Nivolumab Plus Chemoradiotherapy in Patients With Muscle-invasive Bladder Cancer (MIBC) Not Undergoing Cystectomy
- Conditions
- Bladder Cancer
- Interventions
- Biological: NivolumabOther: chemoradiotherapy
- Registration Number
- NCT03993249
- Lead Sponsor
- Hellenic GenitoUrinary Cancer Group
- Brief Summary
The purpose of this study is to investigate the effect synchronous use of nivolumab in addition to chemoradiotherapy in patients withnon-metastatic MIBC who are not candidates for radical cystectomy
- Detailed Description
The initial hypothesis is that addition of nivolumab will increase 2-year locoregional control rate from 55% (control arm) to 75% (immunotherapy arm)
There is a 24 month accrual period during which 78 patients will be randomized in a control group (standard chemo-radiotherapy) and the treatment group (chemo-radiotherapy + Nivolumab)
The primary objective would be to compare locoregional control rate at 2-years between patients with MIBC receiving or not receiving nivolumab in addition to chemoradiotherapy.
The secondary objectives are
1. To study the safety of the addition of nivolumab to chemoradiotherapy in patients with MIBC
2. To compare 2-year bladder cancer failure-free (BCFF) rates, defined as distant metastasis free survival (MFS) AND/OR locoregional failure (defined as in primary objective)
3. To compare median overall survival (OS) in patients with MIBC receiving or not receiving nivolumab in addition to chemoradiotherapy
4. Assess the effect of combined treatment on the quality of life
Correlative studies of outcomes with PD-L1expression and with lymphocytic populations in the environment of the tumor

- Primary Outcome Measures
Name Time Method Locoregional control rate 2 years To compare locoregional control rate at 2-years between patients with MIBC receiving or not receiving nivolumab in addition to chemoradiotherapy
- Secondary Outcome Measures
Name Time Method Bladder cancer failure-free (BCFF) rates 2 years To compare 2-year bladder cancer failure-free (BCFF) rates, defined as distant metastasis free survival (MFS) AND/OR locoregional failure (defined as in primary objective)
Assessment of the effect of the combined treatment on the quality of life 2 years Quality of life score assessed by Quality of Life of Cancer Patients Questionnaire (EORTC QLQ-C30). Discomfort measured in a scale from 1 (not at all) to 4 (very much) Overall health and quality of life score measured in a scale from 1 (very poor) to 7 (excellent)
Incidence Rate of treatment-related adverse event (safety and tolerability) 2 years Incidence of adverse events as assessed by CTCAE. After radiotherapy completion, AEs will be assessed according to RTOG/EORTC Late Radiation Morbidity Scoring Schema
Median overall survival (OS) 2 years To compare median overall survival (OS) in patients with MIBC receiving or not receiving nivolumab in addition to chemoradiotherapy
