Ombitasvir (ABT-267), a novel NS5A inhibitor for the treatment of hepatitis C
Expert Opin Pharmacother 2014 Dec;15(17):2609-22.PMID:25347030DOI:10.1517/14656566.2014.972364.
Introduction: Chronic hepatitis C infection is a global disease with 160 million people infected worldwide. Until recently, therapy was characterized by long duration, suboptimal success rates and significant adverse drug reactions. The development of direct-acting antivirals initiated a dramatic change in the treatment of hepatitis C. Areas covered: This review covers the development of the novel NS5A inhibitor Ombitasvir (ABT-267) and its clinical evaluation in Phase I to III trials as monotherapy and in combination with the NS3/4A inhibitor ABT-450/r and the non-nucleoside NS5B inhibitor dasabuvir (ABT-333) ± ribavirin. Expert opinion: Ombitasvir (ABT-267) is a potent inhibitor of the hepatitis C virus protein NS5A, has favorable pharmacokinetic characteristics and is active in the picomolar range against genotype 1 - 6. In patients with genotype 1 and 4, 12-week combination treatment with ombitasvir, dasabuvir and ABT-450/r plus ribavirin was highly effective and resulted in 12-week sustained virological response rates higher than 95% in treatment-naöve and treatment-experienced patients. In liver transplant recipients with genotype 1 hepatitis C, success rates in the same range can be expected after 24 weeks of treatment according to preliminary trial results. Genotype 1a patients with compensated cirrhosis who were prior nonresponders benefit from a treatment duration of 24 weeks.
ABT-450/ ritonavir and ABT-267 in combination with ABT-333 for the treatment of hepatitis C virus
Expert Opin Pharmacother 2015 Apr;16(6):929-37.PMID:25800085DOI:10.1517/14656566.2015.1024653.
Introduction: The global prevalence of chronic hepatitis C virus (HCV) is estimated to be 80 - 115 million and currently viremic infections account for 350,000 deaths annually. As the knowledge about HCV evolves, new anti-viral treatments have been developed. The primary goal of antiviral therapies has been to eradicate HCV virus from serum and achieve sustained virologic response (SVR). Historically, interferon has been a staple of nearly all HCV treatment regimens, despite significant toxic effects. Areas covered: In recent years, HCV treatment has changed rapidly and significantly. All-oral treatment regimens show promise for treatment with shorter duration and more manageable side effects. New antivirals aimed at improving SVR may provide a cure to nearly all HCV-infected patients. The unique combination of ABT-450 (paritaprevir) and ABT-267 (Ombitasvir) provides highly effective treatment for patients with genotype 1 HCV. This review will examine the antiviral properties, pharmacokinetics, pharmacodynamics, and side effects of these agents. Expert opinion: The combination of ABT-450/r and ABT-267 has improved potency, favorable side effect profile, and low risk of resistance compared to the first-generation protease inhibitors. This combination is likely to be a major part of novel upcoming HCV treatment regimens and is likely to be widely used by clinicians. Additional data is awaited in additional patient populations, and with possible shorter treatment durations.
Diagnosis and Management of Hepatitis C
Am Fam Physician 2015 Jun 15;91(12):835-42.PMID:26131943doi
Hepatitis C virus (HCV) infection, a major cause of chronic liver disease and cirrhosis, is predominantly transmitted by exposure to blood or body fluids. The infection progresses to a chronic state in 80% of patients, whereas the virus clears completely after the acute infection in 20% of patients. Screening for HCV with an anti-HCV antibody test is recommended for all adults at high risk of infection, and one-time screening is recommended in adults born between 1945 and 1965. If the anti-HCV antibody test result is positive, current infection should be confirmed with a qualitative HCV RNA test. In patients with confirmed HCV infection, quantitative HCV RNA testing and testing for HCV genotype is recommended. An assessment of the degree of liver fibrosis with liver biopsy or noninvasive testing is necessary to determine the urgency of treatment. Treatment of patients with chronic HCV infection should be considered based on genotype, extent of fibrosis or cirrhosis, prior treatment, comorbidities, and potential adverse effects. The goal of therapy is to reduce all-cause mortality and liver-associated complications. Although interferon-based regimens have been the mainstay of treatment for HCV infection, the U.S. Food and Drug Administration recently approved two combination-pill interferon-free treatments (ledipasvir plus sofosbuvir, and Ombitasvir/paritaprevir/ritonavir plus dasabuvir) for chronic HCV genotype 1.
ABT-450/r-ombitasvir and dasabuvir with or without ribavirin for HCV
N Engl J Med 2014 May 22;370(21):1983-92.PMID:24795200DOI:10.1056/NEJMoa1402338.
Background: The interferon-free regimen of ABT-450 with ritonavir (ABT-450/r), Ombitasvir, and dasabuvir with or without ribavirin has shown efficacy in inducing a sustained virologic response in a phase 2 study involving patients with hepatitis C virus (HCV) genotype 1 infection. We conducted two phase 3 trials to examine the efficacy and safety of this regimen in previously untreated patients with HCV genotype 1 infection and no cirrhosis. Methods: We randomly assigned 419 patients with HCV genotype 1b infection (PEARL-III study) and 305 patients with genotype 1a infection (PEARL-IV study) to 12 weeks of ABT-450/r-ombitasvir (at a once-daily dose of 150 mg of ABT-450, 100 mg of ritonavir, and 25 mg of Ombitasvir), dasabuvir (250 mg twice daily), and ribavirin administered according to body weight or to matching placebo for ribavirin. The primary efficacy end point was a sustained virologic response (an HCV RNA level of <25 IU per milliliter) 12 weeks after the end of treatment. Results: The study regimen resulted in high rates of sustained virologic response among patients with HCV genotype 1b infection (99.5% with ribavirin and 99.0% without ribavirin) and among those with genotype 1a infection (97.0% and 90.2%, respectively). Of patients with genotype 1b infection, 1 had virologic failure, and 2 did not have data available at post-treatment week 12. Among patients with genotype 1a infection, the rate of virologic failure was higher in the ribavirin-free group than in the ribavirin group (7.8% vs. 2.0%). In both studies, decreases in the hemoglobin level were significantly more common in patients receiving ribavirin. Two patients (0.3%) discontinued the study drugs owing to adverse events. The most common adverse events were fatigue, headache, and nausea. Conclusions: Twelve weeks of treatment with ABT-450/r-ombitasvir and dasabuvir without ribavirin was associated with high rates of sustained virologic response among previously untreated patients with HCV genotype 1 infection. Rates of virologic failure were higher without ribavirin than with ribavirin among patients with genotype 1a infection but not among those with genotype 1b infection.

ABT-450/r-ombitasvir and dasabuvir with ribavirin for hepatitis C with cirrhosis
N Engl J Med 2014 May 22;370(21):1973-82.PMID:24725237DOI:10.1056/NEJMoa1402869.
Background: Interferon-containing regimens for the treatment of hepatitis C virus (HCV) infection are associated with increased toxic effects in patients who also have cirrhosis. We evaluated the interferon-free combination of the protease inhibitor ABT-450 with ritonavir (ABT-450/r), the NS5A inhibitor Ombitasvir (ABT-267), the nonnucleoside polymerase inhibitor dasabuvir (ABT-333), and ribavirin in an open-label phase 3 trial involving previously untreated and previously treated adults with HCV genotype 1 infection and compensated cirrhosis. Methods: We randomly assigned 380 patients with Child-Pugh class A cirrhosis to receive either 12 or 24 weeks of treatment with ABT-450/r-ombitasvir (at a once-daily dose of 150 mg of ABT-450, 100 mg of ritonavir, and 25 mg of ombitasvir), dasabuvir (250 mg twice daily), and ribavirin administered according to body weight. The primary efficacy end point was a sustained virologic response 12 weeks after the end of treatment. The rate of sustained virologic response in each group was compared with the estimated rate with a telaprevir-based regimen (47%; 95% confidence interval [CI], 41 to 54). A noninferiority margin of 10.5 percentage points established 43% as the noninferiority threshold; the superiority threshold was 54%. Results: A total of 191 of 208 patients who received 12 weeks of treatment had a sustained virologic response at post-treatment week 12, for a rate of 91.8% (97.5% CI, 87.6 to 96.1). A total of 165 of 172 patients who received 24 weeks of treatment had a sustained virologic response at post-treatment week 12, for a rate of 95.9% (97.5% CI, 92.6 to 99.3). These rates were superior to the historical control rate. The three most common adverse events were fatigue (in 32.7% of patients in the 12-week group and 46.5% of patients in the 24-week group), headache (in 27.9% and 30.8%, respectively), and nausea (in 17.8% and 20.3%, respectively). The hemoglobin level was less than 10 g per deciliter in 7.2% and 11.0% of patients in the respective groups. Overall, 2.1% of patients discontinued treatment owing to adverse events. Conclusions: In this phase 3 trial of an oral, interferon-free regimen evaluated exclusively in patients with HCV genotype 1 infection and cirrhosis, multitargeted therapy with the use of three new antiviral agents and ribavirin resulted in high rates of sustained virologic response. Drug discontinuations due to adverse events were infrequent. (Funded by AbbVie; TURQUOISE-II ClinicalTrials.gov number, NCT01704755.).
