Fasting before procedures with GLP-1 meds
This study looks at whether people taking weekly GLP-1 medications (like Ozempic or Wegovy) should follow standard fasting rules or a 24-hour clear liquid diet before a procedure. The goal is to find the safest way to prepare.
Melbourne, VictoriaAges 18 years+ - NCT06843902RecruitingPhase 2
Improving heart blood flow in women with HIV
This study is testing a medication that may help improve blood flow to the heart in women with HIV who also have diabetes, kidney disease, or protein in their urine. You would need to have a heart scan that shows low blood flow and not be taking certain diabetes drugs.
Boston, MassachusettsAges 45–75 - NCT06867471Recruiting
Ketone drink study for kidney disease patients
This study tests if a ketone supplement can reduce protein in urine and protect kidney function in people with chronic kidney disease or polycystic kidney disease. You drink a special supplement and researchers measure how it affects your kidneys.
Herning, JutlandAges 18 years+ - NCT06870942RecruitingPhase 2
Radiation therapy for liver cancer that progresses after first immunotherapy

Common questions
- Are there clinical trials studying S-1?
- Yes. Clin2 currently lists 801 recruiting studies that include S-1, drawn from the U.S. registry and rewritten for real people so you can see what each is testing and who it's for.
- How do I know if I qualify for a S-1 trial?
- Each study lists its own eligibility criteria — rules about condition, age, and prior treatments. On every Clin2 trial page we explain these in plain language and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Is S-1 an approved treatment?
- A drug being studied in a trial may be investigational (still being tested) or already approved and being studied for a new use. Each study page explains what phase it's in. Clin2 does not provide medical advice — talk with your doctor about whether S-1 or a specific trial is right for you.
