Assessing the effects of liver impairment on new treatments for hepatitis

A Phase 1 Open-Label, Single-Dose, Parallel-Group Study of the Pharmacokinetics and Safety of VIR-2218 and VIR-3434 Monotherapy and Combination Therapy in Adult Participants With Hepatic Impairment

Phase 1 Interventional Vir Biotechnology, Inc. · NCT05484206

This study is testing how well two new drugs for hepatitis work and how safe they are for people with liver problems, specifically those with cirrhosis.

What this trial studies

This study evaluates the pharmacokinetics, safety, and tolerability of two investigational drugs, VIR-2218 and VIR-3434, in individuals with hepatic impairment, specifically those with cirrhosis. Participants will receive either a single dose of VIR-2218, VIR-3434, or a combination of both, with the aim of understanding how liver function affects drug exposure. The study will categorize participants based on the Child-Pugh-Turcotte scoring system to ensure appropriate grouping. Enrollment will occur in a non-randomized manner across multiple cohorts.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 to 70 with varying degrees of hepatic impairment and stable health conditions.

Not a fit: Patients with chronic HBV and HDV infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options for patients with hepatic impairment and hepatitis.

How similar studies have performed: Previous studies have shown promise in similar approaches, but this specific combination and focus on hepatic impairment is relatively novel.

Inclusion criteria: Hepatic impaired participants

* Apart from hepatic insufficiency, participants must, in the opinion of the Investigator be sufficiently healthy for study participation based on medical history, physical examination, vital signs, and screening laboratory evaluations
* Participant is considered to have chronic, stable moderate, severe, mild HI (of any etiology excluding chronic HBV and HDV) and has been clinically stable per Investigator assessment for at least 1 month prior to screening

Exclusion criteria: Participants with Hepatic impairment

* Not on stable dose and regimen of any medication
* Acute or worsening chronic hepatitis
* Participants requiring paracentesis more than once a month
