Overview

Simeprevir is a hepatitis C virus NS3/4A protease inhibitor that is FDA approved for the treatment of chronic hepatitis C (CHC) genotype 1 infection as a component of a combination antiviral treatment regimen. Common adverse reactions include pruritus, rash, nausea, hyperbilirubinemia, headache, insomnia, and fatigue.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

Indications

Simeprevir is a hepatitis C virus (HCV) NS3/4A protease inhibitor indicated for the treatment of chronic hepatitis C (CHC) genotype 1 infection as a component of a combination antiviral treatment regimen.

Limitations of Use:

• Simeprevir mono therapy is not recommended.

• Simeprevir efficacy in combination with peg interferon alfa and ribavirin (RBV) is substantially reduced in patients infected with HCV genotype 1a with an NS3 Q80K polymorphism at baseline compared to patients infected with hepatitis C virus (HCV) genotype 1a without the Q80K polymorphism. Screening patients with HCV genotype 1a infection for the presence of virus with the NS3 Q80K polymorphism at baseline is strongly recommended. Alternative therapy should be considered for patients infected with HCV genotype 1a containing the Q80K polymorphism.
• Simeprevir is not recommended in patients with severe hepatic impairment (Child-Pugh Class C) due to substantial increases in simeprevir exposures, which have been associated with increased frequency of adverse reactions.
• Simeprevir is not recommended in patients who have previously failed therapy with a treatment regimen that included simeprevir or other HCV protease inhibitors.

Dosage

Simeprevir Combination Treatment

Administer simeprevir in combination with other antiviral drugs for the treatment of CHC infection. For specific dosing recommendations for the antiviral drugs used in combination with simeprevir, refer to their respective prescribing information. Simeprevir monotherapy is not recommended. Administer simeprevir in combination with either:

• Peg-IFN-alfa and RBV: Table 1 displays the recommended dosage regimen and treatment duration of simeprevir in combination with Peg-IFN-alfa and RBV. Refer to Table 3 for treatment stopping rules for simeprevir combination therapy with Peg-IFN-alfa and RBV; or
• Sofosbuvir: Table 2 displays the recommended dosage regimen and treatment duration of simeprevir in combination with sofosbuvir.

The recommended dosage of simeprevir is one capsule taken orally once daily with food. The capsule should be swallowed as a whole.

Testing Prior to Initiation of simeprevir in HCV Genotype 1a-Infected Patients

Prior to initiation of treatment with simeprevir 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. Prior to initiation of treatment with simeprevir with sofosbuvir, screening patients infected with HCV genotype 1a for the presence of virus with the NS3 Q80K polymorphism is not strongly recommended but may be considered.

Discontinuation of Dosing

Use 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 ≥ 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 virology response at Weeks 4, 12, and 24.

Dosage Adjustment or Interruption

To prevent treatment failure, avoid reducing the dosage of simeprevir or interrupting treatment. If treatment with simeprevir is discontinued because of adverse reactions or inadequate on-treatment virologic response, simeprevir treatment must not be reinitiated.

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

If any of the other antiviral drugs used in combination with simeprevir for the treatment of CHC infection are permanently discontinued for any reason, simeprevir should also be discontinued.

Hepatic Impairment

No dosage recommendation can be made for patients with moderate hepatic impairment (Child-Pugh Class B) due to modest increases in simeprevir exposures. Simeprevir is not recommended for patients with severe hepatic impairment (Child-Pugh Class C) due to substantially higher simeprevir exposures. In clinical trials, higher simeprevir exposures have been associated with increased frequency of adverse reactions, including rash and photosensitivity.

The safety and efficacy of simeprevir have not been studied in HCV-infected patients with moderate or severe hepatic impairment (Child-Pugh Class B or C). Do not administer simeprevir in combination with Peg-IFN-alfa and RBV in patients with decompensated cirrhosis (moderate or severe hepatic impairment) [see Peg-IFN-alfa prescribing information]. The potential risks and benefits of simeprevir should be carefully considered prior to use in patients with moderate hepatic impairment.

Contraindications

There are no specific contraindications to simeprevir. However, as simeprevir should always be administered in combination with other antiviral drugs for the treatment of chronic hepatitis C infection, prescribers should consult the complete prescribing information for these drugs for a description of contraindications.

Warnings

Risk of Serious Adverse Reactions Associated With Combination Treatment

Simeprevir should be used in combination with other antiviral drugs for the treatment of CHC infection. Therefore, consult the prescribing information for these drugs before starting therapy with simeprevir. Warnings and Precautions related to these drugs also apply to their use in simeprevir combination treatment.

Photosensitivity

Photosensitivity reactions have been observed with simeprevir combination therapy. Serious photosensitivity reactions resulting in hospitalization have been observed with simeprevir in combination with Peg-IFN-alfa and ribavirin. Photosensitivity reactions occurred most frequently in the first 4 weeks of treatment, but can occur at any time during treatment. Photosensitivity may present as an exaggerated sunburn reaction, usually affecting areas exposed to light (typically the face, "V" area of the neck, extensor surfaces of the forearms, and dorsa of the hands). Manifestations may include burning, erythema, exudation, blistering, and edema.

Use sun protective measures and limit sun exposure during treatment with simeprevir. Avoid use of tanning devices during treatment with simeprevir. Discontinuation of simeprevir should be considered if a photosensitivity reaction occurs and patients should be monitored until the reaction has resolved. If a decision is made to continue simeprevir in the setting of a photosensitivity reaction, expert consultation is advised.

Rash

Rash has been observed with simeprevir combination therapy. Rash occurred most frequently in the first 4 weeks of treatment, but can occur at any time during treatment. Severe rash and rash requiring discontinuation of simeprevir have been reported in subjects receiving simeprevir in combination with Peg-IFN-alfa and RBV. Most of the rash events in OLYSIO-treated patients were of mild or moderate severity. Patients with mild to moderate rashes should be followed for possible progression of rash, including the development of mucosal signs (e.g., oral lesions, conjunctivitis) or systemic symptoms. If the rash becomes severe, simeprevir should be discontinued. Patients should be monitored until the rash has resolved.

Sulfa Allergy

OLYSIO contains a sulfonamide moiety. In subjects with a history of sulfa allergy (n=16), no increased incidence of rash or photosensitivity reactions has been observed. However, there are insufficient data to exclude an association between sulfa allergy and the frequency or severity of adverse reactions observed with the use of simeprevir.

Risk of Adverse Reactions or Reduced Therapeutic Effect Due to Drug Interactions

Co-administration of simeprevir with substances that are moderate or strong inducers or inhibitors of cytochrome P450 3A (CYP3A) is not recommended as this may lead to significantly lower or higher exposure of simeprevir, respectively, which may result in reduced therapeutic effect or adverse reactions

Adverse Reactions

Clinical Trials Experience

OLYSIO should be administered in combination with other antiviral drugs. Refer to the prescribing information of the antiviral drugs used in combination with simeprevir for a description of adverse reactions associated with their use.

The following serious and otherwise important adverse drug reactions (ADRs) are discussed in detail in another section of the labeling:

• Photosensitivity
• Rash

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 in Combination with Peg-IFN-Alfa and RBV

The safety profile of simeprevir in combination with Peg-IFN-alfa and RBV in patients with HCV genotype 1 infection who were treatment-naïve or who had previously relapsed following interferon therapy with or without RBV is based on pooled data from three Phase 3 trials [see CLINICAL STUDIES (14)]. These trials included a total of 1178 subjects who received simeprevir 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 simeprevir 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 simeprevir 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 simeprevir 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 simeprevir 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 simeprevir or placebo due to adverse reactions occurred in 2% and 1% of subjects receiving simeprevir 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 receiving simeprevir 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-naïve 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 simeprevir or placebo in combination with Peg-IFN-alfa and RBV. Fifty-six percent (56%) of rash events in the simeprevir 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 simeprevir 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 simeprevir 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.

Dyspnea

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 simeprevir due to dyspnea. Sixty-one percent (61%) of dyspnea events occurred in the first 4 weeks of treatment with simeprevir.

Laboratory abnormalities

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.

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 simeprevir. Bilirubin elevations were generally not associated with elevations in liver transaminases.

Adverse Reactions when Used with Sofosbuvir

In the COSMOS trial, the most common (> 10%) adverse reactions reported during 12 weeks treatment with simeprevir 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 simeprevir in combination with sofosbuvir, dizziness (16%), and diarrhea (16%) were also commonly reported.

Postmarketing Experience

There is limited information regarding Simeprevir Postmarketing Experience in the drug label.

Drug Interactions

Potential for simeprevir to Affect Other Drugs

Simeprevir mildly inhibits CYP1A2 activity and intestinal CYP3A4 activity, but does not affect hepatic CYP3A4 activity. Co-administration of simeprevir with drugs that are primarily metabolized by CYP3A4 may result in increased plasma concentrations of such drugs (see TABLE 6). Simeprevir does not affect CYP2C9, CYP2C19 or CYP2D6 in vivo.

Simeprevir inhibits OATP1B1/3 and P-glycoprotein (P-gp) transporters. Co-administration of simeprevir 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. Clinically relevant effects of other drugs on simeprevir pharmacokinetics via CYP3A may occur. Co-administration of simeprevir 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 simeprevir with substances that are moderate or strong inducers or inhibitors of CYP3A is not recommended.

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 simeprevir and/or co-administered drug may be recommended. Drugs that are not recommended for co-administration with simeprevir are also included in Table 6. For information regarding the magnitude of interaction, see TABLES 7 and 8.

This image is provided by the National Library of Medicine.

Drugs without Clinically Significant Interactions with OLYSIO

In addition to the drugs included in Table 6, the interaction between simeprevir and the following drugs were evaluated in clinical studies and no dose adjustments are needed for either drug caffeine, dextromethorphan, escitalopram, ethinyl estradiol/norethindrone, methadone, midazolam (intravenous administration), omeprazole, raltegravir, rilpivirine, sofosbuvir, tacrolimus, tenofovir, disoproxil fumarate, and warfarin.

No clinically relevant drug-drug interaction is expected when simeprevir is co-administered with antacids, the corticosteroids budesonide, fluticasone, methylprednisolone, and prednisone, fluvastatin, H2-receptor antagonists, the narcotic analgesics buprenorphine and naloxone, NRTIs (such as abacavir, didanosine, emtricitabine, lamivudine, stavudine, zidovudine), maraviroc, methylphenidate, and proton pump inhibitors.

Use in Specific Populations

Pregnancy

Pregnancy Category (FDA): C

Pregnancy

OLYSIO must be administered in combination with other antiviral drugs. Refer to prescribing information of the drugs used in combination with simeprevir for information regarding use in pregnancy.

Pregnancy Category C

Risk Summary

Adequate and well-controlled trials with simeprevir have not been conducted in pregnant women. In animal reproduction studies with simeprevir, embryofetal developmental toxicity was observed at drug exposures higher than human exposure at the recommended clinical dose. Simeprevir should be used during pregnancy only if the potential benefit justifies the potential risk. Female patients of childbearing potential should use an effective contraceptive method.

If simeprevir is administered with Peg-IFN-alfa and RBV, refer to the prescribing information for Peg-IFN-alfa and RBV for information on use in pregnancy.

Animal Data

Simeprevir showed no teratogenicity in rats and mice at exposures 0.5 times (in rats) and 6 times (in mice) the mean area under the plasma concentration time curve (AUC) in humans at the recommended dose of 150 mg once daily.

In a mouse embryofetal study at doses up to 1000 mg/kg, simeprevir resulted in early and late in utero fetal losses and early maternal deaths at an exposure approximately 6 times higher than the mean AUC in humans at the recommended 150 mg daily dose. Significantly decreased fetal weights and an increase in fetal skeletal variations were seen at exposures approximately 4 times higher than the mean AUC in humans at the recommended daily dose.

In a rat pre- and postnatal study, maternal animals were exposed to simeprevir during gestation and lactation at doses up to 1000 mg/kg/day. In pregnant rats, simeprevir resulted in early deaths at 1000 mg/kg/day corresponding to exposures similar to the mean AUC in humans at the recommended 150 mg once daily dose. Significant reduction in body weight gain was seen at an exposure 0.7 times the mean AUC in humans at the recommended 150 mg once daily dose. The developing rat offspring exhibited significantly decreased body weight and negative effects on physical growth (delay and small size) and development (decreased motor activity) following simeprevir exposure in utero (via maternal dosing) and during lactation (via maternal milk to nursing pups) at a maternal exposure similar to the mean AUC in humans at the recommended 150 mg once daily dose. Subsequent survival, behavior and reproductive capacity were not affected.
Pregnancy Category (AUS): There is no Australian Drug Evaluation Committee (ADEC) guidance on usage of Simeprevir in women who are pregnant.

Labor and Delivery

There is no FDA guidance on use of Simeprevir during labor and delivery.

Nursing Mothers

Nursing Mothers

It is not known whether simeprevir or its metabolites are present in human breast milk. When administered to lactating rats, simeprevir was detected in plasma of suckling rats likely due to excretion of simeprevir via milk. Because of the potential for adverse reactions from the drug in nursing infants, a decision must be made whether to discontinue nursing or discontinue treatment with OLYSIO, taking into account the importance of the therapy to the mother.

If simeprevir is administered in a regimen containing RBV, the information for RBV with regard to nursing mothers also applies to this combination regimen.

Pediatric Use

The safety and efficacy of simeprevir in pediatric patients have not been established.

Geriatic Use

Clinical studies of simeprevir did not include sufficient numbers of patients older than 65 years to determine whether they respond differently from younger patients. No dose adjustment of simeprevir is required in geriatric patients.

Gender

There is no FDA guidance on the use of Simeprevir with respect to specific gender populations.

Race

Patients of East Asian ancestry exhibit higher simeprevir exposures. In clinical trials, higher simeprevir exposures have been associated with increased frequency of adverse reactions, including rash and photosensitivity. There are insufficient safety data to recommend an appropriate dose for patients of East Asian ancestry. The potential risks and benefits of simeprevir should be carefully considered prior to use in patients of East Asian ancestry.

Renal Impairment

No dose adjustment of simeprevir is required in patients with mild, moderate or severe renal impairment. The safety and efficacy of simeprevir have not been studied in HCV-infected patients with severe renal impairment (creatinine clearance below 30 mL/min) or end-stage renal disease, including patients requiring dialysis. Simeprevir is highly protein-bound; therefore, dialysis is unlikely to result in significant removal of simeprevir.

Refer to the prescribing information for the other antiviral drug(s) used in combination with simeprevir regarding their use in patients with renal impairment.

Hepatic Impairment

No dose adjustment of simeprevir is required in patients with mild hepatic impairment (Child-Pugh Class A). The safety and efficacy of simeprevir have not been studied in HCV-infected patients with moderate or severe hepatic impairment (Child-Pugh Class B or C). No dosage recommendation can be given for patients with moderate hepatic impairment (Child-Pugh Class B) due to modest increases in simeprevir exposures. Simeprevir is not recommended for patients with severe hepatic impairment (Child-Pugh Class C) due to substantially higher simeprevir exposures.

In clinical trials, higher simeprevir exposures have been associated with increased frequency of adverse reactions, including rash and photosensitivity. The potential risks and benefits of simeprevir should be carefully considered prior to use in patients with moderate hepatic impairment.

Refer to the prescribing information for the antiviral drug(s) used in combination with simeprevir regarding their use in patients with hepatic impairment. The combination of simeprevir with Peg-IFN-alfa and RBV is contraindicated in patients with decompensated cirrhosis (moderate or severe hepatic impairment).

Females of Reproductive Potential and Males

There is no FDA guidance on the use of Simeprevir in women of reproductive potentials and males.

Immunocompromised Patients

There is no FDA guidance one the use of Simeprevir in patients who are immunocompromised.

Administration and Monitoring

Administration

Oral

Monitoring

• 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 virology response (i.e., HCV RNA ≥ 25 IU/mL) are not likely to achieve a sustained virology response (SVR), discontinuation of treatment is recommended in these patients.

• Discontinuation of simeprevir should be considered if a photosensitivity reaction occurs and patients should be monitored until the reaction has resolved. If a decision is made to continue simeprevir in the setting of a photosensitivity reaction, expert consultation is advised.

• Discontinuation of simeprevir should be considered if the rash becomes severePatients should be monitored until the rash has resolved.

• Concomitant use of simeprevir with digoxin resulted in increased concentrations of digoxin due to inhibition of P-gp by simeprevir. Routine therapeutic drug monitoring of digoxin concentrations is acceptable.

• Concomitant use of simeprevir with these antiarrhythmics when given orally may result in mild increases in concentrations of these antiarrhythmics due to intestinal CYP3A4 inhibition by simeprevir. Therapeutic drug monitoring for these antiarrhythmics, if available, is recommended when co-administered with simeprevir.

• Clinical monitoring of patients is recommended when simeprevir is co-administered with orally administered calcium channel blockers.

• Concomitant use of simeprevir with simvastatin resulted in increased plasma concentrations of simvastatin. Titrate the simvastatin dose carefully and use the lowest necessary dose of simvastatin while monitoring for safety when co-administered with simeprevir.

• Concomitant use of simeprevir with pitavastatin, pravastatin or lovastatin has not been studied. The dose of pitavastatin, pravastatin or lovastatin should be titrated carefully and the lowest necessary dose should be used while monitoring for safety when co-administered with simeprevir.

• Concomitant use of simeprevir and sirolimus may result in mildly increased or decreased plasma concentrations of sirolimus. Routine monitoring of blood concentrations of sirolimus is acceptable.

• Dose adjustment of the PDE-5 inhibitor may be required when simeprevir is co-administered with sildenafil or tadalafil administered chronically at doses used for the treatment of pulmonary arterial hypertension. Consider starting with the lowest dose of the PDE-5 inhibitor and increase as needed, with clinical monitoring as appropriate.

IV Compatibility

There is limited information regarding the compatibility of Simeprevir and IV administrations.

Overdosage

Human experience of overdose with simeprevir is limited. There is no specific antidote for overdose with simeprevir. In the event of an overdose, the patient's clinical status should be observed and the usual supportive measures employed.

Simeprevir is highly protein-bound; therefore, dialysis is unlikely to result in significant removal of simeprevir.

Pharmacology

Mechanism of Action

Simeprevir is a direct-acting antiviral (DAA) agent against the hepatitis C virus.

Structure

OLYSIO (simeprevir) is an inhibitor of the HCV NS3/4A protease.

The chemical name for simeprevir is (2R,3aR,10Z,11aS,12aR,14aR)-N-(cyclopropylsulfonyl)-2-2-(4-isopropyl-1,3-thiazol-2-yl)-7-methoxy-8-methyl-4-quinolinyl]oxy]-5-methyl-4,14-dioxo-2,3,3a,4,5,6,7,8,9,11a,12,13,14,14a-tetradecahydrocyclopenta[c]cyclopropa[g][1,6]diazacyclotetradecine-12a(1H)-carboxamide. Its molecular formula is C38H47N5O7S2 and its molecular weight is 749.94. Simeprevir has the following structural formula:

File:Simeprevir.TA.png

Chemical Structure

Simeprevir drug substance is a white to almost white powder. Simeprevir is practically insoluble in water over a wide pH range. It is practically insoluble in propylene glycol, very slightly soluble in ethanol, and slightly soluble in acetone. It is soluble in dichloromethane and freely soluble in some organic solvents (e.g., tetrahydrofuran and N,N-dimethylformamide).

OLYSIO (simeprevir) for oral administration is available as 150 mg strength hard gelatin capsules. Each capsule contains 154.4 mg of simeprevir sodium salt, which is equivalent to 150 mg of simeprevir. OLYSIO (simeprevir) capsules contain the following inactive ingredients: colloidal anhydrous silica, croscarmellose sodium, lactose monohydrate, magnesium stearate and sodium lauryl sulphate. The white capsule contains gelatin and titanium dioxide (E171) and is printed with ink containing iron oxide black (E172) and shellac (E904).

Pharmacodynamics

Cardiac Electrophysiology

The effect of simeprevir at the recommended dose of 150 mg once daily and 350 mg (at 2.3 times the recommended dosage) once daily for 7 days on the QT interval was evaluated in a randomized, double-blind, placebo- and positive-controlled (moxifloxacin 400 mg once daily), 4-way cross-over study in 60 healthy subjects. No meaningful changes in QTc interval were observed at either the recommended dose of 150 mg once daily or the dose of 350 mg (2.3 times the recommended dosage) once daily.

Pharmacokinetics

The pharmacokinetic properties of simeprevir have been evaluated in healthy adult subjects and in adult HCV-infected subjects. Plasma Cmax and AUC increased more than dose-proportionally after multiple doses between 75 mg and 200 mg once daily, with accumulation occurring following repeated dosing. Steady-state was reached after 7 days of once daily dosing. Plasma exposure (AUC) of simeprevir in HCV-infected subjects was about 2- to 3-fold higher compared to that observed in HCV-uninfected subjects. Plasma Cmax and AUC of simeprevir were similar during co-administration of simeprevir with Peg-IFN-alfa and RBV compared with administration of simeprevir alone. In HCV-infected subjects, the mean steady-state predose plasma concentration was 1936 ng/mL (standard deviation: 2640) and the mean steady-state AUC24 was 57469 ng.h/mL (standard deviation: 63571).

Absorption

Simeprevir is orally bioavailable. Maximum plasma concentrations (Cmax) are typically achieved between 4 to 6 hours post dose.

In vitro studies with human Caco-2 cells indicated that simeprevir is a substrate of P-gp.

Effects of Food on Oral Absorption

Administration of simeprevir with food to healthy subjects increased the relative bioavailability (AUC) by 61% and 69% after a high-fat, high-caloric (928 kcal) and normal-caloric (533 kcal) breakfast, respectively, and delayed the absorption by 1 hour and 1.5 hours, respectively. Due to increased bioavailability, simeprevir should be administered with food. The type of food does not affect exposure to simeprevir.

Distribution

Simeprevir is extensively bound to plasma proteins (greater than 99.9%), primarily to albumin and, to a lesser extent, alfa 1-acid glycoprotein. Plasma protein binding is not meaningfully altered in patients with renal or hepatic impairment.

In animals, simeprevir is extensively distributed to gut and liver (liver:blood ratio of 29:1 in rat) tissues. In vitro data and physiologically-based pharmacokinetic modeling and simulations indicate that hepatic uptake in humans is mediated by OATP1B1/3.

Metabolism

Simeprevir is metabolized in the liver. In vitro experiments with human liver microsomes indicated that simeprevir primarily undergoes oxidative metabolism by the hepatic CYP3A system. Involvement of CYP2C8 and CYP2C19 cannot be excluded. Co-administration of simeprevir with moderate or strong inhibitors of CYP3A may significantly increase the plasma exposure of simeprevir, and co-administration with moderate or strong inducers of CYP3A may significantly reduce the plasma exposure of simeprevir [see DRUG INTERACTIONS (7)].

Following a single oral administration of 200 mg (1.3 times the recommended dosage) 14C-simeprevir to healthy subjects, the majority of the radioactivity in plasma (mean: 83%) was accounted for by unchanged drug and a small part of the radioactivity in plasma was related to metabolites (none being major metabolites). Metabolites identified in feces were formed via oxidation at the macrocyclic moiety or aromatic moiety or both and by O-demethylation followed by oxidation.

Elimination

Elimination of simeprevir occurs via biliary excretion. Renal clearance plays an insignificant role in its elimination. Following a single oral administration of 200 mg 14C-simeprevir to healthy subjects, on average 91% of the total radioactivity was recovered in feces. Less than 1% of the administered dose was recovered in urine. Unchanged simeprevir in feces accounted for on average 31% of the administered dose.

The terminal elimination half-life of simeprevir was 10 to 13 hours in HCV-uninfected subjects and 41 hours in HCV-infected subjects receiving 200 mg (1.3 times the recommended dosage) of simeprevir.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis and Mutagenesis

Simeprevir was not genotoxic in a series of in vitro and in vivo tests including the Ames test, the mammalian forward mutation assay in mouse lymphoma cells or the in vivo mammalian micronucleus test. Carcinogenicity studies with simeprevir have not been conducted.

If OLYSIO is administered in a combination regimen containing RBV, refer to the prescribing information for RBV for information on carcinogenesis and mutagenesis.

Impairment of Fertility

In a rat fertility study at doses up to 500 mg/kg/day, 3 male rats treated with simeprevir (2/24 rats at 50 mg/kg/day and 1/24 rats at 500 mg/kg/day) showed no motile sperm, small testes and epididymides, and resulted in infertility in 2 out of 3 of the male rats at approximately 0.2 times the mean AUC in humans.

If OLYSIO is administered with Peg-IFN-alfa and RBV, refer to the prescribing information for Peg-IFN-alfa and RBV for information on impairment of fertility.

Animal Toxicology and/or Pharmacology

Cardiovascular toxicity consisting of acute endocardial and myocardial necrosis restricted to the left ventricular subendocardial area was seen in 2 out of 6 animals in a 2-week oral dog toxicity study at an exposure approximately 28 times the mean AUC in humans at the recommended daily dose of 150 mg. No cardiac findings were observed in a 6-month and a 9-month oral toxicity study at exposures, respectively, of 11 and 4 times the mean AUC in humans at the recommended daily dose of 150 mg.

If OLYSIO is administered in a combination regimen containing sofosbuvir, refer to the prescribing information for sofosbuvir for information on animal toxicology.

Clinical Studies

Overview of Clinical Trials

The efficacy of OLYSIO in combination with Peg-IFN-alfa and RBV in patients with HCV genotype 1 infection was evaluated in two Phase 3 trials in treatment-naïve subjects (trials QUEST 1 and QUEST 2), one Phase 3 trial in subjects who relapsed after prior interferon-based therapy (PROMISE) and one Phase 2 trial in subjects who failed prior therapy with Peg-IFN and RBV (including prior relapsers, partial and null responders) (ASPIRE). Prior relapsers were subjects who had HCV RNA not detected at the end of prior IFN-based therapy and HCV RNA detected during follow-up; prior partial responders were subjects with prior on-treatment greater than or equal to 2 log10 reduction in HCV RNA from baseline at Week 12 and HCV RNA detected at the end of prior therapy with Peg-IFN and RBV; and null responders were subjects with prior on-treatment less than 2 log10 reduction in HCV RNA from baseline at Week 12 during prior therapy with Peg-IFN and RBV. Subjects in these trials had compensated liver disease (including cirrhosis), HCV RNA of at least 10000 IU/mL, and liver histopathology consistent with CHC infection. In subjects who were treatment-naïve and prior relapsers, the overall duration of treatment with Peg-IFN-alfa and RBV in the Phase 3 trials was response-guided. In these subjects, the planned total duration of HCV treatment was 24 weeks if the following on-treatment protocol-defined response-guided therapy (RGT) criteria were met: HCV RNA lower than 25 IU/mL (detected or not detected) at Week 4 AND HCV RNA not detected at Week 12. Plasma HCV RNA levels were measured using the Roche COBAS® TaqMan® HCV test (version 2.0), for use with the High Pure System (25 IU/mL lower limit of quantification and 15 IU/mL limit of detection). Treatment stopping rules for HCV therapy were used to ensure that subjects with inadequate on-treatment virologic response discontinued treatment in a timely manner.

The efficacy of OLYSIO in combination with sofosbuvir without or with RBV was evaluated in a Phase 2 trial (COSMOS) in HCV genotype 1 infected prior null responders with METAVIR fibrosis score F0–F4 or treatment-naïve subjects with METAVIR fibrosis score F3–F4 and compensated liver disease.

SVR was defined as HCV RNA not detected 24 weeks after planned end of treatment (SVR24) in the ASPIRE trial and was defined as HCV RNA lower than 25 IU/mL detected or not detected 12 weeks after the planned end of treatment (SVR12) in the COSMOS and Phase 3 trials.

Treatment with OLYSIO in Combination with Peg-IFN-alfa and RBV

Treatment-Naïve Adult Subjects with HCV Genotype 1 Infection

The efficacy of OLYSIO in treatment-naïve patients with HCV genotype 1 infection was demonstrated in two randomized, double-blind, placebo-controlled, 2-arm, multicenter, Phase 3 trials (QUEST 1 and QUEST 2). The designs of both trials were similar. All subjects received 12 weeks of once daily treatment with 150 mg OLYSIO or placebo, plus Peg-IFN-alfa-2a (QUEST 1 and QUEST 2) or Peg-IFN-alfa-2b (QUEST 2) and RBV, followed by 12 or 36 weeks of therapy with Peg-IFN-alfa and RBV in accordance with the on-treatment protocol-defined RGT criteria. Subjects in the control groups received 48 weeks of Peg-IFN-alfa-2a or -2b and RBV.

In the pooled analysis for QUEST 1 and QUEST 2, demographics and baseline characteristics were balanced between both trials and between the OLYSIO and placebo treatment groups. In the pooled analysis of trials (QUEST 1 and QUEST 2), the 785 enrolled subjects had a median age of 47 years (range: 18 to 73 years); 56% were male; 91% were White, 7% Black or African American, 1% Asian, and 17% Hispanic; 23% had a body mass index (BMI) greater than or equal to 30 kg/m2; 78% had HCV RNA levels greater than 800000 IU/mL; 74% had METAVIR fibrosis score F0, F1 or F2, 16% METAVIR fibrosis score F3, and 10% METAVIR fibrosis score F4 (cirrhosis); 48% had HCV genotype 1a, and 51% HCV genotype 1b; 29% had IL28B CC genotype, 56% IL28B CT genotype, and 15% IL28B TT genotype; 17% of the overall population and 34% of the subjects with genotype 1a virus had the NS3 Q80K polymorphism at baseline. In QUEST 1, all subjects received Peg-IFN-alfa-2a; in QUEST 2, 69% of the subjects received Peg-IFN-alfa-2a and 31% received Peg-IFN-alfa-2b.

Table 11 shows the response rates in treatment-naïve adult subjects with HCV genotype 1 infection. In the OLYSIO treatment group, SVR12 rates were lower in subjects with genotype 1a virus with the NS3 Q80K polymorphism at baseline compared to subjects infected with genotype 1a virus without the Q80K polymorphism.

In the pooled analysis of QUEST 1 and QUEST 2, 88% (459/521) of OLYSIO-treated subjects were eligible for a total treatment duration of 24 weeks. In these subjects, the SVR12 rate was 88% (405/459).

Seventy-eight percent (78%; 404/521) of OLYSIO-treated subjects had HCV RNA not detected at Week 4 (RVR); in these subjects the SVR12 rate was 90% (362/404), while 8% (32/392) with HCV RNA not detected at end of treatment had viral relapse.

SVR12 rates were higher for the OLYSIO treatment group compared to the placebo treatment group by sex, age, race, BMI, HCV genotype/subtype, baseline HCV RNA load (less than or equal to 800000 IU/mL, greater than 800000 IU/mL), METAVIR fibrosis score, and IL28B genotype. Table 12 shows the SVR rates by METAVIR fibrosis score.

SVR12 rates were higher for subjects receiving OLYSIO with Peg-IFN-alfa-2a or Peg-IFN-alfa-2b and RBV (88% and 78%, respectively) compared to subjects receiving placebo with Peg-IFN-alfa-2a or Peg-IFN-alfa-2b and RBV (62% and 42%, respectively) (QUEST 2).

Adult Subjects with HCV Genotype 1 Infection who Failed Prior Peg-IFN-alfa and RBV Therapy

The PROMISE trial was a randomized, double-blind, placebo-controlled, 2-arm, multicenter, Phase 3 trial in subjects with HCV genotype 1 infection who relapsed after prior IFN-based therapy. All subjects received 12 weeks of once daily treatment with 150 mg OLYSIO or placebo, plus Peg-IFN-alfa-2a and RBV, followed by 12 or 36 weeks of therapy with Peg-IFN-alfa-2a and RBV in accordance with the protocol-defined RGT criteria. Subjects in the control group received 48 weeks of Peg-IFN-alfa-2a and RBV.

Demographics and baseline characteristics were balanced between the OLYSIO and placebo treatment groups. The 393 subjects enrolled in the PROMISE trial had a median age of 52 years (range: 20 to 71 years); 66% were male; 94% were White, 3% Black or African American, 2% Asian, and 7% Hispanic; 26% had a BMI greater than or equal to 30 kg/m2; 84% had HCV RNA levels greater than 800000 IU/mL; 69% had METAVIR fibrosis score F0, F1 or F2, 15% METAVIR fibrosis score F3, and 15% METAVIR fibrosis score F4 (cirrhosis); 42% had HCV genotype 1a, and 58% HCV genotype 1b; 24% had IL28B CC genotype, 64% IL28B CT genotype, and 12% IL28B TT genotype; 13% of the overall population and 31% of the subjects with genotype 1a virus had the NS3 Q80K polymorphism at baseline. The prior IFN-based HCV therapy was Peg-IFN-alfa-2a/RBV (68%) or Peg-IFN-alfa-2b/RBV (27%).

Table 13 shows the response rates for the OLYSIO and placebo treatment groups in adult subjects with HCV genotype 1 infection who relapsed after prior interferon-based therapy. In the OLYSIO treatment group, SVR12 rates were lower in subjects infected with genotype 1a virus with the NS3 Q80K polymorphism at baseline compared to subjects infected with genotype 1a virus without the Q80K polymorphism.
