Metreleptin, a recombinant analog of the human hormone leptin, is an orphan drug used to treat complications of leptin deficiency in people with lipodystrophy. Lipodystrophies include a range of disorders characterized by the reduction, absence, or altered distribution of adipose tissue. Complications of lipodystrophy include metabolic abnormalities such as hypertriglyceridemia, insulin resistance, diabetes mellitus, and fatty liver disease. These metabolic abnormalities are often aggravated by excessive food intake, which is further aggravated by leptin deficiency, a protein secreted by adipose tissue. Administration of metreleptin results in improvement of metabolic symptoms including improvements in insulin resistance, reduced HbA1c and fasting glucose, reduced triglycerides, and reductions in food intake. Metreleptin is produced in _E. coli_ and differs from native human leptin by the addition of a methionine residue at its amino terminus. In February
Elbasvir is a direct-acting antiviral medication used as part of combination therapy to treat chronic hepatitis C, an infectious liver disease caused by infection with hepatitis C virus (HCV). HCV is a single-stranded RNA virus that is categorized into nine distinct genotypes, with genotype 1 being the most common in the United States, affecting 72% of all chronic HCV patients. Treatment options for chronic hepatitis C have advanced significantly since 2011, with the development of direct-acting antivirals (DAAs) such as elbasvir. Elbasvir is an inhibitor of NS5A, a protein essential for viral replication and virion assembly.[synthesis] The barrier to the development of resistance to NS5A inhibitors is lower than that of NS5B inhibitors, another class of DAAs. Substitutions at amino acid positions 28, 30, 31, or 93 are known to confer resistance to elbasvir. Despite this disadvantage elbasvir is still effective against HCV, particularly when paired with [grazoprevir]. Elbasvir is available as a fixed-dose combination product with [grazoprevir] (tradename: Zepatier) used for the treatment of chronic hepatitis C. Approved in January 2016 by the FDA, Zepatier is indicated for the treatment of HCV genotypes 1 and 4 with or without [ribavirin] depending on the presence of resistance-associated amino acid substitutions in the NS5A protein and previous treatment failure with [ribavirin], [peginterferon alfa-2a], [peginterferon alfa-2b], or other NS3/4A inhibitors like [boceprevir], [simeprevir], or [telaprevir]. Elbasvir and [grazoprevir] are used with or without [ribavirin] with the intent to cure, or achieve a sustained virologic response (SVR), and have been shown to achieve a SVR between 94% and 97% for genotype 1 and 97% and 100% for genotype 4 after 12 weeks of treatment.. SVR and eradication of HCV infection are associated with significant long-term health benefits including reduced liver-related damage, improved quality of life, reduced incidence of hepatocellular carcinoma, and reduced all-cause mortality. In a computational target-based drug repurposing investigation published in April 2020, elbasvir was predicted to bind stably and preferentially to three proteins necessary for viral replication of SARS-CoV-2, the human coronavirus responsible for the COVID-19 pandemic. While these results are suggestive of antiviral efficacy, follow-up clinical trials are required to validate elbasvir as a potential therapy against SARS-CoV-2.
