Abstract
PURPOSE: The purpose of this study is to assess postmarketing safety and tolerability of Stribild (elvitegravir [EVG]/cobicistat [COBI]/tenofovir disoproxil fumarate [TDF]/emtricitabine [FTC]). METHODS: A retrospective, pharmacoepidemiologic study in 2 outpatient HIV clinics in the Southeast United States was conducted among adults receiving EVG/COBI/TDF/FTC. We evaluated incidence and treatment-related adverse events, including change in serum creatinine (SCr). RESULTS: Patients were primarily treatment experienced (n = 173, 60%), African American (n = 210, 73%), and males (n = 187, 65%). One hundred ninety-five (68%) patients had any increase in SCr, and 65 (23%) had an increase of ≥0.3 mg/dL. Mean SCr change from baseline to peak was 0.2 mg/dL. Being treatment experienced (odds ratio [OR] = 2.21, 95% confidence interval [CI]: 1.12-4.38) was associated with SCr ≥0.3 mg/dL, while body mass index ≥30 kg/m(2) (OR = 0.41, 95% CI: 0.18-0.93) was protective. Twenty (7%) patients discontinued therapy, 3 due to acute kidney injury. CONCLUSION: Our results demonstrate limited adverse events and low discontinuation rates associated with EVG/COBI/TDF/FTC.
