This study is testing a new drug called **VNX001** for people with bladder pain from a condition called **Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS)**. VNX001 is a mix of two medicines: **lidocaine** (a numbing medicine) and **heparin** (a blood thinner). The study compares VNX001 to lidocaine alone, heparin alone, and a **placebo** (a fake treatment). It is a **Phase 2 study**, meaning it's still early in testing. The study is **randomized** (participants are randomly assigned to different treatment groups) and **double-blind** (neither participants nor researchers know who gets which treatment). Participants will get one dose and can ask for more 24-48 hours later if needed. The study will take place in the United States with up to 180 participants.

• Participation requires only one treatment session.
• Participants must have moderate to severe bladder pain.
• Participants cannot be pregnant or on certain medications.
