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.
