How Children's Bowel Disease Responds After Switching IBD Medications
This study follows children who had to stop one type of IBD medicine (anti-TNFα) because it caused a skin condition called psoriasis, and were switched to a different medicine called ustekinumab. Researchers want to see how well their bowel disease is controlled with the new treatment.
Nice, FranceAges 6–17 - NCT07530809Recruiting
Time-Restricted Eating for Fatty Liver Disease
This study tests whether eating within a limited time window each day can improve fatty liver disease (a buildup of fat in the liver). If you have moderate-to-advanced fatty liver disease and are overweight, this trial might help you learn if changing when you eat—rather than what you eat—can reduce liver fat and improve your health.
Homburg, SaarlandAges 18–75 - NCT07533864Recruiting
Swallowing Support After Neck Surgery
This trial tests an approach to help patients who develop swallowing difficulties after front-of-neck spine surgery. Researchers will track swallowing problems and test whether a specific care method reduces symptoms.
Hamilton, OntarioAges 18 years+ - NCT07531615Recruiting
Abdominal Pressure Monitoring During Hernia Repair Surgery
This study measures abdominal pressure before, during, and after hernia repair surgery to understand how the body responds to treating hernias. It may help doctors improve surgical techniques and patient recovery.
Nice, Alpes-MaritimesAges 18 years+ - NCT07530445RecruitingPhase 2
Immunotherapy plus chemotherapy for advanced biliary tract cancer
This study tests a combination of two immunotherapy drugs (iparomlimab and tuvonralimab) plus chemotherapy and a targeted drug (lenvatinib) for biliary tract cancer that has spread or cannot be surgically removed. The goal is to slow cancer growth in patients whose cancer has progressed after one prior treatment.
GuangzhouAges 18–70 - NCT07525765Recruiting
AI tool to help decide if you need surgery again after stomach cancer operation
This study uses artificial intelligence to help doctors decide whether patients who bleed after stomach cancer surgery need another operation. Researchers will review medical records and test an AI system to improve decision-making for this serious complication.
Hangzhou, ZhejiangAges 18–90 - NCT07530094RecruitingPhase 2
Radiation and chemotherapy with immunotherapy for advanced esophageal cancer
This trial tests a combination of radiation, chemotherapy (cisplatin and paclitaxel), and an immunotherapy drug called camrelizumab for patients with advanced esophageal squamous cell carcinoma that cannot be surgically removed. The goal is to see if adding immunotherapy improves outcomes compared to standard treatment alone.
Nanjing, JiangsuAges 18–75 - NCT07527026RecruitingPhase 2
Camrelizumab and chemotherapy with radiation for advanced rectal cancer
This trial tests a combination of an immunotherapy drug (camrelizumab) with chemotherapy and radiation to shrink advanced rectal cancer before surgery. The goal is to help more patients have successful surgery with complete tumor removal.
Beijing, Beijing MunicipalityAges 18–75 - NCT07529483RecruitingPhase 2
EUS-Guided Chemoablation for Pancreatic Cysts
This trial tests a new procedure using an ultrasound camera passed through your mouth to inject medicine directly into pancreatic cysts. It may help shrink cysts in people who cannot have surgery.
Columbus, OhioAges 18 years+ - NCT07529626Recruiting
Stress and Pancreatic Cancer Disease Outcomes Study
This research study examines how chronic psychological stress (long-term worry, anxiety, or emotional burden) affects the course of pancreatic cancer and related pancreatic diseases. Understanding this connection may help doctors provide better support and treatment plans for patients.
Changsha, HunanAges 18 years+ - NCT07531342Recruiting
Brain Stimulation and Diet for Severe Crohn's Disease
This study tests whether repetitive transcranial magnetic stimulation (a non-invasive brain treatment) combined with an anti-inflammatory diet can help people with severe, treatment-resistant Crohn's disease feel better. The brain stimulation uses magnetic pulses on the scalp to reduce inflammation and improve symptoms.
Giza, Giza GovernorateAges 40–60 - NCT07533890Recruiting
Probiotics and gut health in children with inflammatory bowel disease
This study tests whether a multi-strain probiotic supplement can change the gut bacteria in children and teens with inflammatory bowel disease (IBD). Researchers will collect stool samples to see if the probiotics help restore healthy gut bacteria and potentially improve symptoms.
BernAges 5–18 - NCT07529301Recruiting
Lung Function Tests Before Surgery to Predict Recovery
This study measures your lung function and physical fitness before surgery to see if these tests can predict how quickly you'll recover. The researchers want to understand which patients might have an easier or harder recovery after their operation.
MalatyaAges 18–80 - NCT06446154RecruitingPhase 2
Fruquintinib after immunotherapy for advanced liver cancer
This trial tests a new drug called fruquintinib for people with advanced liver cancer who have already tried immunotherapy. It may help shrink tumors or slow cancer growth.
Guangzhou, GuangdongAges 18 years+ - NCT06202105Recruiting
Laparoscopic vs open total gastrectomy for advanced stomach cancer
This trial compares two types of surgery for stomach cancer that has grown into deeper layers but has not spread to distant organs. The goal is to see if a keyhole (laparoscopic) approach is as safe and effective as traditional open surgery.
Bien Hoa, Dong NaiAges 18–80 - NCT03941080Recruiting
Study gut bacteria changes in advanced colorectal cancer
This study looks at how gut bacteria (the microbiome) change during treatment for colorectal cancer that has spread or cannot be removed. Researchers hope the findings may help improve understanding of how treatment works and how to tailor care.
AssenAges 18 years+ - NCT05364788Recruiting
Study of tumor tissue in appendiceal cancer after surgery
This study looks at stored tumor samples to better understand appendiceal cancer that has spread to the lining of the abdomen (peritoneal metastases). Your tumor tissue from past procedures may help researchers learn more about the cancer and how it behaves.
ManchesterAges 18 years+ - NCT05344339Recruiting
Compare two stomach reconstruction methods after stomach cancer surgery
This study compares two surgical reconstruction techniques after a distal gastrectomy (removing the lower part of the stomach) for gastric (stomach) cancer. It may help find which method leads to better recovery and outcomes after surgery.
