Clinical Details

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

- 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
