Testing heart artery causes of pain without major blockage
This study looks at people who are being checked for possible heart artery–related chest or similar discomfort, but without major artery blockage (non-obstructive arteries). It aims to help doctors understand what might be causing symptoms and guide safer testing.
Stanford, CaliforniaAges 18 years+ - NCT01055093Recruiting
Study of diabetes complications in adults soon after diagnosis
This study follows adults who have been diagnosed with diabetes recently to better understand diabetes and its complications over time. It also includes a comparison group of people who do not have diabetes to help researchers see what changes are linked to diabetes.
Düsseldorf, North Rhine-WestphaliaAges 18–69 - NCT02049658Recruiting
Using a sniff dog to check for suspected tumors
This trial studies whether a trained sniff dog can help detect or rule out tumors in people with suspicious spots and in healthy people without tumors. It may be useful as a quick screening tool alongside regular medical tests.
Changsha, HunanAges 1 year+ - NCT01890486Recruiting
Collecting information from people having a stem cell transplant
This study aims to collect, store, and share data from patients who are receiving standard intensive treatment and a stem cell transplant from either their own cells or a donor. It may help improve how future patients are treated by building a reliable record of outcomes and care patterns.
Winston-Salem, North CarolinaAges 18–120 - NCT01050504Recruiting
Donate blood and tissue to study recurrent or metastatic cancers
This study collects and studies blood and, when possible, small tissue samples from people with prostate or bladder/urothelial cancer that has come back or spread. The goal is to better understand these cancers and support future research that may lead to better care.
Seattle, WashingtonAges 18 years+ - NCT00029445Recruiting
Blood and Cell Collection Study for HIV Research
This research study collects blood cells from adults with HIV and their family members to understand why some people's immune systems control HIV better than others. Researchers will use your cells to study HIV immunity and develop better treatments.
Bethesda, MarylandAges 18–100 - NCT00254605Recruiting
Retinal photo imaging for inherited eye conditions
This study uses special pictures of the back of your eye (retinal imaging) in people with inherited retinal degeneration. It may help researchers learn how these conditions look and change over time, and it can be a way for you to receive detailed eye imaging.
San Francisco, CaliforniaAges 13 years+ - NCT01311258Recruiting
Tracking leftover cancer cells in AML or high-risk MDS
This study checks for “minimal residual disease,” meaning tiny numbers of leukemia cells that can remain after treatment. Results may help doctors better monitor your response and risk of relapse in AML or high-risk MDS.
Rochester, New YorkAges 18 years+ - NCT01487603Recruiting
Testing a gene test using lung biopsy samples
This study checks whether it’s practical to do gene (DNA) testing on samples taken during EBUS-TBNA, a common breathing-tube biopsy used to stage lung cancer. If it works well, it could make genetic testing faster and easier for people with lung cancer.
Toronto, OntarioAges 18 years+ - NCT01286519Recruiting
Study of how off-label medicines work in young children
This trial measures how medicines behave in the body when they are used in children younger than 8 years for a reason or dose not listed on the official FDA label. It may help doctors choose safer, better doses for children in the future.
Chapel Hill, North CarolinaAges 1 day–8 years - NCT00477100Recruiting
Breast cancer tissue and data registry for research
This trial helps create a research “tissue registry” by collecting breast cancer tissue samples and medical information. It may help doctors better understand inflammatory or invasive breast cancer and improve future studies.
Gilbert, ArizonaAges 18 years+ - NCT00001645Recruiting
