Company Announcement

  • Genmab will not exercise co-development right, retains 25% ownership of HuMax(r)-TAC-ADC
  • Collaboration partner ADC Therapeutics intends to submit IND application for HuMax-TAC-ADC

COPENHAGEN, Denmark, March 16, 2015 (GLOBE NEWSWIRE) -- Genmab A/S (Copenhagen:GEN) announced today it has decided not to exercise the co-development right for HuMax-TAC-ADC under its agreement with ADC Therapeutics Sarl. Genmab will retain 25% of the rights to the product. Under the terms of the companies' agreement, Genmab had a 50% ownership stake with an option to maintain equal ownership of HuMax-TAC-ADC prior to the submission of an Investigational New Drug (IND) application and fund half of the development costs. Genmab has decided not to maintain its co-development right for HuMax-TAC-ADC, but will retain a 25% ownership stake in the product. ADC Therapeutics has indicated it intends to file an IND for HuMax-TAC-ADC in the first half of 2015.

"While we have decided not to fund co-development of HuMax-TAC-ADC with ADC Therapeutics, we are pleased to still have 25% of the rights to the product, which has potential to become a first-in-class antibody-drug conjugate therapeutic in certain hematological cancer indications," said Jan van de Winkel, Ph.D., Chief Executive Officer of Genmab.

About HuMax-TAC-ADC

HuMax-TAC-ADC is an ADC combining Genmab's HuMax-TAC antibody and ADC Therapeutics' PBD-based warhead and linker technology. HuMax-TAC-ADC targets CD25, which 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. HuMax-TAC-ADC has the potential to be a first-in-class antibody-drug conjugate for the treatment of CD25-expressing lymphomas and leukemias. HuMax-TAC-ADC is in development under an agreement between Genmab and ADC Therapeutics.

About PBD Warheads & Linkers

ADCs developed using ADC Therapeutics' technology combine monoclonal antibodies specific to particular tumor targets with highly potent pyrrolobenzodiazepine (PBD) based warheads developed by ADC Therapeutic's partner Spirogen Limited. These PBD warheads are joined to antibodies by linkers that release the PBD warhead in the targeted cancer cells. This technology has attracted the attention of other biotechnology companies such as Genentech and Seattle Genetics.
