Official Title: Phase II Randomized Trial of the Combination of Cetuximab and Sorafenib or Single Agent Cetuximab in Patients With Refractory, Recurrent and/or Metastatic Squamous Cell Carcinoma of the Head and Neck

Brief Summary: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Sorafenib tosylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. It is not yet known whether cetuximab is more effective when given alone or together with sorafenib tosylate in treating patients with head and neck cancer. This randomized phase II trial is studying cetuximab to see how well it works when given together with or without sorafenib tosylate in treating patients with refractory, recurrent, and/or metastatic head and neck cancer.

Detailed Summary:

PRIMARY OBJECTIVES:

I. Compare the progression free survival (PFS) of the combination of cetuximab and sorafenib to that of cetuximab alone in patients with recurrent, refractory or metastatic squamous cell carcinoma of the head and neck (SCCHN).

SECONDARY OBJECTIVES:

I. To evaluate the response rate, overall survival (OS) and toxicity of the combination of cetuximab and sorafenib and of cetuximab alone.

II. To evaluate the presence of EGFRvIII mutation, increased EGFR gene copy number and activated EGFR gene expression signature, and correlate with clinical parameters (RR, OS and PFS) in the cetuximab alone and cetuximab/sorafenib arms.

III. To evaluate whether VEGF receptor family and their ligand expression can predict response to cetuximab/sorafenib.

IV. To determine the proteomic profiles in serum and tumors that can predict the response and survival upon the treatment with cetuximab or cetuximab/sorafenib.

V. To evaluate the effect of therapy on both general and head and neck specific functionality, symptom burden and QOL.

OUTLINE: This is a multicenter study. Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive cetuximab IV over 60-120 minutes on days 1, 8, and 15 and oral placebo twice daily on days 1-21. (oral placebo closed as of 02/18/2010).

ARM II: Patients receive cetuximab IV over 60-120 minutes on days 1, 8, and 15 and oral sorafenib tosylate twice daily on days 1-21.

Estimated probable duration of life without disease progression, from on‐study date to earlier of progression date or date of death from any cause, using the Kaplan‐Meier method with censoring (see analysis population description for additional details). Disease progression is defined under Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 as >=20% increase in sum of longest diameters of target lesions, unequivocal progression of non‐target lesions, or appearance of new lesions.



Original Primary Outcome: Progression-free survival

Current Secondary Outcome:

  • Best Response [ Time Frame: On-treatment date to date of disease progression (assessed up to 3 years) ]

    Number of patients in each response category, per Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, summarized as follows for target lesion criteria (see RECIST v1.1 for additional details): complete response (CR),disappearance of target lesions; partial response (PR), >=30% decrease in sum of longest diameter of target lesions; progressive disease (PD), >=20% increase in sum of longest diameter (LD) of target lesions or appearance of new lesions; stable disease (SD), insufficient change in target lesions or new lesions to qualify as either PD or SD.

    Patients are categorized according to the best response achieved prior to occurrence of progressive disease, where best response hierarchy is CR>PR>SD>PD.

  • Overall Survival (OS) [ Time Frame: On-study date to date of death from any cause (assessed up to 3 years) ]
    Estimated probable duration of life from on‐study date to date of death from any cause, using the Kaplan‐Meier method with censoring (see analysis population description for additional details)
  • Number of Participants With Each Worst‐Grade Toxicity [ Time Frame: On-study date to 30 days following final dose of study drug ]
    Count of patients according to the worst‐grade toxicity experienced by each, where worst‐grade toxicity is per NCI common toxicity criteria: grade 1, mild; grade 2, moderate; grade 3, severe; grade 4, life‐threatening; grade 5, death
  • Gene Expression Levels [ Time Frame: Pre-therapy and every 21 days for up to 9 weeks ]
    Gene Expression Levels were to be addressed using mostly descriptive statistics.
  • Overall Survival Associated With Immunomodulatory Cytokines [ Time Frame: Pre-therapy ]
    Twelve immunomodulatory cytokines were selected based on previous a feasibility study. One cytokines, HGF, was eliminated due to extremely low expression. Three cytokines, TGF-beta 1, IL-8 and VEGF were evaluated for association with survival.


Original Secondary Outcome: Overall survival
