Eplontersen Ph III trial met co-primary endpoints
 
 
21 June 2022 07:00 BST
 
Eplontersen met co-primary and secondary endpoints in interim analysis of the NEURO-TTRansform Phase III trial for hereditary transthyretin-mediated amyloid polyneuropathy
(ATTRv-PN)
 
New Drug Application filing anticipated based on positive data from interim analysis
 
Positive high-level results from the NEURO-TTRansform Phase III trial in patients with hereditary transthyretin-mediated amyloid polyneuropathy (ATTRv-PN) showed AstraZeneca and Ionis' eplontersen met its co-primary endpoints in a planned interim analysis at 35 weeks. In the trial, eplontersen reached a statistically significant and clinically meaningful change from baseline for its co-primary endpoint of percent change in serum transthyretin (TTR) concentration, reducing TTR protein production. Eplontersen also reached its co-primary endpoint of change from baseline in the modified Neuropathy Impairment Score +7 (mNIS+7), a measure of neuropathic disease progression1, versus external placebo group.
 
High-level results showed the trial also met its secondary endpoint of change from baseline in the Norfolk Quality of Life Questionnaire-Diabetic Neuropathy (Norfolk QoL-DN) showing treatment with eplontersen significantly improved patient-reported quality of life versus external placebo group. In the trial, eplontersen demonstrated a favourable safety and tolerability profile with no specific concerns.
 
ATTRv-PN is a debilitating disease that leads to peripheral nerve damage with motor disability within five years of diagnosis and, without treatment, is generally fatal within a decade3. Eplontersen, formerly known as IONIS-TTR-LRx, is a ligand-conjugated antisense (LICA) investigational medicine designed to reduce the production of TTR protein at its source to treat both hereditary and non-hereditary forms of ATTR2,4-6
 
Teresa Coelho, M.D., a neurologist and neurophysiologist at Hospital Santo António, Centro Hospitalar Universitário do Porto, Portugal and an investigator for the NEURO-TTRansform trial, said: "These encouraging data reinforce the safety profile of eplontersen and demonstrate clear evidence of its potential to provide much needed therapeutic benefit to patients living with hereditary transthyretin-mediated amyloid polyneuropathy."
 
Mene Pangalos, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca, said: "Amyloid transthyretin polyneuropathy is a rare and fatal disease that can affect up to 40,000 people worldwide. These promising results show eplontersen has the potential to be a new and much needed treatment where limited options exist and significant unmet medical need remains."
 
Based on the 35-week interim trial results, the companies will seek regulatory approval for eplontersen and plan to file a new drug application with the US Food and Drug Administration in 2022. ATTRv-PN is expected to be the first indication for which AstraZeneca and Ionis will seek regulatory approval for eplontersen. The results from the 35-week interim analysis of the trial will be submitted for presentation at a forthcoming medical meeting.
 
As part of a global development and commercialisation agreement with Ionis, eplontersen will be jointly developed and commercialised by both companies in the US and will be developed and commercialised in the rest of the world by AstraZeneca (with the exception of Latin America).  
 
Eplontersen was granted Orphan Drug Designation in the US and is also currently being evaluated in the CARDIO-TTRansform Phase III trial for amyloid transthyretin cardiomyopathy (ATTR-CM)4,6, a systemic, progressive and fatal condition that leads to progressive heart failure and death within four years from diagnosis7-9.
 
Notes
 
TTR Amyloidosis
ATTR cardiomyopathy and polyneuropathy are progressive systemic diseases caused by aging or genetic mutations, resulting in misfolded TTR protein and accumulation as amyloid fibrils in the cardiac myocardium and peripheral nerves, respectively2,6-8. In patients with ATTR, both hereditary and wild type (non-hereditary), TTR protein builds up as fibrils in tissues, such as the peripheral nerves and heart, gastrointestinal system, eyes, kidneys, central nervous system, thyroid and bone marrow7,8,10. The presence of TTR fibrils interferes with the normal functions of these tissues8. As the TTR protein fibrils accumulate, more tissue damage occurs and the disease worsens, resulting in poor quality of life (QoL) and eventually death8. Worldwide, there are an estimated 300,000 - 500,000 patients with ATTR-CM10 and about 40,000 patients with ATTRv-PN8.
 
NEURO-TTRansform
NEURO-TTRansform is a global, open-label, randomised trial evaluating the efficacy and safety of eplontersen in patients with ATTRv-PN2,5. The trial has enrolled adult patients with ATTRv-PN Stage 1 or Stage 2 and will be compared to the external placebo group from the TEGSEDI® (inotersen) NEURO-TTR registrational trial that Ionis completed in 20172,5. The final primary endpoint analysis will be completed at week 66 and all patients will be followed until week 85, when they will have the option to transition into the open-label extension trial2. The co-primary endpoints in the interim analysis were percent change from baseline in serum TTR concentration and change in the mNIS+7 versus external placebo group at week 352,5. The mNIS+7 uses highly standardised, quantitative, and referenced assessments to quantify muscle weakness, muscle stretch reflexes, sensory loss, and autonomic impairment1. The secondary endpoint was change from baseline in the Norfolk QoL-DN score versus external placebo group at week 352,5. The Norfolk QoL-DN is a patient-reported questionnaire capturing neuropathy-related QoL11.
 
Eplontersen 
Eplontersen is a LICA investigational medicine designed to reduce the production of transthyretin, or TTR protein, to treat all types of ATTR, a systemic, progressive and fatal disease2,4-6.
