What is Olysio

Olysio is a protease inhibitor used for treating chronic hepatitis C virus (HCV) infections. It is a direct acting antiviral agent. Olysio reduces the activity of hepatitis C virus protease enzymes which leads to the formation of defective viruses that are unable to multiply in the liver. As a result the hepatitis C viral load decreases.

What is Olysio used for

Olysio is used for treatment of chronic hepatitis C infection in adults. It must be used in combination with peginterferon alfa and ribavirin therapy. It is effective for HCV genotype 1 infection with compensated liver disease, including cirrhosis. An alternative therapy should be considered in patients with HCV genotype 1a containing the Q80K polymorphism. HCV has more than six different genotypes. Genotype means the genetic makeup of living things. Genotyping is used to identify the different types of HCV.   

How well does Olysio work

The efficacy of Olysio was evaluated in 4 clinical studies. All subjects received 12 weeks of once daily treatment with 150 mg Olysio or placebo plus pegylated interferon alpha and ribavirin, followed by 12 or 36 weeks of therapy with peginterferon alpha and ribavirin.

  • In previously untreated subjects, hepatitis C virus levels were undetectable in 80% of Olysio treated subjects versus 50% of subjects that only received peginterferon alfa and ribavirin.

  • In previously untreated subjects with the Q80K polymorphism, hepatitis C virus levels were undetectable in 58% of Olysio treated subjects versus 52% of subjects that only received peginterferon alfa and ribavirin.

  • In subjects who failed previous therapy, virus levels were undetectable in 79% of Olysio treated subjects versus 37% of subjects that only received peginterferon alfa and ribavirin.

How is Olysio different from peginterferon alfa and ribavarin

  • Olysio is a direct acting hepatitis C virus protease inhibitor.

  • It reduces hepatitis C virus to undetectable levels in more patients.

  • It is administered for only 12 weeks.

What is the dosage of Olysio

It is supplied as Olysio 150 mg capsules. Dosing is 150 mg administered orally once daily with a meal or snack for 12 weeks in combination with peginterferon alfa and ribavirin. Peginterferon alfa and ribavirin are continued for an additional 12 or 36 weeks depending on response. It can also be combined with sofosbuvir (Sovaldi) for 12 weeks.

What are the side effects of Olysio

Common: rash, photosensitivity (sun sensitivity), pruritus, muscle pain, shortness of breath (dyspnea), and nausea.

Serious: embryofetal toxicity (due to combination with ribavarin), photosensitivity (sun sensitivity), and rash.

Antibiotics: erythromycin, clarithromycin, telithromycin

Antifungals: ketoconazole, itraconazole, posaconazole, voriconazole

Milk thistle (Silybum marianum)

HIV drugs:  elvitegravir/cobicistat/emtricitabine/tenofovir, darunavir/ritonavir, ritonavir. Combining Olysio with any HIV protease inhibitor is not recommended.
