Genvoya

1 INDICATIONS AND USAGE GENVOYA is indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 25 kg who have no antiretroviral treatment history or to replace the current antiretroviral regimen in those who are virologically-suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen for at least 6 months with no history of treatment failure and no known substitutions associated with resistance to the individual components of GENVOYA [see Clinical Studies (14) ]. GENVOYA is a four-drug combination of elvitegravir (EVG), an HIV-1 integrase strand transfer inhibitor (INSTI), cobicistat (COBI), a CYP3A inhibitor, and emtricitabine (FTC) and tenofovir alafenamide (TAF), both HIV-1 nucleoside analog reverse transcriptase inhibitors (NRTIs), and is indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 25 kg who have no antiretroviral treatment history or to replace the current antiretroviral regimen in those who are virologically-suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen for at least 6 months with no history of treatment failure and no known substitutions associated with resistance to the individual components of GENVOYA.

2 DOSAGE AND ADMINISTRATION Testing: Prior to or when initiating GENVOYA test for hepatitis B virus infection. Prior to or when initiating GENVOYA, and during treatment on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. ( 2.1 ) Recommended dosage in adult and pediatric patients weighing at least 25 kg: One tablet taken orally once daily with food in patients with body weight at least 25 kg and a creatinine clearance greater than or equal to 30 mL per minute, or in adult patients with creatinine clearance less than 15 mL per minute who are receiving chronic hemodialysis. On days of hemodialysis, administer GENVOYA after hemodialysis. ( 2.2 ) Renal impairment: GENVOYA is not recommended in patients with estimated creatinine clearance of 15 to below 30 mL per minute, or below 15 mL per minute who are not receiving chronic hemodialysis. ( 2.3 ) Hepatic impairment: GENVOYA is not recommended in patients with severe hepatic impairment. ( 2.4 ) 2.1 Testing When Initiating and During Treatment with GENVOYA Prior to or when initiating GENVOYA, test patients for hepatitis B virus infection [see Warnings and Precautions (5.1) ] . Prior to or when initiating GENVOYA, and during treatment with GENVOYA on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus [see Warnings and Precautions (5.4) ] . 2.2 Recommended Dosage in Adults and Pediatric Patients Weighing at Least 25 kg GENVOYA is a four-drug fixed dose combination product containing elvitegravir (EVG), cobicistat (COBI), emtricitabine (FTC), and tenofovir alafenamide (TAF). The recommended dosage of GENVOYA is one tablet containing 150 mg EVG,150 mg COBI, 200 mg FTC, and 10 mg TAF taken orally once daily with food in: adults and pediatric patients with body weight at least 25 kg and creatinine clearance greater than or equal to 30 mL per minute; or adults with creatinine clearance below 15 mL per minute who are receiving chronic hemodialysis. On days of hemodialysis, administer GENVOYA after completion of hemodialysis treatment [see Use in Specific Populations (8.6) and Clinical Pharmacology (12.3) ] . 2.3 Not Recommended in Patients with Severe Renal Impairment GENVOYA is not recommended in patients with: severe renal impairment (estimated creatinine clearance of 15 to below 30 mL per minute); or end stage renal disease (ESRD; estimated creatinine clearance below 15 mL per minute) who are not receiving chronic hemodialysis [see Dosage and Administration (2.2) and Use in Specific Populations (8.6) ] . 2.4 Not Recommended in Patients with Severe Hepatic Impairment GENVOYA is not recommended in patients with severe hepatic impairment (Child-Pugh Class C) [see Use in Specific Populations (8.7) and Clinical Pharmacology (12.3) ] . 2.5 Not Recommended During Pregnancy GENVOYA is not recommended for use during pregnancy because of substantially lower exposures of cobicistat and elvitegravir during the second and third trimesters [see Use in Specific Populations (8.1) ] . GENVOYA should not be initiated in pregnant individuals. An alternative regimen is recommended for individuals who become pregnant during therapy with GENVOYA [see Use in Specific Populations (8.1) ] .

4 CONTRAINDICATIONS Coadministration of GENVOYA is contraindicated 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. These drugs and other contraindicated drugs (which may lead to reduced efficacy of GENVOYA and possible resistance) are listed below [see Drug Interactions (7.5) and Clinical Pharmacology (12.3) ] . Alpha 1-adrenoreceptor antagonist: alfuzosin Anticonvulsants: carbamazepine, phenobarbital, phenytoin Antimycobacterial: rifampin Antipsychotics: lurasidone, pimozide Ergot Derivatives: dihydroergotamine, ergotamine, methylergonovine Herbal Products: St. John's wort ( Hypericum perforatum ) Lipid-modifying Agents: lomitapide, lovastatin, simvastatin Phosphodiesterase-5 (PDE-5) Inhibitor: sildenafil when administered as REVATIO ® for the treatment of pulmonary arterial hypertension Sedative/hypnotics: triazolam, orally administered midazolam Coadministration of GENVOYA is contraindicated with drugs that: Are highly dependent on CYP3A for clearance and for which elevated plasma concentrations are associated with serious adverse events. ( 4 ) Strongly induce CYP3A, which may lead to lower exposure of one or more components and loss of efficacy of GENVOYA and possible resistance. ( 4 )

5 WARNINGS AND PRECAUTIONS Risk of adverse reactions or loss of virologic response due to drug interactions: The concomitant use of GENVOYA and other drugs may result in known or potentially significant drug interactions, some of which may lead to loss of therapeutic effect of GENVOYA and possible development of resistance; clinically significant adverse reactions from greater exposures of concomitant drugs; or loss of therapeutic effect of concomitant drugs. ( 5.2 ) Immune reconstitution syndrome: May necessitate further evaluation and treatment. ( 5.3 ) New onset or worsening renal impairment: Assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein when initiating GENVOYA and during therapy on a clinically appropriate schedule in all patients. Also assess serum phosphorus in patients with chronic kidney disease. ( 5.4 ) Lactic acidosis/severe hepatomegaly with steatosis: Discontinue treatment in patients who develop symptoms or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity. ( 5.5 ) 5.1 Severe Acute Exacerbation of Hepatitis B in Patients Coinfected with HIV-1 and HBV Patients with HIV-1 should be tested for the presence of hepatitis B virus (HBV) before or when initiating antiretroviral therapy [see Dosage and Administration (2.1) ] . Severe acute exacerbations of hepatitis B (e.g., liver decompensation and liver failure) have been reported in patients who are coinfected with HIV-1 and HBV and have discontinued products containing emtricitabine and/or tenofovir disoproxil fumarate (TDF), and may occur with discontinuation of GENVOYA. Patients coinfected with HIV-1 and HBV who discontinue GENVOYA should be closely monitored with both clinical and laboratory follow-up for at least several months after stopping treatment. If appropriate, anti-hepatitis B therapy may be warranted, especially in patients with advanced liver disease or cirrhosis, since post-treatment exacerbation of hepatitis may lead to hepatic decompensation and liver failure. 5.2 Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions The concomitant use of GENVOYA and other drugs may result in known or potentially significant drug interactions, some of which may lead to [see Contraindications (4) and Drug Interactions (7.5) ]: Loss of therapeutic effect of GENVOYA and possible development of resistance. Clinically significant adverse reactions, potentially leading to severe, life-threatening, or fatal events, from greater exposures of concomitant drugs metabolized by CYP3A. Loss of therapeutic effect of concomitant drugs that utilize CYP3A to form active metabolites. See Table 5 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 GENVOYA therapy; review concomitant medications during GENVOYA therapy; and monitor for the adverse reactions associated with the concomitant drugs. 5.3 Immune Reconstitution Syndrome Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including emtricitabine, a component of GENVOYA. During the initial phase of combination antiretroviral treatment, patients whose immune system responds may develop an inflammatory response to indolent or residual opportunistic infections [such as Mycobacterium avium infection, cytomegalovirus, Pneumocystis jirovecii pneumonia (PCP), or tuberculosis], which may necessitate further evaluation and treatment. Autoimmune disorders (such as Graves' disease, polymyositis, Guillain-Barré syndrome, and autoimmune hepatitis) have also been reported to occur in the setting of immune reconstitution, however, the time to onset is more variable, and can occur many months after initiation of treatment. 5.4 New Onset or Worsening Renal Impairment Postmarketing cases of renal impairment, including acute renal failure, proximal renal tubulopathy (PRT), and Fanconi syndrome have been reported with TAF-containing products; while most of these cases were characterized by potential confounders that may have contributed to the reported renal events, it is also possible these factors may have predisposed patients to tenofovir-related adverse events [see Adverse Reactions (6.1 , 6.2) ] . GENVOYA is not recommended in patients with estimated creatinine clearance of 15 to below 30 mL per minute, or in patients with estimated creatinine clearance below 15 mL per minute who are not receiving chronic hemodialysis. Patients taking tenofovir prodrugs who have impaired renal function and those taking nephrotoxic agents including non-steroidal anti-inflammatory drugs are at increased risk of developing renal-related adverse reactions. Prior to or when initiating GENVOYA, and during treatment with GENVOYA on a clinically appropriate schedule, assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. Discontinue GENVOYA in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Cobicistat, a component of GENVOYA, produces elevations of serum creatinine due to inhibition of tubular secretion of creatinine without affecting glomerular filtration [see Adverse Reactions (6.1) ] . The elevation is typically seen within 2 weeks of starting therapy and is reversible after discontinuation. Patients who experience a confirmed increase in serum creatinine of greater than 0.4 mg per dL from baseline should be closely monitored for renal safety. 5.5 Lactic Acidosis/Severe Hepatomegaly with Steatosis Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs, including emtricitabine, a component of GENVOYA, and tenofovir DF, another prodrug of tenofovir, alone or in combination with other antiretrovirals. Treatment with GENVOYA should be suspended in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity (which may include hepatomegaly and steatosis even in the absence of marked transaminase elevations).

7 DRUG INTERACTIONS GENVOYA should not be administered with other antiretroviral medications for treatment of HIV-1 infection. ( 7.1 ) GENVOYA can alter the concentration of drugs metabolized by CYP3A or CYP2D6. Drugs that induce CYP3A can alter the concentrations of one or more components of GENVOYA. Consult the full prescribing information prior to and during treatment for potential drug-drug interactions. ( 4 , 7.2 , 7.3 , 12.3 ) 7.1 Not Recommended with Other Antiretroviral Medications GENVOYA is a complete regimen for the treatment of HIV-1 infection; therefore, coadministration of GENVOYA with other antiretroviral medications for treatment of HIV-1 infection should be avoided. Complete information regarding potential drug-drug interactions with other antiretroviral medications is not provided [see Contraindications (4) , Warnings and Precautions (5.2) and Clinical Pharmacology (12.3) ] . 7.2 Potential for GENVOYA to Affect Other Drugs Cobicistat, a component of GENVOYA, is an inhibitor of CYP3A and CYP2D6 and an inhibitor of the following transporters: P-glycoprotein (P-gp), BCRP, OATP1B1 and OATP1B3. Thus, coadministration of GENVOYA with drugs that are primarily metabolized by CYP3A or CYP2D6, or are substrates of P-gp, BCRP, OATP1B1 or OATP1B3 may result in increased plasma concentrations of such drugs . Coadministration of GENVOYA with drugs that have active metabolite(s) formed by CYP3A may result in reduced plasma concentration of these active metabolite(s) (see Table 5 ). Elvitegravir is a modest inducer of CYP2C9 and may decrease the plasma concentrations of CYP2C9 substrates. TAF is not an inhibitor of CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, or UGT1A1. TAF is a weak inhibitor of CYP3A in vitro . TAF is not an inhibitor or inducer of CYP3A in vivo . 7.3 Potential for Other Drugs to Affect One or More Components of GENVOYA Elvitegravir and cobicistat, components of GENVOYA, are metabolized by CYP3A. Cobicistat is also metabolized, to a minor extent, by CYP2D6. Drugs that induce CYP3A activity are expected to increase the clearance of elvitegravir and cobicistat, resulting in decreased plasma concentration of cobicistat, elvitegravir, and TAF, which may lead to loss of therapeutic effect of GENVOYA and development of resistance (see Table 5 ). Coadministration of GENVOYA with other drugs that inhibit CYP3A may decrease the clearance and increase the plasma concentration of cobicistat. (see Table 5 ). TAF, a component of GENVOYA, is a substrate of P-gp, BCRP, OATP1B1 and OATP1B3. Drugs that inhibit P-gp and/or BCRP, such as cobicistat, may increase the absorption of TAF (see Table 13 ). However, when TAF is administered as a component of GENVOYA, its availability is increased by cobicistat and a further increase of TAF concentrations is not expected upon coadministration of an additional P-gp and/or BCRP inhibitor. Drugs that induce P-gp activity are expected to decrease the absorption of TAF, resulting in decreased plasma concentration of TAF. 7.4 Drugs Affecting Renal Function Because emtricitabine and tenofovir are primarily excreted by the kidneys by a combination of glomerular filtration and active tubular secretion, coadministration of GENVOYA with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of emtricitabine, tenofovir, and other renally eliminated drugs and this may increase the risk of adverse reactions. Some examples of drugs that are eliminated by active tubular secretion include, but are not limited to, acyclovir, cidofovir, ganciclovir, valacyclovir, valganciclovir, aminoglycosides (e.g., gentamicin), and high-dose or multiple NSAIDs [see Warnings and Precautions (5.4) ] . 7.5 Established and Other Potentially Significant Interactions Table 5 provides a listing of established or potentially clinically significant drug interactions [see Contraindications (4) ] . The drug interactions described are based on studies conducted with either GENVOYA, the components of GENVOYA (elvitegravir, cobicistat, emtricitabine, and tenofovir alafenamide) as individual agents and/or in combination, or are predicted drug interactions that may occur with GENVOYA [for magnitude of interaction, see Clinical Pharmacology (12.3) ] . The table includes potentially significant interactions but is not all inclusive. Table 5 Established and Other Potentially Significant This table is not all inclusive. Drug Interactions: Alteration in Dose or Regimen May Be Recommended Based on Drug Interaction Studies or Predicted Interaction Concomitant Drug Class: Drug Name Effect on Concentration ↑ = Increase, ↓ = Decrease Clinical Comment Alpha 1-adrenoreceptor antagonist: alfuzosin ↑ alfuzosin Coadministration with alfuzosin is contraindicated due to potential for serious and/or life-threatening reactions such as hypotension. Antiarrhythmics: e.g., amiodarone bepridil digoxin Indicates that a drug-drug interaction trial was conducted. disopyramide flecainide systemic lidocaine mexiletine propafenone quinidine ↑ antiarrhythmics ↑ digoxin Caution is warranted and therapeutic concentration monitoring, if available, is recommended for antiarrhythmics when coadministered with GENVOYA. Antibacterials: clarithromycin telithromycin ↑ clarithromycin ↑ telithromycin ↑ cobicistat Patients with CL cr greater than or equal to 60 mL/minute: No dosage adjustment of clarithromycin is required. Patients with CL cr between 50 mL/minute and 60 mL/minute: The dosage of clarithromycin should be reduced by 50%. Anticoagulants: Direct Oral Anticoagulants (DOACs) apixaban rivaroxaban betrixaban dabigatran edoxaban ↑ apixaban Due to potentially increased bleeding risk, dosing recommendations for coadministration with GENVOYA depends on the apixaban dose. Refer to apixaban dosing instructions for coadministration with strong CYP3A and P-gp inhibitors in apixaban prescribing information. ↑ rivaroxaban ↑ betrixaban ↑ dabigatran ↑ edoxaban Coadministration of rivaroxaban with GENVOYA is not recommended because it may lead to an increased bleeding risk. Due to potentially increased bleeding risk, dosing recommendations for coadministration of betrixaban, dabigatran, or edoxaban with a P-gp inhibitor such as GENVOYA depends on DOAC indication and renal function. Refer to DOAC dosing instructions for coadministration with P-gp inhibitors in DOAC prescribing information. warfarin Effect on warfarin unknown Monitor the international normalized ratio (INR) upon coadministration of warfarin with GENVOYA. Anticonvulsants: carbamazepine phenobarbital phenytoin ↓ elvitegravir ↓ cobicistat ↓ TAF Coadministration with carbamazepine, phenobarbital, or phenytoin is contraindicated due to potential for loss of therapeutic effect and development of resistance. oxcarbazepine Alternative anticonvulsants should be considered when GENVOYA is administered with oxcarbazepine. ethosuximide ↑ ethosuximide Clinical monitoring is recommended upon coadministration of ethosuximide with GENVOYA. Antidepressants: Selective Serotonin Reuptake Inhibitors (SSRIs) e.g., paroxetine Tricyclic Antidepressants (TCAs) e.g., amitriptyline desipramine imipramine nortriptyline bupropion trazodone ↑ SSRIs (except sertraline) ↑ TCAs ↑ trazodone Careful dosage titration of the antidepressant and monitoring for antidepressant response are recommended when coadministered with GENVOYA. Antifungals: itraconazole ketoconazole voriconazole ↑ elvitegravir ↑ cobicistat ↑ itraconazole ↑ ketoconazole ↑ voriconazole When administering with GENVOYA, the maximum daily dosage of ketoconazole or itraconazole should not exceed 200 mg per day. An assessment of benefit/risk ratio is recommended to justify use of voriconazole with GENVOYA. Anti-gout: colchicine ↑ colchicine GENVOYA is not recommended to be coadministered with colchicine to patients with renal or hepatic impairment. Treatment of gout-flares – coadministration of colchicine in patients receiving GENVOYA: 0.6 mg (1 tablet) × 1 dose, followed by 0.3 mg (half tablet) 1 hour later. Treatment course to be repeated no earlier than 3 days. Prophylaxis of gout-flares – coadministration of colchicine in patients receiving GENVOYA: If the original regimen was 0.6 mg twice a day, the regimen should be adjusted to 0.3 mg once a day. If the original regimen was 0.6 mg once a day, the regimen should be adjusted to 0.3 mg once every other day. Treatment of familial Mediterranean fever – coadministration of colchicine in patients receiving GENVOYA: Maximum daily dosage of 0.6 mg (may be given as 0.3 mg twice a day). Antimycobacterial: rifampin ↓ elvitegravir ↓ cobicistat ↓ TAF Coadministration with rifampin is contraindicated due to potential for loss of therapeutic effect and development of resistance. rifabutin rifapentine Coadministration of GENVOYA with rifabutin or rifapentine is not recommended. Antiplatelets: ticagrelor ↑ ticagrelor Coadminstration with ticagrelor is not recommended. clopidogrel ↓ clopidogrel active metabolite Coadministration with clopidogrel is not recommended due to protential reduction of the antiplatelet activity of clopidogrel. Antipsychotics: lurasidone ↑ lurasidone Coadministration with lurasidone is contraindicated due to potential for serious and/or life-threatening reactions. pimozide ↑ pimozide Coadministration with pimozide is contraindicated due to potential for serious and/or life-threatening reactions such as cardiac arrhythmias. quetiapine ↑ quetiapine Initiation of GENVOYA in patients taking quetiapine: Consider alternative antiretroviral therapy to avoid increases in quetiapine exposure. If coadministration is necessary, reduce the quetiapine dose to 1/6 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 GENVOYA: Refer to the quetiapine prescribing information for initial dosing and titration of quetiapine. Other antipsychotics e.g., perphenazine risperidone thioridazine ↑ antipsychotic A decrease in dose of the antipsychotics that are metabolized by CYP3A or CYP2D6 may be needed when coadministered with GENVOYA. Beta-Blockers: e.g., metoprolol timolol ↑ beta-blockers Clinical monitoring is recommended and a dosage decrease of the beta blocker may be necessary when these agents are coadministered with GENVOYA. Calcium Channel Blockers: e.g., amlodipine diltiazem felodipine nicardipine nifedipine verapamil ↑ calcium channel blockers Caution is warranted and clinical monitoring is recommended upon coadministration of calcium channel blockers with GENVOYA. Corticosteroids: e.g., betamethasone budesonide ciclesonide dexamethasone fluticasone methylprednisolone mometasone prednisone triamcinolone ↓ elvitegravir ↓ cobicistat ↑ corticosteroids Coadministration with oral dexamethasone or other systemic corticosteroids that induce CYP3A may result in loss of therapeutic effect and development of resistance to elvitegravir. Consider alternative corticosteroids. Coadministration with corticosteroids (all routes of administration) whose exposures are significantly increased by strong CYP3A inhibitors can increase the risk for Cushing's syndrome and adrenal suppression. Alternative corticosteroids including beclomethasone and prednisolone (whose PK and/or PD are less affected by strong CYP3A inhibitors relative to other studied steroids) should be considered, particularly for long-term use. Endothelin Receptor Antagonists: bosentan ↑ bosentan Coadministration of bosentan in patients on GENVOYA: In patients who have been receiving GENVOYA for at least 10 days, start bosentan at 62.5 mg once daily or every other day based upon individual tolerability. Coadministration of GENVOYA in patients on bosentan: Discontinue use of bosentan at least 36 hours prior to initiation of GENVOYA. After at least 10 days following the initiation of GENVOYA, resume bosentan at 62.5 mg once daily or every other day based upon individual tolerability. Ergot Derivatives: dihydroergotamine ergotamine methylergonovine ↑ ergot derivatives Coadministration is contraindicated due to potential for serious and/or life-threatening reactions such as acute ergot toxicity characterized by peripheral vasospasm and ischemia of the extremities and other tissues [see Contraindications (4) ] . Herbal Products: St. John's wort (Hypericum perforatum) ↓ elvitegravir ↓ cobicistat ↓ TAF Coadministration is contraindicated due to potential for loss of therapeutic effect and development of resistance . Hormonal Contraceptives: drospirenone/ethinyl estradiol levonorgestrel norgestimate/ethinyl estradiol ↑ drospirenone ↑ norgestimate ↑ levonorgestrel ↓ ethinyl estradiol Additional or alternative non-hormonal forms of contraception should be considered when estrogen based contraceptives are coadministered with GENVOYA. Plasma concentrations of drospirenone may be increased when coadministered with cobicistat-containing products. Clinical monitoring is recommended due to the potential for hyperkalemia. The effects of increases in the concentration of the progestational component norgestimate are not fully known and can include increased risk of insulin resistance, dyslipidemia, acne, and venous thrombosis. The potential risks and benefits associated with coadministration of norgestimate/ethinyl estradiol with GENVOYA should be considered, particularly in patients who have risk factors for these events. The effect of GENVOYA on other hormonal contraceptives (e.g., contraceptive patch, contraceptive vaginal ring, or injectable contraceptives) or oral contraceptives containing progestogens other than drospirenone, levonorgestrel, or norgestimate has not been studied; therefore, alternative (non-hormonal) methods of contraception can be considered. Immuno-suppressants: e.g., cyclosporine (CsA) sirolimus tacrolimus ↑ immuno-suppressants ↑ elvitegravir (with CsA) ↑ cobicistat (with CsA) Therapeutic monitoring of the immunosuppressive agents is recommended upon coadministration with GENVOYA. Monitor for adverse events associated with GENVOYA when coadministered with cyclosporine. Lipid-modifying Agents: HMG-CoA Reductase Inhibitors: lovastatin simvastatin ↑ lovastatin ↑ simvastatin Coadministration with lovastatin or simvastatin is contraindicated due to potential for serious reactions such as myopathy including rhabdomyolysis. atorvastatin ↑ atorvastatin Initiate atorvastatin with the lowest starting dose of atorvastatin and titrate carefully while monitoring for safety (e.g., myopathy). Do not exceed a dosage of atorvastatin 20 mg daily. Other Lipid-modifying Agents: lomitapide ↑ lomitapide Coadministration with lomitapide is contraindicated due to potential for markedly increased transaminases. Narcotic Analgesics: buprenorphine/ naloxone ↑ buprenorphine ↑ norbuprenorphine ↓ naloxone No dosage adjustment of buprenorphine/naloxone is required upon coadministration with GENVOYA. Patients should be closely monitored for sedation and cognitive effects. fentanyl ↑ fentanyl Careful monitoring of therapeutic and adverse effects of fentanyl (including potentially fatal respiratory depression) is recommended with coadministration. tramadol ↑ tramadol A dose decrease may be needed for tramadol with concomitant use. Inhaled Beta Agonist: salmeterol ↑ salmeterol Coadministration of salmeterol and GENVOYA is not recommended. Coadministration of salmeterol with GENVOYA may result in increased risk of cardiovascular adverse events associated with salmeterol, including QT prolongation, palpitations, and sinus tachycardia. Medications or Oral Supplements Containing Polyvalent Cations (e.g., Mg, Al, Ca, Fe, Zn): calcium or iron supplements, including multivitamins cation-containing antacids or laxatives sucralfate buffered medications ↓ elvitegravir Separate GENVOYA and administration of medications, antacids, or oral supplements containing polyvalent cations by at least 2 hours. Phosphodiesterase-5 (PDE5) Inhibitors: sildenafil tadalafil vardenafil ↑ PDE5 inhibitors Use of PDE-5 inhibitors for pulmonary arterial hypertension (PAH): Coadministration of sildenafil with GENVOYA is contraindicated when used for treatment of PAH, due to potential for PDE-5 inhibitor associated adverse reactions, including hypotension, syncope, visual disturbances, and priapism. The following dose adjustments are recommended for the use of tadalafil with GENVOYA: Coadministration of tadalafil in patients on GENVOYA: In patients receiving GENVOYA for at least 1 week, start tadalafil at 20 mg once daily. Increase tadalafil dose to 40 mg once daily based upon individual tolerability. Coadministration of GENVOYA in patients on tadalafil: Avoid use of tadalafil during the initiation of GENVOYA. Stop tadalafil at least 24 hours prior to starting GENVOYA. After at least one week following initiation of GENVOYA, resume tadalafil at 20 mg once daily. Increase tadalafil dose to 40 mg once daily based upon individual tolerability. Use of PDE-5 inhibitors for erectile dysfunction: Sildenafil at a single dose not exceeding 25 mg in 48 hours, vardenafil at a single dose not exceeding 2.5 mg in 72 hours, or tadalafil at a single dose not exceeding 10 mg in 72 hours can be used with increased monitoring for PDE-5 inhibitor associated with adverse events. Sedative/hypnotic: midazolam (oral) triazolam ↑ midazolam ↑ triazolam Coadministration with triazolam or orally administered midazolam is contraindicated due to potential for serious and/or life-threatening reactions such as prolonged or increased sedation or respiratory depression. Other benzodiazepines: e.g., parenterally administered midazolam clorazepate diazepam estazolam flurazepam ↑ sedatives/hypnotics Triazolam and orally administered midazolam are extensively metabolized by CYP3A. Coadministration of triazolam or orally administered midazolam with GENVOYA may cause large increases in the concentrations of these benzodiazepines. Coadministration of parenteral midazolam with GENVOYA should be done in a setting that ensures close clinical monitoring and appropriate medical management in case of respiratory depression and/or prolonged sedation. Dosage reduction for midazolam should be considered, especially if more than a single dose of midazolam is administered. buspirone zolpidem With other sedative/hypnotics, dose reduction may be necessary and clinical monitoring is recommended. 7.6 Drugs without Clinically Significant Interactions with GENVOYA Based on drug interaction studies conducted with the components of GENVOYA, no clinically significant drug interactions have been observed or are expected when GENVOYA is combined with the following drugs: famciclovir, famotidine, ledipasvir, methadone, omeprazole, prasugrel (active metabolite), sertraline, sofosbuvir, velpatasvir, and voxilaprevir. Drug Interactions GENVOYA may interact with many drugs; therefore, advise patients to report to their healthcare provider the use of any other prescription or non-prescription medication or herbal products including St. John's wort [see Contraindications (4) and Drug Interactions (7) ] .

6 ADVERSE REACTIONS The following adverse drug reactions are discussed in other sections of the labeling: Severe Acute Exacerbations of Hepatitis B [see Warnings and Precautions (5.1) ] Immune Reconstitution Syndrome [see Warnings and Precautions (5.3) ] New Onset or Worsening Renal Impairment [see Warnings and Precautions (5.4) ] Lactic Acidosis/Severe Hepatomegaly with Steatosis [see Warnings and Precautions (5.5) ] Most common adverse reaction (incidence greater than or equal to 10%, all grades) is nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Gilead Sciences, Inc. at 1-800-GILEAD-5 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Clinical Trials in Treatment-Naïve Adults The primary safety assessment of GENVOYA was based on Week 144 pooled data from 1,733 subjects in two randomized, double-blind, active-controlled trials, Study 104 and Study 111, in antiretroviral treatment-naïve HIV-1 infected adult subjects. A total of 866 subjects received one tablet of GENVOYA once daily [see Clinical Studies (14.2) ] . The most common adverse reaction (all Grades) reported in at least 10% of subjects in the GENVOYA group was nausea. The proportion of subjects who discontinued treatment with GENVOYA or STRIBILD ® due to adverse events, regardless of severity, was 1% and 2%, respectively. Table 1 displays the frequency of adverse reactions (all Grades) greater than or equal to 5% in the GENVOYA group. Table 1 Adverse Reactions Frequencies of adverse reactions are based on all adverse events attributed to study drugs by the investigator. (All Grades) Reported in ≥ 5% of HIV-1 Infected Treatment-Naïve Adults Receiving GENVOYA in Studies 104 and 111 (Week 144 analysis) GENVOYA N=866 STRIBILD N=867 Nausea 11% 13% Diarrhea 7% 9% Headache 6% 5% Fatigue 5% 4% The majority of events presented in Table 1 occurred at severity Grade 1. Clinical Trials in Virologically Suppressed Adults The safety of GENVOYA in virologically-suppressed adults was based on Week 96 data from 959 subjects in a randomized, open-label, active-controlled trial (Study 109) in which virologically-suppressed subjects were switched from a TDF-containing combination regimen to GENVOYA. Overall, the safety profile of GENVOYA in subjects in this study was similar to that of treatment-naïve subjects [see Clinical Studies (14.3) ] . Additional adverse reactions observed with GENVOYA in Study 109 included suicidal ideation, suicidal behavior, and suicide attempt (<1% combined); all of these events were serious and all occurred in subjects with a preexisting history of depression or psychiatric illness. Clinical Trials in Adult Subjects with Renal Impairment In an open-label trial (Study 112), 248 HIV-1 infected subjects with estimated creatinine clearance between 30 and 69 mL per minute (by Cockcroft-Gault method) were treated with GENVOYA for a median duration of 144 weeks. Of these subjects, 65% had previously been on a stable TDF-containing regimen. A total of 5 subjects permanently discontinued GENVOYA due to the development of renal adverse events through Week 96. Three of these five were among the 80 subjects with baseline estimated creatinine clearance of less than 50 mL/min and two subjects were among the 162 subjects with baseline estimated creatinine clearance of greater than or equal to 50 mL/min. There were no further renal discontinuations between Weeks 96 and 144. Overall, renally impaired subjects receiving GENVOYA in this study had a mean serum creatinine of 1.5 mg/dL at baseline and 1.4 mg/dL at Week 144. Otherwise, the safety profile of GENVOYA in subjects in this study was similar to that of subjects with normal renal function. Virologically-Suppressed Adults with End Stage Renal Disease (ESRD) Receiving Chronic Hemodialysis The safety of GENVOYA in subjects with end stage renal disease (ESRD) (estimated creatinine clearance of less than 15 mL/min) on chronic hemodialysis was assessed in 55 subjects (Study 1825) [see Clinical Studies (14.4) ]. The most commonly reported adverse reaction (adverse event assessed as causally related by investigator and all grades) was nausea (7%). Serious adverse events were reported in 53% of subjects and the most common serious adverse events were pneumonia (13%), fluid overload (7%), hyperkalemia (7%) and osteomyelitis (7%). Overall 5% of subjects permanently discontinued treatment due to an adverse event. Renal Laboratory Tests and Renal Safety Treatment-Naïve Adults: Cobicistat (a component of GENVOYA) has been shown to increase serum creatinine due to inhibition of tubular secretion of creatinine without affecting glomerular filtration [see Clinical Pharmacology (12.2) ] . Increases in serum creatinine occurred by Week 2 of treatment and remained stable through 144 weeks. In two 144-week randomized, controlled trials in a total of 1,733 treatment-naïve adults with a median baseline estimated creatinine clearance of 115 mL per minute, mean serum creatinine increased by less than 0.1 mg per dL in the GENVOYA group and by 0.1 mg per dL in the STRIBILD group from baseline to Week 144. Virologically Suppressed Adults: In a study of 1,436 virologically-suppressed TDF-treated adults with a mean baseline estimated creatinine clearance of 112 mL per minute who were randomized to continue their treatment regimen or switch to GENVOYA, at Week 96 mean serum creatinine was similar to baseline for both those continuing baseline treatment and those switching to GENVOYA. Across these trials, renal serious adverse events or discontinuations due to renal adverse reactions were encountered in less than 1% of participants treated with GENVOYA. Bone Mineral Density Effects Treatment-Naïve Adults: In a pooled analysis of Studies 104 and 111, the effects of GENVOYA compared to STRIBILD on bone mineral density (BMD) change from baseline to Week 144 were assessed by dual-energy X-ray absorptiometry (DXA). The mean percentage change in BMD from baseline to Week 144 was −0.92% with GENVOYA compared to −2.95% with STRIBILD at the lumbar spine and −0.75% compared to −3.36% at the total hip. BMD declines of 5% or greater at the lumbar spine were experienced by 15% of GENVOYA subjects and 29% of STRIBILD subjects. BMD declines of 7% or greater at the femoral neck were experienced by 15% of GENVOYA subjects and 29% of STRIBILD subjects. The long-term clinical significance of these BMD changes is not known. Virologically Suppressed Adults: In Study 109, TDF-treated subjects were randomized to continue their TDF-based regimen or switch to GENVOYA; changes in BMD from baseline to Week 96 were assessed by DXA. Mean BMD increased in subjects who switched to GENVOYA (2.12% lumbar spine, 2.44% total hip) and decreased slightly in subjects who continued their baseline regimen (−0.09% lumbar spine, −0.46% total hip). BMD declines of 5% or greater at the lumbar spine were experienced by 2% of GENVOYA subjects and 6% of subjects who continued their TDF-based regimen. BMD declines of 7% or greater at the femoral neck were experienced by 2% of GENVOYA subjects and 7% of subjects who continued their TDF-based regimen. The long-term clinical significance of these BMD changes is not known. Laboratory Abnormalities: The frequency of laboratory abnormalities (Grades 3–4) occurring in at least 2% of subjects receiving GENVOYA in Studies 104 and 111 are presented in Table 2. Table 2 Laboratory Abnormalities (Grades 3–4) Reported in ≥ 2% of Subjects Receiving GENVOYA in Studies 104 and 111 (Week 144 analysis) Laboratory Parameter Abnormality Frequencies are based on treatment-emergent laboratory abnormalities.

With the exception of a decrease in the mean CD4+ cell count observed in cohort 2 of Study 106, the safety profile in pediatric subjects who received treatment with GENVOYA was similar to that in adults. One 13-year-old female subject developed unexplained uveitis while receiving GENVOYA that resolved and did not require discontinuation of GENVOYA. Bone Mineral Density Effects Cohort 1: Treatment-naïve adolescents (12 to less than 18 years; at least 35 kg) Among the subjects in cohort 1 receiving GENVOYA, mean BMD increased from baseline to Week 48, + 4.2% at the lumbar spine and + 1.3% for the total body less head (TBLH). Mean changes from baseline BMD Z-scores were −0.07 for lumbar spine and −0.20 for TBLH at Week 48. One GENVOYA subject had significant (at least 4%) lumbar spine BMD loss at Week 48. Cohort 2: Virologically-suppressed children (6 to less than 12 years; at least 25 kg) Among the subjects in cohort 2 receiving GENVOYA, mean BMD increased from baseline to Week 48, +3.9% at the lumbar spine and +4.2% for TBLH. Mean changes from baseline BMD Z-scores were -0.24 for lumbar spine and -0.19 for TBLH at Week 48. Six GENVOYA subjects had significant (at least 4%) lumbar spine BMD loss at Week 48; 2 subjects also had at least 4% TBLH BMD loss at Week 48. Change from Baseline in CD4+ cell counts Cohort 2: Virologically-suppressed children (6 to less than 12 years; at least 25 kg) Cohort 2 of Study 106 evaluated pediatric subjects (N=52) who were virologically-suppressed and who switched from their antiretroviral regimen to GENVOYA. Although all subjects had HIV-1 RNA < 50 copies/mL, there was a decrease from baseline in CD4+ cell count at Weeks 24 and 48. The mean baseline and mean change from baseline in CD4+ cell count and in CD4% from Week 2 to Week 48 are presented in Table 4. All subjects maintained their CD4+ cell counts above 400 cells/mm 3 [see Pediatric Use (8.4) and Clinical Studies (14.5) ].

Because these events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Skin and Subcutaneous Tissue Disorders Angioedema, urticaria, and rash Renal and Urinary Disorders Acute renal failure, acute tubular necrosis, proximal renal tubulopathy, and Fanconi syndrome

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in individuals exposed to GENVOYA during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258-4263. Risk Summary GENVOYA is not recommended during pregnancy [see Dosage and Administration (2.5) ] . A literature report evaluating the pharmacokinetics of antiretrovirals during pregnancy demonstrated substantially lower exposures of elvitegravir and cobicistat in the second and third trimesters (see Data ) . Prospective pregnancy data from the APR are not sufficient to adequately assess the risk of birth defects or miscarriage. However, elvitegravir (EVG), cobicistat (COBI), emtricitabine (FTC), and tenofovir alafenamide (TAF) use during pregnancy have been evaluated in a limited number of individuals as reported to the APR. Available data from the APR show no statistically significant difference in the overall risk of major birth defects for EVG, COBI, FTC or TAF compared with the background rate for major birth defects of 2.7% in a U.S. reference population of the Metropolitan Atlanta Congenital Defects Program (MACDP) (see Data ) . The rate of miscarriage is not reported in the APR. In the U.S. general population, the estimated background risk of miscarriage in clinically recognized pregnancies is 15-20%. In animal studies, no adverse developmental effects were observed when the components of GENVOYA were administered separately during the period of organogenesis at exposures up to 23 and 0.2 times (rat and rabbits, respectively: elvitegravir), 1.6 and 3.8 times (rats and rabbits, respectively: cobicistat), 60 and 108 times (mice and rabbits, respectively; emtricitabine) and equal to and 53 times (rats and rabbits, respectively; TAF) the exposure at the recommended daily dosage of these components in GENVOYA (see Data ) . Likewise, no adverse developmental effects were seen when elvitegravir or cobicistat was administered to rats through lactation at exposures up to 18 times or 1.2 times, respectively, the human exposure at the recommended therapeutic dose, and when emtricitabine was administered to mice through lactation at exposures up to approximately 60 times the exposure at the recommended daily dose. No adverse effects were observed in the offspring when TDF was administered through lactation at tenofovir exposures of approximately 14 times the exposure at the recommended daily dosage of GENVOYA. Data Human Data A prospective study, reported in the literature, enrolled 30 pregnant women living with HIV who were receiving elvitegravir and cobicistat-based regimens in the second or third trimesters of pregnancy and through 6 to 12 weeks postpartum to evaluate the pharmacokinetics (PK) of antiretrovirals during pregnancy. Twenty-eight women completed the study through the postpartum period. Paired pregnancy/postpartum PK data were available from 14 and 24 women for the second and third trimesters, respectively. Exposures of elvitegravir and cobicistat were substantially lower during the second and third trimesters compared to postpartum. The proportion of pregnant women who were virologically suppressed was 77% in the second trimester, 92% in the third trimester, and 76% postpartum. No correlation was observed between viral suppression and elvitegravir exposure. HIV status was also assessed for infants: 25 were uninfected, 2 had indeterminate status, and no information was available for 3 infants. Prospective reports from the APR of overall major birth defects in pregnancies exposed to the components of GENVOYA are compared with a U.S. background major birth defect rate. Methodological limitations of the APR include the use of MACDP as the external comparator group. Limitations of using an external comparator include differences in methodology and populations, as well as confounding due to the underlying disease. Elvitegravir (EVG): Based on prospective reports to the APR of over 440 exposures to EVG-containing regimens during pregnancy resulting in live births (including over 350 exposed in the first trimester and 70 exposed in the second/third trimester), the prevalence of birth defects in live births was 3.0% (95% CI: 1.5% to 5.2%) and 1.4% (95% CI: 0.0% to 7.7%) following first and second/third trimester exposure, respectively, to EVG-containing regimens. Cobicistat (COBI): Based on prospective reports to the APR of over 560 exposures to COBI-containing regimens during pregnancy resulting in live births (including over 470 exposed in the first trimester and over 80 exposed in the second/third trimester), the prevalence of birth defects in live births was 3.6% (95% CI: 2.1% to 5.7%) and 1.1% (95% CI: 0.0% to 6.2%) following first and second/third trimester, respectively, to COBI-containing regimens. Emtricitabine (FTC): Based on prospective reports to the APR of over 5,400 exposures to FTC-containing regimens during pregnancy resulting in live births (including over 3,900 exposed in the first trimester and over 1,500 exposed in the second/third trimester), the prevalence of birth defects in live births was 2.6% (95% CI: 2.2% to 3.2%) and 2.7% (95% CI: 1.9% to 3.7%) following first and second/third trimester exposure, respectively, to FTC-containing regimens. Tenofovir Alafenamide (TAF): Based on prospective reports to the APR of over 660 exposures to TAF-containing regimens during pregnancy resulting in live births (including over 520 exposed in the first trimester and over 130 exposed in the second/third trimester), the prevalence of birth defects in live births was 4.2% (95% CI: 2.6% to 6.3%) and 3.0% (95% CI: 0.8% to 7.5%) following first and second/third trimester exposure, respectively, to TAF-containing regimens. Animal Data Elvitegravir: Elvitegravir was administered orally to pregnant rats (0, 300, 1000, and 2000 mg/kg/day) and rabbits (0, 50, 150, and 450 mg/kg/day) through organogenesis (on gestation days 7 through 17 and days 7 through 19, respectively). No significant toxicological effects were observed in embryo-fetal toxicity studies performed with elvitegravir in rats at exposures (AUC) approximately 23 times and in rabbits at approximately 0.2 times the human exposures at the recommended daily dose. In a pre/postnatal developmental study, elvitegravir was administered orally to rats at doses of 0, 300, 1000, and 2000 mg/kg from gestation day 7 to day 20 of lactation. At doses of 2000 mg/kg/day of elvitegravir, neither maternal nor developmental toxicity was noted. Systemic exposures (AUC) at this dose were 18 times the human exposures at the recommended daily dose. Cobicistat: Cobicistat was administered orally to pregnant rats at doses of 0, 25, 50, 125 mg/kg/day on gestation day 6 to 17. Increases in post-implantation loss and decreased fetal weights were observed at a maternal toxic dose of 125 mg/kg/day. No malformations were noted at doses up to 125 mg/kg/day. Systemic exposures (AUC) at 50 mg/kg/day in pregnant females were 1.6 times higher than human exposures at the recommended daily dose. In pregnant rabbits, cobicistat was administered orally at doses of 0, 20, 50, and 100 mg/kg/day during gestation days 7 to 20. No maternal or embryo/fetal effects were noted at the highest dose of 100 mg/kg/day. Systemic exposures (AUC) at 100 mg/kg/day were 3.8 times higher than human exposures at the recommended daily dose. In a pre/postnatal developmental study in rats, cobicistat was administered orally at doses of 0, 10, 30, and 75 mg/kg from gestation day 6 to postnatal day 20, 21, or 22. At doses of 75 mg/kg/day of cobicistat, neither maternal nor developmental toxicity was noted. Systemic exposures (AUC) at this dose were 1.2 times the human exposures at the recommended daily dose. Emtricitabine: Emtricitabine was administered orally to pregnant mice (250, 500, or 1000 mg/kg/day) and rabbits (100, 300, or 1000 mg/kg/day) through organogenesis (on gestation days 6 through 15, and 7 through 19, respectively). No significant toxicological effects were observed in embryo-fetal toxicity studies performed with emtricitabine in mice at exposures (AUC) approximately 60 times higher and in rabbits at approximately 108 times higher than human exposures at the recommended daily dose. In a pre/postnatal development study with emtricitabine, mice were administered doses up to 1000 mg/kg/day; no significant adverse effects directly related to drug were observed in the offspring exposed daily from before birth ( in utero ) through sexual maturity at daily exposures (AUC) of approximately 60 times higher than human exposures at the recommended daily dose. Tenofovir Alafenamide (TAF): TAF was administered orally to pregnant rats (25, 100, or 250 mg/kg/day) and rabbits (10, 30, or 100 mg/kg/day) through organogenesis (on gestation days 6 through 17, and 7 through 20, respectively). No adverse embryo-fetal effects were observed in rats and rabbits at TAF exposures similar to (rats) and approximately 53 (rabbits) times higher than the exposure in humans at the recommended daily dose of GENVOYA. TAF is rapidly converted to tenofovir; the observed tenofovir exposure in rats and rabbits were 59 (rats) and 93 (rabbits) times higher than human tenofovir exposures at the recommended daily doses. Since TAF is rapidly converted to tenofovir and lower tenofovir exposures in rats and mice were observed after TAF administration compared to TDF administration, a pre/postnatal development study in rats was conducted only with TDF. Doses up to 600 mg/kg/day were administered through lactation; no adverse effects were observed in the offspring on gestation day 7 [and lactation day 20] at tenofovir exposures of approximately 14 [21] times higher than the exposures in humans at the recommended daily dose of GENVOYA. Pregnancy Advise patients that GENVOYA is not recommended during pregnancy and to alert their healthcare provider if they become pregnant while taking GENVOYA [see Dosage and Administration (2.5) and Use in Specific Populations (8.1) ]. Inform patients that there is an antiretroviral pregnancy registry to monitor fetal outcomes of pregnant individuals exposed to GENVOYA [see Use in Specific Populations (8.1) ] .
