4. Subjects with any known coagulation disorder

5. Subjects who have pigmented skin (Fitzpatrick Classification Level V - VI) due to an increased susceptibility to hypertrophic and keloid scarring

6. History of wound healing abnormalities or a medical condition that is known to be associated with abnormal wound healing

7. Chronic inflammatory dermatological disease

8. History of chronic autoimmune diseases such as, but not restricted to rheumatoid arthritis, inflammatory bowel disease, lupus erythematodes

9. Subjects diagnosed with Diabetes Type I or II

10. Lack of 2-point discrimination above 10 cm as assessed using an aesthesiometer

11. Tattoos, scars, burns, rashes or hyper- or hypopigmentation in the region of planned punch biopsy

12. Evidence of active infectious disease including HIV and hepatitis B or C

13. Current smoker (or any kind of nicotine consumption)

14. Known allergies to biopsy numbing medication, wound cleansing solution and wound dressing

15. Known hypersensitivity to aluminium and/or silicon

16. Allergy requiring medical treatment within the last 4 weeks prior to screening

17. Active infection or fever > 38°C within the last 7 days prior to randomization

18. Clinically relevant abnormalities in the laboratory testing, vital signs, ECG or physical examination

19. Alcohol abuse or a positive urine screen for drugs of abuse at screening

20. Participation in another clinical trial with an investigational day within the last 4 weeks before study participation

21. Employee at the study site, spouse/partner or relative of any study staff (e.g. investigator, sub-investigators, or study nurse) or relationship to the sponsor

• Wound Heal
• Wounds
• Wounds and Injuries

Intervention

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

Type	Measure	Description	Time frame	Safety issue
Primary	Local tolerability of IMD	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.	14 days
Secondary	Change in wound size	Change in wound size between baseline and End of Treatment (EoT) assessed by photographic analysis	14 days
Secondary	Wound closure	Presence or absence of complete wound closure at End of Treatment (EoT) visit	1 day
Secondary	Wound healing and condition	Wound healing and wound condition parameters assessed as a dichotomous outcome by the investigator	14 days
Secondary	Histological evaluation	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	2 days
Secondary	Investigator's satisfaction on topical applicability	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.	14 days
Secondary	Change in local pain intensity	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.	14 days
Secondary	Adverse Events and Serious Adverse Events	Incidence of treatment-emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)	28 days
