A Phase II Study of Erdafitinib in Patients Whose Tumors Have an FGFR Alteration


Full Title

A Phase 2 Study of Erdafitinib in Subjects with Advanced Solid Tumors and FGFR Gene Alterations


Alterations in a protein called FGFR can make cancers grow more rapidly, leading to the development and spread of cancer cells. The purpose of this study is to assess the safety and effectiveness of the investigational drug erdafitinib in adults with advanced cancers containing alterations in the FGFR protein.

Erdafitinib blocks the activity of the FGFR alteration, which may slow or stop the growth of cancer cells. The FDA has approved erdafitinib as a treatment for some cancers of the bladder and/or urinary tract that have an FGFR alteration, but the drug has not been approved as a treatment for any other cancers. It is taken orally (by mouth).


To be eligible for this study, patients must meet several criteria, including but not limited to the following:

  • Patients must have an inoperable, locally advanced, or metastatic solid tumor containing an FGFR alteration.
  • Patients’ cancers must persist despite at least one prior regimen of therapy for advanced disease.
  • At least 30 days must pass between the completion of prior therapy and entry into the study.
  • This study is for patients age 18 and older.
