Induction chemotherapy is gaining momentum in the management of locally advanced squamous cell carcinoma of the head and neck (SCCHN). The combination of docetaxel, cisplatin, and 5-FU (TPF) was superior compared with PF in a Phase III clinical trials73,74. We have completed a Phase II clinical trial that showed that docetaxel, cisplatin, and cetuximab (TPE) is highly active and well tolerated as induction chemotherapy in SCCHN (Argiris et al. ASCO 2008; A6002). Preliminary survival results are very encouraging. 39 patients were enrolled and with median follow up 26 months the 2-year PFS was 70% and the 2-year OS 84%.The combination of chemotherapy plus cetuximab is already a standard treatment in recurrent or metastatic SCCHN47. Therefore, TPE can be used as the platform for the addition of novel agents.

EGFR and VEGF are among the most important and validated molecular targets in cancer therapy. The incorporation of novel targeted therapies to chemotherapy and radiotherapy is of particular interest in head and neck cancer, and may improve efficacy without significantly increasing toxicity. A Phase III trial of carboplatin/paclitaxel/bevacizumab with or without cetuximab in advanced NSCLC has been proposed by SWOG. Bevacizumab is currently being investigated in SCCHN with promising results. A Phase II study investigating the combination of pemetrexed and bevacizumab (UPCI 05-002) as well as a Phase II trial of cetuximab and bevacizumab (UPCI 05-087) in recurrent or metastatic SCCHN are ongoing at the University of Pittsburgh with encouraging results (ASCO 2008 and ASCO 2009). In this study, 32 have been already enrolled. There was only 1 patient with grade 3 hemorrhage. The objective response rate is 20%, the median PFS 2.8 months and the median OS 8.1 months.

In order to further improve the efficacy of TPE and the rate of complete responses we propose to add bevacizumab to the TPE followed by XPE regimen we developed at the University of Pittsburgh. Due to non-overlapping toxicities and based on our prior experience we anticipate that the regimen will be well tolerated. Moreover, we plan to obtain tumor biopsies and blood samples in the first cycle and evaluate the modulation of biomarkers post combination therapy. Data from induction with TPE (presented at ASCO 2009) indicate the potential significance of cytokine levels in patient outcome. Also, we will evaluate the feasibility of subsequent concurrent radiation, cisplatin, cetuximab and bevacizumab. Patients with stable disease in the primary could be considered candidates to surgical resection at the discretion of their physician, if the tumor is resectable.

Inclusion Criteria:

• Patients with AJCC 6th edition stage III-IVB head and neck cancer, all sites, including unknown primary tumors.
• Prior to entry in the study the resectability and alternative treatment options for each patient will be determined by a team composed of an Ear, Nose, and Throat Surgeon, a Radiation Oncologist and a Medical Oncologist. Stage determination, optimal local treatment, and its timing according to this protocol will be determined at this evaluation. The unequivocal demonstration of distant metastasis (M1) confers ineligibility.
• Histologically or cytologically confirmed diagnosis of squamous cell or poorly differentiated carcinomas, or WHO types I-III of the nasopharynx.
• Unidimensionally measurable disease is required (RECIST 1.1).
• No prior chemotherapy, biologic/molecular targeted therapy (including any prior therapy which specifically and directly targets the EGFR pathway), or radiotherapy for head and neck cancer.
• Prior surgical therapy will consist only of incisional or excisional biopsy, and organ sparing procedures such as debulking of airway compromising tumors or neck dissection in a patient with an existing primary tumor. Any non-biopsy procedure must have taken place > 4 weeks but < 3 months of initiating protocol treatment.
• ECOG performance status 0-1.
• Age of at least 18 years.
• Informed consent must be obtained from all patients prior to beginning therapy. Patients should have the ability to understand and the willingness to sign a written informed consent document.
• All patients should have their tumor tissue tested for HPV and will consent to have available archival tumor samples, unstained slides or blocks from previous diagnostic or therapeutic procedures submitted for correlative studies, including assessment of target molecules EGFR, VEGF and related biomarkers. Also, patients must agree to submit blood samples for correlative studies at least at baseline.
• Absolute neutrophil count equal to or greater than 1500/µl, Platelet count equal to or greater than 100,000/µl
• Creatinine clearance 60 ml/min or higher calculated using the Cockcroft-Gault formula:

Calculated Creatinine Clearance = (140-age) X actual body wt.(kg) 72 X serum creatinine Multiply this number by 0.85 if the patient is female

• Total bilirubin within normal limits and AST/ALT less than 3 times the upper limit of normal.
• Urine to protein to creatinine (UPC) ratio should be <1.0 at screening

NOTE: UPC ratio of spot urine is an estimation of the 24 urine protein excretion - a UPC ratio of 1 is roughly equivalent to a 24-hour urine protein of 1gm. UPC ratio is calculated using one of the following formula:

• [urine protein]/[urine creatinine] - if both protein and creatinine are reported in mg/DI

• [(urine protein) × 0.088]/[urine creatinine] - if urine creatinine is reported in mmol/L

  • Patients with a prior history of squamous cell or basal carcinoma of the skin or in situ cervical cancer must have been curatively treated. Patients with a history of other prior malignancy must have been treated with curative intent and must have remained disease-free for 3 years post diagnosis.
  • Patients may not be receiving any other investigational agents.

Exclusion Criteria:

• History of severe allergic reactions attributed to docetaxel or compounds of similar chemical or biologic composition to docetaxel, or other drugs formulated with polysorbate 80.
• Prior severe infusion reaction to a monoclonal antibody or known hypersensitivity to any component of bevacizumab
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection or psychiatric illness/social situations that would limit compliance with study requirements.
• All patients will have a baseline EKG. If abnormalities consistent with active coronary artery disease are detected, the patient will be referred to a cardiologist for appropriate evaluation and management prior to treatment on study
• No patients with significant baseline sensory or motor neurologic deficits (> grade I neuropathy) will be treated on this study.
• Because patients with immune deficiency are at increased risk of lethal Infections when treated with marrow-suppressive therapy, HIV-positive patients are excluded from the study. Appropriate studies will be undertaken in patients with HIV and those receiving combination anti- retroviral therapies when indicated.
