HPV cancer trial using immune T cells made for you
This Phase 1/2 trial tests a one-time infusion of special immune T cells made to recognize your HPV16 tumor. It may help your body attack the cancer, while researchers closely monitor safety and early effectiveness.
New Brunswick, New JerseyAges 18 years+ - NCT05639413Recruiting
Study of biology in people with BRAF V600E metastatic colon cancer
This study follows people with BRAF V600E–positive metastatic colorectal (colon) cancer to better understand how the cancer’s biology changes over time. It may help researchers learn which features to watch and how this cancer behaves after initial treatment.
AvignonAges 18 years+ - NCT05640609RecruitingPhase 1/Phase 2
Stomach cancer study using chemo plus immunotherapy plus targeted drug
This Phase 1/2 trial tests a combination treatment for advanced or metastatic stomach and food-pipe (gastroesophageal junction) cancer: a chemotherapy regimen (CapeOX) plus the immunotherapy drug sintilimab and the targeted drug bevacizumab. It aims to see how well this combination controls the cancer and how safely it can be given.
ChengduAges 18–70 - NCT05640947Recruiting
Procedure to reverse bypass using an endoscopic stent
This trial studies a minimally invasive procedure that uses a stent placed through an endoscope to create a new connection in the stomach, with the goal of reversing a Roux-en-y gastric bypass. It may help people whose bypass has led to nutrition problems, severe dumping symptoms, difficult marginal ulcers, or liver scarring that worsens after surgery.
BrugesAges 18 years+ - NCT05641844Recruiting
Minimally invasive treatment for anal fistulas with a seton
This trial tests whether RD2 Ver.02 is safe and works better than a comparison treatment for treating anal fistulas using a less invasive approach. It may help people who have a seton in place and want to avoid major surgery like flap repair or LIFT.
Los Angeles, CaliforniaAges 18 years+ - NCT05642338Recruiting
Testing two sampling methods to monitor Barrett’s esophagus
This study compares two ways of taking tissue samples during endoscopy to check how Barrett’s esophagus is changing. The goal is to improve surveillance, especially for finding early precancer or early cancer changes.
Amsterdam, North HollandAges 18 years+ - NCT05642819Recruiting
MRI before and after surgery for abdominal cancers
This study uses extra detailed MRI scans before and/or around planned abdominal surgery to help researchers understand changes in the body. It includes people having surgery for certain cancers and some people having surgery for non-cancer (benign) conditions.
EdinburghAges 18 years+ - NCT05644717RecruitingPhase 4
Testing erugliflozin for fatty liver and diabetes control
This trial studies whether erugliflozin can reduce liver fat and liver scarring (fibrosis) while also improving blood sugar in people with type 2 diabetes and fatty liver disease (NASH/NAFLD). It’s designed for people who haven’t used certain diabetes medicines like SGLT2 inhibitors or insulin before.
Peshawar, KPKAges 18–65 - NCT05645510Recruiting
Study for people on long-term cancer targeted medicines
This study looks at people who are already taking long-term targeted cancer medicines. It may help researchers understand how these treatments work over time and whether there are ways to improve care.
Edmonton, AlbertaAges 18–90 - NCT05644782Recruiting
