Chicago, IllinoisAges 18 years+ - NCT05193136Recruiting
Testing sleep and exercise effects on strength and thinking in lung disease
This trial studies whether improving sleep habits can help people with lung conditions like COPD or IPF maintain muscle strength and thinking (cognitive function). It may help by addressing sleep quality and related health factors, but eligibility depends on your current diagnoses and treatments.
Jōyō, KyotoAges 20 years+ - NCT05193552RecruitingPhase 4
Spirometry study for people with CVID on IG therapy
This trial looks at how breathing tests (spirometry) can help guide treatment decisions for people with CVID and airway disease who are already on immune globulin (IG) therapy. It may help your care team better monitor lung function using a specific breathing-test pattern.
Birmingham, AlabamaAges 21 years+ - NCT05195450Recruiting
Tenofovir to stop liver disease in mild hepatitis B
This trial tests tenofovir alafenamide (a hepatitis B antiviral medicine) to see if it can prevent liver disease from getting worse in people with chronic hepatitis B who currently have stable (normal) liver blood tests and low virus levels. It may help lower the chance of developing serious liver complications over time.
New Delhi, National Capital Territory of DelhiAges 18–70 - NCT05196698Recruiting
Home high-flow oxygen after COPD hospital flare
This study tests whether using a special oxygen device at home helps prevent another acute COPD flare after you’ve been hospitalized. It’s mainly for people with severe breathing problems who may need oxygen support long-term.
RouenAges 18–85 - NCT05196789Recruiting
Genetic testing to diagnose inherited bone marrow failure
This study looks at patients with suspected inherited (families-linked) bone marrow failure to better understand the cause using genetic testing. It may help confirm a diagnosis and refine how different inherited conditions are classified.
Melbourne, VictoriaAges 3 months+ - NCT05198076Recruiting
TMS follow-up study for balance changes in Parkinson’s
This study looks at how “high-frequency TMS” (a brain stimulation treatment) may change balance in people with Parkinson’s disease over a 6-month follow-up. You may be considered if you have mild to moderate Parkinson’s, have not had TMS before, and are medically stable.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,808 recruiting general population (no specific condition or disease) 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 general population (no specific condition or disease) 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 general population (no specific condition or disease) 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.
