NMES and whey protein for recovery after aneurysmal brain bleed
This pilot study tests whether a therapy that gently stimulates nerves (NMES) and a whey-protein supplement (HPRO) can improve recovery after an aneurysmal subarachnoid hemorrhage (SAH), a type of bleeding around the brain. Participants are usually treated soon after the bleed and stay in the ICU long enough for the study measures.
Baltimore, MarylandAges 18 years+ - NCT03224949Recruiting
Study comparing fatty liver types and healthy livers
This study compares liver samples and blood tests from people with alcohol-related fatty liver disease, alcohol-related hepatitis, and cirrhosis (including some with liver cancer) against healthy controls. It aims to better tell these liver conditions apart and understand what is different between them.
Cleveland, OhioAges 18–75 - NCT03035097Recruiting
Study of lung illness for people who served in Southwest Asia

Study body fat tissue to learn how it affects metabolism
This study looks at samples of body fat to understand what controls metabolism (how your body uses energy). You may be asked for a fat tissue sample during surgery or through a special biopsy scan, depending on your situation.
Bethesda, MarylandAges 18–90 - NCT02734277Recruiting
Extending a past Type 1 diabetes immune study
This study is for people who already took part in an earlier immune-tolerance program for Type 1 diabetes. It tests whether continuing follow-up and assessments can be done safely and may help learn more about long-term immune effects of treatment.
San Francisco, CaliforniaAges 8–35 - NCT02682667Recruiting
Providing blood samples for cancer immunotherapy research
This study collects and stores blood/tissue samples (called biospecimens) to support immunotherapy research at the cancer center. If you may qualify, your samples help researchers test new immune-based cancer treatments.
Bethesda, MarylandAges 18–120 - NCT02821767Recruiting
Eye disease natural history study
This study observes people with various eye conditions to understand how they progress and to help improve future treatments. It may help you learn more about your condition and contribute to medical knowledge.
Bethesda, MarylandAges 2–100 - NCT02890342Recruiting
Studying Propionic Acidemia, gut bacteria, and body chemistry over time
This study follows people with propionic acidemia to better understand how the body, diet, gut bacteria, and blood chemistry change over time. It may help researchers learn more about the condition and how pregnancy, transplant, and daily life affect health.
Bethesda, MarylandAges 1 month–100 years - NCT02896335RecruitingPhase 2
Palbociclib and pembrolizumab for brain metastases
This study tests two drugs, palbociclib and pembrolizumab, for people whose solid tumors (like breast cancer or melanoma) have spread to the brain. The goal is to see if this combination can shrink or slow the growth of brain tumors that are progressing despite prior treatment.
Boston, MassachusettsAges 18 years+ - NCT02763683Recruiting
Study brain changes in Parkinson-related dementia
This study looks at brain features linked to dementia in people who have Parkinson disease. It may help researchers understand why dementia happens in Parkinson and how it could be detected or treated in the future.
St Louis, MissouriAges 50 years+ - NCT03003572Recruiting
Test an immune marker in primary Sjögren’s disease activity
This study looks at an immune reaction (called anti-Ro/SSA IgE) to see how active primary Sjögren’s disease is. It may help doctors better understand what’s driving symptoms and activity levels over time.
BourgoinAges 18 years+ - NCT02936791Recruiting
Study of early inherited kidney cysts and healthy volunteers
This observational study follows people early in autosomal dominant polycystic kidney disease (ADPKD) and also some healthy volunteers to learn how the kidneys work over time. It may help researchers understand early changes, which could guide future treatments.
Chicago, IllinoisAges 4–35 - NCT02693535RecruitingPhase 2
Targeted drug testing for advanced cancer with tumor gene changes
This trial tests whether FDA-approved targeted drugs can help people with advanced cancer whose tumors have specific gene changes. It aims to match your tumor's unique genetic profile to a drug that may work better for you.
Birmingham, AlabamaAges 12 years+ - NCT02997293Recruiting
Enhanced recovery after colorectal surgery care program
This study looks at whether a structured “enhanced recovery” plan around the time of colorectal surgery improves outcomes. Because it focuses on a specific group of surgeries done at a specific hospital during certain dates, it may be mainly for people whose surgeries match those records.
Little Rock, ArkansasAges 18 years+ - NCT02780297Recruiting
Study of rare stone-causing kidney conditions
This study is for people with certain rare kidney conditions that can cause kidney stones. It aims to learn how these conditions behave over time and may help improve future care.
Birmingham, AlabamaAges Any age - NCT02814396Recruiting
ECG analysis system for heart conditions
This trial uses a new ECG analysis system to better detect heart rhythm problems or other heart diseases. It may help doctors diagnose and treat heart conditions more accurately.
TaipeiAges 20 years+ - NCT02872987Recruiting
Adult blood cancer registry study with stored samples
This study enrolls adults with certain blood cancers to better understand diagnosis, treatment choices, and outcomes. You may also be asked to provide or have tissue/blood samples saved so researchers can study what’s going on in the disease.
GrazAges 18 years+ - NCT02851043Recruiting
Non-invasive monitor to measure breathing
This study tests a device that checks breathing without needles or painful procedures. It may help doctors learn how well breathing can be measured in people with mild breathing problems, or in healthy volunteers.
Wilmington, DelawareAges 11–17 - NCT02945345Recruiting
Test how skin scores change in cutaneous dermatomyositis
This study looks at how well skin symptoms improve in adults with cutaneous dermatomyositis by using a specific skin-scoring tool. The results may help doctors better measure treatment response and guide care.
Philadelphia, PennsylvaniaAges 18 years+ - NCT02851784RecruitingPhase 2/Phase 3
Microwave ablation plus immune cell therapy for liver cancer
This study combines microwave ablation, which uses heat to destroy cancer cells, with immune cell therapy that boosts your body's natural defenses to fight the cancer. It may help people with early-stage liver cancer who cannot have surgery.
Beijing, Beijing MunicipalityAges Any age - NCT02954419Recruiting
Biomarker study in kidney disease caused by IgA
This study looks at lab markers (“biomarkers”) in people with IgA nephropathy, using kidney biopsy tissue. It may help researchers find better ways to understand the disease and tailor future care.

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.
