A Randomized Study Comparing Placebo and ASP3652 in the Treatment of Women With Bladder Pain Syndrome / Interstitial Cystitis (BPS/IC)
A Randomized Study Comparing Placebo and ASP3652 in the Treatment of Women With Bladder Pain Syndrome / Interstitial Cystitis (BPS/IC)
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.
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.
Inclusion Criteria:

 -  Has previously been diagnosed with BPS/IC; i.e., pelvic pain, pressure or discomfort
 perceived to be related to the urinary bladder accompanied by at least one other
 urinary symptom such as persistent urge to void or frequency, for at least 3 months
 prior to screening in absence of urinary infection or other obvious pathology or
 identifiable causes

 -  Has at enrolment a score of 4 or greater on the 11-point (0-10) NRS for average pain
 over the previous week, which is item 4 of the F-GUPI

 -  Has a mean pain score of 4.0 or greater on the 11-point (0-10) NRS for daily assessed
 pain (item 4 of F-GUPI-24H) over the last 7 days prior to randomization

 -  Is willing to comply with study requirements such as completing the questionnaires and
 diaries and attend all study visits and practicing birth control

 Exclusion Criteria:

 -  Undergone a cystoscopy with hydrodistension or undergone Botox injections in the
 bladder within 6 months prior to screening

 -  Use of pentosan polysulphate sodium within 4 weeks prior to screening

 -  Any intravesicular pharmacological treatment or other interventions for BPS/IC or
 bladder, urethral, ureteral, pelvic or peri-pelvic invasive procedure within 3 months
 prior to screening

 -  Cystitis or documented symptomatic bacterial cystitis in the last 3 months prior to
 screening

 -  Lower urinary tract malignancy, such as positive (micro) hematuria in urine sediment

 -  Neurologic disease or defect affecting bladder function or symptomatic urethral
 diverticulum or any post-partum or surgery related genital tract conditions,
 symptomatic bladder or ureteral calculi or Post Void Residual volume greater than 150
 mL

 -  Clinically significant abnormalities observed during cystoscopy or on transabdominal
 ultrasound

 -  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

 -  Symptoms of depression, defined as a Center for Epidemiological Studies Depression
 Scale score of 27 or more

 -  Use of steroids, immunomodulators, cytochrome P4502C8 inhibitors, cannabis / THC based
 medication, opioid analgesics or antiviral / antibacterial / antifungal agents during
 the last 4 weeks before the screening

 anticonvulsants, antimuscarinics, benzodiazepines, skeletal muscle relaxants,
 non-steroid anti-inflammatory drugs, non opioid analgesics, homeopathic medication and
 herbal therapies during the last 4 weeks before the screening. Subjects should
 continue these medications at that same stable dose throughout the study

 -  Clinically relevant abnormal urine or blood safety laboratory values or active hepatic
 and/or biliary disease (AST or ALT should not be >2 times the upper limit of normal,
 total bilirubin should not be >1.5 times the upper limit of normal)

 -  Participated in any clinical study or has been treated with any investigational drug
 or device within 84 days or the period stipulated by local regulations, whichever is
 longer, prior to the screening
