Testing Prior to Initiation of Therapy

Q80K Testing in HCV Genotype 1a-Infected Patients

OLYSIO in Combination with Sofosbuvir

In HCV genotype 1a-infected patients with compensated cirrhosis, screening for the presence of virus with the NS3 Q80K polymorphism may be considered prior to initiation of treatment with OLYSIO with sofosbuvir [see Clinical Studies (14.2)].

OLYSIO in Combination with Peg-IFN-alfa and RBV

Prior to initiation of treatment with OLYSIO in combination with Peg-IFN-alfa and RBV, screening patients with HCV genotype 1a infection for the presence of virus with the NS3 Q80K polymorphism is strongly recommended and alternative therapy should be considered for patients infected with HCV genotype 1a containing the Q80K polymorphism [see Indications and Usage (1) and Microbiology (12.4)].

Hepatic Laboratory Testing

Monitor liver chemistry tests before and during OLYSIO combination therapy [see Warnings and Precautions (5.2)].

OLYSIO Combination Treatment

Administer OLYSIO in combination with other antiviral drugs for the treatment of chronic HCV infection. OLYSIO monotherapy is not recommended. The recommended dosage of OLYSIO is one 150 mg capsule taken orally once daily with food [see Clinical Pharmacology (12.3)]. The capsule should be swallowed as a whole. For specific dosing recommendations for the antiviral drugs used in combination with OLYSIO, refer to their respective prescribing information.

OLYSIO can be taken in combination with sofosbuvir or in combination with Peg-IFN-alfa and RBV.

OLYSIO in Combination with Sofosbuvir

Table 1 displays the recommended treatment regimen and duration of OLYSIO in combination with sofosbuvir in patients with chronic HCV genotype 1 infection.

Table 1: Recommended Treatment Regimen and Duration for OLYSIO and Sofosbuvir Combination Therapy in Patients with Chronic HCV Genotype 1 Infection
Patient Population (HCV Genotype 1) Treatment Regimen and Duration
*
Treatment-experienced patients include prior relapsers, prior partial responders and prior null responders who failed prior IFN-based therapy [see Clinical Studies (14)].
Treatment-naïve and treatment-experienced* patients:
  without cirrhosis 12 weeks of OLYSIO + sofosbuvir
  with compensated cirrhosis (Child-Pugh A) 24 weeks of OLYSIO + sofosbuvir

OLYSIO in Combination with Peg-IFN-alfa and RBV

Table 2 displays the recommended treatment regimen and duration of OLYSIO in combination with Peg-IFN-alfa and RBV in mono-infected and HCV/HIV-1 co-infected patients with HCV genotype 1 or 4 infection. Refer to Table 3 for treatment stopping rules for OLYSIO combination therapy with Peg-IFN-alfa and RBV.

Table 2: Recommended Treatment Regimen and Duration for OLYSIO, Peg-IFN-alfa, and RBV Combination Therapy in Patients with Chronic HCV Genotype 1 or 4 Infection
Patient Population (HCV Genotype 1 or 4) Treatment Regimen and Duration
HIV = human immunodeficiency virus.
*
Prior relapser: HCV RNA not detected at the end of prior IFN-based therapy and HCV RNA detected during follow-up [see Clinical Studies (14)].
Recommended duration of treatment if patient does not meet stopping rules (see Table 3).
Prior partial responder: prior on-treatment ≥ 2 log10 IU/mL reduction in HCV RNA from baseline at Week 12 and HCV RNA detected at end of prior IFN-based therapy [see Clinical Studies (14)].
§
Prior null responder: prior on-treatment < 2 log10 IU/mL reduction in HCV RNA from baseline at Week 12 during prior IFN-based therapy [see Clinical Studies (14)].
Treatment-naïve patients and prior relapsers*:
  HCV mono-infected patients without cirrhosis or with compensated cirrhosis (Child-Pugh A) 12 weeks of OLYSIO + Peg-IFN-alfa + RBV followed by additional 12 weeks of Peg-IFN-alfa + RBV (total treatment duration of 24 weeks)
  HCV/HIV-1 co-infected patients without cirrhosis  
  HCV/HIV-1 co-infected patients with compensated cirrhosis (Child-Pugh A) 12 weeks of OLYSIO + Peg-IFN-alfa + RBV followed by additional 36 weeks of Peg-IFN-alfa + RBV (total treatment duration of 48 weeks)
Prior non-responders (including partial and null responders§):
  HCV/HIV-1 co-infected or HCV mono-infected patients without cirrhosis or with compensated cirrhosis (Child-Pugh A) 12 weeks of OLYSIO + Peg-IFN-alfa + RBV followed by additional 36 weeks of Peg-IFN-alfa + RBV (total treatment duration of 48 weeks)

Discontinuation of Dosing

OLYSIO in Combination with Sofosbuvir

No treatment stopping rules apply to the combination of OLYSIO with sofosbuvir [see Clinical Studies (14.2)].

OLYSIO in Combination with Peg-IFN-alfa and RBV

During treatment, HCV RNA levels should be monitored as clinically indicated using a sensitive assay with a lower limit of quantification of at least 25 IU/mL. Because patients with an inadequate on-treatment virologic response (i.e., HCV RNA greater or equal to 25 IU/mL) are not likely to achieve a sustained virologic response (SVR), discontinuation of treatment is recommended in these patients. Table 3 presents treatment stopping rules for patients who experience an inadequate on-treatment virologic response at Weeks 4, 12, and 24.

Table 3: Treatment Stopping Rules in Patients Receiving OLYSIO in Combination with Peg-IFN-alfa and RBV with Inadequate On-Treatment Virologic Response
Treatment Week HCV RNA Action
Week 4 ≥ 25 IU/mL Discontinue OLYSIO, Peg-IFN-alfa, and RBV
Week 12 Discontinue Peg-IFN-alfa, and RBV (treatment with OLYSIO is complete at Week 12)  
Week 24 Discontinue Peg-IFN-alfa, and RBV (treatment with OLYSIO is complete at Week 12)  

Dosage Adjustment or Interruption

To prevent treatment failure, avoid reducing the dosage of OLYSIO or interrupting treatment. If treatment with OLYSIO is discontinued because of adverse reactions or inadequate on-treatment virologic response, OLYSIO treatment must not be reinitiated [see Warnings and Precautions (5.2)].

If adverse reactions potentially related to the antiviral drug(s) used in combination with OLYSIO occur, refer to the instructions outlined in their respective prescribing information for recommendations on dosage adjustment or interruption.

If any of the other antiviral drug(s) used in combination with OLYSIO for the treatment of chronic HCV infection are permanently discontinued for any reason, OLYSIO should also be discontinued.

Not Recommended in Patients with Moderate or Severe Hepatic Impairment

OLYSIO is not recommended for patients with moderate or severe hepatic impairment (Child-Pugh Class B or C) [see Warnings and Precautions (5.2), Adverse Reactions (6.1), Use in Specific Populations (8.8), and Clinical Pharmacology (12.3)].
