About this study

Official title: A PHASE 2B, RANDOMIZED, DOUBLE-BLIND, PLACEBO-CONTROLLED, DOSE RANGING STUDY EVALUATING THE EFFICACY AND SAFETY OF TANEZUMAB FOR THE TREATMENT OF MODERATE TO SEVERE PAIN ASSOCIATED WITH INTERSTITIAL CYSTITIS/ PAINFUL BLADDER SYNDROME (IC/PBS).

In a previous study in patients with interstitial cystitis/ painful bladder syndrome (IC/PBS), tanezumab has shown to be efficacious in relieving the pain associated with IC/PBS, as well as some effect on reducing urinary urgency. Only one dose was studied, and tanezumab was well tolerated. In this study, the hypothesis being tested is that tanezumab will show efficacy at several doses on reducing pain with sufficient tolerability. Tanezumab's safety will also be assessed at different dose levels

Read the detailed description

This study was terminated on 16 November 2010 following a US FDA partial clinical hold for the tanezumab interstitial cystitis clinical study announced on 19 July 2010 for potential safety issues, and following a pre-planned interim analysis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Mean Average Daily Pain Score at Week 8

    Average daily pain score was defined as the mean of the last 7 daily diary pain ratings prior to each assessment time point. Participants rated their average bladder pain due to interstitial cystitis/painful bladder syndrome (IC/PBS) over the past 24 hours on an 11-point numeric rating scale (NRS) ranging from 0 = no bladder pain to 10 = worst possible bladder pain.

    Measured: Baseline, Week 8

Secondary outcomes (22)
  1. Change From Baseline in Mean Average Daily Pain Score at Week 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, and 24

    Average daily pain score was defined as the mean of the last 7 daily diary pain ratings prior to each assessment time point. Participants rated their average bladder pain due to interstitial cystitis/painful bladder syndrome (IC/PBS) over the past 24 hours on an 11-point numeric rating scale (NRS) ranging from 0 = no bladder pain to 10 = worst possible bladder pain.

    Measured: Baseline, Week 1, 2, 3, 4, 5, 6, 7, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24

  2. Percentage of Participants Who Achieved At Least 30 Percent (%) and 50% Reduction in Mean Average Daily Pain Score

    Average daily pain score was defined as the mean of the last 7 daily diary pain ratings prior to each assessment time point. Participants rated their average bladder pain due to interstitial cystitis/painful bladder syndrome (IC/PBS) over the past 24 hours on an 11-point numeric rating scale (NRS) ranging from 0 = no bladder pain to 10 = worst possible bladder pain.

    Measured: Week 8, 16

  3. Change From Baseline in Mean Worst Daily Pain Score at Week 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23 and 24

    Worst daily pain score was defined as the mean of the last 7 daily diary pain ratings prior to each assessment time point. Participants rated their worst bladder pain due to IC/PBS over the past 24 hours on an 11-point NRS ranging from 0 = no bladder pain to 10 = worst possible bladder pain.

    Measured: Baseline, Week 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24

  4. Patient Global Assessment of Health Status Scores

    Participants answered: "Considering all the ways your bladder condition (IC/PBS) affects you, how are you doing today?" Participants responded on a 5-point scale where 1 = very good and 5 = very poor.

    Measured: Baseline, Week 2, 8, 16, 24

  5. Number of Participants With Global Response Assessment Scores

    Participants were asked: "compared to when you began this trial, how would you rate your IC/PBS symptoms now?" Participants responded by using a 7-point symmetric scale where 1 = markedly worse, 2 = moderately worse, 3 = slightly worse, 4 = no change, 5 = slightly improved, 6 = moderately improved, and 7 = markedly improved.

    Measured: Week 8, 16, 24

  6. Number of Micturitions Per 24 Hours

    The micturition frequency per 24 hours was calculated from the sum of voids divided by the diary period over which they were collected.

    Measured: Baseline, Week 4, 8, 12, 16, 20, 24

  7. Number of Nocturnal Micturitions Per 24 Hours

    The nocturnal frequency per 24 hours was defined as the number of voids after going to bed and before getting up (the times of going to bed and getting up were recorded in the diary). The nocturnal micturition per 24 hours was calculated as the sum of voluntary voids that occurred during a night's sleep, divided by the number of nights over which this was collected.

    Measured: Baseline, Week 4, 8, 12, 16, 20, 24

  8. Number of Micturition-related Urgency Episodes Per 24 Hours

    The micturition urgency frequency per 24 hours was calculated as the sum of urgency episodes (when participant had to rush to get to the bathroom to urinate) occurring during the diary period when this was measured, divided by the number of days over which they were recorded.

    Measured: Baseline, Week 4, 8, 12, 16, 20, 24

  9. Participant's Urge to Urinate

    Participants completed 7-item questionnaire assessing their urge to urinate over the past 24 hours. The items were assessed on a 5-point response scale ranging from 0 (never) to 4 (always). Urge to urinate was calculated as the total of the 7 'urge' items with a minimum total score of 0 and a maximum total score of 28. Higher scores indicated greater symptom severity. An average was determined from the 3 days recorded in the 7-day diary period prior to each assessment time point.

    Measured: Baseline, Week 4, 8, 12, 16, 20, 24

  10. Mean Voided Volume Per Micturition

    Mean volume voided per micturition was calculated as the total urine volume voided during the diary period when this was measured over 1 day, divided by the number of voids (with non missing volumes) during that day.

    Measured: Baseline, Week 4, 8, 12, 16, 20, 24

  11. O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) Score

    The ICSI contained 4 questions that measured symptom severity including urinary urgency, urinary frequency, nocturia and pain/burning in the bladder. Each question in the ICSI was rated on a 0-5 scale. The sum of the individual question ratings was the total score for the ICSI. Total scores ranged from 0 to 20, with higher scores indicating greater symptom severity and bother.

    Measured: Baseline, Week 2, 8, 16, 24

  12. Brief Pain Inventory-Short Form (BPI-sf) Score

    BPI-sf is a 7-item self-administered questionnaire to assess the pain severity and pain interference on daily functions. Pain Severity Index (PSI) is an average of Questions 2-5 which measured the severity of pain (worst, least, average, right now) over past 24-hours on an 11-point scale (0=no pain to 10=pain as bad as you can imagine). Pain Interference Index (PII) is an average of 7 pain interference items of Question 7 that measured the level of interference of pain on daily function (general activity, mood, walking ability, normal work, relations with other people, sleep, enjoyment of life) on an 11-point scale (0=did not interfere to 10=completely interfered). Pain Severity Index and Pain Interference Index total scores ranged from 0 to 10, where higher scores indicate greater pain or greater interference.

    Measured: Baseline, Week 8, 16, 24

  13. Number of Participants With Patient Global Satisfaction Assessment Scores

    Participant global satisfaction is assessed using Patient Reported Treatment Impact (PRTI) which is a self-administered questionnaire containing 4 items to assess participant satisfaction, previous treatment, preference and willingness to continue using the study medication. Participants were asked: "Overall, how satisfied are you with the drug that you received since you entered this trial?" Participant's response is rated on a 5-point scale where 1=extremely dissatisfied (dissatisf), 2=dissatisfied, 3=neither satisfied nor dissatisfied (satisfy/dissatisfy), 4=satisfied and 5=extremely satisfied. Number of participants with each response is reported.

    Measured: Week 8, 16, 24

  14. Number of Participants With Patient Global Preference Assessment Score

    Participant global preference is assessed using PRTI which is self-administered questionnaire containing 4 items to assess participant satisfaction, previous treatment (T/T), preference and willingness to continue using study medication. Participant reported previous T/T under following categories: lifestyle interventions, physical therapies, toileting programs, drug given into bladder, drug taken by mouth, surgery, and no T/T. Participant preference was assessed on a 5-point scale where, 1=No, I definitely prefer my prior T/T (Def Pref Prior), 2=I have a slight preference for my prior T/T (Slight Pref Prior T/T), 3=I have no preference either way (No preference), 4=I have a slight preference for the drug that I am receiving now (Slight Pref Current), 5=Yes, I definitely prefer the drug that I am receiving (Def Pref Current Drug) now. Number of participants under each of the categories is reported. For previous T/T, a single participant may be represented in more than 1 category.

    Measured: Week 8, 16, 24

  15. Number of Participants With Willingness to Re-use Medicine Assessment

    Participant willingness to re-use study medication is assessed using PRTI which is a self-administered questionnaire containing four items to assess participant satisfaction, previous treatment, preference and willingness to continue using the study medication. Participants were asked: "In the future, would you be willing to use the same drug that you have received since you entered this trial for your chronic prostatitis?" Participants responded on 5-point scale where, 1=No, I definitely would not want to use the same drug again (definitely not want), 2=I might not want to use the same drug again (might not want), 3=I am not sure (not sure), 4=I might want to use the same drug again (might want), 5=Yes, I would definitely want to use the same drug again (definitely want).

    Measured: Week 8, 16, 24

  16. Euro Quality of Life (EQ-5D) - Health State Profile Utility Score

    EQ-5D is a participant rated questionnaire to assess health-related quality of life in terms of a single utility score. Health State Profile component assesses level of current health for 5 domains: mobility, self-care, usual activities, pain and discomfort, and anxiety and depression; 1 indicates better health state (no problems); 3 indicates worst health state ("confined to bed"). Scoring formula developed by EuroQol Group assigns a utility value for each domain in the profile. Score is transformed and results in a total score range -0.594 to 1.000; higher score indicates a better health state.

    Measured: Baseline, Week 8, 16, 24

  17. Painful Bladder/Interstitial Cystitis Quality of Life Questionnaire (PBIC-QoL) Total Score

    PBIC-QoL: 25-item questionnaire to assess impact of IC/PBS on health related quality of life over past 7 days. PBIC-QoL included 17 items (Items 2, 5, 8, 11, 14, 18, 20 and 21 did not form part of final instrument), of which 13 were divided into 3 dimensions: activity limitations (Items 1, 3, 4, 6, 7), impact on emotional wellbeing (Items 13, 15, 16, 17, 19), impact on sleep (Items 22, 23, 24). Four items: Item 9 (impact on going out with friends), Item 10 (impact on concentration), Item 12 (impact on eating and drinking), Item 25 (impact on sex life) were scored separately to dimension scores as single items. Items were scored from 4 'not at all' to 0 'extremely difficult' or 'a very great deal'. Eight items included a 'not applicable' response option. Dimension scores ranged from 0 to 4, higher score indicate better quality of life. Total score=sum of the dimension and single item scores, ranged from 0 to 28, higher score indicated better quality of life.

    Measured: Baseline, Week 2, 8, 16, 24

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change From Baseline in Mean Average Daily Pain Score at Week 8 (time frame: Baseline, Week 8). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00999518, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2021.
