Comparing collagen paste to flap surgery for anal fistula
This trial tests a new collagen paste against standard flap surgery for a type of anal fistula. If you've already had a draining seton placed, you may be able to join this study to see which treatment works better.
Shatin, New TerritoriesAges 18 years+ - NCT06387030Recruiting
EoE biopsy study during endoscopy
This trial looks at taking a small tissue sample during a routine endoscopy to better understand eosinophilic esophagitis (EoE). It may help doctors learn how to diagnose and track EoE more easily.
ParisAges 2–17 - NCT06387342RecruitingPhase 2
Namodenoson for advanced pancreatic cancer
This trial tests an oral drug called Namodenoson for people with advanced pancreatic cancer that has not responded to previous treatments. The goal is to see if the drug can help slow the cancer's growth or improve symptoms.
Petah TikvaAges 18 years+ - NCT06389422RecruitingPhase 2
Radiation plus Keytruda for liver cancer with vein clots
This trial tests a combination of moderate-dose radiation therapy and the immunotherapy drug pembrolizumab (Keytruda) for liver cancer that has spread into the main veins of the liver. It aims to see if this combination can shrink tumors and improve survival.
Beijing, Beijing MunicipalityAges 18–90 - NCT06389448Recruiting
Comparing Two Imaging Methods for Stomach Lesion Diagnosis
This trial compares two special camera methods (pCLE and EB) used during endoscopy to better see and diagnose early stomach changes. It may help doctors decide the best treatment for precancerous spots or very early cancer.
Wuhan, HubeiAges 18–75 - NCT06389760RecruitingPhase 2
Nimotuzumab combo after pancreatic cancer surgery
This trial tests adding nimotuzumab (a targeted therapy) to standard chemotherapy for people whose pancreatic cancer was completely removed with surgery. The goal is to see if this combination helps prevent the cancer from coming back.
Nanjing, JiangsuAges 18 years+ - NCT06389877RecruitingPhase 1/Phase 2
Testing BEAM-302 for alpha-1 antitrypsin deficiency
This trial tests a new treatment called BEAM-302, which aims to correct the genetic defect that causes alpha-1 antitrypsin deficiency. It may help prevent further lung and liver damage in people with the PiZZ mutation.
Birmingham, AlabamaAges 18–70 - NCT06389994Recruiting
String test to monitor esophagus health during allergy treatment
This study tests a new way to check for a condition called eosinophilic esophagitis (EoE) in children getting oral immunotherapy for food allergies. You swallow a small capsule on a string to collect cells from your esophagus—no endoscopy needed.
Philadelphia, PennsylvaniaAges 7–17 - NCT06391892RecruitingPhase 3
Liquid biopsy guided treatment for early pancreatic cancer
This trial uses a liquid biopsy (a simple blood test that looks for cancer DNA) to decide whether you should have chemotherapy before surgery or go straight to surgery. It is for people with pancreatic cancer that has not spread beyond the pancreas.
Linz, Upper AustriaAges 18–99 - NCT06393140Recruiting
Study of how radiation affects the immune system in esophageal cancer
