Safety and Efficacy of Cryolipolysis Clinical Protocols

Phase 4

Completed

• Conditions: Fat Loss
• Interventions: Device: Polarys Cryolipolysis

• Registration Number: NCT06541899
• Lead Sponsor: Indústria Brasileira Equipamentos Médicos - IBRAMED

Brief Summary

A single-arm, multicenter interventional clinical study will be conducted. The objective is to evaluate the safety and efficacy of the cryolipolysis technique. Approximately 372 participants will be included. After analyzing the items listed above, the participants in each study will be divided into 3 distinct intervention groups. The individuals included in the study will undergo anamnesis and data collection.

Detailed Description

The participants in each study will be divided into 3 distinct intervention groups (Grupo 1: aplicador 360° M - Região abdominal; Grupo 2: aplicador 360° G - Região abdominal; Grupo 3: aplicador de placas - Região dos flancos). After analyzing the inclusion and exclusion criteria of this study, the individuals included in the study will undergo anamnesis and data collection after the procedure and 6 weeks and 20 weeks after: photographic capture, bioimpedance, perimetry, adipometry and ultrasound imaging of the treated area, in addition to a pain and patient satisfaction questionnaire.

Inclusion Criteria

• The participant (healthy volunteer) who has read and signed the informed consent form for the study.
• Male or female ≥ 22 years and ≤ 65 years of age.
• Subjects with a body mass index (BMI) of 30 or less and who have a greater volume of adipose tissue in the abdomen (except precordial region) and flanks.
• Subject has not changed in weight more than 5% of body weight in the previous month.
• Subject agrees to maintain his/her weight (i.e., within 5%) by not making major changes in his/her diet or exercise routine during the study.
• Subject agrees to have photographs taken of the treatment area(s) during the scheduled periods.

Exclusion Criteria

• Diabetes mellitus or need to administer or known history of subcutaneous injections in the area of intended treatment (e.g. heparin, insulin) in the last month;
• Metabolic and/or liver diseases that compromise vitamin metabolism;
• Being pregnant or planning to become pregnant during the study period (within the next 8 months);
• Being breast-feeding or having breast-fed in the last 6 months;
• Having a known sensitivity to cold, such as cold urticaria, Raynaud's disease, chilblains (pernio) or any known condition with a response to cold exposure that limits blood flow to the skin;
• Irritated skin or presence of dermatitis;
• Keloids or propensity for keloids in the area to be treated;
• Having a history of hernia in the area(s) to be treated.
• Any dermatological conditions, such as moderate to excessive skin laxity, or scarring at the location of the treatment sites that may interfere with treatment or evaluation (stretch marks are not an exclusion);
• Have a history of a bleeding disorder or are taking any medications that, in the opinion of the investigator, may increase the risk of bruising;
• Recent surgery at the treatment site;
• Regular use of anti-inflammatory medications;
• Are taking or have taken any pills or dietary supplements within the past month.
• Invasive fat reduction procedure (e.g., liposuction, mesotherapy) in the intended treatment area;
• Implanted electronic devices (e.g., pacemaker);
• Are currently enrolled in a clinical trial of any unapproved investigational drug or device.
• Any other condition or laboratory value that could, in the professional opinion of the investigator, potentially affect the subject's response or the integrity of the data or pose an unacceptable risk to the subject.

Arm && Interventions

Group	Intervention	Description
Group 1 - 360° M applicator, abdominal	Polarys Cryolipolysis	Group 1: 360° M applicator - Abdominal region
Group 2 - 360° G applicator, abdominal	Polarys Cryolipolysis	Group 2: 360° G applicator - Abdominal region
Group 3 - flanks	Polarys Cryolipolysis	Group 3: Plate applicator - Flank region

Primary Outcome Measures

Name	Time	Method
% reduction in fat layer assessed by ultrasound, adipometer and photography	Immediately after the procedure and 6 and 20 weeks after	Adipometer: to measure the thickest point within the treatment area. For the evaluation in the abdominal region, reference points located 5 cm to the side of the umbilical scar, both on the right and left sides, will be recorded. For the evaluation in the flank region, the measurement will be standardized using the axillary midline, being performed exactly in the central fold of each flank; Ultrasound: subcutaneous tissue between the anatomical planes. The probe will be positioned at the points previously marked in the treatment area, following the same measurement performed for adipometry; Photography: at fixed angles and postures with standardized disposable underwear. Three-dimensional images will be taken of the subjects in sagittal (left and right sides) and coronal (front and back sides) views at baseline and at the stipulated follow-up periods. The abdominal region will be exposed and the subject will be instructed to remain still while the camera captures an image.
Ocurrence of adverse events after de procedure assessed by clinical evaluation	After de procedure and 6 and 20 weeks after	Adverse events such as erythema, pain, edema or any other event that occurs in correlation with the treatment, through monitoring in the reassessments stipulated in the study and also in a questionnaire answered by the patient

Secondary Outcome Measures

Name	Time	Method
Patient"s satisfaction assessed by GAIS scale	6 weeks and 20 weeks after the cryolipolysis procedure	Patient satisfaction level will be categorized using the 5-point Global Aesthetic Improvement Scale (GAIS). It is divided into 5: "excellent", 4: "greatly improved", 3: "improved", 2: "no change" and 1: "worsened".
