Effects Of GW679769 On Bladder Nerve Function And Symptoms Of Overactive Bladder In Spinal Cord Injury Patients

See Detailed Description

This is a two-part study in which Part A will assess the effects of GW679769 after 1 dose on the function of the nerves that supply the bladder. The technique for measuring the nerves function is called Neurometry. Part B will assess the effect of repeat doses of GW679769 on the bladder nerve function. Part B will also assess the effects of the drug on overactive bladder symptoms using a three-day patient diary.

A randomized, double-blind, placebo-controlled study to evaluate the effects of GW679769 on Current Perception Threshold (CPT) following a single 150 mg dose (Part A) and to evaluate the effect of CPT and symptoms of overactive bladder following 28 days of repeat dosing with 120 mg GW679769 administered once daily (Part B) in patients with neurogenic bladder due to incomplete spinal cord injury
