Details and patient eligibility

About

This is a Phase II trial of definitive chemoradiotherapy (CTRT) given with the protease inhibitor,Nelfinavir (NFV), in patients with locally advanced head and neck. Eligible patients will receive a "lead-in" period of Nelfinavir (1250 mg po bid) for 7-14 days prior to initiation of CTRT. Nelfinavir will then be given concurrently with platinum-based chemotherapy and radiation therapy (planned total dose of 70 Gy over 7 weeks).

Full description

This is a single-arm Phase II study of organ-preservation chemoradiotherapy given in combination with the protease inhibitor, Nelfinavir, in patients with stage II, IVa, or IVb (per AJCC version 7) squamous cell carcinoma of the oral cavity, oropharynx, larynx, or hypopharynx. Patients start treatment with Nelfinvir at a dose of 1250 mg twice daily for 7-14 days, before continuing Nelfinvir at this dose concurrent with chemotherapy and radiation therapy (for a total dose of 70 Gy over a period of 7 weeks).

Inclusion and exclusion criteria

Inclusion Criteria:

Patients ≥ 18 years old.
Histologically confirmed diagnosis of squamous cell carcinoma of the oral cavity, oropharynx, larynx, or hypopharynx stages III, IVa, or IVb, p16-negative on immunohistochemistry
Determined by the treating physician to be a candidate for organ preserving, concurrent standard chemotherapy and radiation therapy to the head and neck with definitive intent.
ECOG Performance Status 0-2
Patients must sign an informed consent document that indicates they are aware of the investigational nature of the treatment in this protocol as well as the potential risks and benefits.
The effects of EF5 on the developing human fetus are unknown. For this reason, women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control) prior to study entry, during study, until 1 month after completion of the final FMISO PET/CT scan. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Serum pregnancy testing will be required for women of childbearing potential.
Ability to understand and the willingness to sign a written informed consent.

Exclusion Criteria

Prior radiation therapy to the head and neck
Prior chemotherapy within the past 5 years
Previous therapy with a human immunodeficiency virus (HIV) protease inhibitor
Pregnant or lactating patients.
Patients with known HIV disease. These patients have a high probability of treatment with anti-retroviral therapy which may interact with the nelfinavir.
Absolute Neutrophil Count ≤ 1500 per mm3
Platelet count ≤ 100,000 per mm3
Serum creatinine > 1.5 times the upper limit of normal
Serum AST or ALT > 2 times the upper limit of normal
Serum bilirubin > 1.2 mg/dl
Weight loss of > 10% over the past 6 months which is due to tumor wasting syndrome

History of allergic reactionsattributed to Flagyl (metronidazole), which has a chemical structure similar to FMISO.
Uncontrolled intercurrent illness including, but not limited to symptomatic congestive heart failure, unstable angina pectoris, or psychiatric illness/social situations that would limit compliance with study requirements.
