A Study To Investigate Tanezumab In Patients With Interstitial Cystitis/ Painful Bladder Syndrome

This study has been terminated.
(See termination reason in detailed description.)

Information provided by (Responsible Party):
Pfizer
ClinicalTrials.gov Identifier:
NCT00999518
First received: October 20, 2009
Last updated: August 23, 2012
Last verified: August 2012
  Purpose
In a previous study in patients with interstitial cystitis/ painful bladder syndrome (IC/PBS), tanezumab has shown to be efficacious in relieving the pain associated with IC/PBS, as well as some effect on reducing urinary urgency. Only one dose was studied, and tanezumab was well tolerated. In this study, the hypothesis being tested is that tanezumab will show efficacy at several doses on reducing pain with sufficient tolerability. Tanezumab's safety will also be assessed at different dose levels
