Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with advanced ROS1-positive NSCLC or other solid tumors who have specific treatment histories.

Probably not a fit

Patients with cancers that have known oncogenic driver alterations other than ROS1 may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial is a Phase 1/2 study designed to assess the safety, tolerability, and antitumor activity of NVL-520 in patients with advanced solid tumors that have a ROS1 rearrangement. The trial will begin with a dose escalation phase to determine the recommended phase 2 dose and maximum tolerated dose of NVL-520. Following this, the Phase 2 portion will evaluate the objective response rate and other efficacy measures in various cohorts of patients with ROS1-positive non-small cell lung cancer (NSCLC) and other solid tumors. The study aims to provide insights into the effectiveness of NVL-520 in treating these specific cancer types.

Why it matters

Potential benefit: If successful, this treatment could offer a new therapeutic option for patients with advanced ROS1-positive solid tumors.

How similar studies have gone: Other studies targeting ROS1 rearrangements have shown promise, indicating that this approach is supported by prior research.
