AK154 is Akeso’s first mRNA-based therapeutic candidate to enter clinical development. This achievement marks a significant breakthrough for the company in the field of mRNA technology, following its established leadership in multi-specific antibodies, and entry into the clinic for its antibody-drug conjugates (ADCs).

AK154 is a personalized neoantigen vaccine developed by Akeso using its mRNA platform. It designs sequence-specific mRNA vaccines by sequencing tumor tissue and identifying immunogenic mutations with high affinity. This approach aims to overcome the "cold tumor" phenotype seen in pancreatic cancer.

AK154 shows a synergistic therapeutic effect with Akeso’s bispecific antibodies in enhancing anti-tumor immunity. Preclinical data demonstrated strong immunogenicity, potent anti-tumor activity, and a favorable safety profile. The combination of AK154 with cadonilimab or ivonescimab offers potentially promising new therapeutic options for pancreatic cancer patients.
