Sofosbuvir for the Treatment of Genotype 1 Hepatitis C in Subjects Aged 65 Years Or Older
AMERICAN ASSOCIATION FOR THE STUDY OFLIVERD I S E ASES HEPATOLOGY, VOL. 63, NO. 4, 2016 Safety and Efficacy of Ledipasvir/ Sofosbuvir for the Treatment of Genotype 1 Hepatitis C in Subjects Aged 65 Years or Older Sammy Saab,1 Sarah H. Park,1 Masashi Mizokami,2 Masao Omata,3 Alessandra Mangia,4 Ed Eggleton,5 Yanni Zhu,5 Steven J. Knox,5 Phil Pang,5 Mani Subramanian,5 Kris Kowdley,6 and Nezam H. Afdhal7 Elderly subjects have been historically underrepresented in clinical trials involving antiviral hepatitis C therapies. The aim of this analysis was to retrospectively evaluate the safety and efficacy of ledipasvir/sofosbuvir (LDV/SOF) by age groups of <65 years versus 65 years among subjects enrolled in phase 3 trials. Four open-label phase 3 clinical trials evaluated the safety and efficacy of LDV/SOF with or without ribavirin (RBV) for the treatment of genotype 1 chronic hepatitis C virus. Sustained virological response at 12 weeks, treatment-emergent adverse events (AEs), and graded laboratory abnor- malities were analyzed according to age group. Of the 2293 subjects enrolled in four phase 3 trials, 264 (12%) were 65 years of age, of whom 24 were aged 75 years. Sustained virological response at 12 weeks was achieved by 97% (1965/ 2029) of subjects aged <65 years and 98% (258/264) of subjects aged 65 years. The most common AEs in both LDV/ SOF groups that occurred in 10% of subjects were headache and fatigue. The rate of study discontinuation due to AEs was similar in the two age cohorts. -

Anti-Inflammatory Effects of Amantadine and Memantine

To that end, we performed a literature search using the PubMed Database from 1966 up to October 31 2020, crossing the terms “amantadine” and “memantine” with “inflammation” and “anti-inflammatory”. Amantadine and/or memantine have shown anti-inflammatory effects in chronic hepatitis C, in neuroinflammation induced by sepsis and by lipopolysaccharides, experimental models of multiple sclerosis, spinal cord injury, and respiratory diseases. Since the inflammatory response is one of the main pathogenetic mechanisms in the progression of the SARS-CoV-2 infection, anti-inflammatory effects of amantadine and memantine could be hypothetically useful in the treatment of this condition. This potential utility deserves further research. Keywords: amantadine; memantine; anti-inflammatory effects; SARS-Cov-2; COVID-19; therapy 1. -
Antiviral Agents Active Against Influenza a Viruses
REVIEWS Antiviral agents active against influenza A viruses Erik De Clercq Abstract | The recent outbreaks of avian influenza A (H5N1) virus, its expanding geographic distribution and its ability to transfer to humans and cause severe infection have raised serious concerns about the measures available to control an avian or human pandemic of influenza A. In anticipation of such a pandemic, several preventive and therapeutic strategies have been proposed, including the stockpiling of antiviral drugs, in particular the neuraminidase inhibitors oseltamivir (Tamiflu; Roche) and zanamivir (Relenza; GlaxoSmithKline). This article reviews agents that have been shown to have activity against influenza A viruses and discusses their therapeutic potential, and also describes emerging strategies for targeting these viruses.

OBJECTIVE The intent of the Hepatitis C second generation antiviral Prior Authorization (PA) program is to appropriately select patients for therapy according to the Food and Drug Administration (FDA) approved product labeling and/or clinical guidelines and/or clinical studies. The PA process will evaluate the use of these agents when there is supporting clinical evidence of Class IIa, Level C or better for their use. Patients requesting Harvoni that are treatment naïve, non-cirrhotic and with an initial viral load < 6 M IU/mL will be approved for 8 weeks assuming all other criteria are met. This criteria does not include the use of Sovaldi (sofosbuvir), and requests for Sovaldi (sofosbuvir) in combination with Olysio (simeprevir) which will not be approved.

Interplay Between Hepatitis D Virus and the Interferon Response

The causative agent, hepatitis D virus (HDV), contains a small (approximately 1.7 kb) highly self-pairing single-strand circular RNA genome that assembles with the HDV antigen to form a ribonucleoprotein (RNP) complex. HDV depends on hepatitis B virus (HBV) envelope proteins for envelopment and de novo hepatocyte entry; however, its intracellular RNA replication is autonomous. In addition, HDV can amplify HBV independently through cell division. Cellular innate immune responses, mainly interferon (IFN) response, are crucial for controlling invading viruses, while viruses counteract these responses to favor their propagation. In contrast to HBV, HDV activates profound IFN response through the melanoma differentiation antigen 5 (MDA5) pathway. This cellular response efficiently suppresses cell-division-mediated HDV spread and, to some extent, early stages of HDV de novo infection, but only marginally impairs RNA replication in resting hepatocytes. In this review, we summarize the current knowledge on HDV structure, replication, and persistence and subsequently focus on the interplay between HDV and IFN response, including IFN activation, sensing, antiviral effects, and viral countermeasures. -

Viraferon, INN-Interferon Alfa-2B
SCIENTIFIC DISCUSSION This module reflects the initial scientific discussion for the approval of Viraferon. This scientific discussion has been updated until 1 August 2003. For information on changes after this date please refer to module 8B. 1. Introduction This was a full application to obtain a single European Marketing Authorisation via the centralised procedure for interferon alfa-2b. National Marketing Authorisations exist in all Member States for the use of interferon alfa–2b. Viraferon from SP Europe is indicated in the treatment of Chronic Hepatitis B, Chronic Hepatitis C. The harmonization of the SPC for the listed indications was achieved in June 1997 through a referral under Article 11 of Council directive 75/319/EEC as amended. The new data filed with the centralised application concerned an extension ofauthorised Chronic Hepatitis B approval in adults to children (1 to 17 years of age) and the combination of interferon alfa-2b with ribavirin as first line treatment for patients with Chronic Hepatitis C. The CPMP focused the evaluation on the new information provided in support of the centralised application. 2. Chemical, pharmaceutical and biologicals aspects longer The qualitative and quantitative composition of the centrally authorised medicinal product Viraferon and of the nationally licensed Viraferon, are strictly identical. The manufacturers and the manufacturing process are those already approved for the manufacture of the nationally authorised Viraferon. no This centralised application relates to three formulations: a lyophilised powder (containing human serum albumin as stabiliser) and two solutions for injection (vials and pens) which are Human Serum Albumin (HSA) free. The main goal of the development of the HSA-free formulation was to identify a stable interferon alfa- 2b solution free of human serum albumin and remains essentially free from visible particles. -

Virologic Response Rates of Weight-Based Taribavirin Versus Ribavirin in Treatment-Naive Patients with Genotype 1 Chronic Hepatitis C Fred Poordad,1 Eric Lawitz,2 Mitchell L. Shiffman,3 Tarek Hassanein,4 Andrew J. Muir,5 Bruce R. Bacon,6 Jamie Heise,7 Deanine Halliman,7 Eric Chun,7 and Janet Hammond7 Ribavirin-induced hemolytic anemia can prompt dose reductions and lower sustained virologic response (SVR) rates in the treatment of patients with chronic hepatitis C. The study aimed to determine if weight-based dosing of taribavirin (TBV), an oral prodrug of ribavirin (RBV), demonstrated efficacy comparable to RBV while maintaining its previ- ously demonstrated anemia advantage with fixed dose administration. A U.S. phase 2b randomized, open-label, active-controlled, parallel-group study was conducted in 278 treatment-naive patients infected with genotype 1 who were stratified by body weight and baseline viral load. Patients were randomized 1:1:1:1 to receive TBV (20, 25, or 30 mg/kg/ day) or RBV (800-1400 mg/day) with pegylated interferon alfa-2b for 48 weeks. The SVR rates in this difficult-to-cure patient demographics (mean age, 49 years; 61% male; 30% African American or Latino; high viral load; advanced fibrosis; and mean weight, 82 kg) were 28.4%, 24.3%, 20.6%, and 21.4% in the 20, 25, and 30 mg/kg TBV groups and the RBV group, respectively. There were no statistical differences in the efficacy analyses. Ane- mia rates were significantly lower (P < 0.05) in the 20 and 25 mg/kg/day TBV treatment groups (13.4% and 15.7%, respectively) compared to RBV (32.9%).
