简要总结
The clinical trial has a randomized, double-blind, placebo-controlled design, in which the aim is to evaluate the effect of a probiotic mix, with a 12-week treatment, on the evolution of rosacea.
This 12 weeks of treatment are structured into three visits: Visit 1 (initial; week 0), Visit 2 (intermediate; week 6) and Visit 3 (final; week 12).
详细描述
The three visits that make up the study and the actions to be carried out in each of them are described below:
Visit 1 (initial; week 0)
Once the informed consent is signed, a doctor trained for the study performs the initial interview where it is verified that the patient meets all the inclusion criteria and none of the exclusion criteria and their medical history.The investigator will proceed to assign the patient the next study participant number and, according to a previously prepared randomization list, the treatment that they will receive during the study will be assigned.
The investigator will assess the severity and symptoms of rosacea according to the Investigator's Global Assessment (IGA) and Clinician Erythema Assessment (CEA) scales. The patient will also complete a questionnaire to assess the impact on quality of life due to the disease: Dermatology Life Quality Index (DLQI).
Visit 2 (intermediate; week 6)

结局指标
主要结局
Number and percentage of cases responding to the treatment according to the Investigator's Global Assessment (IGA) index score, comparing the baseline with the visits at 6 and 12 weeks
时间窗: 12 weeks
IGA index measures the severity of rosacea Score range is from 0 to 6 according to the severity of the disease 0=clear; 1=minimum; 2=mild; 3=mild-moderate; 4=moderate; 5=moderate-severe; 6=severe It will be considered a treatment response in IGA scale when the participant improves by at least 2 categories in this index and the final score is 0-1 points (clear and almost clear)
