Smart injectable biogels based on hyaluronic acid bioconjugates finely substituted with poly (β-amino ester urethane) for cancer therapy

Abstract

Development of implantable material to control the release of chemotherapeutics in the body is a promising approach to control cancer cell proliferation; however, implantation requires surgical intervention. Herein, we propose the in situ formation of injectable biogels (IBGs) for the programmed delivery of potent chemotherapeutic drugs. IBGs are developed via cohesive molecular assembly of a polysaccharide-polymer network comprised of hyaluronic acid-poly(β-amino urethane). Biocompatible IBGs could be administrated subcutaneously through a hypodermic needle in vivo to subsequently assemble into a microporous network. The hyaluronic acid-shielded network mimics the natural extracellular matrix, avoiding rapid degradation of IBGs, with a soft texture and adhesiveness facilitating integration with dermal tissues after subcutaneous implantation. The natural-mimicking architecture provides controlled degradation and bioresorbable properties to the IBG network. Subcutaneous administration of IBGs controlled the delivery of a therapeutic agent in a spatio-temporal manner. Therapeutic agents delivered near the tumors in a sustained manner were effectively infiltrates to the thick solid tumors and provide a durable and enhanced anti-tumor response in the B16/OVA melanoma model in vivo. These results indicate that IBGs could be potential medical interventions for the treatment of cancers.
