High-payload antibody-oligonucleotide-drug conjugates (AODC) for targeted tumor chemo-immunotherapy.

A new class of antibody drugs carrying multiple chemotherapy molecules demonstrates stronger tumor-killing power, especially combined with immunotherapy.

This study introduces antibody-oligonucleotide-drug conjugates (AODCs), a novel programmable ADC modality using noncoding oligonucleotide prodrug scaffolds to expand chemotherapeutic payload capacity while enabling targeted antigen-specific delivery. HER2- and CD38-targeting AODCs carrying gemcitabine prodrug chains demonstrate immunogenic cell death, dendritic cell activation, and enhanced anti-tumor efficacy in combination with PD-1 blockade, supporting AODCs as a generalized platform for chemo-immunotherapy.

Why it surfaced

Technically novel ADC modality concept with distinct mechanism (oligonucleotide prodrug scaffold for high payload) validated in multiple tumor models including hematological; CD38 targeting directly relevant to hematologic malignancies watchlist.
