FDA approves boceprevir for HCV genotype-1 |
The FDA has approved boceprevir for the treatment of chronic hepatitis C virus genotype-1 infection combined with peginterferon alfa and ribavirin in adult patients with compensated liver disease previously untreated or who have failed previous therapy. As previously reported in Infectious Disease News, data from the HCV RESPOND-2 trial and the SPRINT-2 trial suggest that the addition of boceprevir (Victrelis, Merck) to peginterferon-ribavirin treatment resulted in significantly higher rates of sustained virologic response in patients previously treated and patients with previously untreated HCV genotype-1 vs. pegylated interferon and ribavirin alone. EDWARD COX, MD, MPH ADVERTISEMENT “Victrelis is an important new advance for patients with hepatitis C,” Edward Cox, MD, MPH, director of the FDA’s Office of Antimicrobial Products at the Center for Drug Evaluation and Research, said in a press release. “This new medication provides an effective treatment for a serious disease and offers a greater chance of cure for some patients’ hepatitis C infection compared to currently available therapy.” Boceprevir should be taken orally three times daily with food. The most common adverse events include fatigue, anemia, nausea, headache and dysgeusia. |

FDA approves boceprevir for HCV genotype-1
WEDNESDAY, MARCH 7, 2012CROI 2012: PSI-7977/ribavirin combo achieved rapid response in HCV genotype-1
SEATTLE — An interferon-free, experimental nucleotide analogue, PSI-7977, plus ribavirin for 12 weeks achieved rapid on-treatment response in hepatitis C virus genotype-1 patients and was well tolerated in this population, according to presenter Edward Gane, MD.
Gane, a hepatologist at Auckland City Hospital in New Zealand and principal investigator for the ELECTRON study, presented findings from a phase 2, multi-arm study aiming to assess the uridine nucleotide analogue, PSI-7977, combined with ribavirin currently in phase 3 development.
“Results on genotype-2 and genotype-3 patients were presented at the Liver meeting last fall, which demonstrated 100% rapid virologic response rates with interferon-free PSI-7977 plus ribavirin,” Gane said during a press conference today. “Following these results, we enrolled additional patients who were genotype-1 treatment-naive and null responders.”
For the current study, Gane and colleagues assigned 400 mg PSI-7977 plus ribavirin to 10 null responders and 25 treatment-naive patients with HCV genotype-1. Researchers compared early on-treatment data with data from treatment-naive patients with HCV genotype-2 and genotype-3 included in the ELECTRON study.
“Treatment-naive patients just completed treatment,” Gane said. “Therefore, results will not be available until next quarter and will be presented at the Liver meeting in Europe.”
However, overall data, thus far, indicate that patients achieved rapid treatment response, and among all participants, HCV RNA remained undetectable at 4 weeks and throughout the treatment regimen.
Of the nine null patients who have reached the 4-week treatment time point, eight patients relapsed. The one responder was a young, white woman who had the IL28 gene, a favorable predictor for response to interferon-based treatment, according to Gane.
“The majority of null responders have relapsed post-treatment. Further treatment options in this very difficult to treat group will either be longer duration of PSI-7977 plus ribavirin or the addition of another direct-acting antiviral,” he said.

Over-the-Counter Painkillers and the Liver
Over-the-Counter Painkillers and the Liver
Known commonly as Tylenol, acetaminophen is a common, mild to moderate pain reliever. As published in a 2005 edition of the journal Hepatology, U.S. researchers found that over a six-year time span, more than 40 percent of acute liver failure cases were caused by an acetaminophen overdose. High doses of acetaminophen can cause liver injury, even to a healthy liver, so those with fewer functioning liver cells have an even greater risk of harm. In limited dosages, a physician will generally only suggest acetaminophen to someone whose hepatic metabolism is fully functioning.
A non-steroidal anti-inflammatory drug (NSAID), ibuprofen reduces high body temperature, is an anti-inflammatory and inhibits normal platelet function. Available in products such as Motrin, Advil and Nuprin, ibuprofen is the painkiller of choice for millions of people. However, NSAIDS are known to cause gastrointestinal upset and bleeding. For those prone to portal hypertension (a common liver disease complication), the risk of gastrointestinal bleeding is intensified with NSAIDS. Studies have shown that at certain dosages, ibuprofen can stress the liver and elevate liver enzymes in people with chronic liver disease. As such, ibuprofen must be used with extreme caution (and always taken with food) in the later stages of liver disease.
Sometimes used as a preventative for cardiovascular disease, aspirin reduces fever, relieves pain, is an anti-inflammatory and a blood thinner. Also sold under the brand names Bayer, Anacin and Excedrin, aspirin limits the blood clotting process and prolongs bleeding. In chronic liver disease where the body’s production of clotting factors is naturally decreased, aspirin can increase the risk of bleeding. When taken in high doses (more than 2,000 mg per day) aspirin can cause liver injury.
