Antares Announces Initiation of Pivotal Trial of ANTUROL(TM) for the Treatment of Overactive BladderEWING, N.J.--(HSMN NewsFeed)--Antares Pharma (AMEX:AIS ), announced that it has initiated a pivotal safety and efficacy trial of ANTUROL(TM), its transdermal oxybutynin ATD(TM) gel for the treatment of overactive bladder syndrome (OAB). The three arm study will enroll approximately 600 patients for a 12-week clinical trial, conducted under a SPA (Special Protocol Assessment) and Investigational New Drug (IND) application reviewed by and filed with the U.S. Food and Drug Administration (FDA).
The randomized, double-blind, open-label, parallel, placebo controlled, multi-center trial will principally evaluate efficacy of ANTUROL when administered topically once daily for 12 weeks in patients predominantly with urge incontinence episodes. The study is expected to involve 600 patients (200 per arm) using two dose strengths (selected from the Phase II clinical trial) vs. a placebo. The primary end point of the trial will be efficacy against the placebo defined as the reduction in the number of urinary incontinence episodes experienced. Secondary end points include changes from baseline in urinary urgency, average daily urinary frequency, patient perceptions as well as safety and tolerability including skin irritation.
Jack E. Stover, President & CEO said, "We are delighted to announce the initiation of the pivotal trial of ANTUROL, our ATD(TM) gel for the treatment of overactive bladder. OAB continues to be underserved by the pharmaceutical products currently on the market due to the prevalence of side effects. ANTUROL may help to address this current medical need in a discreet, fast acting way which should also minimize many of the usual side effects. We are excited to initiate this important next step in our product development plan."
OAB affects more than 20 million adults in the U.S. (and 100 million worldwide) and is one of the fastest growing segments in the urology market. It is characterized by involuntary muscle contractions resulting in urine leakage. Symptoms include urinary frequency, urgency and urge incontinence. While OAB may occur at any age, it is most common among the elderly, affecting up to 61% of those over 65, particularly post-menopausal women. A recent SCRIP Report showed the incontinence market growing at approximately 40% per year. Treatment for OAB currently consists of oral administration of compounds such as oxybutynin, tolterodine, darifenacin, solifenacin, and trospium each of which have significant side effects, including dry mouth (seen in 70% of patients), nausea, dry eyes, and constipation. It is estimated that half of the adults suffering from OAB either are too embarrassed to discuss their symptoms or are not aware that pharmacological treatment is available. It is estimated by Cowen & Co. in their March 2006 publication that just 16% of incontinence patients were compliant with their treatment in 2005 and expected to improve modestly to only 18% in 2010.
Advanced Transdermal Delivery Systems (ATD(TM))
The ATD drug delivery platform is dedicated to the development of gels that offer a cosmetically superior option to patches, while delivering medication efficiently with less potential for skin irritation, minimizing gastrointestinal impact, as well as, the first-pass liver metabolism effect of many orally ingested drugs. Antares' ATD gels are hydro-alcoholic and contain a combination of permeation enhancers to promote rapid drug absorption through the skin following application typically to the arms, shoulders, abdomen or thighs. The Company's transdermal ATD gel system provides the options for delivering both systemically (penetrating into and through the subcutaneous tissues and then into the circulatory system) as well as locally (e.g. topically for skin and soft tissue injury, infection and local inflammation). Typically, the gel is administered daily, and is effective on a sustained release basis over approximately a 24-hour period of time.
