Pivotal Trial

Summary

This trial will study whether a common post-heart transplant medication can prevent a condition that narrows heart arteries and leads to graft dysfunction.

Who is the study for?
The AERIAL Trial is for adults who've had a heart transplant and can give informed consent. It's not for those with allergies to aspirin or clopidogrel, recent intracranial hemorrhage, bleeding disorders, very low platelet counts, past aspirin-related stomach issues, need for antiplatelets due to other conditions, allergy to iodine contrast agents, or poor kidney function preventing coronary angiography.
What is being tested?
This trial tests if early use of antiplatelet drugs like aspirin or clopidogrel can prevent artery narrowing after heart transplants compared to a placebo. The goal is to see if this approach could work in a larger study across multiple centers.
What are the potential side effects?
Possible side effects include increased risk of bleeding and bruising more easily due to the blood-thinning properties of both aspirin and clopidogrel. Stomach irritation or ulcers may also occur.
