Recruiting studies
- NCT05237505RecruitingPhase 2
Sleep apnea plus COPD study to check heart and breathing effects
This Phase 2 study looks at the cardiovascular (heart/blood vessel) effects of having both sleep apnea and COPD. It may help doctors better understand who is at risk and how to manage these breathing problems together.
La Jolla, CaliforniaAges 40–79 - NCT05241262RecruitingPhase 1
N-acetylcysteine for people with m.3243A>G and low brain glutathione
This trial tests whether the supplement N-acetylcysteine (NAC) can help people who have the m.3243A>G mitochondrial genetic change and low levels of a brain chemical called glutathione. The study aims to see if raising glutathione in the brain is safe and potentially beneficial for these patients.
New York, New YorkAges 18–80 - NCT05254782Recruiting
Blood test after lung tumor surgery to find hidden disease
This study uses a special blood test to look for tiny traces of lung cancer after surgery. It aims to find “minimal residual disease,” meaning cancer cells that may still be hiding after your tumor is removed.
Toronto, OntarioAges 18 years+ - NCT05233631Enrolling by invitation
Registry for people who had endoscopic ultrasound
This trial is a registry that collects information from people who undergo a procedure called endoscopic ultrasound (also known as EUS) at the study center. It helps doctors understand what care is used and what outcomes happen over time.

Study radiation for early metastatic prostate cancer
This Phase 2 trial tests a radiation-focused approach for people with newly diagnosed (de novo) prostate cancer that has spread to a small number of spots, especially in bone. It aims to see how well the treatment controls the cancer while keeping side effects manageable.
La Jolla, CaliforniaAges 18 years+ - NCT05215171Recruiting
Study breathing and blood changes after 9/11 exposure
This study looks at how breathing problems and blood vessel/heart issues may happen after World Trade Center (WTC) dust exposure. It uses blood samples and breathing tests to understand who may be affected and to compare people with and without WTC-related airway reactivity.
New York, New YorkAges 21–90 - NCT05199454Recruiting
Study how “fat-like” particles affect blood vessel function
This study looks at whether tiny fat-based particles (“adiposomes”) can affect how well your blood vessels work, especially in people with diabetes and higher body weight. You may be asked to do moderate exercise and other study procedures after passing safety checks.
Chicago, IllinoisAges 18–50 - NCT05245136Recruiting
Blood test study for advanced cancer monitoring
This study uses a blood test (liquid biopsy) to look for tumor DNA in patients with advanced cancer. It aims to see if this test can help doctors monitor the cancer and make better treatment decisions.
Augsburg, BavariaAges 18 years+ - NCT05244486Recruiting
RestoreX traction therapy after prostate surgery
This trial studies whether RestoreX penile traction can help preserve erectile function after a prostatectomy (surgery to remove the prostate), especially when nerves are spared. If you qualify, you may be asked to use the device and be followed over time to see how erections change.
Phoenix, ArizonaAges 18 years+ - NCT05227222Recruiting
Device treatment for lung swelling after swimming
This trial tests a specific device to treat a lung condition called swimming-induced pulmonary edema, where fluid collects in the lungs after swimming. It may help people who need quick, acute treatment to get breathing better.
FalunAges 18 years+ - NCT02973633RecruitingEarly Phase 1
Heart failure MRI brain-wave images after heart trouble
This early-phase study uses a special MRI scan to look at the heart in people with heart failure (and related heart changes). It aims to see whether these MRI results can better characterize heart disease and help doctors understand what’s going on.
Charlestown, MassachusettsAges 18–85 - NCT02215928Recruiting
Using tumor genetic tests to guide treatment choices
This study looks at your tumor’s genetic information to help doctors recommend treatment for cancers that have spread. It may help you get the most suitable therapy based on what’s found in your tumor.
Palo Alto, CaliforniaAges 18 years+ - NCT01521741Recruiting
Breast cancer lymphedema screening to detect early swelling
This trial looks at whether scheduled measurements can spot early swelling (lymphedema) in people with breast cancer. It may help find problems sooner so treatment or prevention steps can start earlier.
Boston, MassachusettsAges 18 years+ - NCT04580420RecruitingPhase 2
Study of an oxalate-lowering medicine for PH1 and kidney failure
This Phase 2 study tests a medicine called DCR-PHXC to lower body oxalate levels in people with PH1 who have advanced kidney failure. By lowering oxalate, the treatment may reduce harm from oxalate buildup and help researchers understand safety and effectiveness.
San Francisco, CaliforniaAges Any age - NCT05181826Recruiting
Blood collection study for cancer and benign diseases
This study collects blood samples from people with different health conditions (cancer, diabetes, liver disease, etc.) and from healthy volunteers. The goal is to find markers in the blood that could help detect or monitor diseases.
Redondo Beach, CaliforniaAges 18 years+ - NCT05142800Recruiting
Screening for Lymphedema in Breast Cancer Targeted Therapy
This study is looking at whether targeted therapy for breast cancer changes the risk of arm swelling (lymphedema). It is a screening trial that uses a machine to measure arm size and check for any swelling early on.
Boston, MassachusettsAges 18–80 - NCT05183490RecruitingPhase 1
Cell therapy for repeated viral infections after transplant
This early-phase (Phase 1) study tests an immune cell treatment (R-MVST) to help people whose immune system has been weakened by a past transplant and who keep getting viral infections reactivated or not responding well to standard treatment. It may help your body control viruses like EBV, CMV, adenovirus, or BK virus.
New York, New YorkAges 18 years+ - NCT05152823Enrolling by invitationPhase 1/Phase 2
Gene therapy for IGHMBP2-related nerve conditions

Columbus, OhioAges 2 months–14 years - NCT05139797Recruiting
AI-guided heart ultrasound screening for suspected amyloidosis
This study tests whether an artificial-intelligence system can help decide who should get a special heart workup for a rare disease called cardiac amyloidosis. If you have signs that make doctors suspect this, the AI-guided ultrasound screening may help find it sooner.
Los Angeles, CaliforniaAges 18 years+ - NCT05173714RecruitingPhase 2
Sit Less and Move More program for people with CKD
This Phase 2 study tests a program to help people with chronic kidney disease (CKD) sit less and move more, plus a medication (semaglutide) for those who qualify. It may help improve health and day-to-day activity while monitoring safety closely.

T cell therapy to help prevent COVID-19 after transplant
This Phase 1 trial tests a donated immune-cell treatment (T cells) to help immunocompromised people fight or resist COVID-19 after they recently received a bone marrow or stem cell transplant. It aims to see if the treatment is safe and if it helps the body respond better to the virus.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,548 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.
