Medical Uses
Truqap (capivasertib), from AstraZeneca, is a first-in-class oral AKT inhibitor. It is approved in combination with fulvestrant for adults with hormone receptor (HR)-positive, HER2-negative, locally advanced or metastatic breast cancer harboring one or more PIK3CA, AKT1, or PTEN alterations, following progression on at least one endocrine-based regimen.
A newer indication covers PTEN-deficient metastatic castration-resistant prostate cancer, based on the CAPItello-281 trial (approved June 2026 — verify current label wording before relying on this).
Capivasertib is an ATP-competitive inhibitor of all three AKT isoforms (AKT1, AKT2, AKT3), blocking the PI3K/AKT/PTEN signalling pathway that drives survival and proliferation in tumors with pathway-activating alterations.
