NORTH CHICAGO, Ill., April 8, 2015 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that 29 abstracts from its ongoing hepatitis C clinical development program have been accepted for presentation during The International Liver CongressTM (ILC) 2015 in Vienna, Austria from April 22-26. Data being presented include sub-analyses of the recently approved VIEKIRAX® (ombitasvir/paritaprevir/ritonavir tablets) + EXVIERA® (dasabuvir tablets), Phase 3b studies, including a head-to-head comparison of AbbVie's three direct-acting antiviral treatment with telaprevir-based therapy and Phase 2/3 studies investigating AbbVie's combination treatment in genotype 1 (GT1) and genotype 4 (GT4). Additionally, data from Phase 1 studies of ABT-493 and ABT-530 will be presented.
"We are pleased to present new investigational data at ILC that reinforces our broad HCV clinical development program beyond the approval of VIEKIRAX + EXVIERA," said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. "We are studying the diverse populations seen in clinical practice and expanding our research and development, including our new HCV pipeline compounds."
AbbVie's ongoing HCV pipeline development program focuses on investigating a pan-genotypic, ribavirin (RBV)-free, once-daily treatment that may also allow for treatment durations of as little as eight weeks. Preliminary results from a Phase 2b study (n=79) of ABT-493 and ABT-530 in non-cirrhotic GT1 patients receiving the RBV-free recommended regimen for 12 weeks demonstrated a sustained virologic response rate at four weeks post treatment (SVR4) of 99 percent (n=78/79). These results, announced for the first time today, included both GT1a and GT1b, treatment-naïve and pegylated-interferon and RBV prior null responders. Patients across both study arms were randomized to receive ABT-493 (200mg) and either 120mg or 40mg of ABT-530. To date, the most common (>5 percent) adverse reactions were fatigue, headache, nausea, diarrhea and anxiety. Data from these Phase 2b studies of ABT-493 and ABT-530 will not be presented at ILC 2015, and will be released at future medical congresses.

About VIEKIRAX® + EXVIERA®
VIEKIRAX + EXVIERA is approved in the European Union for the treatment of genotype 1 (GT1) chronic hepatitis C virus (HCV) infection, including patients with compensated cirrhosis. VIEKIRAX is approved in the European Union for the treatment of genotype 4 (GT4) chronic HCV infection.
VIEKIRAX consists of the fixed-dose combination of paritaprevir 150mg (NS3/4A protease inhibitor) and ritonavir 100mg with ombitasvir 25mg (NS5A inhibitor), dosed once daily, and EXVIERA consists of dasabuvir 250mg (non-nucleoside NS5B polymerase inhibitor) dosed twice daily taken with or without ribavirin, dosed twice daily. VIEKIRAX + EXVIERA is taken for 12 weeks with or without RBV, except in GT1a and GT4 patients with compensated cirrhosis, who should take it for 24 weeks.
Paritaprevir was discovered during the ongoing collaboration between AbbVie and Enanta Pharmaceuticals (NASDAQ: ENTA) for hepatitis C protease inhibitors and regimens that include protease inhibitors. Paritaprevir has been developed by AbbVie for use in combination with AbbVie's other investigational medicines for the treatment of chronic hepatitis C.
Additional information about AbbVie's hepatitis C development program can be found on www.clinicaltrials.gov.
VIEKIRAX is indicated in combination with other medicinal products for the treatment of chronic hepatitis C (CHC) in adults. EXVIERA is indicated in combination with other medicinal products for the treatment of chronic hepatitis C (CHC) in adults.
Important EU Safety Information Contraindications:
VIEKIRAX + EXVIERA are contraindicated in patients with severe hepatic impairment (Child-Pugh C). Patients taking ethinyl estradiol-containing medicinal products must discontinue them and switch to an alternative method of contraception prior to initiating VIEKIRAX + EXVIERA. Do not give VIEKIRAX with certain drugs that are sensitive CYP3A substrates or strong inhibitors of CYP3A. Do not give VIEKIRAX and EXVIERA with strong or moderate enzyme inducers. Do not give EXVIERA with certain drugs that are strong inhibitors of CYP2C8.
Special warnings and precautions for use:
VIEKIRAX and EXVIERA are not recommended as monotherapy and should be used in combination with other medicinal products for the treatment of hepatitis C infection.
Pregnancy and concomitant use with ribavirin When VIEKIRAX + EXVIERA are used in combination with ribavirin, women of childbearing potential or their male partners must use an effective form of contraception during the treatment and 6 months after the treatment. Refer to the Summary of Product Characteristics for ribavirin for additional information.
ALT elevations Transient elevations of ALT to >5x ULN without concomitant elevations of bilirubin occurred in clinical trials with VIEKIRAX + EXVIERA and were more frequent in a subgroup who were using ethinyl estradiol-containing contraceptives.
Use with concomitant medicinal products Use caution when administering VIEKIRAX with fluticasone or other glucocorticoids that are metabolized by CYP3A4. A reduction in colchicine dosage or interruption in colchicine is recommended in patients with normal renal or hepatic function. VIEKIRAX with or without EXVIERA is expected to increase exposure of statins so certain statins need to be discontinued or dosages reduced. Low dose ritonavir, which is part of VIEKIRAX, may select for PI resistance in HIV co-infected patients without ongoing antiretroviral therapy. HIV co-infected patients without suppressive antiretroviral therapy should not be treated with VIEKIRAX.
Adverse Reactions Most common (>20 percent) adverse reactions for VIEKIRAX + EXVIERA with RBV were fatigue and nausea.
