Remarkable advancements have been made in the treatment outcomes of multiple myeloma (MM) patients; however, for frail elderly patients, these treatment outcomes are still insufficient. Elderly MM patients are increasing, as are their treatment regimens. There is a heightened demand to assess these patients in order to provide optimized treatments. While continuous treatment is more common for MM patients when compared to fixed-duration treatment, due to the risk of treatment interruption causing reduced survival rates, effectiveness and safety are essential. Treatment goals vary for each patient, but must preserve their quality of life (QOL). When planning treatments for these patients, frailty evaluation is increasingly emphasized as a stratification factor which helps develop accurate screening tools. Daratumumab (DARA) therapy, used globally, is not only effective in frail elderly MM patients, but also has QOL benefits. Proficiency in utilizing DARA regimens is potentially advantageous for patients not included in clinical trials, and innovative usage can further broaden its scope. The development of tools to accurately assess frailty and the establishment of optimal treatments for frail elderly MM patients are imperative. This review is an overview, challenging the frailty assessments for MM patients, re-examining the evidence for DARA regimens in frail elderly MM patients, and discussing potential areas for improvement.

Real-world studies permit inclusion of a more diverse patient population and provide more information on the effectiveness of treatments used in routine clinical practice. This prospective, multicenter, observational study investigated the effectiveness and safety of ixazomib plus lenalidomide and dexamethasone (IRd) in 295 patients with relapsed/refractory multiple myeloma (RRMM) in routine clinical practice in Japan. Patients had a median age of 74 years, 80.0% were aged ≥ 65 years, 42.0% had received ≥ 3 lines of prior treatment, and 28.5% were "frail" according to the International Myeloma Working Group frailty score. After a median follow-up of 25.0 months, median progression-free survival (PFS) was 15.3 (95% CI 12.4–19.5) months, while median overall survival was not reached. The overall response rate was 53.9%, and 31.5% of patients had a very good partial response or better. In the subgroup analysis, median PFS was better in patients with 1 versus 2 or ≥ 3 lines of prior treatment (29.0 vs 19.2 or 6.9 months) and paraprotein versus clinical relapse (16.0 vs 7.9 months), but median PFS was not notably affected by frailty score or age group. Dose adjustment was more frequent among patients aged > 75 years, especially early after IRd treatment initiation. Treatment-emergent adverse events (TEAEs) of any grade occurred in 84.4% of patients and 24.7% of patients discontinued treatment due to TEAEs; no new safety concerns were found. These findings suggest that oral IRd triplet regimen is an effective and tolerable treatment option for RRMM patients in real-world settings outside of clinical trials.
