Silexion Therapeutics Receives Approval from Israeli Ministry of Health to Initiate Phase 2/3 Clinical Trial of SIL204 in Locally Advanced Pancreatic Cancer
Significant regulatory milestone marks advancement into clinical-stage development of next-generation RNAi therapy featuring an innovative, integrated systemic treatment delivery approach targeting highly prevalent KRAS-driven cancers with significant unmet medical need
Company reported strong positive preclinical study results demonstrating significant anti-tumor activity in multiple models and announced successful completion of toxicology studies, and constructive regulatory engagement supporting the Phase 2/3 trial design
Silexion expects to initiate human clinical trials in the second quarter of 2026
Grand Cayman, Cayman Islands, March 24, 2026 (GLOBE NEWSWIRE) -- / CORRECTING / Silexion Therapeutics Corp. (NASDAQ: SLXN) ("Silexion" or the "Company"), a clinical-stage, oncology-focused biotechnology company, today announced that it has received formal approval from the Israeli Ministry of Health to initiate its Phase 2/3 clinical trial evaluating SIL204 for the treatment of locally advanced pancreatic cancer, following positive preclinical results that demonstrated significant anti-tumor activity in mulitple models alongside successful completion of toxicology studies.
This approval represents a major regulatory milestone and a critical advancement for the Company, enabling the transition of SIL204 into human clinical evaluation and positioning Silexion as a clinical-stage biotechnology company focused on KRAS-driven cancers.
SIL204 is designed to silence KRAS mutations, which are present in over 90% of pancreatic cancers and are widely recognized as one of the most challenging targets in oncology. Unlike mutation-specific approaches, SIL204 is engineered to target a broad range of KRAS mutations, supporting its potential applicability across multiple high-value cancer indications.
The approval follows a series of major positive developments achieved by the Company, including strong positive anti-tumor activity demonstrated in multiple preclinical models, successful completion of toxicology studies, and constructive regulatory engagement supporting the Phase 2/3 trial design. Together, these achievements have enabled SIL204 to advance toward clinical-stage development. The Company also plans to submit a Phase 2/3 clinical trial application in Germany by the end of this current quarter, with additional regulatory filings across the European Union planned in early 2027.
“The receipt of this approval marks a defining and highly significant milestone for Silexion,” said Ilan Hadar, Chairman and Chief Executive Officer of Silexion Therapeutics. “We are now advancing SIL204 into a pivotal clinical trial with the goal of addressing KRAS-driven cancers at their source. This progress reflects the strength of our data, the safety demonstrated during the Loder (predecessor to SIL204) clinical trial, the urgency of the unmet need in pancreatic cancer, and our continued execution toward developing a potentially transformative therapy.”
The Company expects to initiate the Phase 2/3 trial in the second quarter of 2026, subject to site activation and standard clinical readiness procedures, and plans to advance SIL204 as a potential treatment across additional KRAS-driven indications, including colorectal and lung cancers.*
