Phase II Trial Evaluating Axitinib In Patients With Unresectable, Recurrent Or Metastatic Head And Neck Cancer

Phase 2

Completed

Conditions: Head and Neck Squamous Cell Carcinoma

Interventions: Drug: Axitinib (AG-013736)

Registration Number: NCT01469546

Lead Sponsor: University of Michigan Rogel Cancer Center

Brief Summary: The purpose of this study is to investigate a new agent Axitinib in the treatment of head and neck cancer.

This is a new drug that is given as a pill twice a day to treat cancer. This is one of the new, "smart" drugs. It binds to a protein on the surface of the cancer cell called VEGFR, and this way it slows down the growth of cancer cells and kills them. Head and neck cancer cells are known to carry this protein on their surface. Research in animals and in patients with other kinds of cancer showed that Axitinib can be effective at killing cancer cells, or stopping their growth, by this mechanism. It is generally a safe drug that is given by mouth. The investigators do not know, however, whether Axitinib is effective in head and neck cancer. This research study is being conducted to learn if Axitinib works in head and neck cancer, and also to learn to predict who would benefit from it. Four blood draws will be done to check special blood tests while the subjects are treated with Axitinib. These will be drawn at the same time as your routine labs, and there will not be additional sticks needed. A biopsy of the tumor before and after 1 month of treatment may be obtained to test how the cancer cells are responding to treatment. By testing these blood and tissue samples, the researchers will look at special tests (protein molecules) to try to determine what kind of head and neck patients would best respond to this drug. This is an open-label study, meaning that all subjects are on the active drug and there is no placebo (sugar pill).

The baseline systolic blood pressure readings must be ≤140 mm Hg, and the baseline diastolic blood pressure readings must be ≤90 mm Hg. Patients whose hypertension is controlled by antihypertensive therapies are eligible.
Women of childbearing potential must have a negative serum or urine pregnancy test within 3 days prior to treatment.
Signed and dated informed consent document indicating that the patient (or legally acceptable representative) has been informed of all pertinent aspects of the trial prior to enrollment.
Willingness and ability to comply with scheduled visits, treatment plans, including willingness to take Axitinib, laboratory tests, and other study procedures.

Exclusion Criteria

History of hemoptysis.
Gastrointestinal abnormalities causing impaired absorption requiring intravenous alimentation, prior surgical procedures affecting absorption including gastric resection, treatment for active peptic ulcer disease in the past 6 months, active gastrointestinal bleeding, unrelated to cancer, as evidenced by hematemesis, hematochezia or melena in the past 3 months without evidence of resolution documented by endoscopy or colonoscopy, malabsorption syndromes.
Previous treatment with anti-angiogenesis agents including thalidomide, or inhibitors of epidermal growth factor (EGF), platelet derived growth factor (PDGF), or fibroblast growth factors (FGF) receptors within 30 days preceding study entrance.

Axitinib (AG-013736)	Axitinib (AG-013736)	A prospective, single-institution, single-arm phase II study of Axitinib in patients with unresectable recurrent and metastatic head and neck squamous cell carcinoma who have received no more than two prior lines of systemic therapy for recurrent or metastatic head and neck cancer.

Primary Outcome Measures

Name	Time	Method
Percentage of Patients Alive and Free of Progression at 6 Months	6 months	To determine the 6-months progression-free survival (PFS) rate in patients with unresectable recurrent and metastatic head and neck cancer treated with Axitinib.

Secondary Outcome Measures

Name	Time	Method
Median Progression-Free Survival (PFS)Time	6 months	To evaluate PFS time in patients with Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck (R/M SCCHN) treated with Axitinib.
Number of Participants Who Achieved Complete Response, Partial Response or Stable Disease	2 years	To determine the disease control rate (complete response+partial response+stable disease), in patients with unresectable recurrent and metastatic head and neck cancer treated with Axitinib. Response Evaluation Criteria in Solid Tumors (RECIST version 1.0) will be used. Complete Response is defined as the disappearance of all tumor for a period of one month. Partial Response is defined as a 30% or more decrease in the sum of the longest diameters (LD) of all measured lesions without any evidence of progression of any lesion or the appearance of any new lesion for a period of one month. Stable Disease is defined as any change in measurable disease which is less than the criteria for partial remission or progression without any evidence of new lesions and persisting for at least 2 evaluations or 2 months.
Number of Patients That Experienced Grade 3 or 4 Toxicities	28 Days Post Treatment	The number of patients who develop these while on treatment and for 28 days after cessation of axitinib, and graded in severity per CTCAE v. 3.0 and as described in the protocol. According to the CTCAE v. 3.0, grade 3 toxicities are severe and grade 4 toxicities are life-threatening or disabling.
