Study summary

To determine the effects of topically applied ViaNOx-H for 8 hours daily for 2 weeks on the reduction of the bio-burden in biofilms on chronic non-healing wounds as recorded by measurements of wound size and wound culture.

Read the 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.
