Study 3 was an open-label, single-arm study to evaluate the pharmacokinetics, safety, and antiviral activity of a single 1500 mg dose three 500 mg tablets of famciclovir in children 12 to less than 18 years of age with recurrent herpes labialis. A total of 53 subjects were enrolled in the study; 10 subjects in the pharmacokinetic part of the study and 43 subjects in the non-pharmacokinetic part of the study.

Doctors usually collect a sample from small sores that are only a few days old. Viruses are more likely to be found in small newly formed sores. Famciclovir may be taken with or without food.

Clinical isolates of HSV and VZV with reduced susceptibility to acyclovir have been recovered from immunocompromised patients, especially with advanced HIV infection. While most of the acyclovir-resistant mutants isolated thus far from such patients have been found to be TK-deficient mutants, other mutants involving the viral TK gene TK partial and TK altered and DNA polymerase have been isolated. TK-negative mutants may cause severe disease in infants and immunocompromised adults.

The inhibitory activity of acyclovir is highly selective due to its affinity for the enzyme thymidine kinase TK encoded by HSV and VZV. This viral enzyme converts acyclovir into acyclovir monophosphate, a nucleotide analogue. The monophosphate is further converted into diphosphate by cellular guanylate kinase and into triphosphate by a number of cellular enzymes. In vitro, acyclovir triphosphate stops replication of herpes viral DNA. This is accomplished in three ways: 1 competitive inhibition of viral DNA polymerase, 2 incorporation into and termination of the growing viral DNA chain, and 3 inactivation of the viral DNA polymerase. In a randomized, double-blind, placebo-controlled trial conducted in 304 immunocompetent black and African American adults with recurrent genital herpes there was no difference in median time to healing between patients receiving Famciclovir or placebo.
