Detailed Description

Study design:

-Double blinded non-inferiority prospective parallel-group, intend to treat trial. Enrolment of 75 patients (25 randomized for each group). - Approval of the Institutional Ethical Review Board -

Study design:

- Patient characteristics (selected) and historical information assessment including: Race, average episode duration from patient history Duration of most recent previous episode Time since last onset of oral-facial herpes simplex Time since first onset of oral-facial herpes simplex Does patient experience localized prodrome?

  • Experiment duration; 5 to 10 days
  • 4 visits (days 1, 3,6,10)
  • 5 application /day for each derivative
  • Documentation Metric digital images of localized area signs at each visit Clinical assessment of prodrome/erythema, papule, vesicle, ulcer, crust, or healed skin (with or without residual erythema) Visual analogue scale (VAS) for subjective assessment of pain, burning, itching or tingling at each visit
  • Calculation of primary efficacy end point (time to healing); from the date and time of the initiation of therapy until the date and time of the clinic visit at which complete resolution of all local signs and symptoms, i.e. the lesion had aborted or complete healing had occurred (censored at day 10)
