BrestAges 10 months–11 months - NCT03101722Enrolling by invitation
Huperzine A for hearing loss, tinnitus, and mild memory issues
This trial tests whether huperzine A can improve hearing-related symptoms along with tinnitus (ringing) and mild cognitive (memory/thinking) problems. If you have mild-to-moderate hearing loss plus bothersome constant tinnitus and some cognitive decline, this study may help researchers see if the treatment makes a difference.
Shanghai, Shanghai MunicipalityAges 60 years+ - NCT02784210RecruitingPhase 2
Steroid treatment to reduce inflammation in active MS lesions
This Phase 2 study tests whether corticosteroid medicine can reduce inflammation at the edge of active multiple sclerosis (MS) plaques seen on MRI. It may help calm “hot” areas in the brain where MS activity is happening.
Bethesda, MarylandAges 18–120 - NCT02890485Recruiting
Dry needling for knee pain with stair or squat pain
This study tests whether dry needling can reduce ongoing knee pain in people who feel pain around the kneecap when going up or down stairs, squatting, or running. You may be able to join if your knee pain has lasted at least 3 months and you’re referred to physical therapy.
Columbus, OhioAges 18–40 - NCT02960737Recruiting
Training for swallowing problems after stroke
This trial studies whether a specific oral training program can improve swallowing after a stroke. It’s mainly for people whose swallowing trouble has lasted for several weeks after their stroke.
UmeåAges 18 years+ - NCT02392442Enrolling by invitationPhase 2
Study drug-free lung irritation using endotoxin in healthy adults
This trial tests how putting a small amount of endotoxin into a specific part of the lung affects the body. It’s designed for healthy, nonsmoking adults, and may help researchers understand lung and immune responses.
Bethesda, MarylandAges 18–45 - NCT02216500Recruiting
Study ketogenic diet effects in people with epilepsy
This study looks at how a high-fat, low-carbohydrate ketogenic diet may change electrical activity in the brain and related body measurements in people with epilepsy. You may be asked to follow the diet and keep records so the researchers can compare changes over time.
Gainesville, FloridaAges Up to 50 years - NCT02666625Recruiting
Research biobank for adults treated for childhood cancer
This study collects blood samples from adults who had cancer as children. The samples will be stored in a biobank for future research on the long-term effects of childhood cancer treatment.
