Brief Summary

This is a Phase 2, prospective, randomized, double-blind, placebo-controlled, multi-center, single-dose, pharmacodynamic study designed to evaluate the efficacy and safety of the combination product (VNX001) versus placebo and its individual components (heparin sodium and lidocaine hydrochloride (HCl)) for the reduction of bladder pain in patients with interstitial cystitis (IC) / bladder pain syndrome (BPS).

Detailed Description

This is a Phase 2, prospective, randomized, double-blind, placebo-controlled, multi-center, single-dose, pharmacodynamic study designed to evaluate the efficacy and safety of the combination product (VNX001) versus placebo and its individual components (heparin sodium and lidocaine hydrochloride) for the reduction of bladder pain in patients with IC/BPS. The study will enroll a target of 120 subjects, with a maximum of 180 subjects, across approximately 12 sites in the United States. Each study subject will receive a single dose of VNX001, placebo (alkalinized phosphate buffer), alkalinized lidocaine, or alkalinized heparin by random assignment. The randomization ratio will be 3:1:3:1, respectively. At 24-48-hours post-dose, all subjects will be given the option of requesting a single dose of VNX001.

Primary Outcome Measures
NameTimeMethod
Sum of bladder pain intensity differences from baseline to 12 hours post-dose (SPID-12)12 hours

A measure of the sum of bladder pain intensity differences from baseline to 12 hours post-dose (SPID-12), as determined using an 11-point numerical rating scale (NRS) for bladder pain. The 11-point NRS for bladder pain is a scale from 0 to 10, with 0 indicating no bladder pain and 10 indicating the worst imaginable bladder pain.

Secondary Outcome Measures
NameTimeMethod
Sum of bladder pain intensity differences from baseline to 6, 10, and 24 hours post-dose (SPID-6, SPID-10, and SPID-24, respectively)6, 10, or 24 hours

A measure of the sum of bladder pain intensity differences from baseline to 6, 10, and 24 hours post-dose (SPID-6, SPID-10, and SPID-24, respectively), as determined using an 11-point numerical rating scale (NRS) for bladder pain. The 11-point NRS for bladder pain is a scale from 0 to 10, with 0 indicating no bladder pain and 10 indicating the worst imaginable bladder pain.

Change in bladder pain from baseline to 1, 4, 8, 12, and 24 hours post-dose1, 4, 8, 12, and 24 hours

Average absolute change and average percentage change in bladder pain from baseline to 1, 4, 8, 12, and 24 hours post-dose, as determined using an 11-point numerical rating scale (NRS) for bladder pain. The 11-point NRS for bladder pain is a scale from 0 to 10, with 0 indicating no bladder pain and 10 indicating the worst imaginable bladder pain.

Change in Question 3 of the Patient Overall Rating of Improvement of Symptoms (PORIS) questionnaire1, 10, and 24 hours

Percentage of subjects achieving ≥ 50% improvement in Question 3 of the PORIS questionnaire at 1, 10, and 24 hours post-dose. The PORIS questionnaire is an assessment of the subject's condition after treatment compared to before treatment. In particular, Question 3 of the PORIS questionnaire asks subjects to select the category that best describes the overall change in their condition compared to before receiving study medication; the choices are: worse, no better (0% improvement), slightly improved (25% improvement), moderately improved (50% improvement), greatly improved (75% improvement), or symptoms gone (100% improvement).
