Eligibility Criteria
Inclusion Criteria:
- Males and females ≥ 18 years of age
- Had renal transplantation due to end stage disease requiring chronic dialysis
- Study drug can be administered within 36 hours after transplantation
- Received kidney from healthy donor or donor with history of diabetes mellitus or hypertension
- Donor terminal serum creatinine ≤ 2.2 mg/dL.
- No urine output, OR average urine output of < 50 cc/H over 8 or more consecutive hours, OR normal urine output following transplantation that diminished to average of < 50 cc/H over 8 or more consecutive hours, OR creatinine reduction ratio at 24 hours after transplantation to pre-transplantation is < 30%.

- Recipient of kidney with cold ischemia time > 40 hours
- Has measurable donor-specific antibody or positive cross-match requiring deviation from standard immunosuppressive therapy.
- Currently participating in or has participated in an investigational drug or medical device study within 30 days or five half-lives, whichever is longer, prior to enrollment into this study.
- Concurrent sepsis or active bacterial infection.
- Have an active malignancy or history of solid, metastatic or hematologic malignancy with the exception of basal or squamous cell carcinoma of the skin that has been removed.
- Women of child bearing potential who are breast feeding.

- Subject is unwilling or unable to comply with the protocol or to cooperate fully with the Investigator or the site personnel.
- Subject is not deemed medically stable for the study in the opinion of the Investigator or the subject's primary nephrologist.

5. Study Description
Brief Summary
The objective of the study is to evaluate the safety and activity of a investigational drug in improving renal function in patients who have undergone renal transplantation and have signs and symptoms of significant renal injury and are at risk for dialysis.
Detailed Description
Delayed graft function (DGF) is generally defined as the need for dialysis during the first 7 days after transplantation although the definition can also include failure to improve preexisting renal function. DGF is an important problem in renal allograft transplantation that affects approximately 25% of transplanted cadaveric kidneys. It has generally been observed that delayed graft function has been associated with reduced graft survival. In addition to an association of DGF with graft loss, DGF imposes an economic burden due to prolonged hospitalization and dialysis. The strongest association with occurrence of DGF is ischemia around the time of transplantation. Aside from approaches to minimize ischemia time and use of antibody induction, there are no good specific therapeutic options to prevent or treat delayed graft function. This study is designed to evaluate the safety and activity of an investigational drug in improving renal function in patients who have undergone renal transplantation and have signs and symptoms of significant renal injury and are at risk for dialysis.
