Levetiracetam to prevent seizures in adults with Down syndrome and Alzheimer's
This trial tests if levetiracetam, a seizure medication, can prevent seizures in adults with Down syndrome who also have Alzheimer's disease. It aims to help manage a common complication and improve quality of life.
Granada, AndalusiaAges 40 years+ - NCT07235111Recruiting
Studying biomarkers for neurodegenerative diseases
This study is looking for people with neurodegenerative diseases (like Alzheimer's, Parkinson's, ALS) to help researchers find new markers in the body that could help understand these conditions better and possibly lead to better treatments.
Genoa, GenoaAges 18 years+ - NCT07237685Recruiting
Diabetes and heart artery plaque progression study
This study uses a follow-up CT scan of your heart arteries to see how diabetes-related plaque buildup changes over time. It may help researchers understand how well current diabetes treatments are protecting your heart.

Recovery of albumin after major liver and pancreas surgery
This trial tracks how quickly your albumin (a protein in your blood) returns to normal after major surgery on your liver, pancreas, or bile ducts, to see if that predicts your recovery. It may help doctors understand how you are healing.

Surgery vs stents for heart disease with weak heart pump
This trial compares two ways to restore blood flow to the heart—bypass surgery (CABG) or stents (PCI)—in people whose heart pumps weakly (LVEF 40% or less). It aims to find which method works better for chest pain or recent heart issues.
GroningenAges 18 years+ - NCT07283315RecruitingEarly Phase 1
NK cell therapy for children with autoimmune diseases
This trial tests a new treatment using special NK cells (a type of immune cell) designed to target and calm overactive B cells that cause autoimmune diseases like lupus and kidney inflammation. It may help children whose current treatments aren't working well enough.

RiyadhAges 18 years+ - NCT07301892Recruiting
AI help for rheumatoid arthritis diagnosis
This trial tests whether artificial intelligence (AI) can improve how doctors spot complications in people newly diagnosed with rheumatoid arthritis (RA), a condition that causes joint pain and swelling. The goal is to see if AI can make diagnosis faster and more accurate in real-world hospital settings.

Common questions
- Are there clinical trials for general population (no specific condition or disease)?
- Yes. Clin2 currently lists 10,813 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.
