E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To verify the safety and efficacy of DermaPro® in wounds with impaired healing. Safety is determined by recording local and systemic adverse events as well as by hematology, clinical chemistry and urinalysis. Efficacy is determined by an in-patient comparison of the percent change in area of the wound treated with standard therapy (moist wound dressing containing isotonic sodium chloride solution) plus DermaPro® with the percent change in area of the wound treated with standard therapy alone after 4 weeks of treatment.
|
|
E.2.2 | Secondary objectives of the trial |
•To determine the rate of responding wounds after 4 weeks of treatment with DermaPro® in comparison to the rate of responding wounds treated with standard therapy alone •To determine the relative number of patients with complete wound closure after 12 weeks of treatment with DermaPro® •To determine the relapse rate within 12 weeks after complete wound closure •To determine the wound site pain reduction in the two treatment arms •To determine germ load reduction in the wounds •To determine the efficacy of DermaPro® (after 4 and 12 weeks of treatment) in different wounds regarding size, duration, grade/stage, underlying disease and other characteristics |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
•At least 2 wounds (ulcers) of one of the following types: - venous leg ulcer - mixed (venous/arterial) leg ulcer - diabetic foot ulcer Other wounds with impaired healing, e.g. decubitus ulcer, pure arterial leg ulcer, Charcot's foot or malum perforans, may be present in the same patient but shall not be selected as targets for the present study. •Adequate perfusion of lower leg as determined by the ankle brachial pressure index (>0.5), or by a more precise method (e.g. TcPO2 > 30 mmHg, pelvic/leg angiography) if considered appropriate or necessary by the examining physician to exclude patients who require a revascularization therapy •Presence of the 2 target wounds for 1 month to 3 years without signs of healing •Area of the 2 target wounds between 1 cm2 and 40 cm2 (as measured in mm by multiplying greatest length by greatest width) after debridement (if appropriate) •Wound grade 1 or 2 (according to the Wagner classification) of the 2 target wounds •Presence of at least one of the following underlying diseases confirmed in anamnesis: - chronic venous insufficiency - chronic venous/arterial insufficiency - diabetes •Stationary or ambulant male or postmenopausal female patient between 50 and 85 years of age •General health condition consistent with study requirements as confirmed by anamnesis and physical examination •Written informed consent by the patient for study participation prior to protocol specific procedures
|
