  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.

We 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 a maximum of 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 40 investigational sites in Europe.

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


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.

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

Criteria

Selection Criteria

Patients who fulfill all of the following criteria (and none of the exclusion criteria described below) are eligible to enter the placebo run-in phase of the study:

  1. Provide written informed consent to participate.
  2. Male or female patients age 18 years or older.
  3. Type 1 or 2 diabetes.
  4. A single full-thickness DFU that has been present for at least 2 weeks.
  5. DFU wound surface area below or equal 34 cm2 on the target foot.
  6. No exposure of bone in the target DFU.
  7. Neuropathy confirmed by loss of protective sensation to monofilament test (Semmes-Weinstein 5.07 monofilament).
  8. No predominant ischemia requiring further exploration or treatment, and confirmed by either:

    • ABPI on the target leg (>0.9; below or equal 1.3) or if ABPI is >1.3 or is not assessable,TBPI on target foot ³above or equal 0.7, OR
    • ABPI on target leg (above or equal 0.7 - below or equal 0.9) or if ABPI is >1.3 or is not assessable, TBPI on target foot <0.7, AND a toe blood pressure >40 mmHg

Inclusion Criteria

Patients who fulfill all of the following criteria are eligible for randomization:
