• Inclusion Criteria:
• • Male or female 18 years of age and older;

• • Willingness to return for all study visits;
• • Stage II or III pressure ulcer (as per NPUAP Staging Guidelines), present for more than 4 weeks (up to Screening visit), located in the ischial, trochanteric, coccygeal, thoracic or abdominal regions. Lower extremity pressure ulcers, such as heel ulcers, are acceptable provided that diabetic foot ulcers are ruled out if the patient has diabetes. Surface dimensions of ulcer must be between 2 to 64 cm2 inclusive but longest diameter must not exceed 10 cm. Depth must not exceed 5 cm;
• • Wound area has not changed by more than +/- 30% between Screening visit and Week 1/Visit 1 (before treatment).
• Exclusion Criteria:
• • Pressure ulcer present for more than 18 months;
• • The ulcer to be treated is planned for operative debridement;
• • The ulcer has significant necrotic tissue (e.g., more than 20% of the ulcer area);
• • Major uncontrolled medical disorder(s) such as serious cardiovascular, renal, liver or pulmonary disease, lupus, palliative care or sickle cell anemia;
• • Severe or significant hypoalbuminemia (albuminemia \< 30 g/L, and/or pre-albumin \< 5 mg/dL), or hypoproteinemia (proteinemia \< 55g/L);
• • Patient with moderate to severe anemia (Hb \< 90g/L);
• • Patient currently treated for an active malignant disease;
• • Patient with history of malignancy within the wound;
• • Patient with history of radiation therapy to the wound region;
• • Patient with prior diagnosis of active malignant disease who is less than 1 year disease-free;
• • Patient with a known osteomyelitis or active cellulitis;
• • Patients that are immunosuppressed or on high dose chronic steroid use;
• • Patients on systemic corticosteroids (a completion of corticosteroid course at least 30 days prior to study enrolment is required);

• • Patients with ulcers from burns (from exposure to high heat), venous ulcers or diabetic foot ulcers;
• • Concurrent disease or drugs known to induce severe photosensitivity of the skin, such as porphyria;
• • Patient has received biological-based therapy in any wound within 3 months of Screening;
• • Concurrent participation in another clinical trial that involves an investigational drug or device that wound interfere with this study;
• • Previous participation in other interventional wound healing clinical investigation within the 60 days prior to Screening visit.
