Brief summary

This pilot clinical trial studies how well durvalumab before surgery works in treating patients with oral cavity or oropharynx cancer. Monoclonal antibodies, such as durvalumab, may interfere with the ability of tumor cells to grow and spread.

Detailed description

PRIMARY OBJECTIVES: I. To investigate the effect of durvalumab on local and systemic immune activation by HPV status in patients with oral cavity and oropharynx head and neck squamous cell carcinoma (HNSCC). II. To examine the effects of durvalumab on systemic immune response to HPV and tumor associated antigens. III. To examine the effects of durvalumab on immune regulatory mechanisms. IV. To explore the association between levels of immune-regulatory micro-ribonucleic acid (miR) in plasma and saliva and immune response. SECONDARY OBJECTIVES: I. Investigate the effect of the treatment with durvalumab on the computed tomography (CT) scan and positron emission tomography (PET) scan response. II. Evaluate the safety of a short induction treatment with durvalumab. OUTLINE: Patients receive durvalumab intravenously (IV) over approximately 60 minutes on day 1. Treatment repeats every 2 weeks for up to 2 courses in the absence of disease progression or unacceptable toxicity. Within 3-17 days after last dose administration of durvalumab, patients undergo surgery. Patients may receive an additional dose of durvalumab if time to surgery is longer than 30 days. After completion of study treatment, patients are followed up for 90 days.

Toxicity grades Grade I (mild), Grade II (moderate), Grade III (severe), Grade IV (life threatening) and Grade V (fatal). Toxicities of greater than or equal to Grade III (except infusion reaction) are considered worse outcomes.

Population: This pre-specified outcome is dependent upon 1) patients having a measurable response and 2) availability of comparable cohorts of HPV positive and negative samples. Since there was a lack of measurable clinical response in all patients and the enrolled cohorts were unbalanced, the data for this outcome was not measured/evaluated and therefore is not available for analysis.

Secondary

Standardized Uptake Value (SUV) as Measured by PET Scans

Change in SUV activity as measured by PET scans from baseline to post-treatment not specific to HPV status.

Time frame: Up to 18 months

Population: This pre-specified outcome is dependent upon 1) patients having a measurable response and 2) availability of comparable cohorts of HPV positive and negative samples. Since there was a lack of measurable clinical response in all patients and the enrolled cohorts were unbalanced, the data for this outcome was not measured/evaluated for all patients.
