Dr. Derek Ren, the Executive Director and President of Viva Biotech, delivered a speech during the receptions, providing an overview of the Company's progress and highlighted significant technological advancements. Viva Biotech has consistently enhanced its capabilities in CRO/CDMO services, offering comprehensive, end-to-end solutions ranging from structure-based drug development in early stage to commercial drug delivery. Meanwhile, Viva embedded an Equity-for-Service (EFS) model, to create an open collaboration platform for the incubation and growth of innovative biopharmaceutical enterprises on a global scale to address unmet medical needs. After years of dedicated development, Viva Biotech has established multiple research and development centers in Shanghai, Jiaxing, Suzhou, Ningbo, Taizhou, Chengdu, Hangzhou, and other locations. As of June 30, 2023, Viva Biotech boasts a global workforce of 2,271 dedicated professionals.


Dr. Derek Ren further expounded upon Viva Biotech's service philosophy, which revolves around leveraging structure-based drug discovery (SBDD) as its core and establishing an innovative engine for FIC (First-in-Class) new drug development through comprehensive, end-to-end services. He stated that the company, leveraging its strong capabilities in protein production and structural research, employs a wide array of  drug screening platforms such as ASMS, Intact-MS, SPR, Crystal Soaking, as well as Bioassay platforms, chemical services, and DMPK development, these platforms, including computer-aided drug design and artificial intelligence methods, form the backbone of a mature drug development system, resulting in accelerated and more efficient progress throughout the new drug development process.


In keeping with industry trends and innovation, Viva Biotech continues to push the boundaries in realm of new drug development technologies. Dr. Derek Ren highlighted several of the company's recently developed core technology platforms, including DNA-Encoded Library (DEL), Computer-Aided Drug Design and AI-Driven Drug Development Platform (CADD/AIDD), Covalent Compound Library Screening, Crystal Soaking, and Cryo-EM.


DNA-Encoded Library (DEL) Technology Platform


After years of meticulous research and preparation, Viva Biotech has officially launched its DEL technology platform. The cutting-edge platform offers a comprehensive suite of services, including:
(1) Custom synthesis of DEL libraries,
(2) DEL screening,
(3) Expansion of on-DNA hit compounds,
(4) Multi-target optimization and recommendations.

Under the leadership of Dr. Bing Xia, who possesses a deep expertise in DEL drug discovery, the platform will leverage high-quality DEL libraries and efficient screening methods. It will seamlessly integrate with state-of-the-art technology platforms such as SBDD/FBDD, ASMS, and SPR. The integration combine with Viva Biotech’s one-stop drug development platform, will provide a full spectrum of services, spanning target protein production, DEL library construction, affinity screening, custom synthesis of active compounds, and biological assay validation and development. This platform aims to better support the discovery of FIC and Best-in-Class (BIC) drugs, furthering Viva Biotech's commitment to advancing pharmaceutical innovation.
