Recruiting studies
- NCT05423860Recruiting
HALO prostate study for men with early prostate cancer
This trial studies HALO, a new “human analytics” approach, in men with early-stage prostate cancer. It may help doctors better assess or guide care using MRI and biopsy findings, before or around initial treatment.
Indian Wells, CaliforniaAges 45–90 - NCT05426252RecruitingPhase 1/Phase 2
Lower-toxicity bone marrow conditioning for high-risk thalassemia
This trial tests a modified, lower-toxicity preparation (conditioning) before a bone marrow transplant in children and teens with high-risk thalassemia. It aims to reduce treatment side effects while still allowing transplant success for people who need a donor.
Toronto, OntarioAges 1–18 - NCT05427084RecruitingPhase 2/Phase 3
Canagliflozin to reduce inflammation in heart artery disease
This trial tests canagliflozin to see if it lowers “vascular inflammation” in people with diabetes and stable coronary artery disease. It may help reduce harmful inflammation signals that can raise future heart risk.
Ottawa, OntarioAges 18 years+ - NCT05427370Recruiting
Compare bypass or stent treatment in weak heart patients
This study compares two ways to restore blood flow to the heart—bypass surgery (CABG) or stent procedure (PCI)—in people with a weak pumping heart. It looks at which approach works best when the heart muscle is not pumping well and there are multiple blocked heart arteries.
Los Angeles, CaliforniaAges 18 years+ - NCT05427435Recruiting
Testing alcohol treatment of a heart vein during atrial fibrillation ablation
This study tests whether applying a small amount of alcohol to a specific heart vein (“vein of Marshall”) is safe and feasible during a standard atrial fibrillation (AF) ablation. It may help improve AF treatment, but the goal here is mainly to see if the approach can be done safely in the right patients.
PessacAges 18 years+ - NCT05432518RecruitingEarly Phase 1
Pilot study for surgery and new medicine in recurrent glioblastoma
This early study looks at a treatment plan (including resection/surgery and an added medicine) for glioblastoma that has come back after standard therapy. The goal is to see how well it controls tumor growth and whether it is tolerable.
Calgary, AlbertaAges 18 years+ - NCT05433441Recruiting
Parkinson care team program for people living at home
This study tests whether “Parkinson specialized teams” can improve care for people with Parkinson’s disease who live at home, with help from a main family caregiver. It looks at whether specialized support can be followed over time and whether it helps daily functioning.
BordeauxAges 18 years+ - NCT05436054RecruitingPhase 4
Plenvu vs Picoprep bowel prep for colonoscopy
This study compares two bowel-cleansing products (Plenvu and Picoprep) to see which works better and is easier to tolerate before a colonoscopy. It may help patients by improving the chance of a clear exam and reducing unpleasant side effects.
Aalborg, North JutlandAges 18 years+ - NCT05437198Recruiting
Breath sample study comparing lung bacteria in and out of COPD
This study looks at the germs in exhaled (breathed-out) air to compare people with COPD to people without COPD. It may help researchers better understand lung differences and what could drive COPD.
CréteilAges 18–70 - NCT05437562Recruiting
Trial compares recovery after lower-leg amputation in Veterans
This trial looks at outcomes after a below-knee (lower-leg) amputation in Veterans. It focuses on people who have blood flow likely to heal and who plan to join rehabilitation to walk again with a prosthesis.
Decatur, GeorgiaAges Any age - NCT05437900RecruitingPhase 4
A heart test to guide stent placement using blood-flow measurements
This Phase 4 study tests a way to measure blood flow in heart arteries to help doctors choose the best stent plan. It may help improve safety and effectiveness for people having elective heart stent procedures for stable angina or certain heart attacks.
Aalst, Oost-VlaanderenAges 18–85 - NCT05438121Recruiting
Tests a drug-coated balloon to stabilize clogged heart arteries
This trial studies whether a drug-coated balloon can better treat new, narrowed spots in multiple coronary arteries and “stabilize” the plaque. It may help improve blood flow after a procedure called balloon angioplasty for selected patients.
Ansan-si, Gyeonggi-doAges 18–85 - NCT05439226Recruiting
Diet plan targeting liver fat for type 2 diabetes
This study tests whether a Chinese medical nutrition therapy diet can reduce liver fat and help manage type 2 diabetes in people who also have fatty liver. You may be asked to follow a specific eating plan and keep your diabetes care stable during the study.
Yichang, HubeiAges 18–75 - NCT05439330Recruiting
Dental MRI to help diagnose jaw, gum, and tooth problems
This study tests whether a special dental MRI can give useful pictures to diagnose jaw joint problems, tooth-related tissue changes, and gum/inflammation issues, and to help plan some dental implant treatments. If you need imaging for these reasons, the trial may help doctors choose the best next treatment by using clearer, dedicated scans.
AarhusAges 18 years+ - NCT05443087Recruiting
Checking blood levels of targeted drugs for digestive cancers
This trial monitors how your prescribed targeted cancer medicine moves through your body by doing extra blood tests. The goal is to understand the drug’s levels and dosing in people with advanced digestive cancers, so treatment can be better managed.
AmiensAges 18 years+ - NCT05443516Recruiting
Blood and urine markers in active lupus kidney disease
This study looks at blood and urine markers that may show how active lupus kidney disease is and how it changes over time. It may help doctors better monitor people with active lupus-related kidney inflammation.
BrusselsAges 18–70 - NCT05444452Recruiting
Stent treatment study for blocked heart arteries
This study tests a coronary stent approach for people with significantly blocked heart arteries. It may help by improving blood flow, and it compares treatment in a structured way while monitoring safety and outcomes.
SeoulAges 19 years+ - NCT05450432RecruitingPhase 4
Ketamine maintenance to help prevent suicidal thoughts
This Phase 4 study tests whether ongoing treatment with ketamine or esketamine can reduce suicidal thoughts in people with major depression who are at high risk. Because the study focuses on long-term maintenance, you’d receive treatment over time while being closely monitored for safety and mental health changes.
Boston, MassachusettsAges 18–70 - NCT05452031Recruiting
Sleep program for people with dementia and their caregiver
This study tests a “dyadic” sleep health approach, meaning it works with both you and your caregiver together. It aims to improve sleep when dementia is causing frequent sleep problems, and to see whether a caregiver-involved plan helps both of you.
La Jolla, CaliforniaAges 18 years+ - NCT05453019Recruiting
Cochlear implants and changes in tinnitus symptoms
This study looks at whether a cochlear implant affects tinnitus (ringing in the ears) and related symptoms. It compares people who had tinnitus before surgery with people who did not.
Beijing, FranceAges 16–90 - NCT05453877Recruiting
Brain scan and health data study using a long-term cohort
This study uses existing health records and then collects or uses brain imaging (CT or MRI) along with basic health measurements. It may help researchers learn patterns in brain images that relate to health or disease risk in people from the Kailuan group.
Beijing, Beijing MunicipalityAges 18–90 - NCT05454267Recruiting
Study early blood vessel changes from vaping
This study looks for early signs of blood vessel problems in people who vape and in healthy non-vapers. It may help researchers find ways to detect and prevent vaping-related vascular disease early.

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.
