The Purpose of This Study is to Assess Clinical Efficacy and Safety of Berovenal® Intended to Promote Treatment and to Expedite Chronic Diabetic Foot Ulcer Healing

Summary

The goal of this clinical investigation is to evaluate clinical efficacy of medical device Berovenal® intended to promote treatment and to expedite healing of chronic diabetic foot ulcer in male or female subjects aged 18-85 years with diabetes mellitus (type 1 or 2) and with present diabetic foot ulcer by providing moist environment similar to intracellular environment of the damaged tissue. It will also learn about the safety of medical device Berovenal®. The main questions it aims to answer are: * Does medical device Berovenal® lower the size of diabetic foot ulcer? * What medical problems do participants have when using medical device Berovenal®? Researchers will compare medical device Berovenal® to a reference device (device with similar purpose of use). Participants will: * Use medical device Berovenal® or a reference device every day for 8 weeks or to the time point when the diabetic foot is closed * Visit the clinic once every 2 weeks for checkups and tests * Keep a diary of their symptoms and the number of times they use medical device Berovenal® or a reference device

Eligibility

Inclusion Criteria:

  * if applicable, surgically debrided ≥ 7 days prior to Visit 1;
  * at the time of randomisation:
* sized 1 - 25 cm2;
* present for ≥ 14 days;

Exclusion Criteria:

* known contraindication for application of hydrogel dressings, incl. Berovenal® and NU-GEL Hydrogel with Alginate;
* at the time of randomisation - documented reduction in Index ulcer area by \> 20%, as compared to its size at Visit 1;
* Index ulcer primarily caused by a medical condition other than diabetes mellitus;
* inadequate arterial circulation to the foot documented within 28 days prior to Visit 1, or during the screening period:

  * Ankle-brachial Index \< 0.7 or \> 1.3 and/or
  * Toe-brachial Index \< 0.7;
* presence of acute Charcot's neuro-arthropathy, or osteomyelitis, on the affected foot within 3 months prior to Visit 1;
* use of wound dressings that include growth factors, bioengineered tissues, or skin substitutes within 14 days prior to Visit 1, or documented intention to use them during the subject's participation;
* use of any investigational drug(s) or device(s), systemic immunosuppressive treatment (including systemic corticosteroids), or application of topical steroids to the Index ulcer surface, within 28 days prior to Visit 1;
* use of cytotoxic chemotherapy and/or radiotherapy within 6 months prior to Visit 1;
* known history of bone cancer or metastatic disease of the affected limb;
* poor nutritional status;
* presence of an on-going uncontrolled renal, hepatic, cardiovascular or other disease that could pose an additional risk for the participant, or could significantly influence interpretation of the results (as evaluated by the investigator);
* known history of non-compliance and/or presence of any condition(s) seriously compromising the subject's ability to adhere to the procedures required by this Clinical Investigational Plan;
* pregnant or breast-feeding females;
* females of childbearing potential not using an effective method of contraception.
