Who cannot join

  • Patient has had cancer or may be predisposed due to a family history of:
  • a clinical syndrome predisposing to malignancy, such as Familial Polyposis Coli, Von Hippel Landau disease (associated with renal cell cancers and renal cysts) and Li-Fraumeni syndrome (associated with inherited mutations of the p53 tumor-suppressor gene)
  • the same malignancy in two or more first- or second-degree relatives

  • 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 < 24 hours prior to surgery
  • In the opinion of the investigator a pre-operative concomitant disease or clinical/laboratory finding that significantly raises the risk of complications in the post-operative period and therefore precludes dosing of the patient
  • In the opinion of the investigator, an intra-operative complication has occurred that significantly raises the risk of complications in the post operative period and therefore precludes dosing of the patient

About this study

Official title: A Phase I, Randomized, Double-Blind, Dose Escalation Trial of the Safety and Pharmacokinetics of a Single Intravenous Injection of I5NP in Patients at High Risk of Acute Kidney Injury Undergoing Major Cardiovascular Surgery

This is a Phase 1, randomized, double-blind, dose escalation, safety and pharmacokinetic study. The study will be conducted in approximately 10 sites in the United States. Up to 48 patients at high risk for AKI (CCF score ≥ 5 OR an estimated GFR (eGFR) <60 mL/min/1.73 m2) who have undergone major cardiovascular surgery will participate. Patients will receive a single IV injection of I5NP or placebo following cardiovascular surgery. I5NP will be administered 4 hours (+/- 30 minutes) following removal of the cardiopulmonary bypass machine (CBM).

The duration of the study is approximately 44 days, inclusive of a 14 day screening period. Patients will be contacted by phone at 6 and 12 months for follow-up questions. Patient visits are screening, day of surgery, hospital in-patient Days 1, 2, 3 - 5 and Day 7 or hospital discharge. Safety follow-up will continue until 30 days post-surgery. 2 phone calls will be made at 6 and 12 months after date of surgery.

Read the detailed description

The drug (I5NP) is a small interfering RNA that is being developed to protect patients from acute kidney injury after cardiac bypass surgery. This study will test the safety of I5NP and measure how long the drug stays in the blood stream after injection. This study is not meant to test if I5NP protects kidneys from the damage that may occur in rare cases during surgery. 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.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing I5NP in people with Acute Renal Failure and Acute Kidney Injury, run by Quark Pharmaceuticals at 10 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 16 Nov 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Lack of an available patient population). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Dose Limiting Toxicities (DLTs) observed among 4 cohorts of 6-12 patients per cohort (time frame: Reviewed at the conclusion of each cohort). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 16 Nov 2010.
