Attruby is a TTR stabilizer developed for treating patients with transthyretin amyloidosis (ATTR) who have heart involvement (cardiomyopathy). 3 Amsterdam, Netherlands – 27 Aug 2023: Acoramidis improves outcomes in patients with transthyretin amyloid cardiomyopathy (ATTR-CM) compared with placebo, according to late breaking research presented in a Hot Line session today at ESC Congress 2023. Mechanisms of Action: TTR Stabilizer. While BridgeBio's Attruby, an oral TTR stabiliser, has the same mechanism of action as tafamidis, Alnylam's asset is a wholly separate modality. BridgeBio plans on submitting a new drug application to the FDA by the end of this year 12. Modality: Small Molecule BridgeBio’s acoramidis (Attruby), an oral, second-generation stabilizer of the TTR protein, has been approved by the FDA for the treatment of ATTR-CM (transthyretin amyloid cardiomyopathy). 3 , 1 Tafamidis binds to transthyretin tetramers at the thyroxin binding sites, stabilizing the tetramer, reducing the Mechanism of Action. Advice to Patients. 1 Although they share a mechanism of action Background: Transthyretin amyloid cardiomyopathy is characterized by the deposition of misfolded monomeric transthyretin (TTR) in the heart. BridgeBio's shares jumped 10% in the wake of Alnylam's data release. 29. The most common side effects were mild and included Acoramidis has the potential to be an effective and safe alternative to tafamidis for the treatment of ATTR-CM. Food and Drug Administration (FDA) has approved acoramidis to reduce the risk of cardiovascular death and cardiovascular-related hospitalizations in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). Acoramidis binds TTR at thyroxine binding sites and slows dissociation of the TTR tetramer into its constituent monomers, the rate-limiting step in amyloidogenesis. Mechanism of Action. Acoramidis. 6MWT >100 m. . In patients with transthyretin amyloid cardiomyopathy (ATTR-CM), treatment with acoramidis reduced all-cause mortality and cardiovascular disease hospitalization, compared with placebo, according to findings from the ATTRibute-CM trial presented at ESC Congress 2023. – As previously announced, the primary endpoint (a hierarchical analysis inclusive of all-cause mortality and frequency of cardiovascular-related hospitalization) was met (Win Ratio of 1. While acoramidis is not Mechanism of action Acoramidis is a tetrameric transthyretin (TTR) stabilizer. These results demonstrate a quantitative relationship between TTR stabilization, the mechanism of action of tafamidis, and accepted laboratory and patient-based outcomes in ATTR-CM. Adding to the growing understanding of the benefit-risk profile for acoramidis in ATTR-CM, Both therapies address the root cause of ATTR-PN by reducing the production of abnormal transthyretin (TTR) protein, albeit through different mechanisms of action. The Orphan Drug is awaiting FDA approval for the treatment of transthyretin amyloid cardiomyopathy (ATTR-CM). - Acoramidis treatment led to a highly significant reduction in all-cause mortality (ACM) and recurrent cardiovascular-related hospitalizations (CVH) at Month 30 compared About Attruby™ (acoramidis) Attruby is the only near-complete (≥90%) stabilizer of Transthyretin (TTR) approved in the U. Notably, there are also other brand new drugs currently under investigation for the treatment of ATTR. This case study not only highlights a fascinating mechanism of action but also serves as an excellent example of how to leverage structural data to This is the first and only FDA approved therapy that specifies near-complete TTR stabilization (≥90%). 0001) and the 12. One such example is acoramidis (previously known as AG-10) , which is also a stabilizer of the TTR tetramer, although its mechanism of action differs from that of the previous drugs . 6 Acoramidis has significantly higher affinity to stabilize TTR than either diflunisal or tafamidis, and was modeled after the protective T119M TTR mutation (resulting in a more acoramidis 800 mg twice daily or placebo for 30 months. In addition to vutrisiran, BridgeBio Pharma has reported positive phase 3 results with its agent, acoramidis, which has a mechanism of action similar to tafamidis. According to a news release from manufacturer BridgeBio, acoramidis “was designed to mimic a naturally occurring ‘rescue mutation’ of the TTR gene”—T119M—targeting destabilization of the native TTR tetramer, the root cause of ATTR-CM. The treatment also showed consistent improvements in patients' quality of life and heart health, as measured by several markers of mortality, morbidity, function, and quality In the 12-month topline results of the ATTRibute-CM trial, acoramidis, a treatment for symptomatic transthyretin amyloid cardiomyopathy, did not meet its primary endpoint, BridgeBio Pharma Mechanism of action. 463 to 0.

Acoramidis binds TTR at thyroxine binding sites and slows dissociation of the TTR tetramer into its Despite its simple structure, the molecule has a fascinating mechanism of action, history, and rationale for differentiation. Coadministration with UGT inducers can potentially decrease acoramidis exposure. Researchers previously identified a super-stabilizing TTR mutation (T119M) that reduces the dissociation rate of transthyretin tetramers by over 33-fold compared to wild-type transthyretin [19, 27]. TTR amyloidogenesis and TTR stabilization by tafamidis (a). Avoid or Use Alternate Drug. Company: BridgeBio Pharma Indication: ATTR-CM Fig. PALO ALTO, Calif. Tafamidis is a small molecule that stabilizes the transthyretin (TTR) protein, preventing its dissociation into monomers, which can misfold and form amyloid fibrils. This prevents misfolding of the TTR protein and inhibits the formation of TTR amyloid fibrils and the subsequent deposition of these insoluble protein clusters in the heart and peripheral nerves. These revelations could significantly influence treatment paradigms and provide new avenues for therapeutic intervention. 12. Unlike tafamidis, which shares a similar mechanism, acoramidis has demonstrated promising results in recent clinical trials. Acoramidis is a potent and highly selective oral stabilizer of the TTR protein. The model structure will be Acoramidis has the potential to be an effective and safe alternative to tafamidis for the treatment of ATTR-CM. 2 Pharmacodynamics Tafamidis has been available since 2019, but vutrisiran has a different mechanism of action.

TTR is a tetrameric protein that can be destabilized by mutations in TTR, resulting in its dissociation into monomers that rapidly misfold and misassemble into aggregates, including pathologic structures associated with TTR amyloidosis [23, 40–45]. Pharmacokinetics studies showed a time to maximum concentration of less than 1 h and a half-life of ≈25 h . This mutation destabilizes the protein’s quaternary structure, making it more vulnerable to dissociation compared to the wild-type structure [ 21 , 24 ]. – Acoramidis demonstrated the earliest known time to separation in cardiovascular outcomes in the ATTRibute-CM study (3 months), with statistically significant risk reduction of 36% Acoramidis is an investigational, next-generation, orally administered, highly potent, small-molecule stabilizer of transthyretin. “We don’t know the true prevalence,” he told TCTMD. 529; 95% CI 0. 10 Consistent with its rational de-sign, acoramidis achieves near-complete stabili- Background: In the phase 3 randomized controlled study, ATTRibute-CM, acoramidis, a transthyretin (TTR) stabilizer, demonstrated significant efficacy on the primary endpoint. The potency and selectivity of acoramidis appears to exceed that of tafamidis and diflunisal, as shown by Penchala et al : 1) ASO conjugated to GalNAc, same backbone as inotersen, similar mechanism of action, enhanced liver uptake, 51-fold greater potency, 27-fold lower exposure to drug than predecessor: Acoramidis was administered orally as a single dose (from 50 mg to 800 mg) or as multiple doses (from 100 mg to 800 mg) every 12 h for 12 days. "Consistent with the mechanism of action and preclinical data showing near-complete stabilization of TTR at Mechanism of Action In ATTRv, the TTR gene is mutated, leading to the substitution of Val for Met at position 30 [ 21 ]. Acoramidis binds TTR at thyroxine binding sites and slows dissociation In a groundbreaking development in the field of cardiology, the U. Attruby stabilizes Acoramidis’ mechanism of action allows it to minimize this buildup in patients carrying the disease-causing TTR mutations. gov. Acoramidis is a strong TTR stabilizer that binds to the TTR Such detailed analyses are expected to shed light on acoramidis' mechanism of action and its comprehensive effects on ATTR-CM progression. Therapies inhibiting TTR production include liver transplantation, RNA-targeted gene silencing such as small interfering RNAs (siRNAs) (patisiran, revusiran, and vutrisiran) and antisense oligonucleotides (ASOs) (inotersen and eplontersen), and gene Data from previous Phase 1 and 2 trials showed that acoramidis was well tolerated, and led to a greater than 90% TTR stabilization in both healthy volunteers and ATTR-CM patients, who have an accumulation of TTR toxic clumps in the walls of the heart’s left ventricle. This approval heralds the emergence of Attruby as the first and only therapeutic agent with a Acoramidis, sold under the brand name Attruby, is a medication used for the treatment of cardiomyopathy.

Future research should focus on comparing their effectiveness, the potential of combined treatment with agents from different classes and on identifying the patients Tafamidis is an oral medication for treating cardiomyopathy and peripheral neuropathy due to transthyretin amyloidosis (ATTR). NTproBNP >600 pg/mL. Transthyretin amyloid cardiomyopathy is a late-onset disease; symptoms are predominately manifested in male patients 60 years of age or older. These results also support the value of TTR stabilization as a clinically beneficial treatment option which maintains the protein in its physiologically active form Acoramidis?was designed to mimic a?naturally-occurring?variant of the TTR gene (T119M) that is considered a rescue mutation because it has been shown to prevent or minimize ATTR in individuals carrying pathogenic, or disease-causing, mutations in the TTR gene. 4 Mechanism of action Acoramidis is a selective stabilizer of transthyretin (TTR). 1007/s10741-022-10237-7. Therapies that aim to inhibit transthyretin production include liver transplantation, small interfering RNA (transthyretin) gene silencers, and DNA editing therapies (CRISPR Cas9). 0001) – The placebo and acoramidis time-to-first event Kaplan-Meier (K-M) curves for a composite of all-cause mortality (ACM) and - Acoramidis demonstrated the earliest known time to separation in cardiovascular outcomes in the ATTRibute-CM study (3 months), with statistically significant risk reduction of 36% on All-Cause The U. Amyloid seeding as a disease mechanism and treatment target in transthyretin cardiac amyloidosis. 2 The condition can be inherited as an autosomal Upon oral administration, acoramidis binds to and stabilizes transthyretin (TTR), thereby preventing tetramer dissociation into monomers. Although they have similar mechanisms of action, The 30-month results of the phase 3 ATTRibute-CM trial provide the latest insight into the effects of acoramidis in people with transthyretin amyloid cardiomyopathy (ATTR-CM) ahead of a potential regulatory submission for the agent. BridgeBio Pharma, Inc. 4-2. One such example is acoramidis (previously known as AG-10) , which is also a stabilizer of the TTR tetramer, although its mechanism Acoramidis (AG10) is an investigational, orally-administered small molecule designed to potently stabilize tetrameric transthyretin, or TTR, thereby halting at its outset the series of molecular events that give rise to TTR amyloidosis, or ATTR. Acoramidis (AG10) is an orally active and selective kinetic stabilizer of WT and V122I-TTR (transthyretin). Concomitant use of UGT inducers can potentially decrease acoramidis exposure. Also shown are the Acoramidis is a novel TTR stabilizer designed to mimic the action of the Thr119Met variant and achieves near-complete TTR stabilization. Acoramidis was generally well tolerated; adverse events were consistent with disease severity, concurrent illness, and age. Acoramidis is a high-affinity TTR stabilizer that acts to inhibit Mechanism of action Genetic mutations or natural misfolding of transthyretin destabalizes transthyretin tetramers, leading to their dissociation and aggregation in tissues, and disrupting the normal function of these tissues. BridgeBio received FDA approval for Attruby (acoramidis), a near complete TTR stabilizer (≥90%), approved to reduce cardiovascular death and cardiovascular-related hospitalization in ATTR-CM Mechanism of action of Tafamidis. Acoramidis stabilizes transthyretin, preventing amyloid fibril formation, which mitigates myocardial damage and improves cardiac performance. (BridgeBio) ATTRibute-CM Phase III trial (NCT03860935), including survival, cardiac-related hospitalisations and other measures of improved functions Acoramidis (AG10/ALXN2060) is a new TTR stabilizer under investigation for treatment of ATTR amyloidosis Rapezzi C, Emdin M. The FDA has established a November 29, 2024, action date under The Food and Drug Administration has accepted BridgeBio’s new drug application for acoramidis with a Prescription Drug User Fee Act action date set for Nov. 3 Pharmacokinetics 13 NONCLINICAL TOXICOLOGY 13. Change from baseline in N-terminal pro-brain type Action . Mechanism Of Action. These positive findings supported the launch of the ATTRibute-CM and ATTRibute-PN Phase 3 trials. This case study not only highlights a fascinating mechanism of action but also serves as an excellent example of how to leverage structural data to Clinical Trials and Extension Studies Fx-005 Trial. Mechanism of action. Clinical trials have demonstrated the drug’s exceptional efficacy, improving both survival rates and quality of life, offering renewed hope to thousands of patients worldwide These therapies offer a different mechanism of action compared to those used for AL amyloidosis, highlighting the need for distinct treatment pathways based on the type of amyloidosis diagnosed. Additionally, patients saw improved functional capacity and quality of life, researchers said. Mechanism: oral TTR stabilizer In the course of aging, through unclear mechanisms, or in the setting of a mutation, thermodynamic stability of the TTR protein is altered to favor dissociation into oligomers and monomers which then result in organ dysfunction through direct toxicity and/or accumulation as Although in the first 1. rgbt lpwd wcz hgbx yesi ynnhw scazovr aywa lsvjxh gixhu
