About this study

Official title: Phase II Investigation of the Histopathologic Effect of Calcium Electroporation on Cancer in the Skin (CAEP-B)

In this phase II study we investigate the effect of calcium electroporation on cancer in the skin investigated by histopathology.

Read the detailed description

In this non randomized phase II study, we will explore histopathological tumour cell death mechanisms in 24 patients with breast cancer metastases or other cutaneous or subcutaneous malignancy. The primary endpoint of the biopsy study is to evaluate differences in tumour infiltrating lymphocyte (TIL) population in tissue samples from treated cancer tumours two days after calcium electroporation treatment compared to samples taken on the day of treatment before the calcium electroporation procedure. TIL content in biopsies will be evaluated by pathological examination and specified in percent of cells. Patients will be followed up to 3 months and depending on number of treated tumors, biopsies will be taken at different timepoints after one or two treatments with calcium electroporation. Other analyses will include differences regarding tumour type, immune marker expression levels over time, vascular effects and regressive changes as well as examining changes in systemic immunological markers.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The effect of calcium electroporation on tumor infiltrating lymphocyte (TIL) population.

    The primary endpoint of this study is to evaluate differences in TIL population in tissue samples from treated cancer tumours two days after calcium electroporation treatment compared to before treatment (biopsy taken on the day of treatment before the calcium electroporation procedure). TIL content in biopsies will be evaluated by pathological examination and expressed as percent of cells.

    Measured: 2 days

Secondary outcomes (23)

  5. TIL population and tumour type

    To describe any relation between change in TIL population (percentage of cells) and tumour type before and after calcium electroporation.

    Measured: 3 months

  6. Tumour regression

    To describe presence of regressive changes including necrosis at different timepoints (percentage of tissue).

    Measured: 3 months

  7. Residual tumour

    To describe presence of residual tumour (yes/no) and description of topographical location.

    Measured: 3 months

  8. Vascular effects

    To investigate vascular effects of calcium electroporation including changes in capillary structures by histochemical staining for endothelial biomarkers CD31 and/or CD34.

    Measured: 3 months

  9. Clinical response to intervention

    To document evolution of tumours before and after treatment using digital photography including a ruler.

    Measured: 3 months

  10. Complete response at patient level

    To sum number of patients with complete response after one or two treatments, respectively. Complete response will be defined as disappearance of all target lesions.

    Measured: 3 months

  11. Complete disappearance of treated lesions (in relation to all lesions treated)

    To sum number of lesions across all patients with complete remission after one or two treatments, respectively (expressed at percentage of all treated lesions).

    Measured: 3 months

  12. Tumour type

    To establish number of treated tumours with complete response depending on tumour type.

    Measured: 3 months

  13. Systemic immunologic response

    To detect signs of systemic immunologic response from any routine scans before and after treatment in the inclusion period.

    Measured: 3 months

  14. Importance of previous irradiation

    To investigate differences in effect depending whether the treated tumour was in a previously irradiated area.

    Measured: 3 months

  15. Adjacent non-tumour tissue

    To evaluate effect on adjacent non-tumour tissue.

    Measured: 3 months

  16. PD-L1 expression over time

    To assess PD-L1 expression over time by biopsy.

    Measured: 3 months

  17. Relation between change in PD-L1 expression and response

    To investigate any relation between change in PD-L1 expression and tumour response.

    Measured: 3 months

  18. PD-L1 expression in relation to cell types

    To describe PD-L1 expression in relation to cell types found in the tumour environment

    Measured: 3 months

  19. PD-L1 expression of different tumour histologies

    To describe PD-L1 expression on different cell types of the different tumour histologies investigated.

    Measured: 3 months

  20. Western blotting

    To examine frozen tissues samples by western blotting in order to support any of the above mentioned endpoints.

    Measured: 3 months

  21. Systemic immune factors after calcium electroporation

    Blood samples may be analyzed for NK cell- and T-cell gene expression levels. Levels before and after treatment will be compared.

    Measured: 3 months

  22. Current measurement

    To measure current during treatment as indicated by the pulse generator.

    Measured: 1 month

  23. PCR

    To examine frozen tissues samples by PCR. Relevant gene expression will be compared before and after treatment in breast cancer and non breast cancer samples.

    Measured: 3 months

Model description
Prospective phase II clinical study: Patients with cutaneous metastases will be recruited at the Department of Oncology, Zealand University Hospital (ZUH). One cohort of 24 patients with respectively disseminated breast cancer or other solid tumour malignancies, will be included. This will be a non-randomized trial. 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 and patients with over 3 metastases will be offered retreatment of some of their metastases. A maximum of 2 treatments per patient will be conducted with an interval of minimum 4 weeks. The patients will be followed with regular examinations for 3 months, starting from first treatment day.

The record says: finished, as of the sponsor's last update on 3 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The effect of calcium electroporation on tumor infiltrating lymphocyte (TIL) population. (time frame: 2 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Oct 2023.
