Study summary

The purpose of this single site clinical study is to evaluate the safety and effectiveness of the Soliton Rapid Acoustic Pulse (RAP) device for the improvement of cellulite comparing two different RAP treatment doses.

Read the detailed description

This is a non-significant risk, single-center, prospective trial for safety, and efficacy using Soliton's RAP device for the improvement in the appearance of cellulite performed at 1 (one) clinical research site in the United States.

Approximately 15 healthy female participants between the age of 18-55 inclusive will be enrolled in this study.

Participants who sign the informed consent form and meet all the eligible criteria will be enrolled in the study. Each participant will undergo acoustic rapid pulse (RAP) treatments on each of the participants buttocks and legs. The participant's right buttock and leg will receive 100 Hz doses, and the participants left buttock and leg will receive 50 Hz doses.

Total study duration is anticipated to be at or less than 55 weeks from the first participant visit to the last participant observation visit. A total of 3 visits, plus two optional visits are planned for this study as listed below:

  • Visit 1: Baseline/Screening (-30 Days to Day 0)
  • Visit 2: Treatment (Day 0)
  • Visit 3: 12-week Follow-Up Visit (+/- 14 Days)
  • Visit 4: 26-week Follow-Up Visit (+/- 14 Days) (Optional)
  • Visit 5: 52 Week Follow-Up Visit (+/- 14 Days) (Optional)

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Assessing safety

    The primary safety short-term endpoint to be met if all treated participants were free from unexpected adverse events (UAEs) or serious adverse events (SAEs) attributable to the RAP treatment immediately post-treatment

    Time frame: Immediately post treatment

  2. Assessing safety

    The primary safety short-term endpoint to be met if all treated participants were free from unexpected adverse events (UAEs) or serious adverse events (SAEs) attributable to the RAP treatment at the short-term (12-week) visit.

    Time frame: 12 weeks post treatment

  3. Assessing Efficacy

    The primary effectiveness objective was to demonstrate improvement in the appearance of cellulite from the 100 Hz treatment is comparable to the 50 Hz treatment. Efficacy determined by the results of a blinded independent physician assessment (IPA) panel correctly identifying the 12-week post-treatment photographs from randomly placed side-by-side comparison of before and after photographs for both treatments. The primary effectiveness endpoint will be met if the rate of correctly identified before and after photos for 100 Hz treatment is not significantly lower than the 50 Hz treatment assessment.

    Time frame: At 12 week follow up visit

Secondary outcomes

  1. Assessing Participant Satisfaction

    Improvement in cellulite as measured by the percentage of participants who agree or strongly agree that the final photograph of the treatment area as compared to the baseline photograph, appears improved.

    Time frame: At the 12 week follow up visit
