Abstract

Background

The PI3K/AKT/mTORC1 axis is implicated in hormone receptor-positive HER2-negative metastatic breast cancer (HR+ HER2в€’ mBC) resistance to anti-estrogen treatments. Based on link between the BOLERO-2 trial, the mTORC1 inhibitor everolimus in combination with the steroidal aromatase inhibitor (AI) exemestane has changed into a standard treatment plan for clients with HR+ HER2в€’ mBC resistant to prior non-steroidal therapy that is AI. Within the present SOLAR-1 trial, the inhibitor for the PI3K alpha subunit (p110О±) alpelisib in combination with fulvestrant extended progression-free survival (PFS) when comparing to fulvestrant alone in patients with PIK3CA-mutated HR+ HER2в€’ mBC that progressed after/on previous AI treatment. Therefore, two different particles focusing on the PI3K/AKT/mTORC1 axis, specifically everolimus and alpelisib, are for sale to clients progressing on/after previous AI treatment, however it is uncertain how to optimize their use within the practice that is clinical.

Here, we reviewed the available evidence that is clinical from the BOLERO-2 and SOLAR-1 studies to compare effectiveness and safety profiles of everolimus and alpelisib in advanced HR+ HER2в€’ BC treatment.
