Why two NDCs? The FDA registers this code as 50090-6247-0 — a 5-4-1 layout, and that's what's printed on the package and shown on DailyMed. For insurance claims, every NDC is standardized to a uniform 11-digit 5-4-2 format by adding a zero to the package segment → 50090-6247-00. Same drug, same package — only the format differs.

📖 What it is MedlinePlus · NLM

The combination of bictegravir, emtricitabine, and tenofovir AF is used to treat human immunodeficiency virus (HIV) infection. Bictegravir is in a class of medications called integrase strand transfer inhibitors (INSTIs). Emtricitabine and tenofovir AF are in a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs). The combination of bictegravir, emtricitabine, and tenofovir AF works by decreasing the amount of HIV in the body. Although bictegravir, emtricitabine, and tenofovir AF will not cure HIV, these medications may decrease your chance of developing acquired imm...

10 inactive ingredients listed in the exact product block matched to this NDC.

Where does this data come from?
Data sourced from official FDA Structured Product Labeling (SPL) via DailyMed — ingredient classCode="IACT" elements from the exact product block matched by this NDC. Label-section narrative from DailyMed / the openFDA label index is shown separately when available.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer eachPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · Q2 2026 $135.82 $4,074.70 / 30 tablets
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

We did not find an FDA-approved generic match for this exact strength, form and route. Patent/protection dates below may affect future generic timing.

🛡️ Latest patent/protection date listed: FDA patent/protection data lists protections through Nov 2036. This may affect when a full generic version becomes widely available, but it is not a guaranteed launch date.
📅 FDA approved Feb 7, 2018 RLD RS ⏳ ~10.1 yr to latest listed protection

Why the date isn’t exact: Generic timing can change because patents may be challenged, settled, licensed, added, removed, or worked around with a narrower label — and FDA approval does not always mean a pharmacy can get the generic today.

LOE
Substance patent Formulation patent Method-of-use patent Exclusivity Pediatric +6mo
🏛️FDA exclusivity
FDA-granted marketing protection. It’s separate from patents and may be shorter than patent protection.
🧪Product / substance patents
Patents covering the active ingredient, product, formulation, or related drug features.
🎯Method-of-use patents
Patents covering specific approved uses. These can sometimes be carved out with a “skinny label,” but not always.
🛈 What do these terms mean?
Patent
Legal protection listed in the Orange Book that may delay generic approval or launch. Issued by the U.S. Patent & Trademark Office.
Substance patent
Covers the active drug molecule itself — the hardest to design around. A generic generally can’t launch until it expires.
Formulation (product) patent
Covers a specific formulation or dosage form. A generic can sometimes work around it with a different formulation.
Method-of-use patent
A patent covering one specific approved use of the drug — not necessarily the whole molecule. A generic can sometimes launch with a “skinny label” that carves out the protected use and keeps the others.
Skinny label
A generic label that omits a still-patented use when the FDA allows it — letting a generic reach the market for the unprotected uses.
Exclusivity
FDA-granted marketing protection, separate from patents — e.g. 5-yr new chemical entity, 7-yr orphan drug, or a +6-month pediatric extension.
Paragraph IV
A generic applicant’s formal challenge to a listed patent. It can potentially lead to earlier generic entry, but often involves litigation or a settlement.
RLD / RS
Reference Listed Drug — the brand product the FDA uses as the reference for generic applications. Reference Standard — the product the FDA expects generics to compare against in bioequivalence testing.
TE / AB rating
FDA therapeutic-equivalence rating. An AB rating generally means the FDA considers a generic therapeutically equivalent to — and substitutable for — the brand.
LOE (loss of exclusivity)
The latest patent or exclusivity currently listed — the loss-of-exclusivity / latest-listed-protection date shown on this page. Paragraph-IV challenges and settlements can move the real date earlier; FDA approval and a manufacturer’s decision to market can move it later.

Built from the FDA Orange Book. The bars above are scaled to each protection’s expiry; the red LOE marker is the last one to lapse.

Common questions
Is there a generic version of BIKTARVY 50-200-25 MG TABLET?
No FDA-approved generic equivalent is currently listed in the FDA Orange Book for BIKTARVY 50-200-25 MG TABLET. Based on the patents and exclusivity currently listed, the Orange Book estimate is that full-label generic entry may be delayed until Nov 2036 — an estimate, not a guaranteed launch date.
The FDA approved a generic — why can’t I get it at my pharmacy yet?
FDA approval and pharmacy availability are two different things. The FDA can approve a generic years before it actually reaches pharmacies, because the brand company may still hold patents or have a settlement that delays the launch. A manufacturer also has to choose to make and sell it, and have supply ready. So a drug can be “FDA-approved generic exists” and still be brand-only at the counter today.
Why do different websites show different generic release dates?
Generic availability is not based on one single date. Some sources use the first exclusivity expiration, some use the last product patent, and others use the latest method-of-use patent. Patent challenges, settlements, licenses, and label carve-outs can also change the real-world launch date. This page shows the underlying Orange Book dates so you can see why estimates may differ.
What does “FDA listed” mean?
It means the product appears in the FDA’s official NDC directory. That’s a good sign a product exists and is intended for the U.S. market, but on its own it does not confirm a pharmacy can fill it today. Where we have recent retail pricing data (NADAC) for a product, we label it “Availability likely” instead.
What does a patent or protection date mean here?
It’s the latest date currently listed in the FDA Orange Book for a patent or exclusivity on the brand product. It can affect when a full generic version becomes widely available — but it is not a guaranteed generic launch date. Generics sometimes arrive earlier (through a settlement or patent challenge) or later (a manufacturer still has to make and sell one).
What does “current Orange Book estimate” mean?
It means we are using the latest patent and exclusivity dates currently listed in the FDA Orange Book. It is not a guaranteed launch date.
Can a generic come out before the last patent expires?
Sometimes. A generic company may challenge a patent, settle with the brand manufacturer, receive a license, or obtain approval with a narrower label that avoids a patented use. In other cases, the last listed protection may delay full-label generic competition.
Can a generic come out after the listed dates?
Yes. Even after patents or exclusivity expire, a generic still needs FDA approval and a manufacturer must choose to market it. Supply, litigation, business decisions, or regulatory issues can delay actual availability.
What is the difference between patents and exclusivity?
Patents are legal protections usually issued by the U.S. Patent and Trademark Office. FDA exclusivity is marketing protection granted by the FDA. They are separate, and either one can affect generic timing.
Why are there multiple patent dates?
One drug can have several patents covering different things: the active ingredient, a formulation, a manufacturing process, or a specific approved use. That is why a page may show several expiration dates instead of one simple generic date.
Built from FDA Orange Book patent and exclusivity data. Dates are refreshed from public FDA data when available; the marker is max(latest patent expiry, latest exclusivity expiry). Paragraph-IV settlements and first-filer 180-day exclusivity can shift the real date; a method-of-use patent may allow an earlier skinny-label generic for non-protected indications. Generic launch timing is an estimate, not a guarantee.
Where does this data come from?
Patents and exclusivity from the FDA Orange Book (small-molecule drugs), refreshed from public FDA data. Generic launch timing is an estimate, not a guarantee.

📊 Medicare Part D spend CMS · PART D · 2026 (Q1)

Medicare Part D (outpatient prescription) spending for Biktarvy — the program that covers self-administered drugs. 1 manufacturer.
⚠️ Drug-level data: CMS publishes Part D spending by drug, not by NDC — these figures combine every manufacturer, strength and package size sold under the name Biktarvy. That’s a different level of aggregation than the Medicaid card above, which is specific to this exact 11-digit NDC (pack size included), so the two aren’t directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 50090-6247-0, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 50090-6247-00, written without dashes as 50090624700. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 50090-6247-00, the first segment (50090) is the labeler code FDA assigned to A-S Medication Solutions; the middle segment (6247) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (00) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by A-S Medication Solutions. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
A-S Medication Solutions is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.
Where does this data come from?

⚠️ Warnings and Cautions ~3 min read ▾

5 WARNINGS AND PRECAUTIONS Immune reconstitution syndrome: May necessitate further evaluation and treatment. ( 5.3 ) New onset or worsening renal impairment: Assess serum creatinine, estimated creatinine clearance, urine glucose and urine protein when initiating BIKTARVY and during therapy as clinically appropriate in all patients. Also assess serum phosphorus in patients with chronic kidney disease.

( 5.4 ) Lactic acidosis/severe hepatomegaly with steatosis: Discontinue treatment in patients who develop symptoms or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity. ( 5.5 )

5.1Severe Acute Exacerbation of Hepatitis B in Patients Coinfected with HIV-1 and HBV Patients with HIV-1 should be tested for the presence of chronic hepatitis B virus (HBV) infection 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 who are coinfected with HIV-1 and HBV and have discontinued products containing FTC and/or tenofovir disoproxil fumarate (TDF), and may occur with discontinuation of BIKTARVY.

Patients coinfected 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.

5.2Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions 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) ]: Loss of therapeutic effect of BIKTARVY and possible development of resistance. Possible clinically significant adverse reactions from greater exposures of concomitant drugs. 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.

5.3Immune Reconstitution Syndrome 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.

5.4New Onset or Worsening Renal Impairment 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 wh…

6 ADVERSE REACTIONS The following adverse reactions are discussed in other sections of the labeling: Severe Acute Exacerbations of Hepatitis B [see Warnings and Precautions (5.1) ] . Immune Reconstitution Syndrome [see Warnings and Precautions (5.3) ] . New Onset or Worsening Renal Impairment [see Warnings and Precautions (5.4) ].

Lactic Acidosis/Severe Hepatomegaly with Steatosis [see Warnings and Precautions (5.5) ]. Most common adverse reactions (incidence greater than or equal to 5%, all grades) are diarrhea, nausea, and headache.

6.1Clinical 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 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 HIV-1 infected adult subjects with no antiretroviral treatment history through Week 144.

After Week 144, subjects received open-label BIKTARVY in an optional extension phase for an additional 96 weeks (end of study). A total of 634 and 1025 subjects 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 subjects in the BIKTARVY group in either Trial 1489 or Trial 1490 were diarrhea, nausea, and headache.

The proportion of subjects 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. Table 1 Adverse Reactions 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 subjects treated with BIKTARVY. (All Grades) Reported in ≥ 2% of HIV-1 Infected Adults with No Antiretroviral Treatment History Receiving BIKTARVY in Trials 1489 or 1490 (Week 144 analysis) 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% Additional adverse reactions (all Grades) occurring in less than 2% of subjects 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 subjects administered BIKTARVY; these events occurred primarily in subjects 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 subjects administered BIKTARVY in the Week 144 analysis.

Clinical Trials in Virologically Suppressed Adults The safety of BIKTARVY in virologically-suppressed adults was based on Week 48 data from 282 subjects in a randomized, double-blind, active-controlled trial (Trial 1844) in which virologically-suppressed subjects were switched from either DTG + ABC/3TC or ABC/DTG/3TC to BIKTARVY; Week 48 data from 290 subjects in an open-label, active-controlled trial in which virologically-suppressed subjects were switched from a regimen co…

7 DRUG INTERACTIONS Because BIKTARVY is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended. ( 7.1 ) Consult the Full Prescribing Information prior to and during treatment for important drug interactions. ( 4 , 5.2 , 7 , 12.3 )

7.1Other Antiretroviral Medications 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.

7.2Potential for BIKTARVY to Affect Other Drugs 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 ).

7.3Potential Effect of Other Drugs on One or More Components of BIKTARVY 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 ).

7.4Drugs Affecting Renal Function 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) ] .

7.5Established and Potentially Significant Drug Interactions 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) ] .

8 USE IN SPECIFIC POPULATIONS Pediatrics: Not recommended for patients weighing less than 14 kg. ( 8.4 )

8.1Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women 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 There are insufficient human data on the use of BIKTARVY during pregnancy to inform a drug-associated risk of birth defects and miscarriage.

Dolutegravir, another integrase inhibitor, has been associated with neural tube defects (NTDs) (see Data ) . Discuss the benefit-risk of using BIKTARVY with individuals of childbearing potential, particularly if pregnancy is being planned. BIKTARVY use during pregnancy has been evaluated in a limited number of women reported to the APR; consequently, there are insufficient BIC data from the APR to adequately assess the risk of major birth defects.

Reports of pregnant individuals treated with other drug products containing TAF or FTC 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 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%. 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 Prospective reports from the APR of overall major birth defects in pregnancies exposed to the components of BIKTARVY are compared with a U.S. background major birth defect rate. Methodological limitations of the APR include the use of MACDP as the external comparator group.

The MACDP population is not disease-specific, evaluates women and infants from a limited geographic area, and does not include outcomes for births that occurred at less than 20 weeks gestation. Bictegravir (BIC): Data from an observational study in Botswana showed that dolutegravir, another integrase inhibitor, was associated with increased risk of neural tube defects when administered at the time of conception and in early pregnancy. Data available to date from other sources including the APR, clinical trials, and postmarketing data are insufficient to address this risk with BIC.

There are an insufficient number of reports to the APR to adequately assess the risk of major birth defects associated with BIC exposure. The APR has received prospective reports of 3 birth defects among 100 (3.0%) first trimester exposures to BIC-containing regimens during pregnancy resulting in live births. No birth defects were reported among 40 exposures during the second/third trimester.

Emtricitabine (FTC): Based on prospective reports to the APR of over 5,400 exposures to FTC-containing regimens during pregnancy resulting in live births (including over 3,900 exposed in the first trimester and over 1,500 exposed in the second/third trimester), the prevalence of birth defects in live births was 2.6% (95% CI: 2.2% to 3.2%) and 2.7…

🧒 Pediatric Use ~1 min read ▾

8.4Pediatric Use 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: who have no antiretroviral treatment history or to replace the current antiretroviral regimen in those who are virologically-suppressed (HIV-1 RNA less than 50 copies per mL) on a stable antiretroviral regimen with no known or suspected resistance to bictegravir or tenofovir [see Indications and Usage (1) , and Dosage and Administration (2.2 , 2.3) ] .

Use of BIKTARVY in pediatric patients weighing at least 14 kg is supported by the following: trials in adults [see Clinical Studies (14.1) ] an open-label trial in three age-based cohorts of virologically-suppressed pediatric subjects [see Clinical Studies (14.4) ] Cohort 1: 12 to less than 18 years of age and weighing at least 35 kg receiving BIKTARVY through Week 48 (N=50), Cohort 2: 6 to less than 12 years of age and weighing at least 25 kg receiving BIKTARVY through Week 24 (N=50), and Cohort 3: at least 2 years of age and weighing at least 14 to less than 25 kg through Week 24 (N=22).

No pediatric subjects 2 years of age were enrolled; of the 6 pediatric subjects who were 3 years of age at enrollment, 3 subjects weighed between 14 to less than 15 kg. The safety and efficacy of BIKTARVY in these pediatric subjects 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.

🧓 Geriatric Use 134 words ▾

8.5Geriatric Use Clinical trials in virologically-suppressed subjects (Trials 4449, 1844, and 1878) included 111 subjects aged 65 years and over who received BIKTARVY, including 86 patients from an open-label, single-arm trial of subjects 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 subjects 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.

🆘 Overdosage 108 words ▾

10 OVERDOSAGE 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%.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action BIKTARVY is a fixed dose combination of antiretroviral drugs bictegravir (BIC), emtricitabine (FTC), and tenofovir alafenamide (TAF) [see Microbiology (12.4) ] .

12.2Pharmacodynamics Cardiac Electrophysiology In a thorough QT/QTc trial in 48 healthy subjects, 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 subjects, 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 subjects 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).

12.3Pharmacokinetics 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.

📋 Description ~2 min read ▾

11 DESCRIPTION BIKTARVY (bictegravir, emtricitabine, and tenofovir alafenamide) is a fixed dose combination tablet containing bictegravir (BIC), emtricitabine (FTC), and tenofovir alafenamide (TAF) for oral administration. BIC is an integrase strand transfer inhibitor (INSTI). FTC, a synthetic nucleoside analog of cytidine, is an HIV nucleoside analog reverse transcriptase inhibitor (HIV NRTI).

TAF, an HIV NRTI, is converted in vivo to tenofovir, an acyclic nucleoside phosphonate (nucleotide) analog of adenosine 5′-monophosphate. BIKTARVY tablets are available in two dose strengths: 50 mg/200 mg/25 mg tablet containing 50 mg of BIC (equivalent to 52.5 mg of bictegravir sodium), 200 mg of FTC, and 25 mg of TAF (equivalent to 28 mg of tenofovir alafenamide fumarate). 30 mg/120 mg/15 mg tablet containing 30 mg of BIC (equivalent to 31.5 mg of bictegravir sodium), 120 mg of FTC, and 15 mg of TAF (equivalent to 16.8 mg of tenofovir alafenamide fumarate).

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. Bictegravir: The chemical name of bictegravir sodium is 2,5-Methanopyrido[1',2':4,5]pyrazino[2,1- b ][1,3]oxazepine-10-carboxamide, 2,3,4,5,7,9,13,13a-octahydro-8-hydroxy-7,9-dioxo- N -[(2,4,6-trifluorophenyl)methyl]-, sodium salt (1:1), (2 R ,5 S ,13a R )-.

Bictegravir sodium has a molecular formula of C 21 H 17 F 3 N 3 NaO 5 and a molecular weight of 471.4 and has the following structural formula: Bictegravir sodium is an off-white to yellow solid with a solubility of 0.1 mg per mL in water at 20 °C. Chemical Structure Emtricitabine: The chemical name of FTC is 4-amino-5-fluoro-1-(2 R -hydroxymethyl-1,3-oxathiolan-5 S -yl)-(1H)-pyrimidin-2-one. FTC is the (-)enantiomer of a thio analog of cytidine, which differs from other cytidine analogs in that it has a fluorine in the 5 position.

FTC has a molecular formula of C 8 H 10 FN 3 O 3 S and a molecular weight of 247.2 and has the following structural formula: FTC is a white to off-white powder with a solubility of approximately 112 mg per mL in water at 25 °C. Chemical Structure Tenofovir alafenamide: The chemical name of tenofovir alafenamide fumarate drug substance is L-alanine, N -[( S )-[[(1 R )-2-(6-amino-9 H -purin-9-yl)-1-methylethoxy]methyl]phenoxyphosphinyl]-, 1-methylethyl ester, (2 E )-2-butenedioate (2:1). Tenofovir alafenamide fumarate has an empirical formula of C 21 H 29 O 5 N 6 P∙½(C 4 H 4 O 4 ) and a formula weight of 534.5 and has the following structural formula: 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.

💬 Information for Patients ~2 min read ▾

17 PATIENT COUNSELING INFORMATION Advise the patient to read the FDA-approved patient labeling (Patient Information). Post-treatment Acute Exacerbation of Hepatitis B in Patients with HBV Coinfection Severe acute exacerbations of hepatitis B have been reported in patients who are coinfected with HBV and HIV-1 and 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 women exposed to BIKTARVY [see Use in Specific Populations (8.1) ]. Lactation Inform individuals with HIV-1 infection that the 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 [see Use in Specific Populations (8.2) ].
