Genmab Announces Plans for New Studies of Daratumumab

Company Announcement

• 3 new Phase III studies of daratumumab planned in multiple myeloma and amyloidosis
• Studies planned to start between second half 2017 and first quarter 2018

Copenhagen, Denmark; May 17, 2017 – Genmab A/S (Nasdaq Copenhagen: GEN) announced today that its partner Janssen Biotech, Inc. plans to start four new studies of daratumumab in multiple myeloma and amyloidosis.  The studies described below are currently planned to start between the second half of 2017 and the first quarter of 2018 and may be subject to change.  DARZALEX is being developed under an August 2012 agreement in which Genmab granted Janssen Biotech, Inc. an exclusive worldwide license to develop, manufacture and commercialize the product. 

• Phase III study of daratumumab in smoldering multiple myeloma
• Phase III study comparing the subcutaneous and intravenous administration of daratumumab in relapsed and refractory multiple myeloma
• Phase III study of daratumumab in combination with bortezomib, cyclophosphamide and dexamethasone for amyloidosis
• Phase II study of subcutaneous daratumumab in combination with standard of care regimens for frontline and relapsed multiple myeloma

The plans for the new studies were announced at Johnson & Johnson’s Pharmaceutical Business Review today.

“Janssen’s expansive development plans for daratumumab emphasize the commitment to test daratumumab broadly in many different clinical settings, which hopefully results in better treatment options for patients,” said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

About DARZALEX^® (daratumumab)
DARZALEX^® (daratumumab) injection for intravenous infusion is indicated in the United States 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 and as a monotherapy for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy, including a proteasome inhibitor (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 (FDA) approval to treat multiple myeloma. DARZALEX is indicated in Europe 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 for use 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.  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. Five Phase III clinical studies with daratumumab in relapsed and frontline multiple myeloma settings are currently ongoing, and additional studies are ongoing or planned to assess its potential in other malignant and pre-malignant diseases on which CD38 is expressed, such as smoldering myeloma, NK/T-cell lymphoma, amyloidosis, myelodysplastic syndromes and solid tumors.  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, other blood cancers, and solid tumors.  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, and the HexaBody^® platform which creates effector function enhanced antibodies.  The company intends to leverage these technologies to create opportunities for full or co-ownership of future products.
