Brain stimulation for mood problems after COVID-19
This study tests if repetitive transcranial magnetic stimulation (rTMS), a non-invasive brain stimulation technique, can help people aged 18 to 65 who have ongoing depression or low mood for more than 12 weeks after a confirmed COVID-19 infection. The treatment uses magnetic pulses to gently stimulate parts of the brain involved in mood regulation.
Zurich, Canton of ZurichAges 18–65 - 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+ - NCT01306084Recruiting
Study of viral infections in healthy and immune-compromised people
This trial studies how viruses affect the body, and how the immune system responds, in both healthy people and people with weakened immunity. It may include people who currently have a suspected or recent viral infection, close contacts, people around the time of a viral vaccine, and healthy adults used for comparison.
Bethesda, MarylandAges 6 months–120 years - NCT04459689Recruiting
COVID-19 study for people with primary immune deficiencies
This study looks at COVID-19 experiences in people who have a primary immune deficiency (a long-term immune problem) and who have had COVID-19. It may help researchers better understand how COVID-19 affects people with these conditions.
ParisAges birth+ - NCT06012552RecruitingPhase 2
Tianeptine for COVID-19 brain fog
This study tests whether the medication tianeptine can improve brain fog and thinking problems that persist after COVID-19. It may help if you are 18 or older, have had COVID-19, and have noticed new memory or concentration issues.
WarsawAges 18 years+ - NCT05131594Enrolling by invitation

Common questions
- Are there clinical trials for covid-19 infection?
- Yes. Clin2 currently lists 195 recruiting covid-19 infection 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-19 infection 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-19 infection 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.
