Nuvo Research provides a PENNSAID(R) franchise update

July 23, 2012

MISSISSAUGA, ON, July 23, 2012 /PRNewswire/ – Nuvo Research Inc. (TSX: NRI), a
specialty pharmaceutical company dedicated to building a portfolio of
products for the topical treatment of pain, today is providing an
update on the status of its PENNSAID franchise.

PENNSAID (diclofenac sodium topical solution) 1.5% w/w U.S. Patent

The United States Patent Office has issued Patent # 8,217,078 relating
to a method of using PENNSAID (PENNSAID Patent).  The PENNSAID Patent
expiry date is July 10, 2029.

Nuvo’s U.S. licensing partner, Mallinckrodt Inc. (Mallinckrodt), the
Pharmaceuticals business of Covidien plc, has listed the PENNSAID
Patent in the U.S. Food and Drug Administration’s (FDA) Orange Book. 
The Orange Book listing requires any Abbreviated New Drug Application
(ANDA) applicant seeking FDA approval for a generic version of PENNSAID
prior to expiration of the patent to notify Nuvo and Mallinckrodt of
its ANDA before it can obtain FDA approval.  Prior to the Orange Book
listing, there was no such requirement on the generic applicants.

Subsequent to the Orange Book listing, Nuvo and Mallinckrodt received
Paragraph IV certification notices from three companies advising Nuvo
and Mallinckrodt that they have filed an ANDA with the FDA seeking
approval to market a generic version of PENNSAID.  Nuvo and
Mallinckrodt are evaluating the notice letters and have the right to
commence legal action against each of the ANDA applicants to enforce
its patent rights.

Nuvo is currently prosecuting additional patent applications in the
United States that would cover methods of using PENNSAID.  In addition,
Nuvo is prosecuting patent applications throughout the world that
provides protection for PENNSAID 2%.

PENNSAID 2% Regulatory Filing

Mallinckrodt has advised Nuvo that the FDA has accepted the New Drug
Application (NDA) for PENNSAID 2% for review.  Mallinckrodt had
submitted a supplemental New Drug Application (sNDA) for PENNSAID 2% to
the FDA which the FDA requested Mallinckrodt revise to an NDA. 
Mallinckrodt complied with the request and resubmitted the
application.  The FDA has set a Prescription Drug User Fee Act (PDUFA)
date of March 4, 2013 for action on the submission.

Under the terms of a U.S. Licensing and Development Agreement signed in
June 2009, Mallinckrodt assumed full responsibility for managing,
executing and paying for all development activities for PENNSAID 2%.

“We are extremely pleased that we have been able to secure patent
protection for the use of PENNSAID and have made progress with the
PENNSAID 2% regulatory filing,” said Dan Chicoine, Nuvo’s Chairman and
Co-CEO.  “The new patent provides us with IP protection for PENNSAID
and an approaching PDUFA date in early 2013 allows us to move forward
with our strategy of obtaining FDA regulatory approval for PENNSAID
2%.”

IMPORTANT RISK INFORMATION ABOUT PENNSAID(® )

     _____________________________________________________________________
    |Cardiovascular Risk                                                  |
    |                                                                     |
    |    --  Nonsteroidal anti-inflammatory drugs (NSAIDs) may cause an   |
    |        increased risk of serious cardiovascular thrombotic events,  |
    |        myocardial infarction, and stroke, which can be fatal. This  |
    |        risk may increase with duration of use. Patients with        |
    |        cardiovascular disease or risk factors for cardiovascular    |
    |        disease may be at greater risk.                              |
    |    --  PENNSAID is contraindicated in the perioperative setting of  |
    |        coronary artery bypass graft (CABG) surgery.                 |
    |Gastrointestinal Risk                                                |
    |                                                                     |
    |    --  NSAIDs cause an increased risk of serious gastrointestinal   |
    |        adverse events including bleeding, ulceration, and           |
    |        perforation of the stomach or intestines, which can be fatal.|
    |        These events can occur at any time during use and without    |
    |        warning symptoms. Elderly patients are at greater risk for   |
    |________serious_gastrointestinal_events._____________________________|

PENNSAID is also contraindicated in patients:

        --  with a known hypersensitivity to diclofenac sodium or any other
            component of PENNSAID
        --  who have experienced asthma, urticaria, or allergic-type
            reactions after taking aspirin or other NSAIDs. Severe, rarely
            fatal anaphylactic-like reactions to NSAIDs have been reported
            in such patients.

Elevation of one or more liver tests may occur during therapy with
NSAIDs. PENNSAID should be discontinued immediately if abnormal liver
tests persist or worsen.

Use with caution in patients with fluid retention or heart failure.
Hypertension can occur with NSAID treatment. Monitor blood pressure
closely with PENNSAID treatment.

Long-term administration of NSAIDs can result in renal papillary
necrosis and other renal injury. Use PENNSAID with caution in patients
at greatest risk of this reaction, including the elderly, those with
impaired renal function, heart failure, liver dysfunction, and those
taking diuretics and ACE-inhibitors.

Should not be used in pregnant or lactating women and is not approved
for use in pediatric patients.

Anaphylactoid reactions may occur in patients without prior exposure to
PENNSAID. NSAIDs can cause serious skin adverse events such as
exfoliative dermatitis, Stevens-Johnson Syndrome (SJS), and toxic
epidermal necrolysis (TEN), which can be fatal.

The most common treatment-related adverse events in patients receiving
PENNSAID were application site skin reactions including dry skin (32%),
contact dermatitis characterized by skin erythema and induration (9%),
contact dermatitis with vesicles (2%) and pruritus (4%). In a long term
safety study, contact dermatitis occurred in 13% and contact dermatitis
with vesicles in 10% of patients, generally within the first 6 months
of exposure, leading to a withdrawal rate for an application site event
of 14%.  Other common adverse events greater than placebo include:
dyspepsia (9%), abdominal pain (6%), flatulence (4%), diarrhea (4%) and
nausea (4%).

Do not apply to open wounds. Protect treated knee(s) from natural or
artificial sunlight. Topicals such as sunscreen and bug repellant may
be applied after PENNSAID treated knee(s) are completely dry. Avoid
contact of PENNSAID with eyes and mucous membranes. Wash and dry hands
after use.

Concurrent use with oral NSAIDs should be avoided unless benefit
outweighs risk and periodic laboratory evaluations are conducted.
