  Purpose
This study will test the hypothesis that GW427353, a beta-3 adrenergic agonist, retards the emptying of the colon and increases total colonic transit time.

Condition Intervention Phase
Irritable Bowel Syndrome (IBS) Drug: Placebo Drug: Solabegron (GW427353) Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Diagnostic
Official Title: An Exploratory Phase I Study in Healthy Volunteers of GI Transit Following Administration of the ß3-Adrenergic Receptor Agonist, Solabegron (Study B3I106248)

Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • colonic emptying rate by radiolabeled scintigraphy [ Time Frame: throughout the study ]

Secondary Outcome Measures:

Enrollment: 36
Study Start Date: October 2006
Intervention Details:
    Drug: Placebo Drug: Solabegron (GW427353)
    Other Name: Placebo
