Candidate: Niclosamide

Type: Novel “optimized salt” formulation of antihelminthic drug approved as a treatment for parasitic infections

2021 Status: TFF Pharmaceuticals said October 28 that it received approval from Health Canada to begin a Phase 1 clinical trial of a dry powder formulation of niclosamide via a No Objection Letter (NOL) received six days earlier. TFF said it expected the first patient will be dosed in the study in November and that enrollment will be completed by early Q1 2022.

2020 Status: Union Therapeutics said April 12 it launched a program in partnership with Institut Pasteur Korea to test niclosamide, asserting that the drug showed potency more than 25 times higher than chloroquine and more than 40 times higher than Gilead Sciences’ remdesivir. A development program for niclosamide in COVID-19 being prepared for submission to Danish medical authorities, Union said. The drug is now the subject of a Phase IIb study in atopic dermatitis patients.

COVID-19: 300 Candidates and Counting

To navigate through the >300 potential therapeutic and vaccine options for COVID-19, GEN has grouped the candidates into four broad categories based on their developmental and (where applicable) clinical progress:

FRONT RUNNER – the most promising therapeutics/vaccines based on clinical progress, favorable data or both.

DEFINITELY MAYBE – earlier phases with promising partners, or more advanced candidates in development that have generated uneven data

KEEPING AN EYE ON… – interesting technology, attracting notable partners, or both, but preliminary data.

TOO SOON TO TELL – longshots pending additional experimental and/or clinical data.
