Title: A Phase II Randomized, Double Blind, Placebo Controlled Dose Finding Study Investigating the Efficacy of HP802-247 in Venous Leg Ulcers
Brief Summary: This is a 16-week study for subjects with a venous leg ulcer between the knee and ankle. This research is being done to determine the effectiveness of two dosing frequencies and two different concentrations of HP802-247, together with standard care, compared to placebo, plus standard care.


Options:
A: Inclusion Criteria:

* Provide informed consent.
* Willing to comply with protocol instructions, including allowing all study assessments.
* Have a venous leg ulcer (venous etiology)between the knee and ankle, at or above the malleolus.
* Venous insufficiency confirmed by duplex Doppler ultrasound examination for valvular or venous incompetence.
* Target ulcer duration greater than or equal to 6 weeks but less than or equal to 24 months.

Exclusion Criteria:

* Women who are pregnant or lactating
* Therapy with another investigational agent within thirty (30) days of Screening, or during the study.
* A target ulcer of non-venous etiologies.
* Refusal of or inability to tolerate compression therapy.
* Therapy of the target ulcer with tissue-engineered cell-based skin equivalents within 30 days preceding the Screening Visit.
* Therapy of the target ulcer with topical growth factors within 1 week preceding the Screening Visit.
B: Inclusion Criteria:

* Clinical indications of venous leg ulceration
* Ankle Brachial Index ≥ 0.7

* Other threat to safe participation.
C: Inclusion Criteria:

* Provide informed consent.
* Age ≥ 18 years and of either sex.

* Have a venous leg ulcer (VLU) between the knee and ankle (at or above the malleolus), with a surface area \>12 cm2 to ≤ 36 cm2
* Venous insufficiency confirmed by duplex Doppler ultrasound examination for valvular or venous incompetence.
* Arterial supply adequacy confirmed
* Target ulcer involves a full thickness skin loss, but WITHOUT exposure of tendon, muscle, or bone.
* Target ulcer duration ≥ 6 weeks but ≤ 104 weeks (24 months).
* Acceptable state of health and nutrition

Exclusion Criteria:

* History of anaphylaxis, serum sickness, or erythema multiforme reaction to aprotinin, bovine serum albumin or bovine serum proteins, penicillin, streptomycin, amphotericin B.
* Prior diagnosis of Systemic Lupus Erythematosus with elevated anti-DNA antibody titers, Buerger's disease (thromboangiitis obliterans), current diagnosis of vasculitis, or current diagnosis of claudication.
* Therapy with another investigational agent within thirty (30) days of Screening, or during the study.
* A target ulcer of non-venous etiologies (e.g., sickle cell anemia, necrobiosis lipoidica diabeticorum, pyoderma gangrenosum, vasculopathic or vasculitic).
* Documented history of osteomyelitis at the target wound location within 6 months preceding the Screening Visit.
* Refusal of or inability to tolerate compression therapy.
* Therapy of the target ulcer with autologous skin graft, Apligraf™, or Dermagraft™ within 30 days preceding the Screening Visit.
* History of cancer in the preceding 5 years (other than carcinoma in situ of the cervix or adequately treated non-melanoma skin cancers).
* Any prior exposure to HP802-247 or its vehicle.
D: Inclusion Criteria:

* Provide informed consent.
* Age ≥ 18 years and of either sex.
