Silexion Therapeutics (NASDAQ: SLXN) is advancing precision oncology with a focus on KRAS-driven cancers, among the most challenging targets in oncology. In collaboration with Evonik, Silexion has developed a long-acting PLGA microparticle formulation for SIL-204, its next-generation siRNA candidate. Preclinical studies showed high efficacy, with sustained-release therapy effectively reducing tumor size in KRAS-mutated pancreatic cancer models.

Silexion’s RNAi approach silences KRAS mutations at the genetic level, overcoming barriers that limit small-molecule inhibitors. This advancement comes as the oncology industry sees surging M&A activity, such as Pfizer’s $43 billion acquisition of Seagen and AbbVie’s $10.1 billion purchase of Immunogen, reflecting Big Pharma’s demand for innovative cancer therapies.

By targeting a broader range of KRAS mutations (pan-G12x and G13D), SIL-204 holds promise beyond pancreatic cancer, with potential applications in colorectal and lung cancers. Positioned at the center of high unmet medical need and growing market demand, Silexion stands out as a strong contender in the rapidly evolving precision oncology space.

PESG Research Releases an Market Update Report on Silexion Therapeutics (NASDAQ: SLXN). The precision oncology sector has rapidly evolved into one of the most dynamic areas of cancer treatment innovation. Among the key players pioneering novel approaches is Silexion Therapeutics, a clinical-stage biotechnology company focused on RNA interference (RNAi) therapies for KRAS-driven cancers—one of the most prevalent and historically “undruggable” oncogenic drivers. Silexion’s latest announcement, detailing its collaboration with Evonik to develop an advanced siRNA PLGA microparticle formulation for SIL-204, marks another strategic milestone in its quest to transform cancer treatment. This comes as the precision oncology industry experiences rising M&A activity and robust demand for groundbreaking therapies.

KRAS Mutations: A Major Oncology Target

KRAS mutations remain among the most significant challenges in oncology. Found in over 90% of pancreatic cancers and prevalent in colorectal and lung cancers, KRAS mutations drive aggressive tumor growth and resistance to conventional treatments. Despite decades of research, effective targeting of KRAS has proven elusive. While small-molecule KRAS inhibitors like Amgen’s Lumakras and Mirati’s Krazati have made strides in addressing KRAS G12C mutations, these mutations are relatively rare in pancreatic cancer.

Silexion has taken a differentiated approach, utilizing RNAi to silence KRAS mutations at the genetic level. Its Local Drug EluteR (LODER™) platform bypasses the tumor microenvironment’s barriers, delivering siRNA directly into the tumor for localized, high-efficacy treatment. The company’s first-generation LODER platform showed significant promise in Phase 2 trials for non-resectable locally advanced pancreatic cancer (LAPC), extending overall survival by 9.3 months and achieving a 56% objective response rate (ORR) when combined with standard chemotherapy.

The announcement of its collaboration with Evonik, a global leader in specialty chemicals, adds another layer of innovation to Silexion’s strategy. The collaboration has produced a long-acting PLGA microparticle formulation for SIL-204, Silexion’s next-generation siRNA candidate. Preclinical data demonstrated high efficacy in reducing tumor size and inducing tumor necrosis in mouse models with KRAS-mutated human pancreatic tumor cell lines. This formulation enables a sustained-release mechanism, improving stability and precision targeting—critical attributes for therapies in notoriously hard-to-treat cancers like pancreatic cancer.

Strategic Positioning: Expanding Beyond Pancreatic Cancer

Silexion’s SIL-204 represents a significant leap forward in RNAi technology, as it targets a broader range of KRAS mutations (pan-G12x and G13D), making it applicable across multiple cancer types. While its initial focus remains pancreatic cancer, SIL-204’s potential in colorectal and lung cancers opens substantial market opportunities. Colorectal cancer alone is the third most common cancer worldwide, with KRAS mutations implicated in approximately 40-50% of cases.

This pipeline expansion aligns with a broader industry trend where precision oncology therapies target multiple indications driven by shared genetic mutations. Silexion’s localized delivery system, combined with the ability to target a broader set of KRAS mutations, positions the company as a uniquely compelling player in this space.

Industry Dynamics: M&A Appetite for Precision Oncology

The rise of innovative therapies like Silexion’s comes amid a surge in mergers and acquisitions (M&A) activity within the oncology sector. Pharmaceutical giants are aggressively acquiring next-generation oncology assets to bolster their pipelines and address unmet medical needs.

Recent high-profile deals underscore this trend:

  • Pfizer’s $43 billion acquisition of Seagen in 2023 doubled its oncology portfolio, signaling a strong appetite for targeted therapies.
  • AbbVie’s $10.1 billion purchase of Immunogen showcased the premium value placed on precision-targeted treatments.

The KRAS inhibitor market, currently projected to grow at a 36% CAGR, is expected to reach $10 billion by 2032, making it a key focus for Big Pharma’s investment strategies. With over $170 billion in collective cash reserves, major pharmaceutical companies are poised to pursue innovative assets like Silexion’s SIL-204. The unique combination of RNAi technology, sustained-release delivery, and applicability across multiple cancers makes Silexion an attractive acquisition target in a competitive M&A landscape.

Navigating a Transformative Precision Medicine Market

The precision medicine market is projected to grow from $102 billion in 2024 to $470 billion by 2034, driven by advancements in genetic targeting technologies like RNAi and a rising emphasis on personalized therapies. Within this growth, companies like Silexion, leveraging innovative platforms to address high-unmet-need cancers, stand to benefit disproportionately.

While challenges remain—such as the risks inherent in clinical-stage drug development and the still-nascent state of RNAi therapies—Silexion’s collaboration with Evonik demonstrates its strategic focus on overcoming technical barriers to sustained efficacy. This partnership positions SIL-204 to advance into Phase 2/3 trials by 2025-2026, an important milestone for the company’s growth trajectory.

Conclusion: A Strategic Contender in Precision Oncology

Silexion Therapeutics continues to make meaningful strides in addressing one of oncology’s most challenging targets—KRAS-driven cancers. The company’s collaboration with Evonik on the PLGA microparticle formulation for SIL-204 enhances its potential to deliver transformative therapies for pancreatic and other KRAS-driven cancers. Amid rising M&A activity and a growing precision medicine market, Silexion stands at the intersection of high unmet medical need and significant market opportunity. As it advances its clinical pipeline and expands its focus to other cancer types, Silexion’s differentiated approach positions it as a key player to watch in the evolving oncology landscape.

With innovative RNAi technology, strategic collaborations, and a clear roadmap for clinical advancement, Silexion may not only redefine treatment paradigms for KRAS-driven cancers but also emerge as a prime target for pharmaceutical partners seeking cutting-edge assets in precision oncology.
