Efficacy and Feasibility of Dose/Schedule-Adjusted Rd-R Vs. Continuous Rd in Elderly and Intermediate-Fit Newly Diagnosed Multiple Myeloma Patients
Elderly patients with newly diagnosed multiple myeloma (NDMM) are highly heterogeneous and their outcome is influenced by many factors: beside age, also comorbidities, general physical fitness, and cognitive function play a crucial role. The IMWG frailty score combines age, functional status, and comorbidities, and it identifies fit, intermediate-fit and frail patients, with different risk of toxicity, treatment discontinuation, and mortality (Palumbo A et al. Blood 2015). Until now, evidence-based tailored treatments according to patients’ frailty are still lacking. Therefore, this phase III study investigated the efficacy and feasibility of dose/schedule-adjusted lenalidomide-dexamethasone therapy followed by lenalidomide maintenance (Rd-R) versus continuous lenalidomide-dexamethasone (Rd) in elderly, intermediate-fit NDMM patients.
This is the first prospective randomized phase III trial specifically designed for real-life intermediate-fit NDMM patients. A dose/schedule-adjusted Rd-R treatment was more feasible compared to full dose continuous Rd treatment in elderly intermediate-fit NDMM patients, with no negative impact but rather a comparable outcome. These results confirm the need for an appropriate definition of patient frailty, and pave the way to a frailty-adjusted treatment approach to better balance efficacy and safety in elderly NDMM patients.
