Study Summary

This trial is testing a combination of three drugs to treat metastatic breast cancer that is positive for estrogen receptors, negative for human epidermal growth factor receptors, and has amplified fibroblast growth factor receptors.

Who is the study for?
This trial is for adults with ER+/HER2-/FGFR-amplified metastatic breast cancer who can take oral meds, have evaluable disease and biomarker-determined tissue. They must be in good physical condition (ECOG 0-1), not of childbearing potential or meet post-menopausal criteria, and have had at most one chemo but no FGFR inhibitors in the metastatic setting.Check my eligibility
What is being tested?
The study tests the combination of fulvestrant, palbociclib, and erdafitinib's safety and early effectiveness on patients. It's an open-label phase Ib trial where everyone knows what treatment they're getting, conducted across multiple institutions.See study design
What are the potential side effects?
Possible side effects include issues related to eye toxicity due to erdafitinib; fatigue, nausea, low blood counts from palbociclib; and hormonal changes or injection site reactions from fulvestrant. Each drug has its own profile of potential side effects.
