Prospective Study of Teclistamab in the Treatment of Systemic AL Amyloidosis

The treatment of amyloidosis should focus more on complete hematological response (CHR) and organ response rate. We hypothesize that teclistamab can deeply eliminate cloned plasma cells in AL patients, achieving a high proportion of complete hematological response. In clinical practice, if daratumumab, bortezomib, and venetoclax (for patients with t(11;14)）have been used, the outcome is poor. Also, CHR is correlated with better clinical outcomes. In clinical routine practice, we use teclistamab, a more effective treatment to eliminate clonal plasma cells. To further explore efficacy and safety, we designed this prospective study.
