Zeroing in on the Hepatitis C Virus. The era of direct-acting antivirals (DAAs) that specifically target HCV began in 2011 with the U.S. Food and Drug Administration (FDA) approval of the first protease inhibitors.
How effective is interferon?
Patients achieving SVR have no detectable virus for at least 24 weeks after discontinuing the treatment—which means there is a very high probability that the treatment was successful and the patient will not relapse. Treating with interferon alone typically yielded SVR rates of less than 20 percent. Combining interferon with other antiviral drugs showed promise, however. One of these drugs, ribavirin, had first been tested by NIDDK intramural researchers as a stand-alone therapy, but it had only a modest and temporary effect on virus levels. However, later studies showed that a combination of interferon and ribavirin was superior to interferon alone, showing SVR rates of 30 to 40 percent. Another improvement came when scientists chemically modified interferon to make it last longer in the body. With SVR rates of 55 percent, this “pegylated” interferon (peginterferon), combined with ribavirin, became the standard of care for hepatitis C patients.
What is non-A, non-B hepatitis?
The non-A, non-B hepatitis virus was identified in 1989 by scientists at a California biotechnology company called Chiron who were collaborating with investigators at the Centers for Disease Control and Prevention (CDC). The research confirmed that this was a new virus—now officially called the hepatitis C virus, or HCV. This was a landmark advance in medicine that allowed for development of tests to detect HCV, which were rapidly applied to screen blood donations. Over the next few years, as the testing improved, HCV was effectively eliminated from the blood transfusion supply. The identification of HCV also led to further studies, undertaken by NIAID- and NIDDK-funded researchers and others, to determine its molecular structure. This was crucial for the design of drugs that would specifically interact with components of the virus and inhibit its replication. The identification of the virus also allowed for a more accurate diagnosis and a better sense of its prevalence; in fact, it was eventually determined that HCV was the most common cause of chronic hepatitis, cirrhosis, and liver cancer in the Western world.

How long did interferon therapy last?
The results of the trial were immediate and dramatic: most of the patients showed evidence of a healthier liver after a month of treatment. The patients relapsed when the interferon treatment was stopped after 4 months ; however, once the treatment was restarted, their liver health again improved and stayed normal even after the dose was gradually lowered and then stopped after a full year. Some of the patients had only minimal responses to interferon therapy, and others responded but then relapsed, but, in the end, half the patients in the trial showed no signs of liver infection in follow-ups that were eventually extended for 10 to 25 years. These were the first patients to be cured from the disease that would eventually be known as hepatitis C.
What are the genetics of HCV?
Studying HCV’s genetic makeup revealed that the virus has several genotypes, or genetic varieties, and these determine how effectively the virus responds to therapy. For example, genotype 1 is the most common genotype worldwide, but clinical trials found that it was more resistant to interferon-based therapy than other genotypes. The identification of different genotypes meant researchers were able to better predict and tailor therapies, and it provided one explanation for why some clinical trial participants had better outcomes with peginterferon than others. Another important consequence of identifying HCV was that researchers were now able to analyze the molecular components of the virus and determine which ones could be ideal targets for drugs. These potential targets included an HCV enzyme called a polymerase that is crucial for the replication of the virus’ genetic material; an enzyme called a protease that the virus uses to process its components before assembly; and a protein called NS5A, which appears to have several important roles in virus replication, including regulating the cell’s response to interferon.

How many different genotypes are there in hepatitis C?
One of the big challenges for hepatitis C is that there are a number of different forms of it, called genotypes. There are six different genotypes. They are different from each other, although in some ways they are the same.
Is hepatitis C the same as hepatitis C?
They are different from each other, although in some ways they are the same. Hepatitis C also has a high rate of viral replication, so it makes lots of new virus every day at a high rate and it doesn’t have a good way of proofreading its genome as it replicates, so it is always making errors.
Does hepatitis C cause liver cancer?
In curing this disease there are many, many downstream costs that are now eliminated because hepatitis C not only leads to severe liver damage and potential liver cancer —and is the cause of many, many liver transplants that exist in the U.S. and throughout the world—but also having hepatitis C leads to many other comorbidities like neurological problems and other issues caused by hepatitis C. So if you clear the virus, you eliminate these other problems and these patients can return to a pretty normal life after [treatment]. Getting access to the drug will really reap the benefit both from an economic standpoint and also from a burden on the health care system standpoint.
What was the first treatment for hepatitis C?
Antiviral medications were not the original treatment for hepatitis C. Before 2014, the only treatment for hepatitis C was called interferon and ribavirin, taken as weekly injections under the skin, plus pills.

How is hepatitis C treated?
Hepatitis C virus is treated with all-oral medications. These pills, called antiviral medications , are usually taken once per day. These antiviral medications are extremely good at attacking the virus and preventing it from multiplying.
What are the names of the medications for treating hepatitis C?
With the many options now available, often there is more than one good choice for a patient. Some of the treatments are recommended as first-line options, some are second-line options, and others are used less commonly in light of all the available choices.
What about patients with hepatitis C who also have hepatitis B?
Hepatitis B virus can flare in patients who are co-infected with hepatitis B and hepatitis C and are taking medication for hepatitis C. This has been reported as a potential risk for patients who are taking hepatitis C treatment and have underlying hepatitis B as well. The flare usually occurs within a few weeks after the patient starts taking medication for hepatitis C. Therefore, patients who have both hepatitis B and hepatitis C should be seen by a hepatitis expert before starting treatment of the hepatitis C; they may need to start taking hepatitis B treatment to avoid a hepatitis B flare.
How quickly will the medications work?
The medications will usually cause a very big drop in the viral load within the first two weeks. Some patients will see their viral load become undetectable very early, such as by the fourth week. For other patients, it can take longer until their viral load becomes undetectable.
Does a liver transplant cure hepatitis C?
A transplant provides a new working liver, but a transplant does not get rid of the hepatitis C virus in the patient. Patients with a liver transplant still need antiviral medication to cure their virus.
How long does it take to cure hepatitis C?

How long does it take for hep C to work?
New hep C treatments work in as short as 8 weeks. In the past, some people with hepatitis C had to stick with their treatment for a year. Because of the differences in how new medications work, most people are cured after 8 to 12 weeks of treatment, says Dr. Laryea. 3.
Why are hep C drugs less effective?
Older hep C medications were less effective at eliminating the infection from the body because they didn’t impact the virus itself. “Instead, they boosted the immune system’s ability to clear the virus,” explains Dr. Reau.
Why are older hep C medications less effective?
Older hep C medications were less effective at eliminating the infection from the body because they didn’t impact the virus itself. “Instead, they boosted the immune system’s ability to clear the virus,” explains Dr. Reau. That was also why they caused more side effects in general.
How many times can you treat hep C?
4. New hep C treatments usually cure people in one cycle. In the past, some people needed to be treated three or four times — something that put them “through hell,” says Laryea. “ Hepatitis C was complicated to treat,” she says. “Every patient required different combinations of medications for different lengths of time.
Do antiviral drugs kill viruses?
That’s all changed. The new antiviral medications directly target the virus and kill its ability to replicate, says Reau, allowing the body to effectively clear the residual bits and pieces of the virus.
Is modern medicine more effective than ever?
Modern treatments are more effective than ever and come with fewer side effects. “Rarely do we see such a radical development that has taken a disease that had a highly toxic profile to something that is highly curable,” says Nancy Reau, MD, a professor of transplant hepatology and gastroenterology at Rush University Medical Center in Chicago.
