Safety, Tolerability and Efficacy Study of LiRIS® 400 mg in Women With Interstitial Cystitis

Participants rated their bladder pain over the previous 24 hours in an electronic diary using a horizontal line NRS by putting a mark on the line where: 0 (the far left of the line)=no pain to 10 (far right of the line)=worst pain imaginable. Bladder pain was averaged over a period of 3 days. A negative change from Baseline indicates improvement.

Participants recorded number of daily voids (day-time and night-time daily voids) in a 3 day Voiding Frequency electronic diary. The total number of daily voids was averaged over a period of 3 full days. A negative change from Baseline indicates improvement.

Participants recorded number of night-time daily voids in a 3 day Voiding Frequency electronic diary. The total number of night-time daily voids was averaged over a period of 3 days. A negative change from Baseline indicates improvement.

Participants recorded the amount of each void in millimeters (mL) in an electronic diary. The total amount of void per micturition (each void) was averaged over a period of 24 days. A negative change from Baseline indicates improvement.

Participants rated their bladder pain immediately completing voiding in an electronic diary using a horizontal line NRS by putting a mark on the line where: 0 (the far left of the line)=no pain to 10 (far right of the line)=worst pain imaginable. The average of the data from the first 5 voids prior to Baseline and the 3 days prior to Day 12 were averaged for analyses. A negative change from Baseline indicates improvement.

The ICSI is a participant reported questionnaire to rate their symptoms by answering 4 questions. Question (Q) 1 and 2 (urine urgency) using a 6-point scale where: 0=Not at All to 5=Almost Always. Q3 (night-time voids) using a 6-point scale where: 0=None to 5=5 or More Times. Q4 (pain and burning) using a 6-point scale where: 0=Not at All to 5=Usually. The total score is the sum of the individual scores for a total possible score of 0 (best) to 20 (worst). A negative change from Baseline indicates improvement.

The ICPI is a participant reported questionnaire to rate their problems in the following 4 areas: Frequent urination; Getting up at Night to Urinate: Urination with little warning; Burning pain and discomfort. Questions are answered on a 5-point scale where: 0=No Problem to 4=Big Problem. The total score is the sum of the individual scores for a total possible score of 0 (best) to 20 (worst). A negative change from Baseline indicates improvement.

The BPIC-SS is a participant reported questionnaire consisting of 8 items. Questions (Q) 1-5 (How often urination because of pain; Need to urinate after just urinating; How often urination to avoid worse pain; How often feeling of pressure in bladder; How often pain in bladder) answered on a 5-point scale where: 0=Never to 4=Always. Q 6-7 (Bothered by frequent Day-time urination; Bothered by Night-time urination) answered on a 5-point scale where: 0=Not At All to 4=A Great Deal. Q8 (pain) rated on a NRS by putting a mark on the line where: 0 (the far left of the line)=no pain to 10 (far right of the line)=worst pain imaginable. The Total Score is the sum of the individual questionnaire of all 8 items for a total possible score of 0 (best) to 38 (worst). A negative change indicates improvement.

The BPI is a 7-item participant completed questionnaire. The participant answered questions as to how pain interfered with: General Activity, Mood, Walking Ability, Normal work, Relations with other people, Sleep and Enjoyment of life. Questions were answered on an 11-point scale where: 0=Does not interfere to 10=Completely interferes. The total score is the average of the individual questionnaire items for a total possible score of 0 (best) to 10 (worst). A negative change from Baseline indicates improvement.
