Study drug for adults with eosinophilic esophagitis (EoE
This Phase 1/2 study tests EP-104GI in adults with eosinophilic esophagitis (EoE), a condition where certain immune cells cause inflammation in the food pipe. It may help improve symptoms and inflammation, and the study also includes a part where people who do well can switch to the active drug.
Sydney, New South WalesAges 18–75 - NCT05610956RecruitingEarly Phase 1
Empagliflozin for mild-to-moderate ulcerative colitis
This early trial studies whether empagliflozin can improve ulcerative colitis symptoms and is safe for people with mild to moderate disease. If it works, it may reduce ongoing colon inflammation and help people feel better.
TantaAges 18–70 - NCT05611034RecruitingPhase 1
Testing a lung treatment for colorectal cancer spread to lungs
This Phase 1 trial tests a targeted treatment delivered to the lungs for colorectal cancer that has spread to the lungs. It aims to see if the approach is safe and can reach lung tumors, especially when there are multiple lung lesions.
Toronto, OntarioAges 18–70 - NCT05613478RecruitingPhase 3
Immunotherapy plus targeted medicine with TACE around liver surgery
This Phase 3 trial tests whether combining camrelizumab and apatinib with TACE before/around liver cancer surgery can improve outcomes for people with certain stages of hepatocellular carcinoma (HCC). It may help by strengthening the immune attack on cancer and by blocking blood supply to tumors.
Nanjing, JiangsuAges 18 years+ - NCT05615779Recruiting
Personalized fiber (B-fructan) diet for inflammatory bowel disease
This trial tests whether a tailored diet high in B-fructans can improve inflammatory bowel disease (ulcerative colitis or IBD-unclassified) in people in mild-to-moderate remission. It may help your gut and reduce bowel inflammation, and it involves colonoscopy and sample collection.
Edmonton, AlbertaAges 6–39 - NCT05615818RecruitingPhase 3
Study of targeted drug choices for advanced bile duct cancers
This Phase 3 trial matches people with advanced bile duct cancer or gallbladder cancer to a specific targeted medicine based on their tumor’s lab results. It aims to improve disease control by using the right drug for the specific changes found in the cancer.
BrusselsAges 18 years+ - NCT05617495Recruiting
Mindfulness training with brain scans for depression
This study tests a mindfulness-based program combined with “brain scan feedback” (fMRI neurofeedback) to see if it can help teenagers and young adults with major depression. It may help by teaching skills and tracking brain activity changes during treatment.
Boston, MassachusettsAges 13–18 - NCT05618145Recruiting
Join a national study database for primary sclerosing cholangitis
This study creates a national database for people diagnosed with primary sclerosing cholangitis (PSC). It may help researchers learn more about the condition by collecting health information from participants.
AnconaAges 17 years+ - NCT05618821RecruitingPhase 2
Indocyanine green dye during stomach surgery for leftover cancer
This Phase 2 study tests whether using a special light-activated dye (indocyanine green) during laparoscopic stomach surgery can improve surgical outcomes for people with remnant (leftover) stomach cancer that has not spread to distant organs. It may help surgeons better find lymph nodes while operating.
Fuzhou, FujianAges 18–75 - NCT05618626Recruiting
Lifestyle program to prevent fatty liver and heart disease
This trial tests whether a structured lifestyle program—focused on healthy living and resistance exercise—can help prevent fatty liver disease and heart-related problems. It may be helpful if you have early or mild fatty liver changes or risk factors, even if you also have gallstones.
Molina, Maule RegionAges 45–60 - NCT05620628RecruitingPhase 2
Test savolitinib plus durvalumab for MET-amplified stomach cancer
This trial studies whether blocking MET (a cancer growth signal) with savolitinib, combined with durvalumab (an immune treatment), can shrink advanced gastric (stomach) cancer that has worsened after chemotherapy. It may help people whose tumors have MET amplification and measurable disease that can be tracked on scans.
SeoulAges 19 years+ - NCT05620771RecruitingPhase 2
Y-90 radioembolization plus treatment for high-risk liver cancer
This Phase 2 trial tests TheraSphere® (a Y-90 radiation treatment delivered to the liver) combined with standard systemic therapy in people with high-risk hepatocellular carcinoma (HCC). It aims to shrink tumors and improve outcomes for people whose liver cancer is at higher risk to worsen.
Chicago, IllinoisAges 18 years+ - NCT05621889RecruitingPhase 1/Phase 2
Virtual speech therapy program for head and neck cancer patients
This trial tests a partner-guided virtual speech therapy program delivered through group sessions and questionnaires for people with head and neck cancer. If you’re starting curative chemo-radiation, the program may help with speech and swallowing-related symptoms during treatment.
Montreal, QuebecAges 18 years+ - NCT05623150Recruiting
Biopsy-based study for alcohol and metabolic liver disease

Genital nerve stimulation to improve bowel control after spinal injury
This trial studies whether stimulating nerves near the genitals (a gentle electrical stimulation approach) can improve bowel function in people with spinal cord injury. It may help bowel control when bowel dysfunction is caused by nerve injury.
Cleveland, OhioAges 18 years+ - NCT05628038RecruitingPhase 2
Radiation plus immunotherapy for recurrent rectal cancer
This Phase 2 trial tests whether giving targeted radiation and an immunotherapy drug together can control locally recurring rectal cancer in the pelvis. It may help shrink tumors and slow disease growth, especially after certain prior treatments.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05628701Recruiting
Testing two UC surgery reconstructions after colectomy
