Study summary

Multi-center, three-arm, randomized, evaluator-blinded study of electrical muscle stimulation (EMS) and/or 1064 nm diode laser, pulsed electromagnetic field (PEMF) and vacuum assisted radio frequency (RF) using the Venus Bliss Max for fat reduction, body contouring and aesthetic improvement.

Read the detailed description

The study will enroll up to 60 male and female subjects, ≥ 18 years of age, requesting non-invasive electrical muscle stimulation (EMS) and/or lipolysis of the abdomen and flanks. Subjects will be randomized to one of three arms as per randomization scheme.

This study will have 3 Arms at a ratio of 2:1:1 (A:B:C):

Arm A: Full Treatment Arm (Laser + EMS + RF/PEMF) Arm B: EMS/RF Arm (EMS + RF/PEMF) Arm C: EMS Arm (EMS only)

Arm A: Three (3) diode laser treatments treatments at days 0, 28 and 56 (±2 days). Subjects will also receive bi-weekly electrical muscle stimulation and pulsed electromagnetic fields (PEMF)/vacuum assisted radio frequency (RF) treatments at days 0, 14, 28, 42 and 56 (±2 days).

Arm B: Subjects will receive bi-weekly electrical muscle stimulation and pulsed electromagnetic fields/vacuum assisted radio frequency treatments at days 0, 14, 28, 42 and 56 (±2 days).

Arm C: Subjects will receive weekly electrical muscle stimulation treatments at days 0, 7, 14, 21, 28 and 35 (±2 days).

Subjects in Arms A and B will be followed at 84 and 140 days (±7 days) after their last treatment. Subjects in Arm C will be followed at 63 and 119 days (±7 days) after their last treatment.

Terms in these criteria, in plain language(5)

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.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
