ASCO 2023 | THOR: erdafitinib in metastatic urothelial cancer with FGFR alterations

Yohann Loriot, MD, PhD, Gustave Roussy, Villejuif, France, provides an overview of the Phase III THOR trial (NCT03390504), which assessed erdafitinib, a pan-FGFR tyrosine kinase inhibitor, in patients with FGFR-mutant advanced or metastatic urothelial cancer (mUC). Patients were randomized to receive erdafitinib or chemotherapy, and erdafitinib resulted in superior overall-survival (OS), progression-free survival (PFS), and overall response rate (ORR). No new safety indications were additionally reported. This interview took place at the American Society of Clinical Oncology (ASCO) 2023 Annual Congress in Chicago, IL.
