GenFleet Therapeutics Issues Clarification on Intellectual Property Status of GFH276 Pan RAS Inhibitor

Key Highlights for Investors

• GenFleet Therapeutics (Shanghai) Inc. has addressed recent market concerns regarding potential intellectual property disputes related to RAS inhibitors.
• The company affirms that its Pan RAS inhibitor, GFH276, is independently developed and based on fully original, proprietary intellectual property, with no exposure to ongoing patent or trade secret disputes cited in the sector.
• GenFleet has secured a global patent portfolio for its Pan RAS inhibitor program. The core patent covering the compound structure of GFH276 was officially published on March 6, 2025, and the protection period is projected to extend until 2044.
• GFH276 targets both wild-type and mutant RAS proteins, including the most prevalent KRAS mutations (G12C, G12D, G12V, etc.). Preclinical data indicates dose-dependent anti-tumor activity and the ability to drive tumor regression in multiple KRAS mutant tumor models.
• The company asserts that GFH276 may outperform mainstream SIIP-based KRAS inhibitors by overcoming adaptive and acquired resistance, a key challenge in the oncology treatment landscape.

Details and Implications for Shareholders

In response to reports that Revolution Medicines Inc. had issued correspondence to a third party regarding patent and trade secret disputes on RAS inhibitors, GenFleet Therapeutics has publicly clarified that:

• None of the products, entities, or disputed matters referenced by Revolution Medicines are related in any way to GenFleet or GFH276.
• GenFleet’s GFH276 has been developed without any overlap or exposure to the disputes referenced, which removes a significant risk factor for potential investors and partners.
• The company’s robust international patent protection until 2044 provides a strong competitive barrier and may enhance the valuation of the GFH276 program.

About GFH276

GFH276 is an oral, novel small-molecule Pan RAS (ON) inhibitor that hijacks Cyclophilin A (Cyp A) to specifically target active, GTP-bound RAS proteins across a wide range of wild-type and mutant forms. This includes the most clinically relevant KRAS mutants, which are known drivers of many cancers and have historically been difficult to target.

Preclinical studies demonstrate that GFH276 exhibits dose-dependent anti-tumor activity, causing regression in multiple models of KRAS mutant tumors—a potential breakthrough in cancer therapy. Furthermore, the compound may have the potential to outperform existing SIIP (switch II pocket)-based KRAS inhibitors by overcoming adaptive and acquired resistance mechanisms that limit the effectiveness of current treatments.

Potential Share Price Impact

• De-Risking Update: The statement significantly de-risks the GFH276 program by clarifying that GenFleet is not involved in any ongoing patent or trade secret disputes in the RAS inhibitor space. This removes a major overhang that could negatively impact investor sentiment and the company’s valuation.
• Patent Strength: The confirmation of a long patent life (protection until 2044) supports the commercial viability and exclusivity of GFH276.
• Pipeline Potential: Positive preclinical data and the possibility of outperforming existing therapies may position GFH276 as a best-in-class asset, which could attract partnership interest or increase the company’s market value as the program advances.

Risk Factors and Forward-Looking Statements

Investors should note that the development and commercialization of GFH276 is subject to significant uncertainties. The company cannot guarantee successful development or ultimate market approval of GFH276. Forward-looking statements in the announcement reflect management’s current beliefs and expectations, but actual results may differ due to market, policy, and R&D uncertainties.
