The present invention relates to novel therapeutic uses of niclosamide for the treatment of cancer. In particular, a combination of niclosamide or one of its derivatives with an alkylating agent is provided for the treatment of solid tumors. Moreover, niclosamide or one of its derivatives can be used for the treatment of solid tumors characterized by underexpression of NFKBIA. Finally, the invention relates to diagnostic methods for determining whether treatment with niclosamide alone or in combination with an alkylating agent is suitable for a cancer patient.

The invention relates to formulations comprising a halogenated salicylanilide, or a pharmaceutically acceptable salt thereof, and a cyclodextrin. The formulations may be in the form of a liquid formulation, particularly an aqueous formulation, and provide high concentrations of solubilised halogenated salicylanilide. Also disclosed a formulations in the form of powders and aerosols. Also disclosed are the formulations for use in the treatment of bacterial and viral infections, and the treatment of inflammatory diseases. The formulations are particularly suitable for administration by inhalation for the treatment of bacterial and viral pulmonary infections and the treatment of pulmonary inflammatory diseases.

This disclosure features compounds and compositions that are useful in methods of treating coronavirus infections (e.g., useful in methods of treating COVID-19) in a subject in need thereof. The methods include administering to the subject niclosamide compounds (or pharmaceutically acceptable salts and/or co-crystals thereof, e.g., niclosamide). In some embodiments, the niclosamide compounds have one or more properties that include, but are not limited to: a particular purity (e.g., a chemical purity of greater than about 99.0%) or a particular particle size (e.g., a particular particle size distribution and/or a particular particle size range and/or a specific surface area range). In an aspect, the niclosamide compounds described herein (e.g., niclosamide) can form part of compositions, dosage forms (e.g., unit dosage forms), and the like, which are suitable for respiratory administration (e.g., via inhalation and/or intranasally). In another aspect, the niclosamide compounds described herein (e.g., niclosamide) can form part of compositions, dosage forms (e.g., unit dosage forms), and the like, which are suitable for administration to the GI tract (e.g., orally or rectally such as via enema)).
