Title: A Phase 3 Randomized, Double Blind, Vehicle Controlled Study Investigating the Safety and Efficacy of HP802-247 in the Treatment of Venous Leg Ulcers >12 cm2 to ≤ 36 cm2
Brief Summary: 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).

At least 250 subjects will participate. The study is going to be conducted in approximately 50 sites in the United States and Canada.

* 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.
