A Study Evaluating Topical Recombinant Human Vascular Endothelial Growth Factor (Telbermin) for Induction of Healing of Chronic, Diabetic Foot Ulcers

An Exploratory, Double-Blind, Randomized, Placebo Controlled Study Evaluating Topical Recombinant Human Vascular Endothelial Growth Factor (Telbermin) for Induction of Healing of Chronic, Diabetic Foot Ulcers

This is a Phase I, double blind, randomized, placebo-controlled study that will enroll approximately 50 adult subjects with Type 1 or Type 2 diabetes mellitus and chronic, diabetic foot ulcers. The study will be conducted at approximately 12 investigational sites in the United States.

• Known prior inability to complete required study visits during treatment period
• Use of any other investigational drug or therapy on the study foot within the past month
• Previous use of a platelet-derived or other growth factors on the study ulcer within the past 3 months
