Nuvo Research Inc. Announces Scientific Presentation at the Annual Meeting of the American Medical Society for Sports Medicine

Data Evaluating Synera^® for the Treatment of Shoulder Impingement Syndrome

MISSISSAUGA, ON, April 19, 2013 /PRNewswire/ - Nuvo Research Inc. (TSX: NRI), a specialty pharmaceutical company dedicated to building a portfolio of products for the topical treatment of pain today announced that researchers presented scientific data related to Synera^® (70 mg lidocaine/ 70 mg tetracaine) topical patch at the 22^nd Annual Meeting of the American Medical Society for Sports Medicine (AMSSM) in San Diego, California. The data was a pooled analysis of two open label pilot studies of Synera in shoulder impingement syndrome (SIS) and showed that Synera provided clinically significant improvement of pain and function in SIS.

Synera is a topical patch that is approved in the United States and Europe for use on intact skin to provide local dermal analgesia for superficial venous access and superficial dermatological procedures such as excision, electrodessication and shave biopsy of skin lesions. Synera is not yet approved for the treatment of SIS and was used in the reported studies on an investigational basis.

"The data being presented at AMSSM demonstrates Nuvo's commitment to exploring the potential utility of the Synera Patch for new indications, and we are excited about the outcome from the pooled analysis of these two initial pilot studies," said Arnold Gammaitoni, Pharm.D., Vice President, Scientific Affairs at Nuvo.

"In these studies, treatment with Synera resulted in meaningful improvements in both range of motion and pain scores," said Richard Radnovich, D.O., principle investigator, Injury Care Medical Center, Boise, Idaho. "The patch topically delivers two medications into the local tissues with the assistance of heat and effectively delivers drugs to the musculoskeletal region causing the pain and dysfunction, while minimizing systemic exposure."

About the Studies

The data was pooled from two open-label, 14-day, pilot studies of Synera in patients with SIS. Both studies were conducted at the Injury Care Medical Center, Boise, Idaho. The studies included male and female patients at least 18 years of age with moderate to severe pain associated with SIS. Subjects applied a single Synera patch to the painful shoulder for 2-4 hours twice daily at approximately 12-hour intervals.

A total of 49 patients (25 female, 24 male) were included in the analysis. 84% of patients completed the studies. 70% of patients experienced a clinically meaningful reduction (30% reduction) in average pain scores. In addition, improvements were noted by reductions in pain interference with sleep, work, and general activity, as well as, improvements in range of motion in the affected shoulder. Approximately 76% of patients reported being "satisfied" or "very satisfied" with the treatment.

No serious adverse events were reported in either study. Application site erythema was the most common adverse event observed in 32 patients (65%). All cases of erythema were mild or moderate in severity and no patients withdrew from the studies due to erythema. Other application site reactions included skin irritation (n=2), pruritus (n=2), dermatitis (n=1), induration, (n=1), rash (n=1), swelling (n=1), urticaria (n=1), and bullous reaction (n=1). All were mild in severity, except the episode of dermatitis which was considered moderate in severity.

About SIS

Shoulder impingement syndrome (SIS) is a common cause of shoulder pain and dysfunction and is typically caused by an impingement of the rotator cuff tendon. Persistent shoulder pain is a common reason for consulting with a primary care physician. Shoulder pain in adults aged <70 years is estimated to be between 7% and 27%. The goals of treatment are to reduce pain and improve function so patients may fully participate in physical rehabilitation. In addition to physical therapy, the two most common medications used to treatment pain in SIS are non-steroidal anti-inflammatory agents (NSAIDs) and corticosteroid injections.

About Synera

Synera (lidocaine 70 mg/tetracaine 70 mg) topical patch is a combination amide and ester local anesthetic topical patch indicated for use on intact skin to provide local dermal analgesia for superficial venous access and superficial dermatological procedures such as excision, electrodessication and shave biopsy of skin lesions.

Important Risk Information

In clinical studies, the most common skin reactions occurred at the application site, including redness, blanching, and swelling. These reactions were generally mild and went away by themselves. Allergic reactions such as hives, difficulty breathing, skin redness or swelling, and shock can occur. Even a used Synera patch contains a large amount of lidocaine and tetracaine. A child or pet could suffer adverse effects from chewing or swallowing a new or used Synera patch; therefore, Synera should be stored and disposed out of their reach.

Synera is contraindicated in patients with a known history of sensitivity to lidocaine, tetracaine, or local anesthetics of the amide or ester type. Synera is also contraindicated in patients with para-aminobenzoic acid (PABA) hypersensitivity and in patients with a known history of sensitivity to any other component of the product.
