SeoulAges 19–84 - NCT07673185Recruiting
Omega-3 and low-dose aspirin for gum disease in smokers
This trial tests whether taking omega-3 supplements with low-dose aspirin can improve gum health in smokers with advanced gum disease (stage III periodontitis). It aims to see if this combination safely reduces gum pocket depth and tissue damage.
CairoAges 30–50 - NCT07652723RecruitingPhase 1
How a new blood-clotting drug affects clotting with and without aspirin
This study tests an experimental drug (BAY3389934) to see how it affects blood clotting and if it's safe. It is given to healthy adults, alone and then with aspirin. It will help researchers understand how the drug works before testing in patients.
Miami, FloridaAges 18–55 - NCT06738992RecruitingPhase 4
Early aspirin after mitral valve repair: safety and effectiveness
This study tests whether starting aspirin early after mitral valve repair is safe and effective compared to standard care. It's for adults who have had this heart surgery and have a low risk of bleeding or stroke.

- Yes. Clin2 currently lists 136 recruiting aspirin 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 aspirin 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 aspirin 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.
