Within the market taxonomy, the Types dimension classifies GalNac conjugates according to molecular architecture and generation. First‑generation GalNAc‑siRNA conjugates, built on a tri‑antennary GalNAc ligand linked to a 19‑21 mer siRNA, remain the bulk of approved products and represent roughly 55 % of the type‑based market share, owing to their established manufacturing pathways. Second‑generation constructs incorporate chemically stabilized siRNA backbones (e.g., 2′‑O‑methyl, phosphorothioate) and enhanced ligand valency, capturing about 25 % as they promise improved potency and reduced dosing frequency. GalNAc‑antisense oligonucleotides, which employ a similar targeting moiety but differ in mechanism of RNase H recruitment, occupy an emerging 12 % niche, reflecting early‑stage clinical pipelines. Finally, hybrid platforms that combine GalNAc targeting with novel delivery vectors such as lipid nanoparticles constitute the remaining 8 %, driven by exploratory collaborations. The proportional weight of each type directly influences total market size, because development cost, regulatory complexity, and pricing strategy vary markedly across these molecular subclasses.
