Daiichi Sankyo, Glycotope ink pact to develop Gatipotuzumab antibody drug conjugate

New Delhi: Daiichi Sankyo Company, Limited and Glycotope GmbH have entered into an exclusive worldwide licensing agreement to develop an antibody-drug conjugate (ADC) by combining Daiichi Sankyo’s proprietary ADC technology with Glycotope’s investigational tumor-associated TA-MUC1 antibody gatipotuzumab (formerly PankoMab-GEX®), building on a previous 2017 option agreement.

Under the terms of the licensing agreement, Daiichi Sankyo has worldwide exclusive rights to develop and commercialize gatipotuzumab as an ADC. Glycotope will receive an upfront payment and is eligible for clinical, regulatory and sales milestone payments, as well as royalties on net sales worldwide from Daiichi Sankyo. Specific financial terms have not been disclosed.

“With the licensing of gatipotuzumab with the intention of developing an ADC, we now have seven novel ADCs in development, which demonstrate our commitment to maximizing the potential of our proprietary ADC payload and linker technology to help address the unmet needs of patients with cancer worldwide,” said Tom Held, Vice President, Head, Antibody-Drug Conjugate Task Force, Oncology Research and Development, Daiichi Sankyo.

“We are excited by the rapid progress we have made in our collaboration with Glycotope and look forward to the continued clinical development of this potentially first-in-class TA-MUC1-targeting ADC.”

“This agreement with Daiichi Sankyo highlights the potential and wide applicability of gatipotuzumab,” said Henner Kollenberg, Managing Director of Glycotope. “Our world-leading glycobiology expertise has allowed us to create a novel anti-TA-MUC1 monoclonal antibody with carbohydrate-mediated tumor-specificity and high-affinity binding. We look forward to continuing to work with Daiichi Sankyo on this ADC program and on the further development of gatipotuzumab in other formats.”

ADCs are targeted cancer medicines that deliver cytotoxic chemotherapy (“payload”) to cancer cells via a linker attached to a monoclonal antibody that binds to a specific target expressed on cancer cells.

Daiichi Sankyo’s proprietary ADC technology is designed to target and deliver chemotherapy inside cancer cells and reduce systemic exposure to the cytotoxic payload (or chemotherapy) compared to the way chemotherapy is commonly delivered.

Gatipotuzumab is an investigational monoclonal antibody that enables tumor-specific binding to a novel carbohydrate-induced conformational epitope, TA-MUC1, which is extensively expressed in many tumor types including ovarian, lung and breast.
