The primary objective of this study is to evaluate the safety and feasibility 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.

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.

4. Subject must have no previous hair transplant, cell treatment, micro needling, or any other treatment in the last 6 months in the scalp.
5. Subject is currently suffering from an active autoimmune disease such as serum lupus erythematosus, or alopecia areata. Subject is currently suffering from dermatologic condition in the treatment area or has a significant scar in the hair treatment area that, in the opinion of the investigator, will make hair growth difficult (such as systemic burns, etc.).

11. Clinically significant medical or psychiatric illness currently or within 30 days of study screening as determined by the investigator
12. Prior surgery in the treatment area
13. Any disease or condition (medical or surgical) that, in the opinion of the investigator, might compromise dermatologic, hematologic, cardiovascular, pulmonary, renal, gastrointestinal, hepatic, or central nervous system function; or any condition that would place the subject at increased risk
14. Pregnant or lactating women or women trying to become pregnant
15. Known allergic reaction to components of study treatment and/or study injection procedure
16. Subject has any disorder that may prevent compliance to study procedures and visits
17. Subject who is part of the study staff, a family member or friend
18. Diabetes or thyroid disorder
19. Subject who has a sensitive, irritated, or abraded scalp area.
20. Women who have an alternate diagnosis that is associated with hair loss.
21. Body Mass Index < 18kg/m2
22. Clinically significant abnormal findings on laboratory screening panels, including hemoglobin ≤ 10 g/dL.
23. Hepatic dysfunction, as defined as aspartate aminotransferase (AST), alanine aminotransferase (ALT), or bilirubin levels > 1.5 times the upper limit of normal range (x ULN) prior to randomization.
24. Chronic renal insufficiency as defined as a serum creatinine > 1.2 mg/dL for women and > 1.5 mg/dL for men.

All subjects were included in the analysis population.

From Enrollment through 52 Weeks

Events were reported by Investigators, which was supplemented by information from study subjects to Investigators. Attribution was performed by study Medical Director. No adverse Events were attributed to the experimental procedure / product.

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.
