Ankara, AltindağAges 18–65 - NCT07627815RecruitingPhase 2
Safety and Efficacy of PNMR for Long COVID
This study tests whether PNMR (a supplement product) can safely reduce symptoms of long COVID—the lingering fatigue, brain fog, and other problems that some people experience months after COVID infection. You'll take the study product, follow diet and exercise guidelines, and complete questionnaires and a walking test.
Brampton, OntarioAges 19 years+ - NCT07661862Recruiting
Managing heart and lung symptoms after COVID-19
This trial tests a program to help people with ongoing fatigue, shortness of breath, or chest pain after COVID-19. It uses a personalized plan to improve your daily function and heart health.
Hobart, TasmaniaAges 40 years+ - NCT07567274Enrolling by invitationPhase 2
DMSO Therapy for Ringing in Ears After COVID
This trial tests a combination therapy using DMSO (a chemical that penetrates tissues) mixed with several medications to treat persistent ringing in the ears (tinnitus) that developed or worsened after COVID-19 infection or vaccination. If you have bothersome tinnitus linked to long COVID or vaccine injury and haven't responded to previous treatments, this study may help.
Ithaca, New YorkAges 18–70 - NCT07343856Enrolling by invitation
Long COVID diagnostic test study
This study is testing a new, non-invasive way to diagnose Long COVID using a simple bioelectrical assessment. It might help if you've had COVID-19 and have been dealing with ongoing symptoms for 12 weeks or longer.
TashkentAges 18–75 - 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+ - NCT06689345Enrolling by invitation
Brain stimulation study for chronic pain including post-COVID
This study tests if a non-invasive brain stimulation technique can reduce pain in people with chronic pain conditions like fibromyalgia, headaches, or pain that started after COVID-19. It is looking for healthy people and people with ongoing pain to see if the treatment helps.
Sâo Bernardo Do Campo, São PauloAges 18–64 - NCT06560554Enrolling by invitation
Fermented diet for long COVID microbiome health
This study tests whether eating fermented foods (like yogurt, kimchi, or sauerkraut) can improve gut health and ease symptoms in people with long COVID. You'll log your food on your phone and follow a fermented diet for a period of time.
Rochester, MinnesotaAges 18 years+ - NCT06257420Enrolling by invitation
Low-dose rapamycin for ME/CFS and Long-COVID
This trial tests whether a low dose of rapamycin, a drug that may help regulate the immune system, can improve symptoms in people with ME/CFS or Long-COVID.
Palo Alto, CaliforniaAges 18–65 - NCT05831839Enrolling by invitation
Computer training for attention and memory after COVID
This study tests whether computer-based exercises can improve attention and working memory in adults who still have cognitive (thinking) complaints after COVID. It may help if your focus and memory issues have lasted for a while.
Rotterdam, South HollandAges 18 years+ - NCT05369611Enrolling by invitation
Share your COVID-19 experiences in a long-term study
This study asks people already enrolled in the NIEHS SELF cohort to answer a questionnaire about their COVID-19 experiences. Your answers can help researchers understand how COVID-19 affected people in this group.
Bethesda, MarylandAges 23–35 - 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+ - 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+ - NCT07149428Enrolling by invitation
Deep study of smell loss causes using brain scans
This study uses brain imaging and electrical recordings to understand the brain's role in smell loss from any cause—like COVID, sinus problems, or chemotherapy. You may be eligible if you have any degree of smell loss lasting under a year.
Bethesda, MarylandAges 18–99 - NCT07523113Recruiting
Brain Fog Treatment for ME/CFS Using Cognitive Training
This study tests whether a computerized cognitive training program combined with a mild electrical nerve stimulation device (worn on the ear) can help improve thinking and memory problems in people with ME/CFS. The goal is to see if this approach helps with brain fog and daily functioning.
