We are honored to be one of the few China biotech stocks added to this bellwether index, further demonstrating I-Mab’s growing profile and recognition among the global investor communities,” said Mr. Jielun Zhu, Director and Chief Financial Officer of I-Mab. “As we continue on our journey to become a fully integrated global biopharmaceutical company and execute key value-driving catalysts across our pipeline, from the near-term NDA filing of felzartamab (CD38 antibody) to important data readouts of lemzoparlimab (CD47 antibody) and uliledlimab (CD73 antibody), we are strongly positioned to deliver even greater value to our shareholders.”
