Brief Summary:
Safety and efficacy study of SANGUINATE on reduction of delayed graft function (DGF) in patients who will be recipients of a donation after brain death (DBD) donor kidney.

Condition or disease Intervention/treatment Phase
Delayed Function of Renal Transplant Drug: SANGUINATE Drug: Normal Saline Phase 2

Detailed Description:
Sixty (60) adult subjects who will be recipients of a donation after brain death (DBD) donor kidney and who meet all eligibility criteria will be randomized 1:1 within 48 hours prior to transplant surgery to receive: two infusions of SANGUINATE at a dose of 320 mg/kg or placebo on the day of surgery and approximately 24 hours after surgery. Patients will be hospitalized for up to 5 days and the study duration will be 30 days.

Arm Intervention/treatment
Experimental: SANGUINATE
Two (2) infusions of SANGUINATE
Drug: SANGUINATE
Two (2) infusions of 320 mg/kg of SANGUINATE at Baseline and Day 1
Other Name: pegylated carboxyhemoglobin bovine

Placebo Comparator: Normal Saline
Two (2) infusions of Normal Saline
Drug: Normal Saline
Two (2) infusions of Normal Saline at an equal volume to SANGUINATE at Baseline and Day 1.




Primary Outcome Measures :
  1. Reduction of delayed graft function (DGF) [ Time Frame: 30 Days ]
    Reduction of delayed draft function will be measured by the number of dialysis sessions.

  2. Participants With at Least One Occurrence of Safety Composite Endpoint by Treatment Group. [ Time Frame: 30 Days ]
    Composite endpoint defined by changes in vital signs, electrocardiographic, biochemical, hematological, and urinalysis, graft loss, death and other reported adverse events and Graft Survival - 30 Days


Secondary Outcome Measures :
  1. Proportion of subjects requiring dialysis for any reason in the first 7 days post-transplant [ Time Frame: 7 Days ]
  2. Proportion of subjects requiring dialysis only in the first 5 days post-transplant [ Time Frame: 5 Days ]
  3. Number of days of dialysis therapy. [ Time Frame: 30 Days ]
  4. Proportion of subjects with a fall in serum creatinine. [ Time Frame: 7 Days ]
  5. Proportion of subjects with a serum creatinine greater than 3 mg/dL, but who did not require dialysis by Day 5 post-transplant [ Time Frame: 5 Days ]
  6. Change in estimated creatinine clearance before and after kidney transplantation. [ Time Frame: 30 Days ]
  7. Change in estimated glomerular filtration rate before and after kidney transplantation. [ Time Frame: 30 Days ]

  7. A calculated prediction of DGF risk of least 25%.
  8. Females of childbearing potential must agree to use 2 forms of effective birth control regimen (at least one-barrier method) during the initial 30-day study period.
  9. Male subjects must agree to use condoms or other suitable means of pregnancy prevention.

Exclusion Criteria:

  1. Has received a blood transfusion of packed red blood cells (PRBC), other than with leukocyte-poor blood, within the 90-day period prior to screening.
  2. Recipient of a live donor kidney or a kidney from a donation after cardiac death (DCD) donor.
  3. Recipient of donor kidney preserved with normothermic machine perfusion.
  4. Is scheduled to undergo multi-organ transplantation.
  5. Has planned transplant of kidney(s) from a donor < 6 years of age.
  6. Has planned transplant of kidneys that are implanted en bloc (dual kidney transplant).
  7. Has planned transplant of dual kidneys (from the same donor) transplanted not en bloc.
  8. Body Mass Index (BMI) > 38 kg/m2
  9. Machine perfused preservation donor kidney.
  10. Is scheduled for transplantation of a kidney from a donor who is known to have received an investigational therapy (under another Investigational New Drug) for ischemic/reperfusion injury immediately prior to organ recovery.
  11. Is scheduled to receive an blood type-incompatible donor kidney.
  12. Has undergone desensitization to remove antibodies prior to transplantation.
  13. Total bilirubin > 1.5 mg per dL, transaminase more than twice the upper limit of normal or evidence of hepatic insufficiency
  14. Has participated in an investigational study within the last 30 days or received an investigational product within 5 half-lives of the study drug administration, whichever is longest. Potential subjects participating in a strictly observational study or a study involving approved treatments should be discussed with the Medical Monitor.
  15. Has a history of human immunodeficiency virus (HIV)
  16. History or presence of active substance abuse (illicit drugs or alcohol) in the previous 6 months, as believed by the Investigator
