Melanoma Clinical Trial
Correlating Early FDG PET/CT and ctDNA in Immune Checkpoint Inhibitor (ICI)-Treated Melanoma Patients
Summary
The purpose of this research study is to determine if analysis of PET/CT scans and testing of blood samples in people with melanoma that has spread in their body can help researchers determine which patients are more or less likely to respond to immunotherapy and are more or less likely to have side effects. 24 participants will be enrolled and be on study until approximately 4 weeks after their first dose of Immune Checkpoint Inhibitor therapy.
Full Description
This is a pilot, prospective, observational study to estimate the degree to which baseline and early interval 18F-FDG PET/CT imaging within 3-4 weeks of ICI therapy initiation can accurately correlate with ctDNA level trends, predict clinical response, onset of immune-related adverse events, and survival outcomes in advanced stage melanoma patients.
Primary Objective
• To determine if early interval response assessment with 18F-FDG PET/CT during initial treatment with ICI therapy at 3-4 weeks correlates with ctDNA level changes in advanced melanoma patients.
Secondary Objectives
To determine if early interval response assessment with 18F-FDG PET/CT during initial treatment with ICI therapy at 3-4 weeks predicts clinical efficacy at standard disease assessment time points in advanced melanoma patients.
To assess if early interval response assessment with 18F-FDG PET/CT predicts development of clinical irAEs in advanced melanoma patients.
To assess if early interval response assessment with 18F-FDG PET/CT and ctDNA level predicts progression-free survival (PFS) in advanced melanoma patients.
To assess if early interval response assessment with 18F-FDG PET/CT and ctDNA level predicts overall survival (OS) in advanced melanoma patients.
