Clinical Trial Summary

To assess the efficacy of the PRP Concepts Fibrin Bio-Matrix and compare its performance with usual and customary practice for the treatment of chronic non-healing venous leg ulcers (VLU).

Description:

This is a prospective, randomized, single-blind, controlled, multi-center study for subjects undergoing VLU treatment. Qualified subjects will be randomized (1:1); test group (PRP Concepts Fibrin Bio-Matrix) and control group (usual and customary practice). The study will consist of 3 periods: a screening period, an active treatment period, and a follow-up period (if healed). Approximately 250 subjects will be enrolled. Subjects will be ≥18 years of age with a VLU (greater than 4 weeks duration). Each subject will be enrolled in the active treatment period for up to 12 weeks, or to closure of wound with a confirmatory visit 2 weeks after wound closure, whether such closure occurs at 12 weeks or earlier.
