  Purpose

This study is to identify if a Novel Antiviral Drug could be used to treat babies with Herpes Simplex Virus (HSV) with central nervous system (CNS) disease. In this study the investigators will identify the best dose for young children as well as identify additional safety information about the Novel Antiviral Drug.

Primary Outcome Measures:
  • Plasma pharmacokinetic parameters for a Novel Antiviral Drug, including AUC24, maximum serum concentration (Cmax), half-life (T1/2), CL/F, and time to maximum concentration (Tmax) [ Time Frame: From baseline through visit day 21 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Clearance of HSV DNA from CSF by Day 4 of antiviral treatment of neonatal HSV disease [ Time Frame: baseline through visit day 21 ] [ Designated as safety issue: No ]
  • The incidence of SAEs and AEs considered to be related to study treatment [ Time Frame: Baseline through visit day 56 (end of study) ] [ Designated as safety issue: Yes ]
  • The incidence of grade 3-4 AEs and SAEs, with or without relationship to study treatment [ Time Frame: Baseline through visit day 56 (end of study) ] [ Designated as safety issue: Yes ]
  • Intracellular pharmacokinetic parameters for the active diphosphate moiety of a Novel Antiviral Drug in peripheral blood mononuclear cells (PBMCs) [ Time Frame: baseline through visit day 21 ] [ Designated as safety issue: No ]
  • Correlation of a Novel Antiviral Drug plasma and intracellular concentrations with qualitative and quantitative HSV detection in cerebrospinal fluid and blood by PCR [ Time Frame: baseline through visit day 21 ] [ Designated as safety issue: No ]

Estimated Enrollment: 32

Arms Assigned Interventions
Active Comparator: Novel Antiviral Drug
Subjects will be randomized to receive one of 4 oral doses of a Novel Antiviral Drug: 0.25 mg/kg/dose, 0.50 mg/kg/dose, 1.0 mg/kg/dose or 2.0 mg/kg/dose twice a week for up to 3 weeks during the time in which the 21 day administration of parenteral acyclovir is being administered
Drug: Novel Antiviral Drug
4 oral doses of a Novel Antiviral Drug: 0.25 mg/kg/dose, 0.50 mg/kg/dose, 1.0 mg/kg/dose or 2.0 mg/kg/dose twice a week for 3 weeks during the time in which the 21 day administration of parenteral acyclovir is being administered. Subjects will be assigned a the higher dose of study drug after the DSMB and sponsor determine that reported adverse events and the PK data show that it is safe to increase dosing to the next higher level.
Placebo Comparator: Placebo
Subjects will be randomized to receive one of 4 oral doses of placebo matched in volume to active drug: 0.25 mg/kg/dose, 0.50 mg/kg/dose, 1.0 mg/kg/dose or 2.0 mg/kg/dose twice a week for up to 3 weeks during the time in which the 21 day administration of parenteral acyclovir is being administered
Drug: Placebo
4 oral doses of placebo matching the a Novel Antiviral Drug assigned dose: 0.25 mg/kg/dose, 0.50 mg/kg/dose, 1.0 mg/kg/dose or 2.0 mg/kg/dose twice a week for 3 weeks during the time in which the 21 day administration of parenteral acyclovir is being administered. Subjects will be assigned a the higher dose of study drug after the DSMB and sponsor determine that reported adverse events and the PK data show that it is safe to increase dosing to the next higher level.

Detailed Description:

In this study, the pharmacokinetics and safety of a Novel Antiviral Drug will be determined in babies with neonatal HSV CNS disease. The study will be conducted at 18 academic medical centers throughout the United States. Young infants presenting with virologic confirmation of neonatal HSV infection and evidence of CNS involvement will be eligible for study enrollment. Study Day 1 is defined as the day when dose 1 of the Novel Antiviral Drug study medication is administered.

  Eligibility

Ages Eligible for Study:   up to 98 Days
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Signed Informed Consent by parent or legal guardian of study subject

  • Total bilirubin ≥ 5-times upper limit normal (ULN)
  • Infants known to be born to women who are HIV positive (HIV testing is not required for study entry)
  • Receipt of investigation drugs within 30 days prior to enrollment
