Recruiting studies
- NCT05723445Recruiting
Low glycemic diet test for diabetes and body changes in CF
This trial studies whether a low glycemic load (a specific way of choosing carbohydrates) improves blood sugar control and body composition in adults with cystic fibrosis–related diabetes. It may help reduce blood sugar problems and support healthier weight and body measurements.
Boston, MassachusettsAges 18–70 - NCT05723653Recruiting
Cell phone social support for people not in HIV care
This study tests a social support intervention delivered through a “support person” (a confidant) to help people stay engaged in HIV care and improve viral suppression. It may help by strengthening support outside of clinic visits and making care easier to follow.
Birmingham, AlabamaAges 18–49 - NCT05724004Recruiting
Alectinib then targeted radiation for ALK-positive lung cancer
This trial tests giving alectinib first, then adding targeted radiation to remaining spots of cancer in people with ALK-rearranged advanced non-small cell lung cancer. It aims to control the cancer after an initial response and help keep disease from progressing.
StockholmAges 20 years+ - NCT05725499Recruiting
Check if skin stimulation lowers blood pressure drops after spinal injury
This study tests a skin “stimulation” treatment to see if it helps stabilize blood pressure in people with spinal cord injury who get low blood pressure when sitting up. If you often have dizziness, faintness, or low readings after changing positions, this trial may help find safer ways to manage it.
West Orange, New JerseyAges 18–75 - NCT05726890Recruiting
Behavior programs to improve infants’ sleep routines
This study tests two behavioral parent-training approaches to help babies with early sleep problems learn to fall asleep and stay asleep with less help. It may help families who want the baby to sleep more independently.
BeershebaAges 9 months–1.5 years - NCT05728229Recruiting
Nutrition program for fatigue after stroke
This study looks at whether a nutrition approach can reduce fatigue in people after a stroke. It will compare the effects of diet-related support during recovery, aiming to help you feel less tired and more active.
Roma, RMAges 55 years+ - NCT05731986Recruiting
Skin nerve stimulation to raise blood pressure after spinal injury
This study tests whether a device that delivers mild electrical stimulation through the skin can improve low blood pressure after an acute spinal cord injury. It may help reduce episodes of dizziness or faint-feeling caused by blood pressure dropping when you sit up.
West Orange, New JerseyAges 18–75 - NCT05733182Recruiting
Lamp color test to prevent nearsightedness in kids
This study tests whether the color of a reading lamp can help reduce how likely children are to become or worsen nearsightedness (myopia). Your child’s eyes may be followed over time to see if the lamp type affects eye measurements.
Hong Kong, KowloonAges 4–18 - NCT05733156Recruiting
Low-dose radiation to trigger whole-body cancer effects
This trial tests whether giving a low dose of radiation to one spot can help shrink cancer in other, untreated areas (the “abscopal effect”) in people with multiple metastases. It may help by boosting the body’s response to stereotactic body radiotherapy (focused high-dose radiation) for tumors outside the brain.
SeoulAges 19 years+ - NCT05736627Recruiting
Compare learning from in-person versus online medical training
This study looks at whether people learn better from in-person training or online training in a medical setting. You may help by taking a course and sharing whether the format affects what you learn.
Frederiksberg, Frederiksberg HospitalAges 18 years+ - NCT05737342Recruiting
Test supplement to lower A1c and steady blood sugar
This trial studies ANKASCIN 568-P products to see if they can lower A1c (a blood sugar average) and help regulate blood glucose. It may help people with early blood sugar problems, but you must avoid diabetes medicines during the study.
TaipeiAges 20 years+ - NCT05737355Recruiting
Test food product for cholesterol balance and lipid levels
This trial tests whether ANKASCIN 568-P products can improve blood cholesterol levels (like LDL and HDL) in people with mild “lipid” (cholesterol/fat) imbalance. It may help by lowering “bad” cholesterol and improving balance, especially if you’re not taking cholesterol-lowering medicine right now.
TaipeiAges 20 years+ - NCT05737732Recruiting
Testing ambient light for multiple myeloma patients
This study looks at whether using a special kind of everyday light (called ambient light) can help people with multiple myeloma as they prepare for their first stem cell transplant. It may be aiming to improve comfort or recovery by affecting sleep and the body’s natural signals from light.
New York, New YorkAges 21 years+ - NCT05744310Recruiting
Long-term ventilation support and quality of life in ALS
This study looks at how long-term breathing support (a ventilation device used over time) affects quality of life for people with ALS and their families. It also asks family members and children about day-to-day well-being during this treatment period.
Bodø, NordlandAges 8 years+ - NCT05744635Recruiting
Study tacrolimus levels after liver transplant
This non-interventional study looks at how tacrolimus blood levels relate to transplant effectiveness and side effects. It uses your existing medical data to understand whether tacrolimus behaves differently from person to person and how that links to safety.
BudapestAges 18 years+ - NCT05744466Recruiting
Compare two psoriasis medicines using real-world patient data
This study looks at how well two common plaque psoriasis medicines—deucravacitinib and apremilast—work in everyday care. It may help researchers understand which option performs better in real patients outside of a traditional drug trial.
Waltham, MassachusettsAges 18 years+ - NCT05745389Recruiting
Alopecia areata registry to track treatment safety and results
This registry collects information from adults with alopecia areata who are starting or taking certain approved medications. It helps researchers understand how well these treatments work and how safe they are in real-world care.
Waltham, MassachusettsAges 18 years+ - NCT05746143RecruitingPhase 4
Zolpidem during recovery after lower-back fusion surgery
This trial studies whether taking zolpidem around the time of recovery from lower-back (lumbar) fusion surgery affects outcomes. It may help doctors understand how sleep medicine can (or can’t) support recovery in certain people.
Los Angeles, CaliforniaAges 18–75 - NCT05748093RecruitingPhase 4
Boost osimertinib levels using cobicistat to improve value
This study tests whether adding cobicistat can increase and stabilize the effect level of osimertinib while keeping treatment cost-effective. You would take osimertinib 80 mg daily, with blood tests to see how your body processes the drug.
Maastricht, LimburgAges 18 years+ - NCT05751811Recruiting
Virtual reality and music to reduce pain during hysteroscopy
This study tests whether virtual reality plus music therapy can help reduce pain during an outpatient hysteroscopy. If you have your procedure at Prince of Wales Hospital, it may be an option to try non-drug comfort methods.
Hong KongAges 18–80 - NCT05753124Recruiting
How weight, diabetes, and bariatric surgery affect pregnancy
This study looks at how weight, blood-sugar problems, and past weight-loss surgery affect pregnancy outcomes. You may be able to help researchers understand what to expect and how to plan care during pregnancy.
LondonAges 18–50 - NCT05753813RecruitingEarly Phase 1
Study lactic acid gel to change vaginal germs
This early study tests whether placing a lactic acid gel inside the vagina can change the vaginal “microbiome,” the mix of germs, to help reduce repeat BV or yeast infections. You may join if you’ve had at least two recent episodes that needed treatment.
Honolulu, HawaiiAges 18–54 - NCT05754073RecruitingPhase 2
Oxytocin to improve bone health in children with autism
This Phase 2 study tests whether oxytocin can help improve bone health in children and teens with autism spectrum disorder. It also checks safety by monitoring symptoms and doing blood tests and imaging.
Boston, MassachusettsAges 6–18 - NCT05755672Recruiting
Study biomarkers during curative-intent treatment for metastatic colon cancer
This study looks at biological markers (substances measured in the body) during treatment for metastatic colorectal cancer. It may help doctors better understand how treatment works, using patients who are treated with a goal of cure.
