The purpose of this study is to determine if the combination product (URG101) is safe and effective versus its individual components (Heparin Sodium and Lidocaine Hydrochloride) for the treatment of Interstitial Cystitis/Bladder Pain Syndrome. The study is randomized and double-blinded such that neither the subject nor doctor will know which drug or placebo is received.

Official Title

A Phase 2a, Randomized, Double-Blind, Placebo-Controlled Multi-Center Single Dose Study to Evaluate the Safety and Effectiveness of URG101 Compared With the Individual Components Lidocaine and Heparin in Subjects With Interstitial Cystitis/Bladder Pain Syndrome


This is a biphasic adaptive design phase 2a, prospective, randomized, double-blind, placebo controlled, multicenter, single-dose, pharmacokinetic study designed to determine the efficacy and safety of the combination product (URG101) with its individual components (Heparin Sodium and Lidocaine Hydrochloride). The study will consist of a run-in phase of 48 subjects and an investigational phase of up to 300 subjects.

Eligible subjects exhibiting moderate to severe symptoms of bladder pain associated with their diagnosis of interstitial cystitis/bladder pain syndrome who have signed informed consent, will be screened and provisionally enrolled for intravesical treatment.

On the day of study drug administration subjects will be randomized (2:1:2:1; URG101:placebo:lidocaine:heparin) and will receive a single administration of one of four intravesical treatments in a blinded fashion, based on random assignment:

  1. URG101 (buffered lidocaine-heparin)
  2. Placebo
  3. Lidocaine Hydrocholoride buffered alone
  4. Heparin Sodium buffered alone

The study is 24 hours in duration.
