[3] [6] Ropeginterferon alfa-2b is the first medication approved by the US Food and Drug Administration (FDA) to treat polycythemia vera that people can take regardless of their treatment history, and the first interferon therapy specifically approved for polycythemia vera. [3] The FDA considers it to be a first-in-class medication. [7]
Pegylated interferon alfa-2b is a drug used to treat melanoma, as an adjuvant therapy to surgery. [3] Also used to treat hepatitis C (typically, in combination with ribavarin), it is no longer recommended due to poor efficacy and adverse side-effects. [4] Subcutaneous injection is the preferred delivery method. [3]
Interferon alfa-2b is an antiviral or antineoplastic drug. It is a recombinant form of the protein Interferon alpha-2 that was originally sequenced and produced recombinantly in E. coli [ 1 ] in the laboratory of Charles Weissmann at the University of Zurich , in 1980.
The gene encoding IFNα2, the IFNA2 gene, is clustered with all other type I IFN genes on chromosome 9 [8] and as all type I IFN genes, it is devoid of intron. [9] The open reading frame (coding sequence) of IFNA2 codes for a pre-protein of 188 amino acids with a 23 amino acid signal peptide allowing secretion of the mature protein.
Pegylated interferon alfa-2a, sold under the brand name Pegasys among others, is medication used to treat hepatitis C and hepatitis B. [3] For hepatitis C it is typically used together with ribavirin and cure rates are between 24 and 92%. [3] [4] For hepatitis B it may be used alone. [5] It is given by injection under the skin. [3] Side effects ...
Interferon alfa or HuIFN-alpha-Le, trade name Multiferon, is a pharmaceutical drug composed of natural interferon alpha (IFN-α), obtained from the leukocyte fraction of human blood following induction with Sendai virus. Interferon alfa contains several naturally occurring IFN-α subtypes and is purified by affinity chromatography.
The interferon-α/β receptor (IFNAR) is a virtually ubiquitous membrane receptor which binds endogenous type I interferon (IFN) cytokines. Endogenous human type I IFNs include many subtypes, such as interferons-α, -β, -ε, -κ, -ω, and -ζ.
Pegylated interferon (PEG-IFN) is a class of medication that includes three different drugs as of 2012: [1] Pegylated interferon-alpha-2a; Pegylated interferon-alpha-2b; Pegylated interferon beta-1a [2] In these formulations, Polyethylene glycol (PEG) is added to make interferon last longer in the body.
