General information

Niclosamide is an antihelmintic drug with potential antineoplastic activity (NCIt). It is on the World Health Organization Model List of Essential Medicines. The drug was shown to inhibit TMEM16F calcium ion channel/phosphatidylserine scramblase and to block SARS-CoV-2 Spike-induced Ca2+ oscillations, phosphatidylserine externalization, and syncytia formation (Braga et al., 2021).

The drug was identified based on its ability to prevent SARS-CoV-2-induced syncytia formation. Niclosamide inhibited SARS-CoV-2 replication in Vero cells with an IC50 of 0.34 μM. It displayed antiviral activity also in Calu-3 cells. The drug was shown to inhibit TMEM16F calcium ion channel/phosphatidylserine scramblase and to block SARS-CoV-2 Spike-induced Ca2+ oscillations and phosphatidylserine externalization.

Healthy volunteers

Administered as an inhaled nebulised formulation or intranasally. The treatment was safe. Mild and transient respiratory tract irritation was the most common adverse effect. Sample size: 34 + 10 placebo. Dosing: A single ascending dose or 5 doses in one subcohort. Primary outcome: Safety.
