While treating brain tumors, the power of therapeutics is often blocked by various drug delivery barriers in the brain. These include blood-brain tumor barriers, destabilizing effects in blood circulation, and low tumor functionality.
To combat these issues, researchers at the University of California, Davis have developed a nano-delivery approach, more specifically referred to as the “Sequential Targeting in Crosslinking” (STICK) strategy. As part of their approach, the researchers have developed two types of telodendrimers (structured building blocks that aid in drug delivery). The telodendrimers work to overcome the current problems of brain therapeutics as stated above. The STICK nanoplatform has increased loading capacity, greater micellar stability, and a multistage targeting approach. Experimentation in orthotopic (tissue transplant placed into its natural location) brain tumor models has proven the nano platform strategy to produce anti-cancer success with greater survival times. Extending the application to imaging and therapy, this invention also shows great potential in aiding drug delivery efficacy in brain tumors by use of image-guiding. In essence, the new approach shows promise in improving the management and overall survival rate of brain tumor patients.
Researchers at the University of California, Davis have developed an approach to improve drug delivery to tumors and metastases in the brain. Their multi-barrier tackling delivery strategy has worked to efficiently impact brain tumor management while also achieving increased survival times in anti-cancer efficacy.
