Recruitment Completed in Zalutumumab Head and Neck Cancer Pivotal Study

COPENHAGEN, Denmark, June 10, 2009 (GLOBE NEWSWIRE) -- Summary: Genmab has
completed recruitment of patients in the zalutumumab pivotal Phase III study in
refractory head and neck cancer.

Genmab A/S (Copenhagen:GEN) announced today it has completed enrollment of 273
patients in the zalutumumab pivotal Phase III study in refractory head and neck
cancer. Genmab expects to report final results from the study by the end of
2009.

About the trial

The pivotal study includes patients with squamous cell carcinoma of the head and
neck (SCCHN) who are refractory to or intolerant of standard platinum-based
chemotherapy. Patients in the study are randomized into two treatment groups:
zalutumumab in combination with best supportive care or best supportive care
alone. Patients treated with zalutumumab in combination with best supportive
care receive an initial dose of 8mg/kg of zalutumumab, followed by weekly
infusions of a maintenance dose until disease progression. The maintenance dose
is adjusted as necessary until the patient develops a dose limiting skin rash,
up to a maximum dose of 16 mg/kg of zalutumumab. Disease status will be assessed
every 8 weeks by CT scan or MRI according to RECIST criteria until disease
progression and patients will be followed for survival.

The objective of the study is to evaluate the efficacy of zalutumumab in
combination with best supportive care as compared to best supportive care alone
in terms of overall survival. The primary endpoint in the study is overall
survival from randomization until death.
