US guidelines include Stribild (Quad) as alternative rather than preferred option for treatment naive adults (2012)

Shortly after FDA approval of the new once-daily single-pill formulation of elvitegravir/cobicistat/tenofovir/emtricitabine (Stribild) the US HHS guideline panel issued a statement on how this combination has been assessed in its recommendations for treatment naive adult patients.

The included the recommendation for elvitegravir 150 mg / cobicistat 150 mg / tenofovir 300 mg / emtricitabine 200 mg once daily (with food) as an “alternative” regimen for ART-naive HIV-infected patients with CrCl >70 mL/min. The recommendation was rated BI (moderate strength recomendation, based on results from randomised clinical trials).

Factors behind the decision not to make this a “preferred” option included “a significant potential for drug-drug interactions, the availability of only 48 weeks of safety data, usage limited to individuals with pre-treatment CrCl >70 mL/min, a possible increased risk of proximal renal tubulopathy, limited data in patients with advanced HIV disease and in women, and the need for the drug to be taken with food”.
