About this study

This trial is testing a treatment called JZP815 in adults with advanced or metastatic solid tumors that have changes in the MAPK pathway. The goal is to learn about its safety, how it works in the body (pharmacokinetics), and if it can kill cancer cells (antitumor activity).

Based on ClinicalTrials.gov records.
