Trial Summary

What is the purpose of this trial?

This phase III trial studies how well lenalidomide and dexamethasone works with or without daratumumab in treating patients with high-risk smoldering myeloma. Drugs used in chemotherapy, such as lenalidomide and dexamethasone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as daratumumab, may induce changes in the body's immune system and may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide and dexamethasone with daratumumab may work better in treating patients with smoldering myeloma.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, you cannot have had prior or concurrent systemic or radiation therapy for myeloma, and certain medications like erythropoietin and high-dose glucocorticosteroids are not allowed during the study.

What data supports the effectiveness of the drug combination of Lenalidomide, Dexamethasone, and Daratumumab for treating multiple myeloma?

Research shows that adding Daratumumab to Lenalidomide and Dexamethasone significantly improves outcomes for multiple myeloma patients. In studies, this combination reduced the risk of disease progression or death and increased the number of patients who responded well to treatment compared to using Lenalidomide and Dexamethasone alone. ^{1 2 3 4 5}

Is the combination of Lenalidomide, Dexamethasone, and Daratumumab safe for treating multiple myeloma?

The combination of Lenalidomide, Dexamethasone, and Daratumumab has been generally well-tolerated in multiple myeloma patients, with common side effects including low blood cell counts (neutropenia, thrombocytopenia, anemia), nerve damage (peripheral sensory neuropathy), and infections. Infusion-related reactions were mostly mild and occurred during the first infusion. ^{1 3 4 5 6}

How does the drug combination of Lenalidomide, Dexamethasone, and Daratumumab differ from other treatments for multiple myeloma?

The combination of Lenalidomide, Dexamethasone, and Daratumumab is unique because it includes Daratumumab, a monoclonal antibody that targets CD38 on myeloma cells, enhancing the immune system's ability to kill these cells. This combination has shown to significantly improve progression-free survival and overall response rates compared to Lenalidomide and Dexamethasone alone, making it a more effective option for patients with relapsed or refractory multiple myeloma. ^{1 3 4 6 7}

Inclusion Criteria

I am not pregnant, will test regularly, and use birth control during treatment.

I must have a specific urine test monthly if my initial results show a high protein level.

I was diagnosed with a high-risk form of smoldering multiple myeloma less than a year ago and I don't have symptoms.

Treatment Details

Interventions

• Daratumumab (Immunotherapy)
• Dexamethasone (Corticosteroid)
• Lenalidomide (Immunomodulator)

Trial Overview The study tests lenalidomide and dexamethasone with or without daratumumab in patients with high-risk smoldering myeloma. It aims to see if adding daratumumab improves outcomes by altering the immune system's response to tumor cells.

Participant Groups

Group I: Arm II (lenalidomide, dexamethasone) Experimental Treatment 4 Interventions

Patients receive lenalidomide PO daily on days 1-21 and dexamethasone PO on days 1, 8, 15, and 22 of courses 1-12. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity.

Group II: Arm I (daratumumab, lenalidomide, dexamethasone) Experimental Treatment 4 Interventions

Patients receive daratumumab IV on days 1, 8, 15, and 22 of courses 1-2, days 1 and 15 of courses 3-6, and day 1 of courses 7-24. Patients also receive lenalidomide PO daily on days 1-21 and dexamethasone PO on days 1, 8, 15, and 22 in courses 1-12. Treatment repeats every 28 days for up to 24 courses in the absence of disease progression or unacceptable toxicity.

Findings from Research

In the POLLUX study, after 25.4 months of follow-up, the combination of daratumumab with lenalidomide and dexamethasone significantly improved progression-free survival in patients with relapsed/refractory multiple myeloma, with a hazard ratio of 0.41 compared to lenalidomide/dexamethasone alone.

The overall response rate was notably higher with the daratumumab combination (92.9%) compared to the control (76.4%), and a significant proportion of patients achieved minimal residual disease negativity (26.2% vs 6.4%), indicating a deeper response without new safety concerns.

In the phase 3 MAIA trial involving 737 patients, the combination of daratumumab, lenalidomide, and dexamethasone significantly improved both progression-free survival (not reached vs. 34.4 months in the control group) and overall survival (hazard ratio 0.68) in patients with newly diagnosed multiple myeloma who were ineligible for stem-cell transplantation.

The safety profile of the treatment was consistent with previous findings, with no new safety concerns identified, although higher rates of neutropenia and pneumonia were observed in the daratumumab group.

In a study of 737 patients with newly diagnosed multiple myeloma, the addition of daratumumab to lenalidomide and dexamethasone significantly reduced the risk of disease progression or death, with a hazard ratio of 0.56, indicating a 44% lower risk compared to the control group.

Patients receiving daratumumab had a higher rate of complete response (47.6% vs. 24.9%) and a greater percentage achieving minimal residual disease status (24.2% vs. 7.3%), although they also experienced more severe side effects like neutropenia and pneumonia.

Daratumumab plus Lenalidomide and Dexamethasone for Untreated Myeloma. Facon, T., Kumar, S., Plesner, T., et al.[2023]

Daratumumab, when combined with lenalidomide and dexamethasone (DRd) or bortezomib and dexamethasone (DVd), showed an overall response rate of 80% in 171 heavily treated patients with relapsed/refractory multiple myeloma, indicating its efficacy in this challenging patient population.

Patients receiving the DRd combination experienced better progression-free survival (PFS) compared to those on DVd, with PFS rates of 84% and 77%, respectively, while the treatment was generally safe, with common side effects including neutropenia and infections.

Intravenous daratumumab, when combined with bortezomib, thalidomide, and dexamethasone, significantly improves treatment outcomes for adults with newly diagnosed multiple myeloma, leading to higher rates of stringent complete response and prolonged progression-free survival, as shown in the phase III CASSIOPEIA trial.

The addition of daratumumab has a minimal impact on overall toxicity, with the most common serious side effects being blood-related issues, indicating it is a relatively safe option for patients undergoing treatment for multiple myeloma.

Daratumumab combined with lenalidomide and dexamethasone showed an impressive overall response rate of 81% in patients with relapsed/refractory multiple myeloma, indicating its efficacy in this challenging patient population.

The treatment was well tolerated, with no dose-limiting toxicities observed and manageable infusion-related reactions, suggesting a favorable safety profile consistent with previous treatments.

Combining lenalidomide with daratumumab significantly enhances the ability of the immune system to kill multiple myeloma cells, as shown in assays using both cell lines and primary patient cells.

The synergy between lenalidomide and daratumumab was particularly evident in the bone marrow environment of multiple myeloma patients, suggesting that this combination could be a powerful treatment strategy in clinical settings.
