MMY3021 (AURIGA) Study
Last Updated: 09/23/2025
SUMMARY
- DARZALEX FASPRO for subcutaneous (SC) use is not approved by the regulatory agencies for use in combination with lenalidomide following autologous stem cell transplant (ASCT). Janssen does not recommend the use of DARZALEX FASPRO in a manner that is inconsistent with the approved labeling.
- AURIGA (MMY3021) is an ongoing, open-label, active-controlled, multicenter, randomized phase 3 study evaluating the conversion rate to minimal residual disease (MRD)-negativity after maintenance treatment with DARZALEX FASPRO in combination with lenalidomide (D-R) vs lenalidomide (R) alone in patients with newly diagnosed multiple myeloma (NDMM) who are anti-cluster of differentiation (CD) 38 naïve, have
a very good partial response or better (≥VGPR), and are MRD-positive following ASCT after standard-of-care induction/consolidation. A total of 200 patients were randomized.1 , 2 - Badros et al (2024)2-
4 reported primary results from the phase 3 AURIGA study at a median follow up of 32.3 months. The MRD-negativity (10-5 ) conversion rate by 12 months from initiation of maintenance, was significantly higher for D-R vs R (50.5% vs 18.8%; odds ratio [OR], 4.51; 95% confidence interval [CI], 2.37-8.57; P<0.0001). Similarly, the MRD-negativity (10-6 ) conversion rate by 12 months from initiation of maintenance was higher with D-R vs R (23.2% vs 5.0%; OR, 5.97; 95% CI, 2.15-16.58; P=0.0002). At the median follow up, the D-R vs R arm showed a higher overall MRD-negativity conversion rate (10-5 sensitivity, 60.6% vs 27.7%;
10-6 sensitivity, 36.4% vs 12.9%) and a higher complete response or better (≥CR) rate (75.8% vs 61.4%). Progression-free survival (PFS) favored D-R vs R with 47% reduction in the risk of disease progression or death (hazard ratio [HR], 0.53; 95% CI, 0.29-0.97). At 30 months, the estimated PFS was 82.7% vs 66.4% and the estimated overall survival (OS) for the intention-to-treat (ITT) population was 94.6% vs 91.0% in the D-R vs R arm, respectively. Slightly higher occurrence rates of grade 3/4 cytopenias (54.2% vs 46.9%) and infections (18.8% vs 13.3%) were observed with D-R vs R. Serious adverse events (AEs) were reported in 30.2% vs 22.4% of patients in the D-R vs R arm, respectively. - Anderson Jr et al (2025)5
presented updated efficacy and safety results from the phase 3 AURIGA study 24 months from the start of maintenance therapy, with a median follow-up of 40.3 months. The MRD-negativity (10-5) conversion rate was significantly higher for D-R vs R (60.6% vs 28.7%; OR, 3.92; 95% CI, 2.16-7.14; P<0.0001). Similarly, the MRD-negativity (10-6) conversion rate was higher with D-R vs R (36.4% vs 13.9%; OR, 3.59; 95% CI, 1.78-7.23; P=0.0003). Serious treatment-emergent adverse events (TEAEs) were reported in 31.3% vs 25.5% of patients in the D-R vs R arm, respectively. No new safety concerns were identified with the addition of DARZALEX FASPRO to R maintenance.
- Badros et al (2024)2-
- Foster et al (2024)6
presented a post hoc analysis of the phase 3 AURIGA study regarding clinically relevant subgroups at a median follow-up of 32.3 months. The clinically relevant subgroups included elderly and black patients, patients with high-risk disease per International Staging System (ISS) disease staging, and patients with high cytogenetic risk per standard, revised, and International Myeloma Society (IMS) 2024 high-risk criteria. The subgroup analyses of MRD-negativity (10-5 sensitivity) conversion rates by 12 months of maintenance appeared to consistently favor D-R vs R maintenance alone regardless of age, race, ISS disease stage, or response upon study entry. D-R vs R maintenance improved MRD-negativity (10-5 sensitivity) conversion rates by 12 months in patients with ultra-high-risk disease, standard-risk disease, and patients with modified IMS 2024 high-risk disease. D-R vs R maintenance showed a PFS benefit across various definitions of high cytogenetic risk, in addition to patients with standard-risk disease and regardless of the number of high-risk cytogenetic abnormalities (HRCAs). D-R vs R maintenance improved PFS among patients with gain/amp(1q21), irrespective of other HRCAs (HR, 0.46; 95% CI, 0.13-1.59). No additional safety concerns were observed in patients aged ≥65 years or in Black patients. D-R maintenance did not increase grade 3/4 infection or cytopenia rates in patients ≥65 years of age.

Efficacy
The MRD status and response rates in the ITT population are summarized in Table: Summary of MRD Status and Response Rates in the ITT Population.2,3 - The MRD-negativity (10-5 sensitivity) conversion rate by 12 months from initiation of maintenance (primary endpoint), was significantly higher for D-R vs R (50.5% vs 18.8%; OR, 4.51; 95% CI, 2.37-8.57; P<0.0001).
- The D-R arm yielded approximately 2.5 times greater sustained MRD-negativity
(10-5 sensitivity) rates at ≥6 months (35.4% vs 13.9%) and relatively higher sustained MRD-negativity (10-5 sensitivity) rates at ≥12 months (17.2% vs 5.0%) than the R arm.
- Subgroup analyses of MRD-negativity (10-5 sensitivity) conversion rates at 12 months appeared to consistently favor D-R over R across most clinically relevant subgroups, including patients with a standard or high cytogenetic risk and older patients; the results are summarized in Table: Subgroup Analysis of MRD-Negativity (10-5) Conversion Rate From Baseline to 12 Months of Maintenance Treatment in the ITT Population.2
- At a median follow-up of 32.3 months, treatment with D-R vs R maintenance yielded a greater improvement in PFS, with 47% reduction in the risk of disease progression or death (HR, 0.53; 95% CI, 0.29-0.97; nominal P=0.0361).2,3
- At 30 months, the estimated PFS rate in the D-R vs R arm was 82.7%
(95% CI, 72.8-89.3) vs 66.4% (95% CI, 54.0-76.2), respectively.2 At 30 months, the estimated OS in the D-R vs R arm of the ITT population was
94.6% vs 91.0% (HR, 0.50; 95% CI, 0.17-1.50; P=0.2081), respectively.2,4

The stratification factor was the baseline cytogenetic risk per investigator assessment (high vs standard/unknown) as used for randomization. An OR of >1 indicates an advantage for the D-R arm. bAll parameters, except ≥CR were assessed using Fisher’s exact test. ≥CR rates were accessed using Cochran-Mantel-Haenszel chi-squared test. cAt a median follow-up of 32.3 months. dSustained MRD-negativity at ≥6 months and ≥12 months is defined as an MRD-negative status (at 10-5 sensitivity threshold) in 2 bone marrow aspirate assessments spaced a minimum of 6 months and 12 months apart, respectively, without any assessment showing an MRD-positive status in between the assessments. | ||||

Efficacy
- The MRD status and conversion rates in the ITT population are summarized in Table: Summary of MRD Status and Conversion Rates in the ITT Population.5
- The overall MRD-negativity (10-5 sensitivity) conversion rate was significantly higher for D-R vs R (60.6% vs 28.7%; OR, 3.92; 95% CI, 2.16-7.14; P<0.0001).
- The D-R arm yielded a more than 2 times greater sustained MRD-negativity
(10-5 sensitivity) rates at ≥6-months (42.4% vs 17.8%) and at ≥12 months (29.3% vs 7.9%) than the R arm.
- Subgroup analyses of MRD-negativity (10-5 sensitivity) conversion rates consistently favored D-R over R in all patient subgroups, regardless of age and race; the results are summarized in Table: Subgroup Analysis of MRD-Negativity (10-5) Conversion Rates in Patient Subgroups.5

- The median duration of therapy was 23.7 months (D-R, 29.3 vs R, 18.9 months) for White patients and 25.4 months (D-R, 28.3; R, 25.4 months) for Black patients. The safety results for patients with ≥1 TEAE based on race is summarized in Table: Safety Results for Patients With ≥1 TEAE Based on Race.
- D-R maintenance did not increase grade 3/4 infection or cytopenia rates in patients ≥65 years of age.6
