The application dimension of the Oligonucleotide Therapy segmentation delineates the therapeutic areas that drive market revenue. Oncology commands the largest share, accounting for roughly 35 % of total sales, as a growing pipeline of antisense and siRNA agents targets oncogenic drivers and tumor‑specific transcripts. Rare diseases follow closely at 30 %, reflecting the high unmet need and premium pricing for precision medicines addressing genetic mutations. Cardiovascular applications represent 15 % of the market, propelled by antisense approaches to modulate lipid metabolism and vascular inflammation. Neurology contributes 10 %, with antisense and miRNA therapeutics aimed at neurodegenerative pathways such as Huntington’s and ALS. Infectious diseases, including viral and bacterial targets, hold a modest 5 % share, while an “Others” category—encompassing ophthalmology, dermatology, and metabolic disorders—also accounts for 5 %. Together, these application segments collectively shape the overall market size, each adding distinct value through disease‑specific adoption rates, reimbursement dynamics, and regulatory pathways.
