Clinical Trial Summary

Up to 260 subjects presenting with skin laxity on the face and neck will be randomized to one of two treatment groups. Subjects meeting all entrance criteria will receive study treatment, then complete two post treatment phone contacts and follow-up study visits at 90, 180 and 365 days post treatment. Study images will be obtained pre-treatment, immediately post-treatment, and at each follow-up visit for qualitative and quantitative assessments of efficacy.

Description:

This is a prospective, randomized, double blinded, multi-center, parallel arm, non-inferiority, pivotal clinical trial to demonstrate the efficacy of the Ultherapy treatment with prototype 2 simulines transducers (4-3.0 Smm and 4-4.5 Smm) at energy level (EL) 2 is non-inferior to treatment with standard transducers (7-3.0 mm and 4-4.5mm) at EL 2 for lifting the lower face and neck and to demonstrate the safety of treatment with prototype 2 simulines transducers is similar to treatment with standard transducers.

Changes from baseline in quantitative measures of neck and submental lift will be assessed at study follow-up visits. Global Aesthetic Improvement Scale scores, Merz Jawline Grading Scale scores, 3D volumetric changes from baseline to post treatment, patient satisfaction and patient-reported improvement will be obtained.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Number of Participants Who Achieved Greater Than or Equal to (>=) 20 mm^2 Reduction in Submental Area at Day 90	Participant response was defined as >=20 mm^2 reduction in 2D submental area from baseline. Submandibular and Submental quantitative measurements were calculated comparing participants using prototype 2 simulines versus standard transducers. The standard 2D photographic images were obtained. Utilizing the lateral profile view of pre-and 90-day post treatment photos of each participant, quantitative results were calculated by using 5 evenly spaced points on the neck. Area was calculated between each of the 5 points and then sum of the 5 calculations was the total area of the region of interest. The delta area between the pre-and post-treatment area of the chin and neck determined the amount of tissue lift in the area.	Day 90
Secondary	Number of Participants Who Achieved >=20 mm^2 Reduction in Submental Area at Day 180	Participant response was defined as >=20 mm^2 reduction in 2D submental area from baseline. Submandibular and Submental quantitative measurements were calculated comparing participants using prototype 2 simulines versus standard transducers. The standard 2D photographic images were obtained. Utilizing the lateral profile view of pre-and 180-day post treatment photos of each participant, quantitative results were calculated by using 5 evenly spaced points on the neck. Area was calculated between each of the 5 points and then sum of the 5 calculations was the total area of the region of interest. The delta area between the pre-and post-treatment area of the chin and neck determined the amount of tissue lift in the area.	Day 180
Secondary	Number of Participants Who Achieved >=20 mm^2 Reduction in Submental Area at Day 365	Participant response was defined as >=20 mm^2 reduction in 2D submental area from baseline. Submandibular and Submental quantitative measurements were calculated comparing participants using prototype 2 simulines versus standard transducers. The standard 2D photographic images were obtained. Utilizing the lateral profile view of pre-and 180-day post treatment photos of each participant, quantitative results were calculated by using 5 evenly spaced points on the neck. Area was calculated between each of the 5 points and then sum of the 5 calculations was the total area of the region of interest.

Secondary	Number of Participants Who Showed Improvement in Overall Lifting and Tightening of Skin at Day 90	Improvement was determined by qualitative assessment of photographs by a masked physician.	Day 90
Secondary	Number of Participants Who Showed Improvement in Overall Lifting and Tightening of Skin at Day 180	Improvement was determined by qualitative assessment of photographs by a masked physician.	Day 180

QuantifiCare 3D imaging was used to assess the volumetric changes. Four views (Face, UnderRight, UnderLeft, and Neck) were compared for each participant.	Day 365
Secondary	Number of Participants With Some Level of Improvement and Satisfaction on Day 90	Participants completed a patient satisfaction questionnaire (PSQ) at the 90-day visit. The PSQ has 5 improvement and satisfaction categories ranging from "worse" to "much improved" and "dissatisfied' to "very satisfied".	Day 90
Secondary	Mean Treatment Times	Mean treatment time was based on a comparison of average time to complete treatment using each transducer type. The time to complete the study treatment for each group was recorded on the system treatment logs as treatment start time (time treatment started on the Ulthera system) and stop time (time treatment ended on the Ulthera system).	Baseline
Secondary	Mean Pain Scores to Assess Participant's Treatment Related Comfort Level Based on Numeric Rating Scale (NRS)	Participant's treatment-related pain scores were obtained using a validated 11-point NRS with 0: no pain; 5: moderate pain; and 10: worst possible pain. Pain scores were obtained following each region treated (submandibular/submental and cheeks) and for each transducer used during treatment. Average pain score was calculated for each arm by adding all the scores of all participants in each arm to obtain the mean NRS score.	Baseline
