A Study to Evaluate the Effectiveness and Safety of CAEL-101 in Patients With Mayo Stage IIIb AL Amyloidosis

Titre officiel

A Phase 3, Double-Blind, Multicentre Study to Evaluate the Efficacy and Safety of CAEL-101 and Plasma Cell Dyscrasia Treatment Versus Placebo and Plasma Cell Dyscrasia Treatment in Plasma Cell Dyscrasia Treatment Naïve Patients With Mayo Stage IIIb AL Amyloidosis

Sommaire:

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 if CAEL-101 improves the overall survival in Patients with cardiac AL Amyloidosis.

Description de l'essai

Primary Outcome:

  • Time from the first dose of study drug until death or end of study.
  • Number of patients with treatment emergent adverse events as assessed by CTCAE v5.0
Secondary Outcome:
  • Change in distance walked (in meters) during a six-minute walk test
  • Quality of Life (QOL) by the Kansas City Cardiomyopathy Questionnaire-Overall Score (KCCQ-OS)
  • Quality of Life (QOL) by the Short Form-36 (SF-36) v2 Physical Component Score (PCS)
  • Cardiac Improvement by Global Longitudinal Strain (GLS%)
This is a double-blind, randomized, multicentre international Phase 3 study of CAEL-101 combined with the standard of care (SoC) for plasma cell dyscrasia (PCD) versus placebo combined with standard of care PCD treatment in patients with Mayo stage IIIb AL amyloidosis that have not received prior treatment. The minimum planned treatment time for each patient will be at least 50 weeks or until the patient's death. It is planned that all patients will continue their double-blind treatment until the last patient completes at least 50 weeks of treatment. Approximately 111 patients will be enrolled using a 2:1 randomization ratio of CAEL-101: placebo and will involve approximately 70 investigator sites. The primary objective of this study is to assess the effects of CAEL-101 versus placebo on all-cause mortality.
