Writing in the Lancet medical journal, researchers from The International Hepatitis Interventional Therapy Group report a new treatment for chronic HCV infection that uses a combination of interferon alpha-2b and a drug called ribavirin.
Currently a drug called interferon alpha-2b is given to patients for a 48-week period.
The drug is a synthetic version of interferon gamma-1b, a distant cousin of the more famous virus fighter used against hepatitis and cancer.
Doctors have been using a hormone called interferon in combination with anti-viral drugs for several years.
They found that the gene interacts with a key part of the immune system, a chemical called interferon gamma.
Their levels of a hormone called interferon-tau were far lower than normal.
Thirty-one percent of telaprevir patients who had gotten no benefit at all from previous treatments with the current hepatitis C regimen, a combination of interferon and antiviral drug ribavirin, had SVRs.
Zymogenetics' drug is a new version of interferon, called pegylated interferon lambda, that could have fewer side effects.
These are just four of the side effects of interferon, a standard drug used to treat the liver disease hepatitis C.
Whereas in patients with a more serious form of leprosy, a protein associated with a viral response - interferon-beta - was prominent.
BioMedicines of Emeryville, Calif. is testing its Omega interferon with a Duros pump, a titanium device that looks like the ink tube of a Bic pen.
Doctors told her she could never take interferon again-a big problem because the main hepatitis C regimens all use this protein.
In those with a milder form of the disease, they found a protein associated with a bacterial immune response - interferon-gamma.
Markowitz says the drug has modest potency, but is undergoing a trial in combination with interferon and ribavirin that may show better results.
Existing drug regimens are based on various genetically engineered versions of the natural immune system protein alpha interferon combined with a second chemical, ribavirin.
The researchers found that while two-thirds of infants with biliary atresia produced a cytokine called gamma-interferon, the protein was not found in any of the samples of infants with cholestasis.
Pegasys takes an old hepatitis C drug, interferon, and wraps it in a protective polymer coating of polyethylene glycol (PEG for short) that prevents the interferon from being broken down quickly in the body.
Two trials, published in the Lancet medical journal, compared the effectiveness of alemtuzumab with a first-choice drug, interferon beta-1a.
It has also improved on Rebetron with a drug called Peg-Intron, a "pegylated" combination of interferon and polyethylene glycol (Peg for short).
The MS drug Beta interferon and the Herceptin, a breast cancer drug, are widely prescribed, despite the fact NICE has not yet issued guidelines.
Human Genome Sciences is developing a drug, Albuferon, a combination of the human protein albumin and interferon.
Human Genome Sciences (nasdaq: HGSI - news - people ) is developing a drug, Albuferon, a combination of the human protein albumin and interferon.
The boost to one in particular, interferon-gamma, was sizeable, a 13.6 fold increase.
An anonymous pharmaceutical company on Celera's subscriber list is now working to see if the gene will produce an alpha interferon protein that might be used as a drug.
The standard interferon alpha-2b treatment three times a week.
But the ultimate goal is a two- to three-pill cocktail that could replace interferon and cure the vast majority with few side effects.
Not only is interferon-beta an ineffective weapon against bacteria, it can block the action of interferon gamma - which is when bacteria can gain a foothold, the researchers said.
By keeping levels of interferon constant, the pump doesn't give the virus a chance to replicate between doses.
In one experiment 60% of mice missing something called the gamma interferon receptor on their cells got tumors after being exposed to a carcinogen, versus only 15% of normal mice.
Interferon helps, despite the nasty side effects, because it works by a general antiviral mechanism that avoids these problems.
