Current frontline treatment with lenalidomide and dexamethasone is unable to produce durable responses in patients with newly diagnosed multiple myeloma (NDMM). There is a need for more effective agents at the time of diagnosis for patients who are ineligible for autologous stem cell transplant or high-dose chemotherapy, who have limited treatment options if relapse occurs.
The primary analysis of the phase III MAIA trial (NCT02252172) demonstrated improved survival outcomes when daratumumab, an anti-CD38 monoclonal antibody, was combined with lenalidomide and dexamethasone (Dara-Rd) as a frontline therapy compared with Rd alone. However, longer follow-up was needed to see if the advantage in progression-free survival (PFS) also translated into a prolonged overall survival (OS).1,2 At the 26th Congress of the European Hematology Association (EHA), Thierry Falcon presented updated efficacy and safety results from this comparative study after almost 5 years of median follow-up.1 We summarize the key findings below.
Patient characteristics (n = 732) are summarized in Table 1.

Overall, these data provide strong support for the use of daratumumab as part of frontline therapy for NDMM in elderly patients or those with comorbidities who are ineligible for transplant or high-dose chemotherapy. Importantly, Falcon highlighted a clinically significant improvement in 5-year OS with Dara-Rd versus Rd alone, with a 32% reduction in the risk of death. The primary endpoint was also met, with a significant benefit for PFS with the addition of daratumumab maintained from the primary analysis. Finally, a favorable safety profile with similar, lower rates of AEs between both treatments was observed after longer follow-up.
