Abstract:
In HIV-1-infected treatment-naive patients with mild-to-moderate renal impairment [creatinine clearance (CrCl): 50-89 mL/min], elvitegravir/cobicistat/emtricitabine/tenofovir DF (STB, n = 33) achieved high rates of virologic success (78.8%; 95% confidence interval: 61.1% to 91.0%) and was well tolerated through week 48. Four patients discontinued study drug due to an adverse event and none due to proximal renal tubulopathy. As expected, decreases in CrCl were noted as early as week 2, after which they stabilized. The renal safety profile of STB in patients from this study is consistent with the long-term experience in a large number of patients with CrCl ≥70 mL/min.

Renal Failure: Dose Adjustments
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...
