Medpulser Electroporation With Bleomycin Study to Treat Anterior Head and Neck Squamous Cell Carcinoma

Study Overview
=================
Brief Summary
-----------------
The purpose of the study is to evaluate Medpulser electroporation (EPT) with bleomycin with regard to local tumor recurrence, disease-free survival, and overall survival rates versus surgery in recurrent or secondary primary squamous cell carcinoma (SCC) of the anterior oral cavity, soft palate, or tonsil.

Detailed Description
-----------------
Recurrent tumors in head and neck squamous cell carcinoma usually have a poor prognosis. In patients suitable for salvage surgery of their recurrent disease, the success rate for local control has been reported to be 40-50%. The surgical treatment of H&N SCC frequently results in significant loss of organ function (e.g., inability to swallow, speak, etc.) and/or permanent disfigurement. There is a compelling and unmet medical need for a local therapy that destroys tumors while preserving function status and appearance in patients with primary, recurrent, or metastatic H&N SCC. Comparison: To compare function status at 4 months after treatment with bleomycin-EPT or surgery in patients with locally recurrent or second primary SCC of the anterior oral cavity, soft palate, or tonsil that have failed primary curative therapy and in whom surgical resection is seen as an option for disease control.

Official Title

Participation Criteria

Eligibility Criteria
-----------------
Inclusion Criteria: The presence of SCC of the anterior oral cavity, soft palate or tonsil must be confirmed by histological examination of a tissue sample (e.g., biopsy) obtained within 1 month of the patient receiving the study treatment. Recurrent or second primary disease in patients where surgical resection is seen as an option for disease control. The length of the longest diameter of the study lesion must be < 5 cm and the calculated treatment volume must be < 60.0 cm3 (tumor volume plus a 0.5 cm margin around the tumor) for the study lesion [where treatment volume = 0.5 (A+1) (B+1)2 and where A = length of the longest diameter (cm), B = the next longest diameter perpendicular to A (cm)]. Tumor burden must be completely encompassed by surgery or bleomycin-EPT. Age: 18 years or older. Men and women of childbearing potential must use physician approved contraceptive methods for 7 days following bleomycin-EPT. Hematopoietic status: Absolute neutrophil count (ANC) > 1000/uL Platelets > 75,000/mm3 Prothrombin time:international normalized ratio (PT:INR) ? 1.5 (correctable with vitamin K injection) Blood chemistry status: Transaminases < 3 times upper limit of normal Total bilirubin < 2.5 mg/dL Creatinine < 2.5 mg/dL A written Informed Consent form must be signed prior to the patient receiving any study procedures or treatments. Exclusion Criteria: Patients with tumors suspected of involving a 50% or greater encasement of a blood vessel as measured by magnetic resonance imaging (MRI) or computed tomography (CT) scan. Patients with tumors having bone invasion. Patients with any metallic implants in the treatment field. Patients with hypersensitivity to bleomycin. Patients who have received or will exceed a total lifetime dose of bleomycin greater than 400 units. Patients deemed unsuitable for general anesthesia. Patients with a significant history of emphysema or pulmonary fibrosis. Patients with indwelling cardiac pacemakers who cannot tolerate a period with pacemaker turned off. Patients with a history of uncontrolled cardiac arrhythmia. Women who are pregnant, or are nursing. Women of childbearing potential must have a negative beta-human chorionic gonadotropin (beta-HCG) test within 7 days of study treatment. Radiation therapy to the treatment area within 8 weeks of study treatment. Chemotherapy or other cancer therapy (e.g., surgery, cryotherapy, etc.) to the treatment area within 4 weeks of study treatment. Patients participating in a clinical study for an investigational drug or device within 4 weeks prior to the study treatment. Patients previously randomized to this study.
