Overview

Paclitaxel + vistusertib is a combination therapy consisting of the chemotherapeutic agent paclitaxel and the targeted small molecule inhibitor vistusertib. Paclitaxel is a microtubule-stabilizing agent that disrupts cell division by inhibiting microtubule depolymerization, leading to mitotic arrest and apoptosis in cancer cells. Vistusertib (AZD2014) is an oral dual inhibitor of mTOR complexes 1 and 2 (mTORC1/2), which are key regulators of cell growth, proliferation, survival, and resistance mechanisms in cancer. The combination has been investigated primarily for platinum-resistant high-grade serous ovarian carcinoma (PR-HGSC) and squamous non-small cell lung cancer (SqNSCLC). Early-phase clinical trials demonstrated manageable toxicity profiles with evidence of tumor shrinkage in both ovarian and lung cancers; however, larger randomized studies did not show significant improvement in progression-free or overall survival compared to standard chemotherapy alone[1][3][4][6].
