"The hepatitis C infection treatments Viekira Pak (AbbVie) and Technivie (AbbVie) may increase the risk for serious liver injury, particularly in those with underlying advanced liver disease, the US Food and Drug Administration (FDA) warned today."...
Because OLYSIO is administered in combination with other antiviral drugs, refer to the prescribing information of the antiviral drugs used in combination with OLYSIO for a description of adverse reactions associated with their use.
The following serious and otherwise important adverse reactions are described below and in other sections of the labeling:
- Serious Symptomatic Bradycardia When Co-administered with Sofosbuvir and Amiodarone [see WARNINGS AND PRECAUTIONS and DRUG INTERACTIONS]
- Hepatic Decompensation and Hepatic Failure [see WARNINGS AND PRECAUTIONS]
- Photosensitivity [see WARNINGS AND PRECAUTIONS]
- Rash [see WARNINGS AND PRECAUTIONS]
Clinical Trials Experience
Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice.
Adverse Reactions When Used With Sofosbuvir
In the COSMOS trial, the most common (greater than 10%) adverse reactions reported during 12 weeks treatment with OLYSIO in combination with sofosbuvir (without RBV) were fatigue (25%), headache (21%), nausea (21%), insomnia (14%) and pruritus (11%). Rash and photosensitivity were reported in 11% and 7% of subjects, respectively. During 24 weeks treatment with OLYSIO in combination with sofosbuvir, dizziness (16%), and diarrhea (16%) were also commonly reported.
Adverse Reactions When Used In Combination With Peg-IFN-Alfa And RBV
The safety profile of OLYSIO in combination with Peg-IFN-alfa and RBV in patients with HCV genotype 1 infection who were treatment-na´ve or who had previously relapsed following interferon therapy with or without RBV is based on pooled data from three Phase 3 trials (QUEST-1, QUEST-2 and PROMISE) [see Clinical Studies]. These trials included a total of 1178 subjects who received OLYSIO or placebo in combination with 24 or 48 weeks of Peg-IFN-alfa and RBV. Of the 1178 subjects, 781 subjects were randomized to receive OLYSIO 150 mg once daily for 12 weeks and 397 subjects were randomized to receive placebo once daily for 12 weeks.
In the pooled Phase 3 safety data, the majority of the adverse reactions reported during 12 weeks treatment with OLYSIO in combination with Peg-IFN-alfa and RBV were Grade 1 to 2 in severity. Grade 3 or 4 adverse reactions were reported in 23% of subjects receiving OLYSIO in combination with Peg-IFN-alfa and RBV versus 25% of subjects receiving placebo in combination with Peg-IFN-alfa and RBV. Serious adverse reactions were reported in 2% of subjects receiving OLYSIO in combination with Peg-IFN-alfa and RBV and in 3% of subjects receiving placebo in combination with Peg-IFN-alfa and RBV. Discontinuation of OLYSIO or placebo due to adverse reactions occurred in 2% and 1% of subjects receiving OLYSIO with Peg-IFN-alfa and RBV and subjects receiving placebo with Peg-IFN-alfa and RBV, respectively.
The following table lists adverse reactions (all Grades) that occurred with at least 3% higher frequency among subjects with HCV genotype 1 infection receiving OLYSIO 150 mg once daily in combination with Peg-IFN-alfa and RBV, compared to subjects receiving placebo in combination with Peg-IFN-alfa and RBV, during the first 12 weeks of treatment in the pooled Phase 3 trials in subjects who were treatment-na´ve or who had previously relapsed after Peg-IFN-alfa and RBV therapy (see Table 4).

Rash And Photosensitivity
In the Phase 3 clinical trials, rash (including photosensitivity reactions) was observed in 28% of OLYSIO-treated subjects compared to 20% of placebo-treated subjects during the 12 weeks of treatment with OLYSIO or placebo in combination with Peg-IFN-alfa and RBV. Fifty-six percent (56%) of rash events in the OLYSIO group occurred in the first 4 weeks, with 42% of cases occurring in the first 2 weeks. Most of the rash events in OLYSIO-treated subjects were of mild or moderate severity (Grade 1 or Grade 2). Severe (Grade 3) rash occurred in 1% of OLYSIO-treated subjects and in none of the placebo-treated subjects. There were no reports of life-threatening (Grade 4) rash. Discontinuation of OLYSIO or placebo due to rash occurred in 1% of OLYSIO-treated subjects, compared to less than 1% of placebo-treated subjects. The frequencies of rash and photosensitivity reactions were higher in subjects with higher simeprevir exposures.
All subjects enrolled in the Phase 3 trials were directed to use sun protection measures. In these trials, adverse reactions under the specific category of photosensitivity were reported in 5% of OLYSIO-treated subjects compared to 1% of placebo-treated subjects during the 12 weeks of treatment with OLYSIO or placebo in combination with Peg-IFN-alfa and RBV. Most photosensitivity reactions in OLYSIO-treated subjects were of mild or moderate severity (Grade 1 or 2). Two OLYSIO-treated subjects experienced photosensitivity reactions which resulted in hospitalization. No life-threatening photosensitivity reactions were reported.
During the 12 weeks of treatment with OLYSIO, dyspnea was reported in 12% of OLYSIO-treated subjects compared to 8% of placebo-treated subjects (all grades; pooled Phase 3 trials). All dyspnea events reported in OLYSIO-treated subjects were of mild or moderate severity (Grade 1 or 2). There were no Grade 3 or 4 dyspnea events reported and no subjects discontinued treatment with OLYSIO due to dyspnea. Sixty-one percent (61%) of dyspnea events occurred in the first 4 weeks of treatment with OLYSIO.
There were no differences between treatment groups for the following laboratory parameters: hemoglobin, neutrophils, platelets, aspartate aminotransferase, alanine aminotransferase, amylase, or serum creatinine. Laboratory abnormalities that were observed at a higher incidence in OLYSIO-treated subjects than in placebo-treated subjects are listed in Table 5.

† No Grade 3 or 4 changes in alkaline phosphatase were observed.
‡ ULN = Upper Limit of Normal
Elevations in bilirubin were predominately mild to moderate (Grade 1 or 2) in severity, and included elevation of both direct and indirect bilirubin. Elevations in bilirubin occurred early after treatment initiation, peaking by study Week 2, and were rapidly reversible upon cessation of OLYSIO. Bilirubin elevations were generally not associated with elevations in liver transaminases. The frequency of elevated bilirubin was higher in subjects with higher simeprevir exposures.
Adverse Reactions In HCV/HIV-1 Co-infection
OLYSIO in combination with Peg-IFN-alfa and RBV was studied in 106 subjects with HCV genotype 1/HIV-1 co-infection (C212). The safety profile in HCV/HIV co-infected subjects was generally comparable to HCV mono-infected subjects.
Adverse Reactions In HCV Genotype 4 Infection
OLYSIO in combination with Peg-IFN-alfa and RBV was studied in 107 subjects with HCV genotype 4 infection (RESTORE). The safety profile of OLYSIO in subjects with HCV genotype 4 infection was comparable to subjects with HCV genotype 1 infection.
Adverse Reactions In East Asian Subjects
OLYSIO in combination with Peg-IFN-alfa and RBV was studied in a Phase 3 trial conducted in China and South Korea in treatment-na´ve subjects with chronic HCV genotype 1 infection (TIGER). The safety profile of OLYSIO in East Asian subjects was similar to that of the pooled Phase 3 population from global trials; however, a higher incidence of the laboratory abnormality hyperbilirubinemia was observed in patients receiving 150 mg OLYSIO plus Peg-IFN-alfa and RBV compared to patients receiving placebo plus Peg-IFN-alfa and RBV. Elevation of total bilirubin (all grades) was observed in 66% (99/151) of subjects treated with 150 mg OLYSIO plus Peg-IFN-alfa and RBV and in 26% (40/152) of subjects treated with placebo plus Peg-IFN-alfa and RBV. Bilirubin elevations were mainly Grade 1 or Grade 2. Grade 3 elevations in bilirubin were observed in 9% (13/151) of subjects treated with 150 mg OLYSIO plus Peg-IFN-alfa and RBV and in 1% (2/152) of subjects treated with placebo plus Peg-IFN-alfa and RBV. There were no Grade 4 elevations in bilirubin. The bilirubin elevations were not associated with increases in liver transaminases and were reversible after the end of treatment [see Use In Specific Populations and Clinical Studies].
The following adverse reactions have been reported during post approval use of OLYSIO. Because postmarketing reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish a causal relationship between drug exposure and these adverse reactions.
Serious symptomatic bradycardia has been reported in patients taking amiodarone who initiate treatment with sofosbuvir in combination with another HCV direct-acting antiviral, including OLYSIO [see WARNINGS AND PRECAUTIONS and DRUG INTERACTIONS].
hepatic decompensation, hepatic failure [see WARNINGS AND PRECAUTIONS].

Potential For OLYSIO To Affect Other Drugs
Simeprevir mildly inhibits CYP1A2 activity and intestinal CYP3A4 activity, but does not affect hepatic CYP3A4 activity. Co-administration of OLYSIO with drugs that are primarily metabolized by CYP3A4 may result in increased plasma concentrations of such drugs (see Table 6).
Simeprevir inhibits OATP1B1/3 and P-glycoprotein (P-gp) transporters. Co-administration of OLYSIO with drugs that are substrates for OATP1B1/3 and P-gp transport may result in increased plasma concentrations of such drugs (see Table 6).
Potential For Other Drugs To Affect OLYSIO
The primary enzyme involved in the biotransformation of simeprevir is CYP3A [see CLINICAL PHARMACOLOGY]. Clinically relevant effects of other drugs on simeprevir pharmacokinetics via CYP3A may occur. Co-administration of OLYSIO with moderate or strong inhibitors of CYP3A may significantly increase the plasma exposure of simeprevir. Co-administration with moderate or strong inducers of CYP3A may significantly reduce the plasma exposure of simeprevir and lead to loss of efficacy (see Table 6). Therefore, co-administration of OLYSIO with substances that are moderate or strong inducers or inhibitors of CYP3A is not recommended [see WARNINGS AND PRECAUTIONS and CLINICAL PHARMACOLOGY].
Established And Other Potentially Significant Drug Interactions
Table 6 shows the established and other potentially significant drug interactions based on which alterations in dose or regimen of OLYSIO and/or co-administered drug may be recommended. Drugs that are not recommended for co-administration with OLYSIO are also included in Table 6. For information regarding the magnitude of interaction, see Tables 7 and 8 [see CLINICAL PHARMACOLOGY].
