La Jolla, CaliforniaAges 18–75 - NCT05813964RecruitingPhase 3
Event-driven HIV prevention pill for men who have sex with men
This trial tests a new way to take HIV prevention medicine (PrEP) only around the time you have sex, using a pill called TAF/FTC. It aims to see if this 'on-demand' method is effective, safe, and acceptable, and could offer a more flexible option than taking a pill every day.
ParisAges 18 years+ - NCT04232085RecruitingPhase 2
Stem cell transplant to rebuild immunity in genetic immune disorders
This Phase 2 trial tests a stem cell (bone marrow) transplant approach to restore bone marrow function and immune function in people with certain inherited immune problems. If you have one of these conditions and a suitable donor, the study may offer a path to rebuild blood and immune systems.
Baltimore, MarylandAges 4 months–50 years - NCT05822908RecruitingPhase 1/Phase 2
Study drug VO659 for SCA1, SCA3, and Huntington disease
This early-phase study tests whether VO659 is safe and how the body processes it in people with certain genetic movement disorders (SCA1, SCA3, or Huntington disease). It may help researchers learn the right dose and whether the drug can be given safely.
CopenhagenAges 25–60 - NCT05816382RecruitingPhase 2/Phase 3
Testing TAK-861 for narcolepsy type 1 sleepiness
This Phase 2/3 study tests TAK-861 in people with narcolepsy type 1 (NT1) who already completed an earlier TAK-861 trial. The goal is to see if the medicine remains safe and effective for ongoing central (brain-related) sleepiness problems.
Birmingham, AlabamaAges 16–70 - NCT04874064Recruiting
AI blood tests for triple-negative breast cancer after treatment
This study uses a computer (AI) to read results from blood tests to look for signs of remaining triple-negative breast cancer, before and/or after surgery. It may help doctors better detect residual tumor and guide follow-up care.
London, OntarioAges 18 years+ - 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+ - NCT05824520Recruiting
CT blood-flow test guided treatment versus usual care
This trial compares a treatment plan guided by a special CT scan measurement of blood flow (called CT-derived FFR) versus standard medical therapy. It may help doctors choose the safest, most effective treatment based on how restricted blood flow looks on CT.
Hangzhou, ZhejiangAges 18 years+ - NCT05845489RecruitingPhase 4
Clopidogrel to prevent heart problems from minor artery plaque
This trial tests whether clopidogrel (a blood-thinning medicine) can prevent future heart attacks or strokes in people who have early, “subclinical” plaque in their heart arteries. You may be considered if scans show plaque but not major artery blockage that needs a procedure.
Seoul, OtherAges 40 years+ - NCT05829044Recruiting
How light exposure affects sleep and body clock by sex and age
This study looks at how non-visual light (light that isn’t just for seeing) affects your sleep timing and circadian rhythms, and whether the effects differ by sex and age. It may help researchers design better light-based or sleep-support strategies in the future.
Boston, MassachusettsAges 18–85 - NCT05828823Recruiting
Two-times-a-week dialysis for new patients
This study tests whether starting dialysis at twice a week, instead of the usual three times, is safe and effective for people who still have some kidney function. If the kidneys still make urine and clear waste, being on dialysis less often may maintain that function longer.
Jacksonville, FloridaAges 18 years+ - NCT05838274Recruiting
Study of alcohol effects and brain scans in bipolar disorder
This study gives a controlled amount of alcohol and uses brain MRI scans to understand how alcohol affects people with bipolar disorder. It may help researchers find brain and behavior patterns that explain differences in alcohol responses.
Austin, TexasAges 21–26 - NCT05841784Recruiting
Mindfulness coaching for stress and mood after heart risk
This study tests a structured mindfulness program (MBCT-T) to help people who have elevated stress and/or mild anxiety or depression in the setting of heart disease or heart risk factors. It may help improve emotional well-being and stress levels while you live with these health concerns.
New York, New YorkAges 18 years+ - NCT05842850Recruiting
Study of fatty liver in people born with low birth weight
This trial focuses on people who have fatty liver disease (extra fat in the liver) and were born with low birth weight. It aims to test an approach in this specific group, which may help clarify what helps the liver in higher-risk people.
AarhusAges 35–40 - NCT05826925Recruiting
Care planning for women after pregnancy-related high blood pressure
This study tests ways to improve cardiovascular (heart and blood vessel) care for women after they had high blood pressure during pregnancy. It may help you get better guidance to prevent future heart problems.
Salt Lake City, UtahAges 18 years+ - NCT05816915Recruiting
Lifestyle changes for fatty liver with metabolic health issues
This trial studies whether a lifestyle program can improve fatty liver disease in people who also have metabolic syndrome (a cluster of health problems like high blood sugar and cholesterol). It may help by improving liver health through diet, activity, and other lifestyle changes.
PragueAges 18 years+ - NCT05819008Recruiting
Online brain testing for people with neurological conditions
This trial studies how well a remote, online memory and thinking assessment works for people with neurological disorders or injuries. You may be invited if you can do the computer-based testing and speak Swedish.
UmeåAges 18 years+ - NCT05822388Recruiting
Deep brain stimulation and memory changes in Parkinson’s
This study looks at whether deep brain stimulation (a surgical treatment for Parkinson’s disease) affects thinking and memory over time. It compares Parkinson’s participants to people without Parkinson’s to better understand what changes happen with treatment.
Charleston, South CarolinaAges 18 years+ - NCT05838183Recruiting
Test treatment in people with lung disease and sleep apnea
This trial is studying how a treatment may work for adults who have interstitial lung disease or obstructive sleep apnea. It likely involves sleep testing so the team can measure breathing and sleep patterns.
TianjinAges 18–80 - NCT05822362RecruitingPhase 2
CBD for People with Early Memory Trouble Risk
This Phase 2 study tests whether CBD (a cannabis-derived product) can improve thinking and memory in people who are at risk for Alzheimer’s disease. You would be followed for about 24 weeks with memory/thinking check-ins and require a study partner to help with certain assessments.
Aurora, ColoradoAges 55–85 - NCT05833048Recruiting
Pain-relief nerve block during cardiac surgery
This study tests whether a numbing “nerve block” placed in the rectus sheath area can reduce pain for people having certain heart surgeries with chest tubes. If you qualify, it may help your comfort during recovery, but it also depends on how suitable you are for local anesthesia.
New York, New YorkAges 18–85 - NCT05842915Recruiting
Join a national survey database for musculoskeletal care
This trial builds and studies a national database that collects patient-reported outcomes (answers about symptoms and function) and patient/clinic information for musculoskeletal (muscle and joint) care. It may help improve how these services are delivered by showing what works in real-world primary/community care.
Keele, StaffordshireAges 18 years+ - NCT05841056RecruitingPhase 3

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,546 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.
