Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to assess whether IW-3300 is safe and works for the treatment of interstitial cystitis/bladder pain syndrome (IC/BPS). The main question the study aims to answer is whether IW-3300 helps bladder pain and other symptoms (for example, bladder burning, pressure and discomfort). Subjects will be assigned to receive either the study drug or placebo by chance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 2, randomized, placebo-controlled, parallel-assignment, 12-week, adaptive design study to evaluate the efficacy, safety, and tolerability of IW-3300 in subjects with IC/BPS. Subjects will be randomized 1:1:1 to IW-3300 100 µg, IW-3300 300 µg, or matching placebo administered as a rectal foam. The study has 4 periods, which are the screening (up to 30 days), pretreatment (up to 21 days), study treatment (12 weeks), and follow-up periods (2 weeks) which consists of 7 onsite study visits and 1 follow-up phone call. Subjects will administer the study drug at home for 12 weeks.
