South Korea-based DAAN Biotherapeutics has signed an exclusive licensing agreement with LigaChem Biosciences for a novel tumor-targeting antibody to advance the development and commercialization of Antibody-Drug Conjugates (ADC).

By leveraging DAAN Biotherapeutics’ next-generation antibody technology, built upon its exceptional target discovery and antibody development capabilities, LigaChem Biosciences is now positioned to take a significant step forward in ADC development for solid tumor patients.

DAAN Biotherapeutics has successfully established a proprietary pipeline for efficiently developing antibodies targeting over-expressed tumor targets in solid cancers through a strategic partnership with OmniAb.

“We will continue to develop state-of-the-art antibodies targeting solid tumors and collaborate with global pharmaceutical companies in the ADC field,” noted Byoung Chul Cho, MD, and Choef Executive Officer of DAAN Biotherapeutics.
