Positive feedback reinforces Silexion’s trajectory toward its planned Phase 2/3 trial initiation in Q2 2026

Company plans to complete regulatory submissions to the Israeli Ministry of Health by the end of Q4 2025 and in Germany during Q1 2026

GRAND CAYMAN, Cayman Islands, Dec. 02, 2025 (GLOBE NEWSWIRE) -- Silexion Therapeutics Corp. (NASDAQ: SLXN) (“Silexion” or the “Company”), a clinical-stage biotechnology company developing RNA interference (RNAi) therapies for KRAS-driven cancers, today announced that it has received formal written Scientific Advice from the German Federal Institute for Drugs and Medical Devices (BfArM) regarding the proposed design of the Company’s planned Phase 2/3 clinical trial for SIL204, the Company’s lead product candidate for locally advanced pancreatic cancer. The guidance follows the Company’s Scientific Advice meeting held with BfArM recently and provides significant regulatory clarity as Silexion prepares its Phase 2/3 clinical trial submissions.

The positive response from BfArM is an important milestone for supporting the acceptability of the proposed Phase 2/3 study design, based on the supporting safety data, and manufacturing specifications. The written feedback covers several core components of the program, including clinical design, dosing plans, patient population strategy, nonclinical support, and CMC/manufacturing considerations, and will be incorporated into Silexion’s upcoming regulatory submissions in Israel, which are expected by the end of 2025, and in Germany, which are expected during the first quarter of 2026.

Ilan Hadar, Chairman and Chief Executive Officer of Silexion, commented: “This written Scientific Advice represents a meaningful step in our regulatory path and provides us with the supporting clarity needed to finalize our Phase 2/3 submission packages. SIL204 continues to progress on schedule, and the engagement with BfArM supports the momentum we have built heading into 2026. We remain highly focused on bringing SIL204 into the clinic and advancing a therapy that we believe has the potential to address critical unmet needs in KRAS-mutated cancers.”

Silexion remains on track to initiate its Phase 2/3 clinical trial of SIL204 in the first half of 2026, pending regulatory clearance. The Company continues to advance all other operational and development activities required for trial launch, including manufacturing readiness, toxicology data integration, and clinical site preparations.
