David Kimberlin, MD, University of Alabama at Birmingham
  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.

Herpes Simplex Virus Drug: Novel Antiviral Drug Drug: Placebo Phase 1 Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment

Primary Outcome Measures:
  • Evaluate the safety and tolerability of CMX001 oral suspension in infants being treated for neonatal HSV CNS disease. [ Time Frame: Baseline through day 21 ]
  • Determine the plasma pharmacokinetics of the CMX001 and cidofovir following administration of CMX001 oral suspension in infants being treated for neonatal HSV CNS disease. [ Time Frame: Baseline through day 21 ]

Secondary Outcome Measures:
  • Explore a plasma drug concentration-response relationship between CMX001 exposure and quantity of HSV DNA in cerebrospinal fluid (CSF) at Day 4 of antiviral therapy [ Time Frame: Baseline through day 21 ]
  • Explore a plasma drug concentration-response relationship between cidofovir exposure and quantity of HSV DNA in cerebrospinal fluid (CSF) at Day 4 of antiviral therapy [ Time Frame: Baseline through day 56 (end of study) ]

Enrollment: 0
Study Start Date: January 2016
Estimated Study Completion Date: June 2017
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Novel Antiviral Drug
Subjects will be randomized to receive one of 3 oral doses of a Novel Antiviral Drug: 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 3 oral doses of placebo matched in volume to active drug: 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.
