About one-third of patients experienced an objective response with BALVERSA™ based on BIRC assessment1,2
The efficacy of BALVERSA™ was studied in a multicenter, open-label, single-arm phase 2 trial. There were 87 patients eligible for the efficacy analysis; these were patients with locally advanced or metastatic urothelial carcinoma who had had at least 1 prior platinum-based chemotherapy regimen. The major efficacy outcome measures were objective response rate (ORR = complete response [CR] + partial response [PR]) and duration of response (DOR).
Responders included patients who had previously not responded to anti PD-L1/PD-1 therapy
*Both responders had FGFR3-TACC3_V1 fusion.
†One patient with an FGFR2-CASP7/FGFR3-TACC3_V3 fusion is reported in both FGFR2 fusion and FGFR3 fusion above.
Median duration of response was 5.4 months based on BIRC assessment1
