Phase I/II Study of High-Dose Acyclovir for Central Nervous System or Disseminated Neonatal Herpes Simplex Virus Infection

This study has been completed.

Office of Rare Diseases (ORD) Identifier:
First received: February 24, 2000
Last updated: June 23, 2005
Last verified: March 1999

OBJECTIVES: I. Evaluate whether high-dose acyclovir decreases acute and long-term morbidity and mortality in neonates with central nervous system or disseminated herpes simplex virus (HSV) infection.

II. Evaluate whether high-dose acyclovir is safe and tolerated in the newborn. III. Assess resistance to antiviral medication. IV. Amplify disease classification for the purpose of predicting prognosis. V. Assess any changes in viral excretion patterns. VI. Evaluate whether antigens and antibodies specific for HSV glycoproteins within the cerebrospinal fluid (CSF) predict long-term neurologic outcome.

VII. Evaluate whether specific antigens and antibodies in the CSF appear late after treatment and are indicative of insidious reactivation of virus in the brain.
