Antares Pharma Announces FDA Acceptance of Anturol(R) NDA for FilingEWING, N.J.--(Healthcare Sales & Marketing Network)-- Antares Pharma, Inc. (NYSE Amex: AIS) today announced the New Drug Application (NDA) for Anturol® Gel in patients with overactive bladder (OAB) was accepted for filing for review by the U.S. Food and Drug Administration (FDA). Anturol is an oxybutynin gel incorporating Antares’ ATD Gel technology.
The FDA has assigned a Prescription Drug User Fee Act (PDUFA) date of December 8, 2011, ten months from the official NDA filing. The PDUFA date is the target date for the FDA to complete its review of the NDA.
“The FDA’s acceptance of the NDA filing is an important milestone in the review process to secure approval from the FDA for commercial distribution of Anturol. We look forward to working with the FDA in their ongoing review of Anturol,” said Kaushik J. Dave R.Ph., Ph. D., MBA, Senior VP Product Development of Antares Pharma.
The Anturol NDA submission is supported by data from a Phase 3 randomized, double-blind, placebo-controlled clinical trial involving 600 patients with OAB. In the 12-week study, patients treated with Anturol 56 mg daily or 84 mg daily experienced a significant decrease in OAB symptoms versus placebo, including the number of urinary incontinence episodes per day. Anturol was well tolerated in the study with no reported serious treatment-related adverse events. Anticholinergic side effects such as dry mouth and constipation were low and no increase in CNS side effects was seen compared to placebo. The study was conducted under a Special Protocol Assessment (SPA) by the FDA.
"The FDA’s acceptance for filing of the NDA for Anturol, Antares Pharma’s first NDA, is another notable achievement for the Company resulting from the dedicated efforts of the entire Antares team. This is an important accomplishment in the continued execution of our product focused strategy,” said Paul K. Wotton Ph.D., President and Chief Executive Officer.
Anturol is an oxybutynin gel based on the ATD Gel technology platform which is a clear, odorless, hydroalcoholic gel that provides for delivery of oxybutynin in a non-patch transdermal form. The ATD technology is also used in Elestrin®, an FDA approved product for hormone replacement therapy in postmenopausal women. It has been well recognized that transdermal delivery of drugs including oxybutynin is a safe and effective way of delivering certain drugs that undergo first pass metabolism. By delivering oxybutynin transdermally, first-pass gastric and hepatic metabolism is avoided, which is believed to result in lower anticholinergic side effects such as dry mouth and constipation compared to orally administered treatments. These side effects are believed to account for a significant level of patient non-compliance among existing oral OAB treatments.
About Overactive Bladder
OAB, also called urge incontinence, is a condition marked by a sudden need to urinate that can happen at any time whether or not the bladder is full. OAB is typically caused when the smooth muscle of the bladder undergoes involuntary contractions and may result in uncontrolled leakage. OAB is defined as urgency, with or without urge incontinence and usually includes frequency and nocturia (waking up one or more times during the night to urinate). According to published reports it is estimated that more than 30 million Americans have OAB, and while it can happen at any age is more prevalent among older individuals. It is more common than both diabetes and asthma. According to IMS the annual OAB prescription market in the United States is valued at approximately $2.0 billion.
