LAVAL, Quebec, June 9, 2014 /PRNewswire/ -- Valeant Pharmaceuticals International, Inc. (NYSE: VRX) (TSX: VRX) today announced that that its wholly owned subsidiary, Valeant Pharmaceuticals North America LLC, received notice that the U.S. Food and Drug Administration (FDA) has approved the New Drug Application (NDA) for Jublia® (efinaconazole 10% topical solution), the first topical triazole approved for the treatment of onychomycosis of the toenails.
"We acquired Jublia® through our purchase of Dow Pharmaceutical Sciences in 2008 and advanced Jublia® from pre-IND stage through Clinical Phases 1, 2 and 3," said J. Michael Pearson, chairman and chief executive officer. "We are working quickly to get this important product launched in the U.S. and Canada in the third quarter of 2014. We anticipate favorable managed care coverage in the U.S., similar to other branded antifungal agents, with peak sales of $300-$800 million in the U.S. alone and we are also working with other regulatory agencies around the world on further approvals. This is the fourth product, sourced from our acquisition of Dow Pharmaceutical Sciences, for which we have received FDA approval – the other three being 1% clindamycin and 5% benzoyl peroxide gel (IDP 111), Acanya® and Retin-A Micro (tretinoin) Gel microsphere 0.08%. We have also filed a new treatment for acne, Onexton™, which has a PDUFA date of November 30, 2014. All these compounds came through our Dow acquisition, bringing with it the full set of R&D capabilities from preclinical through regulatory."
Onychomycosis is a common and destructive nail infection that is currently undertreated largely because of the limitations of available treatments. Currently, over-the-counter or prescription topical treatments provide limited efficacy and are often administered in conjunction with frequent debridement, or the scraping, cutting or removal of the nail. Prescription oral treatments are limited by drug interactions and serious safety concerns.
"Onychomycosis is not only embarrassing and uncomfortable, but can lead to permanent nail damage and limited mobility in the general population," said American Podiatric Medical Association Executive Director and CEO Glenn B. Gastwirth, DPM. "We welcome the approval of Jublia® and encourage people with onychomycosis of the toenails to discuss their condition with their podiatrist, or other healthcare professional to find a treatment that's right for them."
The licensor and business partner for efinaconazole, Kaken Pharmaceutical, has also agreed to supply Valeant with the finished dosage form of Jublia for the U.S. market.
Information about Jublia® (efinaconazole 10% topical solution)
Jublia® (efinaconazole 10% topical solution), is the first topical triazole antifungal agent developed for distal lateral subungual onychomycosis (DLSO).
Being a solution, Jublia® is applied daily to the nail with a novel bottle that has a built-in flow-through brush applicator. It dries quickly and there is no need to remove excess product. There are no concerns for systemic side effects such as drug-drug interactions or acute liver injury.
Jublia® has been extensively studied prior to its approval. The two positive pivotal studies that were the basis for approval were published last year in the prestigious Journal of the American Academy of Dermatology. These international studies were conducted in 1,655 subjects with onychomycosis, including subjects in Canada.
For the pivotal studies, the primary endpoint was complete cure at Week 52, which required
that the target nail show no clinical involvement and no evidence of fungus present by both KOH testing and a negative fungal culture. In Study 1, 17.8% of subjects treated with Jublia® were completely cured, compared to only 3.3% of subjects treated with vehicle. In Study 2, 15.2% of subjects treated with Jublia® were completely cured, compared to only 5.5% of subjects treated with vehicle.
Adverse events that were reported were generally mild and transient and were similar between subjects treated with Jublia® and vehicle. The most commonly reported adverse events in patients treated with Jublia® were application site dermatitis and application site vesicles.
