About this trial

This is a phase II clinical trial. The purpose of this study is to determine the feasibility of deescalating chemoradiation treatment based on mid-treatment tumor response determined by rapid nodal shrinkage and clearance of circulating HPV plasma tumor DNA . The primary objective of this study is to evaluate progression-free survival at 2 years.

Eligibility criteria

Qualifiers

Pathologically (histologically or cytologically) proven diagnosis of squamous cell carcinoma of the oropharynx, which include the sites tonsil, base of tongue, soft palate, or posterior oropharyngeal wall. Histologic variants will be included (papillary squamous cell carcinoma and basaloid squamous cell carcinoma). Cytologic diagnosis from a cervical lymph node is sufficient in the presence of clinical evidence of a primary tumor in the oropharynx.

If the primary site is biopsied, Patient's tissue must be positive for p16 by immunohistochemical staining (>70% staining). Fine needle aspiration (FNA) biopsy specimens may be used as the sole diagnostic tissue if formalin-fixed paraffin-embedded cell block material is not available for p16 immunohistochemistry.

Patients must have detectable HPV ctDNA Score Report at Screening or have a detectable baseline HPV ctDNA Score Report (Naveris test) if no primary site is biopsied. Must have detectable screening plasma HPV DNA (also referred to as ctHPV DNA).

Fiberoptic exam with laryngopharyngoscopy (mirror and/or fiberoptic and/or direct procedure) within 8 weeks prior to registration.

Disqualifiers

Missing or undetectable baseline plasma HPV DNA level

Cancers considered to be from an oral cavity site (oral tongue, floor of mouth, alveolar ridge, buccal or lip), or the nasopharynx, hypopharynx, or larynx, even if p16 positive;

Carcinoma of the neck of unknown primary site origin (even if p16 positive);

Distant metastasis or adenopathy below the clavicles;
