Outcome Measures
Primary Outcomes (1)
Primary Efficacy Endpoint: The Area Under the Curve (AUC) of Total Symptom Score From Day 1 (Post Viral Challenge) to Day 8 (Quarantine Discharge).
Area Under the Curve (AUC) of total symptom scores (upper respiratory tract (URT), lower respiratory tract (LRT) and systemic viral symptoms (SVS)). Total symptom scores (from the symptom diary card) were used to calculate the AUC. The time unit used was minutes. Thus, the AUC unit is the total symptom score multiplied by the time period from first to last assessment in minutes (i.e score\*mins). The minimum AUC value would be 0, for a subject who did not report any symptoms. The maximum AUC value is not provided as it would be theoretical only, with no real meaning in terms of severity. Higher scores indicate worse outcome than lower scores.

Secondary Outcomes (5)
Secondary Efficacy Endpoint: Symptom Scores: Peak Symptoms Score
8 days
Secondary Efficacy Endpoint: Incidence(s) of Illness and Infection: Viral Shedding
8 days
Secondary Efficacy Endpoint: Incidence(s) of Illness and Infection: Seroconversion

Secondary Efficacy Endpoint: Viral Load Parameters: Area Under the Curve (AUC) of Viral Load, as Measured by Nasopharyngeal Swab RT-qPCR.
8 days
Secondary Efficacy Endpoint: Total Weight of Nasal Discharge Produced Post Viral Challenge to Quarantine Discharge

Study Arms (3)
Cohort A: Sentinel Group
OTHERSentinel group in which subjects received a challenge virus inoculum volume of 100uL on Day 0.
Cohort B: PrEP-001
EXPERIMENTALPrEP-001 6400μg dose administered equally over both nostrils and on 2 consecutive days, using a single dose nasal powder device, as per randomisation schedule.
Cohort B: Placebo
EXPERIMENTALNasal dose of placebo Comparator equally divided over both nostrils and on 2 consecutive days, using a single dose nasal powder device, as per randomisation schedule.
