The TRAfermin in Neuropathic Diabetic Foot Ulcer Study - Northern Europe The TRANS-North Study (TRANS-North)
A Phase III, Double-Blind, Placebo Controlled, Parallel Group, International, Multicenter Study of 12 Weeks Treatment With Trafermin 0.01% Spray in Patients With Diabetic Foot Ulcer of Neuropathic Origin
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.

- Male or female patients age 18 years or older.
- Type 1 or 2 diabetes.
- A single full-thickness DFU that has been present for at least 2 weeks.
- DFU wound surface area below or equal 34 cm2 on the target foot.
- No exposure of bone in the target DFU.
- Neuropathy confirmed by loss of protective sensation to monofilament test (Semmes-Weinstein 5.07 monofilament).
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:
- All of the selection criteria and none of the exclusion criteria are met.
- Completed the 2-week placebo run-in period during which they were compliant to off-loading and to daily application of placebo spray, without major protocol violation. Compliance with the placebo run-in treatment regimen must be "excellent" or "acceptable".
- Glycosylated hemoglobin (HbA1c) below or equal 10% (from a blood sample taken during the placebo run-in period).
Non-infected target foot DFU of confirmed neuropathic origin with:
- 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 above 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

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: 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
|
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
