Substantial evidence exists that maintaining an adequate mean arterial pressure (MAP) is important to outcomes; even a short exposure to hypotension (defined as MAP <?55?mmHg) may lead to increases in complications such as acute kidney injury and myocardial damage (2). The human body leverages three main regulatory systems to maintain blood pressure: the sympathetic nervous system, arginine-vasopressin, and the renin-angiotensin system. Clinicians currently only have two categories of therapeutic agents available for the management of hypotension, specifically catecholamines and vasopressin. Catecholamines and vasopressin are familiar and well-characterized vasopressors, but have significant side effects at high doses. Patients receiving high doses of vasopressors (>?0.2?ug/kg/min of norepinephrine or the equivalent) are at an increased mortality risk of >?50% (3, 4). In order to defend an appropriate MAP, clinicians are often faced with the undesirable trade-off of higher toxicities due to escalating doses of catecholamines or vasopressin. Angiotensin II has been studied previously in only a single randomized controlled trial of 20?patients (ATHOS-1). ATHOS-3 was designed to meet the Food and Drug Administration (FDA) approval requirements of safety and efficacy. A study design in which the MAP target remained 65 to 75 mmHg once angiotensin II was added would have necessitated a reduction in the background vasopressor dose. This reduction in background vasopressor would have offset potential toxicity and not yielded a clear examination of the safety profile of the new agent. Likewise, using an active comparator would not have allowed a clear determination of the vasopressor activity nor a clear determination of the safety of angiotensin II. The placebo-controlled study design in which the MAP was allowed to rise for the first three hours was therefore chosen to clearly define the potency and safety of angiotensin II.The study design built in two major endpoints within the first 48 hours:?The first three hours was a ‘vasopressor’ trial to test the hypothesis that angiotensin II can raise blood pressure in patients with severe vasodilatory shock already on a high dose of background vasopressors. This is important, as available data clearly show that even a short period of hypotension may lead to worse outcomes. The main utility for angiotensin II is as a vasopressor and it was essential to clearly delineate its safety and vasopressor potency.The second phase of the trial was a more typical vasopressor study design wherein a new vasopressor is introduced, the clinical MAP target is maintained, and catecholamines are titrated down to estimate the effect on blood pressure. This portion of the study, which mimicked “realworld” practice, allowed the clinicians to use their clinical judgment regarding how to best leverage three different drugs in the management of hypotension.In summary, the study design allowed for a clear assessment of safety and incorporated two key metrics of a vasopressor performance: capacity to raise blood pressure and a potency assessment as compared with catecholamine dosing. Inclusion and Exclusion Criteria from ATHOS-3 Study ProtocolEach patient must meet all of the following inclusion criteria to be enrolled in the study:Adult patients ≥?18 years of age with catecholamine-resistance hypotension, defined as those who require a total sum catecholamine dose of >?0.2 ?g/kg/min (see Table 1 for conversion to norepinephrine equivalent) for a minimum of 6 hours and a maximum of 48 hours, to MAP between 55 to 70 mmHg. Patients are required to have central venous access and an arterial line present, and these are expected to remain present for at least the initial 48 hours of study.Patients are required to have an indwelling urinary catheter present, and it is expected to remain present for at least the initial 48 hours of study. Patients must have received at least 25 mL/kg of crystalloid or colloid equivalent over the previous 24hour period, and be adequately volume resuscitated in the opinion of the treating investigator.Patients must have clinical features of high-output shock by meeting one of the following criteria:Central venous oxygen saturation (ScvO2) > 70% (either by oximetry catheter or by central venous blood gas) and central venous pressure (CVP) > 8 mmHg. ORCardiac Index > 2.3 L/min/m2.Patient must meet 5a or 5b to be eligible.Patient or legal surrogate is willing and able to provide written informed consent and comply with all protocol requirements.Patients meeting any of the following exclusion criteria are not to be enrolled in the study:Patients who are < 18 years of age.Any patient with burns covering > 20% of total body surface area. Patients with a Cardiovascular Sepsis-related Organ Failure Assessement (SOFA) score ≤ 3.Patients diagnosed with acute occlusive coronary syndrome requiring intervention.Patients on veno-arterial (VA) extracorporeal membrane oxygenations (ECMO).Patients who have been on ECMO for less than 12 hours. Patients in liver failure with a Model for End-Stage Liver Disease (MELD) score of ≥ 30.Patients with a history of asthma or who are currently experiencing bronchospasm requiring the use of inhaled bronchodilators, if not mechanically ventilated. Patients with acute mesenteric ischemia or a history of mesenteric ischemic. Patients with a history of, presence of, or highly-suspected of having an aortic dissection or abdominal aortic aneurysm.Patients requiring more than 500 mg daily of hydrocortisone or equivalent glucocorticoid medication as a standing dose. Patients with Raynaud’s phenomenon, systemic sclerosis ,or vasospastic disease.Patients with an expected lifespan of < 12 hours.Patients with active bleeding AND an anticipated need (within 48 hours of initiation of the study) for transfusion of > 4 units of packed red blood cells.Patients with active bleeding AND hemoglobin < 7g/dL or any other condition that would contraindicate serial blood sampling.Patients with an absolute neutrophil count of < 1000 cells/mm3.Patients with a known allergy to mannitol.Patients who are current participating in another interventional clinical trial.Patients who are known to be pregnant at the time of screening.Supplemental Table 1.
