简要总结
Electroporation provides non-viral gene delivery method for plasmid DNA. Its clinical application was already proven in preclinical and in clinical trial in treatment of melanoma skin metastases with plasmid coding IL-12, in USA. Intratumoral gene transfer of plasmid coding for IL-12 has proven safe end effective, having good local tumour control and some evidence indicates on abscopal effect. The EU directives recommend the use of plasmids without the gene for antibiotic resistance. For this purpose we constructed plasmid coding for IL-12 in accordance with the EU regulatory requirements.
In the proposed study we intend to study the safety and tolerability of the constructed plasmid, phIL12, in treatment of basal cell carcinomas in patients with operable tumors in head and neck region. The study is designed as exploratory, dose escalating with the aim to determine the dose of plasmid that produces IL-12 expression in the tumours with best biological activity, infiltration of the immune cells and no toxicity.

入选标准
- •Histologically or cytologically confirmed, previously untreated cutaneous basal cell carcinoma located in head and neck region.
- •Solitary tumors, with largest diameter up to 3 cm, in the region where curative surgery is feasible.
- •Age 18-years or older.
- •Life expectancy > 3 months.
- •Physical performance in accordance with the Karnofsky scale ≥ 70 or < 2 in accordance with World Health Organization (WHO) scale.
- •The patient must be capable of understanding the treatment procedure and possible adverse events, which may arise during treatment.
- •The patient must be capable of signing the informed consent to participate in the clinical study (voluntary and conscientious consent after education).
- •Prior to inclusion in the trial, the patient must be presented at a multidisciplinary advisory team meeting.
排除标准
- •Known malignancy elsewhere in/on the body.
- •Lesions not suitable for treatment with GET (invasion into the bone, infiltration of large vessels).
- •A life-threatening infection and/or severe heart failure and/or liver failure and/or other life-threatening systemic diseases.
