Brief summary
PICOLO is a double blind placebo controlled phase II dose ranging, dose escalating study in patients of Blalock-Taussig age categories (neonates and infants/toddlers), to determine the dose providing inhibition of platelet aggregation similar to adults.
Detailed description
There will be 3 blinded dose groups of 12 patients each (9 active, 3 placebo), central randomization, stratified by age (\< 1 month ;1 to 24 months). There will be a comparison of ADP-induced platelet aggregation at steady state.
