About this trial

Achievement of complete hematologic response (CHR) is vital for systemic AL amyloidosis. Currently, the CHR rate of daratumumab, bortezomib, and dexamethasone (DBD) is close to 60%. Considering that Bcl-2 inhibitor is effective for AL amyloidosis with t(11; 14) and the median hematologic onset time of DBD is 7 days. We design a a prospective study on AL amyloidosis with t(11; 14). All patients receive DBD at the beginning. Patient will receive DBD for at least 6 cycles if achieve rapid hematologic response at day 7, while other patients will receive daratumumab, venetoclax and dexamethasone.
