SPD1-03 A phase Ib trial of fulvestrant + CDK4/6 inhibitor (CDK4/6i) palbociclib + pan-FGFR tyrosine kinase inhibitor (TKI) erdafitinib in FGFR-amplified/ ER+/ HER2-negative metastatic breast cancer (MBC)

Excerpt:
...a phase Ib trial combining erdafitinib with fulvestrant/palbociclib in patients with ER+/HER2-/FGFR-amplified MBC…Of the 18 evaluable patients: 7 had disease progression, 8 had stable disease (4 of which discontinued treatment due to AE), 3 have not completed their first tumor assessment, 4 are still on treatment; median PFS was 3 months and CBR at 6 months was 28%. However, higher PFS (6 months) was seen in 6/8 patients with high levels of FGFR1 amplification (FISH FGFR1:CEP8 ratio >5; gene copy number >10) and in both patients with FGFR3 amplification.
Secondary therapy:
