"We are very pleased that we have been able to secure additional patent protection for PENNSAID 2%," said Tina Loucaides, Nuvo's Vice President and General Counsel. "This patent, together with our recently announced method of use patent for PENNSAID and PENNSAID 2% gives us a strong patent portfolio that will support the PENNSAID franchise."
About PENNSAID 2%
PENNSAID 2% is the follow-on product to original PENNSAID, a topical non-steroidal anti-inflammatory drug (NSAID). PENNSAID 2%, which is not approved by the FDA, contains 2% diclofenac sodium compared to 1.5% for original PENNSAID. It is more viscous than original PENNSAID, is supplied in a metered dose pump bottle and is designed to be applied twice each day compared to four times a day for original PENNSAID. If approved by the FDA, PENNSAID 2%, like PENNSAID, will be indicated for the treatment of the signs and symptoms of osteoarthritis (OA) of the knee.

IMPORTANT RISK INFORMATION
| Cardiovascular Risk
PENNSAID is 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.
