Study summary

This study will evaluate the clinical safety and the performance of the BTL-899 device during the treatment of upper arms.

Read the detailed description

The aim of the study is to confirm the efficacy and the safety of the treatment. The efficacy (reduction of excess adipose tissue) will be assessed via correct identification of pre-treatment and 3-months follow-up images by at least two out of three independent blinded evaluators. The fat reduction will be also measured by means of ultrasound. Comfort and satisfaction will be assessed via standard questionnaires.

Safety measures will include documentation of adverse events (AE) during and after the procedures.

What researchers measure

Primary outcomes

  1. Statistically significant reduction of fat thickness in the upper arms evaluated by photographs

    To gather clinical evidence that the BTL-899 device is able to induce non-invasive lipolysis when used on upper arms. The primary efficacy outcome measure is a minimum 75% of the subjects' pre-treatment and 3-months follow-up images to be correctly identified by at least two of three independent blinded evaluators.

    Time frame: 5 months

Secondary outcomes

  1. Evaluation of the Therapy's Safety Measured Via Therapy Comfort Questionnaire

    Assessment the safety of the BTL-899 device when used for non-invasive lipolysis of the upper arms via questionnaires filled in by the participants following each therapy session. 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. The outcome will further be measured through the occurrence of adverse events or lack thereof.

    Time frame: 7 months

  2. Evaluation of the participants' satisfaction with the therapy evaluated via standard questionnaires

    Evaluation of the participants' satisfaction with the therapy and the results. ● Minimum 80% of treated subjects to report satisfaction (level satisfied and higher) with the therapy.

    Time frame: 5 months
