Primary | Assessment of Objective Response Rate (ORR) as per CTCAE v5.0. | Objective Response Rate (ORR) The proportion of patients with CR/PR.The ORR will be determined as below.Complete response(CR):resolution of hematuria (gross/macroscopic hematuria for grade II/III and microscopic hematuria for grade I hemorrhagic cystitis) Partial response(PR):improvement (decrease by at least 1 grade of hemorrhagic cystitis but not complete resolution of hematuria over 3 months from the start of treatment.The grading of hemorrhagic cystitis will be as per the CTCAE v5.0. | Baseline | |

Secondary | Assessment of Bladder Cancer Index (BCI) scores. | Bladder cancer index (BCI) scores will be calculated at baseline, 1 month and 3 months for each study participant.
Minimum value - 0, Maximum value - 100, Higher scores depict better outcome. |
Baseline, post 1 month, post 3 months | |
Secondary | Assessment of Treatment Failure (TF). | Treatment Failure (TF) defined as requirement of alternative intervention for persistent severe hematuria within 3 months from the start of treatment or early stoppage due to intolerable side effects in the absence of PR/CR [Intervention: multiple cystoscopies with clot evacuation, cystectomy, hyperbaric oxygen therapy (HBOT) or transfusion due to persistent drop in hemoglobin]. | Post 3 months | |
Secondary | Evaluation of treatment failure-free survival. | Treatment failure-free survival is defined as the time from enrolment to the date of first intervention up to 3 months or date of discontinuation of therapy due to intolerable side effects in the absence of PR/CR. | Baseline to up to 3 months | |
Secondary | Assessment of Quality of Life (QOL) using EORTC -QLQ C-30 questionnaire. | QoL will be measured using the EORTC-QLQ-30 questionnaire at baseline, 1 month and 3 months for each study participant.
Minimum value - 0, Maximum value cannot be predetermined. five functional scales (physical, role, cognitive, emotional, and social), three symptom scales (fatigue, pain, and nausea and vomiting), a global health status / QoL scale, and a number of single items assessing additional symptoms commonly reported by cancer patients (dyspnoea, loss of appetite, insomnia, constipation and diarrhoea) and perceived financial impact of the disease. Therefore, higher scores depict better outcomes for some scales whereas for some scales lower scores depict better outcomes. |
