This Phase 2 study tests the drug Dato-DXd (alone or with other cancer medicines) in people with advanced solid tumors. It looks for tumor shrinkage and how safely the treatment can be given.
Los Angeles, CaliforniaAges 18–130 - NCT05488080Recruiting
Improving emergency care for children with appendicitis or fractures
This project looks at how emergency department care is delivered for children with possible appendicitis or a long bone fracture, with a focus on reducing inequities. You may be eligible if your child comes to the emergency department for symptoms that could fit these conditions, and they are not in the most immediately life-threatening category.
Washington D.C., District of ColumbiaAges birth+ - NCT05488522RecruitingPhase 1
Radiation plus immunotherapy for liver cancer
This early-phase trial tests a treatment plan that combines focused radiation with two medicines—an immunotherapy drug and an anti-angiogenesis drug—to treat hepatocellular carcinoma (liver cancer). It may help shrink tumors or control disease when surgery or ablation can’t be used, and when systemic (whole-body) treatment is needed.
Philadelphia, PennsylvaniaAges 18–99 - NCT05489289RecruitingPhase 3
AK104 to prevent HCC coming back after surgery
This trial tests whether AK104, taken after liver cancer surgery, can lower the chance that the cancer returns. It is for people with high risk of recurrence but no remaining cancer after surgery.
Shanghai, Shanghai MunicipalityAges 18–75 - NCT05490888RecruitingPhase 1
Dose study of PHIN-214 for mild to moderate cirrhosis
This Phase 1 study tests how the medicine PHIN-214 behaves in the body and what dose is tolerable in people with Child-Pugh A or B liver cirrhosis. It may help doctors plan safer dosing for future studies.
Chandler, ArizonaAges 18–75 - NCT05491434Recruiting
Study of muscle loss in colon cancer patients
This trial looks at muscle loss (called sarcopenia) in people with colon cancer to test an intervention that may help strength or recovery. If you’re age 70 or older and meet the cancer and health requirements, you may be able to take part.
L'Hospitalet de Llobregat, BarcelonaAges 70 years+ - NCT05492136Recruiting
Radiofrequency during liver surgery to reduce cancer coming back
This study looks at whether using radiofrequency (a heat-based treatment used during surgery) during liver surgery can lower the chances that cancer returns locally. It includes people with colorectal cancer that has spread to the liver and people with liver cancer (HCC).
BarcelonaAges 18 years+ - NCT05493215RecruitingPhase 2
Imatinib drug-monitoring for GIST with specific gene changes
This Phase 2 trial studies how to adjust and monitor imatinib (a targeted cancer medicine) based on drug levels in the blood. It may help people with GIST that has certain KIT or PDGFRA mutations but not the PDGFRA D842V type.
Lexington, KentuckyAges 18 years+ - NCT05492682RecruitingPhase 1
First-in-human treatment for cancer using a drug injected into tumors
This Phase 1 trial tests PeptiCRAd-1, a treatment injected into a tumor, to see how safe it is and whether it can shrink cancers. It studies people whose cancer has come back or can’t be treated with standard options.
FrankfurtAges 18 years+ - NCT05493605Recruiting
MRI study of heart involvement in Wilson disease
This study looks at whether Wilson disease affects the heart, using MRI scans (and possibly contrast dye). Your results may help doctors better understand cardiac (heart) involvement and how it progresses in Wilson disease.
ParisAges 18 years+ - NCT05494086Recruiting
Laparoscopic stomach surgery for early gastric cancer
This study looks at a surgical technique (“dual-port laparoscopic distal gastrectomy”) for people with stomach adenocarcinoma at an early, specific stage. The goal is to remove the tumor with clean margins (called an “R0” result) and see how this approach works safely.
Guangzhou, GuangdongAges 18–75 - NCT05494060RecruitingPhase 2
Adjuvant chemo plus immunotherapy for ctDNA-positive stomach cancer
This trial tests whether adding an anti-cancer immune treatment and another targeted drug to standard chemotherapy after surgery can lower the chance of cancer coming back. It is for people whose blood test (ctDNA) shows leftover cancer-related DNA after surgery.
Nanjing, JiangsuAges 18–75 - NCT05495152RecruitingPhase 3
Sintilimab after esophageal surgery to help prevent cancer return
This trial looks at adding sintilimab (an immunotherapy) after surgery for certain stages of esophageal squamous cell cancer. The goal is to lower the chance the cancer comes back after standard treatment.
Zhengzhou, HenanAges 18–70 - NCT05495048Recruiting
Transvaginal surgery vs standard laparoscopy for right colon removal
This study compares two surgical approaches for removing the right side of the colon in certain women with colon cancer or a high-risk pre-cancer. It aims to see whether the less invasive transvaginal approach can be done safely and work as well as standard laparoscopic surgery.
ShanghaiAges 18–75 - NCT05495139Recruiting
Gastric bypass stent study for fatty liver disease
This small study tests whether placing a gastric bypass stent can improve nonalcoholic fatty liver disease (fatty liver not caused by heavy alcohol). You may be considered if your liver fat is high on a special MRI scan and you meet several safety and medical history rules.
ShanghaiAges 18–65 - NCT05495776Recruiting
Study checks how often Lynch syndrome happens in colon cancer
This registry study looks at how many people with colon cancer also have Lynch syndrome, an inherited condition that can affect cancer risk. If you enroll, your care team collects basic information from your diagnosis to better estimate how common it is.
MoscowAges 18 years+ - NCT05496998Recruiting
Heart valve replacement using a catheter for leaking mitral valve
This trial studies a catheter-based procedure to replace the mitral valve in people with severe (or specific moderate) mitral valve leakage that causes symptoms. It may help by reducing leaking and related symptoms when standard surgery or less invasive fixes aren’t suitable for you.
AarhusAges 18 years+ - NCT05499702RecruitingPhase 2
Glucagon test after dieting in type 2 diabetes
This Phase 2 study tests how glucagon affects sugar and fat handling in the liver after a short period of calorie restriction. It may help researchers understand metabolic changes in people with type 2 diabetes and guide future treatments.
Rochester, MinnesotaAges 25–65 - NCT05500391RecruitingPhase 2
Testing whether remote nurse monitoring works like in-person checks
This Phase 2 study compares two ways of checking your cancer follow-up: a doctor or nurse visits in person versus remote monitoring by phone and imaging. The goal is to see whether remote monitoring can safely replace or match in-person care for certain low-risk cancers and after surgery.
AmiensAges 18 years+ - NCT05501379Recruiting
Track activity in cancer patients during treatment
This study compares how physical activity answers on a questionnaire match what a motion tracker measures. It may help researchers understand activity levels in people with lymphoma, colorectal, or pancreatic cancer during treatment.
GreifswaldAges 18 years+ - NCT05501587Recruiting
Respiratory Health Registry measuring lung function in different groups
This registry study collects information and measures lung function to better understand respiratory health across people with cystic fibrosis, other lung diseases, and healthy volunteers. Your results may help researchers track lung health and improve future research and care.
Vancouver, British ColumbiaAges birth–99 years - NCT05501353Recruiting
Study tumor biomarkers in recurrent metastatic colon cancer
This study looks for blood/tumor signals (“biomarkers”) that may help predict outcomes in people whose colorectal cancer returns and spreads after surgery. It mainly helps researchers understand who may do better or worse, which can guide future care.
Hangzhou, ZhejiangAges 18–99 - NCT05502133Recruiting
Study genes in families affected by acute intermittent porphyria
This study looks at how genes may affect acute intermittent porphyria (AIP) in families. You may be asked to share health information and provide urine, blood, or saliva samples to help researchers understand what changes genes can make.
New York, New YorkAges 12 years+ - NCT05502198Recruiting
How muscle loss matters in advanced liver disease
This study looks at how loss of muscle strength or mass (sarcopenia) relates to advanced liver disease. It may help doctors understand which patients are at higher risk and could guide future care choices.
