Silexion Therapeutics (NASDAQ: SLXN) has reported breakthrough preclinical data for its SIL204 therapeutic candidate, showing promising results in treating KRAS-driven cancers, particularly pancreatic cancer. The orthotopic model studies demonstrated:
- ~70% reduction in tumor cell bioluminescence in AsPC-1 model (KRAS G12D mutation)
- Dose-dependent tumor cell reductions in Panc-1 model
- Up to 80% overall tumor cell reduction in BxPC-3 model
Notably, this marks the first systematic validation of a therapy's ability to suppress metastatic spread through systemic administration. The precision medicine market is projected to grow from $102 billion in 2024 to $470 billion by 2034. Maxim Group maintains a 'Buy' rating with a $9 price target, representing a ~600% premium over current price. The company is preparing to unveil an expanded development plan for SIL204, potentially exploring broader clinical applications.
Silexion Therapeutics (NASDAQ: SLXN) announced positive initial data from orthotopic pancreatic cancer models for their SIL204 treatment. The study demonstrated that subcutaneously administered SIL204 effectively reduces both primary tumor growth and metastatic spread.
Key findings include:
- ~70% reduction in tumor cell numbers in AsPC-1 (KRAS G12D mutation) by day 28
- In Panc-1 (KRAS G12D), tumor cells decreased 12% while control group increased >100% by day 14
- ~80% reduction in BxPC-3 (KRAS wild-type) by day 28
- Significant reduction in metastatic spread across liver, intestine, spleen and stomach in Panc-1 and BxPC-3 models
The results validate SIL204's efficacy in a more clinically relevant setting, where human pancreatic tumor cells are implanted directly into the pancreas. The company is finalizing an updated development strategy based on these findings.
Silexion Therapeutics (NASDAQ: SLXN) is approaching a important milestone with upcoming orthotopic pancreatic cancer model data for its SIL-204 therapy. The study evaluates the treatment's effectiveness in reducing primary tumor growth and inhibiting metastatic spread in pancreatic cancer models.
Previous studies have shown promising results, with SIL-204 demonstrating a 50% reduction in tumor growth and complete necrosis in half of treated tumors. The therapy has maintained therapeutic levels for over 56 days from a single dose. The RNAi-based approach targets multiple KRAS mutations (G12D, G12V, G12R, Q61H, and G13D), potentially offering broader therapeutic benefits than existing treatments.
The data readout, expected in March 2025, could validate systemic efficacy against metastatic disease for the first time. Maxim Group maintains a $9 price target and strong buy rating on SLXN, citing the company's clinical trajectory and RNAi platform validation.
Silexion Therapeutics (NASDAQ: SLXN) has completed its initial study evaluating SIL-204 in orthotopic pancreatic cancer models, marking the first systematic evaluation of this RNA interference therapy administered subcutaneously in clinically relevant models.
The study assessed two critical aspects of SIL-204's potential:
- Ability to reduce primary tumor growth when administered systemically
- Capacity to reduce metastatic spread from orthotopic tumors to secondary organs
Unlike standard subcutaneous xenograft models, the orthotopic models used in this study better represent the complex microenvironment of pancreatic tumors and their metastatic behavior by allowing tumors to develop in their native environment.
Data analysis is currently underway, with initial results expected to be reported in March 2025. These findings will inform Silexion's development strategy for SIL-204 in addressing both localized and metastatic pancreatic cancer.

Silexion Therapeutics (NASDAQ: SLXN) has reported promising preclinical data for SIL-204, its next-generation siRNA therapeutic candidate targeting KRAS-driven cancers. The key findings demonstrate that systemic administration of SIL-204 effectively reduced tumor growth by ~50% after 30 days, with ~50% of tumors showing complete necrosis in human pancreatic tumor models.
The data revealed that SIL-204 can inhibit multiple oncogenic KRAS mutations (G12D, G12V, G12R, Q61H, and G13D) and maintain effective drug levels in rat plasma and tissues for over 56 days after a single administration. In intratumoral administration tests, SIL-204 microparticles reduced tumor cell numbers by ~3-fold, tumor area by ~1.5-fold, and increased tumor necrosis by ~5-fold after 15 days.
The company is now planning further studies to evaluate SIL-204's impact on metastases and expects to announce an expanded development plan for KRAS-driven cancers.
Silexion Therapeutics (NASDAQ: SLXN) has unveiled promising preclinical data for SIL-204, its next-generation siRNA candidate targeting KRAS-driven cancers. The data demonstrates significant synergy between SIL-204 and first-line chemotherapy agents, including 5-fluorouracil, irinotecan, and gemcitabine.
In human pancreatic tumor cell models with KRAS G12D mutations, SIL-204 enhanced the effectiveness of standard therapies, showing greater reductions in cancer cell confluence compared to chemotherapy alone. This is particularly significant as KRAS mutations are present in over 90% of pancreatic cancer cases.
Building on its first-generation LODER™ platform's success in Phase 2 trials, SIL-204 targets a broader spectrum of KRAS mutations. The company plans to begin toxicology studies soon, with Phase 2/3 trials scheduled for 2026. Additionally, Silexion announced a $5 million public offering to support its research efforts.
