Easyef® Ointment
Recombinant Human Epidermal Growth Factor
Easyef® Ointment
General Information
What is EGF?
Epidermal Growth Factor (EGF) is a single-chain polypeptide consisting of 53
amino acids with a molecular weight of about 6,200 Daltons. Six cysteine
residues in the sequence of hEGF from three disulfide bonds are required for
hEGF to be biologically active.
EGF was first isolated from the submaxillary glands of adult male mice. Human
EGF was discovered in human urine as an inhibitor of gastric acid secretion.
Today, hEGF has become one of the most attractive growth factors in life
sciences as well as biotechnological fields.
Human EGF is a potent stimulator of epithelial and endothelial cells and
fibroblast proliferation both in vitro and in vivo, which results in its potential as a
promising healing agent for the treatment of various skin and corneal wounds. In
dermatology, EGF can be used as a healing agent for skin wounds, such as
diabetic ulcers, bed sores, venous stasis ulcers, skin burns and surgical incisions.
In ophthalmology, EGF can be utilized as a healing agent for corneal ulcers and
ophthalmic surgery, such as corneal transplantation and excimer laser
keratectomy, and the prevention of corneal degeneration. It is also a good
candidate for the treatment of gastric ulcers because it inhibits gastric acid
secretion and regenerates gastric mucosal layer.

Mechanism of EGF Action
1. Re-epithelialization
EGF promotes epithelial cells to proliferate and move to fill wounds.
2. Promotion of granulation tissue
EGF stimulates fibroblasts in dermal tissue to facilitate dermal cells to
differentiate and proliferate.
3. Angiogenesis
EGF promotes endothelial cells to proliferate to regenerate blood vessels.

2. Clinical study
► Indication: Wound healing (Skin graft donor site model)
► Methodology: Placebo-controlled, randomized, double-blind, multi-center study
► Primary endpoint: Healing time by the direct evaluation(naked eye) of skin graft donor site
► Result: The test group displayed statistically significant 1.0 day faster healing time
compared to the control group (p=0.0005).

Key Benefits and Features
Wound healing ointment with a new concept, containing EGF, a
granulation ingredient (granulation tissue) in the human body, offered
first in Korea.
Safe because it contains no steroids or antibiotics.
White blood cells or macrophages themselves, which are created during the
healing process in our body, suppress bacteria, to some extent. Therefore,
this medicine does not contain a steroid or an antibiotic of which the
excessive use may make us tolerant of the antibiotic.
Proven in its safety and healing effect through a clinical studies in
Korea.
Top medical staffs from three prestigious Korean Institutions (Asan Medical
Center, Severance Hospital, and Samsung Medical Center) joined the
clinical procedures, and approved the safety and remarkable healing effect
of EGF.
