Seventy two FGFR-positive patients were treated with rogaratinib, with 63 evaluable for response. Clinical responses were observed in tumor types not previously associated with FGFR alterations, including a partial remission (PR) in a patient with a FGFR1 mRNA-positive adenoid cystic carcinoma of the tongue and a PR in a FGFR3 mRNA-positive head and neck squamous cell carcinoma patient.
