Using liquid biopsy to predict responses to immunotherapy in metastatic lung cancer

LIquid Biopsy to prEdict Responses To First-line immunotherapY in Metastatic Non-small Cell LUNG Cancer

Not applicable Interventional Institut Curie · NCT04790682

This study is testing if measuring tumor DNA in the blood can help predict how well new immunotherapy treatments work for people with advanced lung cancer who haven't started treatment yet.

What this trial studies

This study aims to evaluate the predictive value of circulating tumor DNA (ctDNA) levels in patients with metastatic non-small cell lung cancer (NSCLC) who are treatment-naïve and eligible for first-line immunotherapy. Patients will undergo next-generation sequencing (NGS) analysis on tumor tissue to identify mutations, and only those with at least one mutation will be enrolled. Blood samples will be collected at various intervals to monitor ctDNA levels and assess treatment response using RECIST 1.1 criteria. The study will also include routine imaging to evaluate disease progression.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with histologically-proven metastatic NSCLC who have not received prior treatment and are eligible for first-line immunotherapy.

Not a fit: Patients with ALK or EGFR gene alterations or those who are not treatment-naïve may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment strategies for patients with metastatic lung cancer, improving their response to immunotherapy.

How similar studies have performed: Other studies have shown promise in using liquid biopsies for monitoring treatment responses in various cancers, suggesting this approach may be effective.
