Frequently asked questions about NVL-330

What is NVL-330 used for?

NVL-330 is an investigational small molecule being developed for the treatment of locally advanced solid tumors. It is currently being studied in patients with advanced or metastatic HER2-altered non-small cell lung cancer (NSCLC) as part of the HEROEX-1 clinical trial.

What does NVL-330 target?

NVL-330 targets HER2, a protein that can drive tumor growth when altered. By targeting HER2, NVL-330 is designed to interfere with cancer cell signaling. It is being evaluated in patients with HER2-altered tumors, including those with advanced or metastatic NSCLC.

Who makes NVL-330?

NVL-330 is being developed by Nuvalent, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol NUVL. The company is conducting clinical trials to evaluate the safety and efficacy of NVL-330 in patients with HER2-altered solid tumors.

What phase is NVL-330 in?

NVL-330 is currently in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. The ongoing Phase 1 trial is recruiting patients to assess the drug's safety, tolerability, and preliminary activity.

What clinical trials is NVL-330 in?

NVL-330 is being studied in the HEROEX-1 trial, registered as NCT06521554. This Phase 1 study is recruiting approximately 200 patients with advanced or metastatic HER2-altered NSCLC and is being conducted in the United States, Australia, and Canada.

Is NVL-330 the same as HEROEX-1?

No, NVL-330 is the drug being studied, while HEROEX-1 is the name of the clinical trial evaluating it. The trial, identified as NCT06521554, is a Phase 1 study of NVL-330 in patients with advanced or metastatic HER2-altered NSCLC.
