Despite the availability of treatment options for HCV, some problem. The large, underserved population of people with hepatitis C continues to grow dramatically due to the opioid crisis, injection drug use, and hepatitis C virus reinfection.”

Details of the speech are as follows:

Poster number: 1861-A
title: Bemnifosbuvir and Ruzasvir are potent HCV DAAs with good antiviral properties against the major HCV NS5A and NS5B RAV and support combined use
Date and time: Friday, November 10, 1:00 pm – 2:00 pm
Place: Hall A

Poster number: 1879-A

About Bemnifosbuvir and Ruzasvir for the treatment of hepatitis C virus (HCV)

Atea is currently conducting a Phase 2 open-label study evaluating bemnifosbuvir in combination with ruzasvir (RZR) in patients with treatment-naïve HCV infection (without cirrhosis and/or compensated cirrhosis). This study was designed to evaluate the safety and efficacy of a pan-genotypic combination of once-daily benifobuvir 550 mg and RZR 180 mg for eight weeks. Approximately 280 treatment-naïve HCV-infected patients across all genotypes are expected to be recruited, including a lead-in cohort of 60 patients.

Bemnifosbuvir is a nucleotide polymerase inhibitor that has been shown to be approximately 10 times more active than sofosbuvir (SOF) in vitro A panel of laboratory strains and clinical isolates targeting HCV genotypes 1-5. in vitro Studies have shown that bemnifosbuvir is still fully active against SOF resistance-related strains (S282T), and its potency is 58 times higher than SOF. The pharmacokinetic (PK) profile of benifobuvir supports once-daily dosing for the treatment of HCV, and benifobuvir was well tolerated in healthy and HCV-infected subjects at doses up to 550 mg, sustained The duration is 8-12 weeks.

RZR is an oral NS5A inhibitor that has demonstrated potent pan-genotypic antiviral activity in preclinical (picomolar range) and clinical studies. RZR has been treated in more than 1,200 HCV-infected patients for 12 weeks at daily doses up to 180 mg and demonstrated a favorable safety profile. RZR’s PK profile supports once-daily dosing.
