Neratinib (HKI-272) is a tyrosine kinase inhibitor[1][2] under investigation for the treatment of breast cancer[3] and other solid tumours.

It is in development for the treatment of early- and late-stage HER2-positive breast cancer.[4]

Like lapatinib and afatinib, it is a dual inhibitor of the human epidermal growth factor receptor 2 (Her2) and epidermal growth factor receptor (EGFR) kinases.[5]

Clinical trials

Neratanib is being developed by Puma Biotechnology. It will be included in the forthcoming I-SPY2 breast cancer trial.[6]

Mechanism of action

Neratinib inhibits the epidermal growth factor receptor by covalently binding with a cysteine side chain in that protein.[7]
