24 mg/kg (maximum dose of 2500 mg) of NEOD001 administered once every 28 days.
NEOD001, is a humanized immunoglobulin G1 monoclonal antibody, which specifically targets misfolded light chain aggregates and amyloid deposits. NEOD001 is proposed for use to target the misfolded light chain protein in subjects with AL amyloidosis.
Placebo Comparator: Placebo
Placebo will be administered as a 250 mL bag of normal saline once every 28 days.
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 proteasome inhibitor-containing regimen, with the proteasome inhibitor 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.
