In continuation of my update on ledipasvir and sofosbuvir (Harvoni-combination pill)
Harvoni, a daily pill that treats the most common form of hepatitis C, was approved by the U.S. Food and Drug Administration on Friday.
It's the first combination pill (ledipasvir and sofosbuvir) approved to treat the chronic infection, and the first medication that doesn't require that the antiviral drugs interferon or ribavirin be taken at the same time, the FDA said in a news release.
Both drugs in the combination pill interfere with the hepatitis C virus' ability to multiply. One of the drugs, sofosbuvir (Sovaldi) was approved in December 2013, while ledipasvir is a new antiviral, the agency said.
"With the development and approval of new treatments for hepatitis C virus, we are changing the treatment paradigm for Americans living with the disease," Dr. Edward Cox, director of the Office of Antimicrobial Products in the FDA's Center for Drug Evaluation and Research, said in the news release. "Until last year, the only available treatments for hepatitis C virus required administration with interferon and ribavirin. Now, patients and health care professionals have multiple treatment options, including a combination pill to help simplify treatment regimens."
One expert applauded Harvoni's approval.
"This is a giant step forward for people with [hepatitis C]. One pill, once daily, no interferon, no ribavirin and 94 to 99 percent cure! It moves the risk-benefit ratio needle way over toward benefit," said Dr. Douglas Dieterich, a professor of medicine in the division of liver diseases at The Mount Sinai Hospital in New York City.
However, price has been an issue with some of the new treatments for hepatitis C. For example, Sovaldi alone costs $1,000 a day and not all insurance companies cover the cost of treatment, experts have noted. Harvoni will cost $1,125 a pill, the Associated Press reported Friday.
Hepatitis C causes inflammation of the liver, which could spark other problems including diminished liver function (cirrhosis), scarring, liver cancer or liver failure. Most infected people aren't aware that they carry the virus until liver damage has occurred, the agency said.
Some 3.2 million Americans are believed to be infected with hepatitis C, the FDA said.
Harvoni was evaluated in three clinical studies involving more than 1,500 people who either hadn't been treated previously or hadn't responded to prior treatment. The most common side effects were fatigue and headache.
