Carfilzomib is an effective upfront treatment in AL amyloidosis patients with peripheral and autonomic neuropathy

Bortezomib is standard treatment in AL amyloidosis (AL), but is contraindicated in patients with significant neuropathy. Carfilzomib, a second-generation proteosomal inhibitor, results in a lower incidence of neuropathy than bortezomib, but data in AL is scant. We report a cohort of five AL patients treated with upfront carfilzomib. All had cardiac, peripheral and autonomic neuropathy at presentation. All achieved at least a very good partial haematological response. There was no worsening in cardiac function, peripheral or autonomic neuropathy. Carfilzomib is an effective upfront treatment option in AL patients with peripheral and/or autonomic neuropathy (without severe cardiac or renal involvement).
