Recruiting studies
- NCT05539560Recruiting
Olfactory training for loss of smell after COVID-19
This trial studies whether daily smell training can improve smell loss caused by COVID-19. It may help people regain smell and possibly reduce related symptoms like distorted smells.
CopenhagenAges 18 years+ - NCT05562505Recruiting
Using ECMO to help you breathe, sit up, and come off a ventilator
This trial tests whether a heart-lung machine called venovenous ECMO can help people with severe breathing failure get less sedated, get extubated (have the breathing tube removed), and start moving. It’s for certain adults who are on a ventilator for a short time and have specific oxygenation problems.
Darlinghurst, New South WalesAges 18–65 - NCT05582512Recruiting
Study of long-term effects in children after COVID-19
This study looks at what long-term health effects children may have after getting COVID-19, and how those effects change over time. You may be asked to share health information and possibly complete a scan that can’t be done if certain metal is present.
Taipei, Chung Cheng DistrictAges Up to 18 years - NCT05587894RecruitingPhase 2
Testing optimized COVID antiviral treatment in immunocompromised adults
This study tests the best combination and timing of antiviral medicines for people with COVID-19 who have weakened immune systems. It aims to improve outcomes in people with mild to moderate illness.
Bordeaux, BordeauxAges 16 years+ - NCT05638724Recruiting
Long COVID health registry for people of all ages
This study builds a health registry to learn how long COVID affects children, teens, and adults over time. It may help by improving understanding of symptoms and care, even if it does not test a new drug.
Munich, BavariaAges Any age - NCT05741112Recruiting
Long COVID wearable study to track symptoms and help daily management
This study uses a wearable device to track symptoms and patterns in people with Long COVID, ME/CFS, and/or POTS. The goal is to see how wearable feedback and tracking tools may help you manage your symptoms.
La Jolla, CaliforniaAges 18 years+ - NCT05774093Recruiting
Study how COVID immunity affects reinfection risk
This study looks at how well COVID-19 protection (immune barrier) holds up over time and how likely people are to get reinfected. It may help researchers understand who is more at risk after prior infection and why.
Guangzhou, GuangdongAges Any age - NCT05787379Recruiting
Care program for Veterans with long-lasting COVID symptoms
This trial tests a care approach for Veterans who have long-COVID—aiming to improve symptoms and follow-up care through participating VA clinicians. You may be included if you are a Veteran with long-COVID and can be seen by a participating clinician soon, unless you had severe COVID requiring ICU care.
East Orange, New JerseyAges Any age - NCT05822193Recruiting
Study of long COVID in Brazil
This study looks at how often “post-COVID-19 condition” (long COVID) happens, what factors are linked to it, and how much it affects people’s daily lives. It may help researchers better understand long COVID and who is most impacted.
Cachoeirinha, Rio Grande do SulAges 18 years+ - NCT05851859Recruiting
Breathing training for long COVID symptoms
This study tests whether a structured breathing control technique can improve symptoms of long COVID. It may help by training how you breathe, but you must meet specific health and medication criteria to join.
Saint-DenisAges 18 years+ - NCT05855369RecruitingPhase 2/Phase 3
Smell training plus brain stimulation for long COVID smell loss
This study tests whether a combination of smell training and a type of nerve stimulation can improve persistent smell problems after COVID. It is meant for people who had normal smell before COVID and still struggle with smell changes months later.
Charleston, South CarolinaAges 18–65 - NCT05855330RecruitingPhase 2
Arginine treatment for kids hospitalized with COVID-19
This Phase 2 trial tests whether replacing the body’s arginine (an amino acid) can improve outcomes for children and young adults hospitalized with COVID-19. It may help the immune response, but you must meet several safety criteria to join.
Atlanta, GeorgiaAges 3–21 - NCT05866952Recruiting
Breathing and blood-flow testing in long-COVID symptoms
This trial studies how the lungs’ breathing (airflow) and blood flow may be off in people with long-COVID symptoms like tiredness, shortness of breath, or trouble exercising. It may help researchers understand what’s driving symptoms and what kinds of abnormalities could be targeted.
Boston, MassachusettsAges 18–99 - NCT05880108Recruiting
Behavior program to help COVID recovery in Veterans
This study tests whether a behavioral (lifestyle) program can improve recovery from COVID-19, especially for Veterans with different body weights. It looks at people who either have never had COVID before or had COVID more than 90 days ago.
Baltimore, MarylandAges Up to 80 years - NCT05886816RecruitingPhase 2
Mitoquinone pills to prevent COVID-19 after risky exposure
This trial tests whether an oral medication (mitoquinone/mitoquinol) taken after a high-risk COVID-19 exposure can help prevent you from becoming sick. It is designed for people who currently have no symptoms but had a significant exposure to someone with confirmed COVID-19.
Dallas, TexasAges 18–65 - NCT05890599Recruiting
Yoga or health education for ongoing fatigue after COVID
This trial studies whether a yoga program (compared with health education) can reduce persistent tiredness after COVID-19. It may help if your fatigue has lasted at least 12 weeks and you think it started with COVID.
StuttgartAges 18–65 - NCT05892549Recruiting
Phone-based monitoring to detect worsening COVID-19 early
This study tests whether a phone app that listens to your voice and breathing can spot signs your COVID-19 is getting worse sooner. If you qualify, you’ll use the COVOICE app on your mobile phone for monitoring.
Saint-MandéAges 18 years+ - NCT05894616Recruiting
Home monitoring study for lasting breathing symptoms after COVID
This study looks at people with lingering post-COVID symptoms, especially breathing and lung-related findings, using home monitoring and medical tests. It may help researchers understand what’s driving ongoing symptoms and identify patterns that could guide better care.
Stockholm, SverigeAges 18–50 - NCT05898529Recruiting
Testing COVID status in children having surgery
This study looks at how COVID-19 infection is handled in children (ages 2–17) who are scheduled for surgery. The goal is to compare testing/safety approaches and see how they may protect pediatric surgical patients.
Surrey, British ColumbiaAges 2–17 - NCT05931497Recruiting
Sauna heat treatment for long COVID fatigue
This trial tests whether regular sauna sessions using infrared heat can reduce fatigue from long COVID. You may be eligible if you have ongoing fatigue after a confirmed or strongly suspected COVID infection and can safely spend time lying in a sauna.
Boston, MassachusettsAges 18–65 - NCT06006884Recruiting
Understanding long-term lung effects after COVID-19
