WARNING: HYPERSENSITIVITY REACTIONS, AND EXACERBATIONS OF HEPATITIS B Hypersensitivity Reactions Serious and sometimes fatal hypersensitivity reactions, with multiple organ involvement, have occurred with abacavir, a component of TRIUMEQ (abacavir, dolutegravir, and lamivudine). Patients who carry the HLA ‑ B*5701 allele are at a higher risk of a hypersensitivity reaction to abacavir; although, hypersensitivity reactions have occurred in patients who do not carry the HLA ‑ B*5701 allele [see Warnings and Precautions ( 5.1 )] . TRIUMEQ is contraindicated in patients with a prior hypersensitivity reaction to abacavir and in HLA ‑ B*5701-positive patients [see Contraindications ( 4 ), Warnings and Precautions ( 5.1 )] . All patients should be screened for the HLA ‑ B*5701 allele prior to initiating therapy with TRIUMEQ or reinitiation of therapy with TRIUMEQ, unless patients have a previously documented HLA ‑ B*5701 allele assessment. Discontinue TRIUMEQ immediately if a hypersensitivity reaction is suspected, regardless of HLA-B*5701 status and even when other diagnoses are possible [see Contraindications ( 4 ), Warnings and Precautions ( 5.1 ) ]. Following a hypersensitivity reaction to TRIUMEQ, NEVER restart TRIUMEQ or any other abacavir ‑ containing product because more severe symptoms, including death can occur within hours. Similar severe reactions have also occurred rarely following the reintroduction of abacavir-containing products in patients who have no history of abacavir hypersensitivity [see Warnings and Precautions ( 5.1 )] . Exacerbations of Hepatitis B Severe acute exacerbations of hepatitis B have been reported in patients who are co ‑ infected with hepatitis B virus (HBV) and human immunodeficiency virus (HIV-1) and have discontinued lamivudine, a component of TRIUMEQ. Hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who discontinue TRIUMEQ and are co-infected with HIV-1 and HBV. If appropriate, initiation of anti ‑ hepatitis B therapy may be warranted [see Warnings and Precautions ( 5.2 )] . WARNING: HYPERSENSITIVITY REACTIONS, AND EXACERBATIONS OF HEPATITIS B See full prescribing information for complete boxed warning. Hypersensitivity Reactions • Serious and sometimes fatal hypersensitivity reactions have occurred with abacavir-containing products. ( 5.1 ) • Hypersensitivity to abacavir is a multi-organ clinical syndrome. ( 5.1 ) • Patients who carry the HLA-B*5701 allele are at a higher risk of experiencing a hypersensitivity reaction to abacavir. ( 5.1 ) • TRIUMEQ is contraindicated in patients with a prior hypersensitivity reaction to abacavir and in HLA-B*5701-positive patients. ( 4 ) • Discontinue TRIUMEQ as soon as a hypersensitivity reaction is suspected. Regardless of HLA-B*5701 status, permanently discontinue TRIUMEQ if hypersensitivity cannot be ruled out, even when other diagnoses are possible. ( 5.1 ) • Following a hypersensitivity reaction to TRIUMEQ, NEVER restart TRIUMEQ or any other abacavir-containing product. ( 5.1 ) Exacerbations of Hepatitis B • Severe acute exacerbations of hepatitis B have been reported in patients who are co-infected with hepatitis B virus (HBV) and human immunodeficiency virus (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. ( 5.2 )

5 WARNINGS AND PRECAUTIONS • Hepatotoxicity has been reported in patients receiving a dolutegravir-containing regimen. Monitoring for hepatotoxicity is recommended. ( 5.4 ) • Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogues. ( 5.5 ) • Embryo-fetal toxicity may occur when used at the time of conception and in early pregnancy. Avoid use of TRIUMEQ at the time of conception through the first trimester of pregnancy due to the risk of neural tube defects. Advise adolescents and adults of childbearing potential to use effective contraception. ( 2.2 , 5.6 , 8.1 , 8.3 ) • Hepatic decompensation, some fatal, has occurred in HIV-1/HCV co‑infected patients receiving combination antiretroviral therapy and interferon alfa with or without ribavirin. Discontinue TRIUMEQ as medically appropriate and consider dose reduction or discontinuation of interferon alfa, ribavirin, or both. ( 5.8 ) • Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy. ( 5.9 ) 5.1 Hypersensitivity Reactions Hypersensitivity reactions have been reported with the use of abacavir or dolutegravir, components of TRIUMEQ. Abacavir Serious and sometimes fatal hypersensitivity reactions have occurred with abacavir-containing regimens. See full prescribing information for ZIAGEN (abacavir). Abacavir hypersensitivity reactions have included multi-organ failure and anaphylaxis and typically occurred within the first 6 weeks of treatment with abacavir (median time to onset was 9 days); although abacavir hypersensitivity reactions have occurred any time during treatment [see Adverse Reactions ( 6.1 )] . Patients who carry the HLA‑B*5701 allele are at a higher risk of abacavir hypersensitivity reactions; although, patients who do not carry the HLA‑B*5701 allele have developed hypersensitivity reactions. Hypersensitivity to abacavir was reported in approximately 206 (8%) of 2,670 patients in 9 clinical trials with abacavir-containing products where HLA‑B*5701 screening was not performed. The incidence of suspected abacavir hypersensitivity reactions in clinical trials was 1% when subjects carrying the HLA-B*5701 allele were excluded. In any patient treated with abacavir, the clinical diagnosis of hypersensitivity reaction must remain the basis of clinical decision making. Due to the potential for severe, serious, and possibly fatal hypersensitivity reactions with abacavir: • All patients should be screened for the HLA‑B*5701 allele prior to initiating therapy with TRIUMEQ or reinitiation of therapy with TRIUMEQ, unless patients have a previously documented HLA‑B*5701 allele assessment. • TRIUMEQ is contraindicated in patients with a prior hypersensitivity reaction to abacavir and in HLA‑B*5701‑positive patients. • Before starting TRIUMEQ, review medical history for prior exposure to any abacavir-containing product. NEVER restart TRIUMEQ or any other abacavir-containing product following a hypersensitivity reaction to abacavir, regardless of HLA‑B*5701 status. • To reduce the risk of a life‑threatening hypersensitivity reaction, regardless of HLA‑B*5701 status, discontinue TRIUMEQ immediately if a hypersensitivity reaction is suspected, even when other diagnoses are possible (e.g., acute onset respiratory diseases such as pneumonia, bronchitis, pharyngitis, or influenza; gastroenteritis; or reactions to other medications). Clinical status, including liver chemistries, should be monitored and appropriate therapy initiated. • If a hypersensitivity reaction cannot be ruled out, do not restart TRIUMEQ or any other abacavir-containing products because more severe symptoms, which may include life-threatening hypotension and death, can occur within hours. • Clinically, it is not possible to determine whether a hypersensitivity reaction with TRIUMEQ would be caused by abacavir or dolutegravir. Therefore, never restart TRIUMEQ or any other abacavir- or dolutegravir-containing product in patients who have stopped therapy with TRIUMEQ due to a hypersensitivity reaction. • If a hypersensitivity reaction is ruled out, patients may restart TRIUMEQ. Rarely, patients who have stopped abacavir for reasons other than symptoms of hypersensitivity have also experienced life-threatening reactions within hours of reinitiating abacavir therapy. Therefore, reintroduction of TRIUMEQ, or any other abacavir-containing product, is recommended only if medical care can be readily accessed. • A Medication Guide and Warning Card that provide information about recognition of abacavir hypersensitivity reactions should be dispensed with each new prescription and refill. 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 less than 1% of subjects receiving TIVICAY in Phase 3 clinical trials. Discontinue TRIUMEQ and other suspect agents immediately if signs or symptoms of 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, oral blisters or lesions, conjunctivitis, facial edema, hepatitis, eosinophilia, angioedema, difficulty breathing). Clinical status, including liver aminotransferases, should be monitored and appropriate therapy initiated. Delay in stopping treatment with TRIUMEQ or other suspect agents after the onset of hypersensitivity may result in a life-threatening reaction. Clinically, it is not possible to determine whether a hypersensitivity reaction with TRIUMEQ would be caused by abacavir or dolutegravir. Therefore, never restart TRIUMEQ or any other abacavir- or dolutegravir-containing product in patients who have stopped therapy with TRIUMEQ due to a hypersensitivity reaction. 5.2 Posttreatment Exacerbations of Hepatitis in Patients with Hepatitis B Co-infection Clinical and laboratory evidence of exacerbations of hepatitis have occurred after discontinuation of lamivudine. See full prescribing information for EPIVIR (lamivudine). Patients should be closely monitored with both clinical and laboratory follow‑up for at least several months after stopping treatment. 5.3 Emergence of Lamivudine-Resistant HBV Safety and efficacy of lamivudine have not been established for treatment of chronic hepatitis B in subjects dually infected with HIV-1 and HBV. Emergence of hepatitis B virus variants associated with resistance to lamivudine has been reported in HIV‑1‑infected subjects who have received lamivudine‑containing antiretroviral regimens in the presence of concurrent infection with hepatitis B virus. See full prescribing information for EPIVIR-HBV (lamivudine). 5.4 Hepatotoxicity Hepatic adverse events have been reported in patients receiving a dolutegravir-containing regimen [see Adverse Reactions ( 6.1 )]. Patients with underlying hepatitis B or C may be at increased risk for worsening or development of transaminase elevations with use of TRIUMEQ [see Adverse Reactions ( 6.1 )]. 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. 5.5 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, including abacavir and lamivudine (components of TRIUMEQ). A majority of these cases have been in women. Female sex and obesity may be risk factors for the development of lactic acidosis and severe hepatomegaly with steatosis in patients treated with antiretroviral nucleoside analogues. See full prescribing information for ZIAGEN (abacavir) and EPIVIR (lamivudine). Treatment with TRIUMEQ 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. 5.6 Embryo-Fetal Toxicity Preliminary data from an observational study showed that dolutegravir, a component of TRIUMEQ, was associated with increased risk of neural tube defects when administered at the time of conception and in early pregnancy. As there is limited understanding of reported types of neural tube defects associated with dolutegravir use and because the date of conception may not be determined with precision, avoid use of TRIUMEQ at the time of conception through the first trimester of pregnancy [see Use in Specific Populations ( 8.1 )] . If there are plans to become pregnant or if pregnancy is confirmed within the first trimester while on TRIUMEQ, if possible, switch to an alternative regimen. Perform pregnancy testing before initiation of TRIUMEQ in adolescents and adults of childbearing potential to exclude use of TRIUMEQ during the first trimester of pregnancy [see Dosage and Administration ( 2.2 )] . Advise adolescents and adults of childbearing potential to consistently use effective contraception [see Use in Specific Populations ( 8.1 , 8.3 )] . 5.7 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, some of which may lead to [see Contraindications ( 4 ), Drug Interactions ( 7.3 )]: • Loss of therapeutic effect of TRIUMEQ and possible development of resistance. • Possible clinically significant adverse reactions from greater exposures of concomitant drugs. See Table 5 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 TRIUMEQ; review concomitant medications during therapy with TRIUMEQ; and monitor for the adverse reactions associated with the concomitant drugs. 5.8 Use with Interferon- and Ribavirin-Based Regimens Patients receiving interferon alfa with or without ribavirin and TRIUMEQ should be closely monitored for treatment‑associated toxicities, especially hepatic decompensation. See full prescribing information for EPIVIR (lamivudine). Discontinuation of TRIUMEQ should be considered as medically appropriate. Dose reduction or discontinuation of interferon alfa, ribavirin, or both should also be considered if worsening clinical toxicities are observed, including hepatic decompensation (e.g., Child‑Pugh greater than 6) (see full prescribing information for interferon and ribavirin). 5.9 Immune Reconstitution Syndrome Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy, including TRIUMEQ. During the initial phase of combination antiretroviral treatment, patients whose immune systems respond 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, and Guillain-Barré syndrome) 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. 5.10 Myocardial Infarction Several prospective, observational, epidemiological studies have reported an association with the use of abacavir and the risk of myocardial infarction (MI). Meta-analyses of randomized, controlled clinical trials have observed no excess risk of MI in abacavir-treated subjects as compared with control subjects. To date, there is no established biological mechanism to explain a potential increase in risk. In totality, the available data from the observational studies and from controlled clinical trials show inconsistency; therefore, evidence for a causal relationship between abacavir and the risk of MI is inconclusive. As a precaution, 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 (e.g., hypertension, hyperlipidemia, diabetes mellitus, smoking).

6 ADVERSE REACTIONS The following adverse reactions are discussed in other sections of the labeling: • Serious and sometimes fatal hypersensitivity reaction [see Boxed Warning , Warnings and Precautions ( 5.1 )] . • Exacerbations of hepatitis B [see Boxed Warning , Warnings and Precautions ( 5.3 )] . • Hepatotoxicity [see Warnings and Precautions ( 5.4 )] . • Lactic acidosis and severe hepatomegaly with steatosis [see Warnings and Precautions ( 5.5 )] . • Hepatic decompensation in patients co-infected with HIV-1 and Hepatitis C [see Warnings and Precautions ( 5.8 )] . • Immune reconstitution syndrome [see Warnings and Precautions ( 5.9 )] . • Myocardial infarction [see Warnings and Precautions ( 5.10 )] . The most commonly reported adverse reactions of at least moderate intensity and incidence at least 2% (in those receiving TRIUMEQ) were insomnia, headache, and fatigue. ( 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 clinical practice. Clinical Trials in Adults Serious and Fatal Abacavir-Associated Hypersensitivity Reactions: In clinical trials, serious and sometimes fatal hypersensitivity reactions have occurred with abacavir, a component of TRIUMEQ [see Boxed Warning , Warnings and Precautions ( 5.1 )]. These reactions have been characterized by 2 or more of the following signs or symptoms: (1) fever; (2) rash; (3) gastrointestinal symptoms (including nausea, vomiting, diarrhea, or abdominal pain); (4) constitutional symptoms (including generalized malaise, fatigue, or achiness); (5) respiratory symptoms (including dyspnea, cough, or pharyngitis). Almost all abacavir hypersensitivity reactions include fever and/or rash as part of the syndrome. Other signs and symptoms have included lethargy, headache, myalgia, edema, arthralgia, and paresthesia. Anaphylaxis, liver failure, renal failure, hypotension, adult respiratory distress syndrome, respiratory failure, myolysis, and death have occurred in association with these hypersensitivity reactions. Physical findings have included lymphadenopathy, mucous membrane lesions (conjunctivitis and mouth ulcerations), and maculopapular or urticarial rash (although some patients had other types of rashes and others did not have a rash). There were reports of erythema multiforme. Laboratory abnormalities included elevated liver chemistries, elevated creatine phosphokinase, elevated creatinine, and lymphopenia and abnormal chest x‑ray findings (predominantly infiltrates, which were localized). Serious Dolutegravir Hypersensitivity Reactions: In clinical trials, hypersensitivity reactions have occurred with dolutegravir, a component of TRIUMEQ [see Warnings and Precautions ( 5.1 )]. These hypersensitivity reactions have been characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury. Additional Treatment-Emergent Adverse Drug Reactions (ADRs) with Use of TRIUMEQ: The safety assessment of TRIUMEQ is primarily based on the analyses of data from a randomized, international, multicenter, double-blind, active-controlled trial, SINGLE (ING114467) and supported by data in treatment-experienced, INSTI-naïve subjects from SAILING (ING111762) and by data from other treatment-naïve trials. See full prescribing information for TIVICAY. Treatment-Naïve Subjects: In SINGLE, 833 adult subjects were randomized and received at least one dose of either dolutegravir (TIVICAY) 50 mg with fixed-dose abacavir and lamivudine (EPZICOM) once daily (n = 414) or fixed-dose efavirenz/emtricitabine/tenofovir (ATRIPLA) once daily (n = 419) (study treatment was blinded through Week 96 and open-label from Week 96 through Week 144). Through 144 weeks, the rate of adverse events leading to discontinuation was 4% in subjects receiving TIVICAY + EPZICOM and 14% in subjects receiving ATRIPLA once daily. Treatment-emergent ADRs of moderate to severe intensity observed in at least 2% of subjects in either treatment arm of SINGLE are provided in Table 2 . Table 2. Treatment-Emergent Adverse Drug Reactions of at Least Moderate Intensity (Grades 2 to 4) and at Least 2% Frequency in Treatment-Naïve Subjects in SINGLE (Week 144 Analysis) a Includes pooled terms: rash, rash generalized, rash macular, rash maculo-papular, rash pruritic, and drug eruption. Adverse Reaction TIVICAY + EPZICOM Once Daily (n = 414) ATRIPLA Once Daily (n = 419) Psychiatric Insomnia 3% 3% Depression 1% 2% Abnormal dreams <1% 2% Nervous System Dizziness <1% 5% Headache 2% 2% Gastrointestinal Nausea <1% 3% Diarrhea <1% 2% General Disorders Fatigue 2% 2% Skin and Subcutaneous Tissue Rash a <1% 6% Ear and Labyrinth Vertigo 0 2% Treatment-Experienced Subjects: SAILING is an international, double-blind trial in INSTI-naïve, antiretroviral treatment-experienced adult subjects. Subjects were randomized and received either TIVICAY 50 mg once daily or raltegravir 400 mg twice daily with investigator-selected background regimen consisting of up to 2 agents, including at least one fully active agent. At 48 weeks, the rate of adverse events leading to discontinuation was consistent with that seen in the overall treatment-naïve patient population. See full prescribing information for TIVICAY. The ADRs observed in the subset of subjects who received TIVICAY + EPZICOM were generally consistent with those seen in the overall treatment-naïve patient population. Less Common Adverse Reactions Observed in Clinical Trials: The following adverse reactions occurred in less than 2% of treatment-naïve or treatment-experienced subjects in any one trial. These events have been included because of their seriousness and/or assessment of potential causal relationship. Gastrointestinal Disorders: Abdominal pain, abdominal distention, abdominal discomfort, dyspepsia, flatulence, gastroesophageal reflux disease, upper abdominal pain, vomiting. General Disorders: Fever, lethargy. Hepatobiliary Disorders: Hepatitis. Metabolism and Nutrition Disorders: Anorexia, hypertriglyceridemia. Musculoskeletal Disorders: Arthralgia, myositis. Nervous System Disorders: Somnolence. Psychiatric Disorders: Suicidal ideation, attempt, behavior, or completion. These events were observed primarily in subjects with a pre-existing history of depression or other psychiatric illness. Nightmare and sleep disorder. Renal and Urinary Disorders: Renal impairment. Skin and Subcutaneous Tissue Disorders: Pruritus. Laboratory Abnormalities: Treatment-Naïve Subjects: Selected laboratory abnormalities (Grades 2 to 4) with a worsening grade from baseline and representing the worst-grade toxicity in at least 2% of subjects in SINGLE are presented in Table 3 . The mean change from baseline observed for selected lipid values is presented in Table 4 . Table 3. Selected Laboratory Abnormalities (Grades 2 to 4) in Treatment-Naïve Subjects in SINGLE (Week 144 Analysis) ULN = Upper limit of normal. Laboratory Abnormality TIVICAY + EPZICOM Once Daily (n = 414) ATRIPLA Once Daily (n = 419) ALT Grade 2 (>2.5-5.0 x ULN) 3% 5% Grade 3 to 4 (>5.0 x ULN) 1% <1% AST Grade 2 (>2.5-5.0 x ULN) 3% 4% Grade 3 to 4 (>5.0 x ULN) 1% 3% Creatine kinase Grade 2 (6.0-9.9 x ULN) 5% 3% Grade 3 to 4 (≥10.0 x ULN) 7% 8% Hyperglycemia Grade 2 (126-250 mg/dL) 9% 6% Grade 3 (>250 mg/dL) 2% <1% Lipase Grade 2 (>1.5-3.0 x ULN) 11% 11% Grade 3 to 4 (>3.0 ULN) 5% 4% Total neutrophils Grade 2 (0.75-0.99 x 10 9 ) 4% 5% Grade 3 to 4 (<0.75 x 10 9 ) 3% 3% Table 4. Mean Change from Baseline in Fasted Lipid Values in Treatment-Naïve Subjects in SINGLE (Week 144 Analysis a ) a Subjects on lipid-lowering agents at baseline were excluded from these analyses (TIVICAY + EPZICOM: n = 30 and ATRIPLA: n = 27). Seventy-two subjects initiated a lipid-lowering agent post-baseline; their last fasted on-treatment values (prior to starting the agent) were used regardless if they discontinued the agent (TIVICAY + EPZICOM: n = 36 and ATRIPLA: n = 36). Lipid TIVICAY + EPZICOM Once Daily (n = 414) ATRIPLA Once Daily (n = 419) Cholesterol (mg/dL) 24.0 26.7 HDL cholesterol (mg/dL) 5.4 7.2 LDL cholesterol (mg/dL) 16.0 14.6 Triglycerides (mg/dL) 13.6 31.9 Treatment-Experienced Subjects: Laboratory abnormalities observed in SAILING were generally similar compared with observations seen in the treatment-naïve trials. Hepatitis C Virus Co-infection: In SINGLE, the pivotal Phase 3 trial, subjects with hepatitis C virus co-infection were permitted to enroll provided that baseline liver chemistry tests did not exceed 5 times the upper limit of normal; subjects with hepatitis B co-infection were excluded. Overall, the safety profile in subjects with hepatitis C virus co-infection was similar to that observed in subjects without hepatitis C co-infection, although the rates of AST and ALT abnormalities were higher in the subgroup with hepatitis C virus co-infection for both treatment groups. Grades 2 to 4 ALT abnormalities in hepatitis C co-infected compared with HIV mono-infected subjects receiving TRIUMEQ were observed in 15% and 2% (vs. 24% and 4% of subjects treated with ATRIPLA) (Week 96 analysis), respectively [see Warnings and Precautions ( 5.2 )] . See also full prescribing information for TIVICAY. Changes in Serum Creatinine: Dolutegravir has been shown to increase serum creatinine due to inhibition of tubular secretion of creatinine without affecting renal glomerular function [see Clinical Pharmacology ( 12.2 )] . Increases in serum creatinine occurred within the first 4 weeks of treatment and remained stable through 144 weeks. In SINGLE, a mean change from baseline of 0.14 mg per dL (range: -0.25 mg per dL to 0.81 mg per dL) was observed after 144 weeks of treatment. Creatinine increases were similar in treatment-experienced subjects. Abacavir and Lamivudine: Laboratory abnormalities observed in clinical trials of ZIAGEN (in combination with other antiretroviral treatment) were anemia, neutropenia, liver function test abnormalities, and elevations of CPK, blood glucose, and triglycerides. Additional laboratory abnormalities observed in clinical trials of EPIVIR (in combination with other antiretroviral treatment) were thrombocytopenia and elevated levels of bilirubin, amylase, and lipase. Clinical Trials Experience in Pediatric Subjects Abacavir and Lamivudine: The safety of once-daily compared with twice-daily dosing of abacavir and lamivudine, administered as either single products or as EPZICOM, was assessed in the ARROW trial (n = 336). Primary safety assessment in the ARROW (COL105677) trial was based on Grade 3 and Grade 4 adverse events. One event of Grade 4 hepatitis in the once-daily cohort was considered as uncertain causality by the investigator and all other Grade 3 or 4 adverse events were considered not related by the investigator. No additional safety issues were identified in pediatric subjects compared with historical data in adults. Dolutegravir: IMPAACT P1093 is a 48-week multicenter, open-label, non-comparative trial of approximately 160 HIV‑1‑infected pediatric subjects aged 4 weeks to less than 18 years, of which, 23 treatment-experienced, INSTI-naïve subjects aged 12 to less than 18 years were enrolled [see Use in Specific Populations ( 8.4 ), Clinical Studies ( 14.2 )] . The ADR profile was similar to that for adults. Grade 2 ADRs reported by more than one subject were decreased neutrophil count (n = 2). No Grade 3 or 4 ADRs were reported. No ADRs led to discontinuation. The Grade 3 laboratory abnormalities reported in 1 subject each were elevated total bilirubin, elevated lipase, and decreased white blood cell count. There was one Grade 4 decreased neutrophil count. The changes in mean serum creatinine were similar to those observed in adults. 6.2 Postmarketing Experience In addition to adverse reactions reported from clinical trials, the following adverse reactions have been identified during postmarketing use with one or more of the components of TRIUMEQ. Because these reactions 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. Blood and Lymphatic Systems Aplastic anemia, anemia (including pure red cell aplasia and severe anemias progressing on therapy), lymphadenopathy, splenomegaly. Digestive Stomatitis. Gastrointestinal Pancreatitis. General Weakness. Hepatobiliary Disorders Acute liver failure, liver transplant. Hypersensitivity Sensitization reactions (including anaphylaxis), urticaria [see Warnings and Precautions ( 5.1 ), Adverse Reactions ( 6.1 )] . Investigations Weight increased. Metabolism and Nutrition Disorders Hyperlactemia. Musculoskeletal CPK elevation, muscle weakness, myalgia, rhabdomyolysis. Nervous Paresthesia, peripheral neuropathy, seizures. Psychiatric Anxiety. Respiratory Abnormal breath sounds/wheezing. Skin Alopecia, erythema multiforme. Suspected Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported in patients receiving abacavir primarily in combination with medications known to be associated with SJS and TEN, respectively. Because of the overlap of clinical signs and symptoms between hypersensitivity to abacavir and SJS and TEN, and the possibility of multiple drug sensitivities in some patients, abacavir should be discontinued and not restarted in such cases [see Adverse Reactions ( 6.1 )] .
