About

Frailty is dynamic and confers poor outcomes in elderly patients with newly diagnosed multiple myeloma (NDMM), mainly because of the high prevalence of treatment discontinuation due to intolerability. We designed a multi-center prospective study (DynaFiT) based on our real-life practice to evaluate the feasibility and benefits of a dynamic frailty-tailored therapy in elderly patients with different fitness/frailty statuses.

Since Dara-based treatment have recently become the new standard regimens, in this amendment of the study, daratumumab added to VRd is recommended as induction therapy regimen.

Full description

Older patients with MM represent a heterogeneous population with different fitness/frailty statuses. Unlike fit patients who can benefit from intensive therapies due to their endurance, frail patients are often susceptible to treatment-related toxicity, leading to treatment discontinuation and poor outcomes. More importantly, frailty can diminish the prognostic impact of disease-related factors over disease trajectory. Thus, it is of utmost importance to determine the fitness/frailty status for treatment decision-making that carefully balances efficacy and safety in this vulnerable population. However, geriatric assessment is often conducted at diagnosis in clinical practice. Although baseline frailty status, as a static risk factor, is significantly associated with OS, its predictive ability decreases over time. Of note, emerging evidence indicates that the fitness/frailty status is highly dynamic because of age increase, disease trajectory, and treatment, raising the notion that frailty-tailored therapy should be designed based on the baseline fitness/frailty status and also according to its longitudinal changes during the treatment course. Thus, current frailty status better predicts OS.

To improve outcomes in elderly patients, this study was designed to investigate an entirely novel therapeutic strategy, the dynamic frailty-tailored therapy, in elderly MM patients with different fitness/frailty statuses.
