About

In this phase I study 6 patients with inoperable colorectal cancer is treated with calcium electroporation to establish safety and efficacy of the treatment.

Full description

A total of 6 evaluable patients with inoperable colorectal cancer are expected to be included in the study and the time for inclusion of patients is estimated to be 1-2 years. All patients will have been offered the standard of care and all available alternatives before entering the protocol. Calcium electroporation will not be compared to other means of treatment.

All patients will be treated once, but in case of residual tumor tissue at follow-up, and if the investigator considers it safe, they will be offered re-treatment. A maximum of 3 treatments per patient will be conducted with an interval of minimum 4 weeks. The patients will be followed with regular examinations for 12 months, starting from first treatment day.

Inclusion criteria

Histologically verified colorectal tumor
Conferred by multidisciplinary team (radiologists, surgeons and oncologists) discussing options possible for the patient, resulting in agreement that an endoscopic treatment with calcium electroporation should be offered to the patient.
Treatment free interval of minimum 2 weeks.
Thrombocytes ≥ 50 billions/l, INR >1,2. Medical correction is allowed, e.g. correction of elevated INR by means of vitamin K.
Performance status ECOG/WHO ≤2

Trial subject ≥ 18 years.
Trial subject must be able to understand the participants' information.

Exclusion criteria

Concurrent participation in other clinical trials that involve experimental drugs or participation in a clinical trial involving experimental drugs within 4 weeks prior to administration of the drug in this study.
Treatment with bevacizumab within the last 4 weeks.
