Clinical Trial Summary

This pilot clinical trial studies how well metformin hydrochloride works in affecting cytokines and exosomes in patients with head and neck cancer. Metformin hydrochloride may reduce the metabolic activity of cancer cells and of surrounding supportive tissues.

Description:

PRIMARY OBJECTIVES: I. To assess the capacity of metformin hydrochloride (metformin) to alter the cytokine and exosome profiles. II. To assess the capacity of metformin to mitigate known side effects of external beam radiation therapy including inflammation, mucositis, dysphagia, xerostomia, and fatigue. SECONDARY OBJECTIVES: I. Assess safety and tolerability of metformin treatment in subjects undergoing external beam radiation treatment for head and neck cancer. II. To determine the effect of metformin treatment on symptoms of xerostomia as assessed by the Xerostomia Questionnaire (XQ). III. To determine the effect of metformin treatment on symptoms of mucositis as assessed by World Health Organization (WHO) classification. IV. To determine the effect of metformin treatment on symptoms of dysphagia as assessed by the MD Anderson Dysphagia Inventory. V. To determine the effect of metformin treatment on symptoms of fatigue as assess by the Multidimensional Fatigue Inventory (MFI).

Recruitment information / eligibility

• Enrollment: 9
• Est. completion date: July 31, 2020
• Est. primary completion date: July 31, 2020
• Accepts healthy volunteers: No
• Gender: All
• Age group: 18 Years to 90 Years

Eligibility

Inclusion Criteria:

• Subjects with a diagnosis of head and neck cancer biopsy proven, and who are candidates for radiation therapy
• All subjects must be able to comprehend and sign a written informed consent document.

Exclusion Criteria:

• Subjects who are pregnant or may become pregnant during metformin administration; pregnancy testing will be done in conjunction with preradiation protocols
• Subjects on metformin for any reason during the preceding 4 weeks
• Diabetic subjects are eligible if they are not taking metformin or insulin
• Subjects who have received iodinated contrast dye must wait 12 hours prior to starting Metformin. If a CT scan with contrast is scheduled after screening and consent, the metformin cannot be taken until after the CT with contrast has been completed and they have waited 12 hours.
• Patients with plasma creatinine level greater than 1.3 mg/dL
• Patients with plasma bicarbonate less than 22 mEq/L or history of lactic or any other metabolic acidosis
• Patients with history of congestive heart failure
• Patients with myocardial ischemia or peripheral muscle ischemia
• Patients with sepsis or severe infection
• Patients with history of lung disease currently requiring any supplemental oxygen treatment
• Patients scheduled for radiation less than 6 days from enrollment
• Patients with history of hepatic dysfunction or hepatic disease and abnormal liver function tests; patients who have a history of hepatic dysfunction or hepatic disease and normal liver function tests will be eligible to participate
• Patients with a current history (in the past 30 days) of heaving drinking which is defined in accordance with CDC definition as more than 8 drinks per week for women and more than 15 drinks per week for men. A standard drink contains .6 ounces of pure alcohol. Generally, this amount of pure alcohol is found in 12-ounces of beer, 8-ounces of malt liquor, 5-ounces of wine, 1.5-ounces or a "shot" of 80-proof distilled spirits or liquor (e.g., gin, rum, vodka, or whiskey). While on study, patients should limit their alcohol consumption to no more than 8 drinks per week for women and no more than 15 drinks per week for men. Patients who feel they cannot comply with this recommendation are not eligible".
• All medications are permitted except those that are contraindicated with metformin under current Food and Drug Administration (FDA) recommendations

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cytokine/Chemokine Profile	Mixed effects linear regression will be used to model longitudinal measurements of each cytokine.	Up to 1 year
Secondary	Mucositis Assessed Using WHO Classification	Analysis will be primarily descriptive. The distribution of swallowing function and mucositis scores will be summarized by arm using means, medians, standard deviations, and ranges.	Up to 1 year
Secondary	Objective Response Rate	The objective response rate will be estimated by arm along with an exact 95% binomial confidence interval	Up to 2 years
Secondary	Exosome Profile	Longitudinal measurements of exosomes will also be modeled using mixed effects linear regression. This analysis is treated as separate from the cytokine questions and the p-value will not be adjusted.	Up to 1 year
Secondary	Incidence of Toxicities	Evaluated according to National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0	Up to 2 years
