Overview
Brief Summary
Carboplatin, nab-paclitaxel, and nivolumab combination will be administered for three cycles of three weeks duration each. TORS or RT/CRT will be performed after induction chemotherapy (i.e. day 64 of therapy). Patients with low risk and small volume tonsillar disease (T1-T2, non-bulky N2A-N2B with ≤2 non-lower neck lymph nodes measuring ≤5 cm in size) or base of tongue disease (T1-2 with lateralized primary ≤3 cm, non-bulky N2A-N2B with ≤2 non-lower neck lymph nodes measuring ≤5 cm in size) who have ≥50% reduction by RECIST following induction chemotherapy will undergo TORS and selective nodal dissection. De-intensified adjuvant RT will be given for adverse pathologic features. Patients may refuse TORS treatment.
Patients with low risk, who do not qualify for TORS (due to volume of disease or poor visualization/access) or refuse TORS, who have ≥50% reduction by RECIST following induction chemotherapy will be given de-intensified treatment with radiation alone to 50 Gy.
Before induction chemotherapy, patients will undergo examination under anesthesia and direct laryngoscopy to tattoo and photograph the primary tumor to plan the post-induction resection. Adjuvant nivolumab will be offered to all patients for 6-months post completion of definitive therapy (7 doses given as a flat dose of 480mg, every four weeks).
Detailed Description
A phase II trial in human papillomavirus (HPV)-positive oropharyngeal squamous cell cancer (as determined by p16 immunohistochemistry with confirmatory ISH or PCR) to determine radiologic response to induction chemotherapy with nivolumab. Patients will undergo evaluation by a multidisciplinary team prior to risk assessment. The patients will be assigned to high or low risk groups based on tumor size, lymph node involvement, and smoking history. Patients will be assigned to treatment with induction chemotherapy with carboplatin, nab-paclitaxel, and nivolumab. Radiologic response to induction chemotherapy according to RECIST measurement of tumor shrinkage will then be used for therapeutic stratification of locoregional therapy, consisting of either transoral robotic surgery (TORS) or radiation with or without chemotherapy. Patients with low risk disease (see table above) and small volume tonsillar/BOT disease (T1-2 primary, non-bulky N2A-N2B nodal status) who have ≥50% reduction by RECIST following induction chemotherapy will undergo TORS for primary site resection and selective nodal dissection as a definitive treatment if technically feasible with adjuvant radiation for adverse pathologic features. Patients with other low risk tumors e.g. with higher volume disease, or who refuse surgery, who also have ≥50% reduction by RECIST following induction chemotherapy will be given de-intensified treatment with radiation alone to 50 Gy (no chemotherapy). Patients with low risk features and \<50% but ≥30% reduction OR high risk features (T4, bulky N2B or N2C-N3, \>10 pack-years tobacco use) with ≥50% reduction will receive de-intensified chemoradiation with concurrent cisplatin-RT to 50 Gy (5 weeks) or TFHX to 45 Gy (3 cycles/6 weeks). Patients with low risk features and \<30% reduction OR high risk disease with \<50% reduction or any patients with progressive disease during induction chemotherapy will undergo chemoradiotherapy with concurrent cisplatin-RT to 70 Gy (7 weeks) or TFHX to 75 Gy (5 cycles/10 weeks). Patients with both high and low risk features who have ≥50% reduction will receive locoregional therapy targeting the pre-chemotherapy extent of disease only. Adjuvant nivolumab will be offered to all patients for 6-months post completion of definitive therapy (7 doses given as a flat dose of 480mg, every four weeks).

Eligibility Criteria
Inclusion Criteria
- •Patients must have pathologically confirmed HPV-positive head and neck squamous cell carcinoma of the oropharynx. Confirmed HPV-positive disease of other subsites are uncommon but also eligible.
- •HPV testing must be compliant with the following criteria:
- •p16 IHC positivity is sufficient to enroll and initiate treatment (p16 IHC interpretation to follow guidelines by Jordan and Lingen et al89).
- •p16 IHC positivity is to be validated using an HPV PCR during the induction phase. This is essential as HPV genotype influences treatment arm allocation, with non-HPV16 HPV strains being considered high risk.
- •Availability of ≥10 unstained 5 micron slides (to be provided to HTRC at the University of Chicago). Patients who cannot fulfill this requirement will need to undergo a new biopsy prior to enrollment on study.
- •Patients must be at least 18 years of age.
- •Patients with AJCC (7th edition, 2010) N2-N3 nodal disease or T3-T4 primary tumor.
- •Measurable disease (either primary site and/or nodal disease) by RECIST 1.1 criteria.
- •No previous radiation or chemotherapy for a head and neck cancer.
- •No complete surgical resection for a head and neck cancer within 8 weeks of enrollment (although lymph node biopsy including excision of an individual node with presence of residual nodal disease, or surgical biopsy/excision of the tumor with residual disease is acceptable).
Exclusion Criteria
- •Unequivocal demonstration of distant metastases (M1 disease).
- •Unidentifiable primary site.
- •Intercurrent medical illnesses which would impair patient tolerance to therapy or limit survival. Including but not limited to ongoing or active infection, immunodeficiency, symptomatic congestive heart failure, pulmonary dysfunction, cardiomyopathy, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance.
- •Pregnant and nursing women are excluded because of the potential teratogenic effects and potential unknown effects on nursing newborns (please see above paragraph under inclusion criteria regarding WOCBP) 31 Version Date: 12/28/2016
- •Prior surgical therapy other than incisional/excisional biopsy or organ-sparing procedures such as debulking of airway-compromising tumors. Residual measurable tumor is required for enrollment on study as outlined above
- •Patients receiving other investigational agents.
