Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- Ages 21 to 65 years
- Women only
- Healthy volunteers accepted
- Adult, Older adult
Who may be able to join
- Patients must consent in writing to participate in the study by signing and dating an informed consent document indicating that the patient has been informed of all pertinent aspects of the study prior to completing any of the screening procedures.
- Female of any race, age 21-65.
- Patients must desire a small breast augmentation with a ½-1 cup size increase in their breast volume. (If they wish to have a larger breast size increase, then they must understand a secondary procedure may be required to achieve that size increase).
- Patients must have a normal physical exam with no breast masses, no nipple discharge, no fibrocystic disease, no axillary adenopathy and/or history of abnormal bleeding.
- Patients must not be pregnant or lactating when enrolled in the study and must agree to have a pregnancy test (urine or blood) prior to the surgical procedure. - The patient should also not be trying to get pregnant during the course of the study.
- Patients must have a stable weight and not be fluctuating in their weight (otherwise this will distort volumetric measurements of breast size post operatively, making it impossible to determine true augmentation volume from SVF-enriched AFG).

- Patients must also consent to be photographed before and after the procedure and at the end of the study.
- All patients in the level I (randomized) and level II (nonrandomized) part of the study must also consent to undergo ultrasound imaging of the breast prior to the procedure and after the procedure to evaluate and treat any oil-filled cysts that may arise due to the procedure.
- All patients in the level I (randomized) and level II (nonrandomized) part of the study must also consent to allow their results to be included in any scientific research, scientific publication, or presentations at scientific meetings.
- All patients in the level I and level II part of the study must also consent to allow their photos to be used for publication in scientific journals, internet website, and patient educational material such as brochures, before and after photos, and patient education videos.
- All patients in the study must also agree to have mammography done when indicated after the procedure.
- All patients in the study must agree to have a biopsy of any suspicious abnormality seen on mammography, ultrasound, or MRI during the study.
- Patients must not be anemic at the time of the procedure (Hg < 10). If they are anemic at the time of enrollment, they can still be included in the study if the anemia is corrected pre-operatively with iron supplementation. This must be continued during the study to avoid any adverse reporting that may not be related to the procedure (i.e. anemia not caused by SVF-enriched fat grafting)
- Patients must have no history of abnormal bleeding during surgery, bruising and no personal/family history of coagulopathy.
- Patients must be off aspirin and other NSAIDs for two weeks prior to the procedure and have a normal blood coagulation panel within two weeks of surgery: Pts > 150K, PT(INR) < 1.3, APTT <1.3×control.
- Patients must have normal renal function (demonstrated by a Creatinine ≤ 1.5 mg/dl,) and no urinary tract infection (less than 5 WBCs on UA and leukocyte esterase negative on U/A Dipstick). If a UTI is present, the patient may still enroll if this is treated pre-operatively
- If a multigenerational family history of breast cancer or ovarian cancer is present, a surgical or medical oncologist must evaluate the patient to obtain pre-operative clearance and to provide reassurance that they do not need BRCA testing.
- Patients with prior radiation to the chest wall (for Hodgkin's disease) may not be included in the study.
Who cannot join
- Patients with a positive pregnancy test
- Patients with an abnormal breast exam
- Patients with a bleeding disorder who are on anticoagulants

About this study
Grafting of autologous stromal cell trial is a prospective study comparing routine fat grafting versus stromal vascular fraction enriched fat grafting.
Read the detailed description
The purpose of this study is to objectively compare outcomes between autologous fat grafting breast augmentation and stromal vascular fraction enhanced autologous fat grafting for cosmetic breast augmentation in a carefully designed study.
Patients will be given the option of participating in one of two studies:
- A small, level I study will compare AFG to SVF-enriched AFG in the same patient. One breast will be treated with AFG alone (control) and the other breast with SVF-enriched AFG (experimental).
- A larger, level II study comparing AFG to SVF-enriched AFG in different patients. The patient will either receive AFG alone in both breasts or SVF-enhanced AFG in both breasts.
- Conditions
- Micromastia
- Being tested
- Adipose Derived Stem Cells, SVF Enriched Autologous Fat Grafting
- Keywords
- Autologous Fat Grafting, Breast Augmentation, Stromal Vascular Fraction, Adipose Derived Stem Cell

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Adipose Derived Stem Cells and SVF Enriched Autologous Fat Grafting in people with Micromastia, run by Tower Outpatient Surgical Center 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 18 inclusion and 25 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: status not confirmed, as of the sponsor's last update on 13 May 2015. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Cloe S Hakakian, BS (3106590705, cloe@aronowitzmd.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Comparing change from baseline to outcomes between autologous fat grafting alone and stromal vascular fraction enriched fat grafting for breast augmentation (time frame: 1 month, 3 months, 6 months, 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02116933, which also lists 9 linked publications.
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 13 May 2015.
