This study is designed to allow existing investigators continued access to the AeroForm Tissue Expander to treat patients while AirXpanders completes a marketing application and during the review process by FDA.

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.

Detailed Description

This is a prospective, multi-center, single arm, open-label, continued access clinical study. Subjects who meet the inclusion criteria and agree to participate in the study will be enrolled and implanted with the investigational AeroForm Tissue Expander. If the subject is having a bilateral procedure, the AeroForm expander will be implanted in each side. Subjects will be followed until the first post-operative visit after explant of the tissue expander(s) and exchange for permanent implant(s).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

14 years to 66 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • Subject is female between the ages of 18-70
  • Subject requires tissue expansion as part of breast reconstruction
  • Subject is able to provide written informed consent
  • Subject is able and willing to comply with all of the study requirements
  • Subject has the physical, perceptual and cognitive capacity to understand and manage the at home dosing regimen

Exclusion Criteria:

  • Subject's tissue integrity is unsuitable for tissue expansion
  • Subject has residual gross malignancy at the intended expansion site
  • Subject has current or prior infection at the intended expansion site
  • Subject has a history of failed tissue expansion or breast reconstruction
  • Subject has any co-morbid condition determined by the Investigator to place the subject at an increased risk of complications (e.g., severe collagen vascular disease, poorly managed diabetes)
  • Subject is taking any concomitant medications determined by the Investigator to place the subject at an increased risk of complications (e.g., Prednisone, Coumadin).

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: AeroForm Tissue Expander
AeroForm Tissue Expansion inflation with carbon dioxide by remote control
Device: AeroForm Tissue Expander
The AeroForm Tissue Expander is a breast tissue expander implanted following mastectomy and activated by remote control to release small doses of carbon dioxide from an internal reservoir to fill and inflate the expander.

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
Number of Breasts With Successful Tissue Expansion With Exchange to a Permanent Breast Implant Unless Exchange is Precluded by a Non-device Related Event
Time Frame: 6 months
The primary endpoint is analyzed per breast. Breasts in which the expander is removed and/or replaced due to a device related adverse event or a device malfunction are counted as failures.
6 months

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
Number of Breast With Successful Tissue Expansion With Exchange to Permanent Implant Including All Breasts in the Per Protocol Cohort.
Time Frame: 6 months
Secondary analysis is repeated including all breasts in the PP cohort (including non-device related failures). The Treatment Success Rate by breast, based on the Per Protocol cohort, including all cause failures, is 95.2% (80/84). One subject (2 breasts) are not included in the analyses due to not completing the second stage surgery and withdrawal of consent.

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.
