Frequently asked questions about ALX2004

What is ALX2004 used for in NSCLC?

ALX2004 is an investigational small molecule being developed for advanced non-small cell lung cancer (NSCLC). It is currently in Phase 1 clinical development and is not yet approved by the FDA. The drug is being studied in patients with advanced or metastatic selected solid tumors, including NSCLC.

What does ALX2004 target?

ALX2004 targets EGFR, the epidermal growth factor receptor. By targeting EGFR, the drug is designed to interfere with signaling pathways that can drive tumor growth. This mechanism is being evaluated in a Phase 1 clinical trial for advanced solid tumors, including NSCLC.

Who makes ALX2004?

ALX2004 is being developed by ALX Oncology Holdings Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol ALXO. The company is conducting a first-in-human study of ALX2004 in patients with advanced or metastatic selected solid tumors.

What phase is ALX2004 in?

ALX2004 is in Phase 1 clinical development. It is an investigational drug and has not received FDA approval. The ongoing Phase 1 trial is recruiting participants in the United States to evaluate the drug's safety and tolerability in advanced solid tumors.

What clinical trials is ALX2004 in?

ALX2004 is being studied in a single Phase 1 clinical trial with the identifier NCT07085091. This first-in-human study is recruiting 170 participants with advanced or metastatic solid tumors, including NSCLC, head and neck cancer, colorectal cancer, and esophageal squamous cell carcinoma. The trial is being conducted in the United States.

Is ALX2004 the same as other EGFR inhibitors?

ALX2004 is a distinct investigational small molecule targeting EGFR. While it shares a molecular target with other EGFR inhibitors, it is a separate drug candidate developed by ALX Oncology. No alternative names for ALX2004 have been disclosed in the clinical trial information.
