Study of advanced pancreatic cancer using tumor tissue profiles
This study looks at advanced or metastatic pancreatic cancer patients and uses stored tumor tissue to learn what may predict treatment outcomes. You may be able to join if you have had limited prior chemotherapy and can provide an archived tissue sample.
LyonAges 18 years+ - NCT05381038RecruitingPhase 1/Phase 2
Personalized azacitidine combinations for breast or stomach cancer
This Phase 1/2 trial tests different combinations that include azacitidine, chosen based on your tumor’s lab “response markers” and past drug-sensitivity screening. It aims to find safer dosing and see whether these personalized combinations can shrink solid tumors such as breast or stomach cancer.
SingaporeAges 21–99 - NCT05380856Recruiting
Sacral nerve stimulation for bladder, bowel, and sexual symptoms
This trial studies whether sacral neuromodulation (a device that sends mild nerve signals) can improve bladder, bowel, and sexual symptoms caused by nerve problems. It is for people whose current bladder treatments have not worked well enough.
Odense, FynAges 18–80 - NCT05381792Recruiting
Test of gut bacteria changes after colon tumor removal
This study looks at how the gut’s bacteria and bacterial gene signals change after doctors remove certain advanced growths in the colon using endoscopy. If you need an endoscopic procedure for an advanced adenoma or early colon cancer, your stool/bacteria samples may help researchers understand what changes after treatment.
Shatin, New TerritoriesAges 18–90 - NCT05385237Recruiting
4D MRI scan to spot liver scarring
This study tests whether a special MRI scan (called 4D-MRI) can identify liver scarring or damage. It may help doctors measure liver fibrosis and inflammation without relying only on invasive tests.
Liestal, Basel-LandschaftAges 18 years+ - NCT05385549RecruitingPhase 2
5-Year imatinib after GIST surgery for high-risk patients
This study looks at taking imatinib (a targeted anti-cancer pill) for 5 years after your GIST tumor has been fully removed. It is meant to lower the chance that GIST comes back in people considered “high risk.”
Seoul, SeoulAges 20 years+ - NCT05387031Recruiting
Ustekinumab for painful Crohn’s bowel narrowing
This trial tests ustekinumab, a medicine that calms immune inflammation, to see if it can improve symptoms in people with Crohn’s disease that causes bowel narrowing. It may help if your Crohn’s symptoms come from strictures (narrowed areas) seen on scans or endoscopy.
Beijing, Beijing MunicipalityAges 18–65 - NCT05390424Recruiting
Test dried blood spots for hepatitis and HIV
This study checks blood from a simple dried blood spot to screen for hepatitis B, hepatitis C, and HIV. It may help find infections early, which can allow earlier treatment.
AvranchesAges 18 years+ - NCT05391126Recruiting
Genetic test helps choose drug dosing for pancreas or colon cancer
This study tests whether using a genetic test to guide medication doses works better than standard dosing for people with certain pancreas or colon cancers. It may help by tailoring treatment more precisely to your tumor’s genetic features.
Lexington, KentuckyAges 18 years+ - NCT05392413Recruiting
Predicting who benefits from PD-1 antibody for esophageal cancer
This study uses an “immune indicator model” to help predict how well a PD-1 antibody (a cancer-fighting immune drug) works when combined with chemotherapy for stage IV esophageal squamous cell cancer. If you qualify, you receive the treatment and the researchers also look for immune-related signs that may explain who benefits most.
GuangzhouAges 18–75 - NCT05392387Recruiting
Treatment and outcomes study for long-term hepatitis B
This trial looks at people with long-term hepatitis B infection and studies how treatment may affect health over time. It may help you understand whether your care improves outcomes for chronic hepatitis B.
Changsha, HunanAges 18–79 - NCT05393609Recruiting
Quality-of-life study during surgery for diverticular disease
This trial studies how people’s quality of life changes around diverticular disease surgery. It may help doctors understand what to expect and how to better support patients before and after surgery.
Randers, Central JutlandAges 18 years+ - NCT05396456Recruiting
Muscle fragment injections for fecal incontinence symptoms
This trial tests whether injecting your own (autologous) muscle fragments into the anal area can reduce fecal incontinence. It’s for adults with frequent symptoms who have already tried standard medicines and procedures.
Winston-Salem, North CarolinaAges 18 years+ - NCT05396560Recruiting
Stool blood test to decide if follow-up colonoscopy is needed
This trial tests whether a stool blood test can help decide who truly needs a follow-up colonoscopy after prior colon polyps. It may reduce unnecessary colonoscopies while still catching concerning changes early.
Calgary, AlbertaAges 18–74 - NCT05398380Recruiting
Liver transplant for colorectal liver cancer that can’t be removed
This trial studies liver transplantation for certain people with colorectal cancer that has spread only to the liver and cannot be removed with surgery. It aims to improve outcomes for carefully selected patients whose cancer is controlled on chemotherapy and who meet specific safety and scan requirements.
Barcelona, BarcelonaAges 18–70 - NCT05399745Recruiting
Study of biliary atresia in children with heart disease
This trial is studying children who have biliary atresia, a serious liver problem, including some who also have tetralogy of Fallot (a congenital heart condition). It also includes healthy children for comparison, and may help researchers understand the illness and treatments better.
CopenhagenAges birth–18 years - NCT05401318Recruiting
Personalized treatment planning for colorectal cancer surgery
This study focuses on tailoring (customizing) treatment plans for people with colorectal cancer who are scheduled for curative surgery. It may help doctors choose the most appropriate treatment approach after surgery using standard follow-up information.
Lørenskog, AkershusAges 18 years+ - NCT05403177Recruiting
Share your cancer data and samples for Ontario research
This study collects and combines medical records, genetic (genomic) data, and tumor/blood samples from people with cancer. It helps researchers build and improve a large “gold standard” cancer dataset that can support future studies and better understanding of cancer.
Kingston, OntarioAges 18 years+ - NCT05404347Recruiting
Testing treatment response in gallbladder cancer patients
This trial studies how gallbladder cancer responds to treatment. It is for people newly diagnosed who have confirmed cancer in biopsy results.
Varanasi, Uttar PradeshAges 18–99 - NCT05404230Recruiting
Preventing nerve damage from oxaliplatin in the hands and feet
This study looks at ways to prevent numbness or nerve pain in the hands and feet that can happen from oxaliplatin treatment. It includes people with colon or rectal cancer who will be getting standard chemotherapy with capecitabine plus oxaliplatin.
AalborgAges 18 years+ - NCT05406167Recruiting
Tracking quality of life during radiotherapy with a new system
This study collects information about how you feel and how treatment is delivered while you receive radiotherapy using the RefleXion Medical radiotherapy system. It may help doctors improve care and better understand what affects quality of life during treatment.
Duarte, CaliforniaAges Any age - NCT05405673Recruiting
Test stool or tissue genes to find advanced colon growth
This study checks how well a set of bacterial gene markers (a DNA-like test) can help identify advanced “precancer-like” or higher-risk growths in the colon. It may help doctors better target who needs closer follow-up during colonoscopy.
Hong KongAges 18 years+ - NCT05407519RecruitingPhase 2
Tislelizumab and sitravatinib after liver cancer surgery to prevent relapse
This trial studies whether combining two medicines (tislelizumab and sitravatinib) given after curative liver cancer surgery can help prevent the cancer from coming back. It is for people with liver cancer at high risk of recurrence, who have fully recovered from surgery and have no spread beyond the liver.
Hefei, AnhuiAges 18–70 - NCT05408221RecruitingPhase 2/Phase 3
Liver cancer trial testing Rulonilimab plus Lenvatinib
This Phase 2/3 study tests whether combining rulonilimab with lenvatinib can control unresectable advanced liver cancer (HCC) that cannot be removed by surgery or treated locally. You may be considered if you have not had prior whole-body (systemic) cancer treatments and your organs and blood counts are strong enough.
