BIKTARVY is a three-drug fixed dose combination product containing bictegravir (BIC), emtricitabine (FTC), and tenofovir alafenamide (TAF). The recommended dosage of BIKTARVY is one tablet containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF taken orally once daily with or without food in [see Dosage and Administration (2.4)]:
The recommended dosage of BIKTARVY is one tablet containing 30 mg of BIC, 120 mg of FTC, and 15 mg of TAF taken orally once daily with or without food in:
For children unable to swallow a whole tablet, the tablet can be split and each part taken separately as long as all parts are ingested within approximately 10 minutes.
The recommended dosage of BIKTARVY in pregnant individuals is one tablet containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF taken orally once daily with or without food in pregnant individuals who are virologically-suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no known substitutions associated with resistance to any of the individual components of BIKTARVY. Lower exposures of BIKTARVY were observed during pregnancy; therefore, viral load should be monitored closely [see Drug Interactions (7.5), Use in Specific Populations (8.1), and Clinical Pharmacology (12.3)].
BIKTARVY is not recommended in patients with [see Dosage and Administration (2.2, 2.3), and Use in Specific Populations (8.6)]:
BIKTARVY 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)].
BIKTARVY tablets are available in two dose strengths:
BIKTARVY is contraindicated to be co-administered with:
Patients with HIV-1 should be tested for the presence of chronic 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 with HIV-1 and HBV who have discontinued products containing FTC and/or tenofovir disoproxil fumarate (TDF), and may occur with discontinuation of BIKTARVY. Patients with HIV-1 and HBV who discontinue BIKTARVY 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.
The concomitant use of BIKTARVY with certain 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)]:
See Table 3 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 BIKTARVY therapy; review concomitant medications during BIKTARVY therapy; and monitor for the adverse reactions associated with the concomitant drugs.
Immune reconstitution syndrome has been reported in patients treated with combination antiretroviral therapy. 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.
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)]. BIKTARVY is not recommended in patients with severe renal impairment (estimated creatinine clearance of 15 to below 30 mL/min), or patients with ESRD (estimated creatinine clearance below 15 mL/min) who are not receiving chronic hemodialysis, or patients with no antiretroviral treatment history and ESRD who are receiving chronic hemodialysis [see Dosage and Administration (2.4), and Use in Specific Populations (8.6)].
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 BIKTARVY, and during treatment with BIKTARVY, assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein in all patients as clinically appropriate. In patients with chronic kidney disease, also assess serum phosphorus. Discontinue BIKTARVY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome.
Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with the use of nucleoside analogs, including emtricitabine, a component of BIKTARVY, and tenofovir DF, another prodrug of tenofovir, alone or in combination with other antiretrovirals. Treatment with BIKTARVY 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).
The following adverse reactions are discussed in other sections of the labeling:
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 Adults with No Antiretroviral Treatment History
The primary safety assessment of BIKTARVY was based on data from two randomized, double-blind, active-controlled trials, Trial 1489 and Trial 1490, that enrolled 1274 adult participants with HIV-1 and no antiretroviral treatment history through Week 144. After Week 144, participants received open-label BIKTARVY in an optional extension phase for an additional 96 weeks (end of study). A total of 634 and 1025 participants received one tablet of BIKTARVY once daily during the double-blind (Week 144) and extension phases, respectively [see Clinical Studies (14.2)].
The most common adverse reactions (all Grades) reported in at least 5% of participants in the BIKTARVY group in either Trial 1489 or Trial 1490 were diarrhea, nausea, and headache. The proportion of participants who discontinued treatment through Week 144 with BIKTARVY, abacavir [ABC]/dolutegravir [DTG]/ lamivudine [3TC]), or DTG + FTC/TAF, due to adverse events, regardless of severity, was 1%, 2%, and 2%, respectively. Table 1 displays the frequency of adverse reactions (all Grades) greater than or equal to 2% in the BIKTARVY group.
| Trial 1489 | Trial 1490 | |||
|---|---|---|---|---|
| Adverse Reactions | BIKTARVY N=314 | ABC/DTG/3TC N=315 | BIKTARVY N=320 | DTG + FTC/TAF N=325 |
| Diarrhea | 6% | 4% | 3% | 3% |
| Nausea | 6% | 18% | 3% | 5% |
| Headache | 5% | 5% | 4% | 3% |
| Fatigue | 3% | 4% | 2% | 2% |
| Abnormal dreams | 3% | 3% | <1% | 1% |
| Dizziness | 2% | 3% | 2% | 1% |
| Insomnia | 2% | 3% | 2% | <1% |
| Abdominal distention | 2% | 2% | 1% | 2% |
* Frequencies of adverse reactions are based on all adverse events attributed to trial drugs by the investigator. No adverse reactions of Grade 2 or higher occurred in > 1% of participants treated with BIKTARVY.
Additional adverse reactions (all Grades) occurring in less than 2% of participants administered BIKTARVY in Trials 1489 and 1490 included vomiting, flatulence, dyspepsia, abdominal pain, rash, and depression.
Suicidal ideation, suicide attempt, and depression suicidal occurred in 2% of participants administered BIKTARVY; these events occurred primarily in participants with a preexisting history of depression, prior suicide attempt or psychiatric illness.
The majority (84%) of adverse events associated with BIKTARVY were Grade 1.
Adverse reactions in the open-label extension phases of Trials 1489 and 1490 were similar to those observed in participants administered BIKTARVY in the Week 144 analysis.
Clinical Trials in Adults with Virologically-Suppressed HIV-1
The safety of BIKTARVY in virologically-suppressed adults was based on Week 48 data from 282 participants in a randomized, double-blind, active-controlled trial (Trial 1844) in which virologically-suppressed participants were switched from either DTG + ABC/3TC or ABC/DTG/3TC to BIKTARVY; Week 48 data from 290 participants in an open-label, active-controlled trial in which virologically-suppressed participants were switched from a regimen containing atazanavir (ATV) (given with cobicistat or ritonavir) or darunavir (DRV) (given with cobicistat or ritonavir) plus either FTC/TDF or ABC/3TC, to BIKTARVY (Trial 1878); and Week 48 data from a randomized, double-blind active-controlled trial in which 284 virologically-suppressed participants were switched from DTG plus either FTC/TAF or FTC/TDF, to BIKTARVY (Trial 4030). Overall, the safety profile in virologically-suppressed adult participants in Trials 1844, 1878, and 4030 was similar to that in participants with no antiretroviral treatment history [see Clinical Studies (14.3)].
Clinical Trial in Adults with End Stage Renal Disease (ESRD) Receiving Chronic Hemodialysis
The safety of FTC and TAF (components of BIKTARVY) was evaluated in a single arm, open-label trial (Trial 1825) in virologically-suppressed adults with ESRD (estimated creatinine clearance of less than 15 mL/min) on chronic hemodialysis treated with FTC+TAF in combination with elvitegravir and cobicistat as a fixed-dose combination tablet for 96 weeks (N=55). 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 65% of participants and the most common serious adverse events were pneumonia (15%), fluid overload (7%), hyperkalemia (11%) and osteomyelitis (7%). Overall 7% of participants permanently discontinued treatment due to an adverse event. In an extension phase of Trial 1825 in which 10 participants switched to BIKTARVY for 48 weeks, the safety findings were similar to those in the initial phase of the open-label trial [see Use in Specific Populations (8.6), and Clinical Studies (14.3)].
Laboratory Abnormalities
The frequency of laboratory abnormalities (Grades 3–4) occurring in at least 2% of participants receiving BIKTARVY in Trials 1489 and 1490 are presented in Table 2.
| Trial 1489 | Trial 1490 | |||

| GGT (>5.0 × ULN) | 2% | 2% | 1% | 1% |
Changes in Serum Creatinine: BIC 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 by Week 4 of treatment and remained stable through Week 144. In Trials 1489 and 1490, median (Q1, Q3) serum creatinine increased by 0.11 (0.03, 0.19) mg per dL from baseline to Week 144 in the BIKTARVY group and was similar to the comparator groups who received ABC/DTG/3TC, or DTG + FTC/TAF. There were no discontinuations due to renal adverse events and renal serious adverse events were encountered in less than 1% of participants treated with BIKTARVY through Week 144 in clinical trials.
Changes in Bilirubin: In Trials 1489 and 1490, total bilirubin increases were observed in 17% of participants administered BIKTARVY through Week 144. Increases were primarily Grade 1 (1.0 to 1.5 × ULN) (12%) and Grade 2 (1.5 to 2.5 x ULN) (4%). Graded bilirubin increases in the ABC/DTG/3TC, and DTG + FTC/TAF groups, were 7% and 8%, respectively. Increases were primarily Grade 1 (5% ABC/DTG/3TC and 7% DTG + FTC/TAF) or Grade 2 (2% ABC/DTG/3TC and 2% DTG + FTC/TAF). There were no discontinuations due to hepatic adverse events through Week 144 in BIKTARVY clinical studies.
Clinical Trials in Pediatric Participants
The safety of BIKTARVY was evaluated in participants with virologically-suppressed HIV-1 between the ages of 12 to less than 18 years and weighing at least 35 kg (N=50) through Week 48 (cohort 1), in virologically-suppressed participants between the ages of 6 to less than 12 years and weighing at least 25 kg (N=50) through Week 24 (cohort 2), and in virologically suppressed participants at least 2 years of age and weighing at least 14 to less than 25 kg (N=22) through Week 24 (cohort 3) in an open label clinical trial (Trial 1474) [see Clinical Studies (14.4)]. No new adverse reactions or laboratory abnormalities were identified compared to those observed in adults. Adverse reactions were reported in 11% of pediatric participants. The majority (76%) of adverse reactions were Grade 1. No Grade 3 or 4 adverse reactions were reported. The adverse reaction reported by more than one subject (regardless of severity) was abdominal discomfort (n=2). One subject (1%) had Grade 2 adverse reactions of insomnia and anxiety that led to discontinuation of BIKTARVY. The other adverse reactions that occurred in single participants were similar to those seen in adults.
The following events have been identified during post approval use of BIKTARVY or products containing TAF. 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.
Renal and Urinary Disorders
Acute renal failure, acute tubular necrosis, proximal renal tubulopathy, and Fanconi syndrome
Skin and Subcutaneous Tissue Disorders
Angioedema, Stevens-Johnson syndrome/toxic epidermal necrolysis, and urticaria
Investigations

Because BIKTARVY is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended [see Indications and Usage (1)]. Comprehensive information regarding potential drug-drug interactions with other antiretroviral medications is not provided because the safety and efficacy of concomitant HIV-1 antiretroviral therapy is unknown.
BIC inhibits organic cation transporter 2 (OCT2) and multidrug and toxin extrusion transporter 1 (MATE1) in vitro. Coadministration of BIKTARVY with drugs that are substrates of OCT2 and MATE1 (e.g., dofetilide) may increase their plasma concentrations (see Table 3).
BIC is a substrate of CYP3A and UGT1A1. A drug that is a strong inducer of CYP3A and also an inducer of UGT1A1 can substantially decrease the plasma concentrations of BIC which may lead to loss of therapeutic effect of BIKTARVY and development of resistance [see Clinical Pharmacology (12.3)].
The use of BIKTARVY with a drug that is a strong inhibitor of CYP3A and also an inhibitor of UGT1A1 may significantly increase the plasma concentrations of BIC.
TAF is a substrate of P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP). Co-administration of drugs that inhibit P-gp and BCRP may increase the absorption and plasma concentrations of TAF [see Clinical Pharmacology (12.3)]. Co-administration of drugs that induce P-gp activity are expected to decrease the absorption of TAF, resulting in decreased plasma concentration of TAF, which may lead to loss of therapeutic effect of BIKTARVY and development of resistance (see Table 3).
Because FTC and tenofovir are primarily excreted by the kidneys by a combination of glomerular filtration and active tubular secretion, coadministration of BIKTARVY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of FTC, 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)].
Table 3 provides a listing of established or potentially clinically significant drug interactions with recommended prevention or management strategies. The drug interactions described are based on studies conducted with either BIKTARVY, the components of BIKTARVY (BIC, FTC, and TAF) as individual agents, or are drug interactions that may occur with BIKTARVY [see Contraindications (4), Warnings and Precautions (5.2), and Clinical Pharmacology (12.3)].
| Concomitant Drug Class: Drug Name | Effect on Concentration† | Clinical Comment |
|---|---|---|
| Antiarrhythmics: dofetilide | ↑ Dofetilide | Coadministration is contraindicated due to the potential for serious and/or life-threatening events associated with dofetilide therapy [see Contraindications (4)]. |
| Anticonvulsants: carbamazepine‡ oxcarbazepine phenobarbital phenytoin | ↓ BIC ↓ TAF | Coadministration with alternative anticonvulsants should be considered. |
| Antimycobacterials: rifabutin‡ rifampin‡,§ rifapentine | ↓ BIC ↓ TAF | Coadministration with rifampin is contraindicated due to the effect of rifampin on the BIC component of BIKTARVY [see Contraindications (4)]. Coadministration with rifabutin or rifapentine is not recommended. |

| Oral medications or supplements containing polyvalent cations (e.g., Mg, Al, Ca, Fe): Calcium or iron supplements‡ Cation-containing antacids or laxatives‡ Sucralfate Buffered medications | ↓ BIC | Antacids containing Al/Mg: BIKTARVY can be taken at least 2 hours before or 6 hours after taking antacids containing Al/Mg. Routine administration of BIKTARVY together with, or 2 hours after, antacids containing Al/Mg is not recommended. Supplements or Antacids containing Calcium or Iron: BIKTARVY and supplements or antacids containing calcium or iron can be taken together with food. Routine administration of BIKTARVY under fasting conditions together with, or 2 hours after, supplements or antacids containing calcium or iron is not recommended. In pregnant individuals: Antacids containing Al/Mg: BIKTARVY can be taken at least 2 hours before or 6 hours after antacids containing Al/Mg regardless of food intake. Supplements or Antacids containing Calcium or Iron: BIKTARVY and supplements or antacids containing calcium or iron can be taken together with food; but when taken on an empty stomach, BIKTARVY should be taken at least 2 hours before or 6 hours after supplements or antacids containing calcium or iron. |
| Metformin | ↑ Metformin | Refer to the prescribing information of metformin for assessing the benefit and risk of concomitant use of BIKTARVY and metformin. |
Based on drug interaction studies conducted with BIKTARVY or the components of BIKTARVY, no clinically significant drug interactions have been observed when BIKTARVY is combined with the following drugs: ethinyl estradiol, ledipasvir/sofosbuvir, midazolam, norgestimate, sertraline, sofosbuvir, sofosbuvir/velpatasvir, and sofosbuvir/velpatasvir/voxilaprevir.
Pregnancy Exposure Registry
There is a pregnancy exposure registry that monitors pregnancy outcomes in individuals exposed to BIKTARVY during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258-4263.
Risk Summary
Available data from observational studies and the APR with BIC, FTC and TAF use during pregnancy have not established a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. Reports of pregnant individuals treated with products containing BIC, FTC, or TAF contribute to APR’s overall risk assessment for these components. Available data from the APR show no statistically significant difference in the overall risk of major birth defects for BIC, 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. The estimated background rate of miscarriage in the clinically recognized pregnancies in the U.S. general population is 15-20%.
BIKTARVY safety has also been evaluated in an open-label trial that demonstrated safety findings that were consistent with other trials in adults (see Data).
In animal reproduction studies, no evidence of adverse developmental outcomes was observed with the components of BIKTARVY at exposures that were either not maternally toxic (rabbits) or greater than (rats and mice) those in humans at the recommended human dose (RHD) (see Data ). During organogenesis, systemic exposures (AUC) to BIC were approximately 36 (rats) and 0.6 times (rabbits), to FTC were approximately 60 (mice) and 108 times (rabbits), and to TAF were approximately 2 (rats) and 78 times (rabbits) the exposure at the RHD of BIKTARVY. In rat pre/postnatal development studies, maternal systemic exposures (AUC) were 30 times (BIC), 60 times (FTC), and 19 times (TDF) the exposures of each component in humans at the RHD.
Data
Human Data
BIKTARVY was evaluated in an open-label clinical trial of 33 virologically-suppressed (HIV-1 RNA < 50 copies/mL) pregnant adults with HIV-1 and no known substitutions associated with resistance to BIC, FTC, or TAF. Pregnant adults were administered BIKTARVY (containing 50 mg of BIC, 200 mg of FTC and 25 mg of TAF) once daily from the second or third trimester through postpartum. Exposures of BIC, FTC, and TAF were lower during pregnancy as compared to postpartum [see Clinical Pharmacology (12.3)]. All 32 adult participants who completed the study maintained viral suppression during pregnancy, at delivery, and through Week 18 postpartum. The median CD4+ cell count at baseline was 558 cells/µL, and the median change in CD4+ cell count from baseline to Week 12 postpartum was 159 cells/μL. All 29 neonate participants had negative/nondetectable HIV-1 PCR results at birth and/or at 4 to 8 weeks post-birth. The safety findings in this trial were consistent with other trials in adults.
BIKTARVY was only studied in pregnant individuals who were virologically-suppressed, and lower plasma exposures of BIKTARVY were observed during pregnancy compared to post-partum. Therefore, BIKTARVY is recommended in pregnant individuals who are virologically-suppressed on a stable antiretroviral regimen with no known substitutions associated with resistance to any of the individual components of BIKTARVY.
Bictegravir (BIC):
Based on prospective reports to the APR of over 500 exposures to a BIC-containing regimen during pregnancy resulting in live births (including 423 exposed in the first trimester and 113 exposed in the second/third trimester), the prevalence of birth defects in live births was 4.3% (95% CI: 2.5% to 6.6%) and 1.8% (0.2%, 6.2%) following first and second/third trimester exposure, respectively, to a BIC-containing regimen.
Emtricitabine (FTC):
Based on prospective reports to the APR of over 6,500 exposures to FTC-containing regimens during pregnancy resulting in live births (including over 4,800 exposed in the first trimester and over 1,700 exposed in the second/third trimester), the prevalence of birth defects in live births was 2.9% (95% CI: 2.5% to 3.4%) and 2.8% (95% CI: 2.1% 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 1,200 exposures to TAF-containing regimens during pregnancy resulting in live births (including over 1000 exposed in the first trimester and over 200 exposed in the second/third trimester), the prevalence of birth defects in live births was 3.9% (95% CI: 2.8% to 5.2%) and 4.8% (95% CI: 2.5% to 8.3%) following first and second/third trimester exposure, respectively, to TAF-containing regimens.
Methodological limitations of the APR include the use of MACDP as the external comparator group. The MACDP population is not disease-specific, evaluates individuals and infants from a limited geographic area, and does not include outcomes for births that occurred at less than 20 weeks gestation.
Animal Data
Bictegravir: BIC was administered orally to pregnant rats (5, 30, or 300 mg/kg/day) and rabbits (100, 300, or 1000 mg/kg/day) on gestation days 7 through 17, and 7 through 19, respectively. No adverse embryo-fetal effects were observed in rats and rabbits at BIC exposures (AUC) of up to approximately 36 (rats) and 0.6 (rabbits) times the exposure in humans at the RHD of BIKTARVY. Spontaneous abortion, increased clinical signs [fecal changes, thin body, and cold-to-touch], and decreased body weight were observed at a maternally toxic dose in rabbits (1000 mg/kg/day; approximately 1.4 times higher than human exposure at the RHD).
In a pre/postnatal development study, BIC was administered orally to pregnant rats (up to 300 mg/kg/day) from gestation days 6 to lactation/post-partum day 24. No significant adverse effects were observed in the offspring exposed daily from before birth (in utero) through lactation at maternal and pup exposures (AUC) of approximately 30 and 11 times higher, respectively, than human exposures at the RHD.
Emtricitabine: FTC 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 approximately 60 times higher and in rabbits at approximately 108 times higher than human exposures at the RHD.
In a pre/postnatal development study with FTC, 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 RHD.
Tenofovir alafenamide: 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 of approximately 2 (rats) and 78 (rabbits) times higher than the exposure in humans at the recommended daily dose of BIKTARVY. TAF is rapidly converted to tenofovir; the observed tenofovir exposure in rats and rabbits were 55 (rats) and 86 (rabbits) times higher than human tenofovir exposures at the RHD. 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 12 [19] times higher than the exposures in humans at the RHD of BIKTARVY.
Risk Summary
Data from the published literature report the presence of BIC, FTC, TAF, and tenofovir in human milk. There are no data on the effects of BIC on the breastfed child. Data from the published literature have not reported adverse effects of FTC or TAF on a breastfed child. There are no data on the effects of BIC, FTC or TAF on milk production.
Potential risks of breastfeeding include: (1) HIV-1 transmission to HIV-1–negative infants; (2) developing viral resistance in HIV-1–positive infants; and (3) adverse reactions in a breastfed infant similar to those seen in adults.
The safety and effectiveness of BIKTARVY have been established as a complete regimen for the treatment of human immunodeficiency virus type 1 (HIV-1) infection in pediatric patients weighing at least 14 kg:
Use of BIKTARVY in pediatric patients weighing at least 14 kg is supported by the following:
The safety and efficacy of BIKTARVY in these pediatric participants were similar to that in adults, and there was no clinically significant change in exposure for the components of BIKTARVY [see Adverse Reactions (6.1), Clinical Pharmacology (12.3), and Clinical Studies (14.4)].
Safety and effectiveness of BIKTARVY in pediatric patients weighing less than 14 kg have not been established.
Clinical trials in virologically-suppressed participants (Trials 4449, 1844, and 1878) included 111 participants aged 65 years and over who received BIKTARVY, including 86 patients from an open-label, single-arm trial of participants aged 65 years and over who were switched from their previous antiretroviral regimen to BIKTARVY [see Clinical Studies (14.3) ]. Of the total number of BIKTARVY-treated patients in these trials, 100 (90%) were 65 to 74 years of age, and 11 (10%) were 75 to 84 years of age. No overall differences in safety or effectiveness were observed between elderly participants and adults between 18 and less than 65 years of age, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
The pharmacokinetics, safety, virologic and immunologic responses of FTC and TAF (components of BIKTARVY) were evaluated in a single arm, open-label trial (Trial 1825) in virologically-suppressed adults with ESRD (estimated creatinine clearance of less than 15 mL/min) on chronic hemodialysis treated with FTC+TAF in combination with elvitegravir and cobicistat as a fixed-dose combination tablet for 96 weeks (N=55). In an extension phase of Trial 1825, 10 virologically-suppressed participants switched to BIKTARVY and all remained virologically suppressed for 48 weeks [see Adverse Reactions (6.1), Clinical Pharmacology (12.3), and Clinical Studies (14.3)].
No dosage adjustment of BIKTARVY is recommended in patients with estimated creatinine clearance greater than or equal to 30 mL/min, or in virologically-suppressed adults (estimated creatinine clearance below 15 mL/min) who are receiving chronic hemodialysis. On days of hemodialysis, administer the daily dose of BIKTARVY after completion of hemodialysis treatment [see Dosage and Administration (2.2)]
BIKTARVY is not recommended in patients with estimated creatinine clearance of below 30 mL/min, by Cockcroft-Gault, or patients with ESRD (estimated creatinine clearance below 15 mL/min) who are not receiving chronic dialysis, or patients with no antiretroviral treatment history and ESRD who are receiving chronic dialysis, as the safety and/or efficacy of BIKTARVY has not been established in these populations [see Dosage and Administration (2.4), Warnings and Precautions (5.4), and Clinical Pharmacology (12.3)].
No dosage adjustment of BIKTARVY is recommended in patients with mild (Child-Pugh Class A) or moderate (Child-Pugh Class B) hepatic impairment. BIKTARVY has not been studied in patients with severe hepatic impairment (Child-Pugh Class C). Therefore, BIKTARVY is not recommended for use in patients with severe hepatic impairment [see Dosage and Administration (2.4), and Clinical Pharmacology (12.3)].
No data are available on overdose of BIKTARVY in patients. If overdose occurs, monitor the patient for evidence of toxicity. Treatment of overdose with BIKTARVY consists of general supportive measures including monitoring of vital signs as well as observation of the clinical status of the patient.
Hemodialysis treatment removes approximately 30% of the FTC dose over a 3-hour dialysis period starting within 1.5 hours of FTC dosing (blood flow rate of 400 mL/min and a dialysate flow rate of 600 mL/min). It is not known whether FTC can be removed by peritoneal dialysis.
Tenofovir is efficiently removed by hemodialysis with an extraction coefficient of approximately 54%.
BIKTARVY (bictegravir, emtricitabine, and tenofovir alafenamide) is a fixed dose combination tablet containing bictegravir (BIC), emtricitabine (FTC), and tenofovir alafenamide (TAF) for oral administration.
BIKTARVY tablets are available in two dose strengths:
Both dose strengths of BIKTARVY tablets include the following inactive ingredients: croscarmellose sodium, magnesium stearate, and microcrystalline cellulose. The tablets for both dose strengths are film-coated with a coating material containing iron oxide black, iron oxide red, polyethylene glycol, polyvinyl alcohol, talc, and titanium dioxide.

Tenofovir alafenamide fumarate is a white to off-white or tan powder with a solubility of 4.7 mg per mL in water at 20 °C.
BIKTARVY is a fixed dose combination of antiretroviral drugs bictegravir (BIC), emtricitabine (FTC), and tenofovir alafenamide (TAF) [see Microbiology (12.4)].
Cardiac Electrophysiology
In a thorough QT/QTc trial in 48 healthy participants, BIC at doses 1.5 and 6 times the recommended dose did not affect the QT/QTc interval and did not prolong the PR interval. In a thorough QT/QTc trial in 48 healthy participants, TAF at the recommended dose or at a dose 5 times the recommended dose, did not affect the QT/QTc interval and did not prolong the PR interval. The effect of FTC on the QT interval is not known.
Effects on Serum Creatinine
Mean change from baseline in serum creatinine in healthy participants who received BIC 75 mg (1.5 times the approved recommended dosage) once daily with food for 14 days was 0.1 mg per dL on Days 7 and 14 compared to placebo. BIC did not have a significant effect on the estimated creatinine clearance or on the actual glomerular filtration rate (determined by the clearance of probe drug, iohexol).
The pharmacokinetic (PK) properties of BIKTARVY components are provided in Table 4. The multiple dose PK parameters of BIKTARVY components (based on population pharmacokinetic analysis) are provided in Table 5.

Specific Populations
Patients with Renal Impairment
No clinically relevant differences in the pharmacokinetics of BIC, TAF, or its metabolite tenofovir were observed between participants with severe renal impairment (estimated creatinine clearance of 15 to less than 30 mL/min, by Cockcroft-Gault method) and healthy participants in Phase 1 studies. In a separate Phase 1 study of FTC alone, FTC exposures were increased in participants with severe renal impairment.
The pharmacokinetics of BIC, FTC and TAF were evaluated in a subset of HIV-1 infected virologically-suppressed participants with ESRD (estimated creatinine clearance less than 15 mL/min, by Cockcroft-Gault method) receiving chronic hemodialysis in Trial 1825. The pharmacokinetics of TAF were similar between healthy participants and participants with ESRD receiving chronic hemodialysis; increases in FTC and tenofovir exposures in participants with ESRD were not considered clinically relevant. Median (minimum, maximum) BIC Ctrough values in participants (n=7) with ESRD who received BIKTARVY were 846 ng/mL (288, 1810) compared to 2540 ng/mL (757, 6499) in participants (N=584) with normal renal function. Despite significantly lower BIC Ctrough values in the virologically-suppressed ESRD population, virologic suppression was maintained [see Use in Specific Populations (8.6), and Clinical Studies (14.3)].
Patients with Hepatic Impairment
Bictegravir: Clinically relevant changes in the pharmacokinetics of BIC were not observed in participants with moderate (Child-Pugh Class B) hepatic impairment.
Emtricitabine: The pharmacokinetics of FTC has not been studied in participants with hepatic impairment; however, FTC is not significantly metabolized by liver enzymes, so the impact of hepatic impairment should be limited.
Tenofovir Alafenamide: Clinically relevant changes in the pharmacokinetics of TAF or its metabolite tenofovir were not observed in participants with mild or moderate (Child-Pugh Class A and B) hepatic impairment [see Use in Specific Populations (8.7)].
Hepatitis B and/or Hepatitis C Virus Coinfection
The pharmacokinetics of BIC, FTC, and TAF have not been evaluated in participants with hepatitis B and/or C virus.
Geriatric Patients
The pharmacokinetics of BIC, FTC, and TAF have not been fully evaluated in the elderly (65 years of age and older). Population pharmacokinetics analysis of HIV-infected participants in Phase 3 trials of BIKTARVY showed that age did not have a clinically relevant effect on exposures of BIC and TAF up to 74 years of age [see Use in Specific Populations (8.5)].
Pediatric Patients
Mean BIC Ctrough was lower in 50 pediatric patients aged 12 to less than 18 years and weighing at least 35 kg who received BIKTARVY in Trial 1474 relative to adults following administration of BIKTARVY, but was not considered clinically significant based on exposure-response relationships; exposures of FTC and TAF in these pediatric patients were similar to those in adults (Table 6).

Drug Interaction Studies
As BIKTARVY is a complete regimen for the treatment of HIV-1 infection, comprehensive information regarding potential drug-drug interactions with other antiretroviral agents is not provided.
BIC is a substrate of CYP3A and UGT1A1.
BIC is an inhibitor of OCT2 and MATE1. At clinically relevant concentrations, BIC is not an inhibitor of hepatic transporters OATP1B1, OATP1B3, OCT1, BSEP, renal transporters OAT1 and OAT3, or CYP (including CYP3A) or UGT1A1 enzymes.
TAF is a substrate of P-gp and BCRP.
At clinically relevant concentrations, TAF is not an inhibitor of drug transporters P-gp, BCRP, hepatic transporters OATP1B1, OATP1B3, OCT1, BSEP, renal transporters OAT1, OAT3, OCT2, MATE1, or CYP (including CYP3A) or UGT1A1 enzymes.
Drug interaction studies were conducted with BIKTARVY or its components. Tables 10 and 11 summarize the pharmacokinetic effects of other drugs on BIC and TAF, respectively. Table 12 summarizes the pharmacokinetic effects of BIKTARVY or its components on other drugs.

Mechanism of Action
Bictegravir: BIC inhibits the strand transfer activity of HIV-1 integrase (integrase strand transfer inhibitor; INSTI), an HIV-1 encoded enzyme that is required for viral replication. Inhibition of integrase prevents the integration of linear HIV-1 DNA into host genomic DNA, blocking the formation of the HIV-1 provirus and propagation of the virus.
Emtricitabine: FTC, a synthetic nucleoside analog of cytidine, is phosphorylated by cellular enzymes to form emtricitabine 5'-triphosphate. Emtricitabine 5'-triphosphate inhibits the activity of the HIV-1 RT by competing with the natural substrate deoxycytidine 5'-triphosphate and by being incorporated into nascent viral DNA which results in chain termination. Emtricitabine 5′-triphosphate is a weak inhibitor of mammalian DNA polymerases α, β, Ɛ, and mitochondrial DNA polymerase γ.
Tenofovir Alafenamide: TAF is a phosphonamidate prodrug of tenofovir (2′-deoxyadenosine monophosphate analog). Plasma exposure to TAF allows for permeation into cells and then TAF is intracellularly converted to tenofovir through hydrolysis by cathepsin A. Tenofovir is subsequently phosphorylated by cellular kinases to the active metabolite tenofovir diphosphate. Tenofovir diphosphate inhibits HIV-1 replication through incorporation into viral DNA by the HIV RT, which results in DNA chain-termination. Tenofovir diphosphate is a weak inhibitor of mammalian DNA polymerases that include mitochondrial DNA polymerase γ and there is no evidence of toxicity to mitochondria in cell culture.
Antiviral Activity in Cell Culture
The triple combination of BIC, FTC, and TAF was not antagonistic with respect to antiviral activity in cell culture.
Bictegravir: The antiviral activity of BIC against laboratory and clinical isolates of HIV-1 was assessed in lymphoblastoid cell lines, PBMCs, primary monocyte/macrophage cells, and CD4+ T-lymphocytes. In MT-4 cells (human lymphoblastoid T-cell line) acutely infected with HIV-1 IIIB, the mean 50% effective concentration (EC50) was 2.4±0.4 nM, and the protein-adjusted EC95 value was 361 nM (0.162 micrograms per mL). BIC displayed antiviral activity in activated PBMCs against clinical isolates of HIV-1 representing groups M, N, and O, including subtypes A, B, C, D, E, F, and G, with a median EC50 value of 0.55 nM (range <0.05 to 1.71 nM). The EC50 value against a single HIV-2 isolate was 1.1 nM.
Emtricitabine: The antiviral activity of FTC against laboratory and clinical isolates of HIV-1 was assessed in T lymphoblastoid cell lines, the MAGI-CCR5 cell line, and PBMCs. In PBMCs acutely infected with HIV-1 subtypes A, B, C, D, E, F, and G, the median EC50 value for FTC was 9.5 nM (range 1 to 30 nM) and against HIV-2 was 7 nM.
Tenofovir Alafenamide: The antiviral activity of TAF against laboratory and clinical isolates of HIV-1 subtype B was assessed in lymphoblastoid cell lines, PBMCs, primary monocyte/macrophage cells and CD4-T lymphocytes. The EC50 values for TAF ranged from 2.0 to 14.7 nM. TAF displayed antiviral activity in cell culture against all HIV-1 groups (M, N, O), including subtypes A, B, C, D, E, F, and G (EC50 values ranged from 0.1 to 12 nM) and strain specific activity against HIV-2 (EC50 values ranged from 0.9 to 2.6 nM).
Resistance
In Cell Culture
Bictegravir: HIV-1 isolates with reduced susceptibility to BIC have been selected in cell culture. In one selection with BIC, a virus pool emerged expressing amino acid substitutions M50I and R263K in the HIV-1 integrase. M50I, R263K, and M50I+R263K substitutions, when introduced into a wild-type virus by site-directed mutagenesis, conferred 1.3-, 2.2-, and 2.9-fold reduced susceptibility to BIC, respectively. In a second selection, emergence of amino acid substitutions T66I and S153F was detected, and 0.4-, 1.9-, and 0.5-fold reductions in BIC susceptibility were observed with T66I, S153F, and T66I+S153F, respectively. In addition, S24G and E157K substitutions emerged during the selection process.
Emtricitabine: HIV-1 isolates with reduced susceptibility to FTC were selected in cell culture and in participants treated with FTC. Reduced susceptibility to FTC was associated with M184V or I substitutions in HIV-1 RT.
Tenofovir Alafenamide: HIV-1 isolates with reduced susceptibility to TAF were selected in cell culture. HIV-1 isolates selected by TAF expressed a K65R substitution in HIV-1 RT, sometimes in the presence of S68N or L429I substitutions; in addition, a K70E substitution in HIV-1 RT was observed.
In Clinical Trials
In Participants with No Antiretroviral Treatment History: Pooled results of genotypic resistance analyses were performed on paired baseline and on-treatment HIV-1 isolates from participants receiving BIKTARVY in Trials 1489 and 1490 through Week 144 of the double-blind phase (N=634) or Week 96 of the extension phase (n=1025) [see Clinical Studies (14.2)] who had HIV-1 RNA greater than or equal to 200 copies/mL at the time of confirmed virologic failure or early study drug discontinuation. In the final resistance analysis population, no specific amino acid substitutions emerged consistently in the 11 participants with treatment failure and with evaluable genotypic resistance data and failed to establish an association with genotypic BIC resistance. There were no treatment-emergent NRTI resistance-associated substitutions detected in the 11 evaluated treatment failure isolates. Phenotypic resistance analyses of failure isolates found fold-changes in drug susceptibility below the biological or clinical cutoffs for BIC, FTC, and TFV, compared to wild-type reference HIV-1.
In Virologically-Suppressed Adult participants: In 2 of the switch trials, Trials 1844 and 1878, of virologically suppressed HIV-1 infected participants (n=572), only one participants with virologic rebound in the resistance analysis population had IN genotypic and phenotypic data, and 2 rebounders had RT genotypic and phenotypic data. No participants had HIV-1 with treatment-emergent genotypic or phenotypic resistance to BIC, FTC, or TAF. In Trial 4030, no participants receiving BIKTARVY had treatment-emergent phenotypic resistance to BIC, FTC, or TAF.
In Virologically-Suppressed Pediatric Participants: In Trial 1474 [see Clinical Studies (14.4)], two of 50 participants in cohort 1 were evaluated for the development of resistance through Week 48; no amino acid substitutions known to be associated with resistance to BIC, FTC, or TFV were detected. No participants in cohort 2 or 3 met the criteria for resistance analyses through Week 24.
Cross-Resistance
Bictegravir: Cross-resistance has been observed among INSTIs. The susceptibility of BIC was tested against 64 clinical isolates expressing known INSTI resistance-associated substitutions listed by IAS-USA (20 with single substitutions and 44 with 2 or more substitutions). Isolates with a single INSTI-resistance substitution including E92Q, T97A, Y143C/R, Q148R, and N155H showed less than 2-fold reduced susceptibility to BIC. All isolates (n=14) with more than 2.5-fold reduced susceptibility to BIC (above the biological cutoff for BIC) contained G140A/C/S and Q148H/R/K substitutions; the majority (64.3%, 9/14) had a complex INSTI resistance pattern with an additional INSTI-resistance substitution L74M, T97A, or E138A/K. Of those evaluated isolates containing G140A/C/S and Q148H/R/K substitutions in the absence of additional INSTI-resistance substitutions, 38.5% (5/13) showed more than 2.5-fold reduction. In addition, site-directed mutant viruses with G118R (dolutegravir and raltegravir treatment-emergent substitution) and G118R+T97A had 3.4- and 2.8-fold reduced susceptibility to BIC, respectively.
BIC demonstrated equivalent antiviral activity with less than 2-fold reductions in susceptibility against HIV-1 variants expressing substitutions associated with resistance to NNRTIs, NRTIs, and PIs, compared with the wild-type virus.
Emtricitabine: Cross-resistance has been observed among NRTIs. FTC-resistant viruses with an M184V/I substitution in HIV-1 RT were cross-resistant to lamivudine. HIV-1 isolates containing the K65R RT substitution, selected in vivo by abacavir, didanosine, and tenofovir, demonstrated reduced susceptibility to inhibition by FTC.
Tenofovir Alafenamide: Cross-resistance has been observed among NRTIs. Tenofovir resistance substitutions K65R and K70E result in reduced susceptibility to abacavir, didanosine, emtricitabine, lamivudine, and tenofovir. HIV-1 with multiple thymidine analog substitutions (M41L, D67N, K70R, L210W, T215F/Y, K219Q/E/N/R), or multinucleoside resistant HIV-1 with a T69S double insertion mutation or with a Q151M substitution complex including K65R, showed reduced susceptibility to TAF in cell culture.
Bictegravir
BIC was not carcinogenic in a 6-month rasH2 transgenic mouse study at doses of up to 100 mg/kg/day in males and 300 mg/kg/day in females. BIC was not carcinogenic in a 2-year rat study at doses up to 300 mg/kg/day, which resulted in exposures of approximately 31 times the exposure in humans at the recommended dose of BIKTARVY.
BIC was not genotoxic in the reverse mutation bacterial test (Ames test), mouse lymphoma or rat micronucleus assays.
BIC did not affect fertility, reproductive performance or embryonic viability in male and female rats at 29 times higher exposures (AUC) than in humans at the recommended dose of BIKTARVY.
Emtricitabine
In long-term carcinogenicity studies of FTC, no drug-related increases in tumor incidence were found in mice at doses up to 750 mg per kg per day (25 times the human systemic exposure at the recommended dose of BIKTARVY) or in rats at doses up to 600 mg per kg per day (30 times the human systemic exposure at the recommended dose of BIKTARVY).
FTC was not genotoxic in the reverse mutation bacterial test (Ames test), mouse lymphoma or mouse micronucleus assays.
FTC did not affect fertility in male rats at approximately 140 times or in male and female mice at approximately 60 times higher exposures (AUC) than in humans given the recommended dose of BIKTARVY. Fertility was normal in the offspring of mice 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 dose of BIKTARVY.
Tenofovir Alafenamide
Since TAF is rapidly converted to tenofovir and a lower tenofovir exposure in rats and mice was observed after TAF administration compared to TDF administration, carcinogenicity studies were conducted only with TDF. Long-term oral carcinogenicity studies of TDF in mice and rats were carried out at exposures up to approximately 10 times (mice) and 4 times (rats) those observed in humans following a 300 mg dose of TDF. The tenofovir exposure in these studies was approximately 151 times (mice) and 51 times (rat) those observed in humans after administration of the daily recommended dose of BIKTARVY. At the high dose in female mice, liver adenomas were increased at tenofovir exposures approximately 151 times the exposure observed in humans at the recommended dose of BIKTARVY. In rats, the study was negative for carcinogenic findings.
TAF was not genotoxic in the reverse mutation bacterial test (Ames test), mouse lymphoma or rat micronucleus assays.
There were no effects on fertility, mating performance or early embryonic development when TAF was administered to male rats at a dose equivalent to 155 times the human dose of BIKTARVY based on body surface area comparisons for 28 days prior to mating and to female rats for 14 days prior to mating through Day 7 of gestation.
Minimal to slight infiltration of mononuclear cells in the posterior uvea was observed in dogs with similar severity after three and nine month administration of TAF; reversibility was seen after a three month recovery period. No eye toxicity was observed in the dog at systemic exposures of 7 (TAF) and 14 (tenofovir) times the exposure seen in humans with the recommended daily dose of BIKTARVY.
The efficacy and safety of BIKTARVY were evaluated in the trials summarized in Table 13.

♠ Participants received FTC+TAF in combination with elvitegravir and cobicistat for 96 weeks, followed by an extension phase in which 10 participants received BIKTARVY for 48 weeks.
In Trial 1489, adults were randomized in a 1:1 ratio to receive either BIKTARVY (containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF) (N=314) or ABC/DTG/3TC (600 mg/50 mg/300 mg) (N=315) once daily. In Trial 1490, participants were randomized in a 1:1 ratio to receive either BIKTARVY (N=320) or DTG + FTC/TAF (50 mg + 200 mg/25 mg) (N=325) once daily.
In Trial 1489, the mean age was 34 years (range 18–71), 90% were male, 57% were White, 36% were Black, and 3% were Asian. 22% of patients identified as Hispanic/Latino. The mean baseline plasma HIV-1 RNA was 4.4 log10 copies/mL (range 1.3–6.5). The mean baseline CD4+ cell count was 464 cells per mm3 (range 0–1424) and 11% had CD4+ cell counts less than 200 cells per mm3. 16% of participants had baseline viral loads greater than 100,000 copies per mL.
In Trial 1490, the mean age was 37 years (range 18–77), 88% were male, 59% were White, 31% were Black, and 3% were Asian. 25% of patients identified as Hispanic/Latino. The mean baseline plasma HIV-1 RNA was 4.4 log10 copies/mL (range 2.3–6.6). The mean baseline CD4+ cell count was 456 cells per mm3 (range 2–1636) and 12% had CD4+ cell counts less than 200 cells per mm3. 19% of participants had baseline viral loads greater than 100,000 copies per mL.
In both trials, participants were stratified by baseline HIV-1 RNA (less than or equal to 100,000 copies per mL, greater than 100,000 copies per mL to less than or equal to 400,000 copies per mL, or greater than 400,000 copies per mL), by CD4 count (less than 50 cells per mm3, 50-199 cells per mm3, or greater than or equal to 200 cells per mm3), and by region (US or ex-US).
Treatment outcomes of Trials 1489 and 1490 through Week 144 are presented in Table 14.

* Week 144 window was between Day 967 and 1050 (inclusive).
† Includes participants who had ≥ 50 copies/mL in the Week 144 window; participants who discontinued early due to lack or loss of efficacy; participants who discontinued for reasons other than an adverse event (AE), death or lack or loss of efficacy and at the time of discontinuation had a viral value of ≥ 50 copies/mL.
‡ Includes participants who discontinued due to AE or death at any time point from Day 1 through the time window if this resulted in no virologic data on treatment during the specified window.
§ Includes participants who discontinued for reasons other than an AE, death, or lack or loss of efficacy, e.g., withdrew consent, loss to follow-up, etc.
Treatment outcomes were similar across subgroups by age, sex, race, baseline viral load, and baseline CD4+ cell count.
In Trials 1489 and 1490, the mean increase from baseline in CD4+ count at Week 144 was 299 and 317 cells per mm3 in the BIKTARVY and ABC/DTG/3TC groups, respectively, and 278 and 289 cells per mm3 in the BIKTARVY and DTG + FTC/TAF groups, respectively.
Use of BIKTARVY in those with an antiretroviral treatment history and not virologically suppressed is supported by a scientific rationale that this population is expected to have similar virologic response rates to those with no history of antiretroviral treatment provided that the virus is susceptible to the individual components of the regimen. Because limited clinical trial data are available supporting the efficacy of BIKTARVY in patients with baseline INSTI resistance substitutions, this indication states use in individuals with an antiretroviral treatment history and who are not virologically suppressed with no evidence of known or suspected substitutions associated with resistance to the INSTI class, rather than only to bictegravir. Additionally, this indication states the individuals should have no known or suspected substitutions associated with resistance to emtricitabine, or tenofovir [see Clinical Studies (14.2 and 14.5)].
In Trial 1844, the efficacy and safety of switching from a regimen of DTG + ABC/3TC or ABC/DTG/3TC to BIKTARVY were evaluated in a randomized, double-blind trial of virologically-suppressed (HIV-1 RNA less than 50 copies per mL) HIV-1 infected adults (N=563, randomized and dosed). Participants must have been stably suppressed (HIV-1 RNA less than 50 copies per mL) on their baseline regimen for at least 3 months prior to trial entry and had no history of treatment failure. Participants were randomized in a 1:1 ratio to either switch to BIKTARVY (containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF) at baseline (N=282), or stay on their baseline antiretroviral regimen (N=281). Participants had a mean age of 45 years (range 20–71), 89% were male, 73% were White, and 22% were Black. 17% of participants identified as Hispanic/Latino. The mean baseline CD4+ cell count was 723 cells per mm3 (range 124–2444).
In Trial 1878, the efficacy and safety of switching from either ABC/3TC or FTC/TDF (200/300 mg) plus ATV or DRV (given with either cobicistat or ritonavir) to BIKTARVY (containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF) were evaluated in a randomized, open-label study of virologically-suppressed HIV-1 infected adults (N=577, randomized and dosed). Participants must have been stably suppressed on their baseline regimen for at least 6 months, must not have been previously treated with any INSTI, and had no history of treatment failure. Participants were randomized in a 1:1 ratio to either switch to BIKTARVY (N=290) or stay on their baseline antiretroviral regimen (N=287). Participants had a mean age of 46 years (range 20–79), 83% were male, 66% were White, and 26% were Black. 19% of participants identified as Hispanic/Latino. The mean baseline CD4+ cell count was 663 cells per mm3 (range 62–2582). Participants were stratified by prior treatment regimen. At screening, 15% of participants were receiving ABC/3TC plus ATV or DRV (given with either cobicistat or ritonavir) and 85% of participants were receiving FTC/TDF plus ATV or DRV (given with either cobicistat or ritonavir).

In Trial 1844, treatment outcomes between treatment groups were similar across subgroups by age, sex, race, and region. The mean change from baseline in CD4+ count at Week 48 was -31 cells per mm3 in participants who switched to BIKTARVY and 4 cells per mm3 in participants who stayed on ABC/DTG/3TC.
In Trial 1878, treatment outcomes between treatment groups were similar across subgroups by age, sex, race, and region. The mean change from baseline in CD4+ count at Week 48 was 25 cells per mm3 in patients who switched to BIKTARVY and 0 cells per mm3 in patients who stayed on their baseline regimen.
In Trial 4030, the efficacy and safety of switching from DTG plus either FTC/TAF or FTC/TDF to BIKTARVY (containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF) were evaluated in a randomized, double-blind study of virologically suppressed HIV-1 infected adults. Participants must have been stably suppressed (HIV-1 RNA less than 50 copies/mL) on their baseline regimen for at least 6 months (if documented or suspected NRTI resistance), or at least 3 months (if no documented or suspected NRTI resistance) prior to trial entry. Participants were randomized to switch to BIKTARVY (N=284) or to continue their prior treatment regimen, DTG+ F/TAF (N=281). The primary endpoint was the proportion of participants with HIV-1 RNA ≥ 50 copies/mL at Week 48. At Week 48 the proportion of participants with HIV-1 RNA ≥50 copies/mL was 0.4% (1/284) in the BIKTARVY group and 1.1% (3/281) in the DTG+F/TAF group (difference -0.7% [95%CI: -2.8%, 1.0%]).
Of the participants receiving BIKTARVY, 47 had HIV-1 with pre-existing M184V or I resistance substitutions (M184M/V, M184M/I, M184V/I, M184V) in HIV-1 RT. Eighty-nine percent (42/47) of participants with M184V or I remained suppressed (HIV-1 RNA < 50 copies/mL) and 11% (5/47 participants) did not have virologic data at the Week 48 timepoint due to study drug discontinuation.
In Trial 1825, an open-label single arm trial, the efficacy, safety, and pharmacokinetics of FTC and TAF (components of BIKTARVY) were evaluated in virologically-suppressed adults with ESRD (estimated creatinine clearance of less than 15 mL/min) on chronic hemodialysis treated with FTC+TAF in combination with elvitegravir and cobicistat as a fixed-dose combination tablet for 96 weeks (N=55). In an extension phase of Trial 1825, 10 virologically-suppressed participants switched to BIKTARVY and all participants remained virologically suppressed (HIV-1 RNA < 50 copies/mL) for 48 weeks.
In Trial 4449, the efficacy and safety of switching from a stable antiretroviral regimen to BIKTARVY (containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF) were evaluated in an open-label, single arm trial of virologically-suppressed (HIV-1 RNA less than 50 copies per mL) HIV-1 infected adults aged 65 years and over (N=86). Participants treated with BIKTARVY had a mean age of 70 years (range: 65 to 80). The primary endpoint was the proportion of participants with HIV RNA > 50 copies/mL at Week 48. No participants had HIV RNA > 50 copies/mL. Ninety-one percent (78/86) of participants remained suppressed (HIV-1 RNA < 50 copies/mL) at Week 48. Eight participants did not have virologic data at the Week 48 timepoint due to discontinuation or missing data.
In Trial 1474, an open-label, single arm trial the efficacy, safety, and pharmacokinetics of BIKTARVY in pediatric participants with HIV-1 were evaluated in virologically-suppressed adolescents between the ages of 12 to less than 18 years weighing at least 35 kg (N=50), in virologically-suppressed children between the ages of 6 to less than 12 years weighing at least 25 kg (N=50), and in virologically-suppressed children at least 2 years of age and weighing at least 14 to less than 25 kg (N=22).
Cohort 1: Virologically-suppressed adolescents (12 to less than 18 years; at least 35 kg)
Participants in cohort 1 treated with BIKTARVY (containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF) once daily had a mean age of 14 years (range: 12 to 17) and a mean baseline weight of 51.7 kg (range: 35 to 123), 64% were female, 27% were Asian and 65% were black. At baseline, median CD4+ cell count was 750 cells per mm3 (range: 337 to 1207), and median CD4+% was 33% (range: 19% to 45%).
After switching to BIKTARVY, 98% (49/50) of participants in cohort 1 remained suppressed (HIV-1 RNA < 50 copies/mL) at Week 48. The mean change from baseline in CD4+ cell count at Week 48 was -22 cells per mm3.
Cohort 2: Virologically-suppressed children (6 to less than 12 years; at least 25 kg)
Participants in cohort 2 treated with BIKTARVY once daily had a mean age of 10 years (range: 6 to 11) and a mean baseline weight of 31.9 kg (range: 25 to 69), 54% were female, 22% were Asian and 72% were black. At baseline, median CD4+ cell count was 898 cells per mm3 (range 390 to 1991) and median CD4+% was 37% (range: 19% to 53%).
After switching to BIKTARVY (containing 50 mg of BIC, 200 mg of FTC, and 25 mg of TAF), 100% (50/50) of participants in cohort 2 remained suppressed (HIV-1 RNA < 50 copies/mL) at Week 24. The mean change from baseline in CD4+ cell count at Week 24 was -24 cells per mm3.
Cohort 3: Virologically-suppressed children (at least 2 years; at least 14 to less than 25 kg)
Participants in cohort 3 treated with BIKTARVY (containing 30 mg of BIC, 120 mg of FTC, and 15 mg of TAF) once daily had a mean age of 5 years (range: 3 to 9) and a mean baseline weight of 18.8 kg (range: 14 to 24), 50% were female, 23% were Asian and 73% were black. At baseline, the mean CD4+ cell count (SD) was 1104 (440), and the mean CD4% (SD) was 33.4% (6.0%).
After switching to BIKTARVY, 91% (20/22) of participants in cohort 3 remained suppressed (HIV-1 RNA < 50 copies/mL) at Week 24. HIV-1 RNA was not collected at Week 24 for 2 participants because of COVID-19 pandemic-related study disruption. The mean change from baseline to Week 24 in CD4+ cell count (SD) was −126 (264.2) cells per mm3 ; and the mean change in CD4% (SD) from baseline to Week 24 was 0.2% (4.4%).

Advise the patient to read the FDA-approved patient labeling (Patient Information).
Post-treatment Acute Exacerbation of Hepatitis B in Participants with HBV
Severe acute exacerbations of hepatitis B have been reported in patients with HBV and HIV-1 who have discontinued products containing FTC and/or TDF, and may likewise occur with discontinuation of BIKTARVY [see Warnings and Precautions (5.1)]. Advise the patient to not discontinue BIKTARVY without first informing their healthcare provider.
Drug Interactions
BIKTARVY may interact with certain 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)].
Immune Reconstitution Syndrome
Advise patients to inform their healthcare provider immediately of any symptoms of infection, as in some patients with advanced HIV infection (AIDS), signs and symptoms of inflammation from previous infections may occur soon after anti-HIV treatment is started [see Warnings and Precautions (5.3)].
Renal Impairment
Advise patients to avoid taking BIKTARVY with concurrent or recent use of nephrotoxic agents. Postmarketing cases of renal impairment, including acute renal failure, have been reported [see Warnings and Precautions (5.4)].
Lactic Acidosis and Severe Hepatomegaly
Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, have been reported with use of drugs similar to BIKTARVY. Advise patients that they should stop BIKTARVY if they develop clinical symptoms suggestive of lactic acidosis or pronounced hepatotoxicity [see Warnings and Precautions (5.5)].
Missed Dosage
Inform patients that it is important to take BIKTARVY on a regular dosing schedule with or without food and to avoid missing doses as it can result in development of resistance [see Dosage and Administration (2.2)].
Tablet Splitting
Advise caregivers that, for children unable to swallow a whole tablet, the tablet can be split and each part taken separately as long as all parts are ingested within approximately 10 minutes [see Dosage and Administration (2.3)].
Pregnancy Registry
Inform patients that there is an antiretroviral pregnancy registry to monitor fetal outcomes of pregnant individuals exposed to BIKTARVY [see Use in Specific Populations (8.1)].
Lactation
Inform individuals with HIV-1 that the potential risks of breastfeeding include: (1) HIV-1 transmission to infants without HIV-1, (2) developing viral resistance in infants with HIV-1, and (3) adverse reactions in a breastfed infant similar to those seen in adults [see Use in Specific Populations (8.2)].
