What is the current status of clinical trials for Regadenoson?
Regadenoson, marketed as Lexiscan, is an adenosis receptor agonist primarily used as a pharmacologic stress agent in myocardial perfusion imaging. As of 2023, three significant clinical trials have been completed or are ongoing:
-
Phase 4 (Post-Marketing Surveillance): Focuses on long-term safety and effectiveness in diverse populations. Results have reaffirmed its safety profile, with adverse event rates comparable to other stress agents.
-
New Investigational Uses: Recent trials have explored its utility in pulmonary hypertension and coronary artery disease beyond current indications. These trials are primarily in Phase 2, with completion dates between 2024 and 2025.
-
Regulatory Approvals: The drug maintains FDA approval, with approvals also in the European Medicines Agency (EMA) markets. Ongoing post-marketing studies continue to expand safety data.
