T cell treatment for stubborn CMV after stem cell transplant
This trial tests a personalized immune cell treatment (CMV-specific T cells) for people whose CMV (a common herpes virus) persists or comes back after a stem cell transplant. It may help your immune system better control CMV when standard antiviral medicines aren’t fully working or can’t be used.
Cleveland, OhioAges 3 months+ - NCT03025074Recruiting
Blood sample bank for liver disease research
This study collects blood samples to build a “biobank” (a stored library of samples) for researchers studying liver diseases like hepatitis, fatty liver disease, and liver cancer. It may help future testing and treatments by allowing scientists to study patterns in people with and without liver conditions.
Buffalo, New YorkAges 7 years+ - NCT03031210RecruitingPhase 2/Phase 3
Twice-daily amoxicillin for mild childhood pneumonia
This trial tests whether twice-daily amoxicillin helps treat non-severe pneumonia in children. It may be a good option if your child has a mild form confirmed by symptoms and a chest X-ray.
Montreal, QuebecAges 3 months–18 years - NCT03044509Recruiting
Testing to diagnose tuberculosis in Swiss children
This trial studies how to diagnose tuberculosis (TB) in children and teens when they are being checked after possible exposure or because TB is suspected. It may help doctors figure out faster and more accurately who has TB infection or disease.
AarauAges Up to 17 years - NCT03059420Recruiting
Genetic study of strabismus and certain birth eye-movement disorders
This study looks for genetic (inherited DNA) causes of strabismus (eyes that don’t line up) and certain birth conditions that affect eye movement and brainstem/cranial nerves. Your participation may help researchers better understand these conditions and guide future testing and care.
Boston, MassachusettsAges 1 day+ - NCT03097952Recruiting
Study of people with long-term hepatitis B in real life
This “real-life” study follows people with chronic hepatitis B to better understand their health over time. It may help researchers learn which factors affect outcomes in everyday care.
Changzhou, JiangsuAges Any age - NCT03120481Recruiting
Check how respiratory health changes in people without lung problems
This trial enrolls adults who recently had a chest X-ray as part of routine health screening and did not show major abnormal findings, and who do not have significant breathing symptoms. It may help researchers understand changes in respiratory health over time and improve how respiratory disease risk is monitored.
Seoul, SeoulAges 19–90 - NCT03132311RecruitingPhase 4
Yellow fever vaccine study for certain people with HIV
This trial checks whether a yellow fever vaccine is safe and works well in adults with HIV who have relatively healthy immune function. It may help doctors understand the best way to protect people with HIV who have never had this vaccine.
Rio de JaneiroAges 18–59 - NCT03136146RecruitingPhase 2
Chemo for return or non-responsive blood cancers
This Phase 2 study tests a combination chemotherapy plan for certain leukemia and lymphoma types that have come back or did not respond. It may help shrink or control disease when standard treatment is no longer working.
Houston, TexasAges 15 years+ - NCT03146676Recruiting
OSU Dermatology Biorepository for donated skin tissue and data
This study collects and stores skin samples and related health information from people seen in OSU Dermatology clinics. It helps researchers better understand skin conditions and may lead to new treatments in the future.
Columbus, OhioAges Any age - NCT03188796RecruitingPhase 3
High-dose vitamin D for ICU patients with low vitamin D
This trial tests whether giving a high dose of vitamin D3 can reduce death within 28 days for critically ill adults in the ICU who have very low vitamin D levels. It may help by correcting vitamin D deficiency, which the study team thinks could affect outcomes in serious illness.
EnzenbachAges 18–100 - NCT03200379Recruiting
Taiwan registry for people treated for hepatitis C
This registry is for people in Taiwan who have received direct-acting antiviral (DAA) treatment for hepatitis C. It collects health information to better understand outcomes and care, and you can join if you agree to participate and sign consent.
