Frequently asked questions about Pevifoscorvir

What is pevifoscorvir?

Pevifoscorvir is an investigational small molecule antiviral being developed for the treatment of chronic hepatitis B infection. It is also known as pevifoscorvir sodium, or by the code ALG-000184. It is a Phase 1 clinical-stage candidate and has received Fast Track and Breakthrough Therapy designations from the FDA.

What is pevifoscorvir used for?

Pevifoscorvir is being developed for chronic hepatitis B infection. Both completed Phase 1 trials enrolled participants with chronic hepatitis B infection or evaluated the drug in volunteers with renal or hepatic impairment relevant to that patient population. It has not been approved for any use and remains investigational.

Who makes pevifoscorvir?

Pevifoscorvir is developed by Aligos Therapeutics, Inc., which trades on the Nasdaq under the ticker ALGS. The company is the sponsor of the clinical program for pevifoscorvir sodium, also known as ALG-000184, in chronic hepatitis B infection.

What phase is pevifoscorvir in?

Pevifoscorvir is in Phase 1 clinical development. Two Phase 1 trials have been completed, and neither is currently active. The drug is investigational and has not been approved by the FDA for chronic hepatitis B infection or any other indication.

What clinical trials is pevifoscorvir in?

Two completed Phase 1 trials have studied pevifoscorvir sodium. NCT07342881 evaluated single-dose pharmacokinetics, safety and tolerability in participants with renal impairment and healthy participants with normal renal function, enrolling 12. NCT07342868 evaluated single-dose pharmacokinetics, safety and tolerability in subjects with moderate hepatic impairment and healthy subjects with normal hepatic function, enrolling 20.

Is pevifoscorvir the same as ALG-000184?

Yes. Pevifoscorvir is also known as pevifoscorvir sodium and by the development code ALG-000184. These names refer to the same investigational small molecule antiviral from Aligos Therapeutics that is being studied in chronic hepatitis B infection.
