MoxDuo(TM) IR Demonstrates Fewer Side Effects than Percocet(R)

SYDNEY and BEDMINSTER, N.J., Aug. 26 /PRNewswire-AsiaNet/ –

Pain relieving effects of MoxDuo(TM) IR are dose-related with a better safety
profile than Percocet(R) in patients with post-operative pain following total
knee replacement

QRxPharma Limited (ASX: QRX and OTCQX: QRXPY) announced today successful
completion of its pilot study to evaluate the analgesic efficacy and safety
profile of MoxDuo(TM) IR (immediate release) capsules in patients with moderate
to severe pain following total knee replacement surgery. When compared at
equianalgesic doses with Percocet(R), the second most widely prescribed opioid
in the US, MoxDuo(TM) IR demonstrated greater overall tolerability with
substantially fewer incidences of moderate to severe nausea, vomiting,
constipation, and hypotension than Percocet(R). Scheduled for launch in 2011,
MoxDuo(TM) IR targets the acute pain market; a $2.5 billion segment of the $7
billion spent annually on prescription opioids in the US.

"This study serves to reinforce earlier clinical findings that showed
improved tolerability and again demonstrates the value of our Dual-Opioid(TM)
platform as MoxDuo(TM) IR opens the therapeutic window for treating patients
suffering from acute post-surgical pain," said Dr. John Holaday, Managing
Director and Chief Executive Officer, QRxPharma. "We believe the MoxDuo(TM)
product portfolio – including immediate release, controlled release and
intravenous formulations – will significantly improve patient care, providing
equal or better analgesia with fewer and/or less intense side effects than
current standards of care."

MoxDuo(TM) IR is the first patented analgesic product in the world that
consists of two opioid drugs (a fixed ratio of morphine and oxycodone). While
many analgesic combination drugs exist that contain opioids with mild pain
drugs such as aspirin, ibuprofen or acetaminophen, combination products such as
Percocet(R) – which contains an opioid (oxycodone) combined with acetaminophen
(like Tylenol(R)) – have been the subject of recent FDA scrutiny due to their
potential for causing significant adverse effects on liver and gastrointestinal
function.

To date, more than 400 patients in six clinical trials have received
MoxDuo(TM) IR for different forms of post-surgical pain (bunionectomy and total
knee replacement). Study results with MoxDuo(TM) IR consistently demonstrate
fewer side effects than observed with morphine alone, oxycodone alone and now
with Percocet(R).

In this open label trial, each group of patients who experienced moderate
to severe post-operative pain following total knee replacement surgery were
treated every four to six hours over a 48-hour period. The study enrolled a
total of 44 patients at five US clinical research sites.

All primary study objectives were met comparing: (1) the analgesic efficacy
and safety profile of MoxDuo(TM) IR against control groups of patients
receiving Percocet(R), a frequently used opioid for the treatment of pain; and
(2) a flexible dosing regimen of MoxDuo(TM) IR against a fixed low dose
(3/2mg). Patients receiving the flexible dosing regimen of MoxDuo(TM) IR
achieved significantly greater pain relief than those receiving the low dose
formulation (p<0.05).

Data collected from this study provide additional guidance for optimising
the design and implementation of pending pivotal Phase 3 studies as the Company
prepares for New Drug Application (NDA) filings with the US Food and Drug
Administration (FDA) in 2010.

MoxDuo(TM) IR, the Company’s lead product candidate, is part of a larger
Dual-Opioid(TM) portfolio including intravenous (MoxDuo(TM) IV) and controlled
release (MoxDuo(TM) CR) formulations. These formulations are designed to
incorporate tamper resistance and reduced abuse liability as appropriate.

Dr. Bruce Nicholson, a leading pain physician in the US, commented on these
results: "The concept of combining morphine and oxycodone makes sense based on
the clinical data generated to date, and has benefited my patients in managing
their acute and chronic pain needs. Results of this study reinforce that the
clinical advantages of MoxDuo(TM) IR have the potential to change the
traditional methods of treating moderate to severe pain by providing better
pain relief without many of the debilitating side effects seen with traditional
opioid drugs."

Based on the Company’s July 2008 FDA meeting, final Phase 3 studies for
MoxDuo(TM) IR will include: (1) a "double-blind combination rule" trial in
patients experiencing post-surgical (bunionectomy) pain that compares
MoxDuo(TM) IR against morphine alone and oxycodone alone and (2) a double-blind
controlled study to evaluate the effectiveness of MoxDuo(TM) IR in patients
following total knee replacement. No additional pharmacology, toxicology or
long-term clinical safety studies will be required for regulatory submission
and market approval.
