I-Mab Hangzhou has commenced pilot operation in phase I facility, which is equipped with process development and analytical laboratories and in parallel the construction of phase II facility with an 80,000-square-meter manufacturing floor space was completed in December 2021. The GMP operations and quality systems will be fully compliant with standards and requirements of China's National Medical Product Administration (NMPA), the U.S. Food and Drug Administration (FDA), and the European Medicines Agency (EMA). It also lays the foundation for I-Mab to meet IND (investigational new drug) supply and future commercial demand.
