Adlai Nortye Announces First Patient Enrolled in Global Phase 1 Trial of Pan-RAS (ON) Inhibitor AN9025 for Solid Tumors Harboring RAS Mutations

SINGAPORE and NORTH BRUNSWICK, N.J. and HANGZHOU, China, February 12, 2026 – Adlai Nortye Ltd. (NASDAQ: ANL) (the “Company” or “Adlai Nortye”), a clinical-stage biotechnology company focused on the development of innovative cancer therapies, today announced that the first patient has been dosed in the United States in early February in its ongoing Phase 1 clinical trial of AN9025, a pan-RAS (ON) inhibitor.

The Phase 1 study is a first-in-human, multicenter, open-label trial designed to evaluate the safety, tolerability, pharmacokinetics and anti-tumor activity of AN9025 in patients with advanced or metastatic solid tumors harboring RAS mutations. This trial is being conducted by Adlai Nortye in collaboration with Jiangsu Aosaikang Pharmaceutical Co. Ltd. (“ASK Pharm”) as a multi-regional clinical trial (“MRCT”) pursuant to a license agreement , under which Adlai Nortye retains ex-China rights to AN9025, while ASK Pharm holds rights in mainland China, Hong Kong and Macao.

“Dosing the first U.S. patient with AN9025, our wholly in-house discovered, oral pan-RAS(ON) inhibitor with best-in-class potential, is a significant milestone,” said Dr. Archie Tse, Head of Research and Development at Adlai Nortye. “This achievement advances our clinical strategy to evaluate AN9025 across multiple RAS-mutant solid tumors. We look forward to efficiently progressing its global clinical development and generating meaningful data to support its future advancement.”

About AN9025

AN9025 is an oral small molecule pan-RAS(ON) inhibitor with best-in-class potential, designed to target a broad spectrum of RAS mutations across various tumor types. Preclinical studies have demonstrated that AN9025 effectively inhibits RAS-mutant cancers with potent and durable efficacy, including pancreatic, lung, and colorectal adenocarcinomas, and shows comparable or superior results relative to a benchmark agent of the same class.

About Adlai Nortye

Adlai Nortye (NASDAQ: ANL) is a global clinical-stage company at the forefront of discovering and developing innovative cancer therapies. Leveraging our dual R&D presence in the U.S. and China, we are building a robust pipeline of drug candidates focused on two key areas where we believe we can make a significant difference. (1) Next-generation cancer immunotherapies: our candidates, AN8025 (a tri-functional fusion protein of αPD-L1 x CD86 variant x LAG3 variant), a T-cell and antigen-presenting cell modulator, and AN4005 (a first-in-class oral small-molecule PD-L1 inhibitor), are designed to activate cancer immunity in novel ways. (2) RAS-targeting therapies: we are tackling RAS-driven cancers with AN9025, an oral pan-RAS(ON) inhibitor, and AN4035, a CEACAM5-targeting ADC delivering a potent pan-RAS(ON) inhibitor directly to tumors.
