Conditions

Transthyretin Amyloid Cardiomyopathy (ATTR-CM)

Brief summary

Transthyretin amyloid cardiomyopathy (ATTR-CM) is a progressive heart disease caused by the buildup of an abnormal protein, called transthyretin (TTR), in the heart. This buildup can make it harder for the heart to pump blood and may lead to worsening symptoms over time. Acoramidis is a medicine approved for the treatment of adults with wild-type or hereditary (variant) ATTR-CM. While its benefits have been demonstrated in clinical trials, more information is needed about how it is used and how patients do in everyday medical practice. The MOSAIC-TTR study is an observational study in France. Participants will receive acoramidis as part of their usual medical care. No experimental treatments or additional medical procedures will be required. The study will collect information directly from participating hospitals and from the Healthcare European Amyloidosis Registry (HEAR; NCT05101304). The main goal of the study is to understand how patients' quality of life, daily functioning, and overall well-being change during the first 12 months of treatment with acoramidis, using questionnaires completed by the patients themselves. The study will also collect information about the characteristics of patients receiving acoramidis, how the medicine is used in routine clinical practice, and its safety and tolerability. The information collected will help improve the understanding of ATTR-CM and may help improve the care of people living with this condition.

Interventions

356 mg film-coated tablets. The recommended dose is 712 mg (two tables, 356 mg) orally twice daily, corresponding to a total daily dose of 1424 mg.
