Plain English Summary
Background and study aims
Electrochemotherapy is a cancer treatment. It works though injection of a chemotherapeutic drug (such as bleomycin) and then applying an electric pulse to send the chemotherapy into the cancer cells. Between 70-80% of tumours respond to this treatment. It is currently used for treating skin cancer in 150 centres throughout Europe. The aim of this study is to test how effective and safe electrochemotherapy is in patients with head and neck cancers and measure the concentration of drug bleomycin in the serum (blood) and in the tumour itself.
Who can participate?
Adults (aged over 18) with head or neck cancer, that have not had chemotherapy for at least 2 weeks and are expected to live for more than 3 months.
What does the study involve?
All participants have the electrochemotherapy treatment. The procedure is standardized and is performed according to the published Standard Operating Procedure (SOP) for electrochemotherapy. The chemotherapy drug Bleomycin is injected intravenously (though a needle in a vein) in dose of 15,000 IU/m2. After 8 minutes, electric pulses are delivered to the tumour in order to send the bleomycon into the cancer cells. The response of the tumour to the treatment is assessed at one month and again at two months.
What are the possible benefits and risks of participating?
So far minimal or no side effects have been reported. Due to the pain caused by the electric pulses, local or general anaesthesia will be needed. There may be some reddening of the skin but no pain after the treatment is complete is expected.
Where is the study run from?
The University Medical Centre Ljubljana and Institute of Oncology Ljubljana (Slovenia)
When is the study starting and how long is it expected to run for?
July 2015 to December 2017
Who is funding the study?
Slovenian Research Agency

Condition
Cancer in the head and neck region
Intervention
All patients are treated with electrochemotherapy with bleomycin, according to European Standard Operating Procedures of Electrochemotherapy. Bleomycin will be injected intravenously in a dose of 15,000 IU/m2 skin surface. The electric pulses will be delivered by electrodes to the tumors generated by electric pulse generator Cliniporator (IGEA, Carpi, Italy) 8-28 minutes after bleomycin injection. During the procedure tumor tissue and blood samples will be collected for the purpose of pharmacological analysis. Patients will be followed up at 1, 2, 4, 8, 12, 18 and 24 months after the treatment.

Primary outcome measure
1. Antitumor efficiency of electrochemotherapy, evaluated by measurement of tumor response in accordance with RECIST criteria, 1 and 2 months after the treatment
2. Safety of electrochemotherapy. Any adverse events will be recorded according to National Cancer Institute (NCI) criteria
Secondary outcome measures
Setting a time frame of optimal concentration of bleomycin in tumors and plasma for effective electrochemotherapy treatment.
