Alisporivir (INN), or Debio 025, DEB025, (or UNIL-025) is a cyclophilin inhibitor. [1] Its structure is reminiscent of, and synthesized from ciclosporin.[ citation needed ]
It inhibits cyclophilin A. [2] Alisporivir is not immunosuppressive. [3]
It is being researched for potential use in the treatment of hepatitis C. [4] [5] [6] [7] [8] [9] [10] It has also been investigated for Duchenne muscular dystrophy [1] and may have therapeutic potential in Alzheimer's disease. [11]
Alisporivir is under development by Debiopharm for Japan and by Novartis for the rest of the world (licence granted by Debiopharm) since February 2010.[ citation needed ]
Hepatitis C is an infectious disease caused by the hepatitis C virus (HCV) that primarily affects the liver; it is a type of viral hepatitis. During the initial infection period, people often have mild or no symptoms. Early symptoms can include fever, dark urine, abdominal pain, and yellow tinged skin. The virus persists in the liver, becoming chronic, in about 70% of those initially infected. Early on, chronic infection typically has no symptoms. Over many years however, it often leads to liver disease and occasionally cirrhosis. In some cases, those with cirrhosis will develop serious complications such as liver failure, liver cancer, or dilated blood vessels in the esophagus and stomach.
The hepatitis C virus (HCV) is a small, enveloped, positive-sense single-stranded RNA virus of the family Flaviviridae. The hepatitis C virus is the cause of hepatitis C and some cancers such as liver cancer and lymphomas in humans.
Pegylated interferon alfa-2a, sold under the brand name Pegasys among others, is medication used to treat hepatitis C and hepatitis B. For hepatitis C it is typically used together with ribavirin and cure rates are between 24 and 92%. For hepatitis B it may be used alone. It is given by injection under the skin.
C-X-C motif chemokine ligand 10 (CXCL10) also known as Interferon gamma-induced protein 10 (IP-10) or small-inducible cytokine B10 is an 8.7 kDa protein that in humans is encoded by the CXCL10 gene. C-X-C motif chemokine 10 is a small cytokine belonging to the CXC chemokine family.
Pegylated interferon alfa-2b is a drug used to treat melanoma, as an adjuvant therapy to surgery. Also used to treat hepatitis C, it is no longer recommended due to poor efficacy and adverse side-effects. Subcutaneous injection is the preferred delivery method.
Boceprevir is a protease inhibitor used to treat hepatitis caused by hepatitis C virus (HCV) genotype 1. It binds to the HCV nonstructural protein 3 active site.
Telaprevir (VX-950), marketed under the brand names Incivek and Incivo, is a pharmaceutical drug for the treatment of hepatitis C co-developed by Vertex Pharmaceuticals and Johnson & Johnson. It is a member of a class of antiviral drugs known as protease inhibitors. Specifically, telaprevir inhibits the hepatitis C viral enzyme NS3/4A serine protease. Telaprevir is only indicated for use against hepatitis C genotype 1 viral infections and has not been proven to be safe or effective when used for other genotypes of the virus. The standard therapy of pegylated interferon and ribavirin is less effective than telaprevir in those with genotype 1.
miR-122 is a miRNA that is conserved among vertebrate species. miR-122 is not present in invertebrates, and no close paralogs of miR-122 have been detected. miR-122 is highly expressed in the liver, where it has been implicated as a regulator of fatty-acid metabolism in mouse studies. Reduced miR-122 levels are associated with hepatocellular carcinoma. miR-122 also plays an important positive role in the regulation of hepatitis C virus replication.
Sofosbuvir, sold under the brand name Sovaldi among others, is a medication used to treat hepatitis C. It is taken by mouth.
Simeprevir, sold under the brand name Olysio among others, is a medication used in combination with other medications for the treatment of hepatitis C. It is specifically used for hepatitis C genotype 1 and 4. Medications it is used with include sofosbuvir or ribavirin and peginterferon-alfa. Cure rates are in 80s to 90s percent. It may be used in those who also have HIV/AIDS. It is taken by mouth once daily for typically 12 weeks.
Ledipasvir is a drug for the treatment of hepatitis C that was developed by Gilead Sciences. After completing Phase III clinical trials, on February 10, 2014, Gilead filed for U.S. approval of a ledipasvir/sofosbuvir fixed-dose combination tablet for genotype 1 hepatitis C. The ledipasvir/sofosbuvir combination is a direct-acting antiviral agent that interferes with HCV replication and can be used to treat patients with genotypes 1a or 1b without PEG-interferon or ribavirin.
Faldaprevir was an experimental drug for the treatment of hepatitis C (HCV). It was being developed by Boehringer-Ingelheim and reached Phase III clinical trials in 2011. Boehringer announced in 2014 that it would not pursue approval of the drug any more because of better HCV treatments having become available.
Deleobuvir was an experimental drug for the treatment of hepatitis C. It was being developed by Boehringer Ingelheim. It is a non-nucleoside hepatitis C virus NS5B polymerase inhibitor. Deleobuvir was tested in combination regimens with pegylated interferon and ribavirin, and in interferon-free regimens with other direct-acting antiviral agents including faldaprevir.
Ombitasvir is an antiviral drug for the treatment of hepatitis C virus (HCV) infection by AbbVie. In the United States, it is approved by the Food and Drug Administration for use in combination with paritaprevir, ritonavir and dasabuvir in the product Viekira Pak for the treatment of HCV genotype 1, and with paritaprevir and ritonavir in the product Technivie for the treatment of HCV genotype 4.
Beclabuvir is an antiviral drug for the treatment of hepatitis C virus (HCV) infection that has been studied in clinical trials. In February 2017, Bristol-Myers Squibb began sponsoring a post-marketing trial of beclabuvir, in combination with asunaprevir and daclatasvir, to study the combination's safety profile with regard to liver function. From February 2014 to November 2016, a phase II clinical trial was conducted on the combination of asunaprevir/daclatasvir/beclabuvir on patients infected with both HIV and HCV. Furthermore, a recent meta-analysis of six published six clinical trials showed high response rates in HCV genotype 1-infected patients treated with daclatasvir, asunaprevir, and beclabuvir irrespective of ribavirin use, prior interferon-based therapy, or restriction on noncirrhotic patients, IL28B genotype, or baseline resistance-associated variants
Elbasvir is a drug approved by the FDA in January 2016 for the treatment of hepatitis C. It was developed by Merck and completed Phase III trials, used in combination with the NS3/4A protease inhibitor grazoprevir under the trade name Zepatier, either with or without ribavirin.
Elbasvir/grazoprevir, sold under the brand name Zepatier, is a fixed-dose combination for the treatment of hepatitis C, containing elbasvir and grazoprevir. It is used to treat chronic hepatitis C virus (HCV) genotypes 1 or 4 infection in both treatment-naïve and treatment-experienced patients.
Narlaprevir, is an inhibitor of NS3/4A serine protease, intended for the treatment of chronic hepatitis C caused by genotype 1 virus in combination with other antiviral drugs.
Interferon lambda 4 is one of the most recently discovered human genes and the newest addition to the interferon lambda protein family. This gene encodes the IFNL4 protein, which is involved in immune response to viral infection.
Merimepodib (VX-497) is a drug which acts as an inhibitor of the enzyme inosine monophosphate dehydrogenase, which is required for the synthesis of nucleotide bases containing guanine. This consequently inhibits synthesis of DNA and RNA, and results in antiviral and immunosuppressive effects. It progressed as far as Phase 2b human clinical trials against Hepatitis C but showed only modest benefits in comparison to existing treatments, however it continues to be researched, and also shows activity against other viral diseases such as Zika virus and foot and mouth disease virus.
