Study sedative effects on ongoing brain inflammation after severe COVID
This study looks at whether a specific ICU sedative (dexmedetomidine) affects long-term inflammation in the brain after severe COVID with ARDS and deep sedation. It uses PET and MRI scans and special tracers to understand persistent inflammation and why it may last.
ParisAges 18–74 - NCT05242159Recruiting
COVID-19 antibody study in hospitalized patients
This research study examines a specific type of antibody (anti-annexin A2) that may develop during COVID-19 infection. By studying hospitalized COVID-19 patients, researchers hope to understand whether these antibodies are common and what role they might play in COVID-19 illness.
AmiensAges 18 years+ - NCT05246098Recruiting
Rehabilitation program study for young and adult ICU COVID/respiratory survivors
This study looks at whether a rehabilitation approach improves recovery outcomes for people who survived COVID-19 or a serious breathing infection and needed ICU/PICU care. It may help those still dealing with physical or functional problems after their critical illness.
Calgary, AlbertaAges Any age - 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.
Hong Kong, Hong KongAges 18 years+ - NCT05261139RecruitingPhase 3
Trial for PF-07321332 for children at risk from COVID-19
This trial studies whether PF-07321332 (with ritonavir) helps children under 18 who have COVID-19 at home but are at high risk of severe illness. It looks at whether starting treatment early can reduce progression to worse disease.
Phoenix, ArizonaAges birth–17 years - NCT05268523Recruiting
Online self-management program for long COVID symptoms
This trial tests an online self-management program to help people cope with long COVID symptoms in everyday life. It may help if you’re struggling with ongoing symptoms like mood changes, memory/thinking issues, or physical problems after COVID.
Toronto, OntarioAges 18 years+ - NCT05271669Recruiting
Study of COVID-19 immunity over time
This study looks at how people’s immune protection after COVID-19 may change over time. It aims to better understand immunity, which could help doctors plan future care and prevention.
Hong Kong, HONG KONGAges Any age - NCT05293366Recruiting
Long COVID study testing supportive care for multiple body systems
This study looks at people who have recovered from COVID-19 but still deal with long-term problems. It aims to better understand (and potentially help with) ongoing issues that can affect hormones, metabolism, mood, muscles, the heart, lungs, and skin.
NaplesAges 18 years+ - NCT05308537Recruiting
Mindful compassion program for nurses feeling emotionally exhausted
This study tests whether a mindful compassion training program can reduce psychological distress in nurses who feel emotionally drained. It targets nurses working on COVID-19 hospital units and compares the program to a wait-and-see group.
Verona, ItaliaAges 25–65 - NCT05334615Recruiting
Study of blood clot problems after COVID or flu

Common questions
- Are there clinical trials for covid?
- Yes. Clin2 currently lists 368 recruiting covid studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a covid trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a covid trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
