  Purpose

Trafermin is a recombinant human basic fibroblast growth factor (bFGF; original development code, KCB-1), which is manufactured by genetic engineering using Escherichia coli by Kaken Pharmaceutical Co., Ltd. (Tokyo, Japan). Trafermin 0.01% cutaneous spray product kit consisting of a glass bottle containing lyophilized trafermin, a glass bottle with solvent for solution and a spray part to fit the glass bottle after reconstitution of the final product.

The investigators conduct a multinational, randomized, double-blind, placebo controlled, parallel-group, multicentre study consisting of a placebo run-in phase (2w), a treatment phase (max. 12w) and a follow-up phase (3mo+6mo). The primary objective of the study is to demonstrate a superior wound closure rate of diabetic foot ulcers (DFUs) of neuropathic origin after 12 weeks topical daily application of trafermin 0.01% spray compared with placebo, in addition to best local care (off-loading, dressings). Approximately 210 patients will be randomized and it is planned that this study will be conducted at approximately 30 investigational sites in an estimated 4 countries in Europe (Czech Republic,France,Hungary,Italy,).

Primary Outcome Measures:
  • Wound Closure Rate of Diabetic Foot Ulcers (DFUs) of Neuropathic Topical Daily Application of Trafermin 0.01% Spray Compared With Placebo, in Addition [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Wound closure is defined as 100% reepithelialization of the target DFU, without exudate.


Secondary Outcome Measures:
  • Relative Wound Area Regression of 40% or More at 6 Week [ Time Frame: 6 weeks ] [ Designated as safety issue: No ]
    The incidence of wound area regression of at least 40% at week 6 was considered as an important exploratory secondary efficacy variable. The wound area regression was calculated as percentage change from inclusion at week 6 using centralized wound area data.

Study Completion Date: February 2013
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Trafermin 0.01% spray Drug: Trafermin 0.01% spray
For ulcers with a maximum diameter (longest axis) of less or equal to 6 cm, the daily dose of trafermin 0.01% spray is 5 puffs (30 microgram) sprayed onto the wound surface. If the maximum diameter (longest axis) of the ulcer is >6 cm, the ulcer should be sprayed in two parts, i.e. 5 puffs (30 microgram) sprayed onto each half of the wound surface
Placebo Comparator: Matching placebo spray Drug: Trafermin 0.01% spray
For ulcers with a maximum diameter (longest axis) of less or equal to 6 cm, the daily dose of trafermin 0.01% spray is 5 puffs (30 microgram) sprayed onto the wound surface. If the maximum diameter (longest axis) of the ulcer is >6 cm, the ulcer should be sprayed in two parts, i.e. 5 puffs (30 microgram) sprayed onto each half of the wound surface
