Recruiting studies
- NCT07074158Enrolling by invitation
Looking for long COVID clues in blood
This study compares the blood of people with ongoing long COVID symptoms to healthy people, to look for differences in immune signals and gut bacteria. It could help find better ways to diagnose or treat long COVID.
Palo Alto, CaliforniaAges 18 years+ - NCT05228691Recruiting
Study Long COVID symptoms in the Canary Islands
This study looks at how common long-term COVID symptoms are in people across the Canary Islands. It may help researchers better understand who is affected and what symptoms last, which can support future care.
Las Palmas de Gran Canaria, Las PalmasAges 18 years+ - NCT05131594Enrolling by invitation
Study immune response in Long COVID patients
This trial studies how your immune system responds in people with Long COVID after a past COVID-19 infection. It may help researchers understand why symptoms linger and how the body’s response could be targeted.
Pasadena, CaliforniaAges 18 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 - NCT04444128Recruiting
Testing heart risk assessment using MRI T1 mapping
This study checks whether an MRI heart scan measure called “T1 mapping” can improve how doctors estimate heart disease risk in everyday people. You may join if you’re an adult and can have a contrast-enhanced heart MRI safely.
Frankfurt am Main, HesseAges 18 years+ - NCT04806620Recruiting
Online app study for brain inflammation lifestyle data
This study uses a digital platform (app/website) to collect lifestyle and symptom information to better understand brain inflammation. You may qualify if you have certain conditions like Long COVID, migraines, autoimmune disease, inflammatory gut issues, mood disorders, or if you are a healthy comparison person.
Delafield, WisconsinAges 2 years+ - NCT07224490RecruitingPhase 1
Kisspeptin test for brain function after COVID-19
This study tests how the brain's reproductive hormone system works after a COVID-19 infection using a substance called kisspeptin. It may help explain symptoms like changes in periods or hormone levels in people with long COVID.
Boston, MassachusettsAges 18–60 - NCT05190718Recruiting
Pharyngeal electrical stimulation for swallowing trouble after brain injury
This trial tests a non-drug therapy that uses gentle electrical stimulation to help people swallow safely when swallowing is affected by certain brain or nerve conditions. If you qualify, you may receive this approach to improve swallowing and reduce choking risk.
Tulln, Low AustriaAges 18 years+ - NCT05566483Recruiting
Study long COVID physiology and cardiopulmonary rehab effects
This study looks at how long COVID affects the body and whether cardiopulmonary rehabilitation improves quality of life and physical function. It may help participants better understand their symptoms and see if a structured rehab program improves daily abilities.
Aurora, ColoradoAges 18 years+ - NCT05764538RecruitingPhase 2
Drug trial for brain fog after COVID-19
This Phase 2 trial tests DAOIB to improve “brain fog” and thinking problems that happen after COVID-19. You may be screened if your symptoms started after a COVID infection and have lasted for months, and if your health tests are normal.
Kaohsiung CityAges 18–100 - NCT05833217Recruiting
Study for persistent COVID symptoms with insulin resistance
This trial studies people who have ongoing effects after COVID (often called PASC) and may be related to weight and insulin resistance. It may help researchers find better ways to understand the condition and improve treatment.
Palo Alto, CaliforniaAges 18–80 - NCT06366724RecruitingPhase 2
Life Improvement Trial for ME/CFS
This trial tests a new treatment for ME/CFS (chronic fatigue syndrome) that includes symptoms like dizziness when standing. It uses a smartphone app to track your progress and aims to see if the treatment can improve your daily life.
Boston, MassachusettsAges 18–70 - NCT06850350Recruiting
Long COVID and Thinking & Walking
This study looks at how Long COVID affects thinking and movement skills. If you had COVID-19 more than 3 months ago and could walk before you got sick, you may be able to help researchers understand these lasting symptoms.
Chicago, IllinoisAges 18 years+ - NCT06932237Recruiting
Immune causes of long COVID brain symptoms in veterans
This study is for veterans who have long COVID with brain or nerve symptoms. It looks at how the immune system may be causing these ongoing symptoms.
Portland, OregonAges 18–80 - NCT06933173Recruiting
Mind-body therapy for Long COVID and ME/CFS
This trial tests whether a specific mind-body program can help people with Long COVID or ME/CFS feel better. It compares the program to standard care to see if it improves symptoms like fatigue and brain fog.
Calgary, AlbertaAges 18 years+ - NCT04362150Recruiting
Study of long-term effects after COVID-19 infection
This study follows adults who had COVID-19 to learn how the illness can affect health over the long term. It may help researchers understand lasting symptoms and who is at higher risk, which could improve future care.
San Francisco, CaliforniaAges 18–100 - NCT05248412Recruiting
Study how COVID-19 long-term effects impact chronic diseases
This research looks at how the COVID-19 pandemic has affected the health and healthcare of adults with long-term conditions like diabetes, high blood pressure, heart disease, cancer, kidney disease, or chronic lung disease. It compares people who may have been affected by the pandemic and looks at their health and access to care over time.
