Surgery comparison for advanced stomach cancer after initial surgery
This trial studies whether removing all of the fatty lining (omentum) or only part of it during surgery leads to better outcomes in people with advanced stomach cancer. It also checks that participants can safely have the same stomach-cancer chemotherapy plan after surgery.
Tianjin, Tianjin MunicipalityAges 18–70 - NCT04617184Recruiting
Join an inflammatory bowel disease registry and sample bank
This study asks people with known or suspected inflammatory bowel disease to enroll in a registry and biorepository. It helps researchers better understand the condition using health information and stored biological samples.
Austin, TexasAges 18–100 - NCT04908566RecruitingPhase 2
PD-1 immunotherapy plus chemotherapy before and after gastric surgery
This trial studies whether adding a PD-1 immune therapy to chemotherapy around the time of surgery can improve outcomes for people with locally advanced stomach or stomach–esophagus junction cancer. It aims to better control the cancer before and reduce the chance it comes back after surgery.
Tianjin, Tianjin MunicipalityAges 18–75 - NCT03569826Recruiting
Study for primary biliary cholangitis and autoimmune hepatitis
This study is for people diagnosed with primary biliary cholangitis or autoimmune hepatitis. It aims to learn more about these autoimmune liver conditions and may help guide better care in the future.
Calgary, AlbertaAges 18 years+ - NCT03787056Recruiting
Blood test marker study in many cancer types
This study measures a blood marker called progastrin (at diagnosis and during treatment) to see how well it predicts response or outcomes. It may help doctors choose or monitor treatment more precisely for several cancer types.
BronAges 18 years+ - NCT04965545Recruiting
Tests for diagnosing Wilson disease using special lab findings
This trial is for people who already have a genetic diagnosis of Wilson disease. It looks at whether specific lab tests and a physical eye finding can help confirm and support the diagnosis.
Hangzhou, ZhejiangAges 6–65 - NCT04965558Recruiting
Study of outcomes in genetic Wilson disease patients
This study looks at the health features and long-term outcomes in people with Wilson disease who have a genetic diagnosis. It may help doctors understand what to expect over time for different patients.
Hangzhou, ZhejiangAges 6–65 - NCT04022109Recruiting
Check gastric cancer using breath chemical signals
This study looks at chemical signals in your breath to help screen for or understand gastric (stomach) cancer. It may help doctors improve earlier detection, or better sort out who may need further tests.
São PauloAges 18 years+ - NCT02073500Recruiting
Study of treatments and models for cancer in the belly lining
This study looks at how cancers that spread along the belly lining (“peritoneal surface malignancies”) behave and how different treatment strategies may work. It may help improve how doctors select and test treatments for people who are candidates for CRS-HIPEC, a specific cancer surgery approach.
OsloAges 18 years+ - NCT03613545RecruitingPhase 2/Phase 3
Fecal transplant to treat irritable bowel syndrome
This study tests whether transferring stool bacteria from a healthy donor (fecal microbiota transplantation) can improve symptoms of irritable bowel syndrome (IBS). It may help by changing the gut bacteria that can influence digestion and gut discomfort.
Guangzhou, GuangdongAges 18–75 - NCT04989985RecruitingPhase 2
SOX chemotherapy plus immunotherapy for junction stomach-esophagus cancer
This trial studies whether adding an immunotherapy drug (sintilimab) to standard chemotherapy (S-1 and oxaliplatin) can better treat locally advanced cancer at the junction of the esophagus and stomach. It may help shrink the tumor and control the cancer before or around surgery.
Guangzhou, GuangdongAges 18–75 - NCT04997837RecruitingPhase 3
Adjuvant chemo with or without PD-1 for stomach cancer after surgery
This Phase 3 trial studies whether adding an immune medicine called PD-1 (given as an “inhibitor”) to standard chemotherapy and chemoradiation after stomach/GEJ cancer surgery can lower the risk of cancer coming back. You may qualify if you’ve had surgery removing the tumor and lymph nodes showed higher-risk disease.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT05035147RecruitingPhase 4
Albumin-bound paclitaxel plus gemcitabine for advanced pancreatic cancer
This trial studies a chemotherapy combination (albumin-bound paclitaxel and gemcitabine) as first treatment for pancreatic cancer that cannot be removed by surgery. It aims to improve outcomes by testing how well this treatment works in people with locally advanced or metastatic disease.
Tianjin, Tianjin MunicipalityAges 18 years+ - NCT05002166Recruiting
Study of children with inflammatory bowel disease risks
This study looks at the typical features and risk factors in children diagnosed with inflammatory bowel disease (IBD). It may help families understand what affects IBD in kids, even if it is not testing a new treatment.
AsyutAges Up to 18 years - NCT05010863Recruiting
Test and develop a stomach cancer detection kit
This study looks for marker signals from stomach cancer tissue to improve a detection kit. You may be asked to provide tissue samples, especially if you have a new stomach cancer diagnosis and have not had anti-cancer treatment yet.
Wenzhou, ZhejiangAges Any age - NCT05099432Recruiting
CARMA technique after removing up to two colon polyps
This study tests a specific approach (the CARMA technique) for colon polyp treatment after doctors remove polyps during colonoscopy. It may help reduce future problems at the polyp site, but only certain polyp types and follow-up plans qualify.
Woolloongabba, QueenslandAges 16 years+ - NCT04455932Recruiting
Test shorter MRI versus ultrasound for liver cancer screening
This study compares a shorter, non-contrast MRI and ultrasound to monitor for liver cancer in people with cirrhosis whose ultrasound images aren’t clear enough. It aims to see which method works better and may help you get safer, more reliable follow-up.
Camperdown, New South WalesAges 20–85 - NCT05055635RecruitingPhase 2
Proton radiation for anal cancer that came back after prior treatment
This trial studies a focused type of proton radiation (“pencil beam”) to treat anal cancer that has returned after you previously had radiation. It may help by aiming treatment more precisely and giving another chance at cure when doctors think it can still be treated.
Aarhus N, AarhusAges 18 years+ - NCT04109755RecruitingPhase 2
Pembrolizumab plus radiation before surgery for rectal cancer
This trial tests whether giving pembrolizumab (an immunotherapy medicine) together with short-course radiation before surgery helps people with localized rectal cancer. It is mainly for tumors that are microsatellite stable (MSS).
GenevaAges 18 years+ - NCT04393519Recruiting
Program to monitor you after TIPS with noninvasive checks
This trial looks at a follow-up and monitoring program after TIPS (a procedure to improve blood flow in the liver). It is meant to make sure the TIPS is working and to guide follow-up without relying on invasive testing when possible.
BonnAges 18–100 - NCT03717792Recruiting
Check how doctors follow up vascular liver disease
This study focuses on people who have vascular liver disease and aims to evaluate follow-up care and non-invasive ways to assess it. It may help improve how safely and accurately doctors monitor your liver without invasive procedures.
BonnAges 18–100 - NCT05066594Recruiting
Registry for a procedure to treat long-term reflux
This is an observational study (no experimental treatment) that follows people who choose a specific procedure called transoral incisionless fundoplication (TIF) with the EsophyX device for long-term acid reflux. It aims to track outcomes for up to 5 years at San Raffaele Hospital.
MilanAges 18–80 - NCT01277419Recruiting
Study of new cases of several spine, joint, and eye diseases
This study enrolls people who have recently been diagnosed with certain inflammatory conditions affecting the spine, joints, or the eye. Researchers are looking to better understand how these illnesses start and how they may be linked, which could help guide future care.
BerlinAges Any age - NCT04933669RecruitingPhase 2
Pre-surgery imatinib for high-risk stomach or gut GIST
This trial studies whether taking imatinib before surgery can shrink or control high-risk gastrointestinal stromal tumors (GIST). If you qualify, you would receive imatinib as “neoadjuvant” (before the operation) and then move on to planned surgery.
