Trial Summary
This is a Phase I/II, randomized, double-blind, dose escalation, safety and PK study. The
study will be conducted in approximately 15 sites in the United States. In Part A, up to 42
patients undergoing deceased donor kidney transplantation will participate. Patients will
receive a single IV injection of I5NP or placebo. I5NP (or placebo) will be administered
approximately 30 minutes following reperfusion of the graft (final re-establishment of good
blood flow to the graft) and achievement of hemostasis. The duration of the study is
approximately 180 days.
Eligibility
Inclusion Criteria:
- Patient is at least 18 years of age
- Patient has given informed consent
- Patient is willing to comply with protocol
- Patient is willing to practice birth control for the duration of the study (180 days)
- Women of childbearing potential test negative for pregnancy (either urine or serum)
within 48 hours prior to transplant - Patient is up-to-date on cancer screening according to site-specific guidelines
- Recipient of donor kidney transplant from ECD with brain death, or from DCD, or from
SCD with cold ischemia time (CIT ) > 24 hours - Patient is dialysis dependent at the time of transplant by: a) at least 2 dialysis
sessions/week in the 56 days prior to transplant, or b) removal of remaining nephron
mass at time of transplant, or c) the opinion of the investigator that the patient's
renal function has been permanently eliminated
Exclusion Criteria:
- Patient has participated in an investigational drug study in the last 30 days
- Patient has known allergy or has participated in prior study with siRNA
- Patient is HCV-positive and has liver function tests (ALT, AST or bilirubin) >1.5
ULN; patient plans to receive an HCV-positive kidney - Patient is planned to receive multiorgan transplant
- Patient has a planned transplant of kidneys that are implanted en bloc (dual kidney
transplant) - Patient has planned transplant of kidneys from donors < 6 years of age
- Patient has planned transplant of dual kidneys (from the same donor) transplanted not
en bloc (as in the case of dual ECD donor kidneys) - Patient has a planned transplant of a kidney from a donor who is known to have
received an investigational therapy (under another IND) for ischemic/reperfusion
injury immediately prior to organ recovery - Patient is planned to receive a living donor kidney
- Patient is planned to receive an ABO-incompatible donor kidney
- Patient is planned to receive an organ from a DCD donor that also meets the criteria
for an ECD donor - Patient has history or presence of a medical condition or disease that in the
investigator's assessment would place the patient at an unacceptable risk for study
participation
Detailed Description
The drug (I5NP) is a small interfering RNA that is being developed for the prophylaxis of
delayed graft function (DGF) in patients receiving renal transplants. This study will test
the safety of I5NP and measure how long the drug stays in the blood stream after injection.
Another purpose of this dose escalation study is to find out the right dose of the
experimental drug to be given to study subjects in future studies. Even though there were no
harmful effects seen in the animals tested, we do not know what side effects the
experimental drug might cause in humans.
Important
Final eligibility is determined by the health professionals conducting the trial and the protocol approved by the Committee on Human Resources (CHR) at the University of California, San Francisco (UCSF).
