Overview
Brief Summary
This is a multi-center, international, randomized, double-blind, placebo-controlled, two-arm efficacy and safety study in subjects newly diagnosed with AL amyloidosis. Subjects will remain on-study until study completion, which will occur when all primary endpoint events (all-cause mortality or cardiac hospitalizations) have been reached.
Detailed Description
This is a multi-center, international, randomized, double-blind, placebo-controlled, two-arm efficacy and safety study in subjects newly diagnosed with AL amyloidosis. Approximately 236 subjects will be enrolled in \~60 centers, with approximately 118 subjects per arm. This is an event driven trial, therefore subjects will remain on-study until study completion, which will occur when all primary endpoint events (all-cause mortality or cardiac hospitalizations) have been reached. All subjects who discontinue will be followed until the last event is adjudicated. The estimated overall study duration is approximately 42 months, including the enrollment and treatment periods Study drug will be administered once every 28 days as a 60-120 minute IV infusion. First-line chemotherapy must be a bortezomib-containing regimen, with bortezomib administered weekly. The number of cycles of first-line chemotherapy that are administered are at the discretion of the Investigator, and subsequent chemotherapy regimens may be prescribed as per standard of care at the Investigator's discretion. An independent Data Monitoring Committee (DMC) will review data on a regular basis.
