| Main Objective: Regadenoson is a medicine that dilates blood vessels within the muscle of the heart, and is currently used to enable doctors to visualise the blood supply to heart tissue. The drug works by stimulating a particular type of receptor found in the heart and blood vessels. In addition to dilating blood vessels and improving blood flow, this particular receptor is also thought to protect cells that are not receiving enough oxygen, such as in the case of severe bleeding following injury. Our research team have a developed an animal model that recreates severe bleeding in trauma. Using this model, we have demonstrated that Regadenoson improves the function of the heart, reduces the severity of shock (reduced blood flow), and lowers the amount of fluid needed in resuscitation. We now wish to carry out a Phase 2a study to test whether the use of Regadenoson in severely injured, bleeding trauma patients can provide similar benefits to patient outcomes. We wish to determine whether Regadenoson ;Secondary Objective: In addition to the above, we wish to explore the following: •Change in lactate from baseline to 2 hours post-dosing •h-FABP level on admission and 24 hours (+/- 12-hours) •24-hour fluid and transfusion requirements •Lactate level at admission and 24 hours post-admission •Blood pressure on admission •MAP on admission •Difference between lowest SBP PH and admission SBP •Number of ACEs (defined as rhythm or, ECG changes when noted by clinical team). •Daily SOFA score for days 1 to 7 •Daily CTCOFR for days 1 to 7 •Total number of vasopressor/inotrope days including vasopressor/inotrope type and dose up to day 28, discharge, or death •Total length of hospital stay up to day 28, discharge, or death •GOS-E at discharge •Total length of critical care stay up to day 28, discharge, or death •Mortality (2-hour, 24-hour, discharge/28-day whichever is sooner);Primary end point(s): Blood lactate level 2 hours post IMP administration.;Timepoint(s) of evaluatio | — |
