Melbourne, VictoriaAges 18 years+ - NCT04782557Recruiting
Ultrasound-guided blood sampling to track cancer DNA
This study uses an ultrasound-guided procedure to collect blood and check for cancer DNA (small bits of tumor material in the bloodstream). It aims to see whether this method can better track how gastric, pancreatic, or colorectal cancer responds to treatment.
Hong KongAges Any age - NCT04613570Recruiting
Follow-up endoscopy plan for early stomach changes
This study looks at how often and how intensely to do follow-up stomach camera exams (endoscopy) with small biopsies for people at risk of stomach cancer. It may help personalize your follow-up schedule based on your specific stomach findings.
PortoAges 45 years+ - NCT05307367Recruiting
Study exercise and body muscle changes in advanced lung cancer
This study looks at why cancer can cause loss of muscle in people with advanced non–small cell lung cancer, and whether exercise can improve or explain those muscle changes. You may be asked to do physical testing and answer questionnaires while receiving standard palliative cancer treatment.
Copenhagen, DKAges 18–100 - NCT05408897Recruiting
Blood test to predict risk after surgery for high-risk GIST
This study uses a “liquid biopsy” blood test to look for leftover cancer signals after surgery. It aims to predict how well treatment will work and how likely the cancer is to come back in people with high-risk GIST.
Beijing, Beijing MunicipalityAges Any age - NCT03848962Recruiting
Share leftover or collected samples for research
This study helps collect and share human samples (like blood or other specimens) so researchers can do new studies. It’s mainly about providing samples for research use, not testing a treatment on you.
Huntsville, AlabamaAges 1 month–89 years - NCT05751733Recruiting
Apatinib versus standard drug for advanced GIST after imatinib
This trial studies whether apatinib works better than the usual second-line targeted tablet for advanced gastrointestinal stromal tumor (GIST) after imatinib (or avatinib) no longer works. It may help people whose cancer has grown despite treatment or who couldn’t tolerate it.
Changsha, HunanAges 18 years+ - NCT05247112Recruiting
Tracking antibiotic resistance in H. pylori infections in Korea
This study looks at how resistant H. pylori (a stomach germ) is to different antibiotics in Korea. It uses stomach endoscopy samples to test which antibiotics may or may not work, helping guide future treatment choices.
Seongnam-si, Gyeonggi-doAges Any age - NCT05996458Recruiting
Combined screening for stomach and colon cancers
This study aims to find a better way to screen for stomach and colon cancers. You will be asked to provide a stool sample, and possibly have an endoscopy (a camera test), to see if combined screening can catch cancer early.
Zhaoqing, GuangzhouAges 45–70 - NCT06104241RecruitingEarly Phase 1
Cell therapy for advanced digestive cancers
This trial tests a new cell therapy called BGT007 for people with advanced cancers of the digestive system (esophagus, stomach, pancreas, or colon) that have not responded to standard treatments. The therapy uses your own immune cells, modified to target a protein on your cancer cells.
