Dovitinib Lactate in Treating Patients With Refractory or Stage 0-I Bladder Cancer With FGFR3 Mutations or Overexpression
- Histologically confirmed early stage urothelial carcinoma of the bladder defined as Ta, T1, or Tis stage; tumor staging must be confirmed by TURBT performed within 42 days prior to registration
- Presence of either an FGFR3 mutation or FGFR3 over-expression within bladder tumor tissue. FGFR3 mutations in exons 7, 10, and 15 will be assessed by polymerase chain reaction (PCR)-single strand conformation polymorphism (PCR-SSCP) sequencing analysis utilizing the CertNDx® molecular grading assay performed in the Clinical Laboratory Improvement Amendments (CLIA)-certified Predictive Biosciences™ laboratories; FGFR3 over-expression will be assessed by standard immunohistochemistry (IHC) analysis performed within the Indiana University Simon Cancer Center Immunohistochemistry (IHC) Core Lab
- Documented BCG-refractory disease defined as failure to achieve a tumor free state after at least 2 prior induction courses of intravesical BCG therapy; NOTE: For patients with residual non-invasive tumors (i.e. Ta, T1, Tis) after an initial 6-week induction course of intravesical BCG therapy, a second induction course of intravesical BCG therapy is required; patients with persistent non-invasive tumors (i.e. Ta, T1, Tis) despite an initial 6-week and second induction intravesical BCG therapy course are considered BCG-refractory and, therefore, eligible for study; patients with non-invasive tumor recurrences (i.e. Ta, T1, Tis) after only an initial 6-week induction course of intravesical BCG therapy are considered BCG-resistant and not eligible for study until persistent non-invasive tumor (i.e. Ta, T1, Tis) is demonstrated after a second induction course of intravesical BCG therapy has been administered; there is no maximum limit on the number of prior BCG therapy courses; in addition, there is no maximum limit on the number of prior non-BCG intravesical therapy courses (i.e. gemcitabine, valrubicin, interferon, mitomycin C, etc.)
