Temperature-Controlled pNIB/PTX Micelles for Improved Paclitaxel Delivery in Ovarian Cancer Treatment

Paclitaxel (PTX) is a widely used anticancer drug for ovarian cancer treatment, but its clinical application is limited by poor water solubility and dose-limiting toxicities. To overcome these challenges, we developed a thermoresponsive, multistep drug delivery system, pNIB/PTX, designed to improve PTX solubility and provide controlled drug release. The pNIB/PTX-3 complex exhibited an initial rapid drug release phase followed by sustained slow release, optimizing both short-term and long-term therapeutic efficacy. At physiological temperatures, the complex demonstrated a precisely controlled drug release mechanism driven by changes in the polymeric micelle structure.
