Not Applicable

Terminated

• Conditions: Wrinkle
• Interventions: Device: Tixel; Device: Laser

• Registration Number: NCT03454672
• Lead Sponsor: Novoxel Ltd.

Brief Summary

This study is designed to explore the safety and the effectiveness of the Tixel device. This device performs fractional treatment of the skin by applying thermal (heat) energy to the skin. The study shall compare the safety and the effectiveness of the Tixel with the safety and the effectiveness of a laser device which is currently cleared for marketing in the US.

4. Subjects who have had the following treatments:

   1. a prior cosmetic procedure to improve facial rhytides (i.e., rhytidectomy, 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 6 months, such as for botulinum toxin injections, retinoid, microdermabrasion or prescription level glycolic acid treatments
   3. Injectable filler in area to be treated within 9 months of investigation.
   4. permanent facial implant

5. Any subject who have visible scars that may affect evaluation of response and/or quality of photography.

6. 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.

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

   1. skin malignancy, or any diagnosis of suspected malignancy
   2. Collagen or vascular or bleeding disease
   3. Immunosuppression or autoimmune disease
   4. Erythema with or without blistering
   5. History of post inflammatory hyperpigmentation.
   6. Active Acne Vulgaris, Herpes Simplex Virus (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.
   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

8. Subjects who have used, within 30 days, any medication that can cause dermal hypersensitivity or affect skin characteristics (i.e. topically applied Retinoids, Hydroquinone, Chemical peel of any strength: glycolic acid, lactic acid, salicylic acid)

9. Subjects who have used, systemic treatment which may induce dyspigmentation, such as amiodarone, clofazinmine, minocycline or chloroquine.

10. Subjects currently taking or have taken an oral retinoid in the past six months (risk of scarring with therapy); Subjects currently taking long-term oral steroid treatment (causing fragility of the skin, risk of hematoma and bullae formation); Subjects taking Isotretinoin (Accutane or Roaccutan) within past 12 months.

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

12. Subjects who anticipate the need for surgery or overnight hospitalization during the study.

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

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

Group	Intervention	Description
Tixel	Tixel	Tixel Treatment.
Laser	Laser	Laser Treatment.

Primary Outcome Measures

Name	Time	Method
Mean Change by Blinded Assessor Evaluation by Fitzpatrick Classification of Facial Wrinkling (FWCS) Scale	baseline, 42 Weeks	The FWCS shall be assessed and quantified by 3 blinded assessors comparing baseline visit to +42 weeks visit.

Secondary Outcome Measures

Name	Time	Method
Mean Change of Subject Experience as Measured by Subject's Subjective Satisfaction Score	Treatment 1 (Baseline), Treatment 4 (Week 12), Treatment 5 (Week 16), Follow-up Visit 1 (Week 20), Follow-up Visit 3 (Week 42)	Subjective satisfaction is scored on a scale from 1-5, from excellent (5-very satisfied) to poor (1-poor or not satisfied at all). compring results from baseline to 42 weeks.; total minimum total score - 3, total maximum score - 15
Pain Level as Measured by the Visual Analog Scale (VAS) Scale	treatment 1 - treatment 5	Secondary Safety- VAS is scored on a scale from 0-10, with 0 indicating no pain and 10 indicating worst pain. This will be assessed at each treatment over 8 weeks to 16 weeks (Depending on number of Treatments given).
Mean Score Performance as Measured by the Fitzpatrick Classification of Facial Wrinkling (FWCS)	baseline, 42 Weeks	The FWCS shall be assessed and quantified by the handling physician at study visits 1-8. The FWCS is classified as I-III, where I indicated mild/fine wrinkles and III indicates moderate wrinkles. (baseline to 42 weeks)
Mean Score of Performance as Measured by 5-point Wrinkle Assessment Scale (WAS)	42 Weeks	The 5-point WAS is scored on a scale from 0-4, with 0 indicating no visible wrinkles and 4 indicating very deep wrinkles. This will be assessed at study visits 1-8. (baseline to 42 weeks)
Number of Days Reported by Subject Using Subjective Subject Downtime Assessment	visit 1 - visit 5	This assessment determines the number of days required for the subject to return to normal, daily activities. This will be assessed at each treatment visit : visit 1 - visit 5.; The downtime assessment was evaluated after each Tixel treatment visit. The therapist asked the subject in the next visit regarding the 3 parameters that relate to the total downtime assessment.; The parameters were: 1. Return to work (Days); 2. Return to social activities (Days); 3. Scabs (Days); The results for subjective Downtime assessments were grouped by two categories: * More than 2 days vs. less or equal to 2 days for Return to work, Return to social activities, Redness, Edema, and Scabs.; * More than 4 hours vs. less or equal to 4 hours for sensation of heat.
Number on End-User Experience Scale	After performing 5 treatments with each device. After performing between 20 or 30 treatments with each device. After completing all the required treatments in the investigator's study site with both devices.	The scores were converted to the same scale (a minimal score of 10 and a maximal score of 100 ) for both treatments, where a score of 10 is considered the wors outcome, and a score of 100 is considered the better outcome. For ResurFX, the maximal score is 45 therefore, the transformed score= total score \*45 /100; for Tixel the maximal score is 50 therefore the transformed score =\*50/100.
Mean Improvement Performance as Measured by Improvement Global Assessment	visit 2, 3, 4, follow up 1, 2, 3	Improvement Global Assessment is scored on a scale from 1-4, with 1 indicating a poor response and 4 indicating an excellent response. This will be assessed at study visits 2-8. (from week 4- week 42)
