NCT00320385 📎

Regimen

Experimental
Lapatinib 1000 mg PO daily + trastuzumab 2 mg/kg weekly.
Control
Lapatinib 1500 mg PO daily monotherapy.

Population

HER2-positive metastatic breast cancer with disease progression on prior trastuzumab-based regimens.

Key finding

EGF104900 was the first trial to prove dual HER2 blockade (lapatinib + trastuzumab) without chemotherapy improves OS in pretreated HER2+ MBC. Supported the mechanistic rationale that later drove CLEOPATRA and APHINITY.
