• Supplemental new drug appli­ca­tion (sNDA) submitted in Japan for dara­tu­mu­mab in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone as treat­ment for patients newly diag­nosed with multiple myeloma who are not can­di­dates for high-dose chemo­ther­apy and au­tol­o­gous stem cell trans­plant
• Submission based on data from Phase III MAIA study

Copenhagen, Denmark (Press Release) – Genmab A/S (Nasdaq Copenhagen: GEN) announced today that Janssen Pharma­ceu­tical K.K. has submitted a supple­mental new drug appli­ca­tion (sNDA) to the Ministry of Health, Labor and Welfare (MHLW) in Japan, for the use of dara­tu­mu­mab (DARZALEX®) in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone (Rd) as treat­ment for patients newly diag­nosed with multiple myeloma who are not can­di­dates for high-dose chemo­ther­apy and au­tol­o­gous stem cell trans­plant (ASCT). The MHLW will grant a priority review of the appli­ca­tion, based on the Orphan Drug Desig­na­tion given to DARZALEX for patients with newly diag­nosed multiple myeloma. In August 2012, Genmab granted Janssen an exclusive world­wide license to develop, manu­fac­ture and com­mer­cial­ize dara­tu­mu­mab.

“This marks the third major regu­la­tory sub­mission based on the MAIA data, fol­low­ing similar sub­missions earlier this year in the U.S. and Europe. The regu­la­tory approvals will make dara­tu­mu­mab plus lena­lido­mide and dexa­meth­a­sone a viable option for newly diag­nosed multiple myeloma patients in these three major mar­kets,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

The sub­mission is based on data from the Phase III MAIA study of dara­tu­mu­mab in com­bi­na­tion with Rd as treat­ment for patients newly diag­nosed with multiple myeloma, who are not can­di­dates for high dose chemo­ther­apy and ASCT. Data from the study was presented at the 60th American Society of Hematology Annual Meeting, which took place in San Diego, California in December 2018.

About the MAIA (MMY3008) study

The Phase III study (NCT02252172) is a ran­dom­ized, open-label, multi­center 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.

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) injection for in­tra­venous in­fusion is indicated in the United States 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 treat­ment of adults with re­lapsed or refractory multiple myeloma. DARZALEX is the first human CD38 mono­clonal anti­body to reach the mar­ket. 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 frontline multiple myeloma settings and in amy­loid­osis. Additional studies are ongoing or planned to assess the poten­tial of dara­tu­mu­mab in other malignant and pre-malignant diseases, such as NKT-cell lym­phoma, B and T-ALL. Dara­tu­mu­mab has received two Break­through Therapy Desig­na­tions from the U.S. FDA, for multiple myeloma, as both a mono­therapy and in com­bi­na­tion with other ther­a­pies.
