Outcome Measures
Primary Outcomes (2)
Part 1: Optimal Dosing Level to Use in Part 2
Determine the best vitamin D supplementation level based on PK analysis of participants enrolled in Part 1. The PK of 25(OH)D after vitamin D supplementation in children will be characterized using a 2-compartment population PK model (popPK) with linear absorption and elimination kinetics.
20 weeks
Part 2: Proportion of Participants With Vitamin D Levels >= 40 ng/ml
Proportion of participants in part 2 who achieve vitamin levels \>= 40 ng/ml
16 weeks
