Alopecia, Androgenetic | Device: Puregraft System Device: Celution System Procedure: Kerastem Therapy Procedure: Liposuction | Not Applicable |
The STYLE Trial is a prospective, randomized, multi-center device trial intended to evaluate the safety and efficacy of the Celution and Puregraft Systems in the processing and preparation of an autologous fat graft enriched with adipose-derived regenerative cells (ADRCs) in the treatment of early alopecia androgenetica. Patients may be included if they are undergoing an elective cosmetic liposuction. Following informed consent and screening evaluations, eligible subjects will undergo pre-operative testing. Subjects will then undergo a fat harvest using local anesthesia with or without conscious sedating. Subjects will be randomly assigned to receive a fat graft cell enriched with ADRCs (available in two different doses),a fat graft without cell enrichment using a visually-matched blood saline solution (fat alone control), or a saline injection (no-fat control) in a 2:2:2:1 ratio.
While undergoing liposuction, lipoaspirate will be processed in the Puregraft System to remove the lipoaspirate of impurities and in the Celution System to isolate and concentrate ADRCs. After the liposuction is completed), patients will have, under a ring block local anesthesia (see further description below), a subcutaneous scalp injection of either Puregraft purified autologous fat or saline (no-fat control) followed by a separate second injection, of either ADRCs (available in two different doses),a visually-matched blood saline solution (fat alone control), or saline (no-fat control) in a 2:2:2:1 ratio.
The STYLE Clinical Trial will have a sample size of 70 patients at up to eight (8) centers.
Study Type : | Interventional (Clinical Trial) |
Actual Enrollment : | 71 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | Subjects arm randomized prior to liposuction 2:2:2:1 ratio to one of 4 Arms. Low Dose ADR, High Dose ADRC, non enriched fat only, and no fat (control normal saline). |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | Randomization via manual treatment assignment by the unblinded Clinical Supply Manager prior to the start of liposuction. Subjects randomized into the study are assigned their study Arm corresponding to the next available number in the computer-generated randomization schedule. Dose preparation ios performed by designated unblinded qualified personnel and supplied to the blinded treating team. |

Arm | Intervention/treatment |
---|---|
Experimental: Fat + High Dose ADRC
Kerastem Therapy includes micro-liposuction followed by subcutaneous scalp injection of purified adipose prepared with the Puregraft System + 1,000,000 ADRC prepared with the Celution System per square centimeter of scalp.
|
Device: Puregraft System
The Puregraft System prepares purified adipose tissue for subcutaneous scalp injection. Device: Celution System The Celution System prepares adipose derived regenerative cells (ADRCs) for subcutaneous scalp injection. Procedure: Kerastem Therapy The Kerastem Therapy is the subcutaneous scalp injection of purified adipose prepared with the Puregraft System enriched with ADRCs prepared from the Celution System. Procedure: Liposuction Tissue collection involving the micro-harvest of subcutaneous adipose tissue. |
