This single-centre retrospective observational study analysed the efficacy of retreatment with immunomodulatory agents (IMiDs) and proteasome inhibitors (PIs) after treatment with daratumumab monotherapy in patients with relapsed and/or refractory multiple myeloma (RRMM). In total 55 patients were treated with daratumumab monotherapy between 2010 and 2017. From this group 29 (53%) IMiD-refractory patients were retreated with an IMiD after daratumumab and 6 (11%) PI-refractory patients were retreated with a PI-based regimen. For the IMiD-refractory patients the overall response rate (ORR) was 52% (15/29 patients, partial response or better) upon IMiD retreatment, whereas the ORR to PI retreatment was 67% (4/6 patients) in the PI-refractory group. The immunomodulatory effects of daratumumab may play a role in these high response rates in previously refractory patients. Due to the >6 month-long persistence of daratumumab in the plasma the subsequent therapies can effectively be considered as combination therapy. Furthermore, the excellent tolerability of daratumumab treatment may enable patients to recover from prior lines of treatment and receive full dosing of subsequent therapies. In conclusion, a high proportion of RRMM patients benefitted from retreatment with IMiDs and PIs after daratumumab treatment. These retreatment options should therefore be explored in RRMM patients progressing on daratumumab monotherapy.

Purpose: Daratumumab is a novel, first-in-class monoclonal antibody approved for use as monotherapy and in combination with other treatments for patients with multiple myeloma (MM). The aim of this observational study was to evaluate the effectiveness and safety of daratumumab in real-world clinical practice.
Materials And Methods: This observational multicenter study collected data from patients with MM treated in Korea between June 1, 2018, and February 28, 2022.

Background: Daratumumab, an anti-CD38 monoclonal antibody, has been approved for the treatment of multiple myeloma. Data are needed regarding the use of daratumumab for high-risk smoldering multiple myeloma, a precursor disease of active multiple myeloma for which no treatments have been approved.
Methods: In this phase 3 trial, we randomly assigned patients with high-risk smoldering multiple myeloma to receive either subcutaneous daratumumab monotherapy or active monitoring.

Although bispecific T-cell engager (BiTE) is a promising treatment for relapsed/refractory multiple myeloma (RRMM), it needs to be evaluated in a real-world setting. This study aimed to evaluate the efficacy and safety of BiTEs compared with a synthetic standard of care (SOC). From a multicenter registry database of 474 patients with RRMM who received third- or more advanced-line treatments between January 2021 and October 2023, 1:1 propensity score-matched BiTE cohort (n = 71) and SOC cohort (n = 71) were established.
