CK Life Sciences’ Sequencio Therapeutics Presents the Latest Vaccine Research Advancements at the American Association for Cancer Research Annual Meeting

HONG KONG SAR – Media OutReach Newswire – 31 March 2026 – Sequencio Therapeutics Company Limited (“Sequencio”), a subsidiary of CK Life Sciences Int’l., (Holdings) Inc. (“CK Life Sciences”), today announced that five research abstracts will be presented at the American Association for Cancer Research (“AACR”) Annual Meeting 2026, taking place 17–22 April 2026 in San Diego, USA.

These presentations mark Sequencio’s first major scientific unveiling since its formation and showcase significant advancements in next‑generation cancer vaccine technologies based on Sequencio’s proprietary TrueHLA™ Epitope‑to‑Efficacy™ translational design framework, which enables rational, data‑driven vaccine development across circRNA, mRNA, peptide, and protein‑based platforms.

Collectively, Sequencio’s five AACR 2026 presentations highlight a consistent theme: rationally designed cancer vaccines that demonstrate robust immunogenicity and compelling anti‑tumour activity across multiple targets and modalities in preclinical models. These data underscore the strength of Sequencio’s approach to translating antigen selection into functional immune responses and tumour control. Building on this foundation, Sequencio is prioritizing its most promising programs for IND‑enabling studies, with the goal of accelerating select vaccine candidates into early‑stage clinical development through strategic partnerships and global collaboration.

Dr Melvin Toh, Vice President & Chief Scientific Officer of CK Life Sciences, expressed, “Sequencio’s cancer vaccine pipeline continues to advance with strong momentum. Our AACR 2026 presentations underscore both the scientific promise of our vaccines and the disciplined execution driving their progress. We look forward to building on this foundation as we advance next‑generation immunotherapies for patients.”

The AACR Annual Meeting is a gathering central to the global cancer research community, bringing together scientists, clinicians, other healthcare professionals, survivors, patients and advocates every year to share the latest breakthroughs and developments in cancer science and medicine. Last year, the 2025 Annual Meeting attracted 22,100 in-person participants from 85 countries.
