  • Publication number: 20260276639
    Abstract: This invention relates to a method of selecting a subject having a cancer for treatment, comprising: i) determining a KAT6A level from a biological sample of the cancer from the subject; ii) selecting the subject for treatment with a cyclin-dependent kinase 4 (CDK4) inhibitor as a single agent or in combination with an antiestrogen, based on the KAT6A level, wherein the KAT6A level is determined to be low, and methods of treatment thereof. It is shown that lower than median KAT6A mRNA levels in metastatic tumor samples of patients with breast cancer qualify as a predictive biomarker for the response to a combination therapy with palbociclib and fulvestrant.
