Lantheus to Present New Data on the Effectiveness of Novel PET Cardiac Imaging Agent Flurpiridaz F 18 in Women with Suspected Heart Disease at the American Heart Association 2015 Scientific Sessions

NORTH BILLERICA, Mass.--(BUSINESS WIRE)--Nov. 2, 2015-- Lantheus Holdings, Inc. (the “Company”) (NASDAQ: LNTH), the parent company of Lantheus Medical Imaging, Inc. (“LMI”), a global leader in developing, manufacturing, selling and distributing innovative diagnostic imaging agents and products, today announced that data from a sub-analysis of its first Phase 3 study of flurpiridaz F 18 for myocardial perfusion imaging (MPI) will be presented at the American Heart Association 2015 Scientific Sessions, being held November 7-11, 2015 in Orlando, Florida. Flurpiridaz F 18 is an investigational positron emission tomography (PET) MPI agent in Phase 3 development.

The poster (#4424), “Improved Assessment of CAD in Women with Flurpiridaz F 18 PET Myocardial Perfusion Imaging: A Subset Analysis of the Flurpiridaz F 18 301 Phase 3 Study,” will be presented by Gary V. Heller, M.D., of Morristown Medical Center on Sunday, November 8, 2015 at 2:00-3:15 p.m. EST in the Nuclear Cardiology: Advances in SPECT and PET Imaging session of the meeting.

The data are from a multicenter, international (United States, Canada, and Finland) Phase 3 study designed to evaluate the diagnostic efficacy of flurpiridaz F 18 PET MPI, compared with single photon emission computed tomography (SPECT) MPI in the detection of significant coronary artery disease. Approximately 800 patients with known or suspected CAD who were either scheduled for or had completed invasive coronary angiography (without intervention) were enrolled in the trial. The subset analysis focused on the female sub-population.

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 that may better evaluate patients with known or suspected CAD, which is the most common form of heart disease2, affecting an estimated 15.4 million Americans 20 years of age or older3. CAD is the leading cause of death in the United States for both men and women2. Each year more than 400,000 Americans die from CAD2. Despite increases in awareness over the past decade, only 54% of women recognize that heart disease is their number one killer, accounting for one in every four female deaths4. Heart disease and related risk factors are often missed in women and symptoms of coronary artery disease are often different in women than their male counterparts5. In the first phase 3 study, flurpiridaz F 18 demonstrated improved CAD detection and reduced radiation exposure in women over standard SPECT MPI.

About PET and MPI
Positron emission tomography, also called PET imaging or a PET scan, is a type of nuclear medicine imaging procedure6 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 structure7. MPI is a minimally 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 disease8. Although SPECT is most commonly used for MPI9, 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 stratification10.
