Herpes Simplex | Phase III Randomized Study of Oral Acyclovir in Infants With Herpes Simplex Virus Infection Involving the Central Nervous System

Herpes Simplex research study

What is the primary objective of this study?

OBJECTIVES: I. Determine the efficacy of long term suppressive therapy with oral acyclovir in infants with herpes simplex virus infection involving the central nervous system. II. Determine whether neurologic outcome is improved in these patients when treated with this regimen. III. Determine whether continuous administration of this drug suppresses recurrent skin lesions in these patients. IV. Determine the safety of this regimen in these patients.

Who is eligible to participate?
