Study genetics in heterotaxy and certain heart defects
This study looks at the genes behind heterotaxy and related congenital (from-birth) heart defects. You may be able to join if you have this condition—or if you are a close family member of someone who does.
Indianapolis, IndianaAges Any age - NCT02848274Recruiting
Looking for factors that predict outcomes in advanced skin lymphoma
This study looks at medical and disease details to find factors that can help predict how advanced mycosis fungoides or Sézary syndrome will behave. Your information may help doctors better estimate prognosis and plan care.
Duarte, CaliforniaAges Any age - NCT02194816Recruiting
Online survey study for people with Parkinson’s or Parkinsonism
This study looks at how changing certain factors over time relates to symptoms in Parkinson’s disease and related conditions. You may help researchers by completing longer online surveys every 6 months for 5 years.
Kenmore, WashingtonAges 19 years+ - NCT02479698RecruitingPhase 2
T Cell treatment for cancers and BK/JC virus illness
This trial studies an infusion of “cytotoxic T lymphocytes” (immune cells) to treat people with certain cancers or illnesses caused by BK and/or JC viruses. It may help your immune system fight the virus and related organ complications when standard treatments have not worked well enough.
Houston, TexasAges Any age - NCT02593565Recruiting
Pregnancy blood-vessel disease registry study
This is a pregnancy registry that collects information from people with certain blood-vessel inflammatory diseases during pregnancy. It helps researchers better understand these conditions in pregnancy and may guide future care.
Tampa, FloridaAges 18–50 - NCT02355457Recruiting
Blood marker study in new heart attack symptoms
This study looks at blood “biomarkers” (signals in blood tests) in people who arrive with symptoms that could be a heart attack. It may help doctors spot and manage acute heart problems sooner and more accurately.
HamburgAges 18 years+ - NCT02762162Recruiting
Registry of heart artery patients’ platelet test results
This registry collects information from people with coronary (heart) artery disease who already had platelet-related blood tests as part of usual care. The goal is to better understand how platelet responses relate to treatment and outcomes, which may help future care.
ParisAges 18 years+ - NCT02781922RecruitingPhase 3
Stem cell infusion for single-ventricle heart failure during surgery
This trial tests whether an infusion of heart stem/progenitor cells can improve outcomes for children with a single working heart chamber (single ventricle) who are scheduled for the next surgical stage (Glenn or Fontan). It may help the heart function after surgery, but participation depends on several heart, lung, brain, and overall health safety criteria.
