Summary

The purpose of this research study is to identify the optimal usage of Onabotulinumtoxin A in interstitial cystitis. Onabotulinumtoxin A, more commonly known by the trade name Botox®, is a medication that comes from the bacteria Clostridium botulinum. It works by blocking the release of the neurotransmitter acetylcholine(a chemical messenger that carries signals between nerve cells and other cells in the body). Blocking that neurotransmitter results in decreased muscle activity.

Awards & Highlights

All Individual Drugs Already Approved
Therapies where all constituent drugs have already been approved are likely to have better-understood side effect profiles.
No Placebo-Only Group
All patients enrolled in this study will receive some form of active treatment.
Pivotal Trial

Trial Design

2Treatment groups
Experimental Treatment
Active Control
Group I: Botox upper aspect trigoneExperimental Treatment2 Interventions
Subjects in the experimental cohort will receive a one time dose of 100 units of Onabotulinumtoxin A diluted in 10 mL of preservative free normal saline and injected in 1.0 mL boluses in a set pattern across the upper aspect of the trigone of the urinary bladder.
Group II: botox periphery of trigoneActive Control2 Interventions
Each group will receive a total of 100 units of botox spread out among 10 separate injections. Subjects in the control group will have 10 injections made about the periphery of the trigone. The control cohort will receive a one time dose of Onabotulinumtoxin A using the same dilution and number of boluses, but boluses will be administered at random sites on the posterior bladder wall (excluding the trigone).
