1. Patient is between 18 and 80 years of age
2. Patients with Type I or Type II diabetes with a glycosylated hemoglobin (HbA1c) of = 12%, obtained at enrollment or within 30 days prior to study enrollment
3. Patients who have a wound defined as diabetic foot ulcer present for = 4 weeks
4. Foot ulcer Wagner grade I– II or ARMSTRONG grade I-A (superficial, non-infected, non-ischemic wound not involving tendon, capsules, or bone) or II-A (non-infected, non-ischemic wound penetrating to tendon or capsule but not to the bone or joint)
5. Estimated foot ulcer surface area between = 0.8 cm2 and = 8 cm2 as
measured at day of randomization assessed using the eKare imaging and
measurement device
6. A patient with more than one diabetic foot ulcer may be included in the study but only one ulcer will be selected for the investigational treatment based on Investigator judgment as far as the ulcer meets the inclusion criteria (the largest ulcer fitting the inclusion criteria will be selected as index ulcer)
7. Wound area has not changed by more than 30 % between screening visit and randomization visit (at least 14 days)
8. Adequate arterial blood perfusion measured on the leg with treated
wound (ABI [ankle brachial index] =0.5 [the lowest ABI measured value
will be used as reference], or toe pressure > 40 mmHg, or tcPO2 > 40
mmHg) within the past 6 months including patients with mild to
moderate peripheral arterial disease (Fontaine Stage I and II)
9. Patient must adhere to off-loading of the ulcer area (in mobile patients adherence to off-loading footwear during the study is mandatory)
10. Patient is able to give written informed consent prior to study start and to comply with the study requirements
11. Women of childbearing potential agree using adequate birth control methods during the study
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 66
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 66
1. History of anaphylaxis, known hypersensitivity to sodium alginate, propylene glycol, methylene-blue or chicken-egg
2. Target ulcer is over a deformity (such as Charcot deformity) that interferes with off-loading based on investigator's opinion
3. Index wound duration of > 3 years without intermittent healing
4. Clinical evidence of ulcer bed infection or patients requiring intravenous (IV) antibiotics to treat the index wound infection at time of randomization
5. Current evidence of osteomyelitis, cellulitis, or other evidence of
infection including pus drainage from the wound site, or documented
history of osteomyelitis at the target wound location during the 8 weeks
preceding the screening visit
6. Major uncontrolled medical disorder(s) such as severe uncontrolled leg edema, concurrent medication, or other issue that renders the patient unsuitable for participation in the study, including but not limited to: comorbid condition with an estimated life expectancy of = 12 months, hemoglobin A1c (Hba1c) > 12% at screening, patients on dialysis, patients with severe pulmonary (requiring home oxygen, uncontrolled COPD Gold III/ IV) or cardiovascular conditions (heart failure NYHA IV, uncontrolled hypertension systolic BP by repeated measurement > 180mmHg)
7. Raynaud disease or any other severe peripheral microvascular
disease, current diagnosis of vasculitis
7a. Patients with PAD who
- have not been assessed by vascular imaging as per standard of care or
- have acute peripheral artery occlusion of the index extremity or
- have PAD Fontaine Stage III and IV or
- have PAD with planned revascularization during the upcoming 6
months or
- had Angioplasty for re-perfusion in the lower extremity with target
ulcer during 3 months preceding the screening visit
8. Dermatologic comorbid disease (e.g. pyoderma gangrenosum, vasculopathy or vasculitic ulcers), history of Systemic Lupus Erythematosus with elevated anti-DNA antibody titers, Buerger’s disease (thromboangiitis obliterans)
9. Patient currently treated for an active malignant disease or prior diagnosis of an active malignant disease who is disease free for less than 1 year. Treatment with anticancer therapy (chemotherapy, immunotherapy, radiotherapy, targeted therapy or gene therapy) within 3 months before the first administration of investigational product or at any time during the study.
10. Patient with history of malignancy within the wound; history of radiation therapy to the wound region
11. Patients who have undergone wound treatments with growth factors, dermal substitutes, or other biological therapies within the last 30 days or during the study
12. Patients who received oral or parenteral corticosteroids, immunosuppressants, or cytotoxic agents within 30 days preceding the first study drug administration, or plan to use these medications during the study period
13. Patients who are pregnant or breastfeeding
14. Mental condition rendering the patient (or the patient’s legally acceptable representative[s]) unable to understand the nature, scope and possible consequences of the study
15. Patients who are incarcerated, including prisoners or patients compulsorily detained for treatment of either a psychiatric or physical (e.g., infectious disease) illness
16. Therapy with another investigational agent within thirty days of screening, or during the study
17. Patients who are considered by the investigator to have a significant disease, which can impact the study; patients who are cons
