A Dose Escalation and Safety Study of I5NP in Patients Undergoing Major Cardiovascular Surgery

This is an interventional prevention trial for Injury of Kidney focused on measuring Acute Kidney Injury, Acute Renal Failure Read More

Inclusion Criteria (before surgery):

• Patient age between 21 years and 85 years old
• Patient is capable of giving consent
• Patient is willing and able to comply with the visit schedule and study procedures including post-hospitalization discharge follow-up
• Patient is undergoing non-emergent coronary artery bypass graft (CABG) and/or valve replacement surgery
• Patient has a cumulative score of 0 to 8 on the Cleveland Clinic Foundation (CCF) Acute Kidney Injury (AKI) risk factor scale
• The patient reports that they are up to date and have had normal findings on their age- and sex-appropriate cancer screening, per American Cancer Society guidelines, for breast cancer, cervical cancer, rectal cancer, and prostate cancer. If a patient is not up to date, the relevant screening test must be performed and a normal result documented prior to dosing.

Inclusion Criteria (during surgery):

• Patient must have been on cardiopulmonary bypass machine (CBM)

Inclusion Criteria (after surgery):

• Patient must be in the ICU for dosing to facilitate study procedures including PK blood draws and PK urine sampling

Exclusion Criteria (before surgery):

• Patient has undergone any organ transplant
• Patient who has had cancer or may be predisposed to develop cancers such as those with family history of cancers in multiple relatives {i.e., Familial Polyposis Coli, those with family history of Von Hippel Landau disease (associated with renal cell cancers and renal cysts) and those with family history of Li-Fraumeni syndrome (associated with inherited mutations of the p53 tumor-suppressor gene)}
• Patient has a history of any abnormality on chest X-ray that could represent a malignancy
• Patient has a clinically significantly elevated pancreatic and/or hepatic enzyme level, defined as any grade 2, 3 or 4 value according to the National Cancer Institute (NCI) Common Toxicity Criteria for Adverse Events (CTCAE), version 3.0
• Patient has an underlying medical condition which increases the risk of perioperative complications, such as poorly controlled diabetes mellitus or hypertension or significant chronic obstructive pulmonary disease (COPD)

• Women of childbearing potential are to be excluded from this study. Every female subject is considered of childbearing potential unless she has had sterilization surgery, or is post-menopausal.

  • Women 21-59, post-menopausal is defined as no menses for at least 12 months and an elevated follicle stimulating hormone (FSH) level.
  • Women 60-85, post-menopausal is defined as no menses in at least 12 months.
• Patient has participated in a study of an experimental therapy in the last 30 days
• Patient is currently receiving immunosuppressive therapy [this criterion does NOT apply to topical steroids and inhalation steroids for chronic obstructive pulmonary disease (COPD) and/or asthma]
• Patient requires pre-operative dialysis or is currently on dialysis
• Patient is undergoing aortic aneurism repair
• Pre-operative extracorporeal membrane oxygenation
• Pre-operative tracheotomy, or mechanical ventilation
• Patient has Intra-Arterial Balloon Pump (IABP) or other Left Ventricular Assist Device (LVAD)
• Evidence that patient is experiencing possible AKI prior to surgery, defined as a > 1.5 times increase in serum creatinine from screening to any time prior to surgery
• Baseline serum creatinine > 3.0 mg/dL and/or an estimated GFR of < 30 mL/min/1.73 m2, as calculated by the Modification of Diet in Renal Disease [MDRD] Study equation: eGFR (mL/min/1.73 m2) = [186 x (SCr)] - [1.154 x (Age)] - [0.203 x (0.742 if female or 1.210 if African-American female)] where SCr: serum creatinine in mg/dL and age is in years
• Patient has comfort measures only or do not resuscitate (DNR) status
• Patient is participating in a concurrent interventional study
• Patient has received intravenous contrast material < 48 hours prior to surgery
• In the opinion of the investigator a pre-operative concomitant disease or clinical finding such as an abnormality in clinical lab results, chest X-ray, EKG, or physical examination finding that significantly raises the risk of perioperative complications precludes dosing of the patient

Exclusion Criteria (during surgery):

• Patient on CBM for > 3 hours
• Patient experienced major blood loss (>15 units)
• Use of balloon pump or other LVAD during surgery;
• In the opinion of the investigator, an intra-operative complication precludes dosing of the patient

Exclusion Criteria (2-3 days post-removal of CBM):

• Cardiac Index < 2.1 L/min/m2 (applies only to patients with a Swan-Ganz or other PA catheter)
• Patient has a body temperature ≥ 40 °C
• Use of IABP post-surgery
• Fluid imbalance in excess of 15 liters
• PaO2:FiO2 < 250
• Patient receiving ≥ 3 concurrent vasopressors to maintain hemodynamic stability
• In the opinion of the investigator a post-operative complication precludes dosing of the patient
