Recruiting studies
- NCT05476627Recruiting
Study risk factors for kidney disease from metabolic conditions
This study looks at risk factors and body “omics” information (like blood/tissue patterns) to better understand chronic kidney disease caused by metabolic diseases. It may help researchers find better ways to predict or manage kidney problems in people with these conditions.

Gastric bypass stent study for fatty liver disease
This small study tests whether placing a gastric bypass stent can improve nonalcoholic fatty liver disease (fatty liver not caused by heavy alcohol). You may be considered if your liver fat is high on a special MRI scan and you meet several safety and medical history rules.
ShanghaiAges 18–65 - NCT05499091Recruiting
Study rare disease genetics using family and health data
This study tries to find genetic causes for rare diseases that are not yet understood. It uses a national rare-disease data bank and collects consent from patients and sometimes close family members.
AngersAges Any age - 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 - NCT05515367RecruitingPhase 4
Real-world safety study of desidustat for kidney anemia
This study tracks the real-world safety of desidustat in adults with anemia caused by chronic kidney disease (CKD). It’s meant to see whether the medicine is safe when used in everyday care, not just in tightly controlled settings.

Study tracking I2BS in Parkinson’s over time
This study follows people with Parkinson’s to see how “I2BS” changes over time using special brain scans and other tests. It may help researchers better understand Parkinson’s and improve how it’s measured in future trials.
Exeter, DevonAges 25 years+ - NCT05516732Recruiting
Testing serotonin activity in the brain in people with Parkinson’s
This study uses special scans to measure how serotonin is released in parts of the brain involved in movement in Parkinson’s disease. It may help researchers understand disease changes and the role of serotonin systems in movement problems.

Imaging study for inherited Parkinson’s using PET, SPECT, and spinal fluid
This trial tests how well special brain scans (PET/SPECT) and spinal fluid tests can show changes in people with inherited (genetic) Parkinson’s. It may help researchers understand what’s happening in the brain and improve how these conditions are measured.
Exeter, DevonAges 25–80 - NCT05539781Recruiting
Blood flow and brain function monitoring after carotid procedure
This trial studies how blood flow and brain function change after a carotid artery revascularization procedure (opening a narrowed carotid artery). It may help doctors understand what to expect after treatment, especially in people with significant artery narrowing.
Beijing, Beijing MunicipalityAges 18–85 - NCT05550324Recruiting
Pediatric heart disease patient data repository
This trial is a data repository that collects information from children with heart (cardiovascular) conditions and related syndromes. It focuses on organizing cases and comparing groups to help researchers better understand pediatric heart disease.
Columbus, OhioAges Any age - NCT05568498RecruitingPhase 2
Probiotic trial for depression in Parkinson’s disease
This Phase 2 study tests whether taking probiotics can improve depression and mood symptoms in people with Parkinson’s disease. It’s meant for those with mild to moderate depression and stable Parkinson’s and mood treatments.
Vancouver, British ColumbiaAges 40–80 - NCT05597410Recruiting
Study of people at risk for Alzheimer’s in Shanghai
This study follows people who are closely related to someone diagnosed with Alzheimer’s to see who develops memory or brain changes over time. It may help researchers understand risk and early signs, which could guide prevention in families like yours.
Shanghai, Shanghai MunicipalityAges 50 years+ - NCT05610098Recruiting
Study of gene activity in spinal tuberculosis
This trial looks at patterns of gene activity (from blood/tissue samples) in adults with spinal tuberculosis. The goal is to better understand the disease and how to tell different conditions apart, which may help future care.
Cape Town, Western CapeAges 18 years+ - NCT05653440RecruitingPhase 2
Naming therapy training for chronic post-stroke aphasia
This Phase 2 trial studies a speech therapy approach that teaches people with aphasia how to name words, using different learning methods. You may be able to join if your language problem started after a stroke and has lasted more than 6 months.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05653466RecruitingPhase 2
Telehealth therapy schedule for stroke-related aphasia patients
This trial tests an approach that adjusts therapy scheduling for people with long-lasting (over 6 months) language problems after a stroke. It may help some patients by matching the therapy timing to what works best for them.
Pittsburgh, PennsylvaniaAges 18 years+ - NCT05655650Recruiting
Finding blood or brain markers in Alzheimer’s disease
This study looks for “biomarkers,” or measurable signs, that help identify Alzheimer’s disease. It may help doctors diagnose Alzheimer’s more accurately by comparing people with Alzheimer’s to others where the diagnosis is different.
Hong Kong, Hong HongAges 20 years+ - NCT05659901Recruiting
Study tracks symptoms and test results in PLP1-confirmed PMD
This study follows children with Pelizaeus-Merzbacher disease (PMD) who have a specific genetic change (PLP1 duplication). It aims to learn which body measurements (“biomarkers”) and symptoms change over time, to better understand disease progression.
Atlanta, GeorgiaAges 6 months–17 years - NCT05670301Recruiting
Blood test study to profile inflammation biomarkers in diseases
This study measures blood “biomarkers” (signals in blood) to better understand inflammatory diseases, including autoimmune and autoinflammatory conditions. You may be asked to give blood samples now and possibly extra samples if needed for testing.
AntwerpAges Any age - NCT05683093Recruiting
Follow-up study for adults after hypertensive pregnancy
This study follows young adults who previously joined the ALSPAC study to better understand long-term heart and metabolic health after a pregnancy affected by high blood pressure. You may be asked to return for visits and possibly an MRI, and your data may help researchers plan better long-term care.

Study of self-harm in at-risk teens
This study looks at self-harm and thoughts/behaviors related to safety in teenagers who are considered at higher risk. It may help researchers better understand what supports are needed for teens who self-harm without wanting to die.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,813 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.
