Pilot Study of Sodium Nitrite in Resuscitated Cardiac Arrest Patients

This study has been completed.
Sponsor:
Collaborator:
Medic One Foundation
Information provided by (Responsible Party):
Francis Kim, University of Washington
ClinicalTrials.gov Identifier:
NCT01178359
First received: August 6, 2010
Last updated: May 16, 2017
Last verified: May 2017
  Purpose
Despite advances in cardiac arrest resuscitation survival from cardiac arrest is less than 20-30% and new therapies are urgently needed. Sodium nitrite infused during resuscitation from cardiac arrest has recently been shown to improve survival in a mouse model of cardiac arrest and our group is eager to test this hypothesis in a clinical trial. Our overall hypothesis is that an infusion of 2 μmole/kg sodium nitrite during resuscitation will increase the proportion of patients who will survive cardiac arrest. In preparation for a clinical trial, preliminary safety and efficacy data (phase 1) is needed which is the primary goal of this study.

Primary Outcome Measures:
  • Blood pressure [ Time Frame: 2 hour ]
  • nitrite concentration levels in blood [ Time Frame: 2 hour ]

Enrollment: 11
Study Start Date: January 2010
Study Completion Date: April 2016
Primary Completion Date: April 2016 (Final data collection date for primary outcome measure)
Detailed Description:

Sixteen patients will be randomized to receive normal saline (n=5) or doses of IV nitrite (n=11). During the nitrite infusion and for 120 min after the infusion is completed, blood pressure and heart rate will be monitored.

The first 3 patients randomized to receive IV nitrite will receive the lowest dose (1 mg) of IV nitrite and compared to one placebo treated patient. If there is no significant decrease in blood pressure or elevation in heart rate, we will then dose escalate to the 6 mg dose in 4 patients and placebo in two patients. Dose escalation to the highest (14 mg) dose will again be contingent on the absence of significant hypotension or tachycardia in the drug treated patients compared to the pooled (n=3) placebo treated patients. The final block of patients will be randomized to the high nitrite dose (n=4) or placebo (n=2). Final comparisons of all groups will be made to the pooled (n=5) placebo group
