Indications and Usage:
TRIUMEQ is indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection.
Limitations of Use:
- TRIUMEQ alone is not recommended in patients with:
- Current or past history of resistance to any components of TRIUMEQ
- Resistance-associated integrase substitutions or clinically suspected integrase strand transfer inhibitor (INSTI) resistance because the dose of dolutegravir in TRIUMEQ is insufficient in these subpopulations. See full prescribing information for dolutegravir
Important Safety Information:
BOXED WARNING: HYPERSENSITIVITY REACTIONS, LACTIC ACIDOSIS AND SEVERE HEPATOMEGALY, and EXACERBATIONS OF HEPATITIS B VIRUS (HBV): See full Prescribing Information for complete boxed warning
- Serious and sometimes fatal hypersensitivity reactions have occurred with abacavir-containing products
- Hypersensitivity to abacavir is a multi-organ clinical syndrome
- Patients who carry the HLA-B*5701allele are at a higher risk of experiencing a hypersensitivity reaction to abacavir, although hypersensitivity reactions have occurred in patients who do not carry the HLA-B*5701allele
- TRIUMEQ is contraindicated in patients with a prior hypersensitivity reaction to abacavir and in HLA-B*5701-positivepatients. All patients should be screened for the HLA-B*5701allele prior to initiating therapy or reinitiation of therapy with TRIUMEQ, unless patients have a previously documented HLA-B*5701 allele assessment
- Discontinue TRIUMEQ as soon as hypersensitivity reaction is suspected. Regardless of HLA-B*5701status, permanently discontinue TRIUMEQ if hypersensitivity cannot be ruled out, even when other diagnoses are possible
- Following a hypersensitivity reaction to TRIUMEQ, NEVER restart TRIUMEQ or any other abacavir-containing product
Lactic Acidosis and Severe Hepatomegaly with Steatosis:
- Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues
Exacerbations of Hepatitis B:
- Severe acute exacerbations of HBV have been reported in patients who are co-infected with HBV and HIV-1 and have discontinued lamivudine, a component of TRIUMEQ. Monitor hepatic function closely in these patients and, if appropriate, initiate anti-hepatitis B treatment
TRIUMEQ is contraindicated in patients:
- who have the HLA-B*5701 allele
- with prior hypersensitivity reaction to abacavir, dolutegravir, or lamivudine
- receiving dofetilide (antiarrhythmic)
- with moderate or severe hepatic impairment
WARNINGS AND PRECAUTIONS
Hypersensitivity Reactions to Dolutegravir:
- Hypersensitivity reactions have been reported and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury. The events were reported in <1% of subjects receiving TIVICAY® in Phase 3 clinical trials
- Clinically, it is not possible to determine whether a hypersensitivity reaction with TRIUMEQ would be caused by abacavir or dolutegravir. Discontinue TRIUMEQ and other suspect agents immediately if signs or symptoms of hypersensitivity reaction develop
- Patients with underlying hepatitis B or C may be at increased risk for worsening or development of transaminase elevations with use of TRIUMEQ. In some cases 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, hepatitis, and acute liver failure, have also been reported in patients receiving a dolutegravir-containing regimen who had no pre-existing hepatic disease or other identifiable risk factors. Drug-induced liver injury leading to liver transplant has been reported with TRIUMEQ
- Monitoring for hepatotoxicity is recommended
Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions:
The concomitant use of TRIUMEQ and other drugs may result in known or potentially significant drug interactions (see Contraindications and Drug Interactions).
Use with Interferon- and Ribavirin-based Regimens:
Hepatic decompensation, some fatal, has occurred in HIV-1/hepatitis C virus (HCV) co-infected patients receiving combination antiretroviral therapy and interferon alfa with or without ribavirin. Patients receiving interferon alfa, with or without ribavirin, and TRIUMEQ should be closely monitored.
Immune Reconstitution Syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported.
Fat Redistribution or accumulation has been observed in patients receiving antiretroviral therapy.
Myocardial Infarction (MI):
- An observational study showed an increase in MI with abacavir; a sponsor-conducted, pooled analysis did not show increased risk. In totality, the available data are inconclusive
- The underlying risk of coronary heart disease should be considered when prescribing antiretroviral therapies, including abacavir, and action taken to minimize all modifiable risk factors (eg, hypertension, hyperlipidemia, diabetes mellitus, smoking)
Use with Certain Antiretroviral Products:
TRIUMEQ should not be administered concomitantly with other products containing abacavir or lamivudine.
- The most commonly reported (≥2%) adverse reactions of at least moderate intensity in treatment-naïve adults receiving TRIUMEQ were insomnia (3%), headache (2%), and fatigue (2%)
- Coadministration of TRIUMEQ with certain inducers of UGT1A and/or CYP3A may reduce plasma concentrations of dolutegravir. Consult the full Prescribing Information for TRIUMEQ for more information
- Administer TRIUMEQ 2 hours before or 6 hours after taking polyvalent cation-containing antacids or laxatives, sucralfate, oral supplements containing iron or calcium, or buffered medications. Alternatively, TRIUMEQ and supplements containing calcium or iron can be taken with food
USE IN SPECIFIC POPULATIONS
- Pregnancy Category C. TRIUMEQ should be used during pregnancy only if the potential benefit justifies the potential risk. An Antiretroviral Pregnancy Registry has been established
- Nursing Mothers: Breastfeeding is not recommended due to the potential for HIV transmission and the potential for adverse reactions in nursing infants
- Patients with Impaired Renal Function: TRIUMEQ is not recommended in patients with creatinine clearance <50 mL/min
- Patients with Impaired Hepatic Function: If a dose reduction of abacavir, a component of TRIUMEQ, is required for patients with mild hepatic impairment, then the individual components should be used
Please see full Prescribing Information, including Boxed Warning and Medication Guide, for TRIUMEQ.
