Trial Information

AirXpanders Patient Activated Controlled Tissue Expander System for Breast Reconstruction

This is a pivotal, prospective, multi-center randomized, controlled, open-label clinical
study designed to compare the performance and safety of the AirXpander Tissue Expander
System to currently cleared saline tissue expanders. Subject who meet the inclusion and
agree to participate in the study will be enrolled and randomized to either the
investigational arm (AirXpander Tissue Expander) or the control arm (standard saline tissue
expander) using a 2:1 (AirXpander to saline) permuted block randomization stratified by
investigational center and procedure (unilateral or bilateral). If the subject is having a
bilateral procedure, the same type of expander will be implanted in each side. Subjects in
both arms will be followed in the same manner until the explantation of the tissue
expander(s) and exchange for permanent implant(s).

Inclusion Criteria:

1. Subject is a woman between the ages of 18-70.

2. Subject needs to have tissue expansion as part of her breast reconstruction.

3. Subject is able to provide written informed consent.

4. Subject is able and willing to comply with all of the study requirements.

5. Subject is able to understand and manage at home dosing regimen.

Exclusion Criteria:

1. Subjects skin is not suitable for tissue expansion.

2. Subject has remaining tumor cells following her mastectomy.

3. Subject has a current or prior infection at the intended expansion site.

4. Subjects skin has been damaged by previous radiation treatments and the use of non
radiated tissue from another part of her body will not be used.

4a. Subject had planned radiation therapy at the intended expansion site while the
expander is implanted.

5. Subject has a history of failed tissue expansion or breast implantation at the intended
expansion site.

6. Subject has any existing medical condition that the doctor thinks puts the subject at
an increased risk of complications (e.g., severe collagen vascular disease, poorly managed

7. Subject is taking any medications that the doctor thinks puts the subject at an
increased risk of complications (e.g., prednisone, Coumadin).

8. Subject is currently participating in a concurrent investigational drug or device

9. Subject is a current tobacco smoker. 10. Subject is overweight (BMI > 33). 11. Subject
is unwilling to comply with the air travel or altitude restriction of not > 3300 feet
(1000 meters) from baseline during the time the AeroForm tissue expander is implanted.

12. Subject has a currently implanted electronic device such as a pacemaker,
defibrillator, neurostimulator device, or drug infusion device.

13. Subject is pregnant or planning on becoming pregnant during the study period.

14. Subject has a history of psychological condition, drug or alcohol misuse which may
interfere with their ability to use the device safely.

Type of Study:


Study Design:

Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

Successful tissue expansion and exchange to a permanent breast implant unless precluded by a non-device related event

Outcome Description:

The primary endpoint will be assessed when the subject has completed tissue expansion and had an exchange to permanent breast implants. Subjects not completing permanent breast implant procedure will be considered failures if the procedure could not be completed due to a device related event.

Outcome Time Frame:

6 months
