`
`RALEIGH, N.C. Salix Pharmaceuticals, Ltd. reported that initial subjects have been enrolled and dosed in three
`latestage trials designed to evaluate XIFAXAN® for the treatment of C. difficileassociated diarrhea (CDAD),
`irritable bowel syndrome (IBS) and hepatic encephalopathy (HE). Additionally, initial subjects have been enrolled
`and dosed in a latestage trial designed to evaluate an 1100 mg tablet formulation of COLAZAL® for the
`treatment of mildly to moderately active ulcerative colitis, and patient enrollment continues in two latestage
`trials designed to evaluate granulated mesalamine for the maintenance of remission of ulcerative colitis. The
`company intends to pursue label extensions for XIFAXAN for the indications noted above, as well as a
`formulation line extension for the new COLAZAL Tablet and an approval for granulated mesalamine.
`
`XIFAXAN
`C. difficileAssociated Diarrhea (CDAD)
`XIFAXAN (rifaximin), dosed 400 mg three times daily, is being investigated in a vancomycin comparator, 300
`subject Phase III trial to evaluate the efficacy and safety of XIFAXAN for the treatment of CDAD.
`
`Research by Ciaran Kelly, MD, Harvard School of Medicine; Dan Gerding, Hines VA Hospital and other
`investigators provides the theoretical basis for the development of XIFAXAN as a treatment for CDAD. Poster
`presentations of recent preclinical work by Kelly and Gerding were presented December 1619, 2005 at the
`Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC) in Washington, D.C. Results of a
`hamster model study of CDAD, conducted by Kelly, demonstrated that rifaximintreated and vancomycin
`treated, CDADchallenged animals achieved similar survival rates. Due to the common recurrence of CDAD in
`the clinical setting, the hamsters were followed after the discontinuation of treatment. Seventyfive percent of
`animals treated with vancomycin developed recurrent C. difficile cecitis (inflammation of the cecum) within 21
`days of stopping therapy whereas none of the rifaximintreated animals had such a relapse. Results of a
`comparison of rifaximin, rifalazil, metronidazole and vancomycin to investigate the in vitro activity of these
`agents against toxigenic C. difficile clinical isolates, conducted by Gerding, demonstrated that rifaximin and
`rifalazil were the most active agents.
`
`Clostridium difficile, or C. difficile, is the most common causative agent of diarrhea among institutionalized
`patients. Often the administration of antibiotics, especially broadspectrum antibiotics, disrupts the normal gut
`bacterial flora and increases the concentration of C. difficile. The presence of increased C. difficile can produce
`symptoms ranging from mild diarrhea to lifethreatening colitis.
`
`Irritable Bowel Syndrome (IBS)
`XIFAXAN, dosed either 275 mg, 550 mg or 1100 mg twice daily, is being investigated in a placebocontrolled,
`525subject Phase IIb trial to evaluate the efficacy and safety of XIFAXAN for the treatment of diarrhea
`associated IBS.
`
`In November 2005 at the American College of Gastroenterology Annual Scientific Meeting, Mark Pimentel,
`CedarsSinai Medical Center, presented the findings of a randomized, doubleblind, placebocontrolled
`investigation of XIFAXAN in the treatment of IBS. In the 87subject study, XIFAXANtreated subjects
`demonstrated a statistically significant improvement versus placebotreated subjects, and a statistically
`significant number of XIFAXANtreated subjects demonstrated a greater than 50 percent global improvement
`compared to placebotreated subjects. This proofofconcept work provided essential information utilized in the
`design of the company's development program for IBS.

`XIFAXAN® Trials Initiated in C. difficileAssociated Diarrhea, Irritable Bowel Syndrome and Hepatic Encephalopathy
`3/5/2015
`IBS is a bowel disorder characterized by altered bowel function and symptoms including abdominal pain,
`bloating, constipation and diarrhea. This chronic disorder impacts up to 20 percent of the U.S. population, and
`yet, despite its high prevalence, the cause of IBS remains unknown. Current treatments provide only temporary
`symptom relief and do not treat the underlying cause of the symptoms. Recently, bacteria specifically an
`overgrowth of bacteria in the small intestine have been proposed as a significant causative agent in IBS.
`
`Hepatic Encephalopathy (HE)
`XIFAXAN, dosed 550 mg twice daily, is being investigated in a placebocontrolled, 250subject Phase III trial to
`evaluate the efficacy and safety of XIFAXAN for the prevention of hepatic encephalopathy.
`
`Hepatic encephalopathy is a metabolicneurophysiologic syndrome associated with advanced liver disease.
`Symptoms are generally believed to result from the inability of the liver to remove toxic products in the gut.
`These toxic products primarily ammonia produced by the intestinal metabolism of nitrogenous compounds
`are able to pass the blood brain barrier and ultimately reach the central nervous system to produce HE
`symptoms. Neuropsychiatric and neuromuscular symptoms range from mild personality changes, memory loss,
`tremor and asterixis to coma and death.
`
`COLAZAL
`COLAZAL (balsalazide disodium), formulated as an 1100 mg tablet, dosed three tablets twice daily, is being
`investigated in a multicenter, placebocontrolled, doubleblind, randomized trial. This Phase III trial, involving
`225 patients, is designed to evaluate the efficacy and safety of 1100 mg balsalazide disodium tablets for the
`treatment of mildly to moderately active ulcerative colitis.
`
`GRANULATED MESALAMINE
`Granulated mesalamine is formulated to deliver mesalamine by means of dualrelease granules to the distal
`ileum and colon. Granulated mesalamine is being investigated in two 300subject, multicenter, placebo
`controlled, doubleblind, randomized trials. Enrollment is ongoing in these Phase III trials designed to evaluate
`the efficacy and safety of granulated mesalamine, dosed four 375 mg tablets once daily, for the maintenance of
`remission of ulcerative colitis.
`
`OTHER
`A pediatric trial with COLAZAL is currently ongoing. Enrollment in the trial is anticipated to be complete during
`the first quarter of 2006. A trial with XIFAXAN to assess blood concentrations of a new pediatric suspension is
`being planned for 2006.
`
`New Drug Applications (NDAs) for INKP102, the nextgeneration tablet purgative product owned by subsidiary
`InKine; and NRL944, the liquid PEG purgative product acquired recently from Norgine, are under review at the
`U.S. FDA. As required by the Prescription Drug User Fee Act (PDUFA), results of the FDA review are due in mid
`March 2006 for INKP102 and lateApril 2006 for NRL944.
