LegoChem Biosciences and Glycotope Announce Research Collaboration and License Agreement for an Antibody for use as Antibody Drug Conjugate

12-Jul-2022 - Germany

LegoChem Biosciences Inc. (LCB) and Glycotope GmbH (Glycotope) have signed a Research Collaboration and License Agreement to develop an antibody drug conjugate (ADC) by combining LCB’s proprietary ADC technology with one of Glycotope’s investigational tumor targeting antibodies.

Under the terms of the agreement LCB has the right to exercise its option for worldwide exclusive rights to develop and commercialize the selected antibody as ADC, upon successful completion of a feasibility study. If LCB exercises these rights, Glycotope will receive an upfront payment as well as development and sales milestone payments plus royalties. Specific financial terms have not been disclosed.

“Through this collaboration, once the candidate ADC is discovered and nominated, Glycotope and LCB plan to advance this very innovative program to clinical stage as a competitive cancer therapy,” said Dr. Yong-Zu Kim, CEO & President of LCB. “We are very pleased that companies with innovative antibody platforms, such as Glycotope have recognized the advantages of LCB’s linker-payload technology, which has been proven to be plasma stable as well as cancer-selectively activated.”

“This exciting collaboration with LegoChem further underlines the value of Glycotope’s unique technology platform and strengthens our leading position in the development of highly specific glyco-epitope targeting antibodies,” added Henner Kollenberg, CEO, Glycotope.

“Our antibodies are designed to deliver increased tumor selectivity. Combining these with LCB’s ADC technology platform offers the opportunity to develop ADCs with potential to perform beyond today’s best standard of care,” said Patrik Kehler, CSO, Glycotope.

ADCs are a type of targeted cancer medicine 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. LCB’s ADC platform technologies overcome the existing limitations of ADCs by imparting a trinity of improved properties, (1) site-specific stable bioconjugation (2) cancer selective linker activation and (3) cancer-selective activation of potent payload, all of which in a significantly broader Therapeutic Window.

Glycotope’s antibodies target specific tumor-associated carbohydrate structures or protein/carbohydrate combined glyco-epitopes (GlycoTargets). Targeting these specific antigens enables broad indication range, long-term treatment potential and reduced on-target/off tumor toxicity, key elements of highly potent therapies. Based on this unrivalled tumor-specificity, Glycotope’s antibodies are highly suitable for a multi-function platform approach with independent modes of action to provide a tailored therapy format for as many patients as possible.
