Trial Outcomes & Findings for Caffeine's Effect on Regadenoson Administration With Single Photon Emission Computed Tomography (SPECT) Myocardial Perfusion Imaging (MPI) (NCT NCT00826280)

NCT ID: NCT00826280

Last Updated: 2024-12-03

Results Overview

Each segment of the 17-Segment Model was assessed for radiotracer uptake on a scale of 0 (normal uptake) to 4 (absent uptake). Segments were counted as having a reversible defect if the stress score was greater than the rest score and the stress score was ≥ 2. Change was calculated as the number of reversible defects using regadenoson with caffeine/placebo (Day 5) minus the number of reversible defects using regadenoson alone (Day 3).

PRIMARY outcome

Timeframe: Day 3 and Day 5

Population: The number of participants analyzed represents Full Analysis Set (FAS), which included all randomized subjects with interpretable Myocardial Perfusion Imaging (MPI) scans. The number of participants per arm is consistent for all categories of the data table.

Each segment of the 17-Segment Model was assessed for radiotracer uptake on a scale of 0 (normal uptake) to 4 (absent uptake). Segments were counted as having a reversible defect if the stress score was greater than the rest score and the stress score was ≥ 2. Change was calculated as the number of reversible defects using regadenoson with caffeine/placebo (Day 5) minus the number of reversible defects using regadenoson alone (Day 3).

Timeframe: Day 3 and Day 5

Population: The number of participants analyzed represents Full Analysis Set (FAS), which included all randomized subjects with interpretable MPI scans. The number of participants per arm is consistent for all categories of the data table.

The Summed Difference Score was calculated as the difference in the Summed Stress Score across the 17 segments (scan run under stress condition) minus the Summed Rest Score across the 17 segments (scan run under rest conditions). Change in SDS was calculated as the SDS for regadenoson with caffeine/placebo stress scan (Day 5) minus the SDS for regadenoson only stress scan (Day 3). The full range of the SDS is -68 to 68, where 0 represents no change between Summed Stress Score and Summed Rest Score. A higher positive score indicates more severe coronary artery disease (CAD).
