Testing hormone shots to protect ovaries during lupus chemotherapy
This study looks at whether a monthly/3-month hormone medicine (a “GnRH shot”) can help protect ovaries in people with lupus who are treated with cyclophosphamide. It also compares this to lupus patients who do not receive the ovarian-protecting shot, using questionnaires to track outcomes.
Bethesda, MarylandAges 18–120 - NCT05568199Recruiting
Study of brain imaging in people with DBS for Parkinson’s
This trial is for adults with Parkinson’s who already have a deep brain stimulation (DBS) device and who can have 7‑Tesla (7T) brain imaging. The study uses the MRI pictures to help researchers learn more about Parkinson’s and how the brain changes with treatment.

Study of brain signaling and distraction in aging adults
This study looks at how a deep brain area helps people focus and ignore distractions as we get older. You may be invited if you’re a healthy adult and can safely complete brain-related testing.
Blacksburg, VirginiaAges 18–75 - NCT05574647Recruiting
Fast prostate MRI and guided biopsy testing for prostate cancer
This study checks whether a faster prostate MRI and image-matching (image-fusion) can better find suspicious spots so doctors can target a biopsy. If you have concerning prostate exam results or PSA blood test results, you may get an MRI and, if something looks suspicious, a biopsy using MRI images.
Southend-on-Sea, EssexAges 18 years+ - NCT05575401Recruiting
Track surgery results in kids getting tonsil removal
This trial looks at how well a specific throat surgery technique works in children who are having their tonsils removed (with or without removing adenoids). It may help improve how doctors choose and perform surgery for safer, better recovery.
Murrieta, CaliforniaAges 3–17 - NCT05575505RecruitingPhase 2
Pentoxifylline added to ulcerative colitis treatment
This trial tests whether adding the medicine pentoxifylline to standard care can help people with ulcerative colitis. It’s designed to see if this combination improves symptoms by changing inflammation.
Al MansurahAges 18–75 - NCT05578300Recruiting
Translating thrombectomy care into real-world practice in Asia-Pacific
This study aims to help endovascular thrombectomy for certain severe strokes work well in everyday hospital care across Asia-Pacific. You may be considered if you’re an adult with a specific type of stroke blocked in a major brain blood vessel.
Linyi, ShandongAges 18 years+ - NCT05581368Recruiting
Study how cannabis affects blood vessels
This trial tests whether regular cannabis use changes how your blood vessels work, compared with people who do not use cannabis. It may help researchers understand potential effects on heart and circulation health.
London, OntarioAges 19–80 - NCT05582837RecruitingPhase 4
Using migraine medicines to treat Meniere’s disease symptoms
This Phase 4 study tests whether migraine-type medications can help people with active or frequent Meniere’s disease. If you have symptoms like inner-ear episodes, the trial may help find a better way to control them.
Orange, CaliforniaAges 25–85 - NCT05584059Recruiting

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.
