Primary Outcome Measures
NameTimeMethod
Percentage of Participants With Healing by Day 88 days

The percentage of participants achieving lesion healing by Day 8 of study treatment

Secondary Outcome Measures
NameTimeMethod
Time to Healing29 days

The criteria for determining healing are as follows:

1. A condition where all erythematous and papular lesions, vesicular and pustular lesions, and erosive and ulcerative lesions have been resolved, and either the complete resolution of crusts or the complete epithelialization beneath any remaining crusts has been achieved.

2. In participants where no crust has formed, a condition characterized by the epithelialization of erosions/ulcers formation in mucosal lesions and potentially other affected areas.

3. In participants where no vesicles or pustules have formed, a condition characterized by the complete resolution of all erythematous and papular lesions.

Time to Complete Crusting29 days

The criteria for complete crust formation are outlined as follows:

1. A condition where all erythematous and papular lesions, vesicular and pustular lesions, and erosive and ulcerative lesions have been resolved, and all rashes are crusted (epithelialization beneath is not required).

2. In participants where no crust has formed, a condition characterized by the epithelialization of erosions/ulcers formation in mucosal lesions and potentially other affected areas.

3. In participants where no vesicles or pustules have formed, a condition characterized by the complete resolution of all erythematous and papular lesions.

Time to Virus Disappearance29 days

The day of viral disappearance is the first day on which the results of viral isolation continuously show 'HSV negative' until the final implementation day. The negative means that the results of the isolation and culture are negative, or the isolation and culture has not been performed due to complete crusting or healing of the lesion site.
