Brand names: Juluca
Warnings
5 WARNINGS AND PRECAUTIONS • Severe skin and hypersensitivity reactions characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury, have been reported with the individual components. Discontinue JULUCA immediately if signs or symptoms of severe skin or hypersensitivity reactions develop, as a delay in stopping treatment may result in a life-threatening reaction. ( 5.1 ) • Hepatotoxicity has been reported in patients receiving a dolutegravir- or rilpivirine-containing regimen. Monitoring for hepatotoxicity is recommended. ( 5.2 ) • Depressive disorders have been reported with the use of rilpivirine- or dolutegravir-containing regimens. Immediate medical evaluation is recommended for severe depressive symptoms. ( 5.3 , 6.1 ) 5.1 Skin and Hypersensitivity Reactions Hypersensitivity reactions have been reported with dolutegravir and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury. These events were reported in less than 1% of subjects receiving dolutegravir in Phase 3 clinical trials. Severe skin and hypersensitivity reactions have been reported during postmarketing experience, including cases of Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS), with rilpivirine-containing regimens. While some skin reactions were accompanied by constitutional symptoms such as fever, other skin reactions were associated with organ dysfunctions, including elevations in hepatic serum biochemistries. During the Phase 3 clinical trials of rilpivirine, treatment-related rashes with at least Grade 2 severity were reported in 3% of subjects. No Grade 4 rash was reported [see Adverse Reactions ( 6.2 )] . Discontinue JULUCA immediately if signs or symptoms of severe skin or hypersensitivity reactions develop (including, but not limited to, severe rash or rash accompanied by fever, general malaise, fatigue, muscle or joint aches, blisters or peeling of the skin, mucosal involvement [oral blisters or lesions], conjunctivitis, facial edema, hepatitis, eosinophilia, angioedema, difficulty breathing). Clinical status, including laboratory parameters with liver aminotransferases, should be monitored and appropriate therapy initiated. Delay in stopping treatment with JULUCA after the onset of hypersensitivity may result in a life-threatening reaction [see Contraindications ( 4 )] . 5.2 Hepatotoxicity Hepatic adverse events have been reported in patients receiving a dolutegravir- or rilpivirine-containing regimen [see Adverse Reactions ( 6.1 )] . Patients with underlying hepatitis B or C or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations. Additionally, in some patients receiving dolutegravir-containing regimens, the elevations in transaminases were consistent with immune reconstitution syndrome or hepatitis B reactivation particularly in the setting where anti-hepatitis therapy was withdrawn. Cases of hepatic toxicity, including elevated serum liver biochemistries and hepatitis, have also been reported in patients receiving a dolutegravir- or rilpivirine-containing regimen who had no pre-existing hepatic disease or other identifiable risk factors. Drug-induced liver injury leading to acute liver failure has been reported with dolutegravir-containing products, including liver transplant with TRIUMEQ (abacavir, dolutegravir, and lamivudine). Monitoring for hepatotoxicity is recommended. 5.3 Depressive Disorders Depressive disorders (including depressed mood, depression, dysphoria, major depression, mood altered, negative thoughts, suicide attempt, and suicidal ideation) have been reported with rilpivirine [see Adverse Reactions ( 6.1 )] . For information regarding depressive disorders reported in patients taking dolutegravir, [see Adverse Reactions ( 6.1 )] . Promptly evaluate patients with severe depressive symptoms to assess whether the symptoms are related to JULUCA and to determine whether the risks of continued therapy outweigh the benefits. 5.4 Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions The concomitant use of JULUCA and other drugs may result in known or potentially significant drug interactions, some of which may lead to [see Contraindications ( 4 ), Drug Interactions ( 7.4 )] : • Loss of therapeutic effect of JULUCA and possible development of resistance. • Possible clinically significant adverse reactions from greater exposures of concomitant drugs. In healthy subjects, 75 mg once daily of rilpivirine (3 times the dose in JULUCA) and 300 mg once daily (12 times the dose in JULUCA) have been shown to prolong the QTc interval of the electrocardiogram [see Drug Interactions ( 7.3 ), Clinical Pharmacology ( 12.2 )] . Consider alternatives to JULUCA when coadministered with a drug with a known risk of Torsade de Pointes. See Table 4 for steps to prevent or manage these possible and known significant drug interactions, including dosing recommendations. Consider the potential for drug interactions prior to and during therapy with JULUCA; review concomitant medications during therapy with JULUCA; and monitor for the adverse reactions associated with the concomitant drugs.
Contraindications
4 CONTRAINDICATIONS JULUCA is contraindicated in patients: • with previous hypersensitivity reaction to dolutegravir or rilpivirine [see Warnings and Precautions ( 5.1 )] . • receiving dofetilide due to the potential for increased dofetilide plasma concentrations and the risk for serious and/or life-threatening events [see Drug Interactions ( 7 )] . • receiving other coadministered drugs in Table 1 that significantly decrease rilpivirine plasma concentrations [see Drug Interactions ( 7 ), Clinical Pharmacology ( 12.3 )] . Table 1. Drugs That Are Contraindicated with JULUCA Drug Class Contraindicated Drugs in Class Clinical Comment Antiarrhythmic Dofetilide Potential for serious and/or life-threatening events due to the potential for increased dofetilide plasma concentrations. Anticonvulsants Carbamazepine Oxcarbazepine Phenobarbital Phenytoin Potential for significant decreases in rilpivirine plasma concentrations due to cytochrome P450 (CYP)3A enzyme induction, which may result in loss of virologic response. Antimycobacterials Rifampin Rifapentine Glucocorticoid (systemic) Dexamethasone (more than a single-dose treatment) Herbal Products St John’s wort ( Hypericum perforatum ) Proton Pump Inhibitors e.g., Esomeprazole Lansoprazole Omeprazole Pantoprazole Rabeprazole Potential for significant decreases in rilpivirine plasma concentrations due to gastric pH increase, which may result in loss of virologic response. • Previous hypersensitivity reaction to dolutegravir or rilpivirine. ( 4 ) • Coadministration with dofetilide. ( 4 ) • Coadministration with drugs where significant decreases in rilpivirine plasma concentrations may occur, which may result in loss of virologic response. ( 4 )
Overdose
10 OVERDOSAGE There is no known specific treatment for overdose with JULUCA. If overdose occurs, the patient should be monitored and standard supportive treatment applied as required, including monitoring of vital signs and ECG (QT interval) as well as observation of the clinical status of the patient. As both dolutegravir and rilpivirine are highly bound to plasma proteins, it is unlikely that either would be significantly removed by dialysis.
Drug interactions
7 DRUG INTERACTIONS • Because JULUCA is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended. ( 7.1 ) • Refer to the full prescribing information for important drug interactions with JULUCA. ( 4 , 5.4 , 7 ) • Drugs that induce or inhibit cytochrome P450 (CYP)3A4 or uridine diphosphate glucuronosyltransferase (UGT)1A1 may affect the plasma concentrations of the components of JULUCA. ( 7.3 ) • Drugs that increase gastric pH or containing polyvalent cations may decrease plasma concentrations of the components of JULUCA. ( 4 , 7.3 , 7.4 ) • Consider alternatives to prescribing JULUCA with drugs with a known risk of Torsade de Pointes. ( 7.3 ) 7.1 Concomitant Use with Other Antiretroviral Medicines Because JULUCA is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended [see Indications and Usage ( 1 )] . Information regarding potential drug-drug interactions with other antiretroviral medications is not provided [see Contraindications ( 4 ), Warnings and Precautions ( 5.4 ), Clinical Pharmacology ( 12.3 )] . 7.2 Potential for JULUCA to Affect Other Drugs Dolutegravir, a component of JULUCA, inhibits the renal organic cation transporters (OCT)2 and multidrug and toxin extrusion transporter (MATE)1, thus it may increase plasma concentrations of drugs eliminated via OCT2 or MATE1 such as dofetilide, dalfampridine, and metformin [see Contraindications ( 4 ), Drug Interactions ( 7.4 )] . 7.3 Potential for Other Drugs to Affect the Components of JULUCA Dolutegravir Dolutegravir is metabolized by uridine diphosphate (UDP)-glucuronosyl transferase (UGT)1A1 with some contribution from cytochrome P450 (CYP)3A. Dolutegravir is also a substrate of UGT1A3, UGT1A9, breast cancer resistance protein (BCRP), and P-glycoprotein (P-gp) in vitro. Drugs that induce those enzymes and transporters may decrease dolutegravir plasma concentrations and reduce the therapeutic effect of dolutegravir [see Drug Interactions ( 7.4 )] . Coadministration of dolutegravir and other drugs that inhibit these enzymes may increase dolutegravir plasma concentrations. Coadministration of dolutegravir with polyvalent cation-containing products may lead to decreased absorption of dolutegravir [see Drug Interactions ( 7.4 )] . Rilpivirine Rilpivirine is primarily metabolized by CYP3A, and drugs that induce or inhibit CYP3A may affect the clearance of rilpivirine. Coadministration of JULUCA and drugs that induce CYP3A may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs [see Contraindications ( 4 ), Drug Interactions ( 7.4 )] . Coadministration of JULUCA and drugs that inhibit CYP3A may result in increased plasma concentrations of rilpivirine. Coadministration of JULUCA with drugs that increase gastric pH may result in decreased plasma concentrations of rilpivirine and loss of virologic response and possible resistance to rilpivirine or to the class of NNRTIs [see Contraindications ( 4 ), Drug Interactions ( 7.4 ), Clinical Pharmacology ( 12.3 )] . QT-Prolonging Drugs: In healthy subjects, 75 mg once daily of rilpivirine (3 times the dose in JULUCA) and 300 mg once daily (12 times the dose in JULUCA) have been shown to prolong the QTc interval of the electrocardiogram [see Clinical Pharmacology ( 12.2 )] . Consider alternatives to JULUCA when coadministered with a drug with a known risk of Torsade de Pointes. 7.4 Established and Other Potentially Significant Drug Interactions Information regarding potential drug interactions with dolutegravir and rilpivirine are provided in Table 4 . These recommendations are based on either drug interaction trials of individual components or predicted interactions due to the expected magnitude of interaction and potential for serious adverse events or loss of efficacy [see Contraindications ( 4 ), Warnings and Precautions ( 5.4 ), Clinical Pharmacology ( 12.3 )] .
