Detailed description
Study phase III, randomized, double-dummy, placebo controlled, single-center, of regarding the non-inferiority of the medication BL3000, when compared to Pantogar® treatment of telogen effluvium in women. 326 female patients will be recruited for the study. They will be aged from 18 to 45 years old, not menopausal, diagnosed with telogen effluvium proven by Trichoscan, who meet the inclusion criteria and do not meet the exclusion criteria and who sign the Informed Consent Form. Patients will be divided into two treatment groups according to randomization: Group I: 163 patients will receive treatment with the medication BL3000 and matching placebo of pantogar. Group II: 163 patients will receive treatment with the reference drug (Pantogar®) and matching placebo of BL3000. The patients will participate in the study for a period of 199 (one hundred and ninety-nine) days, using of the investigational or comparative product for 180 (one hundred and eighty) days,

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Rate difference of anagen hairs at 180 days (FA vf [%]) from baseline rate (FA vi [%]), in participants of each treatment group. | 180 days | Assess the non-inferiority of the effectiveness of the BL3000 drug compared to the drug. The counting of anagen and telogen performed by phototrichogram in the initial and final experimental times, with the calculation proposed according to the protocol below: The primary variable of efficacy will be the rate of anagen hairs (FA) (%), 45.90 and 180 days in relation to the beginning, between the two arms of treatment (test versus control). Calculated as follows: FA (vi): result of anagen (%) on visit 04 (T0); FA (vf): result of anagen (%) on visit 10 (T182). Response rate of anagen (%), FA = (FA (vf)-FA (vi)). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Difference of the number of anagen hairs per mm² (density) at the experimental time frames, compared to the baseline evaluation, in participants of each treatment group. | 45,90 and 180 days | Difference of the density of anagen hairs, in a given area (units per mm2), measured by phototrichogram in the experimental times, compared to the baseline measurement |
| Difference of the number of telogen hairs per mm² (density) at the experimental time frames, compared to the baseline evaluation, in participants of each treatment group. | 45,90 and 180 days | Difference of the density of telogen hairs, in a given area (units per mm2), measured by phototrichogram in the experimental times, compared to the baseline measurement |
| Difference of the anagen/telogen hair ratio at the experimental times frames, compared to the baseline evaluation, in participants of each treatment group. | 45,90 and 180 days | Difference of the anagen/telogen hair ratio, in a given area (units per mm2), measured by phototrichogram in the experimental times, compared to the baseline measurement |
| Difference of the total count of strand hair per mm² (density) at the experimental time frames, compared to the baseline evaluation, in participants of each treatment group. | 45,90 and 180 days | Difference of the density of the strand hair, in a given area (units per mm2), measured by phototrichogram in the experimental times, compared to the baseline measurement |
| Proportion of Excellent and Very good change of the telogen effluvium, as assessed by the investigator, comparing photographs taken at final visit and baseline visit, in participants of each treatment group. | 180 days | Analysis photographs taken during the initial and final visits, the opinion of the evaluator, regarding the improvement of the telogen effluvium: 1. \- Excellent; 2. \- Very good; 3. \- Good; 4. \- Regular 5. \- Bad. Analysis global assessment of the investigator, the X2 test will be used to make comparisons between groups. The proportion of Excellent and Very good for Researcher question will be analyzed, the confidence interval with 95% confidence for p1 - p2 will be constructed from the sample distribution of the sample proportion, where p2 is the proportion of Excellent and Very good by Pantogar for Researcher question and p1 is that of the test drug. |
| Proportion of Much better and best change, based on the participant's subjective assessment, from each treatment group, using a Likert scale. | 45,90 and 180 days | Participants will present their opinion on the effectiveness of the treatment, using a Likert scale from 1 to 4: Considering the evolution of the treatment, what is your opinion about the amount of hair strands at the end of the treatment. 1 - Much better; 2 - Best; 3 - No change and 4 - Worse. To analyze Subjective evaluation of the patient, the X2 test will be used to make comparisons between groups. The proportion of Much better and Best for patient question will be analyzed, the confidence interval with 95% confidence for p1 - p2 will be constructed from the sample distribution of the sample proportion, where p2 is the proportion of Very best and Best of Pantogar for patient question and p1 is that of the test drug. |
| Number of participants with treatment-related adverse events in each treatment group | 180 days | Safety and tolerability evaluation based on the occurrence of adverse events in each treatment group. |
| Difference of the strand hair thickness (mm²) at the experimental time frames, compared to the baseline evaluation, in participants of each treatment group. | 45,90 and 180 days | Difference of the thickness of strand hairs, measured by phototrichogram in the experimental times, compared to the baseline measurement |
