Nuvo Research® announces U.S. FDA approval of third-party generic of PENNSAID 1.5%

MISSISSAUGA, ON, May 29, 2014 - Nuvo Research Inc. (TSX:NRI.TO ), a specialty pharmaceutical company with a diverse portfolio of topical and immunology products today announced that a third party has received U.S. Food and Drug Administration (FDA) approval to market and sell a topical diclofenac sodium 1.5% solution in the United States.  The product is a generic version of Nuvo's PENNSAID (diclofenac sodium topical solution) 1.5% w/w (PENNSAID 1.5%).

Mallinckrodt Inc. (NYSE:MNK ) is Nuvo's U.S. commercial licensee for the sale of both PENNSAID 1.5% and its follow-on product PENNSAID (diclofenac sodium topical solution) 2% w/w (PENNSAID 2%).  PENNSAID 2% was approved by the FDA on January 16, 2014 and was launched by Mallinckrodt in February 2014.

 PENNSAID 2% is the first twice per day dosed topical non-steroidal anti-inflammatory drug (NSAID) available in the U.S. for the treatment of the pain of osteoarthritis of the knee.  It is protected by 5 U.S. patents that are listed in the FDA's Approved Drug Products with Therapeutic Equivalence Evaluations database or "Orange Book".

Mallinckrodt has advised Nuvo that its strategy is to convert PENNSAID 1.5% patients and prescribers to PENNSAID 2%.  Since the launch of PENNSAID 2%, U.S. prescriptions for PENNSAID 1.5% have declined and been offset by increased PENNSAID 2% prescriptions.  The most recent IMS data for the week ended May 16, 2014, indicated that the number of PENNSAID 2% prescriptions exceeded the number of PENNSAID 1.5% prescriptions.  Nuvo receives a 20% of net sales royalty on Mallinckrodt's U.S. sales of both PENNSAID 1.5% and PENNSAID 2%.

IMPORTANT RISK INFORMATION

CONTRAINDICATIONS

• 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

WARNINGS AND PRECAUTIONS

• 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.
• 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.
• Wash and dry hands before and after use.  Avoid contact of PENNSAID with the eyes and mucous membranes
• PENNSAID was not evaluated under the conditions of heat application, occlusive dressings overlay, or exercise; therefore, concurrent use of PENNSAID under these conditions is not recommended.
• Do not:
       apply PENNSAID to open wounds.
       shower for at least 30 minutes after applying PENNSAID.
       wear clothing over the PENNSAID treated knee until the treated knee is dry
• Protect treated knee(s) from natural or artificial sunlight. Topicals, such as sunscreen and bug repellent, may be applied after PENNSAID treated knee(s) are completely dry.
• Concurrent use with oral NSAIDs should be avoided unless benefit outweighs risk and periodic laboratory evaluations are conducted
