Brief Summary:

To evaluate the safety and efficacy of 8 weeks of treatment with MN-001 at 500 mg bid, 500 mg once daily vs. placebo in patients with Interstitial Cystitis.

Condition or disease	Intervention/treatment	Phase
Interstitial Cystitis	Drug: MN-001 BID; Drug: MN-001; Drug: Placebo	Phase 2

Detailed Description:

This is a randomized, double-blind, placebo-controlled, multi-center study to evaluate the efficacy and safety of two dosing regimens of MN-001 in patients with Interstitial Cystitis (IC). Patients will be screened for study eligibility within seven to nine days of randomization. Eligible patients will be randomized in a 1:1:1 ratio to receive either 500 mg MN-001 bid, 500 mg MN-001 once daily or placebo. Patients will be dispensed study drug beginning at Baseline (Visit 2) and will return to the study center for Visit 3 (28 days ± 2 days after Baseline), and Visit 4 (56 days ± 2 days after Baseline), at end of study for safety and efficacy assessments. The patient will be contacted by telephone at Week 6 (42 days ± 2 days after Baseline) for an interim follow up. Study drug will be dispensed at Visits 2 and 3. Safety assessments will include adverse events, physical examinations, clinical laboratory testing, and changes in vital signs. Efficacy assessments include percentage of patients at least "moderately improved" for each treatment group using the patient reported Global Response Assessment (GRA) (see Appendix 1). Secondary assessments include a decrease in bladder pain/urgency based on change in the patient rating from baseline to endpoint using the GRA (see Appendix 1), modified Pelvic Pain and Urgency/Frequency (PUF) Patient Symptom Scale (see Appendix 2) and the O'Leary Sant IC Symptom and Problem Index.

Outcome Measures

Primary Outcome Measures :

1. Number Subjects at Least "Moderately Improved" for Each Treatment Group in Patient Reported Global Response Assessment (GRA) [ Time Frame: 8 weeks ]
   The primary endpoint was the GRA overall change "in their condition" at Week 8. Each patient completed the questionnaire that rated the improvement in their IC symptoms based on responses to the GRA questions. Each question asked the patient to describe the OVERALL CHANGE in pain, urgency, frequency or overall change in their problem compared to the status before taking the study medication. Each parameter was rated on a 7 point scale: markedly worse, moderately worse, mildly worse, same, mildly improved, moderately improved and markedly improved.

Secondary Outcome Measures :

1. Number of Responders for GRA Assessment in Their Condition at Week 4. [ Time Frame: 4 weeks ]
   Responders were defined as patients who were 'moderately improved' or 'markedly improved' and non-responders were defined as patients who were 'markedly worse', 'moderately worse', 'mildly worse', no change, or 'mildly improved' on the GRA assessments.
