How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

Investigator standing0/100
No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Summary

The GORE Tissue Reinforcement for Breast Reconstruction (TRBR) research study will look at breast reconstruction during mastectomy procedures. There will be two arms in this study, a Treatment Arm, where data will be collected for a new medical device called the Tissue Reinforcement for Breast Reconstruction (TRBR) Device and a Control Arm where data will be collected from subjects who have previously had surgery and received no additional tissue reinforcement in their breast reconstruction surgery. This research study will look at the safety of the Study Device and the success of the participants breast reconstruction. The Study Device is investigational, which means it has not yet been used nor approved by the FDA for this treatment. The data collected in this study will be compared to the data collected in the Control Arm.

Ages	22 Years – No maximum
Healthy volunteers	No

Eligibility as written in the registry

Inclusion Criteria: 1. Female subjects ≥ 22 years of age. 2. First-time breast reconstruction post-mastectomy for target breast(s). 3. Scheduled to undergo unilateral or bilateral mastectomy with immediate, two-stage, implant-based, subpectoral or prepectoral breast reconstruction after mastectomy. 4. Mastectomy performed to address breast cancer or for cancer prophylaxis. 5. An informed consent form is signed by Subject or Legally Authorized Representative (LAR). 6. Subject is capable of following protocol procedures and complying with follow-up visit requirements Exclusion Criteria: Baseline Exclusion Criteria 1. Subject has had a revision(s) in the target breast(s) following complications of breast augmentation, mastopexy (breast lift), or breast reduction. 2. Subject has undergone previous radiation therapy to the reconstruction site or chest wall. 3. Subject has had chemotherapy within 3 weeks prior to the index procedure. 4. Subject has been treated for a systemic infection or local infection at the surgical site within 30 days prior to index procedure. 5. Subject has a current or previous diagnosis of Methicillin-resistant Staphylococcus aureus (MRSA). 6. Subject has a BMI \> 35. 7. Subject has a known diagnosis of diabetes with a HbA1c \> 7.0mmol/L within 30 days of the Index procedure (i.e., TE placement). 8. Subject was a current or former tobacco/nicotine user, within 90 days prior to Index Surgery (i.e., TE placement). 9. Subject is currently taking medication (e.g., systemic steroid), which in the investigator's opinion, may increase the risk of local complications of breast reconstruction. 10. Subject has other medical, social, or psychological conditions which could interfere with provision of informed consent, completion of tests, therapy, or follow-up. 11. Subject is currently participating in or planning to participate in another investigational drug, biologic or medical device study that may interfere with compliance of TBR 22-07 study requirements or may confound TBR 22-07 study data/outcomes. 12. Subject requires a surgical technique requiring flap (autologous tissue). 13. Subject is pregnant or lactating at the time of the index procedure (i.e., TE placement) or is planning to become pregnant prior to the Exchange procedure. Intraoperative Index Procedure Exclusion 14. Based on investigator's opinion, subject has unsuitable tissue integrity for immediate 2-stage breast reconstruction or is no longer a candidate to receive the TRBR Device (will be recorded as a screen failure). 15. Subject receives an Acellular Dermal Matrix (ADM) or mesh that is not the TRBR Device in the target breast(s)
