Group 2 names the comparator: placebo.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Regadenoson Arm | 1.44 mcg/kg/hour infused over 48 hours~Regadenoson: Regadenoson is an A2AR agonist that is a coronary vasodilator. It is chemically described as adenosine, 2-\[4-\[(methylamino)carbonyl\]-1H-pyrazol-1-yl\]-, monohydrate. Its molecular formula is C15H18N8O5. Regadenoson has an FDA indication for use in radionuclide myocardial perfusion imaging in patients unable to undergo adequate exercise stress. It has lower affinity for non-A2A adenosine receptor subtypes thought to be associated with some of the adverse effects associated with non-selective adenosine receptor agonists, which increase extracellular adenosine by blocking its uptake into cells. The maximal plasma concentration of regadenoson is achieved within 1 to 4 minutes after injection and parallels the onset of the pharmacodynamic response. Its half-life is approximately 2 to 4 minutes. | 0 | 52 | EG000 |
| Group 2 | Placebo Arm | Placebo infused over 48 hours~Placebo: This study uses 0.9% Normal Saline (NS) as placebo. This is a sterile sodium chloride solution usually used to replenish fluids and electrolytes. It contains no additives, and is a standard solution used as placebo in clinical trials where the study drug is administration intravenously. NS will be prepared by investigational pharmacy. | 0 | 44 | EG001 |
