Primary Outcome Measures:
  • Time to Complete Wound Closure Collagenase Santyl and Vehicle [ Time Frame: 21 days ]

Secondary Outcome Measures:
  • Differences in Scar Viscoelasticity Between Wounds Treated With Collagenase Santyl and Its Vehicle [ Time Frame: 9 Months ]

Arms Assigned Interventions
Experimental: Collagenase Santyl Rate of Wound Closure
Dermatome-induced skin wounds treated with drug active (collagenase).
Drug: Collagenase Santyl

Dermatome-induced skin wounds treated with drug active.

Each subject serves as his own control receiving both treatments in parallel.

Placebo Comparator: Vehicle Rate of Wound Closure
Dermatome-induced skin wounds treated with Vehicle alone.
Drug: Collagenase Santyl Vehicle
Dermatome-induced skin wounds treated with Vehicle alone. Each subject serves as his own control receiving both treatments in parallel.


Ages Eligible for Study:   18 Years to 50 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  1. Provide written informed consent
  2. Willing to attend all required study visits

Exclusion Criteria:

  1. Known hypersensitivity to Clostridial collagenase
  2. Anticoagulants (blood thinners, including aspirin) within two weeks
  3. Congenital skin disorder which affects keratinocytes, elastin, or collagen
  4. Any dermatologic disease which may be aggravated or provoked by the wounding procedure
  5. Dark skin pigmentation to a degree which is very likely to obscure the assessment of vascularization post-wounding
  6. At risk of keloid or hypertrophic scar formation
  7. Scars, tattoos or deformities (i.e., contractures) on the inner aspect of the upper arm area where the wound will be placed
  8. Any skin disorder which causes delayed healing
  9. Disrupted lymphatic drainage of the arm to be studied, or previously diagnosed thoracic outlet syndrome
  10. Taking concomitant medications at doses which are known to interfere with healing, such as non-steroidal anti-inflammatory drugs, anti-neoplastic drugs, or immunosuppressive drugs
