Study Endpoints

Primary Endpoints

To evaluate the long-term safety and tolerability of acoramidis in participants with newly diagnosed ATTR-CM
The duration of study participation for the participants will be up to 5 years.

Proportion of participants with: treatment-emergent AEs and SAEs, AEs leading to treatment discontinuation, abnormal physical examination findings of clinical relevance, abnormal vital signs of clinical relevance, abnormal ECG parameters of clinical relevance, changes in clinical safety laboratory parameters of potential concern

Time to development of ATTR (ATTR-CM or ATTR-PN, whichever occurs first; centrally adjudicated)
Since randomization up to approximately 7 years or until the study is declared over

* ATTR-CM defined by biopsy or imaging-based diagnosis * ATTR-PN defined by new signs or symptoms and biopsy-based diagnosis

Incidence of treatment-emergent Adverse Events [Safety and Tolerability]
60 months

Incidence of each treatment-emergent adverse events measured over 60 Months or study completion

A Hierarchical Combination of All-Cause Mortality, Cumulative Frequency of CV-related Hospitalization, Change From Baseline in NT-proBNP and Change From Baseline in 6MWT at the Last Available Visit Where Both Subjects Had Non-missing Assessments.
Baseline up to Month 30

The endpoint was analyzed using Finkelstein-Schoenfeld method. The method combines all-cause mortality, cumulative frequency of CV-related hospitalizations, change from baseline in NT-proBNP and change from baseline in 6MWT in a hierarchical fashion. The method compares every participant with every other participant within strata, assigning a +1 to the "better" participant and a -1 to the "worse" participant and 0 if they are "tied". Participants who had heart transplantation or implantation of a cardiac mechanical assist device were handled in the same manner as death. 'Win' represents a participant doing better based on hierarchical comparison. The reported unit is the total percent of "wins" for each treatment group from performing such a hierarchical comparison across stratification factors in the study.

Frequently asked questions about acoramidis

What is Acoramidis used for?

Acoramidis is an investigational small molecule being developed for the treatment of transthyretin amyloidosis, including amyloid cardiomyopathy and related conditions. It is currently in Phase 3 clinical development and has not been approved by regulatory authorities.

What does Acoramidis target?

Acoramidis targets transthyretin (TTR), a protein that can misfold and accumulate as amyloid deposits in tissues, leading to cardiomyopathy and polyneuropathy. By stabilizing the TTR tetramer, it aims to prevent the formation of amyloid fibrils.

Who makes Acoramidis?

Acoramidis is being developed by BridgeBio Pharma, Inc., a biopharmaceutical company listed on NASDAQ under the ticker symbol BBIO. The company is conducting Phase 3 clinical trials to evaluate the drug's safety and efficacy.

What phase is Acoramidis in?

Acoramidis is in Phase 3 clinical development. It has completed a Phase 3 trial (NCT03860935) and a Phase 1 pharmacokinetic study, and is currently recruiting for another Phase 3 trial (NCT06563895) in asymptomatic carriers of a pathogenic TTR variant.

What clinical trials is Acoramidis in?

Acoramidis has been studied in three clinical trials. The completed Phase 3 trial NCT03860935 enrolled 632 participants with transthyretin amyloid cardiomyopathy. A Phase 1 study (NCT04769479) evaluated modified release formulations in healthy subjects. The ongoing Phase 3 trial NCT06563895 is recruiting 587 asymptomatic carriers of a pathogenic TTR variant.

Is Acoramidis the same as AG10?

Yes, Acoramidis is also known as AG10. The drug has been referred to by both names in clinical trial documentation and scientific literature, with AG10 being the earlier designation used in the Phase 3 trial title.
