- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: None
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Histologically or cytologically documented squamous cell carcinoma of the oropharynx, larynx or hypopharynx. HPV status will not be assessed for eligibility; while HPV status may affect response to therapy, efficacy is not an outcome measure for this phase I study.~* Candidate for primary chemoradiation as decided by an interdisciplinary team including otolaryngology, medical oncology, and radiation oncology.~* Cancer should be staged via AJCC as stage II, III or IVa.~* Age ≥ 18 years~* ECOG performance status 0-2 (Karnofsky \> 50%, see Appendix A).~* Patients must have normal organ and marrow function as defined below:~* leukocytes ≥ 3,000/mm3~* absolute neutrophil count ≥ 1,500/mm3~* platelets ≥ 100,000/mm3~* total bilirubin \< 1.5 mg/dl~* Hgb A1C \< 8%~* AST(SGOT) \< 2 X institutional upper limit of normal~* creatinine \< 1.5 X institutional upper limit of normal OR calculated creatinine clearance ≥ 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal.~* Not pregnant. Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.~* Ability to understand and the willingness to sign a written informed consent document.~Exclusion Criteria:~* Life expectancy of 3 or less months.~* Prior neck and/or upper thoracic radiotherapy that would cause an overlap of treatment fields.~* Prior therapy to the head and neck, with the intent to treat, the current diagnosis of head \& neck cancer.~* Known / established G6PD (glucose-6-phosphate dehydrogenase) deficiency.~* Chronic system corticosteroids for any reason (inhaled corticosteroids are allowed). Pre-medication for chemotherapy is acceptable.~* Other investigational agents/therapy with the intention to treat the disease under study (observational or imaging trials are acceptable).~* Uncontrolled diabetes defined as a hemoglobin A1C level \> 8% (therapeutic action is indicated at greater than 8%).~* Diabetes is not exclusionary provided the patient is not maintained with either oral medications or insulin.~* Uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements as determined by study team members.~* Pregnant or lactating women: The risks of radiation and chemotherapy to a fetus are well documented.
