10. Willing and able to comply with study procedures, including study visits and study dressing regimens (or have family member/friend willing and able), including ability of the subject to tolerate limb compression bandage
11. Subject has read and signed the IRB-approved Informed Consent Form before screening procedures are undertakenExclusion Criteria:

Exclusion

1. Study ulcer deemed by the Investigator to be caused by a medical condition other than venous insufficiency.

6. Study ulcer is less than 4.0 cm2 or greater than 100.0 cm2 (Determined by MolecuLight Imaging Device).
7. Study ulcer extends more than 50% below the malleolus.
8. Study ulcer has been treated with tissue engineered material (e.g., Apligraf® or Dermagraft®) or other scaffold materials (e.g., Oasis, PuraPly AM or Matristem) within the last 30 days.
9. Study ulcer requiring negative pressure wound therapy or hyperbaric oxygen during the course of the trial.
10. Study ulcer decreases in area by 30% or more during the 14 days screening period.
11. Subjects who are unable to understand the aims and objectives of the trial or have a known history of poor adherence with medical treatment.
12. Presence of any condition(s) that seriously compromises the subject's ability to complete this study.
13. Subjects with a BMI>65
14. Subject is an active smoker
15. Subject has any history of fish allergy or a known sensitivity to any of the SoC materials which come into contact with the skin
16. Ankle-Branchial Index (ABI) less than 0.80 or greater than 1.3
17. Presence of any monophasic waveforms on segmental Arterial Doppler/Pulse Volume Recording
18. Subject is on Dialysis
19. Any active cancer other than a nonmelanoma skin cancer; any previous cancer must be in remission for at least 1 year: bone cancer of metastatic disease of the affected limb, or has had chemotherapy within the last 12 months
20. Suspicion of malignancy within VLU. Any wound that has been present for > 6 months and hasn't previously been biopsied, a biopsy must be performed. Also, if a clinical suspicion of malignancy exists in the opinion of the Investigator, a biopsy should be performed regardless of duration of wound.
21. Life expectancy < 6 months
22. Subject has received within 28 days of screening a treatment which is known to interfere with or affect the rate and quality of wound healing (e.g., thrombolysis, systemic steroids, immunosuppressive therapy, autoimmune disease therapy, dialysis, radiation therapy,chemotherapy, revascularization surgery) to the leg or who may receive such medications during the screening period or who has anticipated to require such medications during the course of the study.
23. History of immunodeficiency or any illness or condition that could interfere with wound healing e.g., lymphedema, end-stage renal disease, severe malnutrition, liver disease, aplastic anemia. Raynaud's Syndrome, connective tissue disorder, acquired immune deficiency syndrome, HIV positive, or sickle cell anemia
24. Untreated osteomyelitis
25. Hepatitis
26. Acute deep venous thrombosis
27. Allergy to lidocaine and/or epinephrine
28. Subject's inability to successfully tolerate compression therapy that is changed weekly
29. All females of childbearing potential who are not using a highly effective method of birth control (failure rate less than 1% per year), such as implants, injectables, combined oral contraceptives, some IUDs, practice sexual abstinence or have a vasectomized partner.
30. The following are prohibited within 30 days prior to randomized treatment and throughout the study

1. Heat lamps 2. UV lights 3. Whirlpool baths 4. Hyperbaric oxygen 5. Jet water streams (other than gentle saline irrigation)

*Note: an ulcer that is deemed infected at S1 or TV1 might be eligible for re-screening once the infection is resolved, at the investigator's discretion.
