Safety and Efficacy of Intranasal Administration of Niclosamide (UNI91103) in Adults With Asymptomatic or Mild COVID-19

Niclosamide is a broad spectrum, host targeting antiviral that inhibits viral replication (by neutralizing endosomal pH) and increases viral clearance (by increasing the autophagic flux). The niclosamide solution is administered directly to the nasal cavity via a nasal spray.

The placebo formulation contains purified water, sodium chloride as common isotonizing agent and the FAO/WHO approved colorant FD\&C Red 40 to match the red-orange colour of the active solution. The solution is administered directly to the nasal cavity via a nasal spray.
