NextGen Targeted Drug Combination for Metastatic Cancers
Most of the cancer types would need multiple drugs, including molecularly targeted kinase and aromatase inhibitors, given in sequence or in a combination to reduce the rate of cancer progression to metastatic stage. Systems pharmacology approach to develop a drug combination nanoparticulate platform technology that allows synchronized delivery and retention in the metastatic cancer cells may provide a path to maximize multiple drug target knockout within the same cancer cells to overcome disease progression.
Most of the cancer types including breast and pancreatic cancers would need multiple drugs, including molecularly targeted kinase and aromatase inhibitors, given in sequence or in a combination to reduce the rate of cancer progression to metastatic stage. At metastatic stage, most of the oral drugs, including those of molecularly targeted products and given in combination may have limited disease impact. While a number of highly potent infusion chemotherapeutics given in combination, such as gemcitabine and paclitaxel are effective, they are given sequentially thus non synchronized impact on multiple cancer targets. Systems pharmacology approach provide the framework to develop a drug combination nanoparticulate platform technology that allow synchronized delivery and retention in the metastatic cancer. Our team has made significant progress toward this goal in developing a drug combination assembled in nonparticulate form that synchronized delivery of water soluble gemcitabine and water insoluble paclitaxel to the advancing metastatic breast cancer cells in vivo. These nano-drug particles called DcNP containing gemcitabine and paclitaxel are shown to provide synchronized tissue and cell localization in metastatic 4T1 localized in lung and able to clear tumor cells with good margin of safety. NextGen long-acting and targeted drug combination strategies that may enable synchronized intracellular co-localization of multiple drugs could further refine with model development and validation as a part of systems knowledge in pharmacology.
