Evaluation of micelles incorporated into thermosensitive hydrogels for intratumoral delivery and controlled release of docetaxel: A dual approach for in situ treatment of tumors.

ABSTRACT: The in situ gelling hybrid hydrogel system has been reported to effectively concentrate chemotherapeutic drugs at the tumor site and sustain their release for a long period. DTX-micelles (docetaxel-loaded mixed micelles) are able to increase the solubility of DTX in water, and then a high drug loading rate of hydrogels can be achieved by encapsulating the docetaxel-loaded mixed micelles into the hydrogels. The thermosensitive nature of DTX-MM-hydrogels (thermosensitive hydrogels incorporated with docetaxel-loaded mixed micelles) can accelerate the formation of a depot of this drug-loaded system at the site of administration. Therefore, the hydrogels provide a much slower release compared with DTX-micelles and DTX-injection. An in vivo retention study has demonstrated that the DTX-MM-hydrog
