Preclinical Rationale, Clinical Efficacy, and Safety of the Selective AKT Kinase Inhibitor Capivasertib in Metastatic Hormone Receptor-Positive, Human Epidermal Growth Factor Receptor 2-Negative Breast Carcinoma: A Practical Narrative Review

Year: 2026

Type: review

Abstract: Most patients with advanced/metastatic hormone receptor-positive, HER2-negative breast cancer receive first-line therapy with cycline-dependent kinase 4/6 inhibitors plus endocrine therapy. Almost universally, these patients eventually progress due to the emergence of resistant cancer clones. Targeting the PIK3CA/AKT1/PTEN pathway is a way of overcoming resistance. Recently, the oral, selective AKT kinase inhibitor capivasertib has been approved for the treatment of estrogen receptor-positive/human HER2-growth factor receptor-2 advanced BC with alterations in PIK3CA/AKT1/PTEN, in combination with fulvestrant after progression on endocrine therapy. We performed a narrative review to recapitulate the available evidence about capivasertib in the management of advanced hormone receptor-positive, HER2-negative breast cancer, focusing on studies that address preclinical rationale, pharmacology, and clinically relevant problems.
