Definitions
- the present invention relates to a polymer micelle composition for the treatment of resistant cancer and a method of manufacturing the same.
- Taxane-based anticancer agents have been successfully used for the treatment of breast cancer, ovarian cancer, lung cancer or prostate cancer.
- paclitaxel and docetaxel which are taxane-based anticancer agents, have very low solubility in water and are required to be solubilized with a nonionic surfactant or the like. Therefore, formulations solubilized with cremopoa and polysorbate as nonionic surfactants are commercially available as Taxol® or Taxotel®.
- the Taxol® and Taxotel® show excellent anticancer efficacy, but there are side effects such as hypersensitivity by solubilizers, and research on new formulations without side effects is being conducted.
- anticancer agents such as taxane are widely used as an excellent anticancer effect, but there is a problem that resistance to anticancer agents is expressed.
- Mechanisms that cause cancer cell resistance vary, but one of the well-known causes is the promotion of extracellular release of anticancer agents by overexpression of P-glycoprotein.
- P-glycoprotein overexpression there is an attempt to use an inhibitor that inhibits the function of P-glycoprotein.
- P-glycoprotein inhibitors are known as verapamil, ketoconazole or cyclosporin. These substances have been studied as inhibitors of P-glycoprotein to reduce oral absorption of anticancer drugs due to P-glycoprotein overexpressed in the intestinal wall upon oral administration of an anticancer agent such as taxane.
- Cyclosporin is a poorly soluble drug, and a composition using cremopoa as a solubilizer is developed and marketed as an intravenous injection or an oral drug under the brand name Sandimun®, and a composition solubilized by microemulsion technology is developed as an oral drug of Neooral®. It is.

- the present invention also provides a method for preparing the polymer micelle composition for treatment of resistant cancer.
- the polymer micelle composition for treatment of resistant cancer includes an amphiphilic block copolymer of the present invention and a polylactic acid alkali metal salt including at least one carboxyl group at an arbitrary end thereof, and thereby the EPR (Enhanced Permeability and Retention) effect.
- EPR Enhanced Permeability and Retention
- the cancer tissue contains taxane mixed with a P-glycoprotein inhibitor, it shows an excellent anticancer effect against cancer cells expressing resistance due to the overexpression of P-glycoprotein by an anticancer agent, and hypersensitivity reactions due to the use of a solubilizer.
- the advantage is that it does not happen.
- it is possible to reduce side effects due to systemic administration of cyclosporin by allowing cyclosporin to be highly distributed in cancer tissues.
- Figure 1 was analyzed the particle size of the polymer micelle encapsulated with paclitaxel and cyclosporin in accordance with an embodiment of the present invention using dynamic light scattering method, the results of the weight conversion (Weight) average distribution);

- the polymer micelle composition for treatment of resistant cancer according to the present invention is characterized in that it comprises taxane, cyclosporin and amphiphilic diblock copolymer in order to solubilize taxane and cyclosporine together.
- the polymer micelles may be nanoparticles, and micelles or nanoparticles may specifically be particles having a particle diameter of 10 to 200 nm.
- Taxane and cyclosporin are poorly water soluble and require special solubilization techniques or compositions to be administered to the human body. Therefore, in the preparation of two existing drug groups, solubilization is carried out using an ethanol organic solvent and cremopoa or polysorbate as a surfactant. However, when the two types of surfactant are administered to the human body through a vein or the like, there is a side effect that causes a severe hypersensitivity reaction, so that careful administration or pretreatment is required. Therefore, the present invention provides a composition that does not cause side effects such as hypersensitivity even when taxane and cyclosporin are simultaneously administered through a vein.

Experimental results are shown in FIG. 6.
- composition 11 in the case of the cyclosporin-containing polymer micelle composition (composition 11) -treated group, administration alone does not affect anticancer activity at all, and it can be seen that cancer growth volume is larger than that of the control group.
- the paclitaxel-containing polymer micelle composition (composition 12) or the mixed polymer micelle composition (composition 13) -treated group cancer growth inhibition was shown compared with the control group, and especially the mixed polymer micelle composition (composition 13) -treated group Compared with the paclitaxel-containing polymer micelle composition (composition 12) -treated group, it showed a high rate of cancer inhibition.
