Geneva, Canton of GenevaAges 18–80 - NCT04676828Recruiting
SPECT-guided radiation to avoid healthy lung in lung cancer
This study tests a special imaging-guided radiation plan that aims to treat lung cancer while reducing radiation to healthy lung tissue. It may help lower lung side effects while keeping the cancer treatment focused on tumor areas.
Sydney, New South WalesAges 18 years+ - NCT04641039Recruiting
Study of scar differences after lumbar disc replacement
This study compares how postoperative scars look and behave after certain lumbar disc replacement surgery. It may help doctors choose approaches that reduce excessive scar-related problems after surgery.
Valencia, ValenciaAges 18–50 - NCT04626167RecruitingEarly Phase 1
Testing a bladder transplant done with a kidney transplant
This early-phase study is testing a combined bladder and kidney transplant approach for people whose bladder problems damage the kidneys. The goal is to see if this treatment can improve bladder and kidney outcomes and be done safely.
Rochester, MinnesotaAges 1–60 - NCT04601038RecruitingPhase 2
Testing a stress-blocking drug for early Alzheimer's risk
This study tests a new medication, CORT108297, that may help protect the brain from the harmful effects of stress in people at risk for Alzheimer's disease. It is looking for adults age 55 and older who either have mild memory problems or are healthy but have a family history, APOE4 gene, or memory concerns.
Baltimore, MarylandAges 55 years+ - NCT04645602RecruitingPhase 2
Study of pembrolizumab and lenvatinib for lung papillomas
This early-phase trial tests how well pembrolizumab plus lenvatinib can treat respiratory papillomas that have spread to the lungs. It may help people whose lung disease is caused by human papillomavirus (HPV).
New Haven, ConnecticutAges 18 years+ - NCT04634383Recruiting
Testing a brain-connected implant to help some blind people see
This early safety study tests an implanted device placed in the brain to help people with very limited sight (no or minimal light). It focuses on whether the implant can be safely used and whether it may support vision-related signals over time.
Chicago, IllinoisAges 19–70 - NCT04664634RecruitingPhase 3
Digital treatment for drooling and swallowing in Parkinson’s
This trial tests a smartphone/tablet digital program meant to help with drooling (sialorrhea) and swallowing problems in people with Parkinson’s disease. If you’re eligible, you’ll use the platform during clinic study visits to see whether it can improve symptoms and safety.
Evanston, IllinoisAges 22 years+ - NCT04605263Enrolling by invitation
Deep brain stimulation for Parkinson’s walking and falls
This study tests a brain surgery treatment (deep brain stimulation) to help improve gait problems such as freezing of walking, gait instability, or falls in people with Parkinson’s disease. It may help people whose walking symptoms are not well controlled by levodopa (a common Parkinson’s medicine).
Phoenix, ArizonaAges 18–75 - NCT04408430Recruiting
Valve replacement for severe mitral valve disease in high-risk adults
This trial tests a less-invasive way to treat severe mitral valve problems using a transcatheter valve. It may help people who are too high-risk for standard open-heart mitral surgery by improving symptoms and heart function.
Gilbert, ArizonaAges 18 years+ - NCT04569591Recruiting
Using DDAVP with PET scans to find pituitary tumor source
This study tests whether giving DDAVP before a PET scan can help doctors better locate the pituitary problem in people with Cushing disease. It may help confirm where the ACTH-producing tumor is so surgery can be planned more accurately.
Bethesda, MarylandAges 8–99 - NCT04582903Recruiting
Send-in sample collection study for immune response to respiratory viruses
This study collects sent-in samples to better understand how your immune system responds during a COVID-19–like illness and after you recover. It may help researchers learn why some people get sick and others stay uninfected, and how immune protection works over time.
Rockville, MarylandAges 1 day–99 years - NCT04496895Recruiting
Orange peel drink study for reducing body fat
This trial looks at whether a fermented orange peel product can lower body fat in adults. It may help if you have higher body fat and/or fatty liver, and you meet safety and health limits.
Taipei, TaiwanAges 20–65 - NCT04545112Enrolling by invitation
Testing a new heart bypass graft in people needing multi-vessel CABG
This study tests a new way to connect a bypass graft during heart bypass surgery for people with blocked heart arteries. The goal is to see if the new graft can be safely placed and works well enough to improve outcomes compared with the standard approach.
LeuvenAges 18 years+ - NCT04516057RecruitingPhase 3
Tested medicine nabilone for agitation in Alzheimer’s dementia

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,353 recruiting 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 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 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.
