World Heart Federation consensus on transthyretin amyloidosis cardiomyopathy (A...
Brito, Dulce; Albrecht, Fabiano Castro; de Arenaza, Diego Perez; Bart, Nicole; Better, Nathan; Carvajal-Juarez, Isabel; Conceição, isabel; Damy, ThibaudTransthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive and fatal condition that requires early diagnosis, management, and specific treatment. The availability of new disease-modifying therapies has made successful treatment a reality. Transthyretin amyloid cardiomyopathy can be either age-related (wild-type form) or caused by mutations in the TTR gene (genetic, hereditary forms). It is a systemic disea...
Efficacy and safety of vutrisiran for patients with hereditary transthyretin-me...
Adams, David; Tournev, Ivailo L.; Taylor, Mark S.; Coelho, Teresa; Planté-Bordeneuve, Violaine; Berk, John L.; González-Duarte, AlejandraBackground: The study objective was to assess the effect of vutrisiran, an RNA interference therapeutic that reduces transthyretin (TTR) production, in patients with hereditary transthyretin (ATTRv) amyloidosis with polyneuropathy. Methods: HELIOS-A was a phase 3, global, open-label study comparing the efficacy and safety of vutrisiran with an external placebo group (APOLLO study). Patients were randomized 3:1 ...
Long-term efficacy and safety of inotersen for hereditary transthyretin amyloid...
Brannagan, Thomas H.; Coelho, Teresa; Wang, Annabel K.; Polydefkis, Michael J.; Dyck, Peter J.; Berk, John L.; Drachman, Brian; Gorevic, PeterBackground: Hereditary transthyretin amyloidosis (hATTR/ATTRv) results from the deposition of misfolded transthyretin (TTR) throughout the body, including peripheral nerves. Inotersen, an antisense oligonucleotide inhibitor of hepatic TTR production, demonstrated a favorable efficacy and safety profile in patients with the polyneuropathy associated with hATTR in the NEURO-TTR (NCT01737398) study. We report long...
Design and Rationale of the Global Phase 3 NEURO-TTRansform Study of Antisense ...
Coelho, Teresa; Ando, Yukio; Benson, Merrill D.; Berk, John L.; Waddington-Cruz, Márcia; Dyck, Peter J.; Gillmore, Julian D.; Khella, Sami L.Introduction: AKCEA-TTR-LRx is a ligand-conjugated antisense (LICA) drug in development for the treatment of hereditary transthyretin amyloidosis (hATTR), a fatal disease caused by mutations in the transthyretin (TTR) gene. AKCEA-TTR-LRx shares the same nucleotide sequence as inotersen, an antisense medicine approved for use in hATTR polyneuropathy (hATTR-PN). Unlike inotersen, AKCEA-TTR-LRx is conjugated to a ...
Expert consensus on the monitoring of transthyretin amyloid cardiomyopathy
Garcia‐Pavia, Pablo; Bengel, Frank; Brito, Dulce; Damy, Thibaud; Duca, Franz; Dorbala, Sharmila; Nativi‐Nicolau, Jose; Obici, Laura; Rapezzi, ClaudioTransthyretin amyloid cardiomyopathy (ATTR-CM) is a life-threatening condition with a heterogeneous clinical presentation. The recent availability of treatment for ATTR-CM has stimulated increased awareness of the disease and patient identification. Stratification of patients with ATTR-CM is critical for optimal management and treatment; however, monitoring disease progression is challenging and currently lacks...
Long-term safety and efficacy of patisiran for hereditary transthyretin-mediate...
Adams, David; Polydefkis, Michael; González-Duarte, Alejandra; Wixner, Jonas; Kristen, Arnt V.; Schmidt, Hartmut H.; Berk, John L.Background: Hereditary transthyretin-mediated amyloidosis is a rare, inherited, progressive disease caused by mutations in the transthyretin (TTR) gene. We assessed the safety and efficacy of long-term treatment with patisiran, an RNA interference therapeutic that inhibits TTR production, in patients with hereditary transthyretin-mediated amyloidosis with polyneuropathy. Methods: This multicentre, open-label ex...
Quality of life outcomes in APOLLO, the phase 3 trial of the RNAi therapeutic p...
Obici, Laura; Berk, John L; González-Duarte, Alejandra; Coelho, Teresa; Gillmore, Julian; Schmidt, Hartmut H-J; Schilling, Matthias; Yamashita, TaroIntroduction: Hereditary transthyretin-mediated (hATTR) amyloidosis is a rare, fatal, multisystem disease leading to deteriorating quality of life (QOL). The impact of patisiran on QOL in patients with hATTR amyloidosis with polyneuropathy from the phase 3 APOLLO study (NCT01960348) is evaluated.Methods: Patients received either patisiran 0.3 mg/kg (n = 148) or placebo (n = 77) intravenously once every three we...
Early data on long‐term efficacy and safety of inotersen in patients with hered...
Brannagan, T. H.; Wang, A. K.; Coelho, T.; Waddington Cruz, M.; Polydefkis, M. J.; Dyck, P. J.; Plante‐Bordeneuve, V.; Berk, J. L.; Barroso, F.Background and purpose: Hereditary transthyretin (hATTR) amyloidosis causes progressive polyneuropathy resulting from transthyretin (TTR) amyloid deposition throughout the body, including the peripheral nerves. The efficacy and safety of inotersen, an antisense oligonucleotide inhibitor of TTR protein production, were demonstrated in the pivotal NEURO-TTR study in patients with hATTR polyneuropathy. Here, the l...
A Narrative Review of the Role of Transthyretin in Health and Disease
Liz, Marcia Almeida; Coelho, Teresa; Bellotti, Vittorio; Fernandez-Arias, Maria Isabel; Mallaina, Pablo; Obici, LauraTransthyretin (TTR) is a tetrameric transport protein highly conserved through vertebrate evolution and synthesized in the liver, choroid plexus, and retinal pigment epithelium. TTR transports the thyroid hormone thyroxine and the retinol-binding protein (RBP) bound to retinol (vitamin A). Mutations in TTR are associated with inherited transthyretin amyloidosis (ATTRv), a progressive, debilitating disease that ...
Inotersen preserves or improves quality of life in hereditary transthyretin amy...
Coelho, Teresa; Yarlas, Aaron; Waddington-Cruz, Marcia; White, Michelle K.; Sikora Kessler, Asia; Lovley, Andrew; Pollock, Michael; Guthrie, SpencerObjective: To examine the impact on quality of life (QOL) of patients with hATTR amyloidosis with polyneuropathy treated with inotersen (Tegsedi™) versus placebo. Methods: Data were from the NEURO-TTR trial (ClinicalTrials.gov Identifier: NCT01737398), a phase 3, multinational, randomized, double-blind, placebo-controlled study of inotersen in patients with hATTR amyloidosis with polyneuropathy. At baseline and...
