Clinical Trial Summary

Using moderate whole-body hyperthermia (mWBH) in tumor patients to see the influence on circulating tumor cells, tumor response, quality of life, fatigue, psyche, immune response and tumor microenvironment

Description:

Moderate whole-body hyperthermia (mWBH) is considered to be a very well-tolerated treatment. It has been used in numerous naturopathic and oncological practices for decades. It is also being used more and more with an increasing number of non-oncological diseases. A recently published randomized study was able to prove a sustained positive effect of whole-body hyperthermia in patients with depressive episodes. However, there are no clinical studies that demonstrate the benefit of this measure with regard to oncological treatment. There is also a lack of clarity about the mechanism of action of mWBH. A positive modification of the tumor microenvironment (increased perfusion, reduced interstitial pressure) and an increased activation of tumor-killing immune cells could be shown preclinically - however, a clinical evaluation of these mechanisms has not yet taken place.

This randomized study aims to evaluate the effect of mWBH on the tumor response of patients suffering from advanced cancer. The aim of the study is to demonstrate an improvement in the therapy response rate three months after the end of therapy through the additional use of mWBH, measured by a positive influence on the change in the number of circulating tumor cells from the time before therapy to the time three months after the start of therapy.

Quality of life reported by patients, recorded by the FACT-G questionnaire, as well as psychological parameters, fatigue and various other parameters with regard to an increase in the effect on the tumor are evaluated as secondary endpoints. All patients also receive serial immune monitoring. For this purpose, blood samples are taken before therapy and several times during the course of the therapy, which are then evaluated with regard to cytokines, immunological proteins and specific subgroups of immune cells.

The patients all receive guideline-based therapy in line with current internal practice. In addition to standard therapy, patients are randomized 1:1 and, if randomized to the mWBH arm, receive an additional 3-4 mWBH sessions during their oncological treatment. A total of six different patient groups are included, all with palliative therapy intentions (patients with multiple metastatic malignant melanoma before initiation of immunotherapy (checkpoint blockade), patients with metastatic or inoperable pancreatic carcinoma for whom first-line chemotherapy with FOLFIRINOX is planned, patients before palliative radiation therapy for a hormone-receptor-positive breast cancer who have previously received palliative systemic therapy and have at least one other tumor lesion in addition to the one that was irradiated, patients with metastatic sarcoma in whom ablation of the metastases is not possible and who are receiving palliative first-line therapy using Doxorubicin is planned to treat patients with metastatic or loco-regionally recurrent HPV-associated squamous cell carcinoma of the head and neck region, cervix, anus or vulva, for whom no local therapy methods are possible and palliative first-line platinum therapy is planned, patients with metastatic castration-resistant prostate cancer with progressive disease after exhaustion of recommended therapy options for whom a therapeutic trial with lutetium-177-PSMA has been indicated). A total of at least 72 patients, stratified into the 6 subgroups mentioned above, should be evaluated in the study, who should receive three to four sessions of mWBH in addition to standard oncological treatment. In order to obtain the necessary minimum number of patients in all subgroups, the inclusion of 80 patients in the study is necessary with an expected drop-out rate of 10%.

In order to record the effect of mWBH on quality of life, fatigue and depression, study participants must fill out a questionnaire on quality of life, fatigue and depression before the start of therapy, at the end of treatment and two weeks after therapy. To evaluate the influence of mWBH on immune parameters, patients also receive additional blood samples before the start of therapy, at the end of therapy and at two follow-up times, which can normally be combined with routine blood samples.

For further risk stratification, the samples obtained after an operation or biopsy can be used for further analysis. This examination means no additional intervention and no increased risk for the patient, since these have already been carried out routinely. Patients have the option of expressly agreeing to the removal and further use of these biomarkers or rejecting them as part of the declaration of consent.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	change in the number of circulating tumor cells before therapy vs after therapy	ANCOVA is used as the statistical methodology. The change in the number of circulating tumor cells three months after the start of therapy is the dependent variable, the group (intervention or control) and the number of circulating tumor cells as well as the tumor entity (6 groups) are independent variables. Case number estimation: So far there are no studies that have examined this outcome. We assume that the intervention effect is moderate and that an effect size of 0.6 to 0.7 can be achieved.; If 36 patients per arm are included in the study, an effect size (Cohen's d) of 0.67 or greater at a two-sided significance level of a=0.05 with a power of 80% can be demonstrated using the t-test for independent samples.	Test therapy naive versus three months after the start of therapy
Secondary	Response of the tumors	morphologically in imaging	three months after the start of therapy
Secondary	Quality of life of the patients	The hypothesis is that patients with mWBH report a higher quality of life than patients without mWBH. Life Quality will be assessed in a standardized questionnaire as EORTC QLQ-30	measured before and 2 weeks after the end of therapy (end of therapy is determined as the last planned mWBH session) or at a comparable time in the control group
Secondary	influence of mWBH on depressive/dysthymic moods/episodes as well as on fatigue symptoms	reported by patients in standardized questionnaire	Follow-up visits, in total 2 years follow up time
Secondary	impact of patient-reported organ-specific functional impairment	measured by standardized questionnaires (depending tumor entity e.g. PR25 in patients with prostate cancer, BR23 in breast cancer, MEL38 in melanoma, and PAN26 in pancreatic cancer	Follow-up visits, in total 2 years follow up time
Secondary	influence of mWBH on different leukocyte sub-populations and the plasma concentration of cytokines/proteins, which indicate a suspected predictive effect on the response to immunotherapy.	leukocyte sub-populations are measured by FACS	measurement before treatment compared with the one after treatment
Secondary	side effect profile of mWBH	side effects reported by practitioner and the patient, potential side effects will be documented in Case Report Form (CRF) which will be filled out in follow up visits	during and after treatment in Follow-up visits, in total 2 years follow up time
Secondary	Tumor marker responses in patients who have measurable tumor markers that have previously also been correlated with disease activity	It is assumed that this is the case in a total of 50 patients (ITT) (25 in each group)	measurement before treatment compared with the one after treatment
Secondary	survival rate and rate of progression-free surviving patients across all stratification groups.	PFS = death or any form of tumor recurrence, local or systemic, are counted as an event here	1 and 2-year
Secondary	The impact of mWBH on leukocyte nadir and time to recovery in patients receiving radiation, lutetium, or cytostatic therapy (arms 2-6)	Comparison of routine lab-testing within intervention group and between control	during and after treatment in blood assessment
Secondary	In arm 3 (breast cancer): The influence of mWBH on the occurrence of an abscopal effect, i.e. a response of a tumor lesion outside the irradiated volume (dose < 4 Gray during fractionated palliative irradiation)	Response is evaluated by the RECIST criteria: CR or PR	in follow-up routine imaging controls ( e.g. 3 months after treatment)
