NCT02111291

Brief Summary

The current trial examines the potential benefits of continuous 12 week treatment with Santyl, measured in terms of wound bed appearance. The visual appearance of granulation tissue will be recorded at each visit for the purpose of examining the relationship between wound bed appearance and progress towards healing. In support of this longer treatment regimen with Santyl, a recent animal study found that application of Santyl for 12 weeks was safe and well tolerated. Therefore, the present study is designed to test the hypothesis that daily treatment of diabetic foot ulcers (DFU) with Santyl for up to 12 weeks will result in more rapid development of granulation tissue than DFU treated with supportive care.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Subjects will be considered qualified for enrollment if they meet the following criteria:
  • Provide written informed consent, which will consist of reading, signing, and dating the informed consent document after the Investigator, sub-Investigator or other designated study staff member has explained the study procedures, risks, and contact information.
  • Eighteen (18) years of age or older, of either sex, and of any race or skin type provided that their skin color, in the opinion of the Investigator, will not interfere with the study assessments.
  • Willing and able to make all required study visits.
  • Able to follow instructions and perform the dressing changes at home or have a caregiver who can perform the dressing changes according to the protocol.
  • Willing to use an appropriate off-loading device whenever necessary to keep weight off of any foot ulcers.
  • An ulcer present on any part of the plantar surface of the foot or plantar surface of the hallux which is 0.5 cm2 - 10 cm2 inclusive (as measured at the Screening Visit) with a duration ≥ 6 weeks but not more than 52 weeks (12 months) documented in the patient's history or by patient report of onset which requires debridement.
  • Adequate arterial blood flow as evidenced by an ankle brachial index (ABI) of \> 0.70 and ≤ 1.20. If ABI \> 1.2, perfusion at or near the site of the ulcer should be confirmed; the foot is warm to the touch and has palpable pulses.
  • Separation of at least 5 cm (closest ulcer edge to other closest ulcer edge) if ≥ 2 ulcers are present.
  • Diabetes mellitus (Type 1 or 2) requiring insulin or oral/injectable medications to control blood glucose levels.
  • Target ulcer is not infected based on clinical assessment.

You may not qualify if:

  • Any one (1) of the following criteria will disqualify a potential Subject from participation in the study.
  • Contraindications or hypersensitivity to the use of clostridial collagenase or hydrogel.
  • Undergoing therapy with another investigational agent within thirty (30) days of Visit 1, or planned participation overlapping with this study.
  • Bleeding disorder that would preclude sharp debridement during the study.
  • Active cellulitis of the target ulcer, lymphangitic streaking, deep tissue abscess, gangrene, or infection of muscle, tendon, joint or bone.
  • Infection with systemic toxicity or metabolic instability (e.g., fever, chills, tachycardia, hypotension, confusion, vomiting, leukocytosis, acidosis, severe hyperglycemia, azotemia).
  • A target ulcer which involves the underlying tissues of tendon, muscle, or bone.
  • Diagnosis of chronic granulomatous disease, leukocyte adhesion defects, or severe neutropenia.
  • Current treatment (at the time of the Screening Visit) with any of the following:
  • Systemic corticosteroids. If corticosteroid treatment was for ≥ 10 days, there must be a 1 week interval between discontinuation and screening.
  • Immunosuppressive agents
  • Chemotherapeutic agents
  • Antiviral agents
  • Systemic antibiotic therapy or topical antibiotic treatment of the target ulcer
  • Treatment of target ulcer with bioactive therapies within 1 month of screening:
  • +21 more criteria
