Primary outcome [1] 279511 0
The primary objective is to evaluate the duration of cold sore episodes in subjects treated with AH as compared with placebo.
Timepoint [1] 279511 0
From the date and time of prodromal symptom onset until the date and time the subject self-assessed the lesion was healed.
Secondary outcome [1] 287772 0
To evaluate the efficacy of AH in preventing or blocking cold sore lesion development. This will be assessed by a subject diary recording of progression and duration of cold sore development. Also by Investigator clinical assessment.
Timepoint [1] 287772 0
From the date and time of prodromal symptom onset until the date and time the subject self-assessed the lesion was healed.
Secondary outcome [2] 287773 0
To evaluate the safety and tolerability of topical AH 50mg administered once daily for 5 days. This will be assessed by recording of adverse events, laboratory tests (haematology, biochemistry and urinalysis) and other clinical assessments (physical exam, vital signs and ECG).
Timepoint [2] 287773 0
From the date and time of prodromal symptom onset until the date and time the subject self-assessed the lesion was healed.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible subjects will be randomised (1:1 ratio) to receive either active abalone haemocyanin or placebo. Allocation will be concealed and done by a central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation is via Interactive Web Response System
Masking / blinding
Blinded (masking used)

Brief summary
Herpes labialis (cold sores) caused by herpes simplex virus type 1 (HSV-1) is a common condition affecting millions of people worldwide. The pathogenesis of the disease suggests that brief and early immunogenic therapy may be a logical approach.
Abalone Haemocyanin (AH) derived from live abalone. The literature and clinical data generated by the sponsor of this study, indicate that AH has the potential for prophylaxis and therapeutic treatment of all stages of oral herpes.
The proposed study is to look at the safety and effectiveness of topical AH for 5 days compared with placebo.
