Further study details as provided by Loma Linda University:

Primary Outcome Measures:
  • The Primary Endpoint is the Eradication of the Bio-burden as Measured by a Reduction in Culture Growth to ≤ +2. [ Time Frame: at 28 days post enrollment ]

Secondary Outcome Measures:
  • The Secondary Endpoint Measure is a Reduction on Wound Size. [ Time Frame: 28 days post enrollment ]
    reduction in bioburden as assessed by number of cfu's per cm2 on culture

Enrollment: 7
Study Start Date: December 2005
Study Completion Date: October 2008
Primary Completion Date: October 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Topically applied Nitric Oxide
Topically applied Nitric Oxide for 8 hours daily for 2 weeks.
Drug: Nitric Oxide
Topically applied gaseous nitric oxide at 8 to 10 parts per million, for 8 hours each night for 14 nights.
Other Names:
  • ViaNOx-H
  • gaseous nitric oxide
  • gNO

Detailed Description:

The primary goal of this study is to determine the effects of topically applied gaseous nitric oxide on the bio-burden of chronic non-healing wounds of the lower extremities. Reports will include:

  • Comparisons of the demographics and diagnoses of those patients treated with ViaNOx-H.
  • Tabulation as to the organisms found and the bio-burden as measured by counts (0 to +4).
  • Tabulation of the number and types of adverse events during ViaNOx-H treatment.
  • Comparisons of the response of different organisms to ViaNOx-H treatment.
