Recruiting studies
- NCT04805957Enrolling by invitation
Check brain and behavior markers during sulforaphane in autism
This study tests whether “digital biomarkers” (measurable signs from digital devices) change during treatment with sulforaphane, which is found in certain broccoli extracts. It may help researchers better understand which signals track response in young men with autism.
Piscataway, New JerseyAges 13–30 - NCT04635891Recruiting
Study motor function tests in FSHD
This trial studies how well certain physical/movement tests work in people with facioscapulohumeral muscular dystrophy (FSHD). It may help clinicians measure changes more accurately and tailor care over time.
Los Angeles, CaliforniaAges Any age - NCT04499326Recruiting
Improve quality-of-life reporting after defibrillator heart ablation
This study looks at how to better track patients’ quality of life (how you feel and function) after catheter ablation for a dangerous heart rhythm, using questionnaires you complete. It may help the care team understand how to measure patient outcomes more accurately after treatment.
LondonAges 18 years+ - NCT04564989Recruiting
Biomarker study for HPV-related throat cancer outcomes
This observational study checks how well a blood test for HPV DNA (and other tumor genetic markers) predicts outcomes in certain throat cancers. It may help doctors better track the disease and plan treatment, because the trial validates these lab signals against real-world results.
Rochester, MinnesotaAges 18 years+ - NCT04421248RecruitingPhase 4
Testing blood or brain markers in kids with ADHD
This Phase 4 study checks whether certain markers change in the brain/body when children with ADHD take methylphenidate (a stimulant). It also compares these markers with healthy children to better understand ADHD.
Baltimore, MarylandAges 8–12 - NCT04445909Recruiting
Continuous skin carbon dioxide monitoring in heart-lung bypass patients
This study checks whether a sensor placed on the skin can reliably measure carbon dioxide levels in people who need VA-ECMO, a kind of temporary heart-lung support. It aims to help doctors monitor breathing and circulation more accurately while you’re on this support.
ViennaAges 18–90 - NCT04158180Recruiting
Questionnaire study for diastasis recti in adult women
This trial is testing and verifying a Spanish questionnaire about diastasis recti (a separation in the abdominal muscles). It may help by creating a tool that doctors and researchers can use to better understand symptoms and severity.
Plasencia, CáceresAges 18–65 - NCT04139616Recruiting
Testing a planned heart rhythm plan after aortic valve replacement
This study tests an algorithm—a step-by-step plan—for how doctors manage abnormal heart rhythms after transcatheter aortic valve replacement (TAVR). It may help guide safer, more consistent care in the weeks after the procedure.
Québec, QuebecAges 18 years+ - NCT04086329RecruitingPhase 1
Testing an oxygen sensor during exercise in muscle disease
This early (Phase 1) study checks whether a tiny oxygen-sensing device works reliably while people with mitochondrial muscle disease (and some healthy volunteers) ride a stationary bike. The goal is to see if the sensor can measure oxygen use during exercise and help future monitoring or research.
Philadelphia, PennsylvaniaAges 18–65 - NCT03915418Recruiting
Screening sleep problems in children with cerebral palsy
This trial checks a new way to find sleep problems in children with cerebral palsy using connected tools (like devices/apps). It mainly helps by making sleep screening easier and more accurate, so families can get the right next steps sooner.
AngersAges 6–15 - NCT03683680Recruiting
Collecting pleural tissue samples to study mesothelioma markers
This study collects tissue samples (from the lining around the lung) from adults with malignant pleural mesothelioma. Researchers will use these samples to check whether certain test markers can predict how the disease may behave, which could guide treatment decisions in the future.
Boston, MassachusettsAges 18 years+ - NCT02544022Recruiting
Testing and validating pain and symptom questionnaires for NF1
This study checks whether patient surveys (questionnaires) can reliably measure symptoms and pain in people with NF1 who have plexiform neurofibromas. It helps create better tools for tracking how you feel and how treatments may affect quality of life.
Washington D.C., District of ColumbiaAges 5 years+ - NCT02283112Recruiting
Testing how well drug tests work on different samples
This study checks whether lab tests can correctly measure drugs in different types of body samples. If you’re an adult who can consent, you may be able to help validate these testing methods so doctors get more reliable results.
LiverpoolAges 18 years+ - NCT02663362Recruiting
Whole-body MRI and scan method testing
This study tests and checks a new way of using MRI scans (and special scan add-ons) across the whole body. You may be able to help researchers improve the imaging tools and methods for future medical use.
Orlando, FloridaAges 12–89 - NCT01299168Recruiting
Testing kidney transplant biopsy samples for better care
This study looks at kidney biopsy samples from adult kidney transplant recipients to help improve how transplant-related problems are diagnosed and treated. If you need a biopsy for medical reasons, you may be invited to participate.
Birmingham, AlabamaAges 18 years+

Common questions
- Are there clinical trials for validity?
- Yes. Clin2 currently lists 567 recruiting validity 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 validity 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 validity 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.
