G-Wound (VZ for Wound Treatment)
Study Details
Study Description
Brief Summary
This is a prospective, randomized, open-label, controlled, exploratory trial that aims to investigate the local skin tolerability of topically administered VZ and to evaluate efficacy and safety parameters associated with improved wound condition and healing

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Group 1 Proximal wound SoC treatment - Distal wound VZ application |
Device: VZ powder (purified clinoptilolite)
VZ powder will be applied topically to the open surface of the verum treatment-assigned wound to cover the entire wound area. Following each VZ application, wounds will be protected by wound dressing (non-adhesive wound dressing (AdapticTM) and conventional protective Mepore® dressing).
Procedure: Standard of care (SoC)
wound cleansing (0.9% saline solution) and wound dressing (non-adhesive wound dressing (AdapticTM) and conventional protective Mepore® dressing) will be applied to the SoC-assigned wound.

Outcome Measures
Primary Outcome Measures
- Local tolerability of IMD [14 days]
Local tolerability of IMD assessed using erythema severity score: a scale from 0 - 4 (0 = no visible reaction, 1 = faint, minimal erythema, 2 = erhythema, 3 = erythema with induration of vesicles, 4 = severe erythema with induration, vesicles or bullae or pustules and/ulceration) with 0 being best and 4 being worst.
Secondary Outcome Measures
- Change in wound size [14 days]
Change in wound size between baseline and End of Treatment (EoT) assessed by photographic analysis
- Wound closure [1 day]
Presence or absence of complete wound closure at End of Treatment (EoT) visit
- Wound healing and condition [14 days]
Wound healing and wound condition parameters assessed as a dichotomous outcome by the investigator
- Histological evaluation [2 days]
Descriptive histological evaluation of wound healing by H&E and Masson trichrome staining as well as by immunostaining against biomarkers of the biopsy specimens obtained at baseline and at EoT
- Investigator's satisfaction on topical applicability [14 days]
Investigator's satisfaction on topical applicability of VZ evaluated via a 5-point Likert scale: a scale from 1 - 5: 5 = extremely satisfied, 4 = very satisfied, 3 = moderately satisfied, 2 = slightly satisfied, 1 = not at all satisfied) with 5 being best and 1 being worst.
- Change in local pain intensity [14 days]
Change in local pain intensity based on the Visual Analogue Scale (VAS) when compared to SoC-treated wounds with a scale from 0-10: 0 - no pain and 10 - worst possible pain.
- Adverse Events and Serious Adverse Events [28 days]
Incidence of treatment-emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
