Anti-viral T-cell therapy for stubborn viral infections after transplant
This trial tests a treatment using specially grown T-cells (a type of immune cell) to fight certain viruses that won't go away with standard medicines. It is for people who have had a stem cell or organ transplant, or who have a weak immune system, and who are struggling with adenovirus, CMV, or EBV infections.

Understanding disparities in liver transplant patients
This study looks at differences in health care and outcomes among people waiting for a liver transplant. It aims to understand why some patients face more challenges than others.
Phoenix, ArizonaAges 18–65 - NCT05971433Enrolling by invitation
Studying how body stress signals affect sleep and heart health
This study looks at how “stress signals” in the body after an injury may affect sleep and cardiovascular (heart and blood vessel) health. It may help researchers understand what contributes to recovery and how to improve outcomes for wounded service members.
Bethesda, MarylandAges 18 years+ - NCT05967390Enrolling by invitation
Personalized brain-mapping test using a scalp-to-brain scan
This trial looks at whether a personalized brain “map” using imaging and scalp measurements can be measured and evaluated in people who can safely attend the testing. It may help researchers better understand how brain structure relates to performance, using scan-based measurements and related procedures.
Hong KongAges 60–95 - NCT05956379Enrolling by invitation
Exercise and monitoring study for chronic hepatitis B with fatty liver
This study follows adults with chronic hepatitis B who also have fatty liver and tests an exercise approach to see how it affects liver health. You may be followed over time and helped with an exercise plan if you qualify.
Taipei, Zhongzheng Dist.Ages 18–70 - NCT05932017Enrolling by invitation
Compare two ways to see during gum surgery
This trial compares two tools surgeons use to see during gum (periodontal) surgery: magnifying loupes versus a videoscope. It may help improve how the procedure is done for people with more severe gum disease.
Dallas, TexasAges 18 years+ - NCT05927090Enrolling by invitation
Repair outcomes after acute aortic dissection surgery
This study looks at how patients do after surgery for an urgent (acute) tear of the aorta or related bleeding in the wall of the ascending aorta. It may help doctors better understand what outcomes to expect after early emergency surgery.
Saint-DenisAges 18–90 - NCT05921162Enrolling by invitation
Long-term follow-up after a vision gene eye injection
This study checks how people who previously received a gene therapy eye injection (vMCO-I) are doing over the long term. It may help researchers understand long-lasting effects and safety.
Cuttack, OdishaAges 18 years+ - NCT05919160Enrolling by invitation
New tiny electrode to record brain activity during DBS
This study tests a high-density microelectrode that captures detailed brain recordings while surgeons place a deep brain stimulator for Parkinson’s disease. It may help doctors better locate the exact brain area to target during surgery.
Los Angeles, CaliforniaAges 18 years+ - NCT05859997Enrolling by invitation
CAR-T cell therapy for active autoimmune disease flare-ups
This study tests an immune-cell treatment (CAR-T, called BRL-301) in people with certain autoimmune diseases that are active and hard to control. It may help your immune system calm down if standard treatments have not worked or your disease has returned.
Shanghai, Shanghai MunicipalityAges 18–65 - NCT05826457Enrolling by invitation
Study for early RBD as a possible Parkinson’s risk
This study looks at people with REM sleep behavior disorder (RBD), confirmed by a sleep test, who may be in the early “prodromal” stage before Parkinson’s or related diseases. It also enrolls healthy controls to compare results from brain and body testing to better understand who is at risk.
Los Angeles, CaliforniaAges 18 years+ - NCT05812092Enrolling by invitation
Surgery for one or two levels of neck disc degeneration
This trial studies whether an operation to remove and decompress damaged neck discs (and fuse the area) helps people with painful nerve problems in the neck/arm. It’s meant for cases where non-surgery treatments haven’t worked and imaging shows the problem matches your symptoms.

Study of diabetes prevention participants using brain scans
This study looks at how people who previously took part in a diabetes prevention program are doing over time, including brain health using MRI scans for some participants. It may help researchers understand who is at higher risk for memory and thinking problems and why.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,739 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.
