The present disclosure is directed to a drug delivery system in which urate oxidase and metal-based nanoparticles for hydrogen peroxide degradation are loaded in a temperature-sensitive nanocarrier, and a pharmaceutical composition for treating hyperuricemia-related disease comprising the drug delivery system. In the drug delivery system of the present disclosure, urate oxidase and metal-based nanoparticles for hydrogen peroxide degradation are positioned close to each other, thereby effectively removing the toxic substance hydrogen peroxide (H2O2) generated during uric acid degradation. The drug delivery system of the present disclosure may be developed as an active ingredient of a drug for preventing or treating hyperuricemia-related disease.
