WuXi Biologics has commenced construction of a 95,000 square meter microbial manufacturing facility in Chengdu, featuring China's first dual-chamber lyophilization production line.
The facility will house a 15,000L fermenter with expansion potential to 60,000L, enabling production of 80-110 drug substance batches annually and over 10 million vials of drug product.
The site will utilize WuXi's EffiX™ microbial expression platform to manufacture diverse biologics including peptides, antibody fragments, and virus-like particles for global commercial distribution.
Initial production will focus on VISEN Pharmaceuticals' Lonapegsomatropin, a long-acting growth hormone therapy for pediatric growth hormone deficiency, with GMP release scheduled for late 2026.
