Study of Radiation (RT) Concurrent With Cetuximab in Patients With Advanced Head and Neck Squamous Cell Carcinoma (SCC)

Phase II Study of RT Concurrent w/ Cetuximab in Patients w/ Locally Advanced Head & Neck SCC Who Do Not Qualify For Standard Chemotherapy Due To Age >70 Or Co-Morbidities

This is a single-arm, phase II trial to characterize the clinical outcome of standard of care, cetuximab concurrent with radiation, in a special population (head and neck cancer patients who cannot tolerate concurrent chemoradiotherapy due to advanced age, poor performance status or concurrent illness), and to determine if biomarker response to a loading dose of cetuximab is predictive of that outcome.

Study Overview

• Status: Terminated
• Conditions: Head and Neck Cancer
• Intervention / Treatment: Drug: Cetuximab; Radiation: 50-60 Gy and 70 Gy

Detailed Description

Primary Objective 1: Determine changes in tumor EGFR, pEGFR, downstream signaling and novel phosphoproteins following a loading dose of cetuximab in patients who are poor candidates for chemoradiation (age =70 years or with significant co-morbidities) and are therefore treated with cetuximab with radiation.

Primary Objective 2: Characterize clinical outcomes, including local recurrence, progression-free survival and overall survival in these patients, and correlate these clinical outcomes with the changes in tumor EGFR, pEGFR, downstream signaling, and novel phosphoproteins.

Primary Objective 3: Describe the toxicity, in particular mucositis/dysphagia, of this regimen.

Secondary Objective 1: Conduct normal mucosa EGFR assessment for comparison with tumor sample.

Secondary Objective 2: Correlate HPV presence and titer with p53 status and clinical outcome.

Description

Inclusion Criteria:

• Patients will be limited to:

  • ≥ 70 years of age, OR
  • with co-morbidities that preclude treatment with standard platinum-based chemotherapy, as determined by the treating physician, OR
  • KPS ≤ 80, OR
  • Creatinine clearance < 30 cc/min

• Patients must give documented informed consent to participate in this study.

Exclusion Criteria:

• Prior head and neck malignancy, or history of other prior non-head and neck malignancy within the past 3 years (excluding skin cancer and early stage treated prostate cancer).
• Prior head and neck radiation or chemotherapy.
• Documented evidence of distant metastases.
• Patients with nasopharyngeal carcinoma.
• Any medical or psychiatric illness, which, in the opinion of the principal investigator, would compromise the patient's ability to tolerate this treatment.
• Patients with psychiatric/social situations that would limit compliance with study requirements are not eligible.

Intervention / Treatment

Experimental: Treatment

Drug: Cetuximab; Patients will receive a single dose of cetuximab 400 mg/m (Day 0). On day 7 (+/- 1 day), a repeat biopsy will be performed. Radiation concurrent with weekly cetuximab 250 mg/m.; Radiation: 50-60 Gy and 70 Gy; Within approximately 4 days (after single dose of Cetuximab), definitive radiation will begin (70 Gy in 35 fractions to the gross tumor, 50-60 Gy to subclinical target volumes) concurrent with weekly cetuximab 250 mg/m.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Mean Change in Tumor Epidermal Growth Factor Receptor (EGFR)	The ratio (fold change) of tumor EGFR post-loading dose/pre-loading dose of cetuximab. Reported as the mean of fold changes across all participants who had an evaluable tumor sample.	At baseline (pre-loading dose) and day 7 post-loading dose
Mean Change in Tumor Phosphorylated EGFR (pEGFR)	The ratio (fold change) of tumor pEGFR post-loading dose/pre-loading dose of cetuximab. Reported as the mean of fold changes across all participants who had an evaluable tumor sample.	At baseline (pre-loading dose) and day 7 post-loading dose
Progression Free Survival Rate	Percentage of participants who survived without recurrent disease, from the time of enrollment to 1 and 2 years.	At 1 and 2 years
Overall Survival Rate	Percentage of participants alive at 1 and 2 years after enrollment.	At 1 and 2 Years
Number of Participants With Treatment Related Toxicities	Toxicities are measured by number of participants who experience one or more types or indicator of toxicity, shown as all grades and grades 3-4. As each participant could have multiple toxicities, the total number of incidents outnumbers the number of participants. Toxicities are graded according to the CTCAE v4.	3 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in Tumor EGFR Level Relative to EGFR in Normal Mucosa	Normal mucosa EGFR was assessed for comparison with EGFR in tumor sample. The fold change in tumor EGFR level at post-loading dose/pre-loading dose of cetuximab, relative to fold change in normal mucosa EGFR level post-loading dose/pre-loading dose of cetuximab was summarized across all participants who had an evaluable tumor sample and normal mucosa sample. The value reported is the ratio of fold change in tumor/fold change in buccal EGFR.	At baseline (pre-loading dose) and day 7 post-loading dose
Change in Tumor pEGFR Level Relative to pEGFR in Normal Mucosa	Normal mucosa pEGFR was assessed for comparison with pEGFR in tumor sample. The fold change in tumor pEGFR level post-loading dose/pre loading dose of cetuximab, relative to fold change in normal mucosa pEGFR level post-loading dose/pre-loading dose of cetuximab was summarized across all participants who had an evaluable tumor sample and normal mucosa sample. The value reported is the ratio of fold change in tumor/fold change in buccal pEGFR.	At baseline (pre-loading dose) and day 7 post-loading dose
