Santiago, Santiago MetropolitanAges 18 years+ - NCT05474417Recruiting
Study of how CF carrier status may affect organs

Iowa City, IowaAges 18–100 - NCT05479006Recruiting
tDCS for arm weakness after stroke
This trial tests whether a targeted, noninvasive brain stimulation (tDCS) can improve arm weakness and movement after stroke. It may help people who have significant trouble moving one arm on the side affected by stroke.
Urbana, IllinoisAges 18–90 - NCT05481619RecruitingPhase 4
Vedolizumab study for ulcerative colitis and gut changes
This trial tests whether vedolizumab helps people with moderate-to-severe ulcerative colitis and what changes happen in the gut microbiome (the community of helpful bacteria in your intestines). You may be able to join if you’re an adult with ulcerative colitis who has not used vedolizumab before and haven’t taken certain gut-affecting medicines recently.
Zhengzhou, HangzhouAges 18 years+ - NCT05485675Recruiting
Worksite wellness program to stand and move more
This study tests a workplace program designed to help employees sit less and move more by using stand-and-move practices at work. It may help reduce long periods of sitting, and it also studies how to set the program up successfully at worksites.
Phoenix, ArizonaAges 18 years+ - NCT05498675Recruiting
Sacubitril/valsartan study for high blood pressure by body size
This study tests how sacubitril/valsartan may affect heart function in people with high blood pressure, and whether results differ by body size (BMI). You may benefit by getting closer heart monitoring, though it depends on whether you fit the safety and medical criteria.
Beijing, Beijing MunicipalityAges 18–70 - NCT05499702RecruitingPhase 2
Glucagon test after dieting in type 2 diabetes
This Phase 2 study tests how glucagon affects sugar and fat handling in the liver after a short period of calorie restriction. It may help researchers understand metabolic changes in people with type 2 diabetes and guide future treatments.
Rochester, MinnesotaAges 25–65 - NCT05501262Recruiting
Cryoablation vs steroid injection for Morton’s neuroma pain
This trial compares two ways to treat Morton’s neuroma pain: freezing treatment (cryoablation) versus steroid plus lidocaine injections. It may help people who didn’t improve after trying basic shoe inserts or padding, by seeing which approach works better for symptoms.
Portland, OregonAges 18–105 - NCT05501080Recruiting
Testing a hormone treatment to improve heart changes in PA
This trial tests whether a treatment called SAAE can improve “ventricular remodeling,” meaning changes in the heart muscle, in people with primary aldosteronism (PA). It may help the heart work more efficiently by targeting the cause of high aldosterone levels.
NanchangAges 18–60 - NCT05504928Recruiting
School program to prevent hidden heart valve disease
This study tests whether a prevention program done at a specific school can reduce how common “latent” (hidden) rheumatic heart disease is in children. If you attend the study’s school in Tulsipur, this program may be offered to help protect students’ heart health over time.
Tulsi̇̄purAges 5–16 - NCT05507242RecruitingPhase 2
Drug that blocks TSLP to reduce COPD flare airway inflammation
This Phase 2 trial tests whether blocking TSLP can reduce inflammation in the airways of people with COPD, especially around flare-ups. If you often need prednisone and/or antibiotics for COPD exacerbations, this study may help determine a new treatment approach.
CopenhagenAges 40 years+ - NCT05509387Recruiting
Stronger brain stimulation to improve naming in Alzheimer’s

It may help people who are at higher risk of postoperative confusion by finding the safer anesthesia approach.
SeoulAges 65–100 - NCT05514899RecruitingPhase 2
Cannabidiol and THC study for gut health and brain inflammation in HIV
This Phase 2 study tests whether cannabidiol (CBD) and tetrahydrocannabinol (THC) change the gut microbiome and brain-related inflammation in people with HIV. It may help researchers understand new ways to reduce inflammation, but you would need strict cannabis and CBD/THC avoidance during the study.

- Yes. Clin2 currently lists 6,871 recruiting effectiveness 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 effectiveness 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 effectiveness 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.
