Operational Excellence That Sets a New Benchmark

All technology transfers and GMP production batches were successfully completed at the first go, highlighting BioDlink's strength in quality systems, regulatory alignment, and manufacturing reliability. The collaboration demonstrates how high-performing CDMOs can serve as strategic partners—not just service providers—across the entire lifecycle of cutting-edge therapies.

Dr. Jian Zhang, Chief Operating Officer, BioDlink, remarked, "We are proud to have supported Lepu Biopharma in the development and production of the world's first approved EGFR-Targeting ADC drug—which is also the first fully CDMO-manufactured ADC successfully launched in China. This achievement is not only a breakthrough for the industry but also a testament to our shared vision and execution excellence. This partnership strongly validates BioDlink's commercial-ready capabilities and quality systems."

Dr. Ziye Sui, Executive Director and CEO of Lepu Biopharma, commented, "BioDlink has been far more than a traditional CDMO partner.
