Clinical Study Evaluating the Safety and Effectiveness of The Tixel Fractional System in The Treatment of Periorbital Wrinkles

A Prospective, Multicenter, Single-Arm Clinical Study Evaluating the Safety and Effectiveness of The Tixel Fractional System in The Treatment of Periorbital Wrinkles

A Prospective, Multicenter, Single-Arm Clinical Study of 51 study subjects who are seeking a procedure to reduce the appearance of the peri-orbital wrinkles. Up to 5 investigational centers in Israel and the United States will participate in the recruitment. Each study subject will receive four (4) treatments with Tixel in a monthly interval. Follow-up will occur 1 month and 3 months following last treatment.

A Prospective, Multicenter, Single-Arm Clinical Study of 51 subjects who are seeking a procedure to reduce the appearance of the periorbital wrinkles, and meet study eligibility criteria, and have provided informed consent will be enrolled in the study. Up to 5 investigational centers in Israel and the United States will participate in the recruitment. Each study subject will receive 4 treatments with Tixel in a monthly interval. Follow-up will occur at 1 month and 3 months following the last treatment.

The clinic visits will be as follow:

1. Baseline (1st tx)
2. Phone-call visit (3 days after the first treatment)
3. 4wk (2nd tx)
4. 8wk (3rd tx)
5. 12wk (4th tx)
6. 4 weeks after the last treatment (1st FU)
7. 12 weeks after the last treatment (2nd FU= 3 months FU, primary endpoint and study completion visit) Primary Efficacy Endpoint is the comparison of the proportion of subjects with a ≥ 1-score improvement on the FWCS at the 3-month visit compared to baseline as determined by at least 2 out of 3 blinded Independent Photographic Reviewers.

Primary Safety Endpoint is the evaluation of related adverse events up to the 3-month visit after treatment.

Inclusion Criteria:

3. The subject is able to provide written informed consent and perform the study's activities according to HIPAA guidelines and/or Israeli law, depending on each specific study site.
4. Fitzpatrick wrinkle score of 3-7 in the peri-orbital areas per the treating investigator and clinically noticeable wrinkles in the treating area.
5. Stable body weight during the study period.
6. Skin Type I - V as per Fitzpatrick Skin Scale

6. Subjects who have had the following treatments:

   1. a cosmetic procedure to improve peri-orbital rhytides (i.e. periorbital or eyelid/eyebrow surgery, brow lift, CO2/Erbium/similar laser/fractional resurfacing, radiofrequency treatment) within 12 months
   2. prior facial treatments with laser, surgical, chemical or light-based facial treatments within the previous 12 months, over the periorbital area including botulinum toxin injections, microdermabrasion or prescription level glycolic acid treatments.
   3. Injectable filler in cheeks (mid face) temples and in the upper face area to be treated within 12 months of investigation.

7. Any subject who have visible scars or other visible changes over the treated areas that may affect evaluation of response and/or quality of photography.

8. Subjects with any type of active cut, wound, inflammation, lesion (benign, premalignant or malignant) or active bacterial, viral, fungal, or herpetic infection on the skin on the designated treatment sites or in close proximity to it.

9. Existing or history of the following (when discussing skin conditions, refers only to the periorbital sites):

   3. Immunosuppression or autoimmune disease
   4. Erythema with or without blistering
   5. History of post inflammatory hyperpigmentation.
   6. Active Acne Vulgaris, HSV-1, or any existing skin condition/disease that in the investigator's opinion would interfere with the evaluation of the safety of the study treatment and evaluation.
   7. Any skin pathology which can induce bullous lesions, urticaria, or demonstrate a Koebner phenomenon (psoriasis, lichen planus, etc.).
   8. Any disease that inhibits pain sensation
   9. History of keloid formation, or hypertrophic scarring

12. Subjects currently taking or have taken an oral retinoid in the past six months; Subjects currently taking long-term oral steroid treatment.

13. Concurrent therapy that, in the principal investigator's opinion, would interfere with the evaluation of the safety or efficacy of the study treatment.

14. Subjects who anticipate the need for major surgery or overnight hospitalization during the study that can affect the study schedule or treatment evaluation.

15. Enrollment in any active study involving the use of investigational devices or drugs.

16. Any other cause per the principal investigator's discretion.
