FGFR-3 Inhibitor Has Early Clinical Activity in Advanced Urothelial Cancer

The fibroblast growth factor receptor-3 (FGFR-3) inhibitor TYRA-300 has been found safe with dose-dependent responses and disease control in the Phase I SURF301 trial. The study included 41 patients who had been heavily pre-treated for their advanced solid tumors with activating FGFR3 mutations/fusions, bringing the hope of avoiding toxicities from the use of non-specific pan-FGFR inhibition.   The findings were reported by Ben Tran, MBBS, FRACP, at the 2024 EORTC-NCI-AACR 2024 Molecular Targets and Cancer Therapeutics Symposium held in Barcelona, Spain. Tran is a Medical Oncologist and Associate Professor at the Peter MacCallum Cancer Centre Melbourne, Australia. He also is Chair of the Germ Cell Tumour Subcommittee for the Australian and New Zealand Urological and Prostate Cancer Trials.
