Nuvo Research® Announces Grant of United States Patent for Topical Onychomycosis Formulation
August 11, 2015
MISSISSAUGA, ON, Aug. 11, 2015 /CNW/ - Nuvo Research Inc. (TSX:NRI), a specialty pharmaceutical company with a diverse portfolio of topical and immunology products, today announced that the United States Patent and Trademark Office has granted a new U.S. patent number 9,084,754 ('754 Patent). The '754 Patent claims cover highly permeating topical formulations of terbinafine, an antifungal drug, and methods for treating onychomycosis. Onychomycosis is a prevalent fungal infection of the nail. The '754 Patent will expire on March 8, 2031. Related patents have been issued in Australia and are pending in Canada, China, Europe, Japan and the United States. Nuvo has pioneered formulations utilizing chemical penetration enhancers in other topically-applied drug products including the Company's lead products, Pennsaid® and Pennsaid 2%.
"Onychomycosis is an uncomfortable and embarrassing condition that affects approximately 10% of the population," said Dan Chicoine, Nuvo's Chairman and Co-CEO. "Existing therapies have side effects or limited efficacy creating a significant market opportunity for a topical product that can safely eradicate the fungal infection. These patents afford Nuvo another avenue to realize value from our investments and scientific accomplishments in delivering drugs into or through skin and nails. Our strategy is to make this formulation available for out-licensing collaborations with partners who will fund completion of the development program."
Onychomycosis (also known as dermatophytic onychomycosis or tinea unguium) is a fungal infection of the nail. It is the most common disease of the nails and constitutes about half of all nail abnormalities. This condition may affect toenails or fingernails, but toenail infections are particularly common. It occurs in about 10 percent of the adult population.
Pennsaid is used to treat the signs and symptoms of osteoarthritis (OA) of the knee(s). The drug combines a transdermal carrier (containing DMSO) with 1.5% diclofenac sodium, a non-steroidal anti-inflammatory drug (NSAID) and delivers the active drug through the skin directly to the site of inflammation and pain. Following FDA approval of Pennsaid 2%, Pennsaid is no longer marketed in the U.S. effective January 1, 2015. It is currently marketed in Canada by Paladin Labs Inc. and marketed under license and/or distribution agreements in Greece, Italy and the U.K.
About Pennsaid 2%
Pennsaid 2% is a topical product containing 2% diclofenac sodium compared to 1.5% for original Pennsaid. It is approved in the U.S. for pain of OA of the knee(s). It is more viscous than Pennsaid, is supplied in a metered dose pump bottle and has been approved in the U.S. for twice daily dosing compared to four times a day for Pennsaid. Pennsaid 2% is protected by multiple U.S. patents that are listed in the U.S. Food and Drug Administration's (FDA's) Approved Drug Products with Therapeutic Equivalence Evaluations database or Orange Book. Pennsaid 2% has not yet received regulatory approval outside of the U.S. Patents protecting Pennsaid 2% have been issued or are pending in multiple major international territories.
