Decreased adhesivity receptor-targeted nanoparticles for Fn14-positive tumors

Metastatic triple negative breast cancer (TNBC) still carries a dismal prognosis with the current treatment paradigms. The effectiveness of drug treatment for many solid tumors such as TNBC is limited by tumor heterogeneity, lack of tumor specificity, off-target toxicities, and transient therapeutic action(s). Strategies that provide tumor-specific, sustained concentrations of drugs to the tumors and tumor receptor-specific binding, while reducing off-target effects are needed to ensure sufficient tumor cell uptake within the primary and metastatic tumor microenvironment. The decreased non-specific adhesivity, receptor-targeted nanoparticle formulations (“DART” nanoparticles) of the invention were assessed for clinical potential in directing biological agents to the cell surface receptor Fn14, which is expressed in many solid cancer types, including TNBC primary tumors and metastatic lesions. They are contemplated for use against solid tumors, particularly brain tumors such as glioblastoma and breast cancer, including metastatic breast cancer.

NOVEL CERIUM OXIDE NANOCOMPLEX AND A COMPOSITION FOR PREVENTING OR TREATING CEREBRAL INFARCTION COMPRISING THE SAME
20230089986 · 2023-03-23 · ·

A cerium oxide nanocomplex, a composition containing the cerium oxide nanocomplex as an active ingredient, and their uses for preventing or treating brain edema are disclosed. The composition can be used as an efficient nanoparticle therapeutic composition by applying a biocompatible polymer composed of an optimal combination to significantly improve the biomedical stability, biocompatibility, and efficiency of the production process of nanoparticles while maintaining the nanoparticles' excellent inhibitory activity against inflammation. In particular, the composition may be used as an effective therapeutic agent that may help patients with severe cerebral infarction recover their neurological function and greatly improve their survival rate by inhibiting secondary inflammatory response and minimizing tissue injury caused by brain edema.

Polymer materials for delivery of short-chain fatty acids to the intestine for applications in human health and treatment of disease

Provided herein are polymer materials that find use in, for example, delivery of short-chain fatty acids.
