Product: daratumumab in combination with lenalidomide and dexamethasone
- monoclonal antibody. Daratumumab is a human CD38 monoclonal antibody with broad-spectrum killing activity. Daratumumab is in clinical development for multiple myeloma. Daratumumab targets the CD38 molecule which is highly expressed on the surface of multiple myeloma cells. Daratumumab may also have potential in other cancers on which CD38 is expressed, including diffuse large B-cell lymphoma, chronic lymphocytic leukemia, acute lymphoblastic leukemia, plasma cell leukemia, acute myeloid leukemia, follicular lymphoma and mantle cell lymphoma.
- Daratumumab has been granted Breakthrough Therapy Designation from the FDA for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory agent (IMiD) or who are double refractory to a PI and an IMiD.
- In August 2012, Genmab granted Janssen Biotech an exclusive worldwide license to develop and commercialize daratumumab.

- The MAIA (MMY3008) study is a randomized, open-label, multicenter phase III study that includes 737 newly diagnosed patients with multiple myeloma who are not candidates for high dose chemotherapy and ASCT. Patients were randomized to receive either daratumumab in combination with lenalidomide (an immunomodulatory drug) and dexamethasone (a corticosteroid) or lenalidomide and dexamethasone alone. In the daratumumab treatment arm, patients received 16 milligrams per kilogram (mg/kg) weekly for first 8 weeks (Cycles 1 and 2), every other week for 16 weeks (Cycles 3 to 6) and then every 4 weeks (Cycle 7 and beyond) until progression of disease or unacceptable toxicity. Lenalidomide is administered at 25 mg orally on days 1 through 21 of each 28-day cycle, and dexamethasone was administered at 40 mg once a week for both treatment arms. Participants in both treatment arms will continue Rd until disease progression or unacceptable toxicity. The primary endpoint of the study is PFS. (NCT02252172)
- • On October 29, 2018, Genmab announced topline results from the Phase III MAIA study (MMY3008) of daratumumab in combination with lenalidomide and dexamethasone (DRd) versus Rd alone as treatment for newly diagnosed patients who are not candidates for high dose chemotherapy and autologous stem cell transplant (ASCT).
- The study met the primary endpoint of improving progression free survival (PFS) at a pre-planned interim analysis (Hazard Ratio (HR) = 0.55 (95% CI 0.43 – 0.72), p < 0.0001) resulting in a 45% reduction in the risk of progression or death in patients treated with DRd. The median PFS for patients treated with daratumumab in combination with Rd has not been reached, compared to an estimated median PFS of 31.9 months for patients who received Rd alone.
- Overall, the safety profile of daratumumab in combination with Rd is consistent with both the known safety profiles of the Rd regimen and daratumumab.
- Based on the results at the pre-planned interim analysis conducted by an Independent Data Monitoring Committee (IDMC), it was recommended releasing the interim analysis results. Further analysis of the safety and efficacy data is ongoing and Janssen Biotech will discuss the potential for a regulatory submission for this indication with health authorities, and plans to submit the data to an upcoming medical conference and for publication in a peer-reviewed journal.
- • On August 11, 2014, Genmab announced that its collaboration partner, Janssen Biotech, plans to start a new Phase III study of daratumumab in multiple myeloma. The study (MMY3008) will compare daratumumab in combination with lenalidomide and dexamethasone to lenalidomide and dexamethasone alone as front line treatment for patients who are not considered candidates for stem cell transplantation (SCT). The study is planned to start in the first half of 2015. The first Phase III study in front line multiple myeloma was announced in July and is expected to start towards the end of this year. This latest study is the fourth daratumumab Phase III study to be announced.
