Primary Outcome Measures:
  • Number of Responders Defined as Having at Least a 30% Reduction in the O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) From Baseline to Study Endpoint [ Time Frame: Baseline to Week 24 ] [ Designated as safety issue: No ]
    The ICSI is a four-item self-administered instrument developed for the evaluation and management of patients with interstitial cystitis. The index measures the presence and extent of symptoms including urinary urgency, urinary frequency, nocturia and pain/burning in the bladder. Each question in the ICSI is on a 0-5 scale, where each answer is given a specific rating. The sum of the individual question ratings is the score for the ICSI. The range of the test is a score of 0 to 20. A lower score indicates a better condition.


Secondary Outcome Measures:
  • Number of Responders Defined as Having at Least a Four Point Reduction in the O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) From Baseline to Study Endpoint [ Time Frame: Baseline to Week 24 ] [ Designated as safety issue: No ]
    The ICSI is a four-item self-administered instrument developed for the evaluation and management of patients with interstitial cystitis. The index measures the presence and extent of symptoms including urinary urgency, urinary frequency, nocturia and pain/burning in the bladder. Each question in the ICSI is on a 0-5 scale, where each answer is given a specific rating. The sum of the individual question ratings is the score for the ICSI. The range of the test is a score of 0 to 20. A lower score indicates a better condition.

Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Pentosan polysulfate sodium 100 mg once a day
One 100 mg pentosan polysulfate sodium capsule in the morning and 1 matching placebo capsule in the afternoon and evening for 24 weeks
Drug: Pentosan polysulfate sodium 100 mg
One 100 mg pentosan polysulfate sodium capsule in the morning, and 1 matching placebo capsule in the afternoon and evening for 24 weeks
Experimental: Pentosan polysulfate sodium 100 mg three times a day
One 100 mg pentosan polysulfate sodium capsule 3 times a day (morning afternoon and evening) for 24 weeks
Drug: Pentosan polysulfate sodium 100 mg
One 100 mg pentosan polysulfate sodium capsule 3 times a day (morning, afternoon, and evening) for 24 weeks
Placebo Comparator: Placebo
Placebo One placebo capsule 3 times a day (morning afternoon and evening) for 24 weeks
Drug: Placebo
One placebo capsule 3 times a day (morning, afternoon and evening) for 24 weeks

Detailed Description:

The purpose of this multi-center, double-blind (neither the patient nor the physician knows whether drug or placebo is being taken, or at what dosage), randomized (patients are assigned different treatments based on chance), parallel group trial is to evaluate the effectiveness and safety of two doses of pentosan polysulfate sodium (100 mg once a day and 100 mg three times a day) versus placebo for 24 weeks for the relief of bladder pain or discomfort associated with interstitial cystitis. The hypothesis of the study is that there is no treatment difference in the proportion of responders at study endpoint (Week 24). Effectiveness will be assessed based on the reduction in the O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) total score. Safety assessments include vital signs, laboratory tests, adverse events and physical exams. Patients will receive one of the following study treatments by mouth each day for 24 weeks: pentosan polysulfate sodium 100 mg once a day group - one pentosan polysulfate sodium 100 mg capsule in the morning, and one matching placebo capsule in the afternoon and evening; pentosan polysulfate sodium 100 mg capsule three times a day group - one pentosan polysulfate sodium 100 mg capsule in the morning, afternoon and evening; placebo group - one placebo capsule in the morning, afternoon and evening
