- NCT05307939
- Lead Sponsor
- Memorial Sloan Kettering Cancer Center
- Brief Summary
This study will look at whether monitoring HPV ctDNA levels is an effective way to detect cancer relapse risk in people with HPV-OPC. All participants will have recently had surgery to treat their disease, or they will be scheduled to have this surgery.
In Arm A the researchers will see whether monitoring participants' HPV ctDNA levels can safely identify patients who do not need radiation therapy (RT) after surgery and whose RT can be delayed until their HPV ctDNA levels become detectable.
In Arm B, the researchers will see whether patients who usually need 6-6.5 weeks of CRT can be selected by HPV ctDNA to receive 3 weeks of CRT.

Group Intervention Description Screening, active surveillance, and treatment (Arm A) HPV ctDNA Assay Participants who meet criteria for the treatment phase (a post-operative HPV ctDNA which rose from initial undetectable to meet HPV16 ctDNA criteria and have no clinical or radiographic evidence of gross disease) will undergo delayed standard of care adjuvant radiation (50-60 Gy administered in 1.8-2 Gy fractions) based on the patient's initial pathology. Treatment will be initiated within 4 weeks of a NavDx result. Subjects will undergo FDG PET/CT simulation and standard radiation treatment planning and this FDG PET/CT will also be utilized to rule out distant metastases. Diagnostic FDG PET/CT fusion is also allowed for treatment planning and to rule out distant metastases. Non-therapeutic assessments will be completed. Screening and deescalated treatment (Arm B) Chemoradiation (Arm B) Participants who meet criteria for the de-escalated treatment phase (Arm B) will undergo adjuvant radiation (30 Gy administered in 2 Gy fractions) with concurrent chemotherapy. They will undergo FDG PET/CT simulation and standard radiation treatment planning and this FDG PET/CT will also be utilized to rule out distant metastases.
