Remove Contrast Agent Boxed Warning: ICUS
The International Contrast Ultrasound Society (ICUS) is asking FDA to remove Boxed Warnings from ultrasound contrast agent (UCA) labels “in order to bring the labeling into line with the current body of scientific research, which now clearly demonstrates the favorable safety profile and clinical benefits of these radiation-free diagnostic imaging products.” The group’s petition says that the agency first required Boxed Warnings on UCAs in 2007 following spontaneous reports of serious adverse events (SAEs) that occurred after UCA administration. “However,” it says, “the SAEs were not contemporaneously adjudicated and some were later attributed to underlying medical conditions and/or medication. Since 2007, peer-reviewed publications have consistently shown that UCAs are exceedingly safe, efficacious, and save lives. Indeed, the most current safety data convincingly show that UCAs are among the safest diagnostic imaging products available.
ICUS says Boxed Warnings are appropriate only as an indicator of the very highest level risk associated with FDA-approved products. “This extreme level of risk is simply not presented by the use of UCAs, and ICUS is deeply concerned that the current Boxed Warnings unduly deter the use of UCAs when medically indicated, to the detriment of our patients,” the organization says. It recommends that appropriate warnings should be included in the Warnings and Precautions section of UCA labels, without a black box.
