Lantheus Medical Imaging, Inc. to Present Clinical Data on Investigational Cardiac PET Imaging Agents at American Society of Nuclear Cardiology
N. BILLERICA, Mass. (September 20, 2010) – Lantheus Medical Imaging, Inc., a worldwide leader in diagnostic medical imaging, today announced that seven abstracts related to two of the company’s cardiac Positron Emission Tomography (PET) imaging candidates will be presented at ASNC2010, the 15th Annual Scientific Session of the American Society of Nuclear Cardiology, being held September 23-26, 2010 in Philadelphia. Data being presented include preliminary results from a single site Phase 2 study on flurpiridaz F 18 (formerly known as BMS747158), a myocardial perfusion PET imaging candidate in development to diagnose coronary artery disease, and Phase 1 data on LMI 1195, a novel cardiac neuronal PET imaging candidate. These abstracts will be highlighted in a series of poster presentations at the meeting.
“Lantheus is pleased that seven abstracts will be presented at ASNC2010 highlighting important data on our cardiovascular imaging pipeline candidates,” said Don Kiepert, President and Chief Executive Officer of Lantheus Medical Imaging, Inc. “These data continue to support the potential of PET technology for the diagnosis and evaluation of coronary artery disease and heart failure. We believe that next generation medical imaging tools like flurpiridaz F 18 and LMI 1195 can ultimately provide physicians with improved non-invasive and cost-effective options to evaluate and help manage cardiovascular diseases.”
The schedule and abstract information for the poster presentations are listed below.

About Flurpiridaz F 18 Injection
Flurpiridaz F 18 injection, a fluorine 18-labeled agent that binds to mitochondrial complex 1 (MC-1)1, was designed to be a novel myocardial perfusion PET imaging agent for the diagnosis of coronary artery disease (CAD). The agent is currently in Phase 2 clinical development. CAD is the leading cause of death in the United States for both men and women2. Each year, more than half a million Americans die from CAD2.
In Phase 1 clinical studies, flurpiridaz F 18 injection was well-tolerated and demonstrated radiation dosimetry that suggests that good quality images may be obtained with patient radiation doses that are within accepted limits. The data also showed high myocardial uptake at rest that significantly increased with pharmacologically induced stress as well as a ratio of myocardial to background uptake that was favorable and improved over time, suggesting potential as a myocardial perfusion PET imaging agent for patients both at rest and under stress.
About PET and MPI
Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging procedure3 that provides information about the function and metabolism of the body's organs, unlike computed tomography (CT) or magnetic resonance imaging (MRI), which primarily show anatomy and structure4. Myocardial perfusion imaging (MPI) is a non-invasive test that utilizes a small amount of radioactive material (radiopharmaceutical) injected into the body. The distribution of the radiopharmaceutical is imaged using a scanner, and the resulting images reveal the distribution of blood flow (perfusion) to the heart5. The test is typically conducted under both rest and stress conditions, after which physicians examine and compare the two scans and predict whether the patient has significant coronary artery disease5. Although single-photon emission computer tomography (SPECT) is most commonly used for MPI6, PET imaging has gained considerable support and use in the field of cardiovascular imaging, as it offers many advantages to SPECT, including higher spatial and contrast resolution, which results in higher image quality and improved diagnostic accuracy, accurate attenuation correction and risk stratification information7.
About LMI 1195
LMI 1195 is a novel F-18 tracer designed to use positron emission tomography to improve imaging of cardiac neuronal function. LMI 1195 has completed Phase 1 clinical trials. In preclinical studies, LMI 1195 showed promise as a heart failure imaging agent with high cardiac sympathetic nervous system uptake8.
