Study summary

The goal of this ancillary clinical trial is to evaluated circulating DNA as a biomarker of residual disease after chemoradiotherapy for locally advanced head and neck squamous cell carninoma.

The main question it aims to answer is :

- Does circulating DNA (cDNA) be able to detect residual disease 3 months after the end of chemoradiotherapy ? Researchers will compare detection of cDNA at 3-months and objective response (clinical and radiological).

Participants will :

  • be included in the main study (Neck-TAR)
  • have a blood sample 1 and 3-month after the end of treatment

Eligibility criteria

Selection Criteria:

  • Patient included in NeckTAR study
  • Written signed for NeckTAR-IN study
  • Affiliation to the French social security system
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

    The intervention consist in blood samples (18mL) collected 1 and 3-months after the end of chemoradiotherapy

What researchers measure

Primary outcomes

  1. cDNA detection and objective response 3 months after the end of chemoradiotherapy

    The detection or non detection of cDNA after treatment will be compared with the objective response (complete response versus progression/stability/partial response)

    Time frame: 3 months after chemoradiotherapy

Secondary outcomes

  1. cDNA detection and objective response one month after the end of chemoradiotherapy

    The detection or non detection of cDNA after treatment will be compared with the objective response (complete response versus progression/stability/partial response)

    Time frame: 1 month after the end of chemoradiotherapy

  2. Overall survival

    The overall survival is defined as the time between the date of inclusion and the date of death from any cause.

    Time frame: At the end of the main study (27 months after the end of treatment)

  3. Progression-free survival

    The progression-free survival is defined as the time between the date of inclusion and the date of the first progression of the disease (clinical or radiological) or death from any cause.

    Time frame: At the end of the main study (27 months after the end of treatment)

  4. cDNA kinetic

    cDNA detection at 1 and 3 months after the end of chemoradiotherapy

    Time frame: 1- and 3-month after the end of chemoradiotherapy

  5. Concordance of mutational profiles and HPV-HR genotypes between primary tumor, ctDNA at diagnosis and ctDNA

    This will be evaluated according to the mutational profile determined by NGS at each timepoint

    Time frame: 1- and 3-months after the end of chemoradiotherapy

  6. Determining the most frequent mutations.

    That will be evaluated by analysing the results of NGS (among the 194 genes in our panel)

    Time frame: 3-months after the end of chemoradiotherapy

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Sep 11, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
