LEXISCAN (regadenoson)

Adenosine Receptor Agonists Trial Activity: Declining 3 active trials
Cardiovascular Approved 2008-04-10

Lexiscan is a stress agent used for radionuclide myocardial perfusion imaging (MPI) in clinical settings. It helps patients who cannot perform enough physical exercise to complete a traditional stress test. By simulating the effects of exercise on the heart, it allows healthcare providers to conduct necessary cardiac imaging.

How LEXISCAN Works

This medication works by targeting and activating A2A adenosine receptors in the body. Once these receptors are triggered, they cause the coronary arteries to dilate, which increases the volume of blood flowing to the heart.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
