Study Endpoints
Primary Endpoints
Safety and Tolerability of a Single-dose of Famciclovir in Part A of the Study.
8 hours and 24 hours after study drug administration (Part A)

A patient with multiple adverse events (AEs) within the primary system organ class is counted only once in total row.

Maximum Observed Plasma Concentration of Penciclovir (Cmax)
plasma level measurements: pre-dose, 1, 2, 3, 4 and 5 hours post-dose

PK parameter; penciclovir is the active metabolite of famciclovir.

Time of Maximum Observed Plasma Concentration of Penciclovir (Tmax)
Plasma level measurements: pre-dose, 1, 2, 3, 4 and 5 hours post-dose

PK parameter; penciclovir is the active metabolite of famciclovir.

Area Under the Penciclovir Plasma Concentration-time Curve From Time 0 to Infinity (AUC0-∞)
Plasma level measurements: pre-dose, 1, 2, 3, 4 and 5 hours post-dose

PK parameter; penciclovir is the active metabolite of famciclovir.

Apparent Oral Clearance of Penciclovir (CL/F)
Plasma level measurements: pre-dose, 1, 2, 3, 4 and 5 hours post-dose

PK parameter; penciclovir is the active metabolite of famciclovir.

Apparent Terminal Elimination Half-life of Penciclovir (T1/2)
Plasma level measurements: pre-dose, 1, 2, 3, 4 and 5 hours post-dose

PK parameter; penciclovir is the active metabolite of famciclovir

Safety and Tolerability of Famciclovir Pediatric Oral Formulation in Part B of the Study.
Administered 2 times daily over 7 days

A patient with multiple AEs within the primary system organ class is counted only once in total row.

Pharmacokinetics of Single Dose - Tmax
Plasma samples were collected at 0.5, 1, 4 and 6 hours after dosing.

Measured by Tmax - The time after administration of a drug when the maximum plasma concentration is reached.

Pharmacokinetics of Single Dose - Cmax
Plasma samples were collected at 0.5, 1, 4 and 6 hours after dosing.

Measured by Cmax - The maximum plasma concentration of study medication

Pharmacokinetics of Single Dose - AUC(0-tlast)
Plasma samples were collected at 0.5, 1, 4 and 6 hours after dosing.

Measured by AUC(0-tlast) - Area under the plasma concentration time curve from time zero to the last quantifiable concentration-timepoint.

Pharmacokinetics of Single Dose - AUC(0-6h)
Plasma samples were collected at 0.5, 1, 4 and 6 hours after dosing.

Measured by AUC(0-6h) - Area under the plasma concentration time curve from time zero up to 6 hours post dose (i.e. the time of the last sample).

Secondary Endpoints
Overall Acceptability of Pediatric Oral Formulation by Patients in Part A of the Study.
Day 1, after swallowing the dose.
Overall Acceptability of Pediatric Oral Formulation by Patients in Part B of the Study.
Day 1 at clinic: after swallowing first dose
Overall Acceptability of Pediatric Oral Formulation by Patients in Part B of the Study
Day 8 at home: after swallowing last dose
