- Currently active or treated sexual transmittable diseases
- Substance abuse or any use of delta-9-tertrahydrocannabinol (THC) as assessed by a positive urine test for THC at screening
- Any clinically relevant concomitant disease (past or present) which would, in the opinion of the investigator, put the subject at risk or mask measures of efficacy

Subjects should continue these medications at that same stable dose throughout the study

5. Study Description
Brief Summary
In this study several dose levels of ASP3652, given orally for 12 weeks, will be compared with placebo in the treatment of female patients with Bladder Pain Syndrome / Interstitial Cystitis.
Detailed Description
This study consists of a screening phase, an initial 3 weeks Run-in period,
a 12 weeks Treatment period and a 2 weeks Follow-up (FU) period.
This study will investigate the efficacy and safety of a 12 week treatment with ASP3652 in female patients with Bladder Pain Syndrome / Interstitial Cystitis (BPS/IC). Different dose levels of ASP3652 will be compared with placebo. ASP3652 is administered as oral tablets. The objectives of the study are to investigate efficacy of ASP3652 in patients with BPS/IC, to assess the optimal dose of ASP3652, to investigate safety and tolerability and to investigate pharmacokinetics and pharmacodynamics of ASP3652 in patients with BPS/IC in an out-patient setting.
