Refer to the ribavirin prescribing information for a list of contraindications for ribavirin. • TECHNIVIE is contraindicated: ◦ In patients with severe hepatic impairment due to risk of potential toxicity [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3)]. ◦ With drugs that are highly dependent on CYP3A for clearance and for which elevated plasma concentrations are associated with serious and/or life-threatening events. ◦ With drugs that are moderate or strong inducers of CYP3A and may lead to reduced efficacy of TECHNIVIE. ◦ In patients with known hypersensitivity to ritonavir (e.g. toxic epidermal necrolysis (TEN) or Stevens-Johnson syndrome). Table 2 lists drugs that are contraindicated with TECHNIVIE [see Drug Interactions (7)]. Table 2. Drugs that are Contraindicated with TECHNIVIE Drug Class Drug(s) within Class that are Contraindicated Clinical Comments Alpha1­ adrenoreceptor antagonist Alfuzosin HCl Potential for hypotension. Anticonvulsants Carbamazepine, phenytoin, phenobarbital Ombitasvir, paritaprevir and ritonavir exposures may decrease leading to a potential loss of therapeutic activity of TECHNIVIE. Antimycobacterial Rifampin Ombitasvir, paritaprevir and ritonavir exposures may decrease leading to a potential loss of therapeutic activity of TECHNIVIE. Reference ID: 3796943 Page 3 of 36 Drug Class Drug(s) within Class that are Contraindicated Clinical Comments Ergot derivatives Ergotamine, dihydroergotamine, ergonovine, methylergonovine Acute ergot toxicity characterized by vasospasm and tissue ischemia has been associated with co-administration of ritonavir and ergonovine, ergotamine, dihydroergotamine, or methylergonovine. Ethinyl estradiol­ containing products Ethinyl estradiol­ containing medications such as combined oral contraceptives Potential for ALT elevations [see Warnings and Precautions (5.1)]. Herbal Product St. John’s Wort (Hypericum perforatum) Ombitasvir, paritaprevir and ritonavir exposures may decrease leading to a potential loss of therapeutic activity of TECHNIVIE. HMG-CoA Reductase Inhibitors Lovastatin, simvastatin Potential for myopathy including rhabdomyolysis. Neuroleptics Pimozide Potential for cardiac arrhythmias. Non-nucleoside reverse transcriptase inhibitor Efavirenz Co-administration of efavirenz based regimens with paritaprevir, ritonavir was poorly tolerated and resulted in liver enzyme elevations. Phosphodiesterase-5 (PDE5) inhibitor Sildenafil when dosed as REVATIO for the treatment of pulmonary arterial hypertension (PAH) There is increased potential for sildenafil­ associated adverse events such as visual disturbances, hypotension, priapism, and syncope. Sedatives/hypnotics Triazolam Orally administered midazolam Triazolam and orally administered midazolam are extensively metabolized by CYP3A4. Coadministration of triazolam or orally administered midazolam with TECHNIVIE may cause large increases in the concentration of these benzodiazepines. The potential exists for serious and/or life threatening events such as prolonged or increased sedation or respiratory depression. Reference ID: 3796943 Page 4 of 36 5 WARNINGS AND PRECAUTIONS 5.1 Increased Risk of ALT Elevations During clinical trials with ombitasvir, paritaprevir and ritonavir with or without dasabuvir and with or without ribavirin, elevations of ALT to greater than 5 times the upper limit of normal (ULN) occurred in approximately 1% of subjects [see Adverse Reactions (6.1)]. ALT elevations were typically asymptomatic, occurred during the first 4 weeks of treatment, and declined within two to eight weeks of onset with continued dosing. These ALT elevations were significantly more frequent in female subjects who were using ethinyl estradiol-containing medications such as combined oral contraceptives, contraceptive patches or contraceptive vaginal rings. Ethinyl estradiol-containing medications must be discontinued prior to starting therapy with TECHNIVIE [see Contraindications (4)]. Alternative methods of contraception (e.g., progestin only contraception or non-hormonal methods) are recommended during TECHNIVIE therapy. Ethinyl estradiol-containing medications can be restarted approximately 2 weeks following completion of treatment with TECHNIVIE. Women using estrogens other than ethinyl estradiol, such as estradiol and conjugated estrogens used in hormone replacement therapy had a rate of ALT elevation similar to those not receiving any estrogens. Due to the limited number of subjects taking these other estrogens in clinical studies, caution is warranted for co-administration with TECHNIVIE [see Adverse Reactions (6.1)]. Hepatic laboratory testing should be performed during the first 4 weeks of starting treatment and as clinically indicated thereafter. If ALT is found to be elevated above baseline levels, it should be repeated and monitored closely: • Patients should be instructed to consult their health care professional without delay if they have onset of fatigue, weakness, lack of appetite, nausea and vomiting, jaundice or discolored feces. • Consider discontinuing TECHNIVIE if ALT levels remain persistently greater than 10 times the ULN. • Discontinue TECHNIVIE if ALT elevation is accompanied by signs or symptoms of liver inflammation or increasing conjugated bilirubin, alkaline phosphatase, or INR. 5.2 Risks Associated With Ribavirin Combination Treatment The warnings and precautions for ribavirin, in particular the pregnancy avoidance warning, apply to this combination regimen. Refer to the ribavirin prescribing information for a full list of the warnings and precautions for ribavirin. 5.3 Risk of Adverse Reactions or Reduced Therapeutic Effect Due to Drug Interactions The concomitant use of TECHNIVIE and certain other drugs may result in known or potentially significant drug interactions, some of which may lead to: • Loss of therapeutic effect of TECHNIVIE and possible development of resistance • Possible clinically significant adverse reactions from greater exposures of concomitant drugs or components of TECHNIVIE. Reference ID: 3796943 Page 5 of 36 See Table 4 for steps to prevent or manage these possible and known significant drug interactions, including dosing recommendations [see Drug Interactions (7)]. Consider the potential for drug interactions prior to and during TECHNIVIE therapy; review concomitant medications during TECHNIVIE therapy; and monitor for the adverse reactions associated with the concomitant drugs [see Contraindications (4) and Drug Interactions (7)]. 5.4 Risk of HIV-1 Protease Inhibitor Drug Resistance in HCV/HIV-1 Co-infected Patients The ritonavir component of TECHNIVIE is also an HIV-1 protease inhibitor and can select for HIV-1 protease inhibitor resistance-associated substitutions. Any HCV/HIV-1 co-infected patients treated with TECHNIVIE should also be on a suppressive antiretroviral drug regimen to reduce the risk of HIV-1 protease inhibitor drug resistance. 6 ADVERSE REACTIONS TECHNIVIE should be administered with ribavirin (RBV). Refer to the prescribing information for ribavirin for a list of ribavirin-associated adverse reactions. The following adverse reaction is described below and elsewhere in the labeling: • Increased Risk of ALT Elevations [see Warnings and Precautions (5.1)] 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of ombitasvir, paritaprevir and ritonavir cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety assessment of TECHNIVIE is based on data from a clinical study that included 135 HCV genotype 4-infected subjects without cirrhosis, 91 who received ombitasvir 25 mg, paritaprevir 150 mg and ritonavir 100 mg (administered as one ombitasvir 25 mg tablet, three paritaprevir 50 mg tablets and one ritonavir 100 mg capsule) once daily with ribavirin for 12 weeks and 44 subjects without cirrhosis who received ombitasvir 25 mg, paritaprevir 150 mg, and ritonavir 100 mg (administered as one ombitasvir 25 mg tablet, three paritaprevir 50 mg tablets and one ritonavir 100 mg capsule) once daily without ribavirin for 12 weeks (PEARL-I). Adverse reactions that occurred in subjects treated with ombitasvir, paritaprevir and ritonavir with or without ribavirin for 12 weeks are listed in Table 3. The majority of adverse reactions in PEARL-I were mild in severity. None of the subjects who received ombitasvir, paritaprevir and ritonavir with ribavirin experienced a serious adverse reaction. None of the subjects receiving ombitasvir, paritaprevir and ritonavir with or without ribavirin discontinued treatment due to an adverse reaction. Table 3. Selected Adverse Reactions (All Grades) with ≥5% Frequency Reported in Subjects Treated with Ombitasvir, Paritaprevir and Ritonavir with or without Ribavirin for 12 Weeks Reference ID: 3796943 Page 6 of 36 PEARL-I Ombitasvir, paritaprevir, Ombitasvir, paritaprevir, ritonavir + RBV ritonavir 12 Weeks 12 Weeks Adverse Reaction N = 91 N = 44 % % Asthenia 29 25 Fatigue 15 7 Nausea 14 9 Insomnia 13 5 Pruritus* 7 5 $,# Skin reactions 7 5 *Grouped term ‘pruritus’ includes the preferred terms pruritus and pruritus generalized. $ Grouped term ‘skin reactions’ includes the preferred terms rash, erythema, eczema, rash maculo-papular, rash macular, dermatitis, rash papular, skin exfoliation, rash pruritic, rash erythematous, rash generalized, dermatitis allergic, dermatitis contact, exfoliative rash, photosensitivity reaction, psoriasis, skin reaction, ulcer and urticaria. # The majority of events were graded as mild in severity. There were no serious events or severe cutaneous reactions, such as Stevens Johnson Syndrome (SJS), toxic epidermal necrolysis (TEN), erythema multiforme (EM) or drug rash with eosinophilia and systemic symptoms (DRESS). Laboratory Abnormalities Serum ALT Elevations None of the 135 HCV GT4 infected subjects treated with TECHNIVIE experienced postbaseline serum ALT levels greater than 5 times the upper limit of normal (ULN) after starting treatment [see Warnings and Precautions (5.1)]. Serum Bilirubin Elevations Post-baseline elevations in bilirubin at least 2 times ULN were observed in 5% (7/134) of subjects receiving TECHNIVIE; all of whom were also receiving RBV. These bilirubin increases were predominately indirect and related to the inhibition of the bilirubin transporters OATP1B1/1B3 by paritaprevir and possibly ribavirin-induced hemolysis. Bilirubin elevations occurred early after initiation of treatment, peaked by study Week 1, and generally resolved with ongoing therapy. Bilirubin elevations were generally not associated with serum ALT elevations. Anemia/Decreased Hemoglobin The mean change from baseline in hemoglobin levels in subjects treated with TECHNIVIE in combination with ribavirin was -2.1 g/dL and the mean change in subjects treated with TECHNIVIE alone was -0.4 g/dL. Decreases in hemoglobin levels occurred early in treatment (Week 1-2) with further reductions through Week 3. Hemoglobin values remained low during the remainder of treatment and returned towards Reference ID: 3796943 Page 7 of 36 baseline levels by post-treatment Week 4. One subject treated with TECHNIVIE with ribavirin had a single hemoglobin level decrease to less than 8 g/dL during treatment. Four percent (4/91) of subjects treated with TECHNIVIE with ribavirin underwent ribavirin dose reductions to manage anemia/decreased hemoglobin levels; none received a blood transfusion or erythropoietin. No subjects treated with TECHNIVIE alone had a hemoglobin level less than 8 g/dL. 6.2 Post-Marketing Experience Hypersensitivity reactions (including angioedema) have been observed. 7 DRUG INTERACTIONS 7.1 Potential for TECHNIVIE to Affect Other Drugs Paritaprevir is an inhibitor of OATP1B1 and OATP1B3 and paritaprevir and ritonavir are inhibitors of BCRP and P-gp. Ritonavir is an inhibitor of CYP3A4. Co-administration of TECHNIVIE with drugs that are substrates of CYP3A, P-gp, BCRP, OATP1B1 or OATP1B3 may result in increased plasma concentrations of such drugs. 7.2 Potential for Other Drugs to Affect One or More Components of TECHNIVIE Paritaprevir and ritonavir are primarily metabolized by CYP3A enzymes. Co-administration of TECHNIVIE with strong inhibitors of CYP3A may increase paritaprevir and ritonavir concentrations. Ombitasvir is primarily metabolized via amide hydrolysis while CYP enzymes play a minor role in its metabolism. Ombitasvir, paritaprevir and ritonavir are substrates of P-gp. Paritaprevir is a substrate of BCRP, OATP1B1 and OATP1B3. Inhibition of P-gp, BCRP, OATP1B1 or OATP1B3 may increase the plasma concentrations of the various components of TECHNIVIE. 7.3 Established and Other Potential Drug Interactions If dosage adjustments of concomitant medications are made due to treatment with TECHNIVIE, dosages should be re-adjusted after administration of TECHNIVIE is completed. Dosage adjustment is not required for TECHNIVIE. Table 4 provides the effect of co-administration of TECHNIVIE on concentrations of concomitant drugs and the effect of concomitant drugs on the various components of TECHNIVIE. See Contraindications (4) for drugs that are contraindicated with TECHNIVIE. Refer to the ritonavir prescribing information for other potentially significant drug interactions with ritonavir.

Appropriate monitoring of serum digoxin levels is recommended. Caution is warranted and therapeutic concentration monitoring (if available) is recommended for antiarrhythmics when co­ administered with TECHNIVIE. When TECHNIVIE is co-administered with ketoconazole, the maximum daily dose of ketoconazole should be limited to 200 mg per day. Co-administration of TECHNIVIE with voriconazole is not recommended unless an assessment of the benefit-to-risk ratio justifies the use of voriconazole. • Initiation of TECHNIVIE in patients taking quetiapine: Consider alternative anti-HCV therapy to avoid increases in quetiapine exposures. If coadministration is necessary, reduce the quetiapine dose to 1/6th of the current dose and monitor for quetiapine-associated adverse reactions. Refer to the quetiapine prescribing information for recommendations on adverse reaction monitoring. • Initiation of quetiapine in patients taking TECHNIVIE: Refer to the quetiapine prescribing information for initial dosing and titration of quetiapine. Consider dose reduction for amlodipine. Clinical monitoring is recommended. Concomitant Drug Effect on Clinical Comments Class: Drug Name Concentration CORTICOSTEROIDS (INHALED/NASAL) fluticasone* ↑ fluticasone Concomitant use of TECHNIVIE with inhaled or nasal fluticasone may reduce serum cortisol concentrations. Alternative corticosteroids should be considered, particularly for long term use. DIURETICS furosemide ↑ furosemide (C max ) Clinical monitoring of patients is recommended and therapy should be individualized based on patient’s response. HIV-ANTIVIRAL AGENTS atazanavir or ↑ paritaprevir Co-administration of TECHNIVIE with atazanavir/ritonavir atazanavir or atazanavir/ritonavir is not recommended. darunavir/ritonavir ↓ darunavir (C trough ) When co-administered with TECHNIVIE, darunavir 800 mg (without ritonavir) should be taken at the same time as TECHNIVIE. lopinavir/ritonavir ↑ paritaprevir Co-administration of TECHNIVIE with lopinavir/ritonavir is not recommended. rilpivirine ↑ rilpivirine Co-administration of TECHNIVIE with rilpivirine once daily is not recommended due to potential for QT interval prolongation with higher concentrations of rilpivirine.

IMMUNOSUPPRESSANTS cyclosporine ↑ cyclosporine When initiating therapy with TECHNIVIE, reduce cyclosporine dose to 1/5th of the patient’s current cyclosporine dose. Measure cyclosporine blood concentrations to determine subsequent dose modifications. Upon completion of TECHNIVIE therapy, the appropriate time to resume preTECHNIVIE dose of cyclosporine should be guided by assessment of cyclosporine blood concentrations. Frequent assessment of renal function and cyclosporine-related side effects is recommended. Reference ID: 3796943 Page 10 of 36 Concomitant Drug Class: Drug Name tacrolimus Effect on Concentration ↑ tacrolimus Clinical Comments When initiating therapy with TECHNIVIE, the dose of tacrolimus needs to be reduced. Do not administer tacrolimus on the day TECHNIVIE is initiated. Beginning the day after TECHNIVIE is initiated; reinitiate tacrolimus at a reduced dose based on tacrolimus blood concentrations. Typical tacrolimus dosing is 0.5 mg every 7 days. Measure tacrolimus blood concentrations and adjust dose or dosing frequency to determine subsequent dose modifications. Upon completion of TECHNIVIE therapy, the appropriate time to resume pre-TECHNIVIE dose of tacrolimus should be guided by assessment of tacrolimus blood concentrations. Frequent assessment of renal function and tacrolimus related side effects is recommended. LONG ACTING BETA-ADRENOCEPTOR AGONIST salmeterol* ↑ salmeterol Concurrent administration of TECHNIVIE and salmeterol is not recommended.

The direction of the arrow indicates the direction of the change in exposures (C max and AUC) (↑ = increase of more than 20%, ↓ = decrease of more than 20%). 7.4 Drugs without Clinically Significant Interactions with TECHNIVIE No dosage adjustments are recommended when TECHNIVIE is co-administered with the following medications: duloxetine, emtricitabine/tenofovir disoproxil fumarate, escitalopram, gemfibrozil, methadone, progestin only contraceptives, raltegravir, rosuvastatin, warfarin and zolpidem. 8 USE IN SPECIFIC POPULATIONS 8.1 Pregnancy Pregnancy Category B Risk Summary Adequate and well controlled studies with TECHNIVIE have not been conducted in pregnant women. In animal reproduction studies, no evidence of teratogenicity was observed with the administration of ombitasvir (mice and rabbits), paritaprevir or ritonavir (mice and rats) at exposures higher than the recommended clinical dose [see Data]. Because animal reproduction studies are not always predictive of human response, TECHNIVIE should be used during pregnancy only if clearly needed. When TECHNIVIE is administered with ribavirin, the combination regimen is contraindicated in pregnant women and in men whose female partners are pregnant. Refer to the ribavirin prescribing information for more information on use of ribavirin in males and females of child-bearing potential. Data Animal data In animal reproduction studies, there was no evidence of teratogenicity in offspring born to animals treated throughout pregnancy with ombitasvir and its major inactive human metabolites (M29, M36), paritaprevir or ritonavir. For ombitasvir, the highest dose tested produced exposures approximately 29-fold (mouse) or 4-fold (rabbit) the exposures in humans at the recommended clinical dose. The highest doses of the major, inactive human metabolites similarly tested produced exposures approximately 26-fold the exposures in humans at the recommended clinical dose. For paritaprevir, ritonavir, the highest doses tested produced exposures approximately 143-fold (mouse) or 12-fold (rat) the exposures of paritaprevir in humans at the recommended clinical dose. Reference ID: 3796943 Page 12 of 36 8.3 Nursing Mothers It is not known whether any of the components of TECHNIVIE or their metabolites are present in human milk. Unchanged ombitasvir, paritaprevir and its hydrolysis product M13 were the predominant components observed in the milk of lactating rats, without effect on nursing pups. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for TECHNIVIE and any potential adverse effects on the breastfed child from TECHNIVIE or from the underlying maternal condition. When TECHNIVIE is administered with ribavirin, the nursing mother’s information for ribavirin also applies to this combination regimen (see prescribing information for ribavirin). 8.4 Pediatric Use Safety and effectiveness of TECHNIVIE in pediatric patients less than 18 years of age have not been established. 8.5 Geriatric Use No dosage adjustment of TECHNIVIE is warranted in geriatric patients. Clinical study PEARL-I did not include sufficient numbers of patients older than 65 years of age to assess safety or efficacy, or to determine if they responded differently than younger patients. 8.6 Hepatic Impairment No dosage adjustment of TECHNIVIE is required in patients with mild hepatic impairment (Child-Pugh A). TECHNIVIE is not recommended in HCV-infected patients with moderate hepatic impairment (Child-Pugh B) because the safety has not been established. TECHNIVIE is contraindicated in patients with severe (Child-Pugh C) hepatic impairment [see Dosage and Administration (2.2), Contraindications (4) and Clinical Pharmacology (12.3)]. 8.7 Renal Impairment No dosage adjustment of TECHNIVIE is required in patients with mild, moderate or severe renal impairment. TECHNIVIE has not been studied in patients on dialysis. For patients that require ribavirin, refer to the ribavirin prescribing information for information regarding use in patients with renal impairment [see Clinical Pharmacology (12.3)]. 10 OVERDOSAGE In case of overdose, it is recommended that the patient be monitored for any signs or symptoms of adverse reactions and appropriate symptomatic treatment be instituted immediately. 11 DESCRIPTION TECHNIVIE is a fixed-dose combination tablet containing ombitasvir, paritaprevir, and ritonavir for oral administration.

Reference ID: 3796943 Page 15 of 36 12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action TECHNIVIE combines two direct-acting hepatitis C virus antiviral agents with distinct mechanisms of action [see Microbiology (12.4)]. Ritonavir is not active against HCV. Ritonavir is a potent CYP3A inhibitor that increases peak and trough plasma drug concentrations of paritaprevir and overall drug exposure (i.e., area under the curve). 12.2 Pharmacodynamics Cardiac Electrophysiology The effect of a combination of ombitasvir, paritaprevir and ritonavir plus dasabuvir on QTc interval was evaluated in a randomized, double blind, placebo and active-controlled (moxifloxacin 400 mg) 4-way crossover thorough QT study in 60 healthy subjects. At concentrations approximately 6 and 1.8 times the therapeutic concentrations of paritaprevir and ombitasvir, the combination did not prolong QTc to any clinically relevant extent. 12.3 Pharmacokinetics Absorption Ombitasvir, paritaprevir and ritonavir were absorbed after oral administration with mean T max of approximately 4 to 5 hours. While ombitasvir exposures increased in a dose proportional manner, paritaprevir and ritonavir exposures increased in a more than dose proportional manner. Accumulation is minimal for ombitasvir and approximately 1.5- to 2­ fold for ritonavir and paritaprevir. Steady state exposures are achieved after approximately 12 days of dosing. The absolute bioavailability of ombitasvir and paritaprevir when administered with ritonavir as TECHNIVIE was approximately 48.1% and 52.6%, respectively. Based on the population pharmacokinetic analysis, the median steady-state AUC 0-24 for ombitasvir, paritaprevir and ritonavir were 1239, 2276 and 6072 ng·hr/mL, respectively, when administered to HCV genotype 4-infected subjects. Median steady-state C max for ombitasvir, paritaprevir, and ritonavir were 82, 194 and 543 ng/mL, respectively, when administered to HCV genotype 4-infected subjects. Effects of Food on Oral Absorption Relative to fasting conditions, administration of ombitasvir, paritaprevir and ritonavir with a moderate fat meal (approximately 600 Kcal, 20-30% calories from fat) increased the mean AUC by 82%, 211% and 49%, respectively. Relative to fasting conditions, administration of ombitasvir, paritaprevir and ritonavir with a high fat meal (approximately 900 Kcal, 60% calories from fat) increased the mean AUC by 76%, 180%, and 44%, respectively. Ombitasvir, paritaprevir, and ritonavir should always be administered with a meal. Reference ID: 3796943 Page 16 of 36 Distribution Ombitasvir: Ombitasvir was approximately 99.9% bound to human plasma proteins over a concentration range of 0.09 to 9 µg per mL. The mean blood-to-plasma concentration ratio was 0.49. The volume of distribution (V) was 173 L. Paritaprevir: Paritaprevir was approximately 97 to 98.6% bound to human plasma proteins over a concentration range of 0.08 to 8 µg per mL. The mean blood-to-plasma concentration ratio was 0.7. The volume of distribution (V) was 103 L. Ritonavir: Ritonavir was greater than 99% bound to human plasma proteins over a concentration range of 0.007 to 22 µg per mL. The mean blood-to-plasma concentration ratio was 0.6. Metabolism Ombitasvir: Ombitasvir is predominantly metabolized by amide hydrolysis followed by oxidative metabolism. Paritaprevir: Paritaprevir is predominantly metabolized by CYP3A4 and to a lesser extent by CYP3A5. Ritonavir: Ritonavir is predominantly metabolized by CYP3A, and to a lesser extent by CYP2D6. Elimination Ombitasvir: Following a single dose administration of 14C-ombitasvir, approximately 90.2% of the radioactivity was recovered in feces with limited radioactivity (1.91%) in urine; unchanged ombitasvir accounted for 87.8% of the radioactivity in the feces and 0.03% in the urine. The mean elimination half-life of ombitasvir was approximately 21 to 25 hours. Paritaprevir: Following a single dose administration of 14C-paritaprevir co-dosed with 100 mg of ritonavir, approximately 88% of the radioactivity was recovered in feces with limited radioactivity (8.8%) in urine; unchanged paritaprevir accounted for 1.1% of the radioactivity in the feces and 0.05% in the urine. The mean plasma half-life of paritaprevir was approximately 5.5 hours. Ritonavir: Following dosing of ritonavir with ombitasvir and paritaprevir, mean plasma half-life of ritonavir was approximately 4 hours. Following a single 600 mg dose of 14C­ ritonavir oral solution, 86.4% of the radioactivity was recovered in the feces and 11.3% of the dose was excreted in the urine. Ombitasvir, paritaprevir and ritonavir do not inhibit organic anion transporter (OAT1) in vivo and, based on in vitro data, are not expected to inhibit organic cation transporter (OCT2), organic anion transporter (OAT3), or multidrug and toxin extrusion proteins (MATE1 and MATE2K) at clinically relevant concentrations. Ombitasvir, paritaprevir and ritonavir are neither inhibitors nor substrates of organic cation transporter 1 (OCT1). Specific Populations Reference ID: 3796943 Page 17 of 36 Hepatic Impairment The single dose pharmacokinetics of ombitasvir, paritaprevir, ritonavir and another antiviral drug were evaluated in non-HCV infected subjects with mild hepatic impairment (Child-Pugh A; score of 5-6), moderate hepatic impairment (Child-Pugh B, score of 7-9) and severe hepatic impairment (Child-Pugh C, score of 10-15). Relative to subjects with normal hepatic function, ombitasvir, paritaprevir and ritonavir mean AUC values decreased by 8%, 29% and 34%, respectively, in subjects with mild hepatic impairment. Relative to subjects with normal hepatic function, ombitasvir and ritonavir mean AUC values decreased by 30% and 30%, respectively and paritaprevir mean AUC values increased by 62% in subjects with moderate hepatic impairment. Relative to subjects with normal hepatic function, paritaprevir and ritonavir mean AUC values increased by 945% and 13% respectively and ombitasvir mean AUC values decreased by 54% in subjects with severe hepatic impairment. Renal Impairment The single dose pharmacokinetics of ombitasvir, paritaprevir and ritonavir were evaluated in non-HCV infected subjects with mild (CLcr : 60 to 89 mL/min), moderate (CLcr : 30 to 59 mL/min), and severe (CLcr : 15 to 29 mL/min) renal impairment. Overall, changes in exposure of ombitasvir, paritaprevir, and ritonavir in non-HCV infected subjects with mild-, moderate- and severe renal impairment are not expected to be clinically relevant. Pharmacokinetic data are not available on the use of TECHNIVIE in non-HCV infected subjects with End Stage Renal Disease (ESRD). Relative to subjects with normal renal function, ritonavir AUC values increased by 40%, while ombitasvir and paritaprevir AUC values were unchanged in subjects with mild renal impairment. Relative to subjects with normal renal function, ritonavir AUC values increased by 76%, while ombitasvir and paritaprevir AUC values were unchanged in subjects with moderate renal impairment. Relative to subjects with normal renal function, paritaprevir and ritonavir AUC values increased by 25% and 108%, respectively, while ombitasvir AUC values were unchanged in subjects with severe renal impairment.

Ombitasvir Ombitasvir is an inhibitor of HCV NS5A, which is essential for viral RNA replication and virion assembly. The mechanism of action of ombitasvir has been characterized based on cell culture antiviral activity and drug resistance mapping studies. Paritaprevir Paritaprevir is an inhibitor of HCV NS3/4A protease which is necessary for the proteolytic cleavage of the HCV encoded polyprotein (into mature forms of the NS3, NS4A, NS4B, NS5A, and NS5B proteins) and is essential for viral replication. In a biochemical assay, paritaprevir inhibited the proteolytic activity of a recombinant HCV genotype 4a NS3/4A protease enzyme with an IC 50 value of 0.16 nM. Paritaprevir inhibited the activity of NS3/4A enzymes from single isolates of genotypes 1a, 1b, 2a, 2b, and 3a with IC 50 values of 0.18 nM, 0.43 nM, 2.4 nM, 6.3 nM, and 14.5 nM, respectively. Antiviral Activity Ombitasvir The EC 50 values of ombitasvir against HCV replicons containing NS5A from a single isolate each of genotype 4a and genotype 4d were 1.7 pM and 0.38 pM, respectively. Ombitasvir had a median EC 50 value of 0.21 pM (range 0.10 pM to 0.36 pM; n=9) against transient HCV replicons containing NS5A genes from a panel of genotype 4a isolates from treatment-naïve subjects. Ombitasvir had EC 50 values of 14 pM, 5.0 pM, 12 pM, 4.3 pM, 19 pM, 3.2 pM, and 366 pM against replicon cell lines representing genotypes 1a­ H77, 1b-Con1, 2a, 2b, 3a, 5a and 6a, respectively. Paritaprevir The EC 50 values of paritaprevir against HCV replicons containing NS3 from a single isolate each of genotype 4a and genotype 4d were 0.09 nM and 0.015 nM, respectively. Reference ID: 3796943 Page 26 of 36 Paritaprevir had EC 50 values of 1.0 nM, 0.21 nM, 5.3 nM, 19 nM and 0.68 nM against replicon cell lines representing genotypes 1a-H77, 1b-Con1, 2a-JFH1, 3a and 6a, respectively. Ritonavir In HCV replicon cell culture assays, ritonavir did not exhibit a direct antiviral effect and the presence of ritonavir did not affect the antiviral activity of paritaprevir. Resistance In Cell Culture Exposure of HCV genotype 4a replicons to ombitasvir or paritaprevir resulted in the emergence of drug resistant replicons carrying amino acid substitutions in NS5A or NS3, respectively. Amino acid substitutions in NS5A or NS3 selected in cell culture or identified in clinical study PEARL-I were phenotypically characterized in genotype 4 replicons. For ombitasvir, in an HCV genotype 4a replicon, NS5A substitution L28V reduced ombitasvir antiviral activity by 21-fold. In an HCV genotype 4d replicon, substitutions L28V alone and L28V in combination with T58S reduced ombitasvir antiviral activity by 310- and 760-fold, respectively. Ombitasvir activity against an HCV genotype 4d replicon was not reduced by a T58P polymorphism, which represents the consensus sequence observed at this position for HCV genotype 4a and 4d subjects in PEARL-I. For paritaprevir, in an HCV genotype 4a replicon, NS3 substitutions R155C, A156T/V, and D168H/V reduced paritaprevir antiviral activity by 40- to 323-fold. In an HCV genotype 4d replicon, NS3 substitutions Y56H and D168V reduced paritaprevir antiviral activity by 8- and 313-fold, respectively, while a combination of Y56H and D168V reduced the activity of paritaprevir by 12,533-fold. In Clinical Studies In the clinical study PEARL-I, three subjects with HCV genotype 4 infection experienced virologic failure (2 post-treatment relapse, 1 on-treatment failure). All 3 virologic failures were observed in a regimen containing paritaprevir/ritonavir and ombitasvir without ribavirin. Treatment-emergent, resistance-associated substitutions were detected at the time of failure in all 3 subjects and included D168V (with or without Y56H) in NS3, and L28S and L28V (with or without M31I or T58S) in NS5A. Persistence of Resistance-Associated Substitutions The persistence of ombitasvir or paritaprevir resistance-associated amino acid substitutions in NS5A or NS3, respectively, in HCV genotype 4 has not been studied. In HCV genotype 1, persistence of ombitasvir and paritaprevir resistance-associated substitutions through 24 or 48 weeks post-treatment has been observed in subjects who experienced virologic failure with ombitasvir- and paritaprevir-containing regimens. The long-term clinical impact of the emergence or persistence of virus containing ombitasvir or paritaprevir resistance-associated substitutions is unknown. Reference ID: 3796943 Page 27 of 36 Effect of Baseline HCV Polymorphisms on Treatment Response Phylogenetic analysis of HCV sequences from genotype 4-infected subjects in the clinical study PEARL-I, identified 7 HCV genotype 4 subtypes (4a, 4b, 4c, 4d, 4f, 4g/4k, 4o). Most subjects were infected with either subtype 4a (38%) or 4d (52%); 1 to 7 subjects were infected with each of the other genotype 4 subtypes. Among subjects enrolled at U.S. study sites, 16/18 (89%) were infected with HCV subtype 4a; one subject each was infected with subtype 4c or 4d. Three subjects who experienced virologic failure with the regimen containing paritaprevir/ritonavir and ombitasvir without ribavirin were infected with HCV subtype 4d. Baseline HCV polymorphisms are not expected to impact the likelihood of achieving SVR when TECHNIVIE is used as recommended to treat HCV genotype 4 infected patients, based on the low virologic failure rate observed in PEARL-I. Cross-resistance Cross-resistance may occur among NS5A inhibitors and among NS3/4A protease inhibitors within each individual class. The impact of prior ombitasvir or paritaprevir treatment experience on the efficacy of other NS5A inhibitors or NS3/4A protease inhibitors has not been studied. Similarly, the efficacy of TECHNIVIE has not been studied in subjects who have failed prior treatment with another NS5A inhibitor, NS3/4A protease inhibitor, or NS5B inhibitor. 13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Carcinogenesis and Mutagenesis Ombitasvir Ombitasvir was not carcinogenic in a 6-month transgenic mouse study up to the highest dose tested (150 mg per kg per day). The carcinogenicity study of ombitasvir in rats is ongoing. Ombitasvir and its major inactive human metabolites (M29, M36) were not genotoxic in a battery of in vitro or in vivo assays, including bacterial mutagenicity, chromosome aberration using human peripheral blood lymphocytes and in vivo mouse micronucleus assays. Paritaprevir, ritonavir Paritaprevir, ritonavir was not carcinogenic in a 6-month transgenic mouse study up to the highest dose tested (300/30 mg per kg per day). Similarly, paritaprevir, ritonavir was not carcinogenic in a 2-year rat study up to the highest dose tested (300/30 mg per kg per day), resulting in paritaprevir exposures approximately 11-fold higher than those in humans at 150 mg. Reference ID: 3796943 Page 28 of 36 Paritaprevir was positive in an in vitro chromosome aberration test using human lymphocytes. Paritaprevir was negative in a bacterial mutation assay, and in two in vivo genetic toxicology assays (rat bone marrow micronucleus and rat liver Comet tests). TECHNIVIE is administered with ribavirin. Refer to the prescribing information for ribavirin for information on carcinogenesis and mutagenesis. Impairment of Fertility Ombitasvir Ombitasvir had no effects on embryo-fetal viability or on fertility when evaluated in mice up to the highest dose of 200 mg per kg per day. Ombitasvir exposures at this dose were approximately 26-fold the exposure in humans at the recommended clinical dose. Paritaprevir, ritonavir Paritaprevir, ritonavir had no effects on embryo-fetal viability or on fertility when evaluated in rats up to the highest dose of 300/30 mg per kg per day. Paritaprevir exposures at this dose were approximately 3- to 8-fold the exposure in humans at the recommended clinical dose. TECHNIVIE is administered with ribavirin. Refer to the prescribing information for ribavirin for information on Impairment of Fertility. 14 CLINICAL STUDIES 14.1 Clinical Trial Results in Adults with Chronic GT4 HCV Infection without Cirrhosis The efficacy and safety of TECHNIVIE was evaluated in a single clinical trial in subjects with genotype 4 (GT4) chronic hepatitis virus (HCV) infection. PEARL-I was a randomized, global, multicenter, open-label trial that enrolled 135 adults with HCV GT4 infection without cirrhosis who were either treatment-naïve or did not achieve a virologic response with prior treatment with pegylated interferon/ribavirin (pegIFN/RBV). Previous exposure to HCV direct-acting antivirals was prohibited. Treatment-naïve subjects were randomized in a 1:1 ratio to receive one ombitasvir 25 mg tablet, three paritaprevir 50 mg tablets and one ritonavir 100 mg capsule once-daily with food with or without ribavirin for 12 weeks. PegIFN/RBV treatment-experienced subjects received one ombitasvir 25 mg tablet, three paritaprevir 50 mg tablets and one ritonavir 100 mg capsule once-daily with food in combination with ribavirin for 12 weeks. The ribavirin dosage was 1000 mg per day for subjects weighing less than 75 kg or 1200 mg per day for subjects weighing greater than or equal to 75 kg. The primary endpoint was sustained virologic response defined as HCV RNA below the lower limit of quantification ( 1 log 10 IU/mL during treatment, or HCV RNA ≥ 25 IU/mL persistently during treatment with at least 6 weeks of treatment. b. Relapse was defined as confirmed HCV RNA ≥ 25 IU/mL post-treatment before or during SVR12 window among subjects with HCV RNA less than 25 IU/mL at last observation during at least 11 weeks of treatment. c. Other includes subjects not achieving SVR12 but not experiencing on-treatment VF or relapse (e.g. lost to follow-up). Among 131 HCV GT4 infected subjects in PEARL-I who achieved SVR12, virologic response data at post-treatment week 24 were available from 129 subjects, and 129/129 (100%) subjects maintained their response through 24 weeks post-treatment (SVR24). 16 HOW SUPPLIED/STORAGE AND HANDLING TECHNIVIE is dispensed in a monthly carton for a total of 28 days of therapy.
