Genmab Announces Approval Of Darzalex (Daratumumab) In Frontline Multiple Myeloma In Japan Copenhagen, Denmark (Press Release) – Genmab A/S (Nasdaq: GMAB) announced today that the Ministry of Health, Labor and Welfare (MHLW) in Japan has approved the use of DARZALEX (dara­tu­mu­mab) 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 (ASCT). DARZALEX is being devel­oped under an August 2012 agree­ment in which Genmab granted Janssen Biotech, Inc. (Janssen) an exclusive world­wide license to develop, manu­fac­ture and com­mer­cial­ize the prod­uct. Genmab will receive a USD 7 million mile­stone pay­ment from Janssen in connection with the approval and first commercial sale of DARZALEX under the newly ex­panded label. The approval and related mile­stone do not impact the financial guidance issued by Genmab on August 14, 2019.

“Multiple myeloma remains one of the most common forms of blood cancer in Japan and as such, we are en­cour­aged that patients in Japan newly diag­nosed with this dis­ease now have the option to receive a DARZALEX con­taining regi­men,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

The approval is based on data from the Phase III ALCYONE study that showed a reduction of the risk of dis­ease pro­gres­sion or death by 50 per­cent in newly diag­nosed ASCT in­eli­gible multiple myeloma patients when dara­tu­mu­mab is com­bined with bor­tez­o­mib, mel­phalan and pred­ni­sone. This data was presented as a Late-Breaking Abstract at the 2017 American Society of Hematology (ASH) Annual Meeting and published in The New England Journal of Medicine in De­cem­ber 2017.

About the ALCYONE study

This Phase III study (NCT02195479) is a ran­dom­ized, open-label, multi­center study that in­cluded 706 newly diag­nosed patients with multiple myeloma who are in­eli­gible for ASCT. Patients were ran­dom­ized to receive 9 cycles of either VMP [bortezomib (a pro­te­a­some inhibitor), mel­phalan (an alkylating chemotherapeutic agent) and pred­ni­sone (a corticosteroid)] com­bined with dara­tu­mu­mab, or VMP alone. In the dara­tu­mu­mab treat­ment arm, patients received 16 mg/kg of dara­tu­mu­mab once weekly for six weeks (cycle 1; 1 cycle = 42 days), once every three weeks from cycles 2 to 9, once every four weeks from cycle 9 until dis­ease pro­gres­sion. The pri­mary end­point of the study is pro­gres­sion free survival (PFS).

About multiple myeloma

Multiple myeloma is an incurable blood cancer that starts in the bone marrow and is char­ac­ter­ized by an excess proliferation of plasma cells.1 Approximately 6,313 new patients were ex­pec­ted to be diag­nosed with multiple myeloma and approx­i­mately 4,338 people were ex­pec­ted to die from the dis­ease in Japan in 2018.2 Globally, it was esti­mated that 160,000 people were diag­nosed and 106,000 died from the dis­ease in 2018.3 While some patients with multiple myeloma have no symp­toms at all, most patients are diag­nosed due to symp­toms which can in­clude bone problems, low blood counts, cal­cium elevation, kidney problems or in­fec­tions.4

About DARZALEX® (dara­tu­mu­mab)

DARZALEX® (dara­tu­mu­mab) in­tra­venous in­fusion is indicated for the treat­ment of adult patients in the United States: 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.5 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 in Europe 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 ther­apy. The option to split the first in­fusion of DARZALEX over two consecutive days has been approved in both Europe and the U.S. In Japan, DARZALEX is approved in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone, or bor­tez­o­mib and dexa­meth­a­sone, for the treat­ment of adults with re­lapsed or refractory multiple myeloma and 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. DARZALEX is the first human CD38 mono­clonal anti­body to reach the mar­ket in the United Stated, Europe and Japan. For more in­for­ma­tion, visit www.DARZALEX.com.

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).5,6,7,8,9

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, NKT-cell lym­phoma and B-cell and T-cell 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.
