Trial Outcomes & Findings for Safety, Tolerability and PK of TPOXX in Adults Weighing More Than 120 KG (NCT NCT04392739)

NCT ID: NCT04392739

Last Updated: 2024-09-19

Results Overview

Area under the plasma concentration vs. time curve (AUC) from time 0 to the last quantifiable measurement following Day 7 dose administration. Samples were collected before the AM dose (0 hour), at 0.5, 1, 2, 4, 6, 8, 12 (before the PM dose), 14, 16, 18, 20, and 24 hours (Day 8, 24 hours after the AM dose on Day 7), and on Day 9 (48 hours after the AM dose on Day 7).
