High-dose radiation treatment for hard-to-remove liver tumors
This study uses a form of targeted radiation placed inside/near the liver to treat liver tumors that can’t be surgically removed. It’s meant to shrink or control tumors, especially when they sit near blood vessels or other sensitive organs.
Houston, TexasAges 19 years+ - NCT05053945Recruiting
Track stomach changes after H. pylori infection
This study follows adults with past or current H. pylori infection to better understand stomach lining changes such as atrophic gastritis and intestinal metaplasia, and to monitor for possible progression. It may help by improving how doctors track risk over time and use stored tissue samples to learn more.
Hong KongAges 18 years+ - 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+ - NCT05055648RecruitingPhase 3
Proton vs photon radiation for esophageal cancer before surgery
This trial compares proton therapy and standard photon therapy given before surgery for esophageal (or stomach–esophagus) cancer. It aims to see which radiation approach works better and is safer as part of a combined treatment plan.
LeuvenAges 18 years+ - NCT05059444Recruiting
Blood test study to watch for cancer coming back
This study looks at whether blood tests can detect signs that cancer may return after curative-intent treatment. You would have blood drawn around your usual follow-up visits for up to 5 years, and your de-identified health data would be shared with study investigators.
Birmingham, AlabamaAges 18 years+ - NCT05060289Recruiting
Predicting drug-related liver injury using blood tests and expert review
This trial builds a prediction model to identify drug-related liver injury (DILI) by looking at your blood test patterns, timing, and expert diagnosis. It may help improve how doctors recognize this condition earlier and more accurately.
Beijing, Beijing MunicipalityAges 18 years+ - NCT05061680Recruiting
Balloon treatment for large bile duct stones
This trial looks at a procedure that uses a large balloon to help remove big stones from the bile duct. It may help people with large common bile duct stones who are safe for this approach.
HelsinkiAges 18–95 - NCT05061576Recruiting
At-home exercise program for people with liver scarring
This study tests an at-home, guided physical exercise plan for people with liver cirrhosis. It may help improve strength and day-to-day functioning while monitoring safety.
StockholmAges 18 years+ - NCT05065957RecruitingPhase 2/Phase 3
Study of two oral chemo medicines for advanced bile duct cancer
This trial tests a combination of two oral chemotherapy medicines (D07001 softgel plus Xeloda/TS-1) in people with advanced bile duct tract cancer that can’t be removed by surgery. It’s for situations where first-line gemcitabine plus cisplatin chemotherapy no longer worked.
Kaohsiung CityAges 18 years+ - NCT05065801RecruitingPhase 2
New metastatic pancreatic cancer: targeted chemo before FOLFIRINOX
This trial tests whether adding Gembrax (a combination that includes gemcitabine and nab-paclitaxel) before standard FOLFIRINOX works better than FOLFIRINOX alone in people with pancreatic cancer that has already spread. It looks at whether this “step-up first” approach improves results and is still tolerable.
Grenoble, Auvergne-Rhône-AlpesAges 18–75 - NCT05066139Recruiting
Study of older adults with digestive cancer
This study checks how well different care plans work for people age 75 and older who have digestive cancer and are about to start chemotherapy or targeted therapy. The goal is to improve treatment support and outcomes by doing a detailed, multidisciplinary evaluation.
StrasbourgAges 75 years+ - 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 - NCT05068531Recruiting
Detecting early treatment failure in stage IV colon cancer
This study looks for early signs that treatment is not working in people with stage IV colon or rectal cancer that has spread only to the liver. It may help doctors adjust care sooner by using regular blood, stool, and tissue samples around liver procedures.
Montreal, QuebecAges 18 years+ - NCT05072041Recruiting
Degradable chemo bead treatment for liver cancer
This trial studies a new type of “degradable” chemo bead delivered through a catheter to treat hepatocellular carcinoma (HCC). It aims to check safety and whether the treatment works when surgery or transplant is not an option.
Seoul, SeoulAges 19–79 - NCT05072626Recruiting
Special fat formula for babies after biliary atresia surgery
This trial tests whether a special nutritional support formula rich in medium-chain fats can help infants with biliary atresia after the Kasai procedure. It may support feeding and liver recovery during the early months after surgery.
Shanghai, Shanghai MunicipalityAges Up to 3 months - NCT05076175RecruitingPhase 2/Phase 3
Oral ozanimod for children with moderate to severe ulcerative colitis
This trial tests whether an oral medicine called ozanimod can improve ulcerative colitis (UC) in children whose disease is moderate to severe. It’s meant for kids who didn’t fully respond—or couldn’t tolerate—standard UC treatments.
Phoenix, ArizonaAges 2–17 - NCT05075252Recruiting
Testing whether contamination level matters during laparoscopic appendicitis surgery
This study looks at appendicitis patients having laparoscopic surgery and tests whether the amount of contamination found during surgery affects outcomes. It may help surgeons choose the best way to clean the abdomen during the operation.
MilanAges 18–69 - NCT05076760RecruitingPhase 1
Study of a cancer-killing virus with standard treatments
This Phase 1 trial tests MEM-288, an oncolytic (cancer-killing) virus, either alone or combined with standard cancer medicines, in people with advanced solid tumors. It’s designed to see how the treatment works and how safe it is in different cancer types and after specific prior therapies.
Tampa, FloridaAges 18 years+ - NCT05080634Recruiting
Study acid reflux and throat irritation after POEM
This study looks at how often acid reflux (heartburn) and esophagus irritation happen after a procedure called POEM for achalasia, and what factors make it more likely. Your answers and usual tests may help researchers understand who is at higher risk and why.
WarsawAges 18 years+ - NCT05081024Recruiting
Blood test biomarker to help preserve organs in rectal cancer
This study looks at a blood test (ctDNA, a way to detect cancer DNA in the bloodstream) to help doctors choose treatment that may spare organs for people with stage II–III rectal cancer. You may be followed to see how well the blood test can guide treatment decisions.
Portland, OregonAges 18 years+ - NCT05083247RecruitingPhase 2
Pre-surgery chemotherapy plus targeted radiation for borderline pancreatic cancer
This trial studies whether giving chemotherapy before surgery, and possibly adding a focused high-dose radiation treatment, can improve outcomes for people with borderline resectable pancreatic cancer. It aims to shrink or control the cancer and help more patients get to surgery safely.
AntwerpAges 18 years+ - NCT05086614RecruitingPhase 3
Thymosin-alpha 1 after surgery for high-risk colon cancer
This trial looks at whether thymosin-alpha 1, an immune-support treatment, can help prevent colon cancer from coming back after surgery. It targets people with high-risk stage II or III colon cancer who have had the tumor removed.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05086692RecruitingPhase 1/Phase 2
Beta-only IL-2 therapy for advanced solid tumors
This Phase 1/2 study tests a beta-only version of IL-2, an immune-stimulating treatment, to shrink or control advanced or metastatic solid tumors. It’s mainly designed to check safety and to see if it can help patients by improving tumor response.
San Diego, CaliforniaAges 18 years+ - NCT05088798RecruitingPhase 2
PET/MRI scan to help plan surgery for hyperinsulinism
This Phase 2 study uses special PET/MRI imaging to better understand a cause of hyperinsulinemic low blood sugar and guide whether surgery may help. It may help doctors choose the safest plan to reduce severe episodes and protect the brain.
