Adlai Nortye doses first patient in weekly-dosing arm of AN9025 Phase 1 trial

The company said both once-weekly and once-daily dosing arms of its pan-RAS(ON) inhibitor study are now enrolling, with early data expected in 1H27.

Adlai Nortye Ltd. (NASDAQ: ANL) announced on July 16, 2026 that the first patient has been dosed in the United States in the intermittent weekly dosing (QW) arm of the ongoing Phase 1 clinical trial of AN9025, a pan-RAS(ON) inhibitor.1

Dr. Archie Tse, the company's President and Head of Research and Development, called the U.S. dosing event a significant step in evaluating AN9025 through a differentiated schedule, and said the company's preclinical data suggest that weekly dosing may allow for a wider therapeutic window, potentially supporting higher doses or better tolerability and combinability by giving normal tissue recovery time while still suppressing tumor RAS signaling.1 He added that the company plans to share initial Phase 1 dose escalation data in 1H27 from the QD arm, with a potential early look at the QW arm.1

The trial is described in the release as a first-in-human, open-label study across multiple centers, designed to assess safety, tolerability, pharmacokinetics, and anti-tumor effects of AN9025 in patients with advanced or metastatic solid tumors carrying RAS mutations.1 It is being run as a multi-regional clinical trial conducted jointly with Jiangsu Aosaikang Pharmaceutical Co. Ltd. under a license agreement, with Adlai Nortye holding rights outside China and ASK Pharm holding rights in mainland China, Hong Kong, and Macao.1 With this milestone, both the once-daily and once-weekly dose escalation arms are now enrolling patients.1

According to the release, AN9025 is an oral small molecule designed to inhibit a broad range of RAS mutations, and preclinical work has shown it suppresses RAS-mutant cancers including pancreatic, lung, and colorectal tumors, with results the company describes as comparable to or better than an existing benchmark compound in its class.1
