Altruist Biologics Secures Trilateral Approval for Hangzhou ADC Facility

The site represents a significant infrastructure play for the Innovent Biologics subsidiary, featuring dedicated laboratories for process development, quality control, and manufacturing science. Its technical architecture centers on single-use reactor systems, currently supporting conjugation scales up to 500 liters, with plans to scale capacity to 5,000 liters. To manage the high-potency active pharmaceutical ingredients (HPAPIs) essential to ADC development, the facility maintains an occupational exposure limit of 5 ng/m³ within its high-containment zones.

Beyond production capacity, the Hangzhou plant integrates automated, isolator-based aseptic filling systems and large-scale lyophilization units. According to Dr. Kaisong Zhou, CEO of Altruist Biologics, the regulatory clearance reinforces the firm’s ability to handle complex bioconjugate projects from pre-IND stages through to Phase 3 and process performance qualification. Having managed over 40 ADC and AXC projects to date, the company continues to leverage its global quality framework to meet the stringent requirements of international health authorities.
