Summary

Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) is a chronic and debilitating urological complex of disorders characterized by symptoms of bladder pain or discomfort, mostly upon bladder filling, and often accompanied by lower urinary tract symptoms (LUTS). This study will assess how safe and effective BOTOX (onabotulinumtoxinA) is in treating IC/BPS. Adverse events and change in disease symptoms will be evaluated. BOTOX (onabotulinumtoxinA) is an investigational drug being developed for the treatment of Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS). Study doctors randomly assign the participants to 1 of 2 groups, called treatment arms, to receive BOTOX or placebo. There is a 1 in 2 chance that participants will be assigned to placebo. Approximately 80 female participants, aged 18 to 75 years, with a diagnosis of IC/BPS will be enrolled in approximately 40 sites in the United States and Canada. Participants will receive BOTOX or placebo injected into the bladder on Day 1 and will be followed for at least 12 weeks in treatment 1. Eligible participants may request additional dose of BOTOX between Weeks 12 and 24, and will be followed for 12 weeks in treatment period 2. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.
