Note: This drug is in the pipeline and is planning to open Phase 1 clinical trials in mid-2025.
ALX Oncology (ALXO) has received FDA clearance for its Investigational New Drug (IND) application for ALX2004, a potential first-in-class antibody-drug conjugate (ADC) for treating EGFR-expressing solid tumors. The company plans to initiate Phase 1 clinical trials in mid-2025, with initial safety data expected in 1H 2026.
ALX2004, developed entirely in-house using the company’s proprietary linker-payload platform, targets EGFR – a transmembrane protein overexpressed in various cancers including breast, colorectal, head and neck, and non-small cell lung cancer. The drug is designed to optimize targeted delivery of chemotherapy to tumor cells while minimizing systemic toxicity.
The molecule features an engineered antibody backbone for optimized anti-EGFR activity, enhanced stability linker, and a proprietary topoisomerase I payload capable of generating an enhanced bystander effect. An R&D call focused on ALX2004 is planned for Q2 2025. Read more.
