Daratumumab for Patients With Light Chain Amyloidosis

Overview

This is a prospective, single-center study exploratory clinical trial, aim to exploring the efficacy and safety of daratumumab in patients with AL amyloidosis, patients were divided into three groups: one group received long-term treatment with daratumumab based regimen, and the other group received autologous stem cell transplantation after two standard treatment courses with daratumumab based regimen, and the third group consists of newly diagnosed stage IIIb AL amyloidosis patients who plan to receive DPD treatment. The purpose of this study is to observe the efficacy and safety of Daratumumab, in the treatment of newly diagnosed systemic AL amyloidosis.

This is a prospective, single-center study exploratory clinical trial, aim to exploring the efficacy and safety of daratumumab in patients with AL amyloidosis, patients were divided into three groups: one group received long-term treatment with daratumumab based regimen (group A) and the other group received autologous stem cell transplantation after two standard treatment courses with daratumumab based regimen (group B) , and the third group consists of newly diagnosed stage IIIb AL amyloidosis patients who plan to receive DPD treatment (group C). Participants with AL Amyloidosis will receive the drug daratumumab by IV infusion once weekly for two months, then every 2 weeks for four months, then once each month. Study treatment may continue until disease progression, unacceptable toxicity, or decision to withdraw from the trial. Disease evaluations will be performed every three months until disease progression. Group C were given Daratumumab (16mg/kg), dexamethasone (40mg) and pomalidomide. The usage of Daratumumab and dexamethasone is the same as group A and B. Patients received oral pomalidomide on days 1-21 of a 28-days cycle from cycle 1 to 6. The dose of pomalidomide is adjusted based on the patient's renal function and ECOG score.
