Laboratory Testing Prior to Initiation and During Treatment with EVOTAZ

Renal Testing

Renal laboratory testing should be performed in all patients prior to initiation of EVOTAZ and continued during treatment with EVOTAZ. Renal laboratory testing should include estimated creatinine clearance, serum creatinine, and urinalysis with microscopic examination. Cobicistat decreases estimated creatinine clearance due to inhibition of tubular secretion of creatinine without affecting actual renal glomerular function.

When coadministering EVOTAZ with tenofovir disoproxil fumarate (tenofovir DF), assess estimated creatinine clearance, urine glucose, and urine protein at baseline and routinely monitor during treatment. In patients with chronic kidney disease, also monitor serum phosphorus.

Hepatic Testing

Hepatic laboratory testing should be performed in patients with underlying liver disease prior to initiation of EVOTAZ and continued during treatment with EVOTAZ.

Recommended Dosage

EVOTAZ is a fixed-dose tablet containing 300 mg of atazanavir and 150 mg of cobicistat. The recommended dosage of EVOTAZ is one tablet taken once daily orally with food in HIV-1-infected treatment-naïve and treatment-experienced:

•
Adult patients
•
Pediatric patients weighing at least 35 kg

Administer EVOTAZ in conjunction with other antiretroviral agents. Dose separation may be required when taken with H2-receptor antagonists or proton-pump inhibitors.

Dosage in Patients with Renal Impairment

EVOTAZ is not recommended in treatment-experienced patients with HIV-1 infection who have end-stage renal disease managed with hemodialysis.

EVOTAZ coadministered with tenofovir DF is not recommended in patients with estimated creatinine clearance below 70 mL/min. Coadministration of EVOTAZ and tenofovir DF in combination with concomitant or recent use of a nephrotoxic agent is not recommended.

Not Recommended in Patients with Any Degree of Hepatic Impairment

EVOTAZ is not recommended in patients with any degree of hepatic impairment.

Not Recommended During Pregnancy

EVOTAZ is not recommended for use during pregnancy and should not be initiated in pregnant individuals due to substantially lower exposures of cobicistat and consequently, lower exposures of atazanavir, during the second and third trimesters. An alternative regimen is recommended for individuals who become pregnant during therapy with EVOTAZ.
