A Crossover Study to Evaluate Relative Bioavailability of Simeprevir Age-appropriate Oral Formulation Candidates Compared With 150-milligram (mg) Oral Capsule in Healthy Adult Participants

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to assess the relative bioavailability (the extent to which a drug or other substance becomes available to the body) of simeprevir (SMV) following single dose administration of age-appropriate oral formulation candidates compared to the 150 milligram (mg) capsule, and to assess the effect of food on the bioavailability of SMV following single dose administration of a selected age-appropriate oral formulation candidate.

Detailed Description
-----------------
This is a Phase 1, open-label (all people know the identity of the intervention), randomized (study medication assigned to participants by chance), 2-panel, 3-way crossover (participants will receive different interventions sequentially during the trial) study in healthy adult participants. Participants will be equally divided over 2 panels, and will not be randomized between panels. Participants will not be allowed to switch panels. The study consists of 3 parts: Screening Phase (that is, 28 days before study commences on Day 1); Open-label Treatment (in subsequent 3-treatment periods in each Panel, each separated with washout period of 7 days); and Post-Treatment Phase (up to 7 days after last study drug intake). The duration of the study per participant will be at least 19 days, screening and follow-up not included. All the eligible participants will be randomly assigned to 1 of the 6 treatment sequences in each Panel. In fasted conditions, study drug will be administered following a 10-hour overnight fast. In fed conditions, participants will also fast from food for 10 hours, but will consume a high fat/high calorie breakfast within a 30-minute period. Study drug will be administered 30 minutes after the start of breakfast. Participants will not be allowed to have food until at least 4 hours after study drug administration. Blood samples will be collected for evaluation of pharmacokinetics at pre-dose and post-dose of study treatment. Relative bioavailability of SMV formulations will be evaluated primarily. Participants' safety will be monitored throughout the study.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Maximum Plasma Concentration (Cmax) of Simeprevir (SMV) | The Cmax is the maximum observed plasma concentration of SMV. | Baseline up to 72 hours post-administration of study drug | 
| Time to Reach the Maximum Plasma Concentration (Tmax) of SMV | The Tmax is the time to reach the maximum observed plasma concentration of SMV. | Baseline up to 72 hours post-administration of study drug | 
| Area Under the Plasma Concentration-Time Curve From 0 to last (AUC[0-last]) Post Dose of SMV | AUC (0-last) from time 0 to the time of the last measurable (non-below quantification limit [BQL]) concentration, calculated by linear-linear trapezoidal summation. | Baseline up to 72 hours post-administration of study drug | 
| Area Under the Plasma Concentration-Time Curve From 0 to Infinite Time (AUC[0-infinity]) Post Dose of SMV | The AUC (0-infinity) is the area under the plasma concentration-time curve from time 0 to infinite time, calculated as the sum of AUC (0-last) and C(last)/lambda(z), in which AUC(0-last) is area under the plasma concentration-time curve from time zero to time of the last quantifiable concentration, C(last) is the last observed quantifiable concentration and lambda(z) is elimination rate constant. | Baseline up to 72 hours post-administration of study drug | 
| Elimination Rate Constant (Lambda [z]) of SMV | The Lambda (z) determined by linear regression of the terminal points of the ln-linear plasma concentration-time curve. | Baseline up to 72 hours post-administration of study drug | 
| Terminal Half-life (t[1/2]) of SMV | The t(1/2) is defined as 0.693/Lambda (z). | Baseline up to 72 hours post-administration of study drug | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants within Each Category of Taste Questionnaire | Participants will assess the palatability of the SMV formulations by Taste Questionnaire, Question 1 will assess sweetness, bitterness, flavor and overall taste of the formulation; and Question 2 consists of visual analog scale wherein participants will put a cross in the box beneath the scores, corresponding to the 5-point hedonic scale (dislike it very much; dislike it a little; not sure, like it a little, like it very much). | 5 to 15 minutes post administration of study drug (up to Day 19) | 
| Number of Participants with Adverse Events (AEs) and Serious AEs | An adverse event (AE) is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. | Screening up to follow-up (7 days after last dose administration) |
