About daratumumab

Daratumumab is a human CD38 monoclonal antibody with broad-spectrum killing activity. Daratumumab is in clinical development for multiple myeloma (MM). Daratumumab targets the CD38 molecule which is highly expressed on the surface of multiple myeloma cells. Daratumumab may also have potential in other cancers on which CD38 is expressed, including diffuse large B-cell lymphoma, chronic lymphocytic leukemia, acute lymphoblastic leukemia, plasma cell leukemia, acute myeloid leukemia, follicular lymphoma and mantle cell lymphoma. Daratumumab has been granted Breakthrough Therapy Designation from the US FDA 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 (IMiD) or who are double refractory to a PI and an IMiD. In August 2012, Genmab granted Janssen Biotech, Inc. an exclusive worldwide license to develop, manufacture and commercialize daratumumab.

About ofatumumab

Ofatumumab is a human monoclonal antibody which targets an epitope on the CD20 molecule encompassing parts of the small and large extracellular loops1. Ofatumumab is being developed under a co-development and collaboration agreement between Genmab and the GlaxoSmithKline group of companies. Ofatumumab is not licensed anywhere in the world as maintenance therapy in relapsed chronic lymphocytic leukemia (CLL), bulky CLL or relapsed or refractory diffuse large B-cell lymphoma (DLBCL).

About HuMax-TAC-ADC

HuMax-TAC is a high-affinity fully human antibody targeting CD25, a therapeutic target with strong clinical validation. CD25 is expressed on a variety of hematological tumors and shows limited expression on normal tissues, which makes it a very attractive target for antibody-payload approaches. With HuMax-TAC-ADC, we aim to develop a first-in-class antibody-drug conjugate for the potential treatment of CD25-expressing lymphomas and leukemias. HuMax-TAC-ADC is being developed under an agreement between Genmab and ADC Therapeutics.

About Genmab A/S

Genmab is a publicly traded, international biotechnology company specializing in the creation and development of differentiated human antibody therapeutics for the treatment of cancer. Founded in 1999, the company currently has one marketed antibody, Arzerra(r) (ofatumumab) for the treatment of certain chronic lymphocytic leukemia indications and daratumumab in late stage clinical development for multiple myeloma. Additionally Genmab has a clinical pipeline with both late and early stage programs, and an innovative pre-clinical pipeline. Genmab's technology base consists of validated and proprietary next generation antibody technologies - the DuoBody(r) platform for generation of bispecific antibodies, and the HexaBody(tm) platform which creates effector function enhanced antibodies. Genmab's deep antibody expertise is expected to provide a stream of future product candidates. Partnering of selected innovative product candidates and technologies is a key focus of Genmab's strategy and the company has alliances with top tier pharmaceutical and biotechnology companies.
