This is an interventional treatment trial for Wounds focused on measuring ulcers, wounds, diabetes, venous ulcers, arterial ulcers, granulation tissue, protein kinase c Read More

Inclusion Criteria:

1. Subject is 18 years old and above
2. Have single/multiple wounds
3. Have a chronic hard to heal wound of various etiologies for at least 3 months of duration
4. Patient was treated for 14 days with SoC (screening run-in) and did not respond to treatment. "Response" is defined as formation of more than 10% of viable granulation tissue.
5. Wound area is larger than 5cm2 and smaller than 100 cm2.
6. Subject should be available for the entire study period, and be able and willing to adhere to protocol requirements
7. Subject must sign an informed consent form prior to undergoing any study- related procedures.
8. For female subjects only, the subject is either:

A. Surgically sterile B. At least 1 year post-menopausal.

C. Subject has consented to using one of the following acceptable methods of birth control for the times specified below:

• Intra-uterine device (IUD) in place for at least 3 months prior to screening visit and through study completion.
• Barrier method (condom or diaphragm) for at least 14 days prior to screening through study completion.
• Spermicide for at least 14 days prior to screening through study completion.
• Stable hormonal contraceptive for at least 3 months prior to screening visit through study completion.
• Surgical Sterilization (vasectomy) of partner at least 6 months prior to screening visit through study completion.

Exclusion Criteria:

1. Have a documented medical history of a significant hematological, cardiac, pulmonary, gastrointestinal, endocrine (other than Diabetes Mellitus type 1 or 2), or hepatic disease which per the physician's discretion prohibit them from entering the study.
2. Had any clinically significant illness per the physician's discretion during the last 4 weeks prior to the screening period.
3. Have a documented medical history . of HBV, HCV, HIV.
4. Severely immunosuppressed for any reason that would limit or preclude healing in the opinion of the Investigator.
5. Patient is currently receiving, or has received at any time within one month prior to enrollment, any medications or treatments known to affect the wound healing processes including Glucocorticosteroid treatment (Prednisone > 10mg/day or its equivalent), immuno-suppressive drugs, radiation therapy and chemotherapy.
6. Use of growth factors, allogeneic skin grafts/ skin graft products within one month prior to enrollment.
7. Females who are pregnant, lactating, of child-bearing potential, or post-menopausal for less than 1 year and not using a medically approved method of contraception (i.e., oral, transdermal, or implanted contraceptives, intrauterine device, diaphragm, condom, abstinence, or surgical sterility), or females who test positive on a blood-based pregnancy test.
8. Clinically significant blood and urinalysis tests per the physician's discretion.
9. Have any acute signs of infection in the wound, which could be linked to raised body temperature, abscess, necrosis, cellulitis or acute osteomyelitis.
10. Have sinus tracts or tunnels, purulent discharge , gangrene or severe drainage that will cause skin maceration per the physician's discretion.
11. Had any antibiotic treatment for acute infection during the screening period (prophylactic antibiotic treatment is allowed)
12. Intolerance to compression therapy if required for venous ulcers or inability to follow SoC according to the physician's instructions.
13. Had revascularization surgery during the past 3 months or be a candidate for revascularization surgery during the course of the study.
14. Active wound care therapies within the past 3 months (e.g., manufactured dermis, full-thickness skin, Becaplermin, split thickness autologous skin grafts at the site of the target wound)
15. Patients with poor nutritional status (albumin < 2.5g/dl), poor diabetic control (HbA1c > 12%), anemia (hemoglobin<8 g/dL), a leukocyte counts < 4,000// μl or >15000/μl, renal failure (Cr > 3 mg/dl);
16. Active deep venous thrombosis (DVT)
17. Patients with uncontrollable edema >+2
18. Patients who in the opinion of the investigator, for any reason other than those listed above will not be able to complete the study per protocol.
19. Participation in another clinical trial within 30 days prior to the Screening period or during this study.

20. History of mental illness that would preclude completion of the study
