Average Number of Doses Per Day of Rescue Medication Used

In case of inadequate pain relief or worsening symptoms of interstitial cystitis, any US FDA approved commercial product of acetaminophen 500 mg tablet/capsule could be taken as rescue medication. Results were normalized by doses of rescue medication used relative to the total number of days participant was in the study.

Time frame: Baseline up to Week 16

Population: rFAS population: All randomized participants who received at least 1 dose of treatment, completed at least 5 diary days during 7 days prior to randomization, had at least 1 diary day post-randomization, and who provided baseline and post-randomization primary efficacy data for 4 or more days within the predefined diary windows.

Change From Baseline in Mean Interstitial Cystitis Pain Severity Per Urinary Event at Week 2, 4, 6, 10 and 16

Mean interstitial cystitis pain severity per urinary event (toilet void, accidental urine loss, urgency episode) was calculated as the mean of all pain severities recorded during the diary period when these events were measured. For each urinary event (toilet void, accidental urine loss, urgency episode), participants marked their associated level of pain intensity (or pressure, aching, burning, discomfort) using an 11-point NRS ranging from 0 denoting none (no pain), and 10 denoting worst (pain as bad as you can imagine), where higher scores indicated higher pain. Total mean interstitial cystitis pain severity per urinary event score ranged from 0 (no pain) to 10 worst (pain as bad as you can imagine), where higher scores indicated more pain.

Change From Baseline in Pelvic Pain and Urgency/Frequency (PUF) Total Score at Week 2, 4, 6, 10 and 16

The pelvic pain and urgency/frequency (PUF) was a 12-item questionnaire used to measure the severity of symptoms and the degree to which participants were bothered. Symptom questions include 3, 4, or 5 ranked answers, with higher answers indicating more voids, or greater frequency of pain. The bother questions consisted of 4 ranked answers from 0-never to 3-always with higher answers indicating more bothering. Total score was calculated as the sum of symptom score and bother score and ranged from 0 (no symptoms/bother) to 35 (higher symptom severity/bother), where a higher score indicated greater symptom severity and higher bother from pelvic pain and frequency.

Percent Change From Baseline in Mean Interstitial Cystitis Pain Severity Per Urinary Event at Week 2, 4, 6, 10 and 16

Mean interstitial cystitis pain severity per urinary event (toilet void, accidental urine loss, urgency episode) was calculated as the mean of all pain severities recorded during the diary period when these events were measured. For each urinary event (toilet void, accidental urine loss, urgency episode), participants marked their associated level of pain intensity (or pressure, aching, burning, discomfort) using an 11-point NRS ranging from 0 denoting none (no pain), and 10 denoting worst (pain as bad as you can imagine), where higher scores indicated higher pain. Total mean interstitial cystitis pain severity per urinary event score ranged from 0 (no pain) to 10 worst (pain as bad as you can imagine), where higher scores indicated more pain.

Percent Change From Baseline in Pelvic Pain and Urgency/Frequency (PUF) Symptom Total Score at Week 2, 4, 6, 10 and 16

The pelvic pain and urgency/frequency (PUF) was a 12-item questionnaire used to measure the severity of symptoms and the degree to which participants were bothered. Symptom questions include 3, 4, or 5 ranked answers, with higher answers indicating more voids, or greater frequency of pain. The bother questions each of 4 ranked answers from 0-never, to 3-always with higher answers indicating more bothering. Total score was calculated as the sum of symptom score and bother score and ranged from 0 (no symptoms/bother) to 35 (higher symptom severity/bother), where a higher score indicated greater symptom severity and higher bother from pelvic pain and frequency.
