Brief Summary:
The purpose of this study is to assess the safety and tolerability of two doses of LP08 compared to placebo. Hypothesis: Safety of the LP-08 therapy will not be significantly different from the placebo group. Secondary Efficacy Endpoints: A matched-pair data analysis design will be employed, i.e. the measured outcomes will be subjects' improvements in quantitative and qualitative measures of the disease condition being assessed prior to and after LP-08 instillations at four and eight weeks follow-up visits

Condition or disease Intervention/treatment Phase
Interstitial Cystitis Drug: LP-08 80mg Drug: Normal saline Drug: LP-08 20mg Phase 2

Detailed Description:
This is a single-center, dose-ranging, placebo-controlled, double-blind, randomized study including male and female subjects with interstitial cystitis/bladder pain syndrome (IC/BPS) as determined by a physician using the current diagnostic criteria for IC/BPS. A total of 36 subjects will be enrolled at up to five (5) study sites in the U.S. Enrollment is expected to be completed within one year of initiating the study. The study is comprised of two parts. The first part of the study is a dose-ranging, randomized, double-blind, placebo-controlled study evaluating the safety, tolerability and efficacy of LP-08 at 20 mg and 80 mg doses as compared with placebo. The second part of the study is an Open Label Extension study of the safety, tolerability and efficacy of LP-08 80 mg. Subjects randomized to the placebo control group must have completed the randomized portion study, including the eight week follow-up period, to be eligible for the Open Label Extension.

    The number/severity of adverse events throughout the study

Secondary Outcome Measures :
  1. Efficacy Voids Per Day (VPD) [ Time Frame: 2, 4, 8, 16, 24 weeks following treatment ]

    Reporting a "moderate" or "marked" improvement on the GRA

  3. Efficacy Symptom [ Time Frame: 2, 4, 8, 16, 24 weeks following treatment ]
    The change in the symptoms and problems of interstitial cystitis from the baseline as measured by the O'Leary-Sant Interstitial Cystitis Symptom Index

  4. Efficacy Visual Analog Scale (VAS) [ Time Frame: 2, 4, 8, 16, 24 weeks following treatment ]
    The change in pain as recorded on the VAS

  5. Efficacy Diary [ Time Frame: 2, 4, 8, 16, 24 weeks following treatment ]
    The change from baseline in average voided volume, urgency and nocturia episodes per day as measured on a 3 day voiding diary

Ages Eligible for Study:   18 Years to 70 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

A patient is deemed suitable for inclusion in the study if the patient meets the following criteria:

  1. Male or female at least 18 years of age
  2. IC/BPS diagnosed by a health care provider based the following criteria:

    Complaint of suprapubic pain related to bladder filling, accompanied by other symptoms such as increased daytime and night time frequency, in the absence of proven urinary infection or other obvious pathology Have had IC/BPS symptoms for at least six months Score of ≥ 12 on the ICSI/PI at baseline Urinary frequency > 10 times a day by self-report and confirmed on baseline three-day voiding diary Have IC/BPS that in the judgment of the investigator has been stable in the previous 30 days IC/BPS-related pain defined as a score of > 3 cm and < 9 cm on the pain VAS where 0 is no pain and 10 is maximum pain

  3. Have had inadequate clinical responses with conservative treatments, which may include one or more of the following: 1) timed voiding and behavioral modification therapy, 2) dietary restrictions, 3) stress reduction and/or 5) oral therapy with any of the following medications:

    Antidepressants Antihistamines Antimuscarinic and anticholinergic agents Alpha adrenergic blockers Analgesics Pentosan polysulfate

  4. Women of childbearing potential: have a negative urine pregnancy test at screening, and must agree to use an acceptable from of contraception (oral contraceptives, intrauterine or double barrier methods), as agreed to by the investigator, during the study period
