Measuring cell-free DNA levels in patients with follicular lymphoma

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

Phase 1 Interventional Memorial Sloan Kettering Cancer Center · NCT04468841

What this trial studies

This study aims to measure and analyze cell-free DNA (cfDNA) in the blood of individuals diagnosed with follicular lymphoma before, during, and after their first-line treatment. Researchers will assess whether cfDNA levels correlate with the patients' responses to standard treatment and explore the relationship between genetic changes in the lymphoma and treatment outcomes. The study involves collecting blood samples at various stages of treatment and comparing cfDNA assay results with traditional response assessment methods like PET-CT scans.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18 and older with histologically confirmed follicular lymphoma grade 1-3a who are starting first-line treatment.

Not a fit: Patients who are receiving second or greater lines of therapy will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more accurate method for monitoring treatment response in patients with follicular lymphoma.

How similar studies have performed: Other studies have shown promise in using cfDNA as a biomarker for treatment response, indicating that this approach is gaining traction in clinical research.
