 (submitted: July 29, 2020)
To evaluate and compare the efficacy of a single 3.0 mg/kg infusion of suramin versus placebo in subjects with diuretic unresponsive AKI [ Time Frame: 7 days ]
The difference between the effect of a 3.0 mg/kg infusion of suramin versus placebo will be based on meeting 2 or more of the composite event endpoints of: peak serum creatinine (Cr) of 6 mg/dL or above from investigational product (IP) infusion through Day or progression to KDIGO Stage III within 72 hours (hr) from IP infusion or death or dialysis from IP infusion through Day 7.
