- Primary Outcome Measures
Name Time Method Time of stop increasing new blisters/pimples 5 days after the first dose The number of days it took for the herpes to stop increasing (the original blisters/pimples enlarge, and the blisters/pimples increase) after the subjects were screened and enrolled.
Time of target herpes begins to scab 7 days after the first dose. The time taken for the target herpes (where the herpes first occurred when the patient was enrolled) begin to scab after the subjects were screened for enrollment.
Time of complete scabbing of all herpes 10 days after the first dose. The time taken for all the herpes to be completely crusted (the blisters have dried up and crusted) after the subjects were screened and enrolled.
