Beetroot juice to boost exercise in fibrotic lung disease
This trial tests whether drinking beetroot juice can improve exercise performance in people with fibrotic interstitial lung disease (scarring in the lungs). It may help your body use oxygen better during activity if you meet the study’s safety and lung-function requirements.
Vancouver, British ColumbiaAges 19 years+ - NCT04302870RecruitingPhase 2/Phase 3
Test medicines for motor neurone disease using adaptive trial design
This study tests treatments for motor neurone disease (MND) and assigns people to different treatment arms in an adaptive way. It may help doctors find out which medicine works best and for whom.
Portadown, County ArmaghAges 18 years+ - NCT04312399Recruiting
Hormone treatment study for Alzheimer risk in postmenopausal women
This study looks at whether hormone treatment can help prevent or slow Alzheimer’s disease in women who have gone through menopause. It may help by testing a hormone-based approach in a carefully selected group.
GhentAges 40–65 - NCT04318119Recruiting
Brain scan registry for small blood vessel disease
This study is a registry that collects information and brain scan findings from adults with possible small vessel disease. It may help doctors better understand how this condition looks on scans and what it is linked to.
Fuzhou, FujianAges 18–100 - NCT04320199Recruiting
Fermented beetle powder for alcohol-related liver problems
This trial tests whether a fermented powder made from a specific beetle can improve or protect the liver after alcohol-related liver injury. It’s looking for people with certain liver blood test levels, and it excludes several conditions and recent herbal or liver-affecting treatments.
Pusan, Ami-dongAges 19 years+ - NCT04330846Recruiting
Study of new narrowing in Crohn’s treated with two approaches
This study looks at treatments for a new (de novo) narrow area in the bowel from Crohn’s disease. It aims to see which treatment works better at relieving blockage-type symptoms for the safest, most effective option.
Badalona, BarcelonaAges 18–80 - NCT04335994Recruiting
Home sleep testing for people with memory trouble
This study looks at how well home sleep apnea testing works for people with cognitive impairment (memory/thinking problems) to help improve outcomes. You may be asked to do a home sleep test (and possibly an in-lab test) and will involve a caregiver if needed.
Toronto, OntarioAges Any age - NCT04334031Recruiting
Hospital follow-up study for immune-related disease
This is a study that follows people with an immune-related illness at Lille University Hospital to better understand their care needs over time. By collecting information regularly, the study may help improve how future patients are monitored and treated.
LilleAges 18 years+ - NCT04334707Recruiting
Study kidney damage in people with long-term diabetes
This study is looking at different kidney health patterns in people with diabetes, especially diabetic kidney disease and people who have not developed kidney damage despite long-term diabetes. It may help researchers understand why kidney problems happen—and what protective factors might prevent them.
Tucson, ArizonaAges 18 years+ - NCT04337515Recruiting
Study of a new method to prepare stem cell transplants
This feasibility study tests a technique called CLINIMACS to reduce certain immune cells (alpha/beta T-cells) before a stem cell transplant. It may help make the transplant safer and better controlled, but this is an early-stage feasibility test.
San Francisco, CaliforniaAges Up to 30 years - NCT04340817Recruiting
Study of fatty liver in Nordic countries
This study looks at people with non-alcoholic fatty liver disease (fat buildup in the liver without heavy alcohol use). It may also include healthy volunteers for comparison, helping researchers understand the condition better.
Hvidovre, Capital Region DenmarkAges 18 years+ - NCT04339270RecruitingPhase 4
Testing azithromycin in chronic lung disease with frequent flare-ups
This Phase 4 study tests whether a long course of azithromycin can reduce flare-ups in people with chronic obstructive pulmonary disease (COPD) who have had recent exacerbations. It also looks at mucus properties and how flare-ups happen.
BordeauxAges 40–85 - NCT04344769Recruiting
Studying how a kidney-protecting pathway works in ADPKD
This study looks at how the body’s “Nrf2 response” works in people with autosomal dominant polycystic kidney disease (ADPKD). It may help researchers better understand disease biology and future treatments by comparing kidney-related signals in ADPKD patients and healthy volunteers.

Long-term safety study for ustekinumab vs other biologics
This study follows adults with Crohn’s disease or ulcerative colitis to compare the long-term safety of ustekinumab against other biologic medicines. It may help show how safe these treatments are over time, using medical records.
Portsmouth, VirginiaAges 18 years+ - NCT04371042Recruiting
Study of liver disease and genes in people with fatty liver
This study collects information about metabolic and unexplained (cryptogenic) liver disease and looks at “omics” tests, which are lab tests that measure patterns in blood or tissue to learn what drives the disease. It may help researchers better understand fatty liver and related serious complications, like liver scarring and liver cancer.
Roma, Rome/lazio/italyAges 18 years+ - NCT04375280Recruiting
Study of mobility problems in people with long-term illnesses
This study observes how people with chronic health conditions affect their ability to move and do everyday activities. It may help researchers better understand mobility limits and what factors influence them.

Longer vs shorter abatacept doses to prevent graft-versus-host disease
This trial tests whether giving abatacept for a longer or shorter time can better prevent graft-versus-host disease (a common complication after a stem cell transplant). If you’re having a planned unrelated donor transplant, the results may help reduce the risk or severity of transplant-related immune problems.

Common questions
- Are there clinical trials for disease?
- Yes. Clin2 currently lists 9,578 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.
