  Purpose

Researchers at LSUHSC-S hope to learn the effects of the combination of a medication and a device which by themselves are effective for the treatment of wounds.

You are being asked to take part in this study because you have a wound on your body which has not responded to standard treatments.

The researchers will be studying whether the combination of two treatments will make wounds heal faster. For those in study, the investigators will treat them with a vacuum device on their wound. Also, some of the people in the study will receive a special ointment and researchers will use special tests to determine if the two treatments together are working better than just one treatment alone.

Primary Outcome Measures:
  • A significant reduction in the presence and quantity of chronic inflammatory cells in patients receiving Collagenase and Negative Pressure Wound Therapy (NPWT) (vs. NPWT alone) [ Time Frame: 2 weeks into study ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • More robust granulation tissue formation (vs. treatment with NPWT alone) [ Time Frame: 2 weeks into study ] [ Designated as safety issue: No ]

Estimated Enrollment: 50
Study Start Date: June 2010
Estimated Study Completion Date: March 2012
Estimated Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Negative pressure wound therapy
NPWT alone for treatment of pressure ulcer
Device: NPWT - VAC
Vacuum Assisted Closure at 125 mm of negative pressure continuous, dressing changed three times weekly
Other Names:
  • VAC
  • NPWT
Experimental: Santyl Ointment and NPWT
Enzymatic debriding ointment used in conjunction with negative pressure wound therapy
Drug: Collagenase Santyl
Topical enzyme applied to wound tissue
Other Names:
  • VAC
  • Santyl
  • Collagenase

Detailed Description:

Evaluate the effectiveness of Collagenase Santyl ointment when used in conjunction with NPWT for the treatment of chronic pressure ulcers and determine whether the addition of Collagenase Santyl ointment has a positive effect on wound healing. Through volumetric changes and histological evaluation, we wish to test the hypothesis that the application of Collagenase Santyl ointment in conjunction with NPWT facilitates improved wound healing and mitigates some potentially harmful effects of NPWT alone (e.g. pain with dressing removal and tissue ingrowth
