Daratumumab Plus Bortezomib and Dexamethasone in Newly Diagnosed Systemic Light Chain Amyloidosis.

Light chain amyloidosis (AL) is a plasma cell dyscrasia characterized by organ dysfunction, morbidity, and early mortality. Daratumumab in combination with cyclophosphamide, bortezomib, and dexamethasone is now standard frontline AL therapy; however, not all patients are candidates for this intensive regimen. Given the potency of Daratumumab, we evaluated an alternative frontline regimen: daratumumab, bortezomib, and limited-duration dexamethasone (Dara-Vd).
