The most common adverse reactions include dyspnea (shortness of breath), headache, angina pectoris (severe pain in the chest), chest pain, fatigue, ST segment changes, flushing, nausea, abdominal pain, dizziness, and arrhythmia (irregular heartbeat).[3]

Flurpiridaz (18F) was approved by the FDA for medical use evaluate for myocardial ischemia and infarction in the United States in September 2024.[3][4][5]

Medical uses

edit

Flurpiridaz (18F) is indicated for positron emission tomography myocardial perfusion imaging under rest or stress (pharmacologic or exercise) in adults with known or suspected coronary artery disease to evaluate for myocardial ischemia and infarction.[2][3]

History

edit

Flurpiridaz F-18 is a fluorine 18-labeled agent developed by Lantheus Medical Imaging for the diagnosis of coronary artery disease.[6]

The efficacy and safety of flurpiridaz (18F) were evaluated in two prospective, multicenter, open-label clinical studies in adults with either suspected CAD (Study 1: NCT03354273) or known or suspected CAD (Study 2: NCT01347710).[3] Study 1 evaluated the sensitivity (ability to designate an imaged patient with disease as positive) and specificity (ability to designate an imaged patient without disease as negative) of flurpiridaz (18F) for the detection of significant CAD in subjects with suspected CAD who were scheduled for invasive coronary angiography (ICA).[3] Across three flurpiridaz (18F) imaging readers, estimates of sensitivity ranged from 74% to 89% and estimates of specificity ranged from 53% to 70% for CAD defined as at least 50% narrowing of an artery.[3]

Study 2 evaluated the sensitivity and specificity of flurpiridaz (18F) for the detection of significant CAD in subjects with known or suspected CAD who had ICA without intervention within 60 days prior to imaging or were scheduled for ICA.[3] Across three flurpiridaz (18F) imaging readers, estimates of sensitivity ranged from 63% to 77% and estimates of specificity ranged from 66% to 86% for CAD defined as at least 50% narrowing of an artery.[3]
