Long-Term Survival with Daratumumab, Lenalidomide and Dexamethasone in Transplant-Ineligible Newly Diagnosed Multiple Myeloma Patients—A Survey from Two Italian Centers

Year: 2026

Type: article

Abstract: BACKGROUND: Multiple myeloma (MM) is a clonal plasma cell neoplasm representing the second most common hematological malignancy. The combination of daratumumab, lenalidomide and dexamethasone (D-Rd) was first approved by the EMA (European Medicines Agency) for the treatment of relapsed/refractory multiple myeloma (RRMM) patients, and was subsequently approved for first-line therapy, based on the results of POLLUX and MAIA trials, respectively. METHODS: In this survey, we retrospectively collected data from 96 consecutive transplant-ineligible newly diagnosed multiple myeloma (TIE-NDMM) patients treated with the D-Rd combination. RESULTS: The median age was 73 years; the median progression free survival (mPFS) and median overall survival (mOS) were not reached (NR); the overall response rate (ORR), defined as patients who obtained at least a partial response (PR), was 90%; 59% of patients achieved a very good partial response (VGPR) or better. A strong negative correlation was observed between treatment response and elevated beta-2-microglobulin levels. CONCLUSIONS: This study confirms the efficacy of the D-Rd combination as first-line therapy for TIE-NDMM patients, suggesting that achieving at least a PR-and particularly a VGPR-may represent a strong predictor of long-term remission and survival, even in the era of new combinations based on the use of quadruplets.
