Conjugated virus-like particles and uses thereof as anti-tumor immune redirectors

Abstract

Disclosed is a new class of conjugated virus-like particles (VLPs). These conjugated VLPs bind a wide variety of tumors and comprise epitopes recognized by a prior T cell immune response already existing in a host. These epitopes are derived from pathogens or previous vaccinations (such as early childhood vaccines). This provokes the body's pre-existing cytotoxic immunity obtained through previous infection or previous childhood vaccination to be redirected to the tumor cells for the elimination of cancer, and form long-term anti-tumor immunity. The described conjugated VLPs are useful for tailoring a broad range of tumors towards a response from existing immunity circumventing the need to identify tumor antigens or generate tumor-specific immune responses. Importantly, the compositions and methods described herein broadens opportunities for treatment for all cancer types in subjects who previously had un-targetable cancers due to various technological and biological limitations of currently available immuno-therapeutic drugs.
