Confirmatory Clinical Evaluation of Novilase® Laser Therapy for Focal Destruction of Malignant Breast Tumors
Study Details
Study Description
Brief Summary
Prior to this confirmatory pivotal study, the multicenter Br-002 feasibility study was completed. 98% of tumors less than or equal to 15mm were completely ablated in one procedure.This study will evaluate Novilase for the focal destruction of malignant tumors of the breast that are less than or equal to 15 mm against a performance goal for the standard of care, lumpectomy. The ASBrS' goal of less than 20% retreatment by 2020 was selected as a representative performance goal, i.e., 80.0%, and is consistent with published effectiveness rates for lumpectomy.

Detailed Description
Subjects with biopsy-diagnosed malignant breast tumors less than or equal to 15 mm will be invited to participate. Subjects will receive a screening MRI and if eligible will then have laser ablation, followed by MRI and an excision at 4-6 weeks following the laser procedure. This study will be deemed successful if the lower limit of a 95% confidence interval for the proportion of patients who have complete tumor ablation with one Novilase laser ablation procedure at 4-6 weeks post-procedure is greater than the performance goal. Specifically, Novilase will have demonstrated success if the complete tumor ablation rate is greater than 87.85%.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Novilase Laser Ablation and excision Eligible subject will receive image-guided laser ablation of a targeted malignant breast tumor. At 4-6 weeks following the ablation, she will receive a MRI and excision. Pathology and MRI will determine rate of complete ablation. Subject is expected to proceed with radiation and/or adjuvant therapy per standard of care. |
Device: Novilase Laser ablation
Image-guided, percutaneous laser ablation of breast tumors

Outcome Measures
Primary Outcome Measures
- Percentage of target tumors completely ablated in one procedure [4-6 weeks]
Efficacy: Rate of complete ablation by Novilase laser ablation
- Frequency of adverse events (categorized using the NCI Common Terminology for Adverse Events (CTCAE) v4.0 guidelines) post-laser ablation and post-surgery [4-6 weeks]
Safety: frequency of AEs
Secondary Outcome Measures
- Patient reported rate of return to activities of daily living post-laser ablation and post-surgery [4-6 weeks]
Rate of recovery
- Physician reported cosmetic satisfaction, utilizing the 4-point scoring system of breast cosmesis in protocol (e.g., excellent, good, fair, poor) post-laser ablation and post-surgery (4-6 weeks) [4-6 weeks]
Post-procedure cosmetic satisfaction
- Health related quality of life outcome measures at three timepoints via EORTC QLQ-C30 & QLQ-BR23 questionnaire (baseline and 4-6 weeks post-laser ablation and post-surgery) [4-6 weeks]
Health-related quality of life outcome measures

-
Tumor is well visualized on MRI
-
Subject with mammographic appearance of overall dense parenchymal tissue may be included, as long as a clearly evident marker is present at tumor site
-
Tumor with less than 25% intraductal component, as determined by core biopsy
-
No clinically significant co-morbidities (e.g., chronic illnesses existing simultaneously with and usually independent of breast cancer) that affect life expectancy
-
Subject weight limited to ≤300 lbs. or ≤136 kg
-
Subject agrees to comply with standard of care radiation or adjuvant therapy as prescribed by physician
Exclusion Criteria:
-
Subject younger than 18 years of age

-
Contraindications to MRI according to site guidelines (e.g., cardiac pacemaker, metallic implants)
-
History of severe asthma
-
