Study Summary

AL (or light chain) amyloidosis begins in the bone marrow where abnormal proteins misfold and create free light chains that cannot be broken down. These free light chains bind together to form amyloid fibrils that build up in the extracellular space of organs, affecting the kidneys, heart, liver, spleen, nervous system and digestive tract. The primary purpose of this study is to determine whether CAEL-101, a monoclonal antibody that removes AL amyloid deposits from tissues and organs, improves overall survival, reduces cardiovascular related hospitalizations and it is safe and well tolerated in patients with stage IIIa AL amyloidosis.

Primary Outcome

Time to all-cause mortality was defined as the number of weeks from the date of randomization to the date of death if it is on or before the end of PETP. Participants alive at the end of PETP (LPI+18 months) were censored at their last known alive date recorded within the PETP. CVHs were events adjudicated and confirmed as such by the Clinical Event Adjudication Committee (CEAC). Hypothesis testing with the Finkelstein-Schoenfeld test and treatment effect estimation with the win-ratio method bas
