Brief summary

This is an open-label, dose-escalation phase I study to assess the safety and tolerability of siCoV/KK46 in healthy volunteers. The purpose of this study is to determine the maximum daily dose of siCoV/KK46 as a single agent in adult healthy participants. Based on preclinical data from this institution, the investigators hypothesize that SARS-CoV-2 inhibition with siCoV/KK46 could potentially reduce pulmonary inflammation, thereby improving COVID-19 patient outcomes.

Detailed description

This is an open-label, dose-escalation phase I study to assess the safety and tolerability of single and multiple doses of siCoV/KK46 in healthy male volunteers. This study include 3 cohorts received 3.7 mg, 11.1 mg, 22.2 mg of the siCoV/KK46, respectively, via inhalation route. All subjects will undergo scheduled safety and tolerability assessments while in the clinical unit and as outpatients to the end of the follow-up period.

Interventions

DRUGsiCoV/KK46

The modified phase I 3 + 1+1 study design was used in dose escalation from low dose to high dose to determine the maximum daily dose. Sequential assignment of Patient cohorts to one of three dose levels of inhaled siCoV/KK46: 3.7 mg, 11.1 mg, 22.2 mg.
