Fasting-mimicking diet test for ulcerative colitis
This study tests whether a “fasting-mimicking diet” can improve mild to moderate ulcerative colitis. You would follow the study diet plan and be monitored to see if symptoms and disease activity change.
Palo Alto, CaliforniaAges 18–70 - NCT03616041Recruiting
Capsule camera test for severe rectal bleeding
This trial tests a swallowable camera (capsule endoscopy) to look inside the gut in people with severe ongoing rectal bleeding. It may help doctors find the bleeding source when symptoms are serious and blood counts are dropping.

Skinfold fat measurement and survival in certain digestive cancers
This study looks at whether a simple measurement of fat under the skin (taken at the back of the upper arm) relates to how long people live. It includes adults newly diagnosed with pancreatic, bile duct, or gallbladder cancer who are starting treatment.
SeoulAges 18 years+ - NCT03643718Recruiting
Emergency surgery and trauma patient registry online
This trial is a web-based registry that collects information about people who need emergency surgical or non-surgical treatment for sudden (acute) problems. Your information can help doctors better understand and improve emergency care and decision-making.
PisaAges Any age - NCT03659448RecruitingPhase 3
Test drug that helps map colon and rectal cancer during surgery
This Phase 3 study tests SGM-101, a drug used during surgery to help doctors better outline primary, recurrent, and spread (metastatic) colorectal cancer. It may improve how completely tumors are identified and removed during an operation.
Duarte, CaliforniaAges 18 years+ - NCT03667170RecruitingPhase 2
Study drug for certain colon cancers with MSI-H or dMMR
This Phase 2 trial tests KN035 in people with advanced or spread-out tumors that have specific genetic markers (MSI-H or dMMR). If you qualify, the study team will look at how well the drug works and how it affects side effects in that group.
Beijing, Beijing MunicipalityAges 18 years+ - NCT03669874Recruiting
Endoscopic surgery for long-term reflux using a special system
This trial tests whether an endoscopic fundoplication procedure (a reflux surgery done through the scope) using the MUSE system can better control long-term reflux symptoms. It likely fits people with chronic reflux confirmed by testing who may be candidates for surgical treatment.
MilanAges 18–70 - NCT03670472Recruiting
Gene therapy for cystic fibrosis with specific CFTR mutations
This study looks at correcting “stop” mistakes (nonsense mutations) in the CFTR gene, which can cause cystic fibrosis. If your CFTR test shows the exact type of mutation the study needs, you may be able to take part.
AmiensAges 8 years+ - NCT03671252RecruitingPhase 3
Chemotherapy before surgery for rectal cancer vs chemo with radiation
This Phase 3 trial compares two treatment plans given before rectal surgery. It tests whether stronger chemotherapy alone works better than chemotherapy pills plus long-term radiation to improve outcomes for locally advanced rectal cancer.
Guangzhou, GuangdongAges 18–75 - NCT03681652Recruiting
Study of recovery outcomes after Crohn’s surgery in children
This study looks at outcomes after children with Crohn’s disease have part of the bowel removed (ileo-cecal resection). It may help doctors improve post-surgery care, especially for preventing flare-ups in the months after surgery.
Petah Tikva, IsraelAges 6–18 - NCT03685045Recruiting
Hepatitis C treatment support for people using opioid substitutes
This trial is studying hepatitis C treatment approaches for adults who have a history of injecting drugs, especially those who have injected recently or are on opioid substitution therapy. If you fit the background criteria, the study may offer a treatment pathway and extra support to help you get hepatitis C treated.
Canberra, Australian Capital TerritoryAges 18 years+ - NCT03686709Recruiting
Extra scan and blood testing with Y90 radioembolization
This study looks at how well Y90 “radioembolization” treatment delivers radiation and how much radiation reaches your body. If you can safely get extra PET/CT scans and blood tests around your treatment, you may be invited to participate.
Knoxville, TennesseeAges 18 years+ - NCT03699228Recruiting
Low-dose chest CT study for adults in China
This study is looking at people ages 30 to 90 who are willing to get a low-dose chest CT scan. It may help researchers improve how health data is collected and understood from scans.
Wuhu, AnhuiAges 30–90 - NCT03702309Recruiting
Banking and testing blood samples to study cancer
This study collects blood samples to “test and store” (bank) information that may help doctors understand cancer in the future. You might be able to join if you’re an adult with confirmed cancer or a higher-than-usual risk for cancer.
Toronto, OntarioAges 18 years+ - NCT03711110Recruiting
Heart-protection plan for older people with certain cancers
This trial looks at strategies to help prevent heart and blood-vessel problems in people over 65 who have certain cancers. It may help by monitoring and treating heart risks early to lower the chance of future cardiovascular events.
Santiago de Compostela, A CoruñaAges 65 years+ - NCT03711890Recruiting
Advanced imaging to detect early pancreatic cancer during surgery
This study tests a special high-resolution camera that can see tiny details during pancreatic surgery to help doctors detect early-stage pancreatic cancer or precancerous growths called IPMNs. The goal is to improve how well surgeons can identify and remove diseased tissue.
Columbus, OhioAges 18 years+ - NCT03712774Recruiting
Study of how chemoradiation affects quality of life
This observational study follows people with esophageal cancer to see how their quality of life changes after chemoradiation. It does not change your treatment, but it may help doctors better understand what to expect during and after therapy.
Munich, BavariaAges 18 years+ - NCT03715517Recruiting
Spinal anesthesia to improve recovery after liver surgery
This trial studies whether using spinal/epidural anesthesia during liver tumor removal surgery can help people recover better and with less pain. It compares this approach to standard general anesthesia care to see if recovery is smoother.
Winnipeg, ManitobaAges 18 years+ - NCT03716089Recruiting
Laparoscopic surgery for stomach GIST by tumor site
This trial studies whether doing laparoscopic surgery for stomach GISTs (gastrointestinal stromal tumors) works and is safe when the tumor is in a “favorable” versus “unfavorable” location. You might be eligible if your tumor is confirmed as GIST and doctors expect to remove it completely using keyhole surgery.
Fuzhou, FujianAges 18–75 - NCT03731442RecruitingPhase 3
Radiation plus chemotherapy for esophageal cancer that came back
This Phase 3 trial studies giving combined chemotherapy and radiation to treat esophageal cancer that has returned after earlier surgery and/or prior treatments. It may help control the cancer in the area where it comes back, especially when the surgical margins were not fully clear or the cancer is outside the original radiation field.
Beijing, Beijing MunicipalityAges 16–70 - NCT03731130Recruiting
Study on quality of life after rectal cancer treatment and surgery
This observational study follows people with rectal cancer who get radiation (with or without chemotherapy) before surgery. It aims to understand how these treatments affect quality of life after surgery.
Munich, BavariaAges 18 years+ - NCT03736863RecruitingPhase 2
Testing combinations of medicines for advanced throat cancer
This trial tests a combination of medicines to treat advanced esophageal squamous cell carcinoma (throat/esophagus cancer) that cannot be removed by surgery and has spread or come back. It is for people whose first treatment (chemotherapy or immunotherapy) did not work well or was not tolerated.
Zhengzhou, HenanAges 18–75 - NCT03740256RecruitingPhase 1
HER2-targeted oncolytic virus plus custom immune cells for solid cancers
This Phase 1 study tests a treatment plan that combines a virus designed to attack cancer with your own custom immune cells that target HER2. It aims to shrink advanced HER2-positive solid tumors (and make future options safer/more effective).
