     Auditorium at the EHA congress in Amsterdam

Copenhagen, Denmark; June 14 2012 – Genmab A/S (OMX: GEN) announced today the
timing of the oral presentation of preliminary data from the ongoing
daratumumab Phase I/II study in multiple myeloma at the 17th Congress of the
European Hematology Association (EHA) in Amsterdam, June 14-17 2012. 

The presentation details are as follows:
Title: Daratumumab, A CD38 monoclonal antibody in patients with multiple
myeloma – Preliminary efficacy and pharmacokinetics data from a dose-escalation
phase I/II study 

Date: Sunday June 17 2012
Time: 10.45-11am CEST
Presenter: Dr. Henk Lokhorst, University Medical Center Utrecht, Utrecht, The
Netherlands 
The abstract is available on the EHA website:

sId=5650 

Slides from the presentation will be made available on Genmab’s homepage after
the presentation, at the following link www.genmab.com 

The oral presentation covers preliminary safety and efficacy data from the
ongoing Phase I/II study and includes new pharmacokinetics (PK) data which
shows how the antibody is absorbed and distributed in the body of patients. The
PK data showed that at therapeutic dose levels a higher degree of responses
were seen, with most patients exhibiting a significant reduction in key disease
biomarker levels (which include serum M-component, urine M-component and serum
free light chains, measured according to the International Myeloma Working
Group (IMWG) guidelines) showing that the antibody is clinically active in
heavily pre-treated multiple myeloma patients. 

In addition, daratumumab data will be highlighted today at 5.25pm CEST in the
satellite symposium, entitled “Achieving and maintaining disease control in
multiple myeloma”, in a presentation by Dr. Xavier Leleu, entitled ‘Future
therapeutic options on the horizon for multiple myeloma’, and in two further
daratumumab poster presentations at EHA.

About daratumumab
Daratumumab, a human CD38 monoclonal antibody with broad-spectrum killing
activity, is in clinical development for multiple myeloma. The CD38 molecule is
highly expressed on the surface of multiple myeloma cells. Daratumumab could
also have potential in other hematological tumors on which CD38 is expressed,
including diffuse large B-cell lymphoma, chronic lymphocytic leukemia, acute
lymphoblastic leukemia, acute myeloid leukemia, follicular lymphoma and mantle
cell lymphoma.
