AarhusAges 18–60 - NCT04319627RecruitingPhase 3
Statins to prevent new blood clots after leg clot or lung clot
This trial tests whether taking a statin (rosuvastatin) after a recent leg blood clot (DVT) and/or lung blood clot (PE) can lower the chance of future venous clots. You might benefit if you’re at risk for more clotting and can take the study medication safely.
Calgary, AlbertaAges 18 years+ - NCT04320199Recruiting
Fermented beetle powder for alcohol-related liver problems
This trial tests whether a fermented powder made from a specific beetle can improve or protect the liver after alcohol-related liver injury. It’s looking for people with certain liver blood test levels, and it excludes several conditions and recent herbal or liver-affecting treatments.
Pusan, Ami-dongAges 19 years+ - NCT04325958Recruiting
Test how cannabis affects driving in different age groups
This study looks at how smoked cannabis changes driving performance when compared across two age groups. It may help researchers understand safety risks and differences by age.
Toronto, OntarioAges 19–45 - NCT04328337RecruitingPhase 1/Phase 2
Study tests how rising fatty acids affect brain fuel use
This early-phase study will raise fatty acid levels temporarily and see how the brain uses glucose (sugar) and processes energy. It may help researchers understand how metabolism in the body can change brain function.
Chapel Hill, North CarolinaAges 18–45 - NCT04341155RecruitingPhase 2
Dexamethasone treatment for brain toxoplasmosis in people with HIV
This Phase 2 trial studies whether dexamethasone (a strong anti-inflammatory steroid) helps treat brain toxoplasmosis in adults with HIV. It looks at people who have symptoms and brain scan findings that fit cerebral toxoplasmosis and who have not already taken dexamethasone for more than a few days.
Bandung, West JavaAges 18 years+ - NCT04356287RecruitingPhase 1/Phase 2
Cord cell treatment for severe systemic sclerosis symptoms
This early-phase study tests whether umbilical cord-derived “cord blood–type” cells can reduce or improve severe systemic sclerosis (a type of hardening/scarring disease of connective tissue). It may help people whose current standard treatments haven’t worked or caused side effects.
Montreal, QuebecAges 18 years+ - NCT04354649RecruitingPhase 2
Test triage and treatment for immune-related arthritis from immunotherapy
