Transthyretin amyloidosis (ATTR) remains a relentlessly progressive and often fatal disorder driven by the misfolding and deposition of transthyretin protein in peripheral nerves, cardiac tissue, and multiple organs. Hereditary ATTR (ATTR-v) manifests as polyneuropathy and debilitating motor impairment, while wild-type ATTR (ATTR-wt) primarily affects cardiac function in elderly populations, leading to heart failure and diminished quality of life. Historically, treatment options were limited to organ transplantation and symptomatic management, resulting in unsatisfactory outcomes and high mortality rates within a decade of diagnosisxceptionallyew disease-modifying therapies existed.

A surge of breakthroughs in clinical development, regulatory milestone achievements, and delivery innovations has collectively redefined the ATTR therapeutic landscape. Most notably, the U.S. Food and Drug Administration’s acceptance and subsequent approval of eplontersen after a PDUFA action date in late 2023 underscored the transformative potential of ligand-conjugated antisense oligonucleotide (LICA) technology in optimizing hepatic uptake and enhancing potency compared to first-generation optionsiteturn2search1. Concurrently, inotersen’s long-term safety and efficacy profile, demonstrated over three years of treatment in open-label extension studies, has solidified confidence in antisense oligonucleotides as a durable disease-modifying approachiteturn3search4. Beyond regulatory clearance, manufacturers have pioneered GalNAc conjugation and refined subcutaneous dosing regimens, reducing administration frequency while preserving robust therapeutic benefit and mitigating adverse events.

Since their imposition in 2018 and 2019, U.S. Section 301 tariffs on a broad range of imports from China have persisted into 2025, particularly affecting specialty chemical reagents and oligonucleotide synthesis inputs. While carrier molecules and active pharmaceutical ingredients (APIs) in commercial ATTR therapies continue to benefit from zero duty rates under existing Harmonized Tariff Schedule provisions, upstream supply chains for amidites, linkers, and solvents have experienced ad valorem duties of up to 25 percent, challenging cost structures and raw material sourcing strategiesiteturn0news12. Tariff exclusion extensions granted through May 2025 have offered temporary relief for a subset of laboratory equipment and reagents, but the looming reinstatement of duties on key process inputs has compelled contract development and manufacturing organizations (CDMOs) to regionalize synthesis and pursue dual-sourcing arrangementsiteturn1news12. Furthermore, scheduled tariff rate increases for various industrial components, set to take effect on January 1, 2025, underscore the necessity for agile supply chain optimization and proactive inventory planning to sustain uninterrupted production of antisense oligonucleotide therapiesiteturn1search4.

The ATTR antisense oligonucleotide market exhibits nuanced dynamics across multiple segmentation dimensions that underscore targeted opportunities and strategic focal points. Segment-wise, drug type analysis reveals eplontersen’s rapid uptake driven by its GalNAc-conjugated mechanism and monthly subcutaneous administration, contrasted with inotersen’s established weekly dosing and evolving safety monitoring protocols. Distribution channel performance highlights the central role of specialty pharmacies-particularly within private and public hospital networks-in facilitating patient access and adherence, while online pharmacy platforms gain traction through patient convenience and home delivery services. End user insights denote that specialist clinics continue to lead early diagnosis and treatment initiation, whereas home healthcare modalities, encompassing both self-administration and visiting nurse services, are becoming instrumental in expanding patient reach and reducing hospital burden. Hospitals, stratified into private and public institutions, maintain significance as infusion centers for intravenous oligonucleotide therapies, even as nursing homes, spanning assisted living and long-term care facilities, emerge as key venues for ongoing disease management. The route of administration segmentation further accentuates subcutaneous injection’s dominance, with intravenous infusion reserved for select cardiomyopathy indications and oral administration remaining largely in preclinical exploration. Patient type analysis distinguishes familial cases with early onset from wild-type presentations in older demographics, and therapy line classification, from first through third line, delineates evolving prescriber preferences and treatment algorithms. Disease stage segmentation underscores the critical imperative of early-stage intervention to maximize neurological preservation and quality-of-life outcomes, with pre-symptomatic identification programs poised to redefine screening paradigms.

Geographic factors continue to shape the strategic deployment and adoption of antisense oligonucleotide therapies for ATTR.
