Overview

AHNSA (Albumin-Hitchhiking Nanobody-STING Agonist) is an experimental immunotherapeutic platform designed to deliver STING (Stimulator of Interferon Genes) agonists systemically while minimizing systemic toxicity. The platform utilizes a nanobody that binds to endogenous albumin, allowing the therapeutic to hitchhike through the circulation and preferentially accumulate in tumor tissues. Once in the tumor microenvironment (TME), the STING agonist activates innate immune pathways, leading to the recruitment and activation of dendritic cells and M1 macrophages, and the subsequent enhancement of CD8+ T cell infiltration and function. AHNSA is primarily being investigated as a programmable adjuvant to improve the efficacy of adoptive cell therapies (ACT), such as CAR-T cells, in treating solid tumors by converting the immunosuppressive TME into a pro-inflammatory environment.
