BioDlink Congratulates Junshi Biosciences on IND Approval of JS212, a Bispecific ADC Therapeutic Candidate

• BioDlink congratulates Junshi Biosciences on receiving IND approval from China's NMPA for JS212, the company's first bispecific ADC.
• JS212 combines dual-targeting antibody technology with a cytotoxic payload, representing a next-generation therapeutic.
• BioDlink provided end-to-end development and manufacturing support, showcasing its industry-leading ADC capabilities.
• Approval marks a key milestone in the development of next-generation antibody-drug conjugates.

SUZHOU, China, May 8, 2025 /PRNewswire/ -- BioDlink, a leading global CDMO, proudly congratulates its partner Junshi Biosciences (HKEX-1877; SSE-688180), on receiving Investigational New Drug (IND) approval from the National Medical Products Administration (NMPA) of China to initiate clinical trials for the JS212 injection — Junshi Biosciences' first bispecific antibody-drug conjugate (ADC).

JS212 represents a new class of bispecific ADCs that combine the humanized epidermal growth factor receptor and human epidermal growth factor receptor 3 bispecific antibody-drug conjugate to target both EGFR and HER3 — two proteins highly expressed in a variety of tumor cells, such as lung cancer, breast cancer, and head and neck cancer. As a bispecific ADC, JS212 has a key advantage over traditional ADCs that only target one protein: it can attack tumors via either EGFR or HER3, potentially increasing its effectiveness against a wider range of cancers and helping to overcome drug resistance.

Dr. Jun Liu, CEO and Executive Director of BioDlink, stated: "As a leader in ADC technology, BioDlink remains committed to technology innovation and one-stop solution platform for complex biologics. Our collaboration with Junshi Biosciences is built on mutual trust and deep experience in ADC research, development and manufacturing. The IND approval of JS212 — a technically demanding bispecific ADC —­ highlights our strong capabilities and strategic value we bring to partners pursuing next-generation biologics. We're honored to support the advancement of this important program."

Dr. Jing Tong, Deputy Director of Junshi Biosciences' Innovation Research Institute, shared: "We are very pleased with the ongoing and highly productive partnership with BioDlink. Their exceptional expertise and proven capabilities in ADC development and manufacturing have played a pivotal role in advancing JS212 to this important milestone. Throughout the collaboration, BioDlink has consistently demonstrated technical excellence, operational efficiency, and a deep understanding of complex bispecific ADCs. This approval marks a key collaboration milestone, and we look forward to deepening our cooperation as we work toward bringing innovative therapies to patients in the future."
