Significant progress in preclinical pipeline targeting KRAS-driven solid tumor cancers with systemic administration demonstrating robust anti-tumor and anti-metastasis activity in orthotopic mouse models; Recent funding strengthens the company’s ability to deliver long term value

Grand Cayman, Cayman Islands, March 18, 2025 (GLOBE NEWSWIRE) -- Silexion Therapeutics Corp. (NASDAQ: SLXN) ("Silexion" or the "Company"), a clinical-stage biotechnology company pioneering RNA interference (RNAi) therapies for KRAS-driven cancers, today reported its financial results for the fourth quarter and full year ended December 31, 2024, and provided a corporate update.

Ilan Hadar, Chairman and CEO of Silexion, commented: “2024 was a transformative year for Silexion, marked by our Nasdaq listing and the advancement of our clinical and preclinical pipeline. Over the past year, we made important progress, culminating in significant milestones especially for our second-generation candidate SIL204. In early 2025, we reported breakthrough findings from orthotopic pancreatic cancer models demonstrating SIL204’s ability to significantly reduce both primary tumor burden and metastatic spread. These results reinforce SIL204’s potential as a novel therapeutic for KRAS-driven cancers, bringing us closer to clinical development. We remain focused on advancing SIL204 towards trials and expanding its potential applications to address unmet needs in oncology.”

Recent Business and Clinical Highlights

• Merger Completion: On August 15, 2024, Silexion completed its business combination with Moringa Acquisition Corp, becoming a publicly traded company on Nasdaq under the ticker “SLXN.” This strategic milestone provides Silexion with greater access to capital to advance its clinical pipeline
• Clinical Program Progress: The Company's first-generation candidate, LODER™, has previously demonstrated promise in clinical settings for non-resectable pancreatic cancer. As previously reported on September 24, 2024, the Phase 2 trial of LODER showed a 56% objective response rate (ORR) in patients with KRAS G12D/V mutations, with tumor resectability improving to 67% for some non-resectable cases. The trial data underscore LODER’s potential to improve surgical outcomes and overall survival for patients with locally advanced pancreatic cancer (LAPC).
• Significant Preclinical Advancements for SIL204: As previously reported, SIL204 exhibited a marked reduction in tumor growth following systemic administration in preclinical pancreatic cancer models. The latest SIL204-microparticle optimized extended-release formulation was shown to inhibit tumor growth and induce necrosis of the human pancreatic cell line bearing the KRAS G12D mutation xenotransplanted into mice. Since then, Silexion has continued to make significant preclinical advancements. In January 2025, data confirmed that a single systemic dose of SIL-204 maintained effective drug levels for over 56 days, supporting its potential for long-term therapeutic exposure. Building on this progress, February 2025 marked the completion of Silexion’s first study in orthotopic pancreatic cancer models, which better simulate human disease progression. March 2025 results confirmed that systemically administered SIL-204 significantly reduced both primary tumor burden and metastatic spread to secondary organs, including the liver, intestine, spleen, and stomach.
• Advancing Toward SIL204 Clinical Trials: As previously reported on October 1, 2024, Silexion is preparing SIL204 for toxicology studies, with plans to initiate Phase 2/3 clinical trials by the first half of 2026, targeting LAPC.
• Exploring Colorectal Cancer Applications: In parallel, the Company plans to initiate preclinical studies for SIL204 in colorectal cancer models, expanding its potential applications across additional KRAS-driven cancers, as previously reported on October 1, 2024.
• Board Appointments: In December 2024, Prof. Amnon Peled was appointed to the Board of Directors. Prof. Peled is a renowned expert in cancer therapeutics and a globally recognized scientific authority who has been involved in multiple successful publicly traded bio-pharma companies.
• Strengthened Financial Position: During 2024, the Company utilized its Equity Line of Credit (ELOC), raising approximately $3.1 million in net proceeds to support its development and growth. Notably, after the reporting date, Silexion successfully received further funding through a previously announced priced offering, a warrant inducement transaction, and warrant exercises, together totaling approximately $9.1 million in gross proceeds (approximately $7.9 million net of transaction costs), extending the Company's operational runway.
  

Mirit Horenshtein Hadar, Chief Financial Officer of Silexion, commented: "Our transition to a publicly traded company in 2024 provided critical access to capital that has allowed us to advance our clinical pipeline. The recent successful financings, including those in early 2025, further reinforce our ability to support ongoing and upcoming development initiatives. With a strengthened financial foundation, we remain focused on executing our strategic objectives and driving long-term growth."

Full Year 2024 Financial Highlights

• Cash Position: Cash and cash equivalents as of December 31, 2024, were $1.2 million, compared to $4.6 million as of December 31, 2023. The decrease reflects ongoing operational expenses and strategic investments in clinical development. Since the reporting date, the Company has successfully received further funding through a previously announced priced offering, warrant inducement transaction, and warrant exercises, together totaling approximately $9.1 million in gross proceeds (approximately $7.9 million net of transaction costs).     
• Operating Expenses: Total operating expenses for 2024 were $12.6 million, compared to $4.7 million in 2023. This increase includes significant one-time expenses related to the business combination and becoming a public company, including, among others, $5.8 million in share-based compensation associated with the business combination. Research and development expenses increased by $2.1 million to $5.8 million (compared to $3.7 million in 2023), primarily due to $2.3 million in one-time non-cash share-based compensation expenses related to employee grants issued at the time of the business combination in August 2024, and a $0.3 million increase in payroll expenses, partially offset by a $0.6 million decrease in subcontractors and consultants expenses. General and administrative expenses increased by $5.8 million to $6.8 million (compared to $1.0 million in 2023), with $3.4 million attributable to one-time non-cash share-based compensation, $1.2 million in one-time professional services costs for legal, accounting, and other expenses directly associated with becoming a public company, and $0.9 million in increased payroll expenses. Additionally, in March 2025, the Company entered into an agreement to retire a promissory note through a combination of cash and share issuances, and completed the retirement of the promissory note on March 18, 2025.
• Financial Expenses: Financial expenses, net for 2024 were $3.9 million, compared to $0.4 million in 2023, an increase of $3.5 million. This increase was primarily driven by a one-time loss of $4.8 million upon entering the business combination , partially offset by a $1.2 million increase in revaluation income from financial instruments (warrants, promissory notes and ELOC).     
• Net Loss: Net loss for 2024 was $16.5 million, compared to $5.1 million in 2023. This increase was primarily driven by higher general and administrative expenses (including a significant increase in non-cash share-based compensation in the amount of $5.7 million), increased research and development investments, and one-time financial expenses of $4.8 million related to the Company's business combination and transition to a public entity.
