A phase II study of oral infigratinib in adult patients with advanced or metastatic solid tumors with FGFR1-3 gene fusions or other FGFR genetic alterations

This phase II trial studies how well infigratinib works in treating solid tumors that have spread to other places in the body (advanced or metastatic) in patients with FGFR gene mutations such as FGFR1-3 gene fusions or other FGFR genetic alterations. Mutations are any changes in the genetic material (DNA) of a cell. FGFR proteins are involved in cell division, cell maturation, formation of new blood vessels, wound healing, and bone growth, development, and maintenance. FGFR mutations can cause the FGFR protein to become over-active in diseases such as cancer. Infigratinib may stop the growth of tumor cells by blocking FGFR proteins in these tumors.
