Read the detailed description

This is a multicenter, randomized, double-blind, parallel-group, active controlled comparative study of the safety and efficacy of 2 dosing regimens of FV-100 versus valacyclovir administered for 7 days in subjects with uncomplicated AHZ(acute herpes zoster). Subjects diagnosed with uncomplicated AHZ within 72 hours of lesion appearance and worst pain of 4 or greater at day 1, will be randomized (1:1:1) to one of three treatment groups and will begin study treatment at the Day 1 visit(within 72 hours of AHZ lesion appearance) to either: 1. FV-100 400mg QD, 2. FV-100 400mg BID(total daily dose of 800mg), or 3. Valacyclovir 1000mg 3 times a day for a total daily dose of 3000mg. Subjects will be monitored for adverse events through day 21. Efficacy assessments for lesion status and AHZ pain are captured til day 120.

What researchers measure

Primary outcomes

  1. The incidence of post-herpetic neuralgia(PHN) following treatment with 2 dose regimens of FV-100 compared to valacyclovir.

    efficacy measure

    Time frame: Day 1 to Day 120

Secondary outcomes

  1. Acute herpes zoster associated pain, as measured by Zoster Brief Pain Inventory(ZBPI)

    efficacy measure

    Time frame: Day 1 to Day 120

  2. The effect on lesion formation and healing of 2 dose regimens of FV-100 compared to valacyclovir

    efficacy measure

    Time frame: Day 1 to Day 120

  3. The number and classification of adverse events in 2 dosing regimens of FV-100

    Safety measure

    Time frame: Day 1 to Day 120

  4. The pharmacokinetic profile of the active metabolite of FV-100 after 7 days of dosing at 400mg QD versus compared with 400mg BID

    Pharmacokinetic

    Time frame: Day 1 to Day 120
