Oxygen Biotherapeutics Issued U.S. Patent for Dermatologic Indications
Marks Company's 9th Patent Issued
MORRISVILLE, N.C. -- September 10, 2013
Oxygen Biotherapeutics, Inc., (“OBI”) (NASDAQ: OXBT) a developer of
oxygen-carrying therapeutics, today announced that the United States Patent
and Trademark Office has issued the Company patent#8,513,309, titled,
“Perfluorocarbons for use in Treating Pruritus.” This patent addresses methods
for treating pruritus (itching), a sensation that a patient instinctually
attempts to relieve by rubbing or scratching.
The newly issued patent addresses part of the global dermatological drugs
market, which is projected to reach $24.4 billion by 2015, according to market
research firm Visiongain. The Company is currently evaluating
commercialization strategies, which may include out-licensing, for
prescription dermatologic indications of PFC-based products for conditions
including allergic contact dermatitis, psoriasis and acne.
Among several beneficial properties, the Company’s platform technology of
proprietary perfluorocarbons (PFCs) carry 4 times more oxygen than red blood
cells (RBCs), have 20 times higher oxygen solubility than water, and form
stable emulsions 35 - 40 times smaller than RBCs.
In May of 2012, Oxygen Biotherapeutics completed a clinical study in which its
proprietary PFC-based emulsion showed efficacy in relieving histamine-induced
pruritus. Efficacy in treating pruritus was assessed, as reported by each
subject using a Visual Analogue Scale, a validated instrument used to evaluate
itch in clinical studies. The randomized, double-blind, placebo-controlled
study which included 30 healthy male and female volunteers aged 18-65 showed
that there was a profound drop in itch sensation when the Company’s PFC-based
topical treatment was applied.
"This latest patent builds upon our family of patents that address
dermatologic conditions. While our focus is the development of PFCs for
critical indications, we seek to unlock the value of our IP through
out-licensing non-core indications including those in dermatology," stated
Michael Jebsen, Interim CEO, President and Chief Financial Officer.
Oxygen Biotherapeutics now owns or in-licenses 9 issued patents for medical
and dermatological conditions with an average remaining life of approximately
18 years. Oxygen Biotherapeutics relies on a combination of use, method,
therapeutic, delivery and composition patents, patent applications, trade
secrets, and proprietary know-how in order to protect its medical products.
The Company is also expanding its IP portfolio by exploring new high-potential
therapeutic applications through third-party research collaborations.
