Silexion says SIL204 boosts FAS, cuts HLA-G in preclinical KRAS-mutant cancer studies

• Silexion Therapeutics reported new preclinical data for SIL204 showing immune-sensitizing effects in KRAS-mutant pancreatic cancer and NSCLC cell lines.
• SIL204 increased FAS (CD95) expression at 72 hours, including up to about 2-fold in KRAS G12D pancreatic cells (P<0.0001).
• SIL204 reduced HLA-G expression in KRAS G12C NSCLC cells, including at 24 hours (P<0.001) and 72 hours (P<0.01) at 200 nM.
• Results build on May 2026 findings of MHC-I upregulation, supporting a combination rationale with anti-PD-(L)1 checkpoint inhibitors.
• The company is advancing SIL204 into Phase 2/3 evaluation, citing initiation of its first clinical trial site in late July 2026.
