Nuvo Research Provides PENNSAID Commercial Update
November 14, 2011
- FDA requests U.S. licensee cease distribution of PENNSAID sample bottles due to concerns of incorrect administration by patients
- No disruption to commercial availability
MISSISSAUGA, ON, Nov. 14, 2011 /CNW/ -Nuvo Research Inc. (TSX: NRI), a specialty pharmaceutical company dedicated to building a portfolio of products for the topical treatment of pain and the development of its immune modulating drug candidate WF10, today announced that its U.S. marketing partner, Mallinckrodt Inc., a Covidien company, has advised Nuvo that, at the request of the U.S. Food and Drug Administration (FDA), Mallinckrodt has ceased distribution of 15 mL sample bottles of Pennsaid to U.S. healthcare professionals. Mallinckrodt is the subsidiary of Covidien that holds the U.S. marketing rights to PENNSAID and that deals with the FDA in all matters respecting PENNSAID. Mallinckrodt has advised Nuvo that it had previously submitted to the FDA five reports of patients who had used an incorrect route of drug administration with PENNSAID topical solution either orally (into the mouth) or optically (into the eye) using the 15 mL sample bottle. PENNSAID is a topical solution approved only for direct application to the skin overlying the knee for the treatment of the signs and symptoms of osteoarthritis (OA) of the knee. There were no serious adverse outcomes in these five patients, and in all reported confirmed cases, the adverse events that resulted from the improper route of administration were resolved.
Mallinckrodt has advised Nuvo that the FDA request does not extend to the 150 mL commercial size bottles of PENNSAID marketed by Mallinckrodt. Nuvo does not expect any disruption in PENNSAID's commercial supply and Mallinckrodt remains free to market and distribute the product actively in the United States. Mallinckrodt has advised Nuvo that it intends to communicate further with the FDA in an effort to resolve this matter in a timely fashion. Nuvo currently receives manufacturing revenues from Mallinckrodt for production of the sample bottles and expects that manufacturing of the sample bottles will be suspended for an indeterminate period of time. Nuvo believes that if Mallinckrodt is unable to resolve this matter in a timely fashion, its inability to provide samples to U.S. healthcare professionals could have a negative impact on PENNSAID sales in the U.S. and the royalties Nuvo receives on these sales, unless Mallinckrodt successfully implements mitigating strategies.
PENNSAID (diclofenac sodium topical solution, 1.5% w/w) is an FDA approved nonsteroidal anti-inflammatory drug (NSAID) indicated for the treatment of the signs and symptoms of OA of the knee(s). PENNSAID is currently recommended for topical application of 40 drops 4 times per day to the front, back and sides of the knee. Additional information for U.S. patients and physicians is available at www.pennsaid.com.

IMPORTANT RISK INFORMATION ABOUT PENNSAID
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.
