctor to see and look for abnormal areas that may need to be biopsied. Risk assessment including H. pylori evaluation, questionnaires, and endoscopies may help identify participants at high risk for stomach cancer and may be a useful screening tool for earlier stomach cancer diagnosis.

PET-imaging of Two Vartumabs in Patients With Solid Tumors
VARTUTRACE is a first-in-human PET/CT molecular imaging study in patients with solid tumors. This study will investigate the biodistribution and pharmacology of two antibody fragments binding oncofetal Chondroitin Sulfate (CS). Oncofetal CS are tumor-specific carbohydrate motifs present in proteoglycans and identified by VAR2 Pharmaceuticals as expressed during fetal development. Oncofetal CS reappears in the vast majority of cancers while remaining largely absent from normal tissues. VAR2 Pharmaceuticals recently developed antibodies specific for oncofetal CS. VARTUTRACE uses two of these as radiolabeled antibody fragments to study biodistribution, tumor accumulation, pharmacodynamics and clearance pathways in a diverse patient population.

Determining the Biodistribution of an Imaging Tracer (68Ga-FAPi-46) in Patients With Solid Tumors or Hematologic Cancers
This phase I trial is evaluating a new imaging tracer (68Ga-FAPi-46) with positron emission tomography (PET)/computed tomography (CT) to determine where and to which degree the tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues (the biodistribution) in patients with solid tumors or hematologic (blood) cancers. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of tracer, in the case of this research, 68Ga-FAPi-46. Because some cancers take up 68Ga-FAPi-46, it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs and potential inflammatory tissue where it occurs in a patient's body. Combining a PET scan with a CT scan can help make the image easier to interpret. PET/CT scans are hybrid scanners that combine both modalities into a single scan during the same examination.

Experimental PET Imaging Scans Before Cancer Surgery to Study the Amount of PET Tracer Accumulated in Normal and Cancer Tissues
This phase I trial studies a new imaging technique called FAPi PET/CT to determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulate in normal and cancer tissues in patients with non-prostate cancer. The research team also want to know whether what they see on PET/CT images represents the tumor tissue being excised from the patient's body. The research team is also interested to investigate another new imaging technique called PSMA PET/CT. Participants will be invited to undergo another PET/CT scan, with the PSMA tracer (68Ga-PSMA-11). This is not required but just an option for volunteer patients. Patients who have not received an 18F-FDG PET/CT within one month of enrollment will also undergo an FDG PET/CT scan. The PET/CT scanner combines the PET and the CT scanners into a single device. This device combines the anatomic (body structure) information provided by the CT scan with the metabolic information obtained from the PET scan. PET is an established imaging technique that utilizes small amounts of radioactivity attached to very minimal amounts of, in the case of this research, 68Ga-PSMA-11 and 68Ga-FAPi, and 18F-FDG (if applicable). Because some cancers take up 68Ga-PSMA-11 and/or 68Ga-FAPi it can be seen with PET. CT utilizes x-rays that traverse the body from the outside. CT images provide an exact outline of organs where it occurs in patient's body. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors. The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers. PSMA stands for Prostate Specific Membrane Antigen. This name is incorrect as PSMA is also found in many other cancers. The function of PSMA is not well understood but imaging studies have shown that PSMA can be detected with PET in many non-prostate cancers. Imaging FAP with PET/CT may in the future provide additional information about various cancers.

Detection of Upper Gastrointestinal Tumour Depth and Demarcation Using Systemic Administration of Indocyanine Green During Endoscopic Submucosal Dissection
Endoscopic submucosal dissection (ESD) is a relatively new technique to treat superficial cancers in the upper gastrointestinal (GI) tract. Previous studies reported high en bloc resection rates (95%-97%). However, R0 resection rates (84.5%) suggest that the tumour is not radically removed in all cases, resulting in a risk of tumour recurrence. One of the key challenges is the limited accuracy in determining the depth of cancer invasion. To reduce the risk of tumour recurrence, the endoscopist would greatly benefit from proper and complete visualization of the tumour margin and depth during ESD. Several studies have shown that near-infrared quantified fluorescence molecular endoscopy (qFME) could serve as a red flag detection method and might be a useful imaging tool for tumour demarcation in the upper GI tract. The aim of this study is to evaluate the feasibility of ICG-enhanced near-infrared qFME to determine tumour demarcation and tumour depth in upper GI tumours (e.g. superficial esophageal and/or gastric adenocarcinoma (T1)) during ESD.

XNW27011 Study of Advanced Solid Tumor Subjects Who Failed Standard Therapies.
This is a global, multi-center, open-label, Phase I/II first-in-human study of XNW27011 monotherapy as an investigational product (IP) in patients with locally advanced and/or metastatic solid tumors who have failed or are intolerant to standard therapies. XNW27011 is an antibody-drug conjugate (ADC) targeting Claudin 18.2 (CLDN18.2), a transmembrane protein important to tight junctions. The study consists of 2 parts: Part 1 is the dose-escalation phase (Phase I), and Part 2 is the does-expansion phase (Phase II). In phase I part of the study, approximately 42 patients with locally advanced and/or metastatic solid tumors will be enrolled, irrespective of CLDN18.2 expression. However, the most recently available tumor tissue specimen will be collected (if available) for a retrospective CLDN18.2 expression confirmation. In phase II part of the study, only patients with confirmed CLDN18.2 expression by IHC in the central laboratory will be enrolled.The phase II part of the study will consist of the following four groups,Up to three dose cohorts for each patient group are planned currently. Each dose cohort will include approximately 20 patients. Approximately 240 patients evaluable will be enrolled in Phase Ⅱ part of the study.

The Correlation Between Blood Concentration of Sintilimab and Efficacy and Adverse Reactions in Patients with Advanced Gastric Cancer
Compared with other anti-tumor drugs, immune checkpoint inhibitors (ICIs) have their own unique pharmacokinetics (PK) and pharmacodynamics (PD), and affect patient clinical outcomes. However, at present, the data on the PK and PD characteristics of ICIs in the Chinese population are still lacking, thus further clinical trials are needed to verify them. At the same time, a large proportion of patients have no response to ICIs or the efficacy is poor, and even bring greater side effects, so it is particularly important to find effective biomarkers to predict the efficacy and adverse reactions of patients with ICIs treatment.The purpose of this study is to explore the correlation between blood concentration of Sintilimab and related predictors with efficacy and adverse reactions in patients with advanced gastric cancer so as to provide clinical reference for individualized treatment of patients with gastric cancer.
