Adding TheraBionic P1 radiofrequency therapy to treatment for early-stage HR+ HER2- breast cancer

Official title: A Window of Opportunity Pilot Study: TheraBionic P1 Device for Patients With Resectable Early-stage Breast Cancer in a Neoadjuvant Setting

Run by Barbara Ann Karmanos Cancer Institute · NCT07218432 · Data updated 2026-11-12

This study will try giving TheraBionic P1 amplitude-modulated radiofrequency therapy before surgery to see if it improves tumor response in women with early-stage, hormone receptor–positive, HER2-negative breast cancer.

Is this trial a fit for you?

Likely a good fit

Women aged 22 or older with histologically proven invasive, early-stage (stage I–II or selected stage III planned for upfront surgery) HR-positive, HER2-negative breast cancer who can undergo at least two weeks of device treatment and provide archival tissue.

Probably not a fit

Patients with HER2-positive or HR-negative tumors, metastatic disease, those not planning upfront surgery, or those unable to attend the treatment visits are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants with operable early-stage, hormone receptor–positive, HER2-negative breast cancer will receive TheraBionic P1 amplitude-modulated radiofrequency electromagnetic field treatment for at least two weeks prior to their planned definitive surgery. The device therapy is added to standard clinical management with the main outcome being the pathological response measured at resection. The trial is interventional and conducted at multiple sites within the Karmanos Cancer Institute network in Michigan. Archival tumor tissue is required and patients must be able to provide informed consent.

Why it matters

Potential benefit: If effective, adding this device before surgery could increase the amount of tumor killed prior to resection and reduce residual disease.

How similar studies have gone: Small pilot and early-phase studies of amplitude-modulated radiofrequency approaches have reported limited signals of activity, but device-specific evidence in early-stage breast cancer is sparse and not yet conclusive.

Who can join: the full rules

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Participant must have histologically proven invasive breast cancer that is HR (hormone receptor) positive and HER2 (Human Epidermal Growth Factor Receptor 2) negative according to the 2010 American Society of Clinical Oncology (ASCO) College of American Pathologists (CAP) guidelines (ER and/or PR (progesterone receptor) \>1% and HER2 negative by immunohistochemistry \[IHC\] and/or fluorescent in situ hybridization \[FISH\]).
* Participant must have early-stage operable disease (stage I-II or III who have planned upfront surgery) and agree to definitive upfront surgery.
* Participant must be available for at least two weeks of TheraBionic treatment prior to scheduled resection
* Participant must have archival tissue available.
* Participant must be a woman aged 22 years or older
* Participant must be able to understand a written informed consent document and be willing to sign it
* Participant must have an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2.
* It is not known what effects this treatment has on human pregnancy or development of the embryo or fetus. Therefore, women of child-bearing potential must agree to avoid becoming pregnant starting at initiation of treatment up until at least 30 days after the last TheraBionic P1 session

Exclusion Criteria:

* Participants that are receiving or will receive neoadjuvant chemotherapy or neoadjuvant hormonal therapy
* Participants with known active secondary malignancy, unless, in the opinion of the investigator, it is unlikely to interfere with the safety and efficacy of the endpoints
* Participants that are taking any other investigational drugs
* Participants that are pregnant or breastfeeding due to the unknown but potential risk for adverse events. If a breastfeeding participant would like to be part of this study, breastfeeding must be discontinued
* Participants with active oral mucosal inflammation, ulceration, or other pathology that could interfere with the use of TheraBionic P1 device (for example: mucositis, thrush, bleeding mucosal lesions, oral herpes, aphthous stomatitis, mouth ulcers, chancre sores, gingivostomatitis, herpangina, aphthae).
* Participants receiving calcium channel blockers and any agent blocking L-type or T-type voltage gated calcium channels (for example: amlodipine, nifedipine, ethosuximide, ascorbic acid/vitamin C, etc.) unless their medical treatment is discontinued at least one day prior to treatment. Participant must agree to abstain from using calcium channel blockers for the duration of treatment on study.
* Participants that do not agree to be followed according to the study protocol or have cognitive or physical inability to use the device
* Participants with a known severe (e.g., anaphylactic) allergy to nickel.
