Non-invasive Lipolysis and Improvement of Muscle Tone in Inner Thighs

Effect of BTL-899 Device for Non-invasive Lipolysis and Improvement of Muscle Tone in Inner Thighs

This study will evaluate the clinical efficacy and safety of the BTL-899 device for changes in subcutaneous fat tissue and muscle tissue of inner thighs. The study is a prospective multi-center open-label single-arm study. The subjects will be enrolled and assigned into a single study group. Subjects will be required to complete four (4) treatment visits and two follow-up visits. All of the study subjects will receive the treatment with the subject device

Detailed Description

This study will evaluate the clinical efficacy and safety of the BTL-899 device for changes in subcutaneous fat tissue and muscle tissue of inner thighs. The study is a prospective multi-center open-label single-arm study. The subjects will be enrolled and assigned into a single study group. Subjects will be required to complete four (4) treatment visits and two follow-up visits. All of the study subjects will receive the treatment with the subject device.

At the baseline visit, MRI imaging will be performed; the subject's weight and thigh circumference will be recorded. Photos of the treated area will be taken.

The treatment administration phase will consist of four (4) treatments, delivered 5-10 days apart. The applicator of BTL-899 will be applied over the treatment area. The device will induce visible muscle contractions along with heating of the subcutaneous fat. Each therapy session will last 30 minutes.

At the last therapy visit, the subject's weight and thigh circumference will be recorded, and photos of the treated area will be taken. In addition, subjects will receive a Subject Satisfaction Questionnaire to fill in.

Safety measures will include documentation of adverse events (AE), including the subject's experience of pain or discomfort after each procedure. Following each treatment administration and at all of the follow-up visits, subjects will be checked for immediate post-procedure adverse event assessment.

During the post-procedure visits (at 1-month and 3-month follow-up visits), the subjects will undergo a MRI imaging. Also, the subject's satisfaction will be noted, and weight with thigh circumference will be recorded. Photographs of the treated area will be taken. In addition, subjects will receive a Lifestyle Change Questionnaire to fill in.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Experimental; Subjects will be required to complete four (4) treatment visits and two follow-up visits.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The evaluation of structural changes of subcutaneous tissues of the inner thighs	The evaluation of structural changes of subcutaneous tissues between pre-treatment and post-treatment based on MRI imaging through measurements of the thickness of subcutaneous tissues.	4 months
The evaluation of structural changes of subcutaneous tissues of the inner thighs	The evaluation of structural changes of subcutaneous tissues between pre-treatment and post-treatment based on MRI imaging through evaluation of tissue composition and morphology.	4 months
The evaluation of change in adipose layer thickness	The evaluation of change in adipose layer thickness between pre-treatment and post-treatment based on thigh circumference measurements.	4 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Evaluation of the Therapy's Safety Measured Via Therapy Comfort Questionnaire	The outcome will further be measured through the occurrence of adverse events or lack thereof. On Numerical Analog Scale (0-10), where 0 represents 'no pain' and 10 represents 'worst possible pain' select the level of pain experienced during the treatment.	4 months
Patient's satisfaction with study treatment measured via questionnaires	To determine the patient's satisfaction with study treatment for non-invasive lipolysis and improvement of muscle tone in inner thighs. The 5-point Likert scale Satisfaction questionnaire will be used to evaluate the participant's satisfaction with the therapy outcome. Subject satisfaction will be assessed after the last therapy visit and during the follow-up visits with 4-therapy related questions with answer "Strongly agree" will be the best possible answer and "Strongly disagree" the worst.	4 months
