Recruiting now · Phase 2

Conditions studied: HPV-Associated Oropharyngeal Squamous Cell Carcinoma, HPV Positive Oropharyngeal Squamous Cell Carcinoma, HPV-Mediated (P16-Positive) Oropharyngeal Carcinoma by AJCC V8 Stage, HPV-Related Squamous Cell Carcinoma, Clinical Stage III HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8, Pathologic Stage III HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8, Clinical Stage II HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8, Pathologic Stage II HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8, Clinical Stage I HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8, Pathologic Stage I HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8, HPV-Mediated (P16-Positive) Oropharyngeal Carcinoma by AJCC V8 Clinical Stage, HPV-Mediated (P16-Positive) Oropharyngeal Carcinoma by AJCC V8 Pathologic Stage

In brief

This research is being conducted to understand if treatment can be tailored for participants with HPV-related oropharynx cancers using both clinical features (stage of the tumor, smoking status) combined with an investigational HPV blood test. The names of the test and treatments involved in this study are: * NavDx® HPV ctDNA testing (HPV blood test) * Radiation therapy * Chemotherapy: Cisplatin, or Carboplatin and Paclitaxel (not all participants receive any or all of these agents)

You may qualify if…

Participants must meet the following eligibility criteria at the time of screening to be eligible to participate in the study:
Subject must have histologically or cytologically confirmed, stage I, II, or III (N3 disease excluded), HPV associated oropharyngeal (tongue base or tonsil) squamous cell carcinoma, as defined by 2017 American Joint Committee on Cancer (AJCC), 8th edition staging.
- Patients with HPV-associated disease of unknown primary (cT0) are eligible
HPV status should be confirmed on tissue biopsy or cytologic sample by any of the following:
Immunohistochemical staining for p16 with ≥70% expression
Confirmatory DNA testing (PCR or ISH) for high-risk subtype
Willing to provide blood and tissue from a diagnostic biopsy and blood samples before, during, and after treatment.
Detectable HPV ctDNA blood sample at baseline, prior to treatment, using the NavDx® assay that detects HPV subtype 16
Age 22 years or older
ECOG performance status ≤ 2
Participants should have adequate organ and marrow function if they are to receive chemotherapy (cisplatin, or carboplatin and paclitaxel) with radiation concurrently as determined by standard institutional guidelines and investigator preference (parameters suggested below).
absolute neutrophil count (ANC) ≥ 1000
platelet count ≥ 100,000
total bilirubin of 1.5 or less
creatinine of 1.6 or less (or a CrCl ≥50 mL/min) per institutional standards.
Planning to receive non-surgical management for HPV+ oropharyngeal cancer
Ability to understand and the willingness to sign a written informed consent document.
Women of childbearing potential must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 72 hours prior to the start of (chemo)radiation therapy. "Women of childbearing potential (WOCBP)" is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) or who is not postmenopausal. Menopause is defined clinically as 12 months of amenorrhea in a woman over 45 in the absence of other biological or physiological causes. In addition, women under the age of 55 must have a documented serum follicle stimulating hormone (FSH) level above 40 mIU/mL.
Men who are sexually active with WOCBP must agree to use any contraceptive method with a failure rate of less than 1% per year. Men who are sexually active with WOCBP will be instructed to adhere to contraception for a period of 1 month after treatment. Women who are not of childbearing potential (i.e., who are postmenopausal or surgically sterile as well as azoospermic men) do not require contraception.

You may not qualify if…

Patients with AJCC 2017 8th edition stage IVC (metastatic) disease; or patients with fixed cervical nodal disease suggesting extranodal extension or N3 disease as suggested by lymph nodes measuring >6 cm.
Subject who has had prior radiation and/or chemotherapy for head and neck cancer.
Any history of oncologic surgical resection (transoral robotic surgery, TORS) or oncologic neck dissection prior to undergoing definitive RT or chemoradiation. Note: prior tonsillectomy as part of identification of the primary tumor site or biopsy and excisional nodal biopsy is/are acceptable provided the patient would be standardly treated to definitive treatment doses of therapy off protocol. Patients with HPV-associated unknown primary should not have undergone a neck dissection to be eligible.
Undetectable baseline HPV ctDNA result by NavDx® testing or detectable baseline HPV ctDNA result for subtypes 18, 31, 33, or 35.
Pregnant or lactating women.
Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.
Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer, and low risk prostate adenocarcinoma being managed with active surveillance. A history of another separate malignancy in remission without evidence of active disease is permitted if chance3 of recurrence is thought to be low.
