Limitations and caveats
The initial protocol planned for 256 patients, however due to difficulties in recruiting patients, the sample size was subsequently reduced to 175 patients, to obtain 140 evaluable patients.

Registered outcomes2

Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.

ListOutcomeTime frameDescription
PrimaryGMDS (Griffiths Mental Development Scale)12 months
GMDS for testing and estimate babies psychomotor development from birth to 2 years trough six subscales : Locomotor, Personal-social, Hearing and language, Eye-Hand coordination, Performance.Sub- and General Quotients (GDQ) standard score are based on a mean of 100 and a standard deviation of 16. For children with delayed development, which is the case for children with Down Syndrome, Quotient tables could be not used because sub- and General quotient floors at 50. For each subscale, a raw score was derived from the contributing items. Total raw score was obtained by adding subscale raw scores. Sum of all subscale raw scores was converted into a development age using correspondence table. Subscale and global development quotients were computed by dividing the development age by the chronological age multiplied by 100. For preterm infants, chronological age was corrected taking into account the gestational term. Higher QD's scores show a better psychomotor development outcome
SecondaryBL (Brunet Lezine Revised Scale)12 months
BL includes 4 subscales : Locomotor, Coordination, Language, Sociability. Subscale and global developpemental quotients were computed by dividing the developpemental age by the chronological age multiplied by 100. This kind of formula do not give a min-max outcome. Higher QD's scores show a better psychomotor developpement outcome.

Outcomes2

Each outcome the trial posted results for, in ClinicalTrials.gov's words.

TypeOutcomeTime framePopulationUnitsMeasured as
PRIMARYGMDS (Griffiths Mental Development Scale)12 months
The main analysis of the primary efficacy endpoint is the adjusted change from baseline in GDQ derived from the Griffith Mental Development Scales (GMDS) at 12 months analysed by ANCOVA adjusted for covariates. Expected Outcome : six points difference in GDQ between any of the three treatment group compared to placebo at 12 months from baseline.
