Study of Circulating Tumour DNA (ctDNA) Kinetics in Immuno-oncology (IO-KIN)

Official Title

Study of Circulating Tumour DNA (ctDNA) Kinetics in Immuno-oncology: Intense Dynamic Monitoring of ctDNA in Advanced/Metastatic Head and Neck Squamous Cell Carcinoma (HNSCC) Patients Treated With Immune Checkpoint Inhibitors.

Summary:

This study aims to study the kinetics of ctDNA levels after the first dose of immune checkpoint inhibitor in patients with recurrent or metastatic head and neck cancer. This is an important study to understand the optimal timing for ctDNA quantitation for future studies in immunotherapy, though further validation would be needed in other tumour types. It may help standardize the most relevant blood collection time points so that patients will not be subjected to multiple blood draws at random time points in future liquid biopsy trials.

Trial Description

Primary Outcome:

  • To evaluate the change in kinetics of ctDNA changes in advanced/metastatic. HNSCC patients treated with immune checkpoint inhibitors (anti-PD-1 antibody).
Secondary Outcome:
  • To correlate the changes in ctDNA levels with progression free survival (PFS) and overall survival (OS).
  • To evaluate the optimal time-point to analyze ctDNA as a predictive marker of response to immune checkpoint inhibitors (anti-PD-1 antibody).
