Combination index analysis demonstrated strong synergy between capivasertib and B-Raf inhibitors in melanoma cells.

Mechanistic studies revealed that capivasertib effectively suppressed Akt signaling. Synergism was abolished in Akt-overexpressing cells, confirming Akt's role in the observed combination effects. The combination treatments significantly reduced tumor growth, with tumor volumes in the capivasertib-vemurafenib and capivasertib-encorafenib groups reduced by ~70% relative to control.
