Abstract

Introduction
Daratumumab, an anti-CD38 monoclonal antibody, has recently been approved by FDA and EMA for first-line treatment of systemic light chain (AL) amyloidosis in combination with cyclophosphamide, bortezomib and dexamethasone (Dara-CyBorD). In this case series we share our experience in treatment of AL amyloidosis with Dara-CyBorD.

Case series
From August 2022 to January 2024 overall 10 patients (6 female) with newly diagnosed AL amyloidosis received treatment with the Dara-CyBorD regimen. Age ranged from 44 to 74 years at the beginning of treatment (median 57 [IQR 53-62]). One patient was diagnosed in Mayo2004/European stage I, three patients in stages II, IIIA, IIIB each. Two patients (both stage IIIB) died due to complications associated with amyloid-related organ damage; 8 patients continue treatment. All patients achieved at least a very good partial hematologic response after the first cycle of Dara-CyBorD, 7 patients achieved complete response. In 5 cases, sustained organ response was achieved (cardiac in patients #1, #2, #5, #7; renal - #7, #9). Tolerability was acceptable, no serious adverse events were registered.

Conclusion
Daratumumab in combination with CyBorD has been demonstrated as a well-tolerated and effective therapy regimen for newly diagnosed AL amyloidosis. Rapid satisfactory hematologic responses were seen in all cases; sustained cardiac response was seen in select individuals regardless of initial disease stage.
