Clinical Trial Summary

Common local side effects are generally seen during induction and during the first 6 months of BCG maintenance. BCG-related cystitis is frequent and unavoidable. Furthermore, repeated BCG instillation increases the incidence and severity of irritative bladder symptoms. Several methods attempted to reduce the intensity and frequency of BCG- related lower urinary tract symptoms (LUTS), such as, administration of anti-tuberculosis drug isoniazid or oral antibiotic ofloxacin or by reducing the BCG dose, but without any encouraging results. Local side effects requiring cessation of treatment are seen more frequently in the first year of therapy, preventing patients from receiving their BCG maintenance regimen. Pentosan Polysulphate (PPS), is an oral medication with unique analgesic properties used to relieve bladder pain and discomfort related to other conditions, has been investigated in a small study with encouraging result in this patient population. This suggest that PPS is well tolerated and effective at decreasing BCG-related LUTS. The purpose of this study is first to investigate the efficacy of co-administration of Pentosan Polysulphate to prevent these adverse events and the impact of this intervention on quality of life. The second goal is to determine which patients are more vulnerable to develop BCG- related lower urinary tract symptoms (LUTS), based on clinical assessment, demographics data, voiding parameters, and urinary inflammatory markers, and then to assess the effectiveness of BCG therapy following co-administration of ELMIRON.

Description:

Study purpose and rationale: BCG-related LUTS is a condition which can have a significant negative impact on the psychological well-being, social functioning, and overall quality of life of bladder cancer patients. Clinical studies have demonstrated effects of PPS on damaged urothelium in the bladder, which is a key feature for diminishing BCG local side effects. The "dual action" protective effect on bladder epithelium and replacing the mucus in the glycosaminoglycan layer of damaged urothelium provides a scientific rationale to evaluate whether PPS treatment may be a preventive option for NMIBC patients treated with BCG. It is therefore important to find a treatment strategy to control the BCG-related LUTS so that candidate patients do not lose the benefit of BCG treatment while maintaining its efficacy and ensuring optimal outcomes. This study will identify the patients that are more vulnerable to develop these side effects and determine the efficacy of PPS to diminish BCG- related lower urinary tract symptoms (LUTS) and associated impact on quality of life. Sample Size: For the first aim, power analysis was estimated using a One-way (ANOVA) hypothesis test with a type 1 error of 5%, 80% power, and 20% dropout rate. It was calculated based on the ICIQ-LUTSqol expected values. The baseline mean ICIQ-LUTSqol score used was 33.1 and SD of 7.3, the outcome ICIQ-LUTSqol score mean used 28.48, with a SD of 4.95, which is the minimally important difference of 3.7124. The investigator calculate a number of 30 patients per group, for a total sample size of 60. (Calculated by pass program v 15.0.03) For the second aim, a total number of 40 candidates will be recruited for this prospective study. The investigator expect a minimum of 30% of patients to experience BCG related LUTS, therefore 18 patients with LUTS The SD of ICIQ-LUTSqol is 7.3 and its maximum score is 76. Therefore, the investigator estimate a required sample size of 14 (1.96 2 SD 2 / 3.82), for a p value < 0.05, and an absolute error of 0.05. The comparison between groups of the cohort will be conducted using chi-square analysis. A 2-sample t test will be used to compare baseline scores between study groups. The Wilcoxon rank-sum test will be used to calculate whether the mean difference of all the outcome measures between groups. A p value <0.05 considered statistically significant. Approximately 100 subjects are expected to be enrolled for this prospective trial. It is expected that 20% of subjects will not qualify for randomization after screening. The study is expected to randomize approximately 80 subjects into the double-blind treatment where subjects will be allocated to ELMIRON 100 mg, or matched placebo TID in a 1:1 ratio. A post randomisation dropout rate of 20% has been estimated, resulting in 60 evaluable subjects. This provides an 80% power for the primary endpoint. Study design and description This is a Phase 2, double-blind, randomized, placebo-controlled, parallel-group study in patients 18 to 85 years old with NMIBC. The study will include a two weeks Screening Period; and a 6-week double-blind Treatment Period. Participants will return to the clinic for a safety Follow-up Visit 6 and 18 weeks after treatment is completed for a total study duration of 24 weeks. All participants will enter the Screening Period during which eligibility will be assessed, where subjects must have at least 3 days of daily diary symptom collection. Participants who continue to meet eligibility criteria, including collection of diary data, Negative Urine analysis and culture, and bladder scan showing PVR less than 150ml at the end of the Screening Period will enter the Treatment Period. Participants will be randomly assigned (1:1) to receive study drug (ELMIRON 100 mg, or placebo) TID for a duration of 6weeks. Efficacy will be assessed by number of urgency episodes per 24 hours based on a 3-day bladder diary, the Overactive Bladder-Validated 8- Question (OAB-V8), the visual analogue scale for suprapubic and perineal pain (VAS), the ICIQ-Lower Urinary Tract Symptoms Quality of Life Questionnaire (ICIQ-LUTSqol), and quantitative measures of urinary inflammatory markers levels (TRAIL, IFN, IL-2, IL-10). Safety assessments will be conducted throughout the trial and will include physical examinations, vital signs, clinical laboratory evaluations, cystoscopy, urine cytology, and adverse events (AEs). Study conduct: AIM 1: Determine the effectiveness of co-administration of Pentosan Polysulphate in preventing BCG-related LUTS. Rationale: The investigator aim to compare the effect of PPS (ELMIRON) to placebo on the incidence and severity of local adverse effects of BCG intravesical therapy and its impact on health-related quality of life (HRQoL) in patients with superficial bladder cancer. As the currently used symptomatic treatment drugs failed to prove optimal efficacy, new treatment options are warranted. PPS could be a promising drug especially when considering its effectiveness in controlling LUTS related to similar pathologies. The first aim will be a prospective, randomized, double-blinded, placebo-controlled pilot study, A total of 60 subjects will be assessed and included in the study after obtaining their consent and fulfilling the inclusion criteria. Within 14 days after TURBT, patients will undergo baseline evaluation and will be randomized into two groups as the following: - Group A will receive PPS 100 mg (ELMIRON) thrice daily PO. (30 subjects) - Group B will receive placebo thrice daily PO. (30 subjects) Treatment period for all groups will be 6 weeks as co-administration with BCG instillation. AIM 2: Identify predisposing factors to developing BCG-related LUTS based on clinical, demographic and voiding parameters The second aim will involve an in-depth pre-treatment analysis of clinical parameters of patients planned for BCG instillation and correlation with the development of BCG local side effects. Prior to receiving BCG induction, patients will be evaluated for baseline demographics, voiding diary, non-invasive uroflowmetry with post-void residual, LUTS and quality of life questionnaires (OAB-V8, ICIQ-LUTSqol, and VAS). Objective outcomes assessment using quantitative measures of TRAIL, IFN, IL-2, and IL-10 levels in the urine before and following BCG induction treatment will be quantitated using a sandwich ELISA and correlated with the severity of LUTS. This prospective cohort will be followed 3 months after completing the induction phase by repeating the clinical assessment described and identify their oncological response to the treatment by urine cytology/cystoscopy. Confidentiality: All study outcomes and documents will be considered as confidential. The Investigator and members of his/her research team must not disclose such information without prior written authorization. The anonymity of participating patients must be maintained. Subjects will be identified on CRFs and other documents by their subject number/code, not by name. Documents that identify the subject (eg, the signed informed consent) must be retained in confidence by the Investigator. All data will remain confidential and will be available for access by the investigators only. A unique identifier to keep their identity confidential will identify the participant. The information will be kept for duration of 10 years. Statement on ethical consideration: The proposed study protocol ensures that the Sponsor and Investigator adhere to the principles of the GCP guidelines of the ICH, and of the recent version of the Declaration of Helsinki. The study also will be following with local ethics requirements.
