- •a post-void residual (PVR) >200 mL.
- •subject has a known currently symptomatic urethral diverticulum.
- •subject has genital tract condition or pelvic pathology (e.g., post-partum, post-pelvic surgery, post-hysterectomy) that may complicate diagnosis and the evaluation of pelvic pain and urinary symptoms. Note: A history of a Cesarean section is not a reason for exclusion.
- •subject has a known currently symptomatic bladder or ureteral calculi.
- •subject currently has cystitis (radiation cystitis, Bacillus Calmette-Guérin-induced cystitis, bacterial/tuberculous cystitis, cyclophosphamide cystitis) or has had a documented symptomatic bacterial cystitis within the last 1 month prior to the screening visit. In case of bacterial cystitis (UTI), the subject can be re-screened 1 month after successful treatment.
- •subject has currently clinically significant urinary bladder abnormalities (e.g., bladder mass, bladder stone, bladder diverticulum, small contracted end-stage bladder), except for abnormalities associated with BPS/IC.

结局指标
主要结局
Change from Baseline in Average Mean Daily Pain (MDP) Score at Week 12
时间窗: Baseline and Week 12
Participants will record their MDP each day in the evening into an e-diary. The MDP is the average pain experienced over the past 24 hours. The average MDP is the mean of daily assessments of MDP in the week prior to the visit with at least 5 recordings in that week. MDP is measured using an 11-point Numerical Rating Scale (NRS) ranging from 0 (no bladder pain) to 10 (worst imaginable bladder pain). A negative change indicates a reduction/improvement from baseline.
