Measuring Cell-Free DNA (cfDNA) Levels in People With Follicular Lymphoma (NCT04468841)

An Exploratory Study to Correlate the Level of Cell-free DNA With Response to First-line Treatment in Patients With Follicular Lymphoma

🔵 Active, Not Recruiting Phase1 📋 Clinical Research Protocol Sponsor: Memorial Sloan Kettering Cancer Center

🩺 Plain-English Summary (8th-Grade Level)

The researchers are doing this study to measure and test cell-free DNA (cfDNA) in the blood before, during, and after first-line treatment for follicular lymphoma. They will look at whether cfDNA levels are related to a person's response to the usual first-line treatment for follicular lymphoma. Researchers also want to understand how different genetic changes in follicular lymphoma relate to a person's response to the usual first-line treatment.
