Isa-VRdlite for of Frail and/or Much Older Patients With High Risk Newly Diagnosed Multiple Myeloma Base on Circulating Plasma Cells

Newly diagnosed transplant-ineligible multiple myeloma patients (high-risk defined by GA score and circulating plasma cells (CPCs) ≥0.07%) will receive isatuximab plus reduced-intensity VRD (VRDlite) induction therapy, as detailed below: Isatuximab (Isa) 10 mg/kg per administration. Cycle 1: administered on Days 1, 8, 15 and 22. From Cycle 2 onwards: once every two weeks (Days 1 and 15). Dose reduction of isatuximab is prohibited throughout treatment until disease progression, intolerable toxicity, or completion of scheduled therapy. Reduced-intensity VRD (VRDlite) Bortezomib (V): 1.0 mg/m² subcutaneously on Days 1, 8, 15 and 22 of each cycle. Lenalidomide (R): 10 mg orally once daily on Days 1-21 of each cycle; individualized dose reduction shall be performed for patients with renal impairment according to estimated glomerular filtration rate (eGFR).
