Study of NVL-330 for HER2-altered NSCLC

This study is testing a new oral tablet called NVL-330 for people with advanced or metastatic non-small cell lung cancer (NSCLC) that has a specific change in the HER2 gene. Researchers want to find the safest and most effective dose of NVL-330. They will also look at how well NVL-330 works against the cancer. To join, you must be at least 18 years old and have NSCLC with a documented HER2 alteration. The study aims to enroll about 200 participants. The study is currently recruiting, but the exact status is unclear.

Study design
This is a Phase 1a/1b study, which means it's an early-stage trial to test safety and find the right dose. It is designed to enroll a set number of participants per dose level.
What's involved
Not specified in the trial record.
Compensation
Not stated in the trial record.
Follow-up
Your safety will be monitored for at least 30 days after your last dose of NVL-330.
