About this study

Official title: Prospective, Single-center, Single-arm Clinical Research Evaluating the Safety and Effectiveness of Linear Z for Non-invasive Body Contouring of the Abdomen and Flanks

This clinical study will evaluate the safety and effectiveness of LinearZ, a non-invasive focused ultrasound device, for body contouring of the lower abdomen and flanks.

Approximately 30 adults with localized fat in the abdomen and flanks will participate in the study. Each participant will receive one treatment with LinearZ to the lower abdomen and flanks and will be followed for approximately 90 days.

Read more

The main purpose of the study is to determine whether treatment with LinearZ reduces the circumference of the treated area 90 days after treatment. The study will also evaluate changes in body circumference at Day 30, changes in body contour and appearance, participant satisfaction, body weight, body mass index (BMI), and body composition. Standardized photographs and three-dimensional images will also be used to assess changes in the treated areas.

The safety and tolerability of the treatment will be evaluated throughout the study by monitoring adverse events and treatment-related pain or discomfort.

Read the detailed description

This is a prospective, single-center, single-arm, open-label clinical study designed to evaluate the safety and effectiveness of LinearZ for non-invasive body contouring of the lower abdomen and flanks.

Approximately 30 eligible adult participants with localized, visible, and measurable subcutaneous adiposity of the abdomen and flanks will be enrolled. All eligible participants will receive a single treatment with LinearZ to the lower abdomen and bilateral flanks. There is no randomization or comparator group in this study.

LinearZ is a focused ultrasound device designed to deliver ultrasound energy at specific depths within subcutaneous tissue for non-invasive body contouring. Treatment will be performed according to predefined study procedures and sponsor-approved treatment instructions. Treatment parameters, including the treatment area, cartridge type, treatment depth, energy level, and number of treatment lines or shots, will be documented.

Participants will undergo screening and baseline assessments before treatment and will return for follow-up assessments approximately 30 and 90 days after treatment.

The primary effectiveness assessment is the change from baseline in the circumference of the treated area at Day 90. Circumference measurements will be performed using standardized procedures at predefined anatomical landmarks.

Additional effectiveness assessments include change in circumference at Day 30, aesthetic improvement, participant satisfaction, changes in body weight and body mass index (BMI), and changes in body composition. Standardized clinical photography and three-dimensional imaging will also be used to document and evaluate changes in body contour. Independent blinded evaluators will review standardized images to help minimize assessment bias.

Safety and tolerability will be evaluated throughout the study by monitoring treatment-emergent adverse events, device-related adverse events, serious adverse events, and treatment-related pain or discomfort. Immediate post-treatment skin reactions and other local responses will also be assessed.

Each participant will participate in the study for approximately 90 days from the day of treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • High Intensity Focused UltrasoundDevice

    Participants will receive a single treatment with the LinearZ focused ultrasound device for non-invasive body contouring of the lower abdomen and bilateral flanks. The device delivers focused ultrasound energy at specific depths within the subcutaneous tissue. Treatment will be performed according to the sponsor-approved treatment manual, site-specific operating procedures, and study procedures. All participants will receive treatment to both the lower abdomen and flanks during the treatment session and will be followed for approximately 90 days after treatment.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in Circumference of the Target Area at Day 90

    The change in circumference of the treated target area from baseline to Day 90 will be assessed using standardized circumference measurements. The target area includes the lower abdomen and bilateral flanks. Circumference will be measured at a predefined and documented anatomical level using a standardized procedure, and the average of three consecutive measurements will be used for analysis.

    Measured: Baseline to day 90

Secondary outcomes (10)
  1. Change From Baseline in Circumference of the Target Area at Day 30

    Change in circumference of the treated target area from baseline to Day 30 will be assessed using standardized circumference measurements at predefined anatomical points encompassing the lower abdomen and bilateral flanks. The average of three consecutive measurements will be used for analysis.

    Measured: Baseline to Day 30

  2. Proportion of Participants Achieving ≥5 cm Reduction in Circumference at Day 90

    Percentage of participants who achieve a reduction of at least 5 cm in circumference of the treated target area compared with baseline.

    Measured: Baseline to Day 90

  3. Proportion of Participants Achieving ≥10 cm Reduction in Circumference at Day 90

    Percentage of participants who achieve a reduction of at least 10 cm in circumference of the treated target area compared with baseline.

    Measured: Baseline to day 90

  4. Global Aesthetic Improvement Scale (GAIS) Score

    Aesthetic improvement of the treated area will be assessed using the Global Aesthetic Improvement Scale (GAIS) at follow-up visits.

    Measured: Day 30 and Day 90

  5. Blinded Independent Photographic Evaluation of Aesthetic Improvement

    Independent blinded evaluators will assess aesthetic improvement using standardized photographs obtained at baseline and follow-up visits.

    Measured: Baseline, Day 30 and Day 90

  6. Participant Satisfaction With Treatment Outcome

    Participant satisfaction with the treatment outcome will be assessed using the study-specified satisfaction questionnaire.

    Measured: Day 30 and Day 90

  7. Change From Baseline in Body Weight

    Change in participant body weight from baseline will be assessed at follow-up visits.

    Measured: Baseline to Day 30 and Day 90

  8. Change From Baseline in Body Mass Index (BMI)

    Change in BMI from baseline will be assessed at follow-up visits. BMI is expressed in kg/m².

    Measured: Baseline to Day 30 and Day 90

  9. Change From Baseline in Fat Mass and Fat-Free Mass

    Change in fat mass and fat-free mass from baseline will be assessed using the InBody body composition measurement system.

    Measured: Baseline to Day 30 and Day 90

  10. Procedural Pain and Discomfort Score Using an 11-Point Numeric Rating Scale

    Procedural pain associated with radiofrequency treatment will be assessed using an 11-point Numeric Rating Scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater procedural pain.

    Measured: Immediately after each treatment.
