The International Contrast Ultrasound Society (ICUS)

WASHINGTON, DC -- The International Contrast Ultrasound Society (ICUS) today applauded the FDA’s
decision to modify the U.S. product label for OPTISON®, an ultrasound contrast agent used to improve
the accuracy of radiation-free ultrasound scans. OPTISON® is marketed by GE Healthcare.

The label change was supported by a Citizen Petition filed by ICUS in October, citing newer scientific
studies showing the superior safety profile of ultrasound contrast agents along with their favorable risk-
benefit ratios. The Citizen Petition, which was granted in part by the FDA last week, also supported
a prior modification of the label for DEFINITY®, an ultrasound contrast agent marketed by Lantheus
Medical Imaging.

Shortages of certain prescription drugs, particularly chemotherapy drugs, have created a public health crises, forcing clinicians to scramble to find life-saving medications for their patients.

In January 2012, legislation was introduced to ensure access to information related to drug shortages to compliment an improved early warning system for the FDA. And more recently, legislation to reauthorize the Prescription Drug User Fee Act (PDUFA) contains a provision to bring critical shortage drugs to market faster via a shortcut for proving manufacturing compliance.

Under the PDUFA legislation, to prevent or alleviate shortages of life-sustaining drugs, the HHS secretary may deem major manufacturing changes in compliance with good manufacturing practices (GMPs) if a drug maker can at least implement adequate interim controls and demonstrate that it has a plan and enough resources to achieve full compliance.

Lantheus Medical Imaging. The drug shortage situation has not been limited to cancer drugs. In an April 13th call with members of the ICUS Board, Lantheus CEO Don Kiepert explained that the manufacturer of DEFINITY®, Ben Venue Laboratories, has been experiencing challenges in meeting production demand for the products they produce, including DEFINITY®. According to Kiepert, BVL has not yet re-started production of DEFINITY®; and DEFINITY® will go on back order from mid-April until the time at which (a) BVL can release new quantities of DEFINITY® or (b) Lantheus’ new contract manufacturer, Jubilant HollisterStier (JHS) can begin commercial production of DEFINITY®.

Lantheus informed members of the ICUS Board that the company expects that at least one and possibly both of their production partners will be manufacturing DEFINITY® during summer, 2012, but that temporary shortages are nevertheless expected to occur.

GE Healthcare. In a May statement to ICUS, GE Healthcare stated that the company secured additional supply of its ultrasound contrast agent, OPTISON®, from their current contract manufacturer, Covidien. Also, in an effort to strengthen their supply chain to make sure stock is available for patient needs, GE announced plans to manufacture OPTISON® internally at its plant in Oslo, Norway.

The ICUS Board believes that access to ultrasound contrast agents is critical to patient care because contrast-enhanced ultrasound imaging provides a safe, reliable, cost-effective and radiation-free option for diagnosing medical abnormalities.

Around 700 international experts met in Vienna to discuss the latest advancements in ultrasound, such as a new technique called real time imaging, and of approximately 200 scientific papers. That was back in 1969 when for the first time physicians and scientists from around the world came together in Austria’s capital to share their knowledge of the use of ultrasound waves in medicine. The success of the meeting led to the founding of the World Federation of Ultrasound in Medicine and Biology, WFUMB, four years later.


New London Family Medical Center has added a new tool that helps enhance the image of the heart.

The hospital’s ultrasound department is using Definity, a contrast agent that improves the image quality of echocardiograms — also known as cardiac ultrasound.

Definity doesn’t contain dye, but rather is made up of tiny micro-bubbles that are biodegradable. When it is injected into a patient’s arm during an ultrasound exam, it passes through the patient’s circulatory system. When the ultrasound probe is placed over the patient’s heart, it reflects ultrasound signals, creating a clearer image of the heart. As the bubbles dissipate, the agent is breathed out of the body a few minutes after it is injected.
