About this trial

This is an open-label study that will enroll participants with Interstitial Cystitis / Bladder Pain Syndrome (IC/BPS).

The study will assess PRN (as needed) dosing of up to 6 intravesical (via catheter) doses of VNX001 (study drug) to treat acute instances of moderate to severe bladder pain over a 14-day period. The main aim of the study is to tally the number of doses and assess pain before and after doses. The study will review the safety and tolerability of VNX001.

Participants will need to attend up to seven (7) clinic visits (1 for screening and up to 6 visits for VNX001 dosing) or at least one (1) clinic visit (for a combined screening/dosing visit) and 5 telephone visits over the course of 14 days. Participants will also be asked complete a diary or telephone call each day of the study, in order to record bladder pain, urinary urgency, side effects, and medications taken.

Trial outcomes

Primary outcomes

1

Frequency of PRN intravesical administrations of VNX001

Time frame
14 Days

Secondary outcomes

1

Change in bladder pain from first dose baseline to 1, 2, 6, 12, and 24 hours post-dose

Average absolute change and average percentage change in bladder pain from baseline to 1, 2, 6, 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.

Time frame
Through 24 Hours
2

Change in bladder pain after each repeat dose to 1, 6, 12, and 24 hours post-dose

Average absolute change and average percentage change in bladder pain from after each repeat dose to 1, 6, 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.

Time frame
Through 24 Hours
3

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

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.

Time frame
Through 24 Hours
4

Change in the Patient Overall Rating of Improvement of Symptoms (PORIS) questionnaire

Change in percentage of subjects achieving ≥ 50% improvement in pain, urgency and overall improvement using the PORIS questionnaire at 1, 12, and 24 hours post-dose. The PORIS questionnaire is an assessment of the subject's condition after treatment compared to before treatment. Subjects will be asked 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).
