You may qualify if…

• ≥ 18 years of age.
• Have IC that meets disease diagnostic criteria as defined by a history of the following:
• Cystoscopy/hydrodistension with a diagnosis of IC confirmed by findings of Hunner's ulcer or glomerulation
• Symptoms of bladder pain and urinary urgency for at least 6 months
• Urinary frequency while awake at least 8 times a day while awake
• Nocturia at least twice a night
• Symptoms not significantly relieved by antimicrobial agents, anticholinergic drugs, or antispasmodics
• Have IC that in the judgment of the investigator has been stable in the previous 30 days
• Have IC-related pain despite current therapy, defined as a score of 4 or greater [(on a scale from 0 (none) to 9 (severe)] on average over the past month and confirmed by the voiding diary collected at Visit 2
• Have at least one voided volume ≥ 75 cc in a 24 hour period, confirmed by the voiding diary collected at Visit 2
• Patients of childbearing potential must agree to use an acceptable form of contraception (oral contraceptives, intrauterine device or double barrier methods) from Visit 1 through Visit 6
• Provide signed informed consent

You may not qualify if…

• Currently pregnant or breastfeeding
• Presence of ulcers on the pre-treatment cystoscopy
• Intravesical therapy or bladder hydrodistention within the previous 60 days
• Initiation of pentosan polysulfate sodium (Elmiron®) within the previous 16 weeks
• Use of fentanyl patches, morphine sulfate, methadone or B\&O supprettes within the previous 30 days.
• Previous augmentation cystoplasty, cystectomy or cystolysis, neurectomy (i.e., hypogastric nerve plexus ablation) or implanted peripheral nerve stimulator which has affected bladder function
• History of ureteral reflux. Patients with a history of childhood urinary tract infections, recurrent urinary tract infections as an adult (defined as >3 culture documented episodes within the previous 12 months), or pyelonephritis at any time must have a cystourethogram to rule out ureteral reflux.
• Evidence of renal impairment (creatinine > 2 times the upper limit of normal at Visit 1), hepatic impairment (AST or ALT > 3 times the upper limit of normal at Visit 1), clinically significant cardiovascular, respiratory, or psychiatric diseases
• Any condition that in the judgment of the investigator would interfere with the patient's ability to provide informed consent, comply with study instructions, place the patient at increased risk, or which might confound the interpretation of the study results
• Treatment with a drug or medical device that has not received regulatory approval within the previous 30 days
• Investigators, study staff and their immediate families. Immediate family is defined as current spouse, parent, natural or legally adopted child (including a stepchild living in the investigator's household), grandparent, or grandchild.
• Previously completed or withdrawn from this study
• Urinary tract or prostatic infection within the past 3 months before study entry
• Active genital herpes or vaginitis
• Urethral diverticulum
• Uterine, cervical, vaginal, or urethral cancer within the past 5 years before study entry
• History of cyclophosphamide or chemical cystitis, urinary tuberculosis or radiation cystitis
