Silexion Therapeutics Unveils Promising Preclinical Study of SIL204

Silexion's Remarkable Breakthrough with SIL204

Silexion Therapeutics Corp. (NASDAQ: SLXN), a pioneering biotechnology firm committed to developing innovative RNA interference (RNAi) therapies, has revealed compelling preclinical findings regarding its therapeutic candidate, SIL204. This next-generation RNAi treatment is showing exceptional efficacy against various human cancer cell lines, particularly those associated with pancreatic, colorectal, and lung cancers. The implications of these results are monumental, as they may pave the way for addressing significant unmet medical needs in treating KRAS-driven cancers.

Insights from Preclinical Results

The comprehensive analysis of the data acquired by Silexion emphasizes SIL204's remarkable ability to inhibit both the growth and metabolic activity of cancer cell lines exhibiting KRAS G12D mutations. A series of notable observations emerged from these studies, indicating SIL204's effectiveness across multiple cancer types:

• SIL204 demonstrated a significant capacity to impair the proliferation of KRAS G12D mutated colorectal GP2D cells, lung A427 cells, and pancreatic Panc-1 cells.
• A clear dose-dependent response was observed, showcasing an effective inhibition even at nanomolar concentrations.
• The data revealed a remarkable reduction in cell viability in GP2D cells, highlighting SIL204's efficacy, even without the need for additional compounds.
• Importantly, the inhibition rate in GP2D cells reached approximately 90% when exposed to SIL204.

Building on these encouraging findings, Silexion is planning a new study that will focus specifically on examining SIL204's effects on non-small cell lung cancer (NSCLC) cell lines. This upcoming research aims to provide even more insights into SIL204's therapeutic potential.

Strategic Vision and Therapeutic Potential

Silexion's Chairman and CEO, Ilan Hadar, expressed excitement about the potential for SIL204, stating, "These results represent a significant expansion of SIL204's potential therapeutic applications. The efficacy observed across various cancer types validates our RNAi approach targeting KRAS mutations. Our delivery system's potency at low doses could revolutionize treatment strategies, making a difference in high-need areas beyond just pancreatic cancer."

Mechanism of Action

SIL204's design focuses on improving the uptake and intracellular concentrations of its small interfering RNA (siRNA) product, relying on a lipid-conjugated delivery system. The significant tumor proliferation inhibition exhibited by SIL204 across diverse human tumor cell lines demonstrates the therapy's promising clinical potential for treating hard-to-manage KRAS-driven cancers. Chief Scientific Officer, Dr. Mitchell Shirvan, stated, "By targeting KRAS at the RNA level, SIL204 addresses a fundamental genetic disruptor that propels these aggressive tumors. The consistency of our results across different cancer types illustrates the broad therapeutic potential of our technology."

Market Significance and Future Directions

KRAS mutations are prevalent oncogenic drivers in various cancers, contributing significantly to the global treatment market valued at over $30 billion annually. With KRAS mutations implicated in around 90% of pancreatic cancers, 45% of colorectal cancers, and roughly 35% of lung cancers, the need for effective therapies is urgent. Traditional small-molecule treatments have struggled to drug these variants effectively. Silexion's RNAi-based strategy addresses this challenge, offering new hope in the fight against these challenging cancers.
