REGENERA Implant in Excised Non-Malignant Breast Lesions

N/ACompletedNCT04131972

Tensive SRL15 enrolled

Overview

The purpose of this First-in-Human pilot study is to evaluate the safety and performance of REGENERA breast implant in a selected cohort of patients with non- malignant breast lesions treated with excision or lumpectomy in whom the tissue removed is replaced by REGENERA.

This is a pre-market, single center, interventional, open label, non-comparative, pilot first-in-human study on adult female patients with localized non-malignant breast lesion. This study will include an enrollment period of 12 months and 6 months study duration per patient. The primary objective of this study is to demonstrate the safety profile of a new breast implant (REGENERA) in excision or lumpectomy of non-malignant breast lesions. The secondary objectives of this study are: * To assess the safety of the implant procedure * To assess the feasibility of the implant procedure * To evaluate the performance of REGENERA breast implant: * In replacing the removed tissue * In potential interference with current diagnostic standard of care imaging procedures * On patient's quality of life and satisfaction * On investigator's satisfaction.

Outcomes

Primary Outcomes

Cumulative number of all Serious Adverse Events

Cumulative number of Serious Adverse Events collected throughout the study and associated with the REGENERA implant device (Adverse Device Effects)

Time frame: at 6 months from implantion of the device

Secondary Outcomes

Measurement of changes in breast appeareance before and after surgery through antropomorphic chest parameters

Assess breast appearance before and after surgery with photo and chest measurement. In particular, the following measures, in cm, will be evaluated: sternal notch to nipple (SN), nipple to inframammary fold (NF), nipple to sternum (NM), the areola diameter and the ptosis grade.

Time frame: at 2 weeks before the implantation of the device (Day 0), 1 week from Day 0, 3 months from Day 0, 6 months from Day 0

Measurement of the reduction of reliability of the currently used diagnostic imaging techniques

Assess the potential interference with current, standard- of-care imaging techniques by evaluation of the following factors: (1) for ultrasound, the possible attenuation of the acoustic beam preventing the visualization of the tissue behind the implant; (2) for magnetic resonance imaging, possible creation, caused by the implant, of images mimicking a pre-invasive or invasive lesion.

Time frame: at 1 week from the implantation of the device (Day 0), 2 weeks from Day 0, 1 month from Day 0, 3 months from Day 0 and 6 months from Day 0

Patient Quality of Life measured through Breast-Q questionnaire

Measure changes in patient's Quality of Life (QoL) and satisfaction through Breast-Q™ questionnaire (pre- and post-operative Breast Conserving Therapy (BCT) module version 2.0) after surgery versus baseline (prior implantation surgery). Breast-Q™ questionnaire includes 7 scales measuring (i) breast satisfaction, (ii) psychosocial well-being, (iii) physical breast well-being, (iv) sexual well-being, (v) patient experience satisfaction with the surgeon, (vi) patient experience satisfaction with the medical equip and (vii) patient experience satisfaction with the hospital staff. Each scale is evaluated by defined questions where the patient has to answer by a numeric scale. For example: "1", "non of the time"; "2", "a little of the time"; "3", some of the time; "4", "most of the time"; "5", "all of the time". Once the questions are answered, a conversion table is applied to convert the raw scale summed score into a score from 0 (worst) to 100 (best).
