Objectives: 1) To evaluate la proportion of hepatitic C virus (HCV)-monoinfected patients who show sustained virologic response (SVR) to treatment including direct-acting antivirals (DAAs) in the clinical practice in clinical units that treat infectious diseases and 2) to determine the frequency of adverse events, including those that are severe and/or cause treatment interruption, in DAA-based therapy in this setting.
Design: Multicentric, prospective post-authorised cohort study. Setting: Hospitals of the Hepatitis Study Group (GEHEP) of the Spanish Society of Infectious Diseases and Microbiology (SEIMC).
Study population: HCV-monoinfected patients that initiate DAA-based treatment outside clinical trials.
Variables: The primary efficacy outcome variable is the proportion of patients who reach undetectable HCV-RNA 12 weeks after the scheduled end of therapy (SVR12). The primary safety outcome variable is the percentage of subjects who discontinue therapy due to adverse events.
Statistical analysis: A descriptive study will be performed, as well as a double sensibility analysis of the frequency of SVR12 using both an intention-to-treat and an on-treatment approach. Those variables that are associated with SVR12 with a p-value <0.2 will be included in a logistic regression analysis in which SVR12 will be the dependent variable.

Peptide Aldehydes Incorporating Thiazol-4-yl Alanine Are Potent In Vitro Inhibitors of SARS-CoV-2 Main Protease

Article

Author: Edwards, Kyle ; Fischer, Conrad ; Saffran, Holly A. ; Feys, Jenson R. ; Tyrrell, D. Lorne ; Joyce, Michael A. ; Shields, Justin A. ; Garcia, Kassandra

The main protease of SARS-CoV-2 is an essential enzyme required for polyprotein cleavage during viral replication and thus is an excellent target for development of direct-acting antiviral compounds. Continued research efforts have elucidated several peptidic small molecules like GC376, boceprevir, and nirmatrelvir with potent anticoronaviral activity bearing optimized amino acid side chain residues. To reduce synthetic complexity and cost, we used simple chemical surrogates that were commercially readily available to develop new inhibitors that mimic the potency of these drug compounds. We synthesized and tested several analogue chimeras of GC376 and boceprevir that have surrogate residues at the P1 and/or P2 position in order to further improve target binding. Both P1 variants with either a nonpolar cyclobutyl or polar thiazol-4-yl alanine resulted in low-micromolar to submicromolar M^pro inhibitors with strong antiviral activity in cell assays.

In silico study of inhibition activity of boceprevir drug against 2019-nCoV main protease

Article

Author: Tiwari, Gargi ; Chauhan, Madan Singh ; Sharma, Dipendra

Abstract:

Boceprevir drug is a ketoamide serine protease inhibitor with a linear peptidomimetic structure that exhibits inhibition activity against 2019-nCoV main protease. This paper reports electronic properties of boceprevir and its molecular docking as well as molecular dynamics simulation analysis with protein receptor. For this, the equilibrium structure of boceprevir has been obtained by DFT at B3LYP and ωB97XD levels with 6-311+G(d,p) basis set in gas and water mediums. HOMO–LUMO and absorption spectrum analysis have been used to evaluate the boceprevir’s toxicity and photosensitivity, respectively. Molecular docking simulation has been performed to test the binding affinity of boceprevir with 2019-nCoV MPRO; which rendered a variety of desirable binding locations between the ligand and target protein’s residue positions. The optimum binding location has been considered for molecular dynamics simulation. The findings have been addressed to clarify the boceprevir drug efficacy against the 2019-nCoV MPRO.

Orthogonal dual reporter-based gain-of-signal assay for probing SARS-CoV-2 3CL protease activity in living cells: inhibitor identification and mutation investigation

Article

Author: Zhao, Liangliang ; Wang, Baogang ; Dong, Shuwei ; Zhang, Dongna ; Bei, Zhu-Chun ; Song, Yabin ; Wang, Hong ; Li, Qingyun ; Xu, Likun ; Yu, Huanhuan

ABSTRACTThe main protease (3-chymotrypsin-like protease, 3CLpro) of SARS-CoV-2 has become a focus of anti-coronavirus research. Despite efforts, drug development targeting 3CLpro has been hampered by limitations in the currently available activity assays. Additionally, the emergence of 3CLpro mutations in circulating SARS-CoV-2 variants has raised concerns about potential resistance. Both emphasize the need for a more reliable, sensitive, and facile 3CLpro assay. Here, we report an orthogonal dual reporter-based gain-of-signal assay for measuring 3CLpro activity in living cells. It builds on the finding that 3CLpro induces cytotoxicity and reporter expression suppression, which can be rescued by its inhibitor or mutation. This assay circumvents most limitations in previously reported assays, especially false positives caused by nonspecific compounds and signal interference from test compounds. It is also convenient and robust for high throughput screening of compounds and comparing the drug susceptibilities of mutants. Using this assay, we screened 1789 compounds, including natural products and protease inhibitors, with 45 compounds that have been reported to inhibit SARS-CoV-2 3CLpro among them. Except for the approved drug PF-07321332, only five of these inhibit 3CLpro in our assays: GC376; PF-00835231; S-217622; Boceprevir; and Z-FA-FMK. The susceptibilities of seven 3CLpro mutants prevalent in circulating variants to PF-07321332, S-217622, and GC376 were also assessed. Three mutants were identified as being less susceptible to PF-07321322 (P132H) and S-217622 (G15S, T21I). This assay should greatly facilitate the development of novel 3CLpro-targeted drugs and the monitoring of the susceptibility of emerging SARS-CoV-2 variants to 3CLpro inhibitors.

Merck & Co., Inc.'s Investigational Medicine Boceprevir Achieved Significantly Higher SVR Rates In Treatment-Failure and Treatment-Naïve Adult Patients with Chronic Hepatitis C Genotype 1 Compared to Control

BOSTON--(BUSINESS WIRE)--Merck reported today that final results from two pivotal Phase III studies of boceprevir, its investigational oral hepatitis C protease inhibitor, demonstrated significantly higher sustained virologic response (SVR)1 rates in adult patients who previously failed treatment (treatment-failure; HCV RESPOND-2) and in adult patients who were new to treatment (treatment-naïve; HCV SPRINT-2) for chronic hepatitis C virus (HCV) genotype 1 compared to control, the primary objective of the studies. The results for the primary endpoints of these studies, which were first reported in a news release in August 20102, and a broad range of further data analyses from these studies are being presented in oral and poster presentations at the 61st Annual Meeting of the American Association for the Study of Liver Diseases (AASLD).
