Isa-VRdlite for of Frail and/or Much Older Patients With High Risk Newly Diagnosed Multiple Myeloma Base on Circulating Plasma Cells
Sponsor: The Affiliated People's Hospital of Ningbo University
Summary
To evaluate the overall response rate, safety, and the 12-cycle clearance rate of circulating plasma cells (CPCs) in patients with newly diagnosed transplant-ineligible multiple myeloma stratified as high-risk based on circulating plasma cell assessment treated with isatuximab combined with reduced-dose VRD regimen

Isatuximab
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): 1.3 mg/m², subcutaneous injection, Days 1, 8, 15, 22 per cycle. This administration route reduces the incidence of peripheral neuropathy. Lenalidomide (R): 15 mg once daily orally, Days 1-21 per cycle. Dose should be further individualized and reduced for patients with renal insufficiency according to eGFR
