Overview

This combination therapy consists of BO-112, an intratumoral viral mimetic, administered alongside the PD-1 inhibitor nivolumab and stereotactic ablative radiotherapy (SABR). BO-112 is a nanoplexed formulation of polyinosinic:polycytidylic acid (poly I:C) and polyethyleneimine that acts as a double-stranded RNA analog. It triggers an immune response by activating Toll-like receptor 3 (TLR3), melanoma differentiation-associated protein 5 (MDA-5), and protein kinase R (PKR), effectively mimicking a viral infection within the tumor microenvironment. This activation leads to dendritic cell maturation, increased CD8+ T-cell infiltration, and the induction of type I interferons. The combination is specifically being evaluated in Phase Ib/II clinical trials for patients with metastatic non-small cell lung cancer (NSCLC) who have progressed on prior PD-1/PD-L1 checkpoint inhibitor therapy, aiming to overcome resistance by turning "cold" tumors "hot."
