This study tests an experimental drug called EDI048 for cryptosporidiosis, a diarrheal disease caused by a parasite. Healthy adults will be deliberately infected with the parasite and then given either EDI048 or a placebo to see if the drug reduces diarrhea severity. The goal is …

This study looks at whether adding echinacea (Immulant®) to standard care can reduce symptoms and parasite levels in children aged 5–12 with weakened immune systems who have cryptosporidiosis, a diarrheal infection. About 60 children will take part. The goal is to see if the supp…

This study is testing a new finger prick device that can detect Toxoplasma infection from a drop of blood. Researchers will compare the device's results to a standard lab test in 210 adults, including pregnant women. The goal is to see if the finger prick test is accurate and eas…

This study looks at how cryptosporidiosis, a diarrheal disease, affects children aged 6 months to 5 years in countries where it is common. Researchers will track how long diarrhea lasts and how dehydrated children become. The goal is to better understand the disease to guide futu…

This study aims to uncover genetic mutations or variations linked to uveitis, an inflammatory eye disease. Researchers will collect blood samples from 1,500 patients with uveitis (including infectious types) and analyze their DNA. The goal is to better understand what causes the …
