Recurrent cold sores - herpes simplex labialis (HSL) occurs in 20-40% of the US population

and patient seek treatment because of the discomfort and visibility of the lesion although it is a self limiting disease. The purpose of this study is to check the safety, Efficacy and convenience of Use of the Natural Agent "Superlysin Gel" as Treatment for Herpes Labialis in Comparison to Acyclovir 5% and Docozanole 10%.

Official title: The Safety, Efficacy and Convenience of Use of the Natural Agent "Superlysin Gel" as Treatment for Herpes Labialis in Comparison to Acyclovir 5% and Docozanole 10%.

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Factorial Assignment, Masking: Double-Blind, Primary Purpose: Treatment

Primary outcome: Reducing healing process and duration of cold sores using superlysin gel

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)

Minimum age: 18 Years. Maximum age: 70 Years. Gender(s): Both.
