Full Press Release Details

GRAND CAYMAN, Cayman Islands, May 21, 2025 (GLOBE NEWSWIRE) -- Silexion Therapeutics Corp (NASDAQ: SLXN) (“Silexion” or the “Company”), a clinical-stage biotech company developing RNA interference (RNAi) therapies for KRAS-driven cancers, today announced the completion of a comprehensive preclinical study assessing SIL204's therapeutic potential across multiple cancer types beyond pancreatic cancer. The Company is currently finalizing its analysis of the data and expects to announce comprehensive results within the next few days.
The now-completed studies evaluated SIL204, the Company's next-generation RNAi therapeutic candidate, in multiple cancer cell lines harboring KRAS mutations: GP2D (colorectal cancer), A427 (lung cancer), and Panc-1 (pancreatic cancer). These cancer types were strategically selected based on their high prevalence of KRAS mutations and significant unmet medical needs.
"Completing this expanded preclinical evaluation represents an important milestone in our SIL204 development program," said Ilan Hadar, Chairman and CEO of Silexion Therapeutics. "While our initial focus has been on pancreatic cancer, we recognized the potential of our RNAi approach to address other KRAS-driven malignancies. We look forward to sharing the detailed results from these studies in the coming days after completing the final analysis of the studies data. If positive, we believe these results have the potential to significantly expand our development strategy going forward."
KRAS mutations are among the most common oncogenic drivers in human cancers, occurring in roughly 90% of pancreatic cancers, about 45% of colorectal cancers, and around 35% of non-squamous non-small-cell lung cancers. Together, these three indications underpin global treatment markets already worth well over US $30 billion a year1, yet most KRAS variants remain difficult to drug with small-molecule or antibody approaches—underscoring the potential significance of Silexion’s RNAi-based strategy.
About Silexion Therapeutics
