Trial Outcomes & Findings for Evaluate the PK, Safety, Tolerability of Ferric Maltol at 3 Dosage Levels in Paediatric Subjects With Iron Deficiency (NCT NCT03181451)

NCT ID: NCT03181451

Last Updated: 2021-10-06

Results Overview

Descriptive statistics and population PK analysis of maltol glucuronide Cmax from PK samples collected on Day 1. Each subject had 1 pre-dose (0h) and 2 post dose PK blood sampling between (0h, 0.5-1h, 1-2h, 2-3h, 3-4h, 4-6h). Subjects were assigned to PK blood sampling schedule. For each individual subject the PK blood sampling schedule was the same on Day 1 and Day 10.
