NextCure and LegoChem Biosciences Enter into Collaboration and Co-Development Agreement to Develop Antibody Drug Conjugates

NextCure, Inc. and LegoChem Biosciences, Inc. announced a collaboration and co-development agreement focused on generating a B7-H4 antibody drug conjugate (ADC) and options for two additional targets. The B7-H4 ADC will utilize NextCure’s B7-H4 antibody and LCB’s ConjuAllTM ADC technology.

Under the terms of the agreement, both parties will equally share the costs to develop the molecules and profits on commercialized products. The parties will utilize their respective product development capabilities to generate the B7-H4 ADC and advance it to the clinic. In addition, there are options for the parties to nominate two additional targets for ADC development beyond B7-H4.

“We are excited to work with LCB, and apply ConjuAllTM, a leading ADC technology, to add a new treatment modality to our B7-H4 program,” said Timothy Mayer, NextCure’s Chief Operating Officer. “We remain committed to developing novel immunomedicines using multiple modalities to address the significant unmet needs of cancer patients not adequately addressed by available therapies.”

“The initiation of this collaboration with NextCure represents another important milestone for LCB as we continue to build our ADC pipeline and seek to demonstrate the potential of our ADC platform in a wide range of different tumors,” said Yong-Zu Kim, LCB’s Chief Executive Officer. “B7-H4 ADC would potentially offer a first-in-class opportunity for a target expressed on a broad range of tumor types, and I look forward to progress in early stage studies.”
