Frequently asked questions about Nitazoxanide

What is Nitazoxanide used for?

Nitazoxanide is an investigational small molecule being studied for use in patients with renal impairment and moderate hepatic impairment. It is in Phase 1 clinical development for these conditions, which fall under the gastrointestinal therapeutic area.

Who is developing Nitazoxanide?

Nitazoxanide is being developed by Genfit SA Sponsored ADR, a biopharmaceutical company. The company's stock is traded under the ticker symbol GNFT.

What phase is Nitazoxanide in?

Nitazoxanide is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. Its clinical trials are focused on evaluating its pharmacokinetics in patients with renal or hepatic impairment.

What clinical trials is Nitazoxanide in?

Nitazoxanide has completed two Phase 1 clinical trials. The first, NCT05116826, studied its pharmacokinetics in patients with moderate or severe hepatic impairment. The second, NCT05368935, studied its pharmacokinetics in subjects with renal impairment. Both trials were conducted in the United States.

Is Nitazoxanide the same as any other drug?

Nitazoxanide is the drug name used in clinical trials. No alternative names have been associated with this drug in the context of its development for renal and hepatic impairment.
