    • What Is Dolutegravir Sodium And Rilpivirine Hydrochloride Used For?

    1 INDICATIONS AND USAGE JULUCA is indicated as a complete regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in adults to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies/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 JULUCA. JULUCA, a two-drug combination of dolutegravir, an HIV-1 integrase strand transfer inhibitor (INSTI), and rilpivirine, an HIV-1 non-nucleoside reverse transcriptase inhibitor (NNRTI), is indicated as a complete regimen for the treatment of HIV-1 infection in adults to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies/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 JULUCA.

    • Side Effects (Adverse Reactions)

    6 ADVERSE REACTIONS The following adverse reactions are described below and in other sections of the labeling:

  • Skin and hypersensitivity reactions [see Warnings and Precautions ( 5.1 )].
  • Hepatotoxicity [see Warnings and Precautions ( 5.2 )].
  • Depressive disorders [see Warnings and Precautions ( 5.3 )]. The most common adverse reactions (all grades) observed in at least 2% of subjects were diarrhea, headache, and nausea. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact ViiV Healthcare at 1-877-844-8872 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety assessment of JULUCA is based on the pooled primary Week 48 analyses of data from 2 identical, international, multicenter, open-label trials, SWORD-1 and SWORD-2, including additional follow up through Week 148. A total of 1,024 adult HIV-1-infected subjects who were on a stable suppressive antiretroviral regimen (containing 2 nucleoside reverse transcriptase inhibitors [NRTIs] plus either an integrase strand transfer inhibitor [INSTI], a non-nucleoside reverse transcriptase inhibitor [NNRTI], or a protease inhibitor [PI]) for at least 6 months with no history of treatment failure and no known substitutions associated with resistance to dolutegravir or rilpivirine, were randomized and received treatment. Subjects were randomized 1:1 to continue their current antiretroviral regimen or be switched to dolutegravir plus rilpivirine administered once daily. Subjects originally assigned to continue their current antiretroviral regimen and who remained virologically suppressed at Week 48 switched to dolutegravir plus rilpivirine at Week 52. In the pooled analyses, the proportion of subjects who discontinued treatment due to an adverse event through Week 48 was 4% in subjects receiving dolutegravir plus rilpivirine once daily and less than 1% in subjects who remained on their current antiretroviral regimen. The most common adverse events leading to discontinuation through Week 48 were psychiatric disorders: 2% of subjects receiving dolutegravir plus rilpivirine and less than 1% on the current antiretroviral regimen. In the pooled analyses, the proportion of subjects receiving dolutegravir plus rilpivirine who discontinued treatment due to an adverse event through Week 148 was 8%. The most common adverse reactions (ARs) (all grades) reported in at least 2% of subjects in the Week 48 pooled analyses from SWORD-1 and SWORD-2 are provided in Table 2 . Table 2. Adverse Reactions (Grades 1 to 4) Reported in at Least 2% of Virologically Suppressed Subjects with HIV-1 Infection in SWORD-1 and SWORD-2 Trials (Week 48 Pooled Analyses) Adverse Reaction Dolutegravir plus Rilpivirine (n = 513) Current Antiretroviral Regimen (n = 511) Diarrhea 2% <1% Headache 2% 0 In the Week 148 pooled analyses, the only adverse reaction (all grades) occurring in at least 2% of subjects who received dolutegravir plus rilpivirine and that was not observed during the Week 48 analyses was nausea (2%). Less Common Adverse Reactions The following ARs occurred in less than 2% of subjects receiving dolutegravir plus rilpivirine or are from studies described in the prescribing information of the individual components, TIVICAY (dolutegravir) and EDURANT (rilpivirine). Some events have been included because of their seriousness and assessment of potential causal relationship. General Disorders: Fatigue. Gastrointestinal Disorders: Abdominal pain, abdominal discomfort, flatulence, nausea, upper abdominal pain, vomiting. Hepatobiliary Disorders: Cholecystitis, cholelithiasis, hepatitis. Immune System Disorders: Immune reconstitution syndrome. Metabolism and Nutrition Disorders: Decreased appetite. Musculoskeletal...

    • 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...

    • 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 )

    • Pregnancy and Breastfeeding

    8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in individuals exposed to JULUCA during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258-4263. Risk Summary Data from two, ongoing birth outcome surveillance studies in Botswana and Eswatini which together include over 14,000 individuals evaluated during pregnancy show similar prevalence of neural tube defects among infants born to individuals taking dolutegravir at the time of conception compared to those born to individuals taking non-dolutegravir-containing regimens at conception or infants born to HIV-negative individuals (see Data). There are insufficient human data on the use of JULUCA during pregnancy to definitively assess a drug-associated risk for birth defects and miscarriage. However, available human data from the APR with the individual components of JULUCA do not indicate an increased risk of birth defects (see Data) . The background risk for major birth defects for the indicated population is unknown. In the U.S. general population, the estimated background rate for major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. In animal reproduction studies, no evidence of adverse developmental outcomes (including neural tube defects) was observed with the components of JULUCA at systemic exposures (AUC) to dolutegravir less than (rabbits) and 38 times (rats) and exposures to rilpivirine 15 (rats) and 70 (rabbits) times the exposure at the recommended human dose (RHD) of JULUCA (see Data) . Data Human Data: Dolutegravir: Observational studies: The first interim analysis from an ongoing birth outcome surveillance study in Botswana identified an association between dolutegravir and an increased risk of neural tube defects when dolutegravir was administered at the time of conception and in early...

    Overdosage

    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.
