• DARZALEX split dosing regi­men approved by U.S. FDA
• Provides health­care professionals with option to split first DARZALEX in­fusion over two consecutive days
• Approval sup­ported by data from EQUULEUS (MMY1001) clin­i­cal trial

{{image}}Copenhagen, Denmark (Press Release) – Genmab A/S (Nasdaq Copenhagen: GEN) announced today that the U.S. Food and Drug Admin­istra­tion (U.S. FDA) has approved a split dosing regi­men for DARZALEX® (dara­tu­mu­mab). The approval will be in­cluded in an update to the Prescribing Infor­ma­tion in order to provide health­care professionals the option to split the first in­fusion of DARZALEX over two consecutive days. The supple­mental Biologics License Application (sBLA) was submitted by Genmab’s licensing partner, Janssen Biotech, Inc., in July, 2018. The split dosing option was pre­vi­ously approved in Europe by the European Com­mis­sion in December 2018. In August 2012, Genmab granted Janssen an exclusive world­wide license to develop, manu­fac­ture and com­mer­cial­ize dara­tu­mu­mab.

“We are pleased that, with this change, patients in the U.S. receiving their first in­fusion of DARZALEX may now have this more flexible dosing option,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab

This approval was sup­ported by data from the Phase Ib EQUULEUS (MMY1001) clin­i­cal trial, which dem­onstrated DARZALEX phar­ma­co­ki­netics (PK) con­cen­tra­tions were com­parable re­gard­less of whether the first dose was admin­istered as a split in­fusion or as a single first in­fusion in patients with multiple myeloma. The safety profile of DARZALEX was com­parable when admin­istered initially as either a split or a single dose.

About the EQUULEUS (MMY1001) Study

The Phase Ib EQUULEUS open-label study in­cludes up to 240 patients with the goal of eval­u­ating the safety, tolerability and dose of dara­tu­mu­mab when admin­istered in com­bi­na­tion with various back­bone treat­ment regi­mens for dif­fer­en­t settings of multiple myeloma.

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.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 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).^1,2,3,4,5

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.

About Genmab

Genmab is a publicly traded, inter­na­tional bio­technology com­pany specializing in the creation and devel­op­ment of dif­fer­en­ti­ated anti­body thera­peutics for the treat­ment of cancer. Founded in 1999, the com­pany has two approved anti­bodies, DARZALEX® (dara­tu­mu­mab) for the treat­ment of certain multiple myeloma indi­ca­tions, and Arzerra® (ofatumumab) for the treat­ment of certain chronic lym­pho­cytic leukemia indi­ca­tions. Dara­tu­mu­mab is in clin­i­cal devel­op­ment for addi­tional multiple myeloma indi­ca­tions and other blood cancers. A sub­cu­tane­ous for­mu­la­tion of ofatumumab is in devel­op­ment for relapsing multiple sclerosis. Genmab also has a broad clin­i­cal and pre-clinical prod­uct pipe­line. Genmab's tech­nology base consists of val­i­dated and pro­pri­e­tary next generation anti­body tech­nolo­gies - the DuoBody® plat­form for generation of bispecific anti­bodies, the HexaBody® plat­form, which creates effector function en­hanced anti­bodies and the HexElect™ plat­form, which combines two co-dependently acting HexaBody molecules to introduce selectivity while maximizing thera­peutic potency. The com­pany in­tends to leverage these tech­nolo­gies to create oppor­tu­ni­ties for full or co-ownership of future prod­ucts. Genmab has alliances with top tier pharma­ceu­tical and bio­technology com­pa­nies. For more in­for­ma­tion visit www.genmab.com.
