At the opening day of BIO Asia-Taiwan 2024, Dr. Gui-Dong Zhu, CEO of SparX Group, introduced the Nab2<\/sup>-ADC<\/strong> platform technology during Session 4 on ADC Drug Development and Manufacturing Trends, Challenges, and Solutions. This marked the first official release of SparX\u2019s innovative technology, which addresses major limitations of current ADC therapies, including off-target side effects, most prominently interstitial lung disease (ILD), and suboptimal targeting efficiency.<\/p>\n\n\n\n

In his presentation, Dr. Zhu detailed the evolution of the Nab2<\/sup>-ADC<\/strong> platform and the cutting-edge technologies supporting its implementation. The nanobody-based design of Nab2<\/sup>-ADC<\/strong>, coupled with its smaller molecular weight, effectively mitigates critical limitations of current ADCs. These include the risk of ILD, inadequate targeting efficiency, slow tumor penetration, and immunoglobin-driven off-target toxicity.<\/p>\n\n\n\n

Nab2<\/sup>-ADC<\/strong> boasts advanced targeting efficiency by utilizing bifunctional antibodies to recognize two distinct epitopes on separate antigens, or biparatopic antibodies to bind two epitopes on the same antigen simultaneously. This design significantly enhances targeting precision. By eliminating the Fc region responsible for non-specific binding to healthy tissues expressing Fc\u03b3R<\/strong>, Nab2<\/sup>-ADC<\/strong> not only improves targeting efficiency but also reduces the risk of ILD through decreased macrophage uptake in the lungs. Additionally, the nano-sized bispecific antibodies in Nab2<\/sup>-ADC<\/strong> ensure deeper and more efficient drug infiltration to the tumor microenvironment, maximizing cytotoxic effects even in hard-to-reach tumor cells.<\/p>\n\n\n\n

Dr. Zhu also highlighted the powerful SparxNano\u2122<\/strong> platform for nanobody discovery, the true site-specific uniQon\u2122<\/strong> conjugation, and the Diturbo\u2122 stable cell line development technologies. These innovations provide robust solutions for the discovery and manufacturing challenges of Nab2<\/sup>-ADC<\/strong>.<\/p>\n\n\n\n

As a testament to the potential of the Nab2<\/sup>-ADC<\/strong> platform, Dr. Zhu introduced SPX-802, a first-in-class (FIC) anti-PD-L1\/VEGF-DXdd2<\/sup> ADC<\/strong>. SPX-802 demonstrates superior tumor cell internalization, efficient lung delivery via<\/em> inhalation, high bioavailability of subcutaneous drug administration, and excellent in vivo<\/em> efficacy in humanized tumor models.<\/p>\n\n\n\n
