Abstract 652O


The optimal perioperative chemotherapy regimen for patients (pts) with MIBC is not defined.


Between February 2013 and February 2018, 500 pts were randomized in 28 French centres and received either 4 cycles of GC every 3 weeks or 6 cycles of dd-MVAC every 2 weeks before surgery (neoadjuvant group) or after surgery (adjuvant group). The primary endpoint of the VESPER trial was the progression-free survival (PFS) at 3 years (clinicaltrials.gov NCT 018 12369).


437 patients (88%) received neoadjuvant chemotherapy, 60% of pts received the planned 6 cycles in the dd-MVAC arm and 84% received 4 cycles in the GC arm. Thereafter, 91% and 90% of pts underwent surgery, respectively. Organ-confined response (< ypT3N0) was observed more frequently in the dd-MVAC arm (77% vs 63%, p=0.001). In the adjuvant group, 40% of pts received 6 cycles in the dd-MVAC arm, 81% received 4 cycles in the GC arm. In the perioperative setting of the VESPER trial, PFS at 3 years was improved in the dd-MVAC arm (64% vs 56%, HR=0.77 (95% CI, 0.57-1.02), p=0.066), as was also time to progression (TTP) (3-year rate: 69% vs 58%, HR=0.68 (95% CI, 0.50-0.93), p=0.014). In the neoadjuvant group, the PFS at 3 years was significantly higher for the dd-MVAC arm (66% vs 56%, HR=0.70 (95% CI, 0.51-0.96), p=0.025). In the adjuvant group, the results were not conclusive due to the limited sample size (n=56).


In the VESPER phase III trial, we reported a benefit on PFS at 3 years for the dd-MVAC arm. In the neoadjuvant group, a better bladder tumour local control with a significant improvement on PFS at 3 years were observed in the dd-MVAC arm.
