ABSTRACT
OBJECTIVE: To evaluate the efficacy, tolerability, and safety of a
novel wound dressing containing epidermal growth factor (EGF)
in a collagen-gel matrix on hard-to-heal venous leg ulcers.
PATIENTS AND METHODS: The authors included 33 hard-to-heal
venous leg ulcers found on 31 patients. The EGF-containing
dressing was applied 3 times while best practice conservative wound
treatment was continued. Patients were followed up with after
1, 2, and 3 months to evaluate (a) the wound size, (b) the ease of
application and dissolution of the dressing, and (c) the wound
dressing by means of a scale ranging from 1 to 5 (1 = best, 5 = worst).
RESULTS: The protocol was completed by 25 of 31 patients. The
reasons for discontinuation were wound infection, pain, and lost to
follow-up (n = 2 each, respectively). After 3 months, the average wound
surface was significantly reduced (from 33.69 cm
2
to 18.94 cm
2
,
P = .023). On a scale from 0 to 100, the wound dressing was
evaluated as very easy to apply and highly dissolvable (mean value of
97.14 and 98.11, respectively; 100 = very easy to apply or 100%
dissolution). The dressing was generally well tolerated and scored a
mean overall rating of 2.16 by healthcare specialists and 2.40 by patients.
CONCLUSION: The authors’ results demonstrate that the novel
EGF-containing wound dressing was generally well tolerated and
safe. Combined with the significant wound surface reduction, it
can be regarded as an adequate novel treatment option for patients
with hard-to-heal venous leg ulcers.

INTRODUCTION
Considering that hard-to-heal chronic leg ulcers cause consider-
able healthcare expenses, there is an urgent need for efficient and
evidence-based treatment options.
1
In venous leg ulcers, improved
healing and lower recurrence rates could be demonstrated for su-
perficial venous surgery, endovenous laser therapy, and compres-
sion therapy.
2Y7
In addition, certain debridement techniques show
improved healing outcomes.
8
Patients with hard-to-heal leg ulcers commonly have medical
conditions that limit the therapeutic options for conservative strate-
gies. However, in contrast to the benefit of compression therapy,
multiple randomized controlled trials comparing different wound
dressings could not prove a significant impact on the healing of
venous leg ulcers.
9
With regard to epidermal growth factor (EGF) treatment for ve-
nous leg ulcers, previous studies showed divergent effects. For
topical EGF, a greater reduction of the wound size and more healed
ulcers were reported compared with the placebo.
10
Studies investi-
gating topical transforming growth factor A2 and repifermin (recom-
binant human keratinocyte growth factor 2) concluded a potential
positive effect on the closure of venous leg ulcers.
11,12
A current
systematic Cochrane review found no evidence for improved heal-
ing of chronic wounds with autologous platelet-rich plasma, which
contains high concentrations of growth factors.
13
The objective of the authors’ prospective, noncomparative
study was to investigate the effect of a novel wound dressing
containing EGF in a collagen-gel matrix (Neoderm; Ars Arthro,
Ankara, Turkey) for the treatment of hard-to-heal chronic venous
leg ulcers.
METHODS
The study protocol conformed to the ethical guidelines of the 1975
Declaration of Helsinki and was approved by the responsible
ethics committee (vote no. 11-265). This study included 31 pa-
tients with 33 hard-to-heal chronic venous leg ulcers enrolled from
3 specialized German wound centers. All patients with ulcers not
