Adaptive radiation for advanced throat cancer
This study tests an approach called “adaptive radiotherapy,” where the radiation plan may be adjusted based on how your tumor and anatomy look during treatment. It is for adults with biopsy-proven oropharyngeal (throat) squamous cell carcinoma who are planning curative radiation, with or without chemotherapy.
MelbourneAges 18 years+ - NCT04874012RecruitingPhase 2
Taurine supplement study for blood sugar, fats, and inflammation
This Phase 2 study tests whether taking taurine affects blood sugar control, cholesterol/fats, and inflammation in people with type 2 diabetes. It may help by improving these lab markers, which are linked to long-term health risks.
Porto Alegre, Rio Grande do SulAges 30–80 - NCT04861051RecruitingPhase 1
Study ketamine effects on brain sensations in adults
This Phase 1 study tests how ketamine changes “dissociative” experiences—feelings of being disconnected from thoughts or surroundings—in adults. You may be helping researchers better understand ketamine’s effects, which could guide safer future uses.
Palo Alto, CaliforniaAges 18 years+ - NCT04900597Recruiting
Testing blended tube feeds on kids’ stomach function
This study compares how “blended” tube feeds affect stomach and upper digestive function in children who use a feeding tube. It may help doctors understand whether blended feeds change digestion in ways that matter for comfort and physiology.
Boston, MassachusettsAges 1 year+ - NCT04883515Recruiting
Glutamine drink for insulin resistance and bowel symptoms
This trial studies whether taking an oral glutamine supplement can improve insulin resistance and reduce bowel-related problems in people with obesity and irritable bowel syndrome. It may help your blood sugar regulation and digestive comfort if you meet the criteria.
RouenAges 18–65 - NCT04903223RecruitingPhase 1
Testing how fat in the liver affects statin use in kids
This early study tests whether “liver fat” changes how a statin (rosuvastatin) works in children and teens. It may help doctors choose safer or more effective dosing in kids based on biology and a specific genetics marker.
Kansas City, MissouriAges 8–21 - NCT04916210Recruiting
Study how stroke type affects thinking and recovery
This study looks at what predicts memory and thinking problems after different types of stroke or brain bleeding, and how blood-vessel changes relate to recovery. You may be invited if you recently had a stroke/bleed and can complete a baseline check within 6 weeks.
Phoenix, ArizonaAges 18 years+ - NCT04856410Enrolling by invitation
Spaceflight cognitive testing using MRI brain scans
This study looks at how long-duration space travel affects thinking skills, especially memory and spatial navigation, and what changes happen in the brain. It compares astronauts with healthy volunteer “astronaut surrogates” and uses MRI scans to measure brain function.
Philadelphia, PennsylvaniaAges Any age - NCT04871048Recruiting
tDCS training to reduce cannabis use in people with schizophrenia
