Study of Infigratinib in Combination With Tamoxifen in Hormone Receptor Positive, HER2 Negative, FGFR Altered Advanced Breast Cancer
The purpose of the study is identify the dose(s) of infigratinib to use in combination with tamoxifen to treat patients with a particular type of advanced breast cancer (hormone receptor-positive, HER2-negative, FGFR-altered breast cancer)
Stanford is currently not accepting patients for this trial.
