The present invention relates to a new topical composition comprising niclosamide and/or oxyclozanide and to the use of said composition for the treatment or prevention of pyoderma or dermatitis in non-human mammals.

The invention relates to a halogenated salicylanilide selected from closantel, rafoxanide, oxyclozanide and niclosamide and derivatives thereof including salts, hydrates, esters and the like for use in the topical treatment or prevention of infections caused by Gram-positive bacteria such as Staphylococcus, in particular Staphylococcus aureus, and Streptococcus, in particular Streptococcus pyogenes. Grain positive bacteria treated with the halogenated salicylanilides exhibit a very low frequency of appearance of resistant mutants compared to commonly used topical antibiotics.

Disclosed are niclosamide formulations for use in the treatment and prevention of viral infection. In some embodiments, the infection is transduced by a coronavirus, including a SARS-Cov-2 virus.

The present invention provides new compositions and methods for treating prostate cancer, e.g., drug-resistant prostate cancer, such as anti-androgen drug (e.g., enzalutamide) resistant and/or castration resistant prostate cancer (CRPC). These new compositions include, but are not limited to, pharmaceutical compositions that include an AR-V7 inhibitor, such as niclosamide. Alternatively, these new compositions can include, but are not limited to, pharmaceutical compositions that include an AKR1C3 inhibitor, such as indomethacin. These new methods include, but are not limited to, methods of administering an AR-V7 inhibitor, such as niclosamide, and/or an AKR1C3 inhibitor, such as indomethacin, to treat patients having prostate cancer. The present invention also provides methods of inhibiting androgen receptor variant expression, e.g. AR-V7, and methods of killing cells expressing AR-V7. The present invention further provides methods of inhibiting AKR1C3 expression or activity, and methods of killing cells that express AKR1C3.
