Trial Outcomes & Findings for Presatovir in Hematopoietic Cell Transplant Recipients With Respiratory Syncytial Virus Infection of the Upper Respiratory Tract (NCT NCT02254408)

NCT ID: NCT02254408

Last Updated: 2018-08-06

Results Overview

The time-weighted average change, often referred to as the DAVG, provides the average viral burden change from baseline. The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factor.

PRIMARY outcome

Timeframe: Baseline; Day 9

Population: Full Analysis Set: participants who received at least 1 full dose of study drug and had an RSV viral load greater than or equal to the lower limit of quantification of the quantitative real-time polymerase chain reaction (RT-qPCR) assay in the Day 1 nasal sample, as determined by RT-qPCR.

The time-weighted average change, often referred to as the DAVG, provides the average viral burden change from baseline. The mean values presented were calculated using the ANCOVA model and are adjusted for baseline value and stratification factor.
