Observational Study Providing 12 Months of Safety Follow-Up From First Exposure to HP802-247

Study Overview
=================
Brief Summary
-----------------
This observational safety follow-up study enrolled subjects from the 802-247-09-032 study with the investigational product HP802-247 for venous leg ulcers, who received at least one application of HP802-247 or Vehicle (Placebo). This study is being done for the following purposes: to identify new adverse events, to examine ongoing adverse events not resolved in subjects who participated in the 802-247-09-032 trial, to record wound status, and to determine if there are differences in Health Related Quality of Life (HRQoL) associated with the treatment assignment from the 802-247-09-032 Trial. About 440 subjects were to participate depending upon subject enrollment from the previous study, 802-247-09-032. The study was conducted in approximately 50 sites in Europe.

Detailed Description
-----------------
Subjects transitioned to this observational study immediately upon exit from the 802-247-09-032 trial. This ensured a total of 12 months of safety observations and wound status data were obtained from the time of the first application of HP802-247. This study provided consecutive visits at intervals of 8 weeks until a total of 12 months of safety follow-up had been achieved, based on the initial application of Investigational Medicinal Product in the prior study. Specifically, this study examines all new and unresolved ongoing adverse events.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assess new adverse events, and ongoing adverse events not resolved, in subjects who were exposed to a Investigational Medicinal Product in the 802-247-09-032 trial. | The evaluation of safety included analysis of new test article-related events, as well as continued follow-up of those adverse events that originated in the prior study. | Up to 12 months from first application of test article in the 802-247-09-032 study | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Follow-up on the status of the target ulcer as open, re-opened or closed. | At each study visit the status of the target ulcer was assessed as remaining closed, re-opened, or a new closure. | Up to 12 months from first application of test article in the 802-247-09-032 study |
