Bariatric surgery to lower future heart and stroke events
This trial looks at whether weight-loss surgery can reduce the chances of heart attack, stroke, or other serious heart problems in people at higher heart risk. You might be offered surgery and followed over time to see if cardiovascular events are reduced.
Hamilton, OntarioAges 18 years+ - NCT04966481RecruitingPhase 3
Palbociclib plus cetuximab versus cetuximab alone
This trial studies whether adding palbociclib to cetuximab works better than cetuximab by itself for head and neck cancer that is growing again after an anti–PD-1/PD-L1 treatment. It is for people whose tumor has a specific gene change (CDKN2A loss) and who have not had too many prior treatments.
Worthington, MinnesotaAges 18 years+ - NCT05152888RecruitingPhase 4
Testing a cholesterol drug to improve heart blood flow on scans
This trial studies whether lowering LDL (“bad cholesterol”) with a PCSK-9 inhibitor (evolocumab) improves blood flow to the heart, measured by special PET scans. It’s for people over a certain age who have stable coronary artery disease and a higher risk of heart problems.
Boston, MassachusettsAges 50–90 - NCT04297085Recruiting
Study of why blood clots in veins come back
This study follows people who have had a vein blood clot (or related venous clot) to understand what factors may make the clot happen again. It may help clinicians find better ways to prevent repeat clots.
BrestAges Any age - NCT03962920Recruiting
Personalized care for urologic cancer based on gut and urine bacteria
This study looks at how your body’s bacteria (microbiome in and around the urinary/genital area) may help guide personalized treatment for localized urologic cancers. The goal is to see whether tailoring treatment to your bacteria could improve outcomes.
RoskildeAges 40–70 - NCT03770312RecruitingPhase 4
Testing low/moderate statin use to prevent heart problems in older adults
This study looks at whether taking a low- to moderate-dose statin can prevent first-time heart and stroke problems in people age 70 and older. It may help you lower “bad cholesterol” (LDL) and see if that leads to fewer heart events over time.
SeoulAges 70 years+ - NCT03819803RecruitingPhase 3
Fecal transplant for gut graft-versus-host disease
This study tests whether restoring healthy gut bacteria using a fecal microbiota transplant can improve steroid-refractory gut graft-versus-host disease (aGvHD) after stem cell transplant. If your gut symptoms are your first episode and your stool bacteria diversity is low, this trial may be an option worth screening for.
Graz, StyriaAges 18–70 - NCT03901235RecruitingPhase 1/Phase 2
Stem cell injections for Crohn’s lesions that won’t heal
This study tests injections of stem cells placed directly into Crohn’s affected tissue. It may help people whose Crohn’s disease lesions have not responded to standard medicines and biologic therapies.
Liège, LiègeAges 18 years+ - NCT05512754RecruitingPhase 4
Test whether anti-inflammatory medicine helps when PSA is high
This trial studies whether taking anti-inflammatory medicine (ibuprofen or similar “NSAID” drugs) can improve what doctors learn in people whose PSA blood test is higher than expected and who need more prostate testing. It may help reduce unnecessary procedures or improve next-step decisions, but only if you meet safety and eligibility rules.
Chicago, IllinoisAges 18–80 - NCT04150640RecruitingPhase 2
Chemo drug combination for advanced stomach or esophagus cancer
This Phase 2 trial tests whether a combination of chemo drugs (oxaliplatin and liposomal irinotecan) plus trastuzumab works better for people with advanced stomach or esophagus adenocarcinoma that has specific tumor markers (HER2 and PDL1). It may help shrink tumors and improve control of the cancer in people who have not had prior treatment for advanced disease.
Madison, WisconsinAges 18 years+ - NCT04438889Recruiting
Join the Austrian myeloid patient registry
This is a registry study that collects information from people with myeloid blood diseases. It helps researchers better understand these conditions and support future research.
FeldkirchAges 18 years+ - NCT04487314Recruiting
Study of chronic vein disease over time
This study follows people (and certain close family members) to document how chronic vein problems develop and change over time. You would get yearly checkups and ultrasound scans to track the natural course of the condition.
Saint PetersburgAges 10 years+ - NCT04307238Recruiting
Anesthesia types and eye response after planned ENT surgery
This study compares different types of general anesthesia by checking how your pupils (the black part of the eye) respond after surgery. It may help doctors understand which anesthesia options are better for eye-related side effects after planned ear, nose, or throat operations.
Vienna, State of ViennaAges 18–99 - NCT05390892RecruitingPhase 4
Preventing kidney and heart damage in type 2 diabetes
This study tests whether diabetes medicines can help prevent worsening heart and kidney problems in people with type 2 diabetes. You’ll be assigned by chance to one of these medicine types, and your other care will be adjusted for safety.
Huntsville, AlabamaAges 40–80 - NCT04046042Recruiting

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.
