• DARZALEX (dara­tu­mu­mab) approved by U.S. FDA in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone for the treat­ment of adult patients with newly diag­nosed multiple myeloma who are in­eli­gible for au­tol­o­gous stem cell trans­plant
• Approval based on Phase III MAIA study

Copenhagen, Denmark (Press Release); June 27, 2019 – Genmab A/S (Nasdaq Copenhagen: GEN) announced today that the U.S. Food and Drug Admin­istra­tion (U.S. FDA) has approved the use of DARZALEX® (dara­tu­mu­mab) in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone (Rd) for the treat­ment of adult patients with newly diag­nosed multiple myeloma who are in­eli­gible for au­tol­o­gous stem cell trans­plant (ASCT). The supple­mental Biologics License Application (sBLA) for this indi­ca­tion was submitted by Genmab’s licensing partner, Janssen Biotech, Inc., under the Real-Time Oncology Review (RTOR) pilot pro­gram. In August 2012, Genmab granted Janssen Biotech, Inc. an exclusive world­wide license to develop, manu­fac­ture and com­mer­cial­ize dara­tu­mu­mab.

“The com­bi­na­tion of lena­lido­mide and dexa­meth­a­sone is broadly used by newly diag­nosed patients with multiple myeloma in­eli­gible for ASCT in the United States. We are extremely pleased that physicians can now offer their patients the option to add DARZALEX to this regi­men in the U.S.,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

The approval was based on data from the Phase III MAIA (MMY3008) study of dara­tu­mu­mab in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone as treat­ment for patients with newly diag­nosed multiple myeloma, who are not can­di­dates for high dose chemo­ther­apy and ASCT. Data from this study was presented as a Late-Breaking Abstract at the 2018 American Society of Hematology (ASH) Annual Meeting 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 was 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 treat­ment with lena­lido­mide and dexa­meth­a­sone until disease pro­gres­sion or unacceptable toxicity. The pri­mary end­point of the study is pro­gres­sion free survival.

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 Multiple myeloma is the third most common blood cancer in the U.S., after leukemia and lym­phoma.² Approximately 26,000 new patients were ex­pec­ted to be diag­nosed with multiple myeloma and approx­i­mately 13,650 people were ex­pec­ted to die from the disease in the U.S. in 2018.³ Globally, it was esti­mated that 160,000 people were diag­nosed and 106,000 died from the disease in 2018.⁴ 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.⁵

About DARZALEX® (dara­tu­mu­mab)

DARZALEX® (dara­tu­mu­mab) in­tra­venous in­fusion is indicated in the United States in com­bi­na­tion with lena­lido­mide and dexa­meth­a­sone for the treat­ment of adult 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.6 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. 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).^6,7,8,9,10

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.
