APRISO(TM) Granted FDA Marketing Approval for Maintenance of Remission of Ulcerative ColitisAPRISO(TM) First and Only 5-ASA With Intellicor(TM) Extended-Release Delivery and 24-Hour Protection From Flare-Ups in a Once-Daily Dose
RALEIGH, NC--(Healthcare Sales & Marketing Network)--Nov 3, 2008 -- Salix Pharmaceuticals, Ltd. (NasdaqGS:SLXP ) today announced that the U.S. Food and Drug Administration (FDA) has granted marketing approval for APRISO(TM) (mesalamine) extended-release capsules 0.375 g. APRISO is a locally-acting aminosalicylate indicated for the maintenance of remission of ulcerative colitis (UC) in adults. APRISO is the first and only mesalamine product approved by the FDA for once-a-day dosing for the maintenance of remission of ulcerative colitis. Additionally, APRISO is the first and only 5-ASA with Intellicor(TM) extended-release delivery technology. The Company expects to launch APRISO to physicians during the first quarter of 2009. APRISO is patent protected until 2018.
Bill Forbes, Pharm. D., Vice President, Research and Development, and Chief Development Officer, Salix, stated, "APRISO is an important new once-daily treatment option that encourages compliance in ulcerative colitis patients and provides effective long-term protection from ulcerative colitis flare-ups. A major goal of UC therapy is to prevent relapse which may decrease the risk of disease progression. APRISO accomplishes this goal through the combination of an enteric pH-dependent coating which provides for a delayed release starting at a pH of 6.0 and a polymer matrix core, which provides for extended release. This patented delivery technology is designed to distribute the active ingredient beginning in the small bowel and continuing throughout the colon. Previous generation pH-dependent 5-ASA treatment options provide for release of the active ingredient starting at a pH of 7.0. According to published data, many people never reach a pH of 7.0 in their small or large intestine. APRISO represents a new and important advancement in 5-ASA drug delivery."
The approval is based on results from two randomized, double-blind, placebo-controlled multi-center, multi-national studies totaling 562 adults in remission from ulcerative colitis. The studies showed that APRISO was more effective than placebo in maintaining long-term remission for six months. In both studies, the proportion of patients who remained relapse-free at six months was greater for APRISO than for placebo.
In these studies APRISO offered clinically-proven efficacy in extending both remission and relief of UC symptoms:
-- Maintained remission for six months in 7 out of 10 UC patients in two clinical trials and
-- Sustained improvement in rectal bleeding and bowel movement frequency.
APRISO's patented Intellicor(TM) delivery system is the first and only to combine delayed and extended 5-ASA release.
-- Unlike tablets, APRISO's gelatin outer capsule quickly dissolves in the stomach to disperse microgranules into the digestive tract.
-- Next, a delayed-release coating on the microgranules dissolves at pH 6.0 or higher.
-- Last, an inner polymer matrix core controls the extended release of mesalamine to provide drug distribution throughout affected areas.
About Mesalamine Granules
APRISO(TM) is a locally-acting aminosalicylate indicated for the maintenance of remission of ulcerative colitis in patients 18 years and older. APRISO is contraindicated in patients with hypersensitivity to salicylates, aminosalicylates, or to any of the components of APRISO capsules. The recommended dose of APRISO is four 0.375 g capsules once daily in the morning (1.5 g/day) with or without food. Because dissolution of the coating of APRISO granules depends on pH, APRISO should not be coadministered with antacids. Patients with phenylketonuria should be aware that APRISO contains aspartame, equivalent to 0.56 mg of phenylalanine. In two well-controlled clinical trials, the most common treatment-related adverse events occurring in greater than 3% of adult patients taking 1.5 g/day of APRISO (versus placebo) were headache (11% vs. 8%), diarrhea (8% vs. 7%), upper abdominal pain (5% vs. 3%), nausea (4% vs. 3%), nasopharyngitis (4% vs. 3%), influenza and influenza-like illness (4% vs. 4%) and sinusitis (3% vs. 3%).
Salix acquired rights to market APRISO in the U.S. from Dr. Falk Pharma GmbH of Freiburg, Germany. Mesalamine granules have been approved in Germany since 2001 for the treatment of symptoms related to inflammatory bowel disease. In addition, consistent with the FDA-approved labeling, once-daily dosing of mesalamine granules is currently approved via the mutual recognition procedure in Austria, Belgium, Denmark, Finland, Greece, Ireland, Luxemburg, Netherlands, Norway, Portugal, Sweden, Spain and the UK.
About Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disease of the colon or large intestine. The inflammation usually begins in the rectum and lower colon, but it may also involve the entire colon. Because the inflammation makes the colon empty frequently, symptoms typically include diarrhea (sometimes accompanied by blood) and often abdominal pain. About five percent of people with ulcerative colitis will develop colorectal cancer.
Patients with ulcerative colitis may experience periods of remission (times when the symptoms go away) that can last for months or years. However, most patients' symptoms eventually return. Active therapy is treatment given to treat ulcerative colitis symptoms when they are active. Maintenance therapy refers to treatment given to patients to enable them to stay in remission, and to maintain their health in a disease-free, or limited-disease, state. Maintenance medications must be taken for a prolonged period of time.
