Activity of Valomaciclovir in Infectious Mononucleosis Due to Primary Epstein-Barr Virus Infection (Mono6)
This will be a randomized, placebo-controlled, double-blind single-center proof of concept study to evaluate the anti-EBV activity of 4 grams of valomaciclovir (2 grams BID) for 21 days in subjects with infectious mononucleosis documented to be caused by primary EBV infection. Otherwise healthy subjects (≥15 years old) referred to us with a clinical diagnosis of primary infectious mononucleosis will be screened and those with laboratory-confirmed primary EBV infection will be enrolled.

|Official Title:||Randomized, Placebo-Controlled, Double-Blind Study to Assess Clinical and Antiviral Activity of Valomaciclovir (EPB 348) in Infectious Mononucleosis Due to Primary Epstein-Barr Virus Infection (Mono 6)|
- To determine if treatment with valomaciclovir will significantly improve the clinical symptoms and reduce the viral burden in immunocompetent subjects with IM due to primary EBV infection. [ Time Frame: 21 days ] [ Designated as safety issue: Yes ]
- Evaluate the safety and tolerability of valomaciclovir. [ Time Frame: 15 ] [ Designated as safety issue: Yes ]

|Primary Completion Date:||July 2009 (Final data collection date for primary outcome measure)|
Active Comparator: Valomaciclovir
Valomaciclovir 2 grams orally twice daily for 21 days
4 grams orally of valomaciclovir (2 grams BID) for 21 days.
Placebo Comparator: placebo
placebo 2 tablets twice daily for 21 days
Placebo tablets orally twice daily for 21 days.
Subjects will be seen 2 times a week for 3 weeks and then weekly for 3 weeks. Clinical findings, clinical lab tests, EBV viral loads, and EBV antibody titers will be obtained at each clinic visit.
