Clinical Trial to Evaluate the Effect of a Probiotic Mixture on the Rosacea Evolution

Bionou Research, S.L.70 enrolled

Overview

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).

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) In this intermediate visit, in addition to assessing the symptoms of the disease with the detailed scales, the investigator will record the adverse events reported by the patient, as well as the concomitant treatments used. Also, the treatment compliance rate will be calculated by counting the capsules returned by the patient. Visit 3 (final; week 12) In the final visit, the same actions will be carried out as in the intermediate visit, evaluating the severity of the disease and the remaining capsules will be collected, to calculate treatment compliance, concomitant treatments and adverse events. Visit 4 (post-treatment follow-up; week 24) During this visit, the symptoms of the disease will be assessed with the two scales used in the study and the treatments that the patient has required during the 12 weeks after the end of the study treatment will be counted.

Outcomes

Primary Outcomes

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

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)

Time frame: 12 weeks

Secondary Outcomes

The treatments considered will be any topical or systemic treatment

Time frame: 12 weeks

Number and percentage of cases responding to the treatment according to the IGA index score, analyzing the cases that received systemic treatment, comparing the baseline with the visits at 6 and 12 weeks
