BACKGROUND: Daratumumab, a monoclonal antibody targeting CD38, has been approved for use with standard myeloma regimens. An evaluation of subcutaneous daratumumab combined with bortezomib, lenalidomide, and dexamethasone (VRd) for the treatment of transplantation-eligible patients with newly diagnosed multiple myeloma is needed. METHODS: In this phase 3 trial, we randomly assigned 709 transplantation-eligible patients with newly diagnosed multiple myeloma to receive either subcutaneous daratumumab combined with VRd induction and consolidation therapy and with lenalidomide maintenance therapy (D-VRd group) or VRd induction and consolidation therapy and lenalidomide maintenance therapy alone (VRd group). The primary end point was progression-free survival. Key secondary end points were a complete response or better and minimal residual disease (MRD)-negative status. RESULTS: At a median follow-up of 47.5 months, the risk of disease progression or death in the D-VRd group was lower than the risk in the VRd group. The estimated percentage of patients with progression-free survival at 48 months was 84.3% in the D-VRd group and 67.7% in the VRd group (hazard ratio for disease progression or death, 0.42; 95% confidence interval, 0.30 to 0.59; P<0.001); the P value crossed the prespecified stopping boundary (P = 0.0126). The percentage of patients with a complete response or better was higher in the D-VRd group than in the VRd group (87.9% vs. 70.1%, P<0.001), as was the percentage of patients with MRD-negative status (75.2% vs. 47.5%, P<0.001). Death occurred in 34 patients in the D-VRd group and 44 patients in the VRd group. Grade 3 or 4 adverse events occurred in most patients in both groups; the most common were neutropenia (62.1% with D-VRd and 51.0% with VRd) and thrombocytopenia (29.1% and 17.3%, respectively). Serious adverse events occurred in 57.0% of the patients in the D-VRd group and 49.3% of those in the VRd group. CONCLUSIONS: The addition of subcutaneous daratumumab to VRd induction and consolidation therapy and to lenalidomide maintenance therapy conferred a significant benefit with respect to progression-free survival among transplantation-eligible patients with newly diagnosed multiple myeloma.

BACKGROUND: In multiple myeloma (MM), improving our understanding of routine clinical practice and the effectiveness of agents outside of clinical trials is important. TOURMALINE-MM1 data resulted in approval of ixazomib for MM patients who have received ≥ 1 prior therapy. PATIENTS AND METHODS: UVEA-IXA comprised a retrospective chart review in the early access program, and a prospective 1-year follow-up period. Eligible patients had had a biochemical and/or symptomatic relapse after 1-3 prior lines of therapy; no anti-MM therapy for > 3 cycles at the start of ixazomib therapy; and an Eastern Cooperative Oncology Group performance score of 0-2. Lenalidomide- or proteasome inhibitor (PI)-refractory patients were ineligible. Primary endpoints were response and progression-free survival (PFS). RESULTS: Of 357 enrolled patients, 309 were evaluable; most patients received ixazomib alongside lenalidomide (98%) and dexamethasone (97%); 61% had received 2-3 prior lines of therapy. Median PFS was 15.6 months (95% confidence interval [CI]: 12.0-20.6) in all evaluable patients, and 19.6 (95% CI: 12.1-27.0) and 13.9 (95% CI: 10.1-18.1) months in patients who received 1 and ≥ 2 prior lines of therapy, respectively. The overall response rate was 67% in all evaluable patients, and 72% and 63%, respectively, in patients who received 1 and ≥ 2 prior lines of therapy. Median overall survival was 35.5 months. The ixazomib safety profile was consistent with previous reports. CONCLUSION: This study supports ixazomib-based therapy as an effective and tolerable treatment in the real-world. Outcomes were favorable in patients with 1 or ≥ 2 prior lines of therapy who were not lenalidomide- or PI-refractory.

Aim: We pooled data from three observational studies (INSIGHT MM, UVEA-IXA and REMIX) to investigate the real-world effectiveness of ixazomib-lenalidomide-dexamethasone (IRd) in relapsed/refractory myeloma. Materials & methods: INSIGHT MM was a prospective study conducted in countries across Europe, Asia and North/Latin America while UVEA-IXA and REMIX were multicenter, retrospective/prospective studies conducted in Europe. Patients who had received IRd as ≥2nd line of therapy were analyzed. Primary outcomes were time-to-next treatment (TTNT) and progression-free survival (PFS). Results: Overall, 564 patients were included (median follow-up: 18.5 months). Median TTNT and PFS were 18.4 and 19.9 months; both outcomes were numerically longer for earlier versus later lines. Median treatment duration was 14.0 months. Overall response rate was 64.6%. No new safety concerns were noted. Conclusion: The effectiveness of IRd in routine practice appears similar to the efficacy observed in TOURMALINE-MM1. IRd benefit in earlier versus later lines was consistent with previous reports.

Východiska: Volba léčby u pacientů s agresivním mnohočetným myelomem (MM), rezistentním na několik léčebných modalit, je v podmínkách reálné klinické praxe velmi obtížná. Ixazomib je perorální inhibitor proteazomu druhé generace. V kombinaci s lenalidomidem a dexametazonem je účinným a nízce toxickým léčebným režimem pro pacienty s relabovaným či refrakterním MM. Pozorování: Prezentované kazuistiky dvou pacientů s agresivním průběhem MM demonstrují překvapivou účinnost tohoto režimu. Závěr: Opakovaná léčba kombinací inhibitorů proteazomu (ixazomib) a imunomodulačních léků (lenalidomid) může u některých pacientů vést k výraznému klinickému benefitu a měla by být zvážena i u pacientů s vyčerpanými léčebnými možnostmi.
Background: The treatment of aggressive multiple myeloma (MM) patients, resistant to several treatment modalities, is very difficult in the real-world-evidence conditions. Ixazomib is a second-generation oral proteasome inhibitor. In combination with lenalidomide and dexamethasone, it is an effective and low-toxic treatment regimen for patients with relapsed or refractory MM. Observation: The presented case reports of two patients with an aggressive course of MM demonstrate the surprising effectiveness of this regimen. Conclusion: Repeated treatment with a combination of proteasome inhibitors (ixazomib) and immunomodulatory drugs (lenalidomide) may lead to significant clinical benefit in some patients and should be considered even in end-stage disease patients.

We performed real world evidence (RWE) analysis of daratumumab, lenalidomide and dexamethasone (Dara-Rd) versus lenalidomide and dexamethasone (Rd) treatment in relapsed/refractory multiple myeloma patients (RRMM). In total, 240 RRMM patients were treated with Dara-Rd from 2016 to 2022 outside of clinical trials in all major Czech hematology centers. As a reference, 531 RRMM patients treated with Rd were evaluated. Patients' data were recorded in the Czech Registry of Monoclonal Gammopathies (RMG). Partial response (PR) or better response (ORR) was achieved in significantly more patients in Dara-Rd than in Rd group (91.2% vs. 69.9%; p < 0.001). The median progression free survival (PFS) was 26.9 months in the Dara-Rd and 12.8 months in the Rd group (p < 0.001). Median overall survival (OS) was not reached in the Dara-Rd compared to 27.2 months in the Rd group (p = 0.023). In patients with 1-3 previous treatment lines, there was significant PFS benefit of Dara-Rd compared to Rd (median PFS not reached vs. 13.2 months; p < 0.001). In patients with > 3 previous treatment lines, there was no significant PFS benefit of Dara-Rd treatment (7.8 months vs. 9.9 months; p = 0.874), similarly in patients refractory to PI + IMIDs (11.5 months vs. 9.2 months; p = 0.376). In RWE conditions, the median PFS in RRMM patients treated with Dara-Rd is shorter when compared to clinical trials. In heavily pretreated RRMM patients, efficacy of Dara-Rd treatment is limited; best possible outcomes of Dara-Rd are achieved in minimally pretreated patients.

Anti-CD19 immunotherapy tafasitamab is used in combination with lenalidomide in patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) who are ineligible for autologous stem cell transplant. Open-label, phase 1b, First-MIND study assessed safety and preliminary efficacy of tafasitamab + R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) ± lenalidomide as first-line therapy in patients with DLBCL. From December 2019 to August 2020, 83 adults with untreated DLBCL (International Prognostic Index 2-5) were screened and 66 were randomly assigned (33 per arm) to R-CHOP-tafasitamab (arm T) or R-CHOP-tafasitamab-lenalidomide (arm T/L) for 6 cycles. Primary end point was safety; secondary end points included end-of-treatment (EoT) overall response rate (ORR) and complete response (CR) rate. All patients had ≥1 treatment-emergent adverse event, mostly grade 1 or 2. Grade ≥3 neutropenia and thrombocytopenia occurred, respectively, in 57.6% and 12.1% (arm T) and 84.8% and 36.4% (arm T/L) of patients. Nonhematologic toxicities occurred at similar rates among arms. R-CHOP mean relative dose intensity was ≥89% in both arms. EoT ORR was 75.8% (CR 72.7%) in arm T and 81.8% (CR 66.7%) in arm T/L; best ORR across visits was 90.0% and 93.9%. Eighteen-month duration of response and of CR rates were 72.7% and 74.5% (arm T) and 78.7% and 86.5% (arm T/L); 24-month progression-free and overall survival rates were 72.7% and 90.3% (arm T) and 76.8% and 93.8% (arm T/L). Manageable safety and promising signals of efficacy were observed in both arms. Potential benefit of adding tafasitamab + lenalidomide to R-CHOP is being investigated in phase 3 frontMIND (NCT04824092). This study is registered at www.clinicaltrials.gov as #NCT04134936.
