Recruiting studies
- NCT06098612RecruitingEarly Phase 1
PET imaging study for Parkinson's and related disorders

Charlestown, MassachusettsAges 50–80 - NCT05336695RecruitingPhase 1/Phase 2
Brain scan study to measure fibrin in Alzheimer’s
This early study (Phase 1/2) uses brain imaging to look for “fibrin” (a blood-clot–related protein) in people with Alzheimer’s disease and related conditions. The goal is to understand whether fibrin changes can be seen on scans and what it might mean for Alzheimer’s.
Boston, MassachusettsAges 55–90 - NCT06072911Recruiting
Men's health after prostate cancer surgery study
This study looks at how men recover control of urine and sexual function after prostate removal surgery. It also tests if a 12-week exercise program can help improve these functions.
Edmonton, AlbertaAges 18 years+ - NCT06055452RecruitingPhase 4
SGLT2 Inhibitors for Pre-Heart Failure with Hypertension
This trial tests if a medicine (SGLT2 inhibitor) given to people with high blood pressure and early signs of heart stress can help prevent heart failure. You may join if your blood pressure is controlled but tests show your heart is beginning to struggle.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06051058Recruiting
App for managing health after hospital discharge
This study tests a smartphone app designed to help people with multiple health conditions manage their care after leaving the hospital. It may help you feel more supported and avoid confusion during the transition from hospital to home.
Boston, MassachusettsAges 55 years+ - NCT06016257Recruiting
Virtual home exercise program for shoulder rehab
This study tests a virtual home exercise program (VirtuaCare) for people with shoulder problems who need physical therapy. It aims to see if doing exercises at home with virtual guidance works as well as standard care.
Los Angeles, CaliforniaAges 18 years+ - NCT06003153RecruitingPhase 4
Gene and sugar response study with oral semaglutide
This study looks at how your genes affect your body's response to a diabetes medication called semaglutide. It may help people with slightly high blood sugar (pre-diabetes) understand why some respond better than others.
Boston, MassachusettsAges 18–65 - NCT05990179Recruiting
Screening newborns for rare diseases using genetics
This trial offers free genetic screening for rare diseases in newborns. It aims to find health conditions early so babies can get the right care sooner.
New York, New YorkAges 1 day–1 month - NCT05981183Recruiting
Vagus nerve stimulation for chronic kidney disease
This study tests a device that gently stimulates a nerve in your ear to see if it can help people with chronic kidney disease (CKD). The device is non-invasive and may improve how your body handles kidney-related issues.
New York, New YorkAges 18–80 - NCT02998411Recruiting
Blood sample study of antibiotics in hospitalized patients
This study looks at how antibiotics move through the body in adults who are hospitalized. By measuring antibiotic levels in blood (or other body samples), the team may better understand dosing for safer, more effective treatment.
Paris, ParisAges 18 years+ - NCT05952999Enrolling by invitation
Studying Hospital-At-Home care done from home
This trial looks at how well a “Hospital at Home” program works when people start from the emergency department or are already in the hospital and can be cared for at home. It may help teams improve care at home for certain medical conditions and situations.
Peoria, IllinoisAges 18 years+ - NCT04542720Recruiting
Nerve-Pressure Surgery Alone or With Spine Fusion
This trial compares two surgical options for the level just above a prior lumbar fusion: removing pressure on the nerve versus removing pressure plus adding a fusion. It may help determine which approach better treats ongoing nerve-related symptoms when other non-surgical treatments have not worked.
Boston, MassachusettsAges 18 years+ - NCT05875870Recruiting
Bright light and exercise program for lung or esophageal cancer
This trial tests whether a structured bright-light exposure routine combined with a specific exercise program can help people with newly diagnosed lung or esophageal cancer. You may be eligible if you’re in early-to-middle cancer stages and able to safely participate in walking-based activities.
Taipei City, TaipeiAges 20 years+ - NCT05799222Recruiting
Nutrition program for obesity and diabetes risk
This trial tests a medically guided nutrition program to help improve weight and blood sugar in adults with obesity or early diabetes risk. It specifically targets people who meet income guidelines and don’t already use most diabetes or anti-obesity medicines.
Boston, MassachusettsAges 18–65 - NCT05787574RecruitingPhase 2
Reducing inflammation before stem cell transplant in immune disorders
This Phase 2 study tests medicines that calm inflammation before the first stem cell transplant. It aims to make transplant safer and more effective for people with certain inherited immune regulation or inflammatory conditions.
San Francisco, CaliforniaAges Any age - NCT05786417RecruitingPhase 4
Medication comparison for older adults with stable heart pain
This trial tests which heart medications work best for older adults who have stable angina (predictable chest pain) and multiple other long-term health problems. You may be asked to start or adjust medications and attend regular follow-up visits to see which approach controls symptoms and outcomes.
New Haven, ConnecticutAges 65 years+ - NCT05719441RecruitingPhase 2
Testing HIV antibodies plus early HIV treatment for possible remission
This trial tests whether giving two powerful HIV-fighting antibodies (called broadly neutralizing monoclonal antibodies) along with starting standard HIV medications soon after infection can help control the virus without needing daily pills. If successful, it might allow people to take a 'treatment pause' while keeping their immune system healthy.
Birmingham, AlabamaAges 18–70 - NCT05645003Recruiting
Brain stimulation therapy for nerve pain after spinal cord injury
This trial tests whether painless magnetic stimulation of the brain (non-surgical) can reduce long-lasting nerve pain after spinal cord injury. It may help people whose spinal cord injury-related pain has been present for at least six months.
AfyonkarahisarAges 20–70 - NCT05580458RecruitingPhase 1/Phase 2
Shingles vaccine study for adults with well-controlled HIV
This Phase 1/2 study tests how safe and how well a shingles (varicella zoster) vaccine works in adults living with HIV whose immune status is measured by CD4 count, plus a healthy comparison group. It may help researchers understand whether the vaccine can safely boost protection in people with HIV.
Bethesda, MarylandAges 18 years+ - NCT05519475RecruitingPhase 2
Gene-silencing medicine trial for adults with MASH and liver scarring
This Phase 2 study tests a gene-silencing treatment to improve chronic liver disease called MASH, especially in people with certain genetic risk. You may be eligible if you have MASH with moderate-to-advanced scarring and specific test results, and if other liver causes and recent substance/alcohol issues don’t apply.

Lower-dose transplant medicines to prevent graft-versus-host disease
This early-phase study tests a lower dose of cyclophosphamide given after a stem cell transplant to prevent graft-versus-host disease (GVHD). It also uses sirolimus and mycophenolate to improve how well the donor immune system accepts the transplant, aiming to reduce side effects while keeping protection against GVHD.

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.
