Understanding Immunotherapy Response in Liver Cancer
This study collects tumor samples and medical information from patients with liver cancer to understand why some patients respond better to immunotherapy (immune-boosting drugs) than others. The goal is to improve treatment selection and outcomes for future patients.

Study blood, tumor tissue, and preferences to predict stomach cancer response
This study looks at stomach (or stomach–esophagus junction) cancer tissue, treatment details, and patient-reported experiences to better predict how you may respond to standard chemotherapy. It may help personalize future treatment by identifying markers that connect your tumor environment and your expected outcomes.

Single incision gallbladder surgery for acute cholecystitis
This study tests whether removing the gallbladder through a single small cut (single incision laparoscopic cholecystectomy) is safe and effective for people with acute cholecystitis (sudden gallbladder inflammation). It may mean less pain and faster recovery than traditional surgery.

Brief coping exercises for high distress and worry
This study tests brief coping interventions to help people who feel very worried, stuck in negative thoughts, or overly self-critical. You would likely complete short activities using your smartphone and internet while the study checks how your distress changes over time.
New York, New YorkAges 18–65 - NCT06457971Recruiting
Anovo robot for ventral hernia repair
This trial tests a new robotic system called Anovo for repairing ventral hernias. It aims to see if the device is safe and works well for this type of surgery.
BonheidenAges 18 years+ - NCT06698692Recruiting
Preventing low blood counts with trilaciclib after chemoradiation for esophageal cancer
This trial tests an investigational drug called trilaciclib that is given before chemoradiation to help protect your bone marrow and reduce side effects like low blood counts. It is for people with a specific type of esophageal cancer who have finished their main treatment.
Nanjing, JiangsuAges 18 years+ - NCT00590239Recruiting
Study for early changes in Barrett’s esophagus
This study focuses on people with Barrett’s esophagus who are coming in for an endoscopy check or for treatment of early surface changes. The goal is to better understand these early warning areas and how to manage them safely.
Kansas City, MissouriAges 18 years+ - NCT04794582Recruiting
Preventing a belly hernia after first kidney transplant
This trial looks at ways to prevent an incisional hernia (a bulge at the surgical scar) after your first kidney transplant. If you’re getting a first transplant, joining could help test treatments or strategies that lower this post-surgery complication.
MadridAges 18 years+ - NCT05894369Recruiting
Testing how the tumor environment affects pre-op chemo plus immunotherapy
This study looks at people with esophageal squamous cell carcinoma to see how changes in the “tumor neighborhood” may affect how well treatment works before surgery. If you’re eligible, you would receive chemotherapy plus immunotherapy as neoadjuvant (before-surgery) treatment.
Wuhan, HubeiAges 18–80 - NCT06673550Recruiting
Best filling volume for stomach balloon in weight loss
This trial tests how much fluid should be used to fill a stomach balloon to help people with overweight or obesity lose weight. The goal is to find which volume works best and is safest.

Testing a new vagus nerve stimulator for gut and immune health
This study looks at what happens to your immune system and stomach/gut function after getting a vagus nerve stimulator (VNS) for the first time for epilepsy. It may help doctors understand whether the device benefits more than seizures.
Louisville, KentuckyAges birth–60 years - NCT05824975RecruitingPhase 1/Phase 2
Test drug GI-102 alone or with cancer medicines
