REGENERA Implant in Excised Non-Malignant Breast Lesions

Not Applicable

Completed

• Conditions: Benign Breast Disease
• Interventions: Device: REGENERA

• Registration Number: NCT04131972
• Lead Sponsor: Tensive SRL

Brief Summary

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.

Detailed Description

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.

Study & Design

• Study Type: INTERVENTIONAL
• Study Design: SINGLE_GROUP

Arm && Interventions

Group	Intervention	Description
Single arm 1	REGENERA	Each patient will be planned to perform 7 study visits and at the second visit excision / lumpectomy and REGENERA implant will be performed during the same surgical intervention.

Primary Outcome Measures

Name	Time	Method
Cumulative number of all Serious Adverse Events	at 6 months from implantion of the device	Cumulative number of Serious Adverse Events collected throughout the study and associated with the REGENERA implant device (Adverse Device Effects)

Secondary Outcome Measures

Name	Time	Method
Patient Quality of Life measured through Breast-Q questionnaire	at 1 month from the implantation of the device (Day 0), 6 months from Day 0 versus 2 weeks before Day 0	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).
Cumulative number of all Adverse Events associated with the surgical procedure	at 6 months from the implantation of the device	Cumulative number of all Adverse Events associated with the surgical procedure: number of re-operations and / or explants due to seroma, hematoma, infection, wound dehiscence, skin retraction, acute inflammatory reactions, allergic reactions to the device, persistent pain.
Measurement of changes in breast appeareance before and after surgery through antropomorphic chest parameters	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	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.
Measurement of the reduction of reliability of the currently used diagnostic imaging techniques	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	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.
Patient pain measurement through a Visual Analogue Scale	at 2 weeks before the implantation of the device (Day 0), Day 0, 1 week from Day 0, 2 weeks from Day 0, 1 month from Day 0, 3 months from Day 0 and 6 months from Day 0	Assess pain intensity with a Visual Analogue Scale (VAS) at each study visit. The VAS measure will be made through a cross (X) that the patient has to put along a bar. The left margin of the bar corresponds to "no pain" (0 score) and the right margin to "worst pain" (10 score).
Measure of the Investigator's satisfaction on the implantation procedure, through a Visual Analogue Scale (VAS) and an ad-hoc questionnaire	implantation satisfaction (VAS + ad-hoc questionnaire) at the implantation of the device (Day 0) and REGENERA performance (VAS) at 6 months from Day 0	Assess investigator's satisfaction on the implantation procedure, through a Visual Analogue Scale (VAS) and an ad-hoc questionnaire (developed by the Sponsor), and on the REGENERA performance, through a VAS scale.; The VAS measure will be made through a cross (X) that the patient has to put along a bar. The left margin of the bar corresponds to "no pain" (0 score) and the right margin to "worst pain" (10 score).; The ad-hoc questionnaire has a unique scale made of 5 levels (1 corresponds to "strongly disagree" and 5 corresponds to "strongly agree") to be used for each question. As there are 12 questions, 12 is the minimum score and 60 is the maximum score as a sum of all answers.
