Lantheus Medical Imaging to Proceed with Flurpiridaz F 18 Phase 3 Clinical Program Based on Interim Analysis of Data from First Phase 3 Study

May 1, 2013 at 5:05 PM EDT

No. BILLERICA, Mass. (May 1, 2013)Lantheus Medical Imaging, Inc., a global leader in developing, manufacturing and distributing innovative diagnostic imaging agents, today announced an important milestone for its Phase 3 flurpiridaz F 18 clinical program. An interim analysis of the first of two Phase 3 studies has met the criteria for completion.

“The interim analysis was an important achievement on the way to bringing this potentially game-changing agent to market,” said Jeff Bailey, President and CEO, Lantheus Medical Imaging.

To date, approximately 900 subjects have been imaged with flurpiridaz F 18. The Phase 2 clinical study for flurpiridaz F 18 established optimal rest and stress protocols and indicated that the agent has a superior profile over single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). The Phase 3 clinical development program includes two trials in approximately 1,400 patients at clinical trial sites in North America and Europe. Both Phase 3 clinical studies have received a Special Protocol Assessment from the U.S. Food and Drug Administration. The primary objective of the Phase 3 clinical program is to assess myocardial perfusion using Positron Emission Tomography (PET) imaging with flurpiridaz F 18 in patients with known or suspected coronary artery disease (CAD). The first of the two Phase 3 studies has passed the interim analysis assessment milestone and should be completed later in the year.

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. 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. MPI is a non-invasive test that utilizes a small amount of radioactive material (radiopharmaceutical) injected into the body to show 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 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.
