Breast cancer radiotherapy side effects study
This study looks at heart and blood-vessel side effects after modern radiation treatment for breast cancer, both soon after and years later. It may help doctors understand who is at risk and how to monitor heart health over time.
ÅlesundAges 30–70 - NCT02553525Enrolling by invitation
Testing different stimulation patterns in Parkinson’s, tremor, and MS
This study tests whether changing the “stimulation pattern” in a deep brain stimulator can improve how well symptoms are controlled. If you are already getting (or replacing) a deep brain stimulator, this may help fine-tune the settings for you.
Gainesville, FloridaAges 21–80 - NCT02564692Enrolling by invitation
APOE gene testing registry to find Alzheimer’s prevention studies
This program enrolls people to get a gene test (APOE) so researchers can match you to Alzheimer’s prevention studies in the future. If you qualify, you do the test but you would not receive your gene test results.
Phoenix, ArizonaAges 50–90 - NCT02203903RecruitingPhase 1
Donor T-cell treatment after transplant for high-risk AML and MDS
This Phase 1 trial studies an advanced form of donated immune cells given after a stem cell transplant to help prevent leukemia coming back. It mainly looks at safety and whether the treatment can work in people with very high-risk AML or MDS who have not relapsed.
Washington D.C., District of ColumbiaAges 6 months–80 years - NCT02414178Enrolling by invitation
Tau PET brain scan for inherited Alzheimer’s disease
This study uses a special brain scan to measure “tau” buildup in people with an inherited form of Alzheimer’s. It may help researchers better understand disease changes and evaluate whether the scan can track them over time.
St Louis, MissouriAges 18 years+ - NCT02290522Recruiting
Personalized cancer treatment study
This trial tests whether tailoring treatment to your tumor's specific genetic makeup can help when standard treatments are no longer working. It may give you access to therapies that are more likely to work for your cancer.
CopenhagenAges 18 years+ - NCT02542683Recruiting
Physical activity program to support children’s brain development
This study looks at whether a structured physical activity program can support thinking and brain development in children around age 2–5. Your child may be eligible if they are having certain surgeries or fit a matched “control” group and do not have specific neurologic or heart-related issues.
