Composition of Matter Patent Provides Coverage Until 2031

PR Newswire

SYDNEY and BEDMINSTER, N.J., June 12, 2013

SYDNEY and BEDMINSTER, N.J., June 12, 2013 /PRNewswire/ -- QRxPharma
Limited (ASX: QRX and OTCQX: QRXPY) announced today that the United States
Patent and Trademark Office (USPTO) issued the Company U.S. Patent #8,461,171
("'171 patent") titled "Hybrid Opioid Compounds and Compositions," which
expires in 2031.  This patent covers a hybrid morphine-oxycodone molecule
where these two different opioids are chemically linked. The '171 patent
covers the development of new chemical entities that have the potential to
provide better pain relief and fewer side effects than their individual
components.  The Company has related patents pending both internationally and
in the United States.

"This patent expands our intellectual property (IP) position and protects next
generation Dual-Opioid^® combination products that are chemically unique,"
said Dr. John Holaday, Managing Director and Chief Executive Officer. 
"Further, issuance of this patent enhances our long-term market exclusivity
for QRxPharma's Dual-Opioid^® products for the treatment of acute and chronic
pain."

Immediate release MOXDUO^® is a combination of two separate opioid salts
in the same capsule, and is presently under review at the US Food and Drug
Administration for the treatment of moderate to severe acute pain.  By
contrast, this newly issued patent covers different opioid combinations that
when linked together offer a new composition of matter having activity that is
greater than equimolar amounts of the molecules administered separately.
