Abstract
- BACKGROUND:While anti-BCMA chimeric antigen receptor T-cell therapy (CART) have proven safe and efficient in multiple myeloma (MM), its application to AL amyloidosis (AL), has been restricted due to the frailty of this population and rarity of disease. HBI0101 therapy is a novel anti-BCMA CART-based therapy developed at Hadassah Medical Center and Bar-Ilan University for MM treatment. In a phase Ia-b/2 study (NCT04720313), HBI0101 has demonstrated manageable safety with therapeutic efficacy in over 70 MM patients. Although BCMA targeting in AL has been questioned because of relatively low expression of this antigen on AL plasma cells (PC), we have previously reported that this level of expression is sufficient to enable PC eradication by HBI0101 CART ex vivo. Based on this observation, we have treated 9 AL patients in our study, which represent the largest cohort of AL treated with anti-BCMA CART reported so far.
