This study is being done to find out if an investigational product called HP802-247 can help people with venous leg ulcers. Investigational means that HP802-247 has not been approved by the U.S. Food and Drug Administration (FDA).

This research is being done to compare the efficacy of HP802-247 plus compression therapy against Vehicle plus compression therapy in achieving complete wound closure over the 12-week treatment period. Vehicle looks the same as HP802-247 but contains no cells.

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Provide informed consent.
  • Age ≥ 18 years and of either sex.
  • Willing to comply with protocol instructions, including allowing all study assessments.
  • Have a venous leg ulcer (VLU) between the knee and ankle (at or above the malleolus), with a surface area ≥ 2.0 cm2 and ≤ 12.0 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.
