Company Announcement

  • IND for HuMax(R)-TF-ADC submitted to FDA
  • Genmab's first IND submission for antibody-drug conjugate (ADC) product
  • Patient enrolment in clinical trial expected to start in 2013

COPENHAGEN, Denmark, July 18, 2013 (GLOBE NEWSWIRE) -- Genmab A/S (Copenhagen:GEN) announced today the filing of an Investigational New Drug (IND) application with the US Food and Drug Administration (FDA) to start a Phase I dose escalation trial of HuMax-TF-ADC to treat multiple solid tumors. A maximum of 78 patients with cancer of the ovary, cervix, endometrium, bladder, prostate, head & neck, esophagus or lung that have failed or are not eligible for standard treatments will be enrolled in the study. The safety and tolerability of HuMax-TF-ADC will be established during a dose escalation part of the study. This will be followed by a cohort expansion part that will investigate longer-term safety and potential signs of anti-tumor activity.

"HuMax-TF-ADC has shown an impressive ability to induce tumor regression in multiple pre-clinical cancer models. We aim to start the clinical evaluation of HuMax-TF-ADC in the coming months, adding another antibody, with the potential to help cancer patients, to Genmab's clinical pipeline," said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

About HuMax-TF-ADC

HuMax-TF-ADC is an antibody-drug conjugate (ADC) composed of a human antibody against tissue factor (TF) conjugated to the cytotoxic drug monomethyl auristatin E (MMAE). HuMax-TF-ADC is being developed for the treatment of solid cancers. TF is an attractive tumor target because of its high expression in a broad range of solid cancers. After binding to TF, HuMax-TF-ADC enters the tumor cells where the cytotoxic agent is specifically released, leading to cell death. HuMax-TF-ADC was demonstrated to have potent anti-tumor activity in in vivo studies in mouse models in which a diverse panel of patient-derived tumors was assessed. HuMax?TF?ADC was shown to have an acceptable safety profile in non-clinical safety studies.

Genmab is developing HuMax-TF-ADC using Seattle Genetics' ADC technology under an agreement between the companies. Seattle Genetics may elect to co-develop HuMax-TF-ADC with Genmab at the end of Phase I clinical development.
