The Type dimension of Neoantigen Targeted Therapy segmentation distinguishes five principal platforms: peptide‑based vaccines, mRNA‑based vaccines, DNA‑based vaccines, dendritic‑cell (DC) vaccines, and adoptive cell therapies such as TCR‑engineered T cells. Peptide vaccines, the earliest format, capture a modest share of the market (<10%) due to limited immunogenicity and manufacturing complexity. mRNA platforms have accelerated to roughly 35% of total revenues, propelled by rapid design cycles and scalable production. DNA vaccines contribute about 15%, offering stability advantages but facing delivery hurdles. DC vaccines, representing ~12%, leverage ex‑vivo antigen loading to personalize therapy, yet their labor‑intensive process constrains scale. Adoptive cell therapies, now accounting for ~28% of the market, combine neoantigen specificity with potent cytotoxicity, driving premium pricing and high R&D investment. Collectively, these types shape the overall market size by allocating capital, pipeline focus, and commercial revenue across distinct technological pathways.
