Testing a new drug combo for advanced solid tumors
This trial tests two new drugs, HX009 and IN10018, with or without standard chemotherapy, for people with advanced solid tumors that haven't responded to treatment or have no standard options. It aims to see if this combination can help shrink or control the cancer.

AI tool for grading colitis during colonoscopy
This study uses a special AI system that analyzes images from a colonoscopy to help doctors better understand how active your ulcerative colitis is and predict how it might progress. If you are scheduled for a routine colonoscopy, this AI tool may help your doctor make more precise treatment decisions.
LeuvenAges 18–75 - NCT06709417RecruitingPhase 2
Immunotherapy plus chemo and radiation for advanced esophageal cancer
This trial is testing whether giving a combination of an immunotherapy drug (sintilimab) with chemotherapy, followed by radiation plus more chemotherapy (concurrent chemoradiotherapy), can help people with advanced esophageal cancer that cannot be removed surgically. The goal is to see if this approach shrinks the tumor and improves outcomes.
Shanghai, Shanghai MunicipalityAges 20–75 - NCT06709885RecruitingPhase 2
HDAC inhibitor with chemoimmunotherapy before colon cancer surgery
This trial tests adding an HDAC inhibitor to standard chemotherapy and immunotherapy before surgery for a type of colon cancer called pMMR that has grown into nearby fat or deeper. The goal is to see if this combination can shrink the tumor more effectively and improve outcomes.
Chongqing, Chongqing MunicipalityAges 18 years+ - NCT06710067Recruiting
Urine chemicals for diagnosing disease
This study looks at chemicals in urine to help find new ways to diagnose diseases. You give one urine sample and answer a few questions—no treatment or long-term follow-up needed.
Encinitas, CaliforniaAges 18 years+ - NCT06710665Recruiting
Predicting adjuvant therapy success after esophageal cancer surgery
This trial looks at how well the tumor responded to chemotherapy or radiation before surgery, to see if that can help doctors decide next steps like additional treatment. It may help people with esophageal squamous cell cancer who had the tumor removed completely after initial therapy.
Fuzhou, FujianAges 18 years+ - NCT06711211Recruiting
Digestive cancer registry study
This study collects information from patients with different types of digestive cancers to better understand these diseases and improve future care. It does not test a new treatment, but helps doctors learn more about digestive cancers over time.
Madrid, MadridAges 18 years+ - NCT06712095Recruiting
Video Capsule for Lynch Syndrome Screening
This study tests whether a video capsule (a pill-sized camera you swallow) can help find polyps in people with Lynch syndrome, without needing a colonoscopy. It may be an easier way to screen for colon cancer.
London, (Select)Ages 18 years+ - NCT06712420RecruitingPhase 3
Chemotherapy before surgery for advanced gallbladder cancer
This trial tests whether giving chemotherapy before surgery helps people with locally advanced gallbladder cancer that can still be removed. It may improve outcomes by shrinking the tumor beforehand.
Delhi, National Capital Territory of DelhiAges 18–70 - NCT06713265Recruiting
Parkinson's: freezing while walking and swallowing
This study looks at a possible link between two specific Parkinson's symptoms: freezing while walking and freezing of the throat muscles during swallowing. It aims to understand if people who have one type of freezing are more likely to have the other, which may guide future therapies.
Saint-Sébastien-de-MorsentAges 18 years+ - NCT06713421Recruiting
Pronase to improve stomach cleanliness during endoscopy
This study tests whether a medicine called pronase, taken before an upper endoscopy (a scope test to look at your stomach), helps keep the stomach lining cleaner so the doctor can see better. If you are having a routine upper endoscopy, this might help make the exam more accurate.
ShanghaiAges 18–70 - NCT06713993Recruiting
Esophageal Cancer Study: Using Noninvasive Tests to Guide Care
This study is looking for people newly diagnosed with esophageal cancer or cancer at the stomach-esophagus junction who are planning to have surgery. The goal is to see if certain noninvasive tests (like scans) can help predict how the disease will progress.
BudapestAges 18 years+ - NCT06714357RecruitingPhase 2
Valproic Acid to Boost Anti-EGFR in Colorectal Cancer
This trial tests whether adding valproic acid to standard anti-EGFR plus irinotecan can stop or reverse resistance in metastatic colorectal cancer. It is for patients who previously responded well to an anti-EGFR drug and then progressed.
Caserta, CEAges 18 years+ - NCT06714604RecruitingPhase 3
Comparing standard vs. longer chemo before pancreatic cancer surgery
This trial tests whether taking chemotherapy for a longer period before surgery can help people with borderline or locally advanced pancreatic cancer. It aims to see if a longer treatment course leads to better outcomes.
Gothenburg, VGRAges 18–90 - NCT06714903Recruiting
Gut bacteria and immunotherapy for advanced colon cancer
This study looks at how the bacteria in your gut might affect how well immunotherapy works for advanced colorectal cancer that has spread. It aims to find out if certain gut bacteria can help make treatment more effective.
Changchun, JilinAges 35–75 - NCT06715046Recruiting
Blood DNA test after stem cell transplant
This study checks if looking at DNA in your blood can help doctors see how well your stem cell transplant is working and catch any problems early. It is for people with blood cancers getting a transplant from a donor.
Milan, MilanAges 18 years+ - NCT06715293Recruiting
Wireless sensor capsule for detecting upper GI bleeding
This trial tests a wireless optical sensor capsule that you swallow to find the source of bleeding in your upper stomach or food pipe. It may help doctors diagnose upper gastrointestinal bleeding without a standard endoscopy tube.
Shatin, Hong Kong IslandAges 18 years+ - NCT06715540RecruitingPhase 1
Study of a new drug for healthy male volunteers
This trial tests a new medicine called BCD-261 in healthy men to see if it is safe and how the body processes it. Participants will receive increasing doses and be monitored for about 4 months.
Saint PetersburgAges 18–45 - NCT06715839Recruiting
Digestive cancer imaging study with targeted antibodies
This trial uses a special imaging test (PET scan) to find digestive system cancers. It uses molecules that attach to cancer cells so they light up on the scan, which may help doctors see tumors more clearly.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT06717295Recruiting
Blood test to find cancer early and track treatment
This study uses a blood test that looks at your platelets and immune cells to find common cancers early, and for certain cancers, to monitor how well treatment is working.
