Subjects with renal failure (defined as creatinine ≥ 2.0 to ≤ 3.4 mg/dL) 2. Subjects with other single organ failure with i. Renal impairment (defined as an increase in creatinine of \> 0.3 mg/dL from either an established prior Baseline level or if applicable, upon admission to hospital if prior level is unavailable; for inclusion, the creatinine level must be raised above normal levels), and/or ii.

Participant flow
Recruitment details
In total, 33 subjects were screened at 14 sites, and 23 subjects were randomized to one of the 4 treatment arms.
Pre-assignment details
23 subjects were randomized but 21 subjects received treatment. 1 subject lost due to death and 1 subject lost due to withdrew of consent. 7 subject of 21 completed the treatment phase (Day 28). 4 of 3 completed the two follow-up phone calls made at Months 3 and 6. 14 subjects discontinued the study early.
