Phase II Investigation of Calcium Electroporation as a Treatment for Cutaneous and Subcutaneous Malignant Tumours.
This will be a non-randomized phase II trial with the objective of evaluating the clinical response rate of calcium electroporation treatment of malignant tumours of the skin and assessing treatment impact on quality of life. This study will investigate the response rate of calcium electroporation treatment of skin metastases and malignant wounds in a real-world setting, in three different cancer centres in Northern Europe. The centres aim to treat a total of 30 patients with cancer in the skin of any histology. The patients will be treated once and followed with regular examinations for 12 months, starting from first treatment day. 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.
The primary endpoint of this study is to evaluate the clinical overall response rate of calcium electroporation treatment of malignant tumours of the skin after two months. A subset of patients will undergo MR scans after treatment and another subset of patients will be interviewed regarding treatment impact on quality of life.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Calcium electroporation treatment | Experimental | Experimental treatment with calcium electroporation for malignant cutaneous and subcutaneous tumours |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Calcium electroporation | Combination Product | Patients with cutaneous or subcutaneous malignant tumours will be treated with calcium electroporation, i.e. intratumoral injection of calcium followed by electroporation by electric pulses applied directly to the tumor. |
| Measure | Description | Time Frame |
|---|---|---|
| Tumour response (size) | Response rate will be defined as number of responding lesions (partial or complete response) relative to treated lesions evaluated by changes in size (mm) by clinical examination with caliper measurement. Tumor response will be further documented using clinical photography. | 2 months |
| Measure | Description | Time Frame |
|---|---|---|
| Treatment response up to 12 months (size) | Evaluate treatment response at month 1, 3, 4, 6 and 12 in addition to evaluating treatment response after 2 months. Response rate will be defined as number of responding lesions (partial or complete response) relative to treated lesions evaluated by changes in size (mm) by clinical examination with caliper measurement. Tumor response will be further documented using clinical photography. |

| 13 months |
| Assessment of residual tumor from biopsies after 1 year | Assess tumour and surrounding tissue response to treatment from biopsies of the treated area after 1 year. Microscopy assessment of histopathological regressive changes (eg. % tumor cells and fibrosis). | 12 months |
| MRI scans to verify treatment and evaluate tumour changes after treatment | Assess response after treatment on MRI scans on a subset of patients before and immediately after treatment, as well as after 2 months using diffusion-weighted magnetic resonance imaging (DW-MRI) as a method to monitor electroporated tissue, using the concept of the apparent diffusion coefficient (ADC). | 2 months |
| Evaluation of patient quality of life before and after treatment using EORTC Questionnaires. | Evaluate patient quality of life before treatment, after 2 months and after 1 year through EORTC QLQ-C15-PAL Core questionnaires evaluating cancer-related symptoms on a scale from 1-4 (not at all-very much) as well as overall quality of life on a scale from 1-7 (very poor-excellent). | 13 months |
| Systemic immunologic response evaluated by routine scans | Investigate any sign of systemic immunologic response from any routine scans (MRI, PET-CT etc.) before and after treatment in the inclusion period by tumor size and TNM stage. | 12 months |
| Response according to tumour histology | To list response rates and response duration according to tumour histology. | 12 months |
| Remission | To determine complete and partial remissions for all tumours treated. Response rate will be defined as number of responding lesions (partial or complete response) relative to treated lesions evaluated by changes in size (mm) by clinical examination with caliper measurement. Tumor response will be further documented using clinical photography. | 12 months |
| Individual response | To determine rate of response for each individual patient. | 12 months |
| Importance of irradiation | To investigate response (overall, as well as complete and partial) depending whether the treated tumour was in a previously irradiated area. Response rate will be defined as number of responding lesions (partial or complete response) relative to treated lesions evaluated by changes in size (mm) by clinical examination with caliper measurement. Tumor response will be further documented using clinical photography. | 12 months |
| Current measurement | To measure current during treatment as measured by the pulse generator. | 1 day |
| Evaluation of changes in quality of life through qualitative interview | Analyses of qualitative interviews (in a subset of patients) performed before- and 2 months after treatment that include measures related to patient experience and impact on quality of life. | 2 months |
