127 Clinical Trials for Various Conditions
This is a multicenter, open-label, prospective Phase 1/2a study to assess safety and tolerability, establish dosimetry and to identify an optimal imaging dose (radioactivity and mass dose) and imaging time window of 64Cu-LNTH-1363S (64Cu Radiolabeled FAPi PET/CT Imaging Agent) and to compare its imaging biodistribution with FAP expression by immunohistochemistry (IHC) in patients with sarcomas or GIT cancers. The study will be conducted in 2 parts (Part 1 and Part 2).
A Phase 2 multi-center, open-label, single arm study of nab-sirolimus in patients with well-differentiated neuroendocrine tumors (NETs) of the gastrointestinal tract, lung, or pancreas who have not received prior treatment with mTOR inhibitors
This randomized Phase 3 open-label study will compare the efficacy of the T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif (ITIM) domain (TIGIT) monoclonal antibody domvanalimab, the anti programmed cell death protein 1 (PD-1) monoclonal antibody zimberelimab, and multiagent chemotherapy versus the anti PD-1 monoclonal antibody nivolumab and multiagent chemotherapy in the first-line treatment of participants with locally advanced unresectable or metastatic gastric, gastroesophageal junction (GEJ), and esophageal adenocarcinoma.
The purpose of this study is to evaluate the safety and preliminary clinical activity of treatment combinations with and without chemotherapy in participants with locally advanced unresectable or metastatic gastric, GEJ, and esophageal adenocarcinoma. Chemotherapy will consist of FOLFOX (oxaliplatin, leucovorin, fluorouracil).
The purpose of this study is to determine if it is possible to make and safely administer a 'personalized' cancer vaccine for people diagnosed with an upper gastrointestinal tract cancer.
The purpose of this prospective registry is to assess long-term data on efficacy, safety and clinical outcome of endoscopic placement of suture(s) and approximation of soft tissue within the gastrointestinal tract for various GI tract disorders. Currently, lack enough data evaluate and verify technical feasibility, clinical success and safety of endoscopic suturing in specific gastrointestinal disorders.1-16 Evaluation of these factors would help us compare them to conventional treatment modalities; and consequently help us identify appropriate treatment techniques and improve clinical management of patients.
After removing large polyps from the gastrointestinal tract, gastroenterologists close the new defect with devices to prevent complications like bleeding or the development of a leak. Commonly, this is done with a device called Overstitch, which allows the gastroenterologist to stitch the defect with an endoscope. A new device called X-tack has been developed to simplify endoscopic stitching. In this study, the new X-tack device will be compared to Overstitch when closing defects in the gastrointestinal tract. The two devices will be compared to see how long it takes to close a defect, as well as if there are any differences in complications like bleeding or infection.
Blenderized diets consist of a wide range of table foods such as fruits, vegetables, meat and legumes, pureed in a blender and administered via gastrostomy tube. In a recent study, the investigators reported that children receiving blenderized feeds via gastrostomy had fewer total admissions and respiratory admissions, total emergency room visits, and improved gastrointestinal symptom scores compared to those fed formula. The goal of this project is to understand how these diets affect gastroesophageal reflux burden.
The main purpose of this research study is to determine if exercise improve or worsen cachexia.
This clinical trial will compare stool and oral microbiome composition between infants fed breast milk or one of two infant formulas for a 60 day feeding period.
This randomized, open-label, clinical study aims to explore the safety and tolerability of KB109, a novel glycan, versus an observational control group on the gut microbiome in subjects whose gastrointestinal tracts are colonized with multiple drug-resistant organisms.
As explained in detail in a recently published hypothesis article (Hladik F. A new hypothesis on HIV cure. F1000Research, 4:77 (2015)), the investigators hypothesize that NRTI drugs may reduce the likelihood of HIV eradication by promoting the survival of cells with integrated provirus. In this study, the investigators will test whether daily oral use of two NTRI drugs, tenofovir and emtricitabine (Truvada Pill), induces changes in the upper and lower gut mucosa that are congruent with supporting this hypothesis.
This randomized phase II trial studies how well temozolomide and capecitabine work compared to standard treatment with cisplatin or carboplatin and etoposide in treating patients with neuroendocrine carcinoma of the gastrointestinal tract or pancreas that has spread to other parts of the body (metastatic) or cannot be removed by surgery. Drugs used in chemotherapy, such as temozolomide, capecitabine, cisplatin, carboplatin and etoposide, 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. Certain types of neuroendocrine carcinomas may respond better to treatments other than the current standard treatment of cisplatin and etoposide. It is not yet known whether temozolomide and capecitabine may work better than cisplatin or carboplatin and etoposide in treating patients with this type of neuroendocrine carcinoma, called non-small cell neuroendocrine carcinoma.
This phase II trial studies how well methylprednisolone sodium succinate works in treating patients with graft-versus-host disease (GVHD) of the gastrointestinal tract that has begun within 100 days of transplant (acute GVHD). Corticosteroids are a type of drug that reduces inflammation. Giving corticosteroid drugs, such as methylprednisolone sodium succinate, directly into the arteries of the gastrointestinal tract may help treat inflammation caused by GVHD. Giving methylprednisolone sodium succinate in addition to standard treatments may be more effective in treating GVHD.
The purpose of this study is to determine whether Alvimopan (Entereg) in ventral hernia surgery patients is associated with accelerated gastrointestinal recovery and reduced length of hospital stay compared to placebo controls.
Background: - Neuroendocrine tumors (NETs) come from cells of the hormonal and nervous systems. Some people have surgery to shrink the tumor. Sometimes the tumors come back. Researchers think that treatment with drugs based on knowing the defective gene might give better results. Objective: - To see if drugs selected based on the defective gene result in better tumor response. The drugs are Sunitinib and Everolimus. Eligibility: - People age 18 and older with an advanced low- or intermediate-grade gastrointestinal or pancreatic neuroendocrine tumor. Design: * Participants will be screened with: * Medical history * Physical exam * Scans * Blood, urine, and lab tests * The study team will see if participants should have surgery. * If yes, participants will: * Sign a separate consent * Have computed tomography (CT) scan before and after surgery * Have as much of the tumor removed as possible. A small piece will be tested for mutation type. * If no, participants will have a small piece of tumor removed for the testing. * If the surgery might cure them, the participant will leave the study. The other participants will be assigned to take either Sunitinib or Everolimus. * Participants will take their drug by mouth once a day. They will keep a medicine diary. Some will keep track of their blood pressure at least weekly. * Screening tests may be repeated at study visits. Participants also may have their heart evaluated. * About 30 days after the last day of their study drug, participants will have a follow-up visit that repeats the screening tests. * Participants will be contacted every 3 months after this visit.
This is a Phase IV, open label, observational study to compare the gastrointestinal tissue concentrations, inflammatory response, and viral replication of two integrase-inhibitors, raltegravir and dolutegravir, in HIV-infected volunteers who are virologically suppressed in blood plasma. The study will be comprised of 20 HIV-infected volunteers who will be enrolled equally into two groups. Group A will consist of 10 subjects receiving an antiretroviral regimen of tenofovir, emtricitabine, and raltegravir, and Group B will consist of 10 subjects receiving an antiretroviral regimen of tenofovir, emtricitabine, and dolutegravir. Participants will provide small pieces of tissue, or biopsies, which will be taken from three distinct locations of the large intestine during a colonoscopy procedure. These biopsies will be used to measure the amount of raltegravir or dolutegravir, HIV virus, and inflammatory markers present in the gastrointestinal tract.
The purpose of this prospective registry is to assess long term data on efficacy, safety and clinical outcome of endoscopic placement of suture(s) and approximation of soft tissue within the Gastrointestinal tract for various GI tract disorders. The registry will evaluate technical feasibility, clinical outcome, safety profile and overall clinical management through medical chart review. The procedures the investigators are evaluating are all clinically indicated and will not be prescribed to someone to participate in this research study.
The particle size of the active ingredient may impact dissolution rate in the gastro intestinal tract and hence the amount of drug available for absorption. Similarly, differences in the percentage of the excipients used in the formulated capsules may affect dissolution rate. The purpose of this study is to estimate the effect that particle size and percentage of excipients could have in drug absorption, which will improve the manufacturing process of the formulated capsules.
The purpose of this study is to determine if lubiprostone may change the rate of movement of food and activities in the stomach and intestines in subjects whose gastrointestinal (GI) tract is slower due to constipation. To be able to measure the time difference in the duration of transit of the FDA approved SmartPill capsule in all segments of gastrointestinal (GI) tract before and after exposure to lubiprostone. The investigators anticipate to capture the possibility to reduce/eliminate the small intestinal bacterial overgrowth in chronically constipated patients after administration of study drug- lubiprostone.
The goal of the project is to determine whether confocal endomicroscopy can be used to identify and discriminate among dysplastic, neoplastic, and nonneoplastic tissue, as compared with histologic specimens as a reference. The project will evaluate those at risk for or with known Barrett's esophagus, and those with known or suspected biliary strictures. It is our hypothesis that we will be able to identify between neoplastic and nonneoplastic tissue.
Standard white light endoscopy involves the passage of a thin, flexible camera into the colon from the anus. Although standard white light endoscopy can detect most polyps and precancerous areas in the gastrointestinal tract and colon, many studies have shown that even the most experienced doctors, under optimal conditions, can miss up to 15-25% of precancerous areas. Thus, there remains a clear need to develop new methods of improving standard white light endoscopy. We are investigating whether indocyanine green (ICG) can serve to highlight areas which are precancerous when the colon is visualized with a special cameral which shines fluorescent light. Information from other studies suggests that this ICG agent may help to visualize blood vessels flowing to precancerous areas in the colon. We are looking at the ability of ICG, in combination with an endoscope which shines fluorescent light, to visualize precancerous areas in the colon.
Doctors at Memorial Sloan Kettering Cancer Center and at other institutions study normal and cancer cells. To study these cells we need to have human tissue, body fluids, and blood. The patient will be having or have had a procedure to remove tissue. The doctors would like to use some of this tissue. The doctors will use it for laboratory studies on the causes, prevention, diagnosis and treatment of sarcoma, gastrointestinal or other intra-abdominal cancers. They will only use extra tissue left over after all needed testing has been done. They would also like to study components of the immune blood cells and blood serum (the liquid portion of the blood). In some patients they will take a blood sample before the tissue or body fluid is removed, usually at the same time that other routine pre-procedure blood tests are drawn. If thet need more blood, it will be drawn when the patient is seeing the doctor anyway. We will not draw more than 50cc (4-5 tablespoons) at any one time. With the patient's permission, thet may also send a small portion of the blood and/or a sample of the tissue to a repository at the National Cancer Institute. This will be used to identify special proteins in the blood or tissue that may be useful for diagnosing cancer. Information about the treatment and the response to treatment may be linked to the tissue specimens obtained. This information may be important for the research studies that will be done on the tissue, body fluid and blood specimens. All of this information will be kept in strictest confidence; they will use it only for biomedical research. The patient's name will not be used in any report.
Optical coherence tomography (OCT) is a non-invasive imaging technique that uses light to create pictures of living tissues and has been successfully used to generate high resolution cross-sectional images of tissue in the human eye and skin. OCT systems are now commercially available for eye and skin use, and several clinical reports on the use of OCT in the gastrointestinal tract have been published as well. The purpose of this study is to develop a high-speed noninvasive OCT probe which can be placed through an endoscope for the early diagnosis of pre-cancerous and cancerous lesions in the gastrointestinal tract. This is a pilot clinical research study that is designed to advance OCT technology, which may in the future be able to replace or augment endoscopic biopsies.
The purpose of this study is to determine if Chlamydial infections persist in the rectum of females who have had a sexually transmitted infection of Chlamydia.
Primary Objective: 1. Assess the clinical activity defined by response rate of irinotecan and cisplatin in untreated patients with metastatic or unresectable high grade neuroendocrine carcinoma of the gastrointestinal tract. Secondary Objective: 1. To assess the safety profile of irinotecan and cisplatin in untreated patients with metastatic or unresectable high grade neuroendocrine carcinoma of the gastrointestinal tract.
RATIONALE: Beclomethasone may be effective in treating patients who have graft-versus-host disease of the gastrointestinal tract. PURPOSE: Compassionate use of beclomethasone in treating patients who have graft-versus-host disease of the gastrointestinal tract that has not responded to previous therapy.
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Interferon alfa may interfere with the growth of cancer cells. Colony-stimulating factors such as filgrastim may increase the number of immune cells found in bone marrow or peripheral blood and may help a person recover from the side effects of chemotherapy. Combining chemotherapy with interferon alfa may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of combining chemotherapy and interferon alfa followed by filgrastim in treating patients who have gastrointestinal tract cancer.
RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. PURPOSE: Randomized phase II trial to compare the effectiveness of two different vaccines in treating patients who have cancer of the gastrointestinal tract.
This protocol offers diagnosis and standard medical treatment for various parasitic gastrointestinal infections. Gastrointestinal parasites are either worms (helminths) or one-celled animals called protozoans which live in the human intestines. Often, parasitic infections do not cause illness. In these cases, drug treatment is not indicated, because treatment can have adverse side effects. Patients will be examined for their immune responses, correlation between the number of parasites and disease, and other studies. Individuals with known or suspected parasitic diseases of the gastrointestinal tract, including amebiasis, giardiasis, hookworm, strongyloidiasis, trichuriasis, pinworm, tapeworm, trichinosis, clonorchis, opisthorchis, coccidiosis, paragonimiasis, and echinococcus may be eligible for this study. Patient evaluations may include blood and urine tests, stool examination, X-rays, ultrasound studies and, uncommonly, duodenal aspiration for examination of fluid from the duodenum (first part of the small intestine). Other tests may be required, depending on the parasite and disease. Direct examination of the tissues of the intestines may be required to rule out certain infections. Research procedures include collection of stool, blood and duodenal fluid when the diagnosis has been established and these procedures are not required for medical care. Patients with strongyloidiasis may also be given a diagnostic skin test similar to skin tests for tuberculosis and allergies. Research procedures on children will be limited to collection of stool, urine and blood. No more than 7 milliliters (1 1/2 teaspoons) per kilogram (2.2 pounds) body weight of blood will be collected in children over a 6-week period. In adults no more than 30 tablespoons of blood will be collected in a 6-week period. Parasites may fail to respond to treatment. In these cases, it may be necessary to grow the parasite in the laboratory in order to test treatments in the test tube. Patients who do not respond to standard medications and dosing may need different doses of drugs or drugs or combinations of drugs used in the United States for other medical problems. If these medications or doses are used, patients will be informed of their possible side effects.
