摘要
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 IIIb AL amyloidosis.
A Hierarchical Combination of Time to All-cause Mortality and Frequency of Cardiovascular Hospitalizations (CVHs) Analyzed by Win Ratio
Day 1 through end of the participant's PETP (Participants were enrolled on a rolling basis. Therefore, the primary analysis for the study was conducted 18-47 months after the study randomization.) · win ratio
| Combined CAEL-101 + Plasma Cell Dyscrasia Treatment and Placebo + Plasma Cell Dyscrasia Treatment | 0.95 win ratio |

| Combined CAEL-101 + Plasma Cell Dyscrasia Treatment and Placebo + Plasma Cell Dyscrasia Treatment | 1.57 win ratio |

| Combined CAEL-101 + Plasma Cell Dyscrasia Treatment and Placebo + Plasma Cell Dyscrasia Treatment | 0.71 win ratio |
