TDF/FTC (Truvada) is the only ARV combination currently approved by the FDA for use as preexposure prophylaxis (PrEP). The multinational Phase 3 DISCOVER Study compared the efficacy and safety of TAF/FTC (Descovy) with TDF/FTC, in HIV-uninfected cisgender MSM and transgender women at high risk...

Immediate antiretroviral therapy (ART) refers to starting HIV treatment as soon as possible after the diagnosis of HIV infection, preferably on the first clinic visit (and even on the same day the HIV diagnosis is made). This strategy also is known as "rapid ART," "same-day ART," and "treatment...

The International AIDS Society (IAS)-USA recently released its 2018 HIV treatment and prevention recommendations. The document is particularly notable for its discussion of "When to Start ART."

The IAS-USA recommends "rapid" or immediate start of ART upon diagnosis of HIV, stating that...

Integrase inhibitors have become primary treatment for most people with HIV; however, the impact of newer integrase inhibitors on pregnancy outcomes has not been well described. Researchers for the observational Tsepamo study have been examining birth outcomes in Botswanan women treated with...

Two pharmacokinetic studies from AIDS 2018 help elucidate the disposition of tenofovir alafenamide (TAF) and cobicistat-boosted darunavir during pregnancy.

The IMPAACT P1026s study examined plasma concentrations of TAF with and without cobicistat in 43 pregnant women. For women taking...

PARTNER1, whose results were reported last year,(1) was one of the studies that supported current efforts to promote the growing scientific consensus supporting "Treatment as Prevention" (TasP) or Undetectable = Untransmittable (U=U).

PARTNER1 evaluated HIV transmission risk in a European...

The U.S. Food and Drug Administration has given approval to a coformulation of darunavir 800 mg/cobicistat 150 mg/emtricitabine 200 mg/tenofovir alafenamide (TAF) 10 mg, to be marketed under the brand name Symtuza. DRV/COBI/FTC/TAF constitutes a complete regimen for patients with susceptible HIV...

Release from correctional settings is a high-stakes time for persons with HIV, as it is for those with other health issues. People with substance use disorders often relapse, and those with HIV often stop ART and do not engage in HIV care, increasing the risk of declines in...

Bictegravir (BIC), a new integrase inhibitor, was recently approved by the FDA for use in a single-pill coformulation with TAF/FTC (brand name: Biktarvy) as initial therapy and as a switch regimen for patients who are already on a suppressive ART regimen and who have no history of...

The availability of ART immediately after the diagnosis of HIV offers many possible benefits, including earlier engagement in care and earlier HIV suppression, which may result in personal and public health benefits. Based on randomized clinical trials done in developing-world settings, the...

Treatment of tuberculosis (TB) in HIV-infected persons remains challenging, in part because of drug interactions between rifampin and some ARVs that may compromise antiretroviral therapy (ART). Three studies presented at CROI provide clinicians with additional guidance on how to manage certain...

Doravirine (DOR) is an investigational NNRTI that currently is being developed in a coformulation with TDF and FTC. A Phase 3 comparison of DOR + 2 NRTIs (87% of study subjects were given TDF/FTC) and DRV/r + 2 NRTIs in initial therapy was presented at CROI earlier this year (DRIVE-FORWARD); the...

Bictegravir (BIC) is an investigational integrase inhibitor that is being studied as part of a coformulation with tenofovir alafenamide (TAF) and emtricitabine (FTC). Two Phase 3 trials comparing a single-tablet regimen of BIC/TAF/FTC (50/25/200 mg) with regimens containing dolutegravir (DTG)...

Bictegravir is an investigational integrase inhibitor that is dosed once daily, unboosted. It is active in vitro against many viruses with integrase resistance mutations. A Phase 2 double-blind placebo-controlled study randomized treatment-naive patients (n...

Leading up to this year, some researchers and clinicians had optimistically viewed dolutegravir an invincible ARV, a drug so mighty that it was unlikely to fail, and even more unlikely to be victim to emergent resistance mutations. Two presentations at CROI demonstrated the...

The PARTNER Study, a multisite European study, evaluated rates of HIV transmissions within serodifferent heterosexual and MSM couples (n = 548 and n = 340, respectively, contributed eligible data). The HIV-positive partners were on ART with HIV RNA levels of <200 copies/mL, and the couples...

At the ASM Microbe meeting in June, researchers from Gilead Sciences presented data on use of TDF/FTC (Truvada) PrEP in the United States according to sex and race. They evaluated national pharmacy databases to identify prescriptions of TDF/FTC given for PrEP between January 2012 and September...

Dolutegravir has several characteristics that, in theory, suggest it will not be significantly removed by dialysis: It has a large apparent volume of distribution (17.4 L) and is highly protein bound (98.9%). A small study of 5 HIV-infected patients with end-stage renal disease undergoing...

Three studies presented at the 2016 Conference on Retroviruses and Opportunistic Infections (CROI) explored the pharmacokinetics of antiretrovirals administered during pregnancy. These studies support the use of standard-dose efavirenz, once-daily dolutegravir, and BID ritonavir-boosted...

A pharmacokinetic study presented at the Conference on Retroviruses and Opportunistic Infections in Boston in February evaluated concentrations of tenofovir (TFV) and TFV-diphosphate (DP) in genital and rectal tissue and in anogenital fluid samples after administration of oral tenofovir...

The prevailing opinion among experts regarding the optimal CD4 T-cell count at which to start patients on antiretroviral therapy (ART) has shifted several times during the evolution of HIV treatment. These shifts reflect attempts to strike a balance between preventing HIV-associated illness and...
