DUBLIN, July 10, 2017 /PRNewswire/ -- Allergan plc (NYSE:AGN) announced additional results of a prespecified prospective pooled subgroup analysis from the two Phase 3 studies (IBS-3001 and IBS-3002), which evaluated the efficacy and safety of Viberzi in nearly 2,500 IBS-D patients, of whom 36 percent reported use of loperamide in the 12 months prior to study randomization. These data demonstrate Viberzi® (eluxadoline) safely and effectively treats the IBS-D symptoms of abdominal pain and diarrhea irrespective of prior use of loperamide.1 These analyses also demonstrated efficacy and safety in patients with loperamide rescue medication use compared to the overall population during the two studies. The American Journal of Gastroenterology published these results, Eluxadoline Efficacy in IBS-D Patients Who Report Prior Loperamide Use, in the June issue.
"Irritable bowel syndrome with diarrhea is a health concern that affects approximately 16 million people,2,3 and despite the use of over-the-counter medications, many patients experience debilitating symptoms associated with the syndrome and often cycle through several options with little to no relief," said lead author Brian E. Lacy, MD, PhD, Division of Gastroenterology and Hepatology, Dartmouth-Hitchcock Medical Center. "These results further support the use of eluxadoline to provide significant and effective relief from abdominal pain and diarrhea, two of the most common symptoms affecting those suffering with IBS-D, regardless of prior treatment experience."
Among patients who reported prior loperamide use with inadequate symptom control, a significantly greater proportion of patients treated with eluxadoline were composite responders over weeks 1-12 compared with those treated with placebo (eluxadoline 100 mg: 27.0 percent (P<0.001) and 75 mg: 26.3 percent (P=0.001) versus placebo 12.7 percent). The most commonly reported adverse events (AEs) are consistent with the known safety profile of eluxadoline, which were nausea, abdominal pain, constipation and headache.1
"These results continue to build on the robust clinical profile that has already been established, and further underscores Viberzi® as a safe and effective treatment option for patients suffering from inadequate symptom control associated with a commonly used treatment for IBS-D," said David Nicholson, Ph.D., Chief Research & Development Officer, Allergan.
About Viberzi® (Eluxadoline)
Eluxadoline is marketed by Allergan in the United States as Viberzi® (eluxadoline) CIV. Viberzi® is a twice daily, oral medication used to treat adults with irritable bowel syndrome with diarrhea (IBS-D). Viberzi® has mixed opioid receptor modulator activity; it is a mu- and kappa-opioid receptor agonist and a delta-opioid receptor antagonist. Viberzi acts locally in the gut and is thought to decrease visceral hypersensitivity and control GI motility, based on nonclinical studies. Viberzi® is indicated for the treatment of IBS-D in adult men and women. Please also see full Prescribing Information: https://www.allergan.com/assets/pdf/viberzi_pi.
IMPORTANT SAFETY INFORMATION
VIBERZI is contraindicated in patients:
- Without a gallbladder.
- With known or suspected biliary duct obstruction, or sphincter of Oddi disease or dysfunction; a history of pancreatitis; or structural diseases of the pancreas.
- With alcoholism, alcohol abuse, alcohol addiction, or who drink more than 3 alcoholic beverages per day.
- With severe hepatic impairment.
- With a history of chronic or severe constipation or sequelae from constipation, or known or suspected mechanical gastrointestinal obstruction.
Warnings and Precautions
- Pancreatitis, with or without sphincter of Oddi spasm, has been reported in patients taking either the 75 mg or 100 mg dosage of VIBERZI, including serious cases resulting in hospitalization, primarily in patients without a gallbladder. Fatal cases have also been reported in patients without a gallbladder. VIBERZI is contraindicated in patients without a gallbladder. Most of the reported cases of serious pancreatitis occurred within a week of starting treatment with VIBERZI and some patients developed symptoms after one to two doses.
- In patients with a gallbladder, evaluate a patient's alcohol intake prior to starting VIBERZI. Instruct patients to avoid chronic or acute excessive alcohol use while taking VIBERZI. Monitor for new or worsening abdominal pain that may radiate to the back or shoulder, with or without nausea and vomiting. Instruct patients to immediately stop VIBERZI and seek medical attention if they experience symptoms suggestive of pancreatitis such as acute abdominal or epigastric pain radiating to the back or shoulder associated with elevations of pancreatic enzymes with or without nausea and vomiting.
Sphincter of Oddi Spasm:
- There is a risk of sphincter of Oddi spasm, resulting in pancreatitis or hepatic enzyme elevation associated with acute abdominal pain (eg, biliary-type pain) in patients taking VIBERZI. Serious adverse reactions of sphincter of Oddi spasm with or without pancreatitis resulting in hospitalization have been reported, primarily in patients without a gallbladder. Cases of serious sphincter of Oddi spasm occurred within a week of starting treatment with VIBERZI and some patients developed symptoms after one to two doses.
- Instruct patients to immediately stop VIBERZI and seek medical attention if they experience symptoms suggestive of sphincter of Oddi spasm such as acute worsening of abdominal pain that may radiate to the back or shoulder with or without nausea or vomiting, associated with elevations of pancreatic enzymes or liver transaminases. Do not restart VIBERZI in patients who developed biliary duct obstruction while taking VIBERZI.
- The most commonly reported adverse reactions (incidence >5% and greater than placebo) were constipation, nausea, and abdominal pain.
