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 living 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...

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...

The EMERALD Study is a Phase III, open-label, noninferiority study in which 1,141 patients with stable HIV suppression on a regimen comprising a boosted protease inhibitor plus TDF/FTC were randomized (2:1) to either switch to an investigational single-tablet regimen containing...

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...

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...

This publication presents the results of San Francisco General Hospital's Ward 86 pilot study of immediate ART initiation. This RAPID program systematically offered ART to patients upon diagnosis of HIV; patients were referred from HIV testing sites in San Francisco. Of the 39 patients who...

We know that very early treatment in acute HIV infection decreases HIV RNA; this study shows it also greatly decreases proviral DNA (and reservoir size). Researchers investigated 2 small cohorts of patients in Thailand with acute (and very early) HIV infection, 1 untreated and 1 treated with ART...

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...
