详细描述
In accordance with ANVISA's definition on RDC 07 of 2015, personal hygiene products, cosmetics, and perfume are preparations composed of natural or synthetic substances, for external use on the various parts of the body such as skin, hair, nails, lips, external genital, teeth and mucous membranes of the oral cavity, with the exclusive or main purpose of cleaning and perfuming them, changing their appearance, correcting body odors, protecting and/or keeping them in good condition. It is of great importance that companies conduct clinical studies of their products so that consumers have maximum safety with the lowest risk of use. After confirming the evidence of safety of use by humans, the manufacturing company must submit the results obtained to ANVISA (whether the company intends to sell it in Brazil), as well as establishing label warnings and consumer service guidelines based on the information obtained. According to Helsinki Declaration and Brazilian legislation, any research involving human beings must comply with ethical premises. The purpose of them is to protect individuals' integrity, dignity, well-being, rights, and confidentiality. Therefore, studies involving personal care products, cosmetics and perfumes in safety investigation phase (i.e. investigational products) must follow the recommendations of Good Clinical Practices (GCP).
STATISTICAL ANALYSIS PLAN For each study assessment area (face, upper chest, and back), four statistical analysis will be conducted: one global analysis and one analysis per phototype cluster (I-II, III-IV, and V-VI). A total of 12 statistical analysis will be performed.
Parameters to be Analyzed:
- Number of papules;
- Number of pustules;
- Number of nodules;
- Number of blackheads;
- Number of microcysts;
- Number of excoriated lesions without inflammation;
- Number of red acne residual marks;
- Number of brown acne residual marks;
- Number of inflammatory lesions (papules + pustules + nodules). Calculated parameter
- Number of retentional lesions (blackhead + microcysts). Calculated parameter
- Number of acne residual marks (red acne residual marks + brown acne residual marks). Calculated parameter
- Number of other lesions (excoriated lesions without inflammation + residual marks).

结局指标
主要结局
Acne lesion and acne residual brown and red marks count
时间窗: Day 0, Day 28 and Day 42
The acne count will be performed based on the "LesionsCount Guidelines v 0.1" provided by the sponsor and acquired images will confirm the lesion location and accountability for all three areas. To assess the IP efficacy, at D0, D28 and D42, the dermatologist will perform an acne lesion and residual marks count by type as follows: inflammatory lesions (nodules, pustules and papules, including recently excoriated papules), non-inflammatory/retentional lesions (open comedones/blackheads, closed comedones/microcysts) and other lesions (excoriated lesions without inflammation and red acne residual marks and brown acne residual marks), for each assessment area (face, upper chest and back).
次要结局

- Illustrative photographies of tested areas(Day 0, Day 28 and Day 42)
- Tolerance(Day 0, Day 28 and Day 42)
