Dr. Marie Zhu is currently CTO of WuXi XDC with >28 years of experience in drug development at Pfizer, BMS, Xencor, Astellas, and RemeGen. She has led and involved in various novel ADC developments in the past 15 years winning 10+ ADC INDs approved by FDA and 2 ADC BLAs (Padcev approved by FDA, Aidexi approved by NMPA). She earned her Ph.D in Chemical Engineering from University of Wisconsin-Madison, USA
1. WuXiDARx (x= 1, 2, 4, 6) conjunction technologies enable highly homogeneous ADCs without engineering mAbs or applying enzymes, achieving D1 > 90% using WuXiDAR1, D2 > 95% using WuXiDAR2, D4 > 70% - 85% using WuXiDAR4, and D6 > 80% using WuXiDAR6.
2. Application of WuXiDARx beyond traditional ADCs :
DAR1 AOC without engineering mAbs
Dual-payload ADCs with flexible formats (4+4; 2+4; 2+6) using traditional payload-linkers.
3. WuXiTecan-1 and WuXiTecan-2, the proprietary payload-linker (PL) technologies of WuXi XDC, enable next-generation ADCs with a wider therapeutic window, which is crucial for improving the efficacy and safety of ADCs.
