SAN DIEGO, May 18 /PRNewswire/ -- New study results indicated that treatment with AMITIZA(R) (lubiprostone) 8 mcg lead to significant relief of overall symptoms of Irritable Bowel Syndrome with Constipation (IBS-C). These results were presented at Digestive Disease Week (DDW) 2008, the largest annual international meeting of digestive disease specialists.
"IBS-C is a multi-symptom disorder and is one of the most common conditions seen by gastroenterologists," said William D. Chey, M.D., primary investigator of the study, University of Michigan Health System. "These data are important because they show that in studies, AMITIZA has demonstrated the ability to improve the overall symptoms reported by patients with IBS-C."
AMITIZA 8 mcg was approved by the U.S. Food and Drug Administration (FDA) on April 29, 2008 for the treatment of IBS-C in women 18 years of age and older, and has been approved since 2006 at a 24 mcg dose for the treatment of Chronic Idiopathic Constipation in adults. These data were among others presented at DDW 2008 that evaluated the effect of AMITIZA for IBS-C.
"AMITIZA is the first ClC-2 channel activator and the only widely available FDA-approved agent for the treatment of IBS-C in adult women in the United States. AMITIZA could provide overall symptom relief for the millions of appropriate patients in the U.S. who suffer from this condition," said Ryuji Ueno, M.D., Ph.D., Ph.D., founder, chairman and chief executive officer, Sucampo Pharmaceuticals (Nasdaq: SCMP). "We are pleased with the body of data on AMITIZA presented at DDW this year. Additional data presented at this meeting may help physicians better understand how to treat their patients with IBS-C."
"AMITIZA makes it possible for appropriate patients to receive a widely available FDA-approved treatment for their IBS-C," said Charles Baum, M.D., gastroenterologist and executive medical director, Gastroenterology and Internal Medicine, Takeda Pharmaceuticals North America, Inc.
Approximately 58 million Americans have Irritable Bowel Syndrome (IBS), and IBS-C accounts for approximately one-third of these cases. IBS-C is a chronic disorder characterized by abdominal discomfort or pain and changes in bowel habits including symptoms of constipation.
AMITIZA was developed by Sucampo Pharmaceuticals and is co-marketed in the U.S. by Sucampo Pharmaceuticals and Takeda Pharmaceuticals North America.
About Irritable Bowel Syndrome with Constipation (IBS-C)
IBS is a disorder characterized by symptoms including recurrent abdominal discomfort or pain, bloating, and changes of bowel habits such as constipation and/or diarrhea. There are three main types of IBS: IBS with constipation (IBS-C), IBS with diarrhea (IBS-D), and IBS with mixed constipation and diarrhea (IBS-M). In IBS-C, symptoms are present for at least 12 weeks (not necessarily consecutive) over a 12-month period. Although people with IBS-C report many of the symptoms associated with constipation, the presence of abdominal discomfort or pain is what differentiates IBS-C from chronic constipation. IBS is approximately two to two-and-a-half times more prevalent in women than men.
About AMITIZA(R) (lubiprostone) for Chronic Idiopathic Constipation and IBS-C Indication
AMITIZA(R) (lubiprostone) is indicated for the treatment of Chronic Idiopathic Constipation (24 mcg) in adults and for Irritable Bowel Syndrome with Constipation (8 mcg) in women > 18 years old.
Important Safety Information
AMITIZA is contraindicated in patients with known or suspected mechanical gastrointestinal obstruction. Patients with symptoms suggestive of mechanical gastrointestinal obstruction should be thoroughly evaluated by the treating physician to confirm the absence of such an obstruction prior to initiating AMITIZA treatment.
The safety of AMITIZA in pregnancy has not been evaluated in humans. AMITIZA should be used during pregnancy only if the benefit justifies the potential risk to the fetus. Women who could become pregnant should have a negative pregnancy test prior to beginning therapy with AMITIZA and should be capable of complying with effective contraceptive measures.
Patients taking AMITIZA may experience nausea. If this occurs, concomitant administration of food with AMITIZA may reduce symptoms of nausea. Patients who experience severe nausea should inform their physician.
AMITIZA should not be prescribed to patients that have severe diarrhea. Patients should be aware of the possible occurrence of diarrhea during treatment and inform their physician if the diarrhea becomes severe.
Patients taking AMITIZA may experience dyspnea within an hour of first dose. This symptom generally resolves within three hours, but may recur with repeat dosing. Patients who experience dyspnea should inform their physician.
In clinical trials of AMITIZA (24 mcg) in patients with Chronic Idiopathic Constipation, the most common adverse reactions (incidence > 4%) were nausea (29%), diarrhea (12%), headache (11%), abdominal pain (8%), abdominal distention (6%), and flatulence (6%).
In clinical trials of AMITIZA (8 mcg) in patients with Irritable Bowel Syndrome with Constipation, the most common adverse reactions (incidence > 4%) were nausea (8%), diarrhea (7%), and abdominal pain (5%).
