You may be eligible if
1. 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.
2. Eighteen (18) years of age or older, of either sex, and of any race or skin type.
3. Willing and able to make all required study visits.
4. 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.
5. Subject is currently being treated in an in-patient acute care setting.
6. Willing to use an appropriate off-loading device to keep weight off of foot ulcers; currently receiving adequate pressure redistribution according to local protocol in the affected area for pressure ulcers.
7. For DFU: 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 using the ARANZ Silhouette imaging device).
For PU: Stage II-IV ulcer that is 1 cm2 to 64 cm2 inclusive (as measured at the Screening Visit using the ARANZ Silhouette imaging device).
\- Subjects may have more than one ulcer without limitation on the ulcer burden, but only one qualifying ulcer per subject will be selected for the study (selection based on greatest clinical need, as determined by the Investigator).
8. For lower extremity ulcers: Adequate arterial blood flow as evidenced by an ankle brachial index (ABI) of \> 0.70 and ≤ 1.2. If ABI \> 1.2, perfusion at or near the site of the ulcer must be confirmed: i.e., the foot is warm to the touch and has palpable pulses. Availability of an ABI completed within the 90 days of Screening is acceptable.
9. Separation of at least 5 cm (closest ulcer edge to other closest ulcer edge) as measured using the ARANZ Silhouette imaging device if ≥ 2 ulcers are present.
10. Target ulcer is not infected based on clinical assessment.
You may not be if
1. Contraindications or hypersensitivity to the use of clostridial collagenase.
2. Participation in another clinical trial within thirty (30) days of Screening, or planned participation overlapping with this study.
3. Bleeding disorder that would preclude sharp debridement during the study.
4. Active cellulitis of the target ulcer, lymphangitic streaking, deep tissue abscess, or infection of muscle, tendon, joint or bone.
5. Co-morbidities leading to systemic organ dysfunction or severe single- or multi-organ failure that in the opinion of the Investigator would preclude safe subject participation in the study.
6. A target ulcer which involves the underlying tissues of tendon.
7. Diagnosis of chronic granulomatous disease, leukocyte adhesion defects, or severe neutropenia.
8. 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 for acute wound-related infection
* Topical antibiotic treatment of the target ulcer
9. Treatment of target ulcer with bioactive therapies within 1 month of screening:
