Study summary

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.

Read the detailed description

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.

    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
    10. Conditions affecting healing rate (i.e. diabetes mellitus I or II, vascular condition, etc.)
    11. neuromuscular disorders
  10. Subjects who have used, within 30 days, any medication that can cause dermal hypersensitivity or affect skin characteristics over the treated area (i.e. topically applied Retinoids, Hydroquinone, Chemical peel of any strength: glycolic acid, lactic acid, salicylic acid)
  11. Subjects who have used, systemic treatment which may induce dyspigmentation, such as amiodarone, clofazinmine, minocycline or chloroquine.
  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.

Study arms

  • Experimental
    Tixel 2

    Tixel 2 Treatment, 4 treatment sessions, followed by 2 Follow up sessions, 1and 3 months after last treatment visit. Subject would be questioned about pain level, subjective dountime assessment and subjective response assessment. Images would be taken at baseline and in Follow-Up visits

    Device: Tixel 2

Interventions

  • DeviceTixel 2

    Thermo-mechanical technology for fractional treatment of human skin. Dermal heating and coagulative effect that occur during the treatment session provide dermal remodeling and collagen restructuring that promote wrinkles appearance improvement.

What researchers measure

Primary outcomes

  1. Percentage of Participants With Safety Adverse Events

    Evaluation of related adverse events up to the 3-month after a treatment visit.

    Time frame: 6 months

  2. The Mean Improvement and Treatment Effectiveness by Blinded Assessors Using Using the Fitzpatrick Wrinkle Classification Scale (FWCS) Evaluation

    Comparison of the proportion of subjects with a ≥ 1-score improvement on the Fitzpatrick Wrinkle Classification Scale (FWCS) at the 3-month visit compared to baseline as determined by at least 2 out of 3 blinded Independent Photographic Reviewers. The FWCS is a clinically validated assessment tool used to assess skin wrinkle severity and elastosis on a scale from 1 through 9, where the lower score is considered better.

    Time frame: baseline and at 3 months

Secondary outcomes

  1. The Mean Evaluation of Improvement Assessed by the Handling Physician by Using GAIS Scale - Global Aesthetic Improvement Scale Assessment

    Assessment of improvement using Global Aesthetic Improvement Scale Assessment at each visit compared to baseline by the handling physician. Rating: 1) expectational improvement; 2) very improved patient; 3) Improved patient; 4) Unaltered patient; 5) Worsened patient

    Time frame: Baseline and 3 months visits

  2. The Mean Score Evaluation of the Pain and Discomfort for Each Treatment

    Evaluation of the pain and discomfort of the treatment as reported by the subject on a visual analog scale (VAS). Scoring will consist of making a mark on a 10-points scale. Each line will be awarded a score of 0 - 10 according to the level of pain when 0 is no pain and 10 is the maximum pain possible.

    Time frame: Up to 6 months

  3. Satisfaction Questionnaire

    Subject Experience (Satisfaction) questionnaire - Subjects assessed their satisfaction at the follow up visits. The following parameters were assessed: results of treatment, treatment experience and expectations (indicating whether the treatment has fulfilled the subject's expectations). For each parameter, the assessment was based on a 5-point scale: 1 = "Poor - Poor or not satisfied at all", 2 ="Fair - satisfied to some extent", 3 = "Moderately - Satisfied", 4 = "Good - Satisfied", 5 = "Excellent - Very Satisfied".

    Time frame: up to 6 months
