Development of 1-Day Rest/Stress Cardiac PET Perfusion Imaging Protocol of BMS747158

A Phase 2, Open-Label, Randomized Multicenter Study for the Development of One-Day Rest/Stress Cardiac Positron Emission Tomography (PET) Perfusion Imaging Protocols of BMS747158

The main purpose of this study is to get more information on using BMS747158 (the study drug),a drug with small amounts of radioactivity to allow for heart imaging, during a PET scan which can then be compared to other images such as SPECT. The safety and quality of images will be studied.

The primary objectives of this study are:

• To acquire data for the development of one-day rest/stress cardiac PET perfusion imaging protocols for BMS747158 with comparable diagnostic image quality to a two-day rest/stress PET protocol
• To assess the safety of multiple doses of BMS747158

The secondary objectives of this study are:

• To assess PET imaging parameters and image quality following administration of BMS747158 at rest and at stress (pharmacologic or exercise) same day (at different time intervals) and 16-48 hours after the rest injection
• To assess feasibility of gated cardiac PET imaging with BMS747158 for left ventricular function assessment
• To assess agreement of one and two day rest/stress PET imaging with BMS747158 in patients with reversible ischemia with rest/stress single photon emission computed tomography (SPECT) imaging
• To perform a preliminary assessment of the diagnostic accuracy of one-day and two-day rest/stress PET perfusion imaging with BMS747158 as compared with invasive coronary angiography or computed tomography angiography (CTA) for detection of
