ALX Oncology Holdings Inc. has announced the initiation of its Phase 1 clinical development program for ALX2004, following clearance of its Investigational New Drug $(IND.AU)$ application by the U.S. Food and Drug Administration in April 2025. ALX2004, a novel EGFR-targeted antibody-drug conjugate, is set to enter Phase 1 trials in mid-2025. The trial will focus on dose escalation in patients with EGFR-expressing solid tumors, including non-small cell lung cancer, colorectal cancer, head and neck squamous cell carcinoma, and esophageal squamous cell carcinoma. Initial safety data from the study is anticipated in the first half of 2026. ALX Oncology will provide further details on its clinical development plans and preclinical data in a webcast event.
