About this study

Official title: A Randomized Pivotal Clinical Trial In Breast Cancer Patients Of Pre-Operative Focal Microwave Thermotherapy Treatment For Early-Stage Breast Disease In Intact Breast

RATIONALE: Microwave thermotherapy kills tumor cells by heating them to several degrees above body temperature.

PURPOSE: Randomized phase II trial to compare the effectiveness of microwave thermotherapy before surgery to that of surgery alone in treating women who have stage I or stage II breast cancer.

Read the detailed description

OBJECTIVES:

  • Compare the safety and efficacy of preoperative focused microwave thermotherapy followed by surgery vs surgery alone in women with early-stage primary breast cancer.
  • Compare the reduction of tumor cells at surgical margins and second incision rates in women treated with these regimens.
  • Compare the percentage of pathological cell death in women treated with these regimens.
  • Compare the amount of surgically removed breast and tumor tissue in women treated with these regimens.
  • Compare the measurement of the extent tumor margins of the surgically removed breast and tumor tissue in women treated with these regimens.

OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to tumor classification (T1 vs T2) and participating center. Patients are randomized to 1 of 2 treatment arms.

  • Arm I:Patients undergo ultrasound-guided placement of a microwave sensor and a temperature probe (before or after compression of the breast) and external placement of 2 large opposing microwave emitters and up to 7 skin temperature sensors on the compressed breast. Patients then receive focused microwave thermotherapy that slowly heats the primary breast tumor and deep proximal breast tissue. In the absence of undue heating of the skin, a tumor temperature of 48-52° C is targeted and maintained for an equivalent thermal dose of 140-180 minutes.

Within 60 days of thermotherapy, patients undergo lumpectomy.

  • Arm II: Patients undergo lumpectomy only. Patients are followed at 30 and 90 days after surgery, and then at the discretion of the physician.

PROJECTED ACCRUAL: A total of 200-222 patients (100-111 per treatment arm) will be accrued for this study.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing conventional surgery, neoadjuvant therapy and thermal ablation therapy in people with Breast Cancer, run by Imunon at 8 sites in 2 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 6 Nov 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States, United Kingdom. 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?

Results are not available in the source record.

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.

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 6 Nov 2013; AzTrials last refreshed its copy on 26 Oct 2026.
