Silexion Therapeutics Reports Breakthroughs From SIL-204 Preclinical Studies

Latest preclinical studies reveal significant
improvements in stability, efficacy, and KRAS targeting range for
next-generation siRNA candidate SIL-204
Silexion Therapeutics Corp. (NASDAQ: SLXN) (“Silexion” or the
“Company”), a clinical-stage biotech developing RNA interference
(RNAi) therapies for KRAS-driven cancers, today announced new
preclinical findings for SIL-204, its second-generation siRNA
candidate, following the optimization of its extended-release
formulation. These latest findings demonstrate that the latest
SIL-204-microparticle formulation can inhibit the growth and induce
necrosis of the human pancreatic cell line that bears the KRAS G12D
mutation xenotransplanted into mice. Given that this mutation
constitutes the largest segment of pancreatic cancer subtypes, it
represents a significant in the development of SIL-204.
Key new pre-clinical findings include:
- Significant Anti-tumor Activity: In recent mouse
xenograft studies, SIL-204 demonstrated substantial tumor reduction
in the human pancreatic tumor cell lines with the KRAS G12D (Panc
-1) mutations using the innovative approach of oncogene silencing
with siRNA. Previous studies showed this effect using unformulated
siRNA with daily injections. The new studies further show this
effect with a single administration of SIL-204 encapsulated in an
extended-release formulation. Moreover, histopathological
examination of treated tumors showed a very high induction of tumor
necrosis.
- Improved Formulation In Vivo: The transition from PLGA
depot rods to PLGA microparticles (MPs) has resulted in a superior
extended-release profile, enhancing the therapeutic potential. We
now report in vivo results indicating that our new modified
PLGA-microparticle formulation has superior properties over
previous extended-release formulations (Loder).
Silexion plans to initiate toxicology studies with SIL-204
within the upcoming months and has plans to advance SIL-204 into
Phase 2/3 clinical trials in the first half of 2026, focusing
initially on locally advanced pancreatic cancer (LAPC) which has a
notoriously high mortality rate. In parallel, the company plans to
initiate preclinical studies for SIL-204, in colorectal cancer
models.
"These optimizations represent a significant step forward in our
development of SIL-204," said Ilan Hadar, Chairman and CEO of
Silexion. "The improvements in cellular uptake and the enhanced
extended-release formulation further strengthen our confidence in
SIL-204's potential. We look forward to commencing our next set of
studies in preparation for our Phase 2/3 clinical trial."
