- New extended-release formulation is the first all-oral, co-formulated treatment containing the three direct-acting antiviral components of VIEKIRA PAK® for adult patients with genotype 1 (GT1) chronic hepatitis C virus (HCV) infection
- The approval marks another milestone in AbbVie's ongoing commitment to therapeutic innovation for people living with GT1 HCV
NORTH CHICAGO, Ill., July 25, 2016 /PRNewswire/ -- AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced that the U.S. Food and Drug Administration (FDA) has approved a New Drug Application (NDA) for VIEKIRA XR™ (dasabuvir, ombitasvir, paritaprevir and ritonavir) extended-release tablets. VIEKIRA XR is a once-daily, extended-release co-formulation of the active ingredients in VIEKIRA PAK® (ombitasvir, paritaprevir, and ritonavir tablets; dasabuvir tablets) and is for the treatment of patients with chronic genotype 1 (GT1) hepatitis C virus (HCV) infection, including those with compensated cirrhosis (Child-Pugh A). VIEKIRA XR is not for people with decompensated cirrhosis.
VIEKIRA XR is the first co-formulated three direct-acting antiviral (DAA) treatment for adult patients with GT1 HCV. VIEKIRA XR is given once-daily as three oral tablets and must be taken with a meal. It is used without ribavirin (RBV) in GT1b patients and in combination with twice daily RBV in GT1a patients. The approval is supported by Phase 3 clinical trials for VIEKIRA PAK which include data that demonstrated 100 percent sustained virologic response 12 weeks following treatment (SVR12) in GT1b patients with 12 weeks of therapy without ribavirin and 95 percent SVR12 in GT1a patients when used with ribavirin for 12 or 24 weeks of therapy.
"AbbVie's work continues to contribute to the transformation of hepatitis C care through our focus on evolving our current therapies as part of our ongoing commitment to patients," said Rob Scott, M.D., vice president, development and chief medical officer, AbbVie. "The approval of VIEKIRA XR provides a new treatment option for genotype 1 hepatitis C patients in the U.S. with clinical trial data using the components of VIEKIRA XR demonstrating 100 percent cure rates in genotype 1b patients."
There are six major HCV genotypes (GT1-6) and GT1 is the most prevalent form of HCV in the U.S., accounting for approximately 74 percent of all cases.1 Hepatitis C continues to be an important public health issue, with the Centers for Disease Control and Prevention (CDC) estimating that in the U.S. approximately 2.7 million people are chronically infected with HCV.2
The approval of VIEKIRA XR is supported by data from seven Phase 3 clinical trials in more than 2,300 patients who received VIEKIRA PAK with or without RBV for 12 or 24 weeks and two bioavailability studies comparing the formulations.
About Clinical Studies
The components of VIEKIRA XR (administered twice daily with a meal) have been studied in seven Phase 3 clinical trials where 1076 subjects (including 181 with compensated cirrhosis) received the recommended regimen of VIEKIRA +/? RBV for 12 weeks, or for 24 weeks in GT1a patients with compensated cirrhosis. Ninety-five to 100 percent achieved SVR12, which means the hepatitis C virus is not detectable in the blood three months after treatment ends. Cure rates varied by the subtype of hepatitis C and whether or not the person had cirrhosis. Individual results may vary.
USE
VIEKIRA XR™ (dasabuvir, ombitasvir, paritaprevir, and ritonavir) extended-release tablets/VIEKIRA PAK® (ombitasvir, paritaprevir, and ritonavir tablets; dasabuvir tablets) (VIEKIRA) are prescription medicines used with or without ribavirin to treat adults with genotype 1 chronic (lasting a long time) hepatitis C (hep C) virus infection.
VIEKIRA can be used in people who have compensated cirrhosis.
VIEKIRA is not for people with advanced cirrhosis (decompensated). If people have cirrhosis, they should talk to a doctor before taking VIEKIRA.
IMPORTANT SAFETY INFORMATION
When taking VIEKIRA in combination with ribavirin, people should read the Medication Guide that comes with ribavirin, especially the important pregnancy information.
What is the most important information to know about VIEKIRA?
⋅ VIEKIRA may cause severe liver problems, especially in people with certain types of cirrhosis. These severe liver problems can lead to the need for a liver transplant, or can lead to death.
⋅ VIEKIRA can cause increases in liver function blood test results, especially if people use ethinyl estradiol-containing medicines (such as some birth control products).
Ethinyl estradiol-containing medicines (combination birth control pills or patches, such as Lo Loestrin® FE, Norinyl®, Ortho Tri-Cyclen Lo®, Ortho Evra®; hormonal vaginal rings such as NuvaRing®; and the hormone replacement therapy medicine, Fem HRT®) must be stopped before starting treatment with VIEKIRA. If these medicines are used as a method of birth control, another method must be used during treatment with VIEKIRA, and for about 2 weeks after treatment with VIEKIRA ends. A doctor can provide instruction on when to begin taking ethinyl estradiol-containing medicines.
⋅ A doctor should do blood tests to check liver function during the first 4 weeks of treatment and then as needed.
⋅ A doctor may tell people to stop taking VIEKIRA if signs or symptoms of liver problems develop. A doctor must be notified right away if any of the following symptoms develop or if they worsen during treatment with VIEKIRA: tiredness, weakness, loss of appetite, nausea, vomiting, yellowing of the skin or eyes, color changes in stools, confusion, or swelling of the stomach area.
VIEKIRA must not be taken if people:

About VIEKIRA XR
The components of VIEKIRA XR* have been studied in a broad range of genotype 1 (GT1) patients with chronic hepatitis C virus (HCV) infection, ranging from treatment-naïve to difficult to treat patients, such as those with compensated (mild, Child-Pugh A) cirrhosis of the liver, HCV/HIV-1 co-infection, liver transplant recipients with normal hepatic function and mild fibrosis, and those who have failed previous treatment with pegylated interferon (pegIFN) and ribavirin (RBV).
The extended-release co-formulation of these components, VIEKIRA XR, consists of 200 mg of dasabuvir, 8.33 mg of ombitasvir, 50 mg of paritaprevir, and 33.33 mg of ritonavir per tablet, and is dosed three tablets once daily. VIEKIRA XR must be taken with a meal, and tablets should be swallowed whole. People should not drink alcohol within four hours of taking VIEKIRA XR. VIEKIRA XR is contraindicated in patients with moderate to severe hepatic impairment (Child-Pugh B and C) due to risk of potential toxicity. VIEKIRA XR is taken for 12 weeks, except in GT1a patients with cirrhosis and all liver transplant recipients with normal hepatic function and mild fibrosis, who should take it for 24 weeks. Ribavirin should be co-administered in GT1a patients and in all patients who have received a liver transplant.
Paritaprevir was discovered during the ongoing collaboration between AbbVie and Enanta Pharmaceuticals (NASDAQ: ENTA) for HCV protease inhibitors and regimens that include protease inhibitors. Paritaprevir is used in combination with AbbVie's ombitasvir with or without dasabuvir for the treatment of hepatitis C.
*Given as a fixed-dose combination of ombitasvir 25mg (an NS5A inhibitor), paritaprevir 150mg (an NS3/4A protease inhibitor), and ritonavir 100mg (an HIV-1 protease inhibitor), dosed once daily with a meal, and dasabuvir 250mg (a non-nucleoside NS5B palm polymerase inhibitor), dosed twice daily with a meal.

About HCV
Hepatitis C is inflammation of the liver caused by an infection with the hepatitis C virus. It is transmitted when an infected person's blood enters the bloodstream of an uninfected person. The Centers for Disease Control (CDC) estimates that approximately 2.7 million people have chronic HCV infection in the U.S. There are six major HCV genotypes (GT1-6), with genotype 1 (GT1) as the most prevalent form in the U.S. It is estimated that of people infected with chronic HCV, about 5 to 20 percent will go on to develop cirrhosis over a period of 20-30 years, and with HCV-related liver transplants on the rise, HCV is a critical public health issue. Presently, there is no vaccine for HCV infection.
