Gilead Announces New Data on Biktarvy® for the Treatment of HIV in Black Americans
– BRAAVE 2020 Study Demonstrates Non-Inferiority of Biktarvy for the Treatment of HIV in Black Americans Who Are Virologically Suppressed, Including Patients With a History of Treatment Failure or Pre-Existing Resistance –
– Additional Analysis Shows Potential of Biktarvy to Be an Important Treatment Option for People Living With HIV Who are Virologically Suppressed and Have End Stage Renal Disease Requiring Hemodialysis –
BRAAVE 2020 is a Phase 3 clinical trial evaluating the specific treatment responses of virologically suppressed adults living with HIV who self-identified as Black or
“Black and African Americans in this country have the highest rates of new HIV infections every year compared to other races. Adding to that burden are other inequalities such as lack of health insurance, difficulties navigating the healthcare system, and poverty; all of which contribute to higher rates of drug resistance,” explained

Gilead presented additional Biktarvy clinical development program data at IDWeek 2020, including 48-week findings from a Phase 3, open-label, 48-week extension study, which found that a once-daily regimen of Biktarvy maintained virologic suppression in people living with HIV on chronic hemodialysis. This shows the potential of Biktarvy as an effective treatment option with convenient single tablet regimen dosing that can lessen the burden of complex dose-adjusted regimens that many people living with HIV on hemodialysis require. In addition, Gilead will present findings from an in vitro simulation examining Biktarvy’s effect on drug resistance during short lapses in adherence.
“An HIV treatment clinical trial program that addresses the specific needs of people living with HIV such as disproportionately impacted and underrepresented populations, or those who have specific comorbidities, is central to Gilead’s mission of helping to end the HIV epidemic,” said
Additional data from a late-breaking oral presentation provide important insight on tenofovir alafenamide’s (TAF) impact on weight, further supporting the hypothesis that a switch from tenofovir disoproxil fumarate (TDF) to TAF may result in weight gain because the TDF-induced weight suppression is no longer present. The study evaluated weight change in virologically suppressed people living with HIV on a standard regimen of two NRTIs plus an integrase strand transfer inhibitor (INSTI). After one year, those who switched from TDF to TAF (n=828) and those who switched from abacavir (ABC) to TAF (n=142) experienced a mean unadjusted weight gain of 1.4 kg and 0.2 kg, respectively (p=0.039). In the TDF to TAF switch group, 40% experienced weight gain ≥ 3% compared with 27% of those in the

BOXED WARNING: POST TREATMENT ACUTE EXACERBATION OF HEPATITIS B
- Severe acute exacerbations of hepatitis B have been reported in patients who are coinfected with HIV-1 and HBV and have discontinued products containing emtricitabine (FTC) and/or tenofovir disoproxil fumarate (TDF) and may occur with discontinuation of BIKTARVY. Closely monitor hepatic function with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue BIKTARVY. If appropriate, anti-hepatitis B therapy may be warranted.
- Coadministration: Do not use BIKTARVY with dofetilide or rifampin.
Warnings and precautions:
- Drug interactions: See Contraindications and Drug Interactions sections. Consider the potential for drug interactions prior to and during BIKTARVY therapy and monitor for adverse reactions.
- Immune reconstitution syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported.
- New onset or worsening renal impairment: Cases of acute renal failure and Fanconi syndrome have been reported with the use of tenofovir prodrugs. In clinical trials of BIKTARVY, there have been no cases of Fanconi syndrome or proximal renal tubulopathy (PRT). Do not initiate BIKTARVY in patients with estimated creatinine clearance (CrCl) <30 mL/min. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue BIKTARVY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Renal monitoring: Prior to or when initiating BIKTARVY and during therapy, assess serum creatinine, CrCl, urine glucose, and urine protein in all patients as clinically appropriate. In patients with chronic kidney disease, assess serum phosphorus.
Lactic acidosis and severe hepatomegaly with steatosis: Fatal cases have been reported with the use of nucleoside analogs, including
FTCand TDF. Discontinue BIKTARVY if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity develop, including hepatomegaly and steatosis in the absence of marked transaminase elevations.
- Most common adverse reactions (incidence ≥5%; all grades) in clinical studies through week 144 were diarrhea (6 percent), nausea (6%), and headache (5%).
- Prescribing information: Consult the full prescribing information for BIKTARVY for more information on Contraindications, Warnings, and potentially significant drug interactions, including clinical comments.
- Enzymes/transporters: Drugs that induce P-gp or induce both CYP3A and UGT1A1 can substantially decrease the concentration of components of BIKTARVY. Drugs that inhibit P-gp, BCRP, or inhibit both CYP3A and UGT1A1 may significantly increase the concentrations of components of BIKTARVY. BIKTARVY can increase the concentration of drugs that are substrates of OCT2 or MATE1.
Drugs affecting renal function: Coadministration of BIKTARVY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of
FTCand tenofovir and the risk of adverse reactions.
Dosage and administration:
- Dosage: Patients weighing ≥25 kg: 1 tablet taken once daily with or without food.
- Renal impairment: Not recommended in patients with CrCl <30 mL/min.
- Hepatic impairment: Not recommended in patients with severe hepatic impairment.
- Prior to or when initiating: Test patients for HBV infection.
- Prior to or when initiating, and during treatment: As clinically appropriate, assess serum creatinine, CrCl, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, assess serum phosphorus.
Pregnancy and lactation:
Pregnancy: There is insufficient human data on the use of BIKTARVY during pregnancy. Dolutegravir, another integrase inhibitor, has been associated with neural tube defects. Discuss the benefit-risk of using BIKTARVY during pregnancy and conception. An Antiretroviral Pregnancy Registry (APR) has been established. Available data from the APR for
FTCshows no difference in the rates of birth defects compared with a US reference population.
- Lactation: Women infected with HIV-1 should be instructed not to breastfeed, due to the potential for HIV-1 transmission.
Biktarvy is indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 25 kg who have no antiretroviral (ARV) treatment history or to replace the current ARV regimen in those who are virologically suppressed (HIV-1 RNA <50 copies per mL) on a stable ARV regimen with no history of treatment failure and no known resistance to any component of Biktarvy.
