News Genmab Announces European Marketing Authorization for the Subcutaneous Formulation of DARZALEX® (daratumumab) for the Treatment of Patients with Multiple Myeloma Jun 4, 2020 at 3:42 PM CEST 040620_CA24_Dara SC EU Approval Company Announcement Subcutaneous fixed-dosed formulation of DARZALEX® (daratumumab) approved in Europe for the treatment of adult patients with multiple myelomaApproval follows positive opinion by European Committee for Medicinal Products for Human Use (CHMP) in April 2020 and applies to all current daratumumab indications in frontline and relapsed/refractory settingsApproval based on data from Phase III COLUMBA and Phase II PLEIADES studiesIn the studies, the fixed-dose subcutaneous formulation reduced treatment time from hours to minutes and demonstrated similar efficacy and safety with significantly fewer infusion-related reactions compared with the intravenous formulation Copenhagen, Denmark; June 4, 2020 – Genmab A/S (Nasdaq: GMAB) announced today that the European Commission (EC) has granted marketing authorization for the subcutaneous (SC) formulation of DARZALEX® (daratumumab), for the treatment of adult patients with multiple myeloma in all currently approved daratumumab intravenous (IV) formulation indications in frontline and relapsed / refractory settings. The approval follows a Positive Opinion by the CHMP of the European Medicines Agency (EMA) in April 2020. The SC formulation is administered as a fixed-dose over approximately three to five minutes, significantly less time than IV daratumumab, which is given over several hours. Patients currently on daratumumab IV will have the choice to switch to the SC formulation. In August 2012, Genmab granted Janssen Biotech, Inc. (Janssen) an exclusive worldwide license to develop, manufacture and commercialize daratumumab. “We are extremely pleased that patients in Europe with multiple myeloma will now, like patients in the U.S., have the opportunity for treatment with the subcutaneous formulation of daratumumab. With consistent efficacy, and greater convenience for patients and health care providers with dosing time reduced from hours to just minutes and fewer infusion-related reactions, this formulation provides significant benefits for patients,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab The approval was based on data from two studies: the Phase III non-inferiority COLUMBA (MMY3012) study, which compared the SC formulation of daratumumab to the IV formulation in patients with relapsed or refractory multiple myeloma, and data from the Phase II PLEIADES (MMY2040) study, which is evaluating SC daratumumab in combination with certain standard multiple myeloma regimens. The topline results from the COLUMBA study were announced in February 2019 and subsequently presented in oral sessions at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting and the 24th European Hematology Association (EHA) Annual Congress. Updated data of the COLUMBA and the PLEIADES studies were presented during poster sessions at the 61st American Society of Hematology (ASH) Annual Meeting in December 2019. About the COLUMBA (MMY3012) studyThe Phase III trial (NCT03277105) is a randomized, open-label, parallel assignment study that included 522 adults diagnosed with relapsed and refractory multiple myeloma. Patients were randomized to receive either: SC daratumumab, as 1800 mg daratumumab with rHuPH20 2000 U/mL once weekly in Cycle 1 and 2, every two weeks in Cycles 3 to 6, every 4 weeks in Cycle 7 and thereafter until disease progression, unacceptable toxicity or the end of study; or 16 mg/kg IV daratumumab once weekly in Cycle 1 and 2, every two weeks in Cycles 3 to 6, every 4 weeks in Cycle 7 and thereafter until disease progression, unacceptable toxicity or the end of study. The co-primary endpoints of the study are overall response rate and Maximum trough concentration of daratumumab (Ctrough; defined as the serum pre-dose concentration of daratumumab on Cycle 3 Day 1). About the PLEIADES (MMY2040) studyThe Phase II trial (NCT03412565) is a non-randomized, open-label, parallel assignment study that includes 265 adults either newly diagnosed or with relapsed or refractory multiple myeloma. Patients with newly diagnosed multiple myeloma are being treated with 1,800 mg SC daratumumab in combination with either bortezomib, lenalidomide and dexamethasone (D-VRd) or bortezomib, melphalan and prednisone (D-VMP). Patients with relapsed or refractory multiple myeloma are being treated with 1,800 mg SC daratumumab plus lenalidomide and dexamethasone (D-Rd). An additional cohort of patients with relapsed and refractory multiple myeloma treated with daratumumab plus carfilzomib and dexamethasone (D-Kd) was subsequently added to the study. The primary endpoint for the D-VMP, D-Kd and D-Rd cohorts is overall response rate. The primary endpoint for the D-VRd cohort is very good partial response or better rate. About DARZALEX® (daratumumab)DARZALEX® (daratumumab) intravenous infusion is indicated for the treatment of adult patients in the United States: in combination with bortezomib, thalidomide and dexamethasone as treatment for patients newly diagnosed with multiple myeloma who are eligible for autologous stem cell transplant; in combination with lenalidomide and dexamethasone for the treatment of patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant; in combination with bortezomib, melphalan and prednisone for the treatment of patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant; in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of patients with multiple myeloma who have received at least one prior therapy; in combination with pomalidomide and dexamethasone for the treatment of patients with multiple myeloma who have received at least two prior therapies, including lenalidomide and a proteasome inhibitor (PI); and as a monotherapy for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy, including a PI and an immunomodulatory agent, or who are double-refractory to a PI and an immunomodulatory agent.1 DARZALEX is the first monoclonal antibody (mAb) to receive U.S. Food and Drug Administration (U.S. FDA) approval to treat multiple myeloma. DARZALEX is indicated for the treatment of adult patients in Europe via intravenous infusion or subcutaneous administration: in combination with bortezomib, thalidomide and dexamethasone as treatment for patients newly diagnosed with multiple myeloma who are eligible for autologous stem cell transplant; in combination with lenalidomide and dexamethasone for the treatment of patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant; in combination with bortezomib, melphalan and prednisone for the treatment of adult patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplant; for use in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of adult patients with multiple myeloma who have received at least one prior therapy; and as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma, whose prior therapy included a PI and an immunomodulatory agent and who have demonstrated disease progression on the last therapy2.

Daratumumab is a human IgG1k monoclonal antibody (mAb) that binds with high affinity to the CD38 molecule, which is highly expressed on the surface of multiple myeloma cells. Daratumumab triggers a person’s own immune system to attack the cancer cells, resulting in rapid tumor cell death through multiple immune-mediated mechanisms of action and through immunomodulatory effects, in addition to direct tumor cell death, via apoptosis (programmed cell death).1,4,5,6,7 Daratumumab is being developed by Janssen Biotech, Inc. under an exclusive worldwide license to develop, manufacture and commercialize daratumumab from Genmab. A comprehensive clinical development program for daratumumab is ongoing, including multiple Phase III studies in smoldering, relapsed and refractory and frontline multiple myeloma settings. Additional studies are ongoing or planned to assess the potential of daratumumab in other malignant and pre-malignant diseases in which CD38 is expressed, such as amyloidosis and T-cell acute lymphocytic leukemia (ALL). Daratumumab has received two Breakthrough Therapy Designations from the U.S. FDA for certain indications of multiple myeloma, including as a monotherapy for heavily pretreated multiple myeloma and in combination with certain other therapies for second-line treatment of multiple myeloma.
