Immediate Postmastectomy Breast Reconstruction (Strattice Breast)

October 4, 2016 updated by: LifeCell

A Multicenter, Prospective, Open-Label Study to Assess the Clinical Outcomes of LTM Use in Two-Stage Breast Reconstruction Immediately Post Mastectomy

This prospective, multicenter, open-label study will assess the clinical outcomes of the LTM product in three planned analyses. The primary objective of this study is to prospectively assess the clinical outcomes associated with the use of LTM in two-stage (expander then permanent implant) immediate post-mastectomy breast reconstruction.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Sampling Method

Non-Probability Sample

Study Population

women undergoing two-stage immediate breast reconstruction following a skin sparing mastectomy will be recruited from up to ten (10) participating centers

Description

Inclusion Criteria:

  • A candidate for immediate, two-stage breast reconstruction using LTM following a skin sparing mastectomy
  • An ASA Physical Status Classification5 of 1 or 2 (see App I)
  • Estimated life expectancy > 1 year

Exclusion Criteria:

  • Clinically significant systemic disease
  • Received inductive chemo-therapy within 2 months prior to mastectomy or radiation therapy to the region at any time
  • Predicted excised breast mass of >750 gms
  • Co-morbid factors which predispose to postoperative infection, such as insulin dependent diabetes, smoking, chronic steroid use, malnourishment, or co-existent infection
  • Need for tissue flap in addition to expander
  • History of alcohol abuse, illicit drug use, significant mental illness, physical dependence to any opioid, or drug abuse or addiction
  • Enrollment or plans to enroll in another clinical trial during this study that would affect the patient's safety or results of this trial
  • Any of the conditions identified within the labeled contraindications, i.e. sensitivity to porcine derived products or polysorbate

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Histology Sample Evaluations Assessing Incorporation of StratticeTM Reconstructive Tissue Matrix
Time Frame: At the time of expander/implant exchange (Stage II),
Evaluation of 3 histology parameters, fibroblast infiltration, immune cell response & revascularization, expressed as frequency distributions. Samples evaluated for presence of fibroblasts (cellularity), neovascularization & immune cell response using 4 pt scale. Fibroblast Infiltration: 1=None,2=Few,sparse,3=Moderate,4=Dense. Revascularization:1=None,2=Few randomly dispersed capillaries,3=Moderate; mostly homogenous distribution of new vessels,4=Significant,uniformly distributed vessels; both capillaries and arterioles. Immune Cell response: 1= None,2=Few,normal healing response,3=Moderate,4=Significant;above expected presence for healing. 4 high power(HP)fields reviewed & if uniform in appearance/cellular distribution, 4 considered representative of sample as a whole. If non-uniform distribution observed, 3 HP fields of "sparse or light" distribution & 3 HP fields of dense distribution counted & results averaged. Tissue sample then assessed for overall acellularity & expressed as %.
At the time of expander/implant exchange (Stage II),

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Severity of Local Inflammation at and Around the Surgical Site
Time Frame: Postoperative Day 7, 14, 21, 30 days
The Inflammatory response was evaluated by each of the four cardinal signs: erythema, edema, pain and heat, using standard scales for the evaluation of each sign and inflammation as a whole was assessed using a model (AIR Score) which took into account the scores assigned to each of the four signs. A mean score is provided at each timepoint.The minimum total possible score is 4 (less inflamation) and the maximum total possible score is 8 (more inflammation).
Postoperative Day 7, 14, 21, 30 days

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
October 1, 2007

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
