Cardiac Magnetic Resonance and Echocardiography Study With Acoramidis (ASCEND-ATTR)

Detaljeret beskrivelse
Study AG10-404 is an open-label study to investigate the long-term effects of acoramidis on cardiac functional and structural improvement, and the effects on cardiac amyloid burden in participants with ATTR-CM using two types of imaging, cardiac MRI and echocardiograms to track changes in heart structure and amyloid buildup over time.
Up to approximately 150 participants (ages 18-80) will be enrolled. Participants will receive study drug (712mg equivalent to 800mg of acoramidis hydrochloride) orally twice daily from Day 1 through Month 36. The study duration for an individual participant is approximately 38 months, including up to 45 days for screening, 36 months for open-label treatment and 1 month follow-up after the last dose of study drug. In-clinic visits will occur at Day 1, Day 28, Month 6, and every 6 months up to Month 36. Phone visits will occur at Month 3 and every 6 months thereafter up to Month 33. Participants will be followed throughout their participation in this study and for 30 days (+7 days) after the last dose of study drug.
