Recruiting studies7,890 total
- NCT05679583RecruitingPhase 2
Pre-surgery focused radiation for resectable pancreatic cancer

SeoulAges 20 years+ - NCT05679674Recruiting
Radiation plus at-home tumor device for locally advanced pancreatic cancer
This trial tests whether combining targeted radiation with an at-home “tumor treating fields” device can better control locally advanced pancreatic cancer. It may help by attacking cancer cells in more than one way after prior chemotherapy.
Miami, FloridaAges 18 years+ - NCT05680766Recruiting
Exercise training to improve IBS symptoms in inactive people
This trial tests whether a structured exercise program can improve symptoms in people with irritable bowel syndrome (IBS) who currently live a mostly sedentary, inactive lifestyle. It focuses on safety and feasibility (whether the program can be done and what symptom changes may occur).
JetteAges 18–60 - NCT05683730Recruiting
Intermittent calorie restriction for mild to moderate Crohn’s
This trial studies whether planned periods of eating fewer calories can help people with mild to moderate Crohn’s disease. It requires stable Crohn’s treatment and monitoring for weight and health changes during the study.
Vandœuvre-lès-Nancy, CHRU de NancyAges 18–65 - NCT05686226RecruitingPhase 2
Trial tests immune cells targeting HPV-16 cancers
This Phase 2 trial tests an immune-cell treatment (E7 TCR T cells) designed to attack cancers caused by HPV type 16. It may help people whose HPV-16+ cancer has come back or not responded to standard treatment.
Bethesda, MarylandAges 18 years+ - NCT05686499Recruiting
Colonoscopy training for early colorectal cancer detection
This trial supports training for healthcare professionals to improve screening and early diagnosis of colorectal cancer. It may help by building skills in safely performing colonoscopies and spotting cancer earlier.
Ile-Ife, Osun StateAges 18 years+ - NCT05686759RecruitingPhase 3
Tested IV Hepabig in liver-transplant patients with hepatitis B
This Phase 3 study checks whether an undiluted IV infusion of I.V.-Hepabig inj is safe and works to help prevent hepatitis B from coming back after a liver transplant. It is mainly for adults who had a hepatitis B–related liver transplant and already received Hepabig regularly.
Goyang-si, Gyeonggi-doAges 18–64 - NCT05687357RecruitingPhase 2
Tislelizumab plus chemoradiation before surgery for stomach cancer
This Phase 2 trial studies giving tislelizumab (an immune therapy) together with pre-surgery chemoradiation for locally advanced stomach or GEJ (esophagus-stomach junction) adenocarcinoma. It compares this approach to the standard treatment (chemoradiation plus surgery) to see if it improves outcomes.
Wuhan, HubeiAges 18–75 - NCT05687188Recruiting
Study obesity links to pancreatic cancer in specific groups
This study looks at how weight and related body changes may lead to pancreatic tumors, focusing on people who are African American or Non-Hispanic White. It may help researchers better understand why pancreatic cancer risk differs between groups.
Tampa, FloridaAges 18 years+ - NCT05687123RecruitingPhase 1
Adding sunitinib to Lutathera for pancreatic neuroendocrine tumors
This early-phase study tests whether adding sunitinib (a targeted pill) to Lutathera (a radioactive treatment) works better for people with advanced pancreatic neuroendocrine tumors. It also checks safety, since this combination has not been widely studied yet.
Duarte, CaliforniaAges 18 years+ - NCT05687747RecruitingPhase 1
68Ga-FAPI PET/MRI scan for liver cancer diagnosis
This trial studies how well a special imaging test (68Ga-FAPI PET/MRI) can detect and evaluate hepatocellular carcinoma (HCC), a type of liver cancer. It may help doctors confirm diagnosis and plan next steps by seeing how the cancer takes up the tracer.
SingaporeAges 21–99 - NCT05688176Recruiting
Testing blood RNA markers for esophagus cancer and Barrett’s
This study looks for helpful “RNA markers” found in blood to improve diagnosis in people with Barrett’s esophagus or esophageal cancer. It may help doctors spot disease more reliably, but it requires specific health and treatment conditions and a planned biopsy blood sample process.
Ghent, Oost-VlaanderenAges 18 years+ - NCT05689255Recruiting
Study gut bacteria and gut chemistry after gallbladder treatment
This study looks at how your gut bacteria and gut chemical products change after treatment for gallstones. It may help researchers understand what drives symptoms and recovery after surgery and/or endoscopic procedures.
Singapore, SingaporeAges 21–80 - NCT05689645RecruitingPhase 2
Drug trial for liver injury or liver failure
This Phase 2 trial tests an injection medicine (F573) to see if it can improve people with liver injury, drug-related liver damage, or liver failure. You may be screened with blood tests, liver stiffness measurements, and possibly symptom checks.
Beijing, Beijing MunicipalityAges 18–60 - NCT05689775Recruiting
Robot-assisted reconstruction using tummy muscle flap after surgery
This trial studies a specific way to rebuild the pelvic floor (and sometimes the vagina) after major rectal or anal cancer surgery. It uses robotic surgery and a flap taken from your tummy muscle to help close and reconstruct the area.
OsloAges 18 years+ - NCT05690048RecruitingPhase 2
Fecal transplant to help liver cancer respond to standard drugs
This trial studies whether a fecal microbiota transfer (a “gut bacteria transfer” from a donor) can help liver cancer patients overcome resistance to atezolizumab and bevacizumab. It aims to improve how well the standard medicines control the cancer.
Heidelberg, Baden-WurttembergAges 18 years+ - NCT05691348Recruiting
Same-day surgery for uncomplicated acute appendicitis
This trial studies whether removing an uncomplicated appendix in one day (without an overnight hospital stay) is safe and practical. It may help patients recover faster at home, if they meet the trial’s safety requirements.
Nice, Alpes MaritimesAges 15–74 - NCT05691491RecruitingPhase 1/Phase 2
Temozolomide plus M1774 for advanced metastatic cancers
This Phase 1/2 trial tests a combination of temozolomide and M1774 to see how safe it is and whether it can help shrink advanced cancers that have spread. It focuses on certain tumor types and specific biomarker results, and it may be an option if standard treatments have been tried or aren’t possible.
Irvine, CaliforniaAges 18 years+ - NCT05692024RecruitingPhase 1/Phase 2
Coffee and gut bacteria study after colon or rectal cancer
This early-phase study tests whether a coffee-related approach can change gut bacteria and blood “metabolites” after treatment for stage I–III colon or rectal cancer. The goal is to learn if these changes could help improve health after standard cancer treatment.
Boston, MassachusettsAges 18 years+ - NCT05694338Recruiting
Study frailty during major surgery for gut cancer
This trial studies how “frailty” affects people with gastrointestinal (gut) cancer who are about to have major surgery, sometimes after chemotherapy or other treatment beforehand. It may help doctors better prepare and support patients through surgery.
East Corning, New YorkAges 18 years+ - NCT05694559Recruiting
Genetic risk screening and counseling for Black adults
This study connects Black adults to genetic counseling and genetic testing to learn whether they may have an inherited cancer risk. It uses a simple risk screening tool, including visits by phone or video, to guide next steps.
Houston, TexasAges 18 years+ - NCT05694988Recruiting
Filter blood to reduce inflammation in acute pancreatitis
This trial tests whether using blood “filters” plus high-volume fluid filtration can improve outcomes in adults with acute pancreatitis without infection. It aims to remove inflammatory substances from the blood early, while ensuring you’re stable enough for several hours of treatment.
MoscowAges 18–75 - NCT05696002Recruiting
Track outcomes after advanced pelvic cancer surgery
This study follows people who have advanced pelvic cancer surgery that removes more than one pelvic organ. It’s an observational study, meaning it mainly collects data to help improve how future surgeries and care are planned.
GlasgowAges Any age - NCT05696184Recruiting
Studying why reflux reaches the throat and what stops it
This study looks at the “upward reflux” that can irritate the throat and sometimes worsen symptoms like cough or asthma. It aims to understand the mechanisms that prevent or allow throat reflux, which may lead to better ways to manage symptoms.
