Reduction in SARS-CoV-2 viral load; based on the deep nasal swab sample as measured by a standardised RT-qPCR method after virus cultivation. Viral load will be expressed as relative amount of virions in samples after <br/ >treatment compared to before treatment (set to 100)Timepoint: From baseline (pre-dose) to 2 hours (h) post-dose]
