Hepatoerythropoietic porphyria

This study tests whether a pharmacist-led program can help people reduce their risk of heart disease. Over 1,000 adults with conditions like diabetes, high blood pressure, or obesity are taking part. Pharmacists use a step-by-step guide to assess risk and support lifestyle change…

This study tests whether a stepped alcohol treatment delivered via video or phone calls can help people with advanced liver disease cut back on unhealthy drinking. About 180 participants will be randomly assigned to either the treatment program or usual care. The goal is to see i…

This study compares a new MRI contrast agent, gadopiclenol, to the standard agent, gadoxetate, for imaging liver lesions. Researchers will enroll 23 adults with chronic liver disease or known liver lesions to see if gadopiclenol provides equal or better image quality and lesion v…

This study is testing whether a new blood test score, called GAAD, can detect liver cancer earlier in people with chronic liver disease. The GAAD score combines a person's gender, age, and two blood markers (AFP and PIVKA-II). Researchers will compare the GAAD score to standard u…

This study tests new vitamin and mineral supplements called EasiVits for children aged 1-16 with inborn errors of metabolism (IEM). These supplements have less carbohydrate and no flavor, so they can be used with different diets and kids can add their own taste. The goal is to se…

This study follows up to 500 people with acute or chronic inflammatory disorders, such as infections or immune problems, over time. Researchers will monitor participants with standard tests and may screen them for other studies. The goal is to better understand these conditions a…

This study looks at how lepodisiran enters the blood and leaves the body in people with mild, moderate, or severe liver problems compared to those with healthy livers. About 33 adults will receive a single injection under the skin. The goal is to understand how liver function aff…

This study examines whether the COVID-19 pandemic increased frailty and muscle loss (sarcopenia) in people waiting for a liver transplant. Researchers will compare data from 208 patients assessed before and during the pandemic. The goal is to understand how the pandemic affected …

This study collects blood, urine, and tissue samples from 330 adults with advanced lung or head and neck cancer to improve precision medicine. Researchers will analyze genetic changes in these samples and grow some tumors in mice to compare DNA. The goal is to refine liquid biops…

This study will collect and analyze genetic data from 1000 people with suspected inherited metabolic diseases, including conditions like epilepsy and mitochondrial disorders. Researchers at Karolinska University Hospital aim to improve diagnosis by using advanced genetic testing …

This study was designed to track how COVID-19 infection might worsen the condition of people with inherited metabolic diseases (IMD). Researchers planned to collect information from French patients with IMD who had or had COVID-19 to see how often their metabolic disease got wors…

This study looks at whether an electronic cognitive test called BrainCheck can effectively screen mental function in 100 patients scheduled for liver surgery. Researchers will compare how well patients complete the digital test versus a traditional pen-and-paper assessment. The g…

This study is a registry that will review medical records of 1,000 patients treated for benign or malignant gastrointestinal diseases between 2005 and 2030. Researchers will look at survival, symptoms like heartburn and swallowing trouble, and quality of life. The goal is to lear…

This study planned to test a growth factor medicine (Increlex) in children aged 4-18 with chronic liver disease and short stature. The goal was to see if it could improve growth and quality of life. However, the study was withdrawn before any participants were enrolled, so no res…

This study looks at whether a new ultrasound technique done through the stomach (endoscopic ultrasound elastography) can better predict serious liver problems in people with chronic liver disease. Researchers will measure liver and spleen stiffness in 50 patients and compare resu…

This observational study will follow up to 500,000 adults with chronic liver disease or cirrhosis to understand how the disease progresses and how treatments are used in everyday practice. Researchers will collect data from medical records and patient reports to improve care and …

This study looks at how social factors like income, education, and community support impact recovery in 500 children after liver transplant. Researchers will survey caregivers and interview families to understand barriers to good outcomes. The goal is to find ways to better integ…

This study looks at whether artificial intelligence (AI) can match a dermatologist's diagnosis when a general practitioner sends in photos and questions about a patient's skin condition. Researchers will compare the AI's diagnosis to the dermatologist's for about 1000 adults. The…

This study looks at how a single dose of the experimental drug GZR4 injection behaves in people with mild, moderate, or severe liver impairment compared to those with normal liver function. The goal is to understand the drug's safety and how the body processes it. 36 adults with …

This study planned to test a technique called radiofrequency track cautery during liver, kidney, or spleen biopsies in patients at high risk for bleeding. The idea was to use a small heated probe to seal the biopsy track and reduce bleeding. However, the study was withdrawn befor…

This study watches 200 people with lung, gut, or hormone diseases over time using special brain scans (PET). It aims to see how these diseases change brain activity and whether those changes can predict tumor return, spread, or survival. No new treatment is tested—just observatio…
