About

The VISNAT trial is a PILOT STUDY due to absence of previous evidences in literature on using probiotic in newborns with perinatal asphyxia.

It is designed as a randomized, placebo-controlled, blinded, multicentre superiority trial with two parallel groups and a primary outcome of mortality and/or disability at 18 months of age.

After informed consent is obtained from both parents, randomization will be performed as block randomization with a 1:1 allocation using a computer-generated allocation sequence, while the allocation concealment will be performed using locked bags.

Randomization data and allocation list will be stored in a secure place and will not be available to any of the components of the study apart of data collectors.

Participant files will be stored for a period of 10 years after completion of the study.

All the components of the study will be blinded including: participants and their parents, healthcare providers, outcome assessors, data collectors, data analysts.
