Grand Cayman, Cayman Islands, April 23, 2025 (GLOBE NEWSWIRE) -- Silexion Therapeutics Corp. (NASDAQ:SLXN) ("Silexion" or the "Company"), a clinical-stage biotechnology company pioneering RNA interference (RNAi) therapies for KRAS-driven cancers, today announced a strategic collaboration with Catalent, a global leader in advanced delivery technologies, clinical development, and manufacturing solutions for therapeutics.
Under the agreement, Catalent will conduct formulation development and clinical manufacturing activities for Silexion's next-generation siRNA candidate, SIL204, at its state-of-the-art facility in Limoges, France. The collaboration will focus on optimizing both the systemic and intratumoral delivery formulations of SIL204, supporting Silexion's recently announced dual-route development strategy designed to target both primary tumors and metastases in KRAS-driven cancers.
This collaboration builds upon Silexion's recently reported breakthrough preclinical data demonstrating SIL204's significant efficacy in reducing both primary tumor growth and metastatic spread in clinically relevant orthotopic pancreatic cancer models. SIL204 targets a broad spectrum of KRAS mutations (including G12D, G12V, G12R, Q61H, and G13D), which are critical drivers in pancreatic, colorectal, and lung cancers.
This collaboration is part of Silexion's comprehensive strategy to advance SIL204 through preclinical development and into clinical trials, with plans to conduct additional toxicology and pharmacodynamic studies throughout 2025, followed by potential regulatory submissions to the Israel Ministry of Health in the second half of 2025 and to the European Union in the first half of 2026.
