Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: •To assess the antitumor activity measured as pT0N0 rate, defined as no evidence of residual disease based on pathological review of the surgical specimen •To assess the percentage of pathological downstaging response ;Secondary Objective: •To evaluate the percentage of tumour downstaging •To estimate the event-free survival (EFS) •To estimate the overall survival (OS). •To evaluate the Objective Response Rate (ORR) after neoadjuvant treatment •To assess the safety profile and tolerability of both schemes •To calculate the rate of delay of surgery. ;Primary end point(s): Primary endpoint(s) •Pathological complete response (pCR). •Pathological downstaging <ypT2. ;Timepoint(s) of evaluation of this end point: After a maximum of 30 weeks from the start of treatment (First Follow- up visit ) on specimens obtained during radical cystectomy. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Secondary endpoints •Rate of pathological downstaging (pDS) •Event-free Survival rate. •OS. •ORR according to RECIST, after neoadjuvant treatment. •Adverse events. •Rate of delay of surgery (classed as a delay event if performed > 6 weeks after last dose of treatment). ;Timepoint(s) of evaluation of this end point: During treatment and follow-up period. | — |
