MISSISSAUGA, ON, June 30, 2011 /PRNewswire/ - Nuvo Research Inc. (TSX: NRI), a specialty pharmaceutical company dedicated to building a portfolio of products primarily for the treatment of pain, today announced receipt from Mallinckrodt Inc., a Covidien company (Covidien), of top-line results from a Phase 2 study conducted by Covidien, of twice-daily administration of PENNSAID® Viscous Solution (topical diclofenac sodium viscous solution) 2% w/w, previously referred to as PENNSAID Gel.  The study met its primary endpoint of reducing osteoarthritis (OA) pain greater than a placebo vehicle control (p=0.042).

"We are pleased with the top-line results of this Phase 2 clinical trial for PENNSAID Viscous Solution," said Dr. Bradley S. Galer, President, Pain Group of Nuvo Research. "We look forward to receiving the detailed results from this study in the future and working with Covidien to obtain FDA approval for PENNSAID Viscous Solution."

The Phase 2 study was a four-week, two-arm, double-blind, vehicle-controlled, parallel, randomized trial. The primary endpoint was the effect of PENNSAID Viscous Solution vs. placebo vehicle control on Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC®) pain from baseline to four weeks. The study enrolled 259 subjects who were either administered PENNSAID Viscous Solution or a placebo vehicle control for the duration of the study.  There were no significant differences in subject retention, demographics or baseline characteristics between the two study arms.  The most common adverse event in both groups was application site dryness (21.5% and 21.7%).

IMPORTANT RISK INFORMATION ABOUT PENNSAID

Cardiovascular Risk

  • Non-steroidal 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.
