A Single Arm Phase II Trial Evaluating Selective Adjuvant Therapy for HPV-mediated Oropharynx SCCs Based on Residual Circulating Tumor DNA Levels (SAVAL)

Summary

Patients with human papillomavirus (HPV)-related oropharyngeal cancer generally have favorable outcomes and how well they do depends on the specific details about the patient and their cancer. How well they do isn't as related to the kinds of treatment they get. However, there are significant side effects for the various types of treatments they may get. Because these patients generally have favorable outcomes no matter the kind of treatment, reducing side effects should be a priority when choosing their treatment. The goal of this clinical research study is to evaluate whether a new blood test called a Circulating Tumor DNA test (ctDNA test) can decrease the number of people that require radiation after surgery. This blood test is often elevated in people when they are diagnosed with head and neck cancer. There are studies that show that cancer most often returns when this blood test is positive after treatment. This study will test patients' blood before and after surgery. In cases where the test is negative after surgery, people on the study will not receive radiation unless they are considered high risk based on surgery findings. The hope is that radiation and its potential side effects can be limited to only people that need the treatment.

Interventions

• Other
  Experimental Observation

  Patients on the experimental arm will be under observation only.

• Other
  Observation per Standard of Care

  The low-risk group of patients will be observed per standard of care.

• Radiation
  Adjuvant Treatment per Standard of Care

  The high-risk group of patients will receive adjuvant treatment per standard of care (Radiation with or without chemotherapy)

• Diagnostic Test
  Circulating Tumor DNA test (ctDNA test)

  Blood test for diagnostic and surveillance purposes measuring expression of Cell free HPV tumor DNA (ctDNA) in the blood. Patients will undergo ctDNA within 90 days pre-transoral robotic surgery(TORS), 2-14 days post TORS, then every 3 months (except for at 21 months) for 2 year post completion of initial therapy or salvage therapy.
