Of 232 patients with CCA who underwent molecular screening, 39 (16.8%) had FGFR alterations (21 [9.1%] fusions and 19 [8.2%] mutations). Overall, 22 (9.5%) eligible pts (median age, 52 [range, 29–69] years) were enrolled and received treatment. Median follow-up was 22.4 (range, 2.3–47.0) months; median treatment duration was 6.2 (range, 1.5–35.6) months. All 22 pts received ≥1 line of prior systemic therapy and 12 (55.0%) pts had ≥2 prior lines of therapy. The ORR was 40.9% (95% CI, 20.7%–63.6%) and median time to response was 1.8 (range, 1.5–5.6) months. Median DOR was 7.3 (95% CI, 3.7–17.5) months, median PFS was 5.6 (95% CI, 3.6–12.7) months, and median OS was 40.2 (95% CI: 9.9–not estimable) months...Asian pts with advanced CCA and FGFR alterations treated with erdafitinib had durable efficacy and a manageable safety profile, supporting the earlier findings of erdafitinib benefit in this population.
