About this study

Official title: A Single-Blinded Randomized Prospective Trial to Compare Outcomes Between Two Acellular Dermal Matrices Used for Immediate, Post-Mastectomy Breast Reconstruction

This study will evaluate the performance of Alloderm RTU medium (LifeCell) vs. Cortiva 1mm Allograft Dermis (RTI Surgical®, Inc.). These are the thinnest versions of acellular dermal matrices (ADM) offered by both vendors and can be used for post-mastectomy breast reconstruction. Alloderm RTU medium has a thickness of 1.6±0.4 mm, while Cortiva 1mm Allograft Dermis has a thickness of 1.0±0.2 mm. In the context of breast reconstruction, these ADMs are used in the same manner. They may be inserted with a tissue expander immediately after skin- or nipple-sparing mastectomy. The investigators will examine breast-reconstruction associated complication rates, pre- and post-operative patient reported outcomes using the Breast Q, and physician reimbursement as well as direct hospital costs. The endpoint will be either exchange of the tissue expander for a permanent breast implant or autologous flap, explantation due to patient preference, development of a complication, or less common reasons. The investigators propose that Cortiva 1mm Allograft Dermis and Alloderm RTU will have equivalent complication and patient reported outcome rates as well as physician reimbursement, but that direct hospital cost will be less with Cortiva 1mm Allograft Dermis.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Incidence of premature tissue expander (TE) removal

    • All participants meeting the eligibility criteria who have signed a consent form and have a skin- or nipple-sparing mastectomy and immediate tissue expander breast reconstruction will be included in the analyses of the primary study endpoint.
    • A breast with the TE removed before planned exchange to a permanent breast implant is considered to have had a premature TE removal

    Measured: Up to 15 months

Secondary outcomes (16)
  1. Patient satisfaction as measured by Breast Q

    • Each domain contains separate modules that investigate physical, psychosocial, and sexual well-being as well as their satisfaction with their care, breasts, and overall outcome.
    • It also investigates patient expectations in the preoperative questionnaire, and degree to which expectations were met in the post-operative version.
    • Each module generates a Q-score on a 0-100 scale that can be used for quantitative analysis to enable statistical comparison of the pre- to the post-operative state.

    Measured: Up to 15 months

  2. Health related quality of life as measured by Breast Q

    • Each domain contains separate modules that investigate physical, psychosocial, and sexual well-being as well as their satisfaction with their care, breasts, and overall outcome.
    • It also investigates patient expectations in the preoperative questionnaire, and degree to which expectations were met in the post-operative version.
    • Each module generates a Q-score on a 0-100 scale that can be used for quantitative analysis to enable statistical comparison of the pre- to the post-operative state.

    Measured: Up to 15 months

  3. Duration of drain use

    -The number of days a drain is used after surgery

    Measured: Up to 15 months

  4. Incidence of analgesic use for pain

    -Outpatient analgesia beyond preoperative analgesic requirements will be recorded, and will include no pain medicine, celecoxib, gabapentin, acetaminophen, hydrocodone, oxycodone, OxyContin, ibuprofen, hydromorphone, cyclobenzaprine, and methadone.

    Measured: Up to 15 months

  5. Incidence of infection as measured by presence or absence of cellulitis

    -The number of participants who experience cellulitis

    Measured: Up to 15 months

  6. Incidence of non-infectious complications

    -These will include seroma (and method(s) of seroma diagnosis), incisional dehiscence, necrosis of the mastectomy skin flap, dehiscence of the ADM from the chest wall or pectoralis muscle, hematoma, or a pathologic (grade III or IV) capsular contracture.

    Measured: Up to 15 months

  7. Nature of second surgery as measured by type of surgery enrolled patients undergo to address their tissue expander after its initial insertion

    -Document type of second surgery each participants has after their initial tissue expander

    Measured: Up to 15 months

  8. Degree of acellular dermal matrices (ADM) incorporation

    -A qualitative scale, from 1-4 will be used to quantity ADM incorporation. This will be recorded upon inspection of the ADM at the time that the tissue expander is readdressed.

    Measured: Up to 15 months

  9. Comparison of direct hospital costs

    -These are available through Barnes hospital and will be normalized to Medicare rates by conversion from relative value units (RVU) due to heterogeneity in payer mix. Line item costs as well as patient-level data will not be available due to the proprietary nature of these products. However, normalized, aggregate patient data for the cycle of care in each study arm (Alloderm RTU vs Cortiva 1mm Allograft Dermis) is available and will be calculated. "Direct costs" are those that can be traced directly to a department, product or service, excluding overhead costs, and thus reflect the hospital's assessment of the cost it incurred providing the specific services and supplies used by the patients. All breast reconstruction related costs performed by Barnes, or Barnes West County hospital from the first surgery up until immediately before the second surgery will be included.

    Measured: Up to 15 months

  10. Comparison of physician reimbursements

    -These are available through the Department of Surgery and will be normalized to Medicare rates by conversion from relative value units (RVU) due to heterogeneity in payer mix. Line item costs as well as patient-level data will not be available due to the proprietary nature of these products. However, normalized, aggregate patient data for the cycle of care in each study arm (Alloderm vs Cortiva 1mm Allograft Dermis) is available and will be calculated. All breast reconstruction related costs billed by Washington University Physicians from the first surgery up until immediately before the second surgery will be included.

    Measured: Up to 15 months

  11. Amount of tissue expander fill

    -This is breast-level data since the left and right side may differ in bilateral reconstruction cases. The investigators already track tissue expander fills as part of the electronic medical record. The amount of tissue expander fill during surgery and device type are recorded in the operative record.

    Measured: At the time of surgery

  12. Immediate implant type as measured by volume (cc)

    Measured: At the time of surgery

  13. Immediate implant type as measured by manufacturer

    Measured: At the time of surgery

  14. Immediate implant type as measured by shape

    Measured: At the time of surgery

  15. Immediate implant type as measured by fill

    Measured: At the time of surgery

  16. Immediate implant type as measured by surface characteristics

    Measured: At the time of surgery

What is this clinical trial studying?

A Phase 2 study testing Alloderm RTU, Cortiva 1mm Allograft Dermis and Skin or nipple-sparing mastectomy in people with Breast Cancer, run by Washington University School of Medicine at 1 site in United States.

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

Who may be eligible to take part?

The sponsor lists 5 inclusion and 1 exclusion criteria. 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: finished, as of the sponsor's last update on 6 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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.

What does the primary outcome measure?

Incidence of premature tissue expander (TE) removal (time frame: Up to 15 months). It is what the study was designed to measure, not a finding.

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 May 2023; AzTrials last refreshed its copy on 27 Oct 2026.
