Lantheus Medical Imaging to Present Data on Novel PET Cardiac and Heart Failure Imaging Agents at SNM 58th Annual Meeting

Company’s Novel PET Imaging Agents Flurpiridaz F 18 and LMI 1195 to be Featured in Eight
Oral and Poster Presentations

N. BILLERICA, Mass. (June 1, 2011)Lantheus Medical Imaging, Inc., a worldwide leader in diagnostic imaging, today announced that data from the Phase 2 clinical trial for the assessment of myocardial perfusion using Positron Emission Tomography (PET) imaging of flurpiridaz F 18 in patients with suspected or known coronary artery disease (CAD) will be presented in a series of oral and poster presentations at the SNM 58th Annual Meeting, being held June 4-8 in San Antonio. In addition, the Company will be presenting data on LMI 1195, a novel cardiac neuronal PET imaging agent in development to improve the evaluation and management of patients with heart failure.

"We are pleased to present eight poster and oral presentations on our cardiovascular PET imaging pipeline candidates at the SNM annual meeting,” said Don Kiepert, President and Chief Executive Officer of Lantheus Medical Imaging. “In recent years, we have seen considerable growth in the support of PET imaging. Lantheus is committed to advancing our pipeline of next generation diagnostic medical imaging products, and we see great promise in flurpiridaz F 18 and LMI 1195 as novel PET imaging tools for the diagnosis and evaluation of coronary artery disease and heart failure.”

The schedule and abstract information for the presentations are listed below:

This presentation will review the development paradigm for cardiovascular molecular imaging agents focusing on the highlights of each phase from preclinical through the sequential phases of clinical trials. Dr. Washburn will present highlights of the flurpiridaz F 18 and LMI 1195 programs to illustrate the unique challenges of successful translation of imaging agents from preclinical characterization to evaluation in human clinical trials.

Lantheus recently presented full Phase 2 study results for flurpiridaz F 18 at ICNC10 in May in Amsterdam. The findings demonstrated PET myocardial perfusion imaging with flurpiridaz F 18 provided superior image quality, diagnostic certainty and diagnostic performance for detecting CAD compared to single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI), the current standard for the non-invasive detection of CAD. The data also demonstrated a positive safety profile for PET imaging with flurpiridaz F 18.

About Flurpiridaz F 18 Injection and Coronary Artery Disease
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 CAD. PET imaging with flurpiridaz F 18 has the potential to be a new clinical tool for the evaluation of myocardial perfusion that may better evaluate patients with known or suspected CAD in comparison to other non-invasive diagnostic modalities. CAD is the most common form of heart disease, affecting approximately 16.8 million people in the United States2. CAD is the leading cause of death in the United States for both men and women3. Each year more than half a million Americans die from CAD3.

About PET and MPI
Positron Emission Tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging procedure4 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 structure5. Myocardial perfusion imaging (MPI) is a non-invasive test that utilizes a small amount of radioactive material (radiopharmaceutical) injected into the body to depict the distribution of blood flow to the heart. MPI is used to identify areas of reduced blood flow (perfusion) to the heart muscle. 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 disease6. Although single-photon emission computer tomography (SPECT) is most commonly used for MPI7, 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 stratification8.

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 uptake9.
