Key Factors Driving the Hereditary Transthyretin Amyloidosis (hATTR) Market
Rising hATTR Prevalence
The overall prevalence of hATTR is gradually increasing, driven by improved diagnosis, genetic testing, and disease awareness, which is supporting market expansion. In the US, there were ~18,000 diagnosed prevalent cases of hATTR in 2025, which are expected to increase further by 2036.
Rising Opportunities in Targeted Biologics and JAK Inhibitors
The hATTR market is driven by increasing opportunities in RNA-based therapies and emerging gene-editing treatments, which offer deeper TTR suppression, improved outcomes, and potential long-term or curative effects. Growing focus on siRNA, antisense, and CRISPR-based approaches is expected to transform future disease management.
Emerging hATTR Competitive Landscape
Some of the hATTR drugs in clinical trials include nexiguran ziclumeran (nex z), nucresiran, and others.
Hereditary Transthyretin Amyloidosis (hATTR) Overview and Diagnosis
Hereditary Transthyretin Amyloidosis (hATTR) is a rare, inherited disorder caused by mutations in the transthyretin (TTR) gene, leading to misfolded protein deposits (amyloid) in tissues. It primarily affects the peripheral nerves (hATTR-PN) and the heart (hATTR-CM), resulting in progressive neuropathy and cardiomyopathy. The disease shows variable penetrance and clinical heterogeneity, often causing delays in diagnosis. If untreated, hATTR can lead to severe disability and early mortality. Current treatments focus on stabilising or reducing TTR protein production to slow disease progression.
Hereditary Transthyretin Amyloidosis (hATTR) Diagnosis
Diagnosis is often challenging due to its clinical heterogeneity and overlap with other neuropathies and cardiomyopathies. It is confirmed through genetic testing to identify pathogenic TTR gene mutations, along with tissue biopsy demonstrating amyloid deposits using Congo red staining with apple-green birefringence under polarised light. Common biopsy sites include the abdominal fat pad, salivary gland, gastric mucosa, or affected nerve tissue, offering both invasive and less invasive diagnostic options. In cases of cardiac involvement, echocardiography, cardiac MRI, and nuclear scintigraphy (e.g., bone-avid tracers) help detect transthyretin cardiac amyloid deposition. Early and accurate diagnosis is critical to initiate therapy before irreversible neurological or cardiac damage occurs.
Hereditary Transthyretin Amyloidosis (hATTR) Treatment
Treatment focuses on reducing, stabilising, or silencing transthyretin (TTR) protein production to slow disease progression. Approved therapies include TTR stabilisers (tafamidis) and gene-silencing agents (patisiran, inotersen, vutrisiran, eplontersen) that reduce abnormal TTR levels. These treatments are most effective when initiated early and primarily aim to delay neurological and cardiac decline rather than reverse existing damage. Supportive care is also used to manage symptoms and improve quality of life.
Hereditary Transthyretin Amyloidosis (hATTR) Unmet Needs

Hereditary Transthyretin Amyloidosis (hATTR) Drug Updates
Drug Class Insights
Although there is currently no curative therapy for hATTR, early diagnosis and timely intervention play a critical role in improving patient outcomes and slowing disease progression. Current disease-modifying treatments include TTR stabilisers such as tafamidis, which prevent TTR protein misfolding and subsequent amyloid fibril formation, thereby reducing progression of organ damage, particularly in cardiomyopathy. Gene-silencing therapies, including patisiran, inotersen, eplontersen, and vutrisiran, act by reducing hepatic production of both mutant and wild-type TTR protein, leading to a significant decrease in circulating amyloidogenic protein levels and slowing neuropathy progression. While no approved therapies specifically target amyloid fibril clearance, this remains an important emerging area of research with several investigational approaches aimed at enhancing amyloid removal.
Importantly, the emerging pipeline is increasingly focused on next-generation disease-modifying and potentially curative approaches, including CRISPR-based gene-editing therapies and novel RNA-targeting platforms designed to deliver deeper and more durable TTR suppression.
Liver transplantation, once considered a treatment option to eliminate mutant TTR production, is now rarely used due to the availability of effective RNA-based therapies. In addition, comprehensive symptomatic management remains essential, addressing neuropathic pain, autonomic dysfunction, cardiac complications, and overall functional impairment to improve quality of life. The next major evolution in the treatment landscape is gene-editing therapy, exemplified by Nexiguran ziclumeran, a CRISPR-Cas9-based approach designed to permanently reduce TTR production and potentially offer a one-time curative strategy for hATTR amyloidosis.
Overall, the launch of first-in-class therapies, improved diagnostic approaches, and increasing disease awareness are expected to drive steady growth in the 7MM hATTR market from 2022-2036, with strong commercial implications for both marketed products and emerging pipelines.
