Mycenax Biotech Inc., recognized as a leading Contract Development and Manufacturing Organization (CDMO) in biologics, has reached a significant milestone by signing a License Agreement with RIN Institute, a prominent entity based in Japan. Announced on October 31, 2025, this collaboration empowers Mycenax with the rights to leverage RIN's proprietary Val-Leu-Lys (VLK) linker technology across its CDMO services on a global scale.
The VLK linker technology developed by RIN is gaining attention for its impressive anti-tumor effectiveness combined with high stability in serum. This advancement is set to elevate the design and production of Antibody-Drug Conjugates (ADCs), a vital component in the fight against cancer. By enabling cytotoxic properties through two distinct action mechanisms within tumor environments, this linker technology also enhances the internalization of ADCs, thus making them more effective against malignancies.
Pei-Jiun Chen, CEO and President of Mycenax, expressed enthusiasm regarding the agreement, stating, "We are thrilled to finalize this agreement with RIN Institute, marking an important milestone in our mission to provide innovative and competitive ADC solutions." This pact is expected to substantially increase Mycenax's capabilities in delivering tailored ADC products that meet the demanding standards of global pharmaceutical partners.
This partnership is built upon previously established foundations, including a Letter of Intent (LOI) signed on April 7, 2025, which set the stage for more structured cooperation aimed at pushing the boundaries of ADC innovation. With this agreement, Mycenax aims to solidify its position as a leader in the ADC domain, transforming research advancements into tangible therapeutic solutions.
