Grand Cayman, Cayman Islands, Nov. 12, 2025 (GLOBE NEWSWIRE) — Silexion Therapeutics Corp. (NASDAQ: SLXN) (“Silexion” or the “Company”), a clinical-stage biotechnology company developing RNA interference (RNAi) therapies for KRAS-driven cancers, today reported its financial results for the third quarter ended September 30, 2025, and provided an update on recent business developments.

Recent Milestones & Business Highlights:

Clinical Trial Preparation On Track: Silexion continues to advance operational readiness for its planned Phase 2/3 clinical trials of SIL204, with toxicology studies progressing as planned. Regulatory submissions are expected to be filed with the Israel Ministry of Health in Q4 2025 and in Germany and in the European Union in Q1 2026, with clinical trial initiation anticipated in the first half of 2026.

Strong Preclinical Results Across Multiple Cancer Types: The Company continues to accumulate positive efficacy preclinical data in various KRAS-driven cancers, further supporting the potential of SIL204 as a platform technology for these oncogene-driven cancers. Silexion announced that SIL204 successfully killed cancer cells across five different cancer types with very high effectiveness. The drug worked against eight different cancer-causing mutations, including the most common ones found in pancreatic, lung, and colorectal cancers. Importantly, this included the first evidence that SIL204 works in gastric (stomach) cancer. These results demonstrate SIL204’s potential to treat a wide range of KRAS-driven cancers with a single therapy.

CRO Partnership to Support  the Phase 2/3 Trials: In September 2025, Silexion announced that it had selected AMS Advanced Medical Services GmbH as its contract research organization (CRO) to support the upcoming Phase 2/3 clinical trials for SIL204. AMS brings over 28 years of oncology clinical development and regulatory experience, including management of Phase 3 trials in pancreatic cancer. This partnership covers regulatory strategy, clinical trial design, and data management to advance Silexion’s dual-route administration approach combining intratumoral and systemic delivery methods.

Capital Raises Significantly Strengthen Balance Sheet: During the third quarter, Silexion completed a public offering and received additional proceeds from warrant exercises, raising approximately $9.5 million in gross proceeds. These transactions, together with cost discipline and balance-sheet optimization, increased cash and cash equivalents to $9.2 million as of September 30, 2025, up from $3.5 million at June 30, 2025. In light of the foregoing transactions, together with a partial promissory note conversion, the Company’s shareholders’ equity rose to $7.0 million, a substantial improvement from a capital deficiency of $4.0 million at year-end 2024.

Regaining Nasdaq Listing Compliance: Following the Nasdaq hearings panel decision in July 2025, Silexion successfully demonstrated compliance with Nasdaq’s minimum bid price and shareholders’ equity requirements. On September 23, 2025, Nasdaq confirmed that the Company had regained full compliance with Listing Rules 5550(a)(2) and 5550(b)(1), securing continued listing on the Nasdaq Capital Market.

Ilan Hadar, Chairman and Chief Executive Officer of Silexion, commented: “The third quarter marked a period of strong scientific progress and continued operational momentum for Silexion. With new preclinical data demonstrating SIL204’s exceptional efficacy across a broad range of KRAS mutations and multiple cancer types, we are entering the next phase of development with great confidence. The selection of a CRO partner and the successful completion of additional financing further strengthen our readiness to initiate Phase 2/3 clinical trials in the first half of 2026. Our focus now is on completing regulatory submissions in Israel and the EU and advancing toward the clinic with the same precision and discipline that have defined our progress to date.”

Mirit Horenshtein Hadar, Chief Financial Officer of Silexion, added: “Our financial results for the third quarter reflect meaningful improvement in both our balance sheet and operating efficiency. The successful $9.5 million of financings completed during the quarter significantly increased our cash position and shareholders’ equity, contributing to maintaining our Nasdaq listing. We believe our strengthened capital structure and financial discipline provide a solid foundation to support us as we advance towards our upcoming regulatory and clinical milestones.”

Financial Results for the Three Months Ended September 30, 2025:

• Research and Development (R&D) Expenses for the three months ended September 30, 2025, were $2.2 million, compared to $3.2 million for the same period in 2024, a decrease of 31.3%, primarily due to the absence in the current year period of $2.4 million in non-cash share-based compensation expenses recorded in the prior-year period (associated with grants issued during the August 2024 Business Combination), partially offset by increased subcontractor costs of approximately $1.3 million related to API manufacturing activities and formulation development as the development program advances.
• General and Administrative (G&A) Expenses for the three months ended September 30, 2025, were $1.1 million, compared to $4.8 million for the same period in 2024, a decrease of 77.1%, mainly attributable to the absence of $3.4 million in non-cash share-based compensation expenses associated with grants issued during the August 2024 Business Combination.
• Net loss for the three months ended September 30, 2025, was $3.3 million, or ($2.88) per share, compared to a net loss of $11.9 million, or ($274.25) per share, for the same period in 2024, representing a decrease of approximately 72.3%. The improvement was mainly attributable to the absence of significant one-time costs and expenses related to  the August 2024 Business Combination and the Company’s transition to a public company, including share-based compensation, transaction, and financial expenses.

Financial Results for the Nine Months Ended September 30, 2025:

• Research and Development (R&D) Expenses for the nine months ended September 30, 2025, were $3.8 million, compared to $4.9 million for the same period in 2024, a decrease of 22.4%, primarily due to the absence of non-cash share-based compensation expenses (associated with grants issued during the August 2024 Business Combination), partially offset by higher subcontractor costs related to API manufacturing activities and formulation development as the development program advanced.
• General and Administrative (G&A) Expenses for the nine months ended September 30, 2025, were $3.5 million, compared to $5.7 million for the same period in 2024, a decrease of 38.6%, mainly reflecting the absence of non-cash share-based compensation expenses and transaction costs associated with the August 2024 Business Combination.This decrease was partially offset by higher professional services costs including director compensation, legal and other expenses associated with the transition to a public company subsequent to the Closing of the Business Combination, and more.
• Net loss for the nine months ended September 30, 2025, was $7.5 million, or ($10.36) per share, compared to a net loss of $14.8 million, or ($754.85) per share, for the same period in 2024, representing a decrease of 49.3%. The reduction was mainly due to lower share-based compensation expenses and the absence of significant one-time costs and expenses related to the August 2024 Business Combination, including transaction and financial expenses.

Balance Sheet Highlights:

• As of September 30, 2025, Silexion had cash and cash equivalents of $9.2 million, compared to $1.2 million as of December 31, 2024. This significant increase reflects the successful completion of public offerings and warrant exercises during 2025, which substantially strengthened the Company’s balance sheet and support its continued advancement toward regulatory submissions and Phase 2/3 clinical trial initiation.
