SURVEILLE-HPV: Evaluation of HPV16 Circulating DNA as Biomarker to Detect the Recurrence, in Order to Improve Post Therapeutic Surveillance of HPV16-driven Oropharyngeal Cancers (SURVEILLE-HPV)
Oropharynx Squamous Cell Carcinoma
About this trial
This is an interventional diagnostic trial for Oropharynx Squamous Cell Carcinoma focused on measuring HPV16, CtDNA
Eligibility Criteria
Inclusion Criteria:
- Patient aged 18 years or over
- Patient with p16 positive Oropharyngeal squamous cell carcinoma (OPSCC)
- Clinical stage T1-4, N0-3, M0 (stages I-III)
- Any tobacco status
- Life expectancy greater than 36 months
- Positive HPV16 Ct-DNA measured before curative anticancer treatment
- Treated by any curative treatment
Complete response at 3 months after end of treatment, which means:
- Undetectable HPV16 Ct-DNA and no residual disease on imaging (group A) or
- Undetectable HPV16 Ct-DNA and suspicious imaging but persistent disease excluded by either biopsy or repeated imaging (group B1) or
- Positive HPV16 Ct-DNA and no residual disease on imaging but negative HPV16 Ct-DNA on the subsequent assessment. This second test will be done 1-2 months after the first one (group C1).
- Patient must be affiliated to a Social Security System (or equivalent)
- Patients must have signed a written informed consent form prior to any trial specific procedures. If the patient is physically unable to give his/her written consent, a trusted person of his/her choice, note related to the investigator or the sponsor, can confirm in writing the patient's consent.
Exclusion Criteria:
- Uncontrolled intercurrent illness that would limit compliance with study requirements.
- Active invasive malignancy within 3 years of inclusion except for non-invasive malignancies such as non-melanomatous carcinoma of the skin or ductal carcinoma in situ of the breast that has/have been surgically cured.
- Any other HPV induced cancer within 5 years
- Any condition that may jeopardize the patient participation as well as non-contraception for male and female with child-bearing potential, pregnancy or breast-feeding
- Patient unwilling or unable to comply with the study protocol and follow-up schedule.
- Participation in another clinical trial with an investigational medical product during the last 30 days prior to the inclusion and during the present study (except if patient is included in the control arm, with placebo or with a product that have a marketed authorization, used as per the summary of product characteristics (SmPC) for the given indication).
- Patient deprived of liberty or placed under protective custody or guardianship.

Arms of the Study
Arm 1
Arm 2
No Intervention
Experimental
Standard follow-up monitoring (16 visits over 5 years)
Lightened follow-up visits frequency (9 visits over 5 years), with HPV16 Ct-DNA dosing
Patients enrolled in the control arm will be monitored according to SFORL guidelines. Physical Examination (PE) will be carried out: - every 2 months the 1st year, every 3 months the 2nd year, every 4 months the 3rd year, every 6 months at 4 and 5 years. Annual chest CT scan will be performed for current smokers & for those who have quit smoking less than 15 years ago.
Physical Examinations (with HPV16 Ct-DNA dosing) planned at Months 4,8,12,18,24,30,36,48,60 post treatment. Annual chest CT scan will be performed for current smokers & for those who have quit smoking less than 15 years ago. Any patient with a normal PE but positive HPV16 ct-DNA test during follow-up period will require a confirmation test ~1-2 months later. If HPV16 ct-DNA positivity is confirmed, an H&N MRI /PET-CT will be performed. Then: If MRI and PET-CT are negative, the patient will be examined every 2 months (PE and HPV16 Ct-DNA dosing) and MRI/PET-CT will be repeated every 4-6 months, until HPV16 Ct-DNA becomes undetectable. If MRI and/or PET-CT is positive, the patient will get a biopsy to confirm disease recurrence. Once confirmed, the patient will have the necessary care, as per local practices, but will continue to be followed up within this study up to 5 years after treatment.
