- NCT04363047Enrolling by invitation
Study of immune cells in people linked to COVID-19
This study looks at immune (infection-fighting) cells in people who have previously joined certain healthy volunteer research groups. It may help researchers better understand how the immune system responds to coronavirus infections, including COVID-19.
Manchester, Greater ManchesterAges 18 years+ - NCT04357574Enrolling by invitation
Testing a radiation treatment decision system during COVID-19 changes
This trial looks at whether a computer system can help guide high-intensity radiation treatment decisions when care has been disrupted during COVID-19. It may help improve how treatment is planned and adjusted during times when patients’ situations change.
Durham, North CarolinaAges 18 years+ - NCT04194216Enrolling by invitationPhase 3
Antibiotic prevention during rhinoplasty surgery
This trial studies whether giving antibiotics before and around rhinoplasty (nose reshaping) can lower the risk of infection. If you qualify, you may be randomized to receive antibiotic prevention or another approach to prevention.
Stanford, CaliforniaAges 18 years+ - NCT04190758Enrolling by invitation
Early arthritis study for RA, psoriatic arthritis, and psoriasis
This study looks at people with early arthritis related to rheumatoid arthritis, psoriatic arthritis, or psoriasis. Researchers want to understand how these early conditions behave and may help guide better treatment decisions.
GothenburgAges 18–80 - NCT04178915Enrolling by invitation
Blood marker study to predict severe bacterial lung infection
This study looks at specific immune cells and how fats are transported in the blood to predict which people will have a severe bacterial infection (like pneumonia or sepsis). Your results may help doctors identify higher-risk patients earlier.
MinskAges 18–60 - NCT04129229Enrolling by invitation
Tongue device study for moderate-to-severe sleep apnea and snoring
This trial tests a tongue retractor device to help treat obstructive sleep apnea and reduce snoring in adults. You may be eligible if you have moderate-to-severe sleep apnea and can avoid other common treatments during the study.
Brighton, MassachusettsAges 18 years+ - NCT04016181Enrolling by invitation
Study to categorize lung fibrosis types at a clinic
This study enrolls people who have interstitial lung disease and are seen at the Edinburgh lung fibrosis clinic. It aims to sort different underlying “types” of lung fibrosis so doctors can better understand and potentially guide care.
Ages 18–99 - NCT03856229Enrolling by invitation
Short steroid treatment for lung infection from PCP in HIV
This study tests whether short-term steroid treatment helps adults with a specific lung infection (PCP) that happens with HIV/AIDS. It compares outcomes in people who start steroids soon after admission while also taking standard PCP antibiotics.
México, State of MexicoAges 18–80 - NCT03755245Enrolling by invitation
Imaging study using a tracer to measure inflammation in joints and lungs
This trial tests how a radioactive imaging medicine (a tracer called 68Ga-DOTA-Siglec-9) spreads in the body and how well it shows inflammation. It includes both healthy volunteers and people with active rheumatoid arthritis, vasculitis, or pulmonary sarcoidosis to see if the scan matches disease activity.
TurkuAges 18–70 - NCT03727399Enrolling by invitation
Testing blood for grass or birch allergy antibodies
This study looks at your blood to find allergy-related antibodies if you have pollen allergies to grass or birch. It may help researchers better understand what in the immune system drives allergy symptoms.
Zurich, Canton of ZurichAges 18 years+ - NCT03683186Enrolling by invitationPhase 3
Long-term study of ralinepag for pulmonary hypertension
This study follows people with pulmonary arterial hypertension (PAH) to see how safe and effective ralinepag is over the long term. It may help your care team understand what to expect from continued treatment and monitoring.
Phoenix, ArizonaAges 18 years+ - NCT03589846Enrolling by invitation
Muscle stimulation during a sleep endoscopy test
This trial studies whether muscle stimulation during DISE (a procedure to look at your airway while you’re sedated) can help people with obstructive sleep apnea who can’t tolerate CPAP. Your DISE is part of routine care, and the study adds a muscle stimulation step to see if it changes what’s happening in the throat.
Nashvile, TennesseeAges 18 years+ - NCT03319446Enrolling by invitation
Sharing anonymous samples for a diagnostic test
This trial collects and stores anonymous samples from consenting adults. It helps researchers evaluate or improve diagnostic testing without using your personal identity.
Salt Lake City, UtahAges 18–99 - NCT03295279Enrolling by invitation
Use of chest CT scans from WTC Health Plan participants
This study creates a research archive of chest CT scan images from people enrolled in the World Trade Center (WTC) Health Plan program at Mount Sinai. It may help doctors and researchers better understand and track chest health over time using existing scan images.
New York, New YorkAges 18 years+ - NCT03255408RecruitingPhase 1/Phase 2
Sleep study testing breathing and blood flow in healthy adults
This study looks at how your brain blood flow and breathing change during sleep under normal oxygen and reduced oxygen. It will only include healthy adults so researchers can learn what “intermittent hypoxia” does to the body in people without medical problems.
Calgary, AlbertaAges 18–45 - NCT03149341Enrolling by invitation
MRI and computer-heart simulations for heart disease
This study uses MRI scans and computer simulations to learn more about how the heart and blood flow work in people with certain heart or lung conditions. It may help researchers better understand heart problems and improve future care.
Palo Alto, CaliforniaAges Any age - NCT03062748Enrolling by invitation
Study tests how sleep apnea and inflammation relate to risk
This study looks at people with mild to moderate obstructive sleep apnea (OSA) to understand how inflammation and breathing disruption may affect future heart and metabolism risk. It may help explain why some people develop higher risk even with milder sleep apnea.
Hershey, PennsylvaniaAges 18 years+ - NCT03044847Enrolling by invitation
Long-term study of COPD in adults in China
This study follows people with COPD (chronic lung disease) over many years to better understand the condition. It may help doctors learn what factors predict worsening over time.
Beijing, Beijing MunicipalityAges 40–75 - NCT03010150Recruiting
Blood tests and swallowing exercise check-ins for head and neck cancer
This study looks at whether giving swallowing exercises and checking in with questionnaires can help people with metastatic (spreading to neck lymph nodes) head and neck cancers do the exercises correctly. It also uses blood tests to better understand adherence and progress over time.
Houston, TexasAges 18 years+ - NCT00471978Recruiting
Analyzing DNA from blood and lung tumor tissue
This study looks at DNA from blood samples and lung tumor tissue in people newly diagnosed with primary lung cancer. The goal is to learn more about the cancer’s biology and possibly guide better future care.
