BALVERSA is a kinase inhibitor indicated for the treatment of adult patients with locally advanced or metastatic urothelial carcinoma that has...susceptible FGFR3 or FGFR2 genetic alterations and...progressed during or following at least one line of prior platinum-containing chemotherapy including within 12 months of neoadjuvant or adjuvant platinum-containing chemotherapy.

We recruited patients aged 12 years or older with advanced or metastatic tumours of any histology (except urothelial cancer) with predefined FGFR1-4 alterations...an objective response was observed in 64 (30% [95% CI 24-36]) of 217 patients across 16 distinct tumour types... RAGNAR results show clinical benefit for erdafitinib in the tumour-agnostic setting in patients with advanced solid tumours with susceptible FGFR alterations who have exhausted other treatment options.

Primary analysis results from RAGNAR, the largest tumor agnostic trial of targeted tx to date, confirm efficacy of erda in heavily pretreated pts with FGFRalt advanced solid tumors. Erda activity was observed in adults and adolescents across tumor types, and across FGFR1-3 gene mutations and fusions.
