STUDY DESIGN AND DURATION

This irritable bowel syndrome clinical trial will be conducted as a multicenter, double-blind, randomized, placebo-controlled efficacy and safety study in adult female subjects with IBS-D. The 3-period study design consists of a screening period of up to 30 days, a 4-week treatment period, and a 4-week follow-up period. The duration of estimated subject-participation time for the study is 12 weeks.

BACKGROUND & RATIONALE

Irritable bowel syndrome (IBS) is a functional gastrointestinal (GI) disorder characterized by abdominal pain or discomfort and altered bowel habits without identifiable organic disease to explain the symptoms. The prevalence of IBS in North America is approximately 10 to 15% of the adult population with an approximately 2-fold higher incidence for women. Although it is not life threatening, the symptoms of IBS are among the most common reasons for visits to primary care physicians and gastroenterologists due to the serious impact on the patient's quality of life.

Patients are classified into the following 4 subtypes by the stool pattern using the Bristol Stool Scale (BSS); IBS with diarrhea (IBS-D), IBS with constipation (IBS-C), mixed IBS (IBS-M) and unsubtyped IBS. The predominance of each subtype varies in reports from equal distribution of IBS-D, IBS-C and IBS-M to higher IBS-D or IBS-M type occurrence. A significant unmet need in the management of IBS is discovery of a safe and effective treatment that relieves pain, reduces bowel motility dysfunction, and improves global symptoms.

PRIMARY OBJECTIVES

The primary objective of the study is to explore efficacy of a new IBS drug in abdominal pain or stool symptoms (ie, number and consistency of stool) in female subjects with IBS-D.

SECONDARY OBJECTIVES

The secondary objectives of the study include:
To explore efficacy of this new drug in stool urgency, abdominal discomfort, adequate
To investigate the safety and tolerability of this new drug in female subjects with IBS-D
To assess the PK of this new drug in female subjects with IBS-D relief of IBS symptoms or IBS-related pain and QoL in female subjects with IBS-D
