Study Design

Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description:

Phase I clinical trial, controlled, of parallel groups, double blind, randomized, exploratory.

Masking: Triple (Participant, Investigator, Outcomes Assessor)
Masking Description:

The blinding will correspond to the research subject and the principal investigator. In addition, the statistical analysis will be carried out in a blinded manner for the partial and final analysis.

The masking will be done using boxes in the primary packaging identical in the two groups. Blinding for the research subject and the researcher will be done by replacing the commercial labels in the case of the comparator in the bottles and the use of identical labels that contain the allocation number.

Blinding may be opened in the following cases:

1. Presence of a serious adverse event.
2. Safety alarm due to the use of the drugs under study.
3. In case the sponsor determines it for any reason of security or other reason that considers pertinent.
