E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine MPDL3280A's ability to reduce the size of bladder cancer before surgery (measured as pathological complete response rate), and assess the impact of the drug on the body's immune system. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are as follows: - Assess the safety and tolerability of MPDL3280A in this patient population by collecting information about adverse events and surgical complications. - Assess the anti-tumour effect of MPDL3280A by examining the radiological response (looking at pre- and post-treatment MRI/CT scan images) and “disease free survival” rates. - Assess the effect of MPDL3280A on overall patient survival. |

E.5 End points |

Clinical: Pathological complete response rate (pCRR) defined as ≥20% decrease in residual disease of the bladder, based on histological evaluation of the resected bladder specimen collected during cystectomy (post–treatment).
Biological: Dynamic changes in T cell subpopulations (CD8 and/or CD3) measured in tumour samples collected pre- and post-treatment with MPDL3280A. |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Clinical: pCR rate will be based on histological evaluation of the resected bladder specimen collected during cystectomy (after 1-2 cycles of MPDL3280A treatment).
Biological: The change in T cell expression will be measured in tumour biopsy samples collected before and after treatment with MPDL3280A (an archival sample and a sample taken at cystectomy or post- treatment biopsy). |
|
E.5.2 | Secondary end point(s) |
• Incidence, nature and severity of adverse events graded according to NCI-CTCAE v4.03 collected during and after MPDL3280A treatment. • Surgical complications as assessed by the Clavien-Dindo scoring system. • Radiological response, defined as a >30% decrease in tumour diameter from the baseline scan based on local investigator assessments • Disease-free survival, defined as time between the date of enrolment to first evidence of disease progression based on local investigator assessments or death, whichever occurs first. • Overall survival, defined as the time between the date of enrolment and death due to any cause. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
• Adverse events will be recorded during treatment and up to 24 weeks post cystectomy (AEs are recorded up to 4 weeks post-cystectomy, and unresolved AEs monitored until resolved or until 24 weeks post-cystectomy). Surgical complications will be assessed by the Clavien-Dindo scoring system post-cystectomy. • Radiological response will be assessed before and after treatment with MPDL3280A (baseline and pre-cystectomy). • Disease free survival will be recorded from enrolment until first evidence of disease recurrence or death; patients are followed up for 2 years after cystectomy. • Overall survival is defined as time from enrolment to death due to any cause.
