BEIJING – Antibody developer Akeso Biopharma Inc., from China's Guangdong province, closed a $150 million series D financing round to advance its pipeline, especially the two PD-1-based bispecific antibodies, AK-104 and AK-112, aimed to help it stand out in the fierce PD-1 space in China. "A significant portion of the proceeds will go to AK-104 and AK-112, which are both first-in-class drug candidates," Akeso CEO Michelle Xia told BioWorld. This year is a big one for Akeso, as AK-104 and AK-112 received IND approvals from the FDA in March and July, respectively.
