Development and evaluation of paclitaxel nanoemulsion for cancer therapy

Tocosol™ is a tocopherol-based paclitaxel (PTX) nanoemulsion consisting of α-tocopherol (α-T) isomer of vitamin E as a solubilizer and vitamin E TPGS as the primary emulsifier. Despite its positive attributes in early clinical studies, it failed the pivotal phase III clinical trials. The long-term goal of this work was to reformulate Tocosol™. In this study, Tocosol™ formulation was optimized by replacing the α-T isomer with the more...
