General information about the trial
|
|||
Main objective of the trial |
This study was to evaluate the relative bioavailability of a pediatric granules formulation of ledipasvir/sofosbuvir (LDV/SOF) relative to tablet formulation in healthy participants and to evaluate the effect of concomitant food intake on the pharmacokinetics of a pediatric granules formulation of LDV/SOF.
|
||
Protection of trial subjects |
The protocol and consent/assent forms were submitted by each investigator to a duly constituted Independent Ethics Committee (IEC) or Institutional Review Board (IRB) for review and approval before study initiation. All revisions to the consent/assent forms (if applicable) after initial IEC/IRB approval were submitted by the investigator to the IEC/IRB for review and approval before implementation in accordance with regulatory requirements.
This study was conducted in accordance with recognized international scientific and ethical standards, including but not limited to the International Conference on Harmonization guideline for Good Clinical Practice (ICH GCP) and the original principles embodied in the Declaration of Helsinki.

Statistical analysis description |
A parametric mixed effect analysis of variance (ANOVA) model was used to estimate the geometric least-squares mean (GLSM) ratio (Treatment B/Treatment A) of the PK parameter and the corresponding 90% CI. Bioequivalence was concluded if the 90% CIs fell within the prespecified boundaries of 80% to 125%. "Subjects in this analysis" states 82; however, participants analyzed in PK analysis set were 40 for Treatment B and 42 for Treatment A.
