Reporting Groups
  Description
Part A (Single-dose of Famciclovir) Includes 27 patients enrolled in Part A. Two adolescent patients (13 to 18 years) were enrolled in Part A of this study under an amendment to the protocol to include adolescent aged patients. The amendment was rescinded in compliance with an FDA Pediatric Written Request and no further adolescent aged patients were enrolled.
Part B (Multiple-dose of Famciclovir) Includes 47 patients enrolled in Part B. Part B started only after pharmacokinetic (PK) data from Part A had been analyzed. One patient that participated in Part A of the study also participated in Part B.

Reporting Groups
  Description
Part A (Single-dose of Famciclovir) Each patient in Part A received a single dose of famciclovir (12.5 mg/kg).
Part B (Multiple-dose of Famciclovir) Each patient in Part B received famciclovir twice a day (b.i.d.) approximately 12 hours apart for 7 days for a total of 14 doses. An 8-step dosing scheme (ranged from 150 mg b.i.d. to 500 mg b.i.d.) was used to determine the weight-based adjusted daily dose.
