Study Description

Brief Summary:

The aim of this study is to investigate whether the application of concomitant modulated electro-hyperthermia in a neoadjuvant chemotherapeutic setting is beneficial for patients with HER2-negative, stage II-III breast cancer.

Condition or disease	Intervention/treatment	Phase
HER2-negative Breast Cancer	Device: Oncotherm EHY-2030; Drug: Paclitaxel; Drug: Carboplatin; Drug: Cyclophosphamide/Doxorubicin; Procedure: Breast cancer removal surgery	Phase 2; Phase 3

Detailed Description:

This study is a pivotal, randomized (1:1), open-label, two-treatment group, single-centre trial of Oncotherm EHY-2030, a modulated electro-hyperthermia (mEHT) device. Female patients aged 18 years or older with locally advanced, unilaterally localized HER2-negative breast cancer requiring neoadjuvant treatment are eligible for the study.

In the study, the wTAX (+ carboplatin) +AC neoadjuvant chemotherapy protocol will be administered according to the routine daily regimen, with or without mEHT three times a week during the wTAX (+ carboplatin) period. Carboplatin will be administered for patients with triple-negative breast cancer only.

Primary objective: to compare whether the percentage of tumor size decrease determined by imaging techniques is different in the two treatment groups?

Secondary and other objectives:

• Is complete pathological response (pCR) more common in the mEHT-treated group?
• Does the pattern of treatment response (pCR : pPR : pNR) differ between the two groups?
• Is the quality of life of patients different in the two study groups?
• Is there any treatment-related changes in the routine laboratory parameters such as blood count, liver enzymes, renal function? And do these differ in the two study arms?
• Safety and tolerability analysis of the device.

Arms and Interventions

Arm	Intervention/treatment
Active Comparator: wTAX (+ carboplatin) +AC; wTAX: Weekly paclitaxel (+ carboplatin in the case of triple-negative breast cancer) for 12 weeks; AC: Doxorubicin/Cyclophosphamide every three-weeks, 4x; Breast cancer tumor removal surgery (if feasible)	Drug: Paclitaxel; weekly paclitaxel for 12 weeks; Drug: Carboplatin; added to weekly paclitaxel if patient has triple-negative breast cancer; Drug: Cyclophosphamide/Doxorubicin; according to the AC protocol; Procedure: Breast cancer removal surgery; Either breast-conserving surgery or total mastectomy after the neoadjuvant chemotherapy with or without mEHT (if feasible)
Experimental: wTAX (+ carboplatin) +AC + mEHT; wTAX + mWEHT wTAX: Weekly paclitaxel (+ carboplatin in the case of triple-negative breast cancer) for 12 weeks mEHT: Concomitant modulated electro-hyperthermia using the Oncotherm EHY-2030 device, 3 times per week, for 12 weeks; AC: Doxorubicin/Cyclophosphamide every three-weeks, 4x; Breast cancer tumor removal surgery (if feasible)	Device: Oncotherm EHY-2030; Oncotherm EHY-2030 is a non-invasive electromagnetic devices with known anti-tumoral effects. It operates in a precision capacitive coupled impedance matched way, working on a radiofrequency of 13.56 MHz. mEHT exploits various biophysical differences of cancer cells. For example, energy absorption on the membrane rafts is different than those of healthy host cells, and damage-associated molecular patterns (DAMPS) will also occur leading to programmed or immunogenic tumor cell death. mEHT can enhance DNA fragmentation of tumor cells, increase the fraction of cells with low mitochondrial membrane potential, increase the concentration of intracellular Ca2+, increase the Fas, c-Jun N-terminal kinases and MAPK/ERK signaling pathways, increase the expression of pro-apoptotic Bcl-2 family proteins and can up-regulate the expression of genes associated with the molecular function of cell death (EGR1, JUN, and CDKN1A) and silencing others associated with cytoprotective functions.; Drug: Paclitaxel; weekly paclitaxel for 12 weeks; Drug: Carboplatin; added to weekly paclitaxel if patient has triple-negative breast cancer; Drug: Cyclophosphamide/Doxorubicin; according to the AC protocol; Procedure: Breast cancer removal surgery; Either breast-conserving surgery or total mastectomy after the neoadjuvant chemotherapy with or without mEHT (if feasible)

Outcome Measures

Primary Outcome Measures :

1. Residual size of the primary tumor, determined by imaging techniques (in percentage) [ Time Frame: change from baseline at 6 months ]

   Using breast MR measurements, the the residual size of the primary tumor will be specified for all patients (in percentage). The comparison of these between the two study arms will serve as the primary outcome measure.

   Calculation: The tumor size after the 6-months treatment period (in mm) will be divided by the size measured prior treatment (in mm). The quotient will be given as a percentage and subtracted from 100.

3. Comparison of surgical procedure ratios [ Time Frame: 9 months ]
   It will be compared whether the ratio of two main breast surgery types (breast-conserving surgery vs. total mastectomy) differ between the two study arms.
4. Effect of treatment on white blood cell counts [ Time Frame: through study completion, an average of ~8 months ]
   White blood cell counts (in G/L) will be measeured at every patient visit, and their longitudinal change will be analyzed using mixed-effect statistical modeling techniques.
