On November 10, 2016, the FDA approved VEMLIDY (tenofovir alafenamide) 25 mg tablets. VEMLIDY is a hepatitis B virus (HBV) nucleoside analog reverse transcriptase inhibitor and is indicated for the treatment of chronic hepatitis B virus infection in adults with compensated liver disease.
Prior to initiation of VEMLIDY, test patients for HIV infection. VEMLIDY alone should not be used in patients with HIV infection. Assess serum creatinine, serum phosphorous, estimated creatinine clearance, urine glucose, and urine protein before initiating VEMLIDY and during therapy in all patients as clinically appropriate.
The recommended dosage is 25 mg (one tablet) taken orally once daily with food
No dosage adjustment of VEMLIDY is required in patients with mild, moderate, or severe renal impairment. VEMLIDY is not recommended in patients with end stage renal disease (estimated creatinine clearance below 15 mL per minute)
No dosage adjustment of VEMLIDY is required in patients with mild hepatic impairment (Child-Pugh A). VEMLIDY is not recommended in patients with decompensated (Child-Pugh B or C) hepatic impairment
WARNINGS AND PRECAUTIONS
HBV and HIV-1 coinfection: VEMLIDY alone is not recommended for the treatment of HIV-1 infection. HIV-1 resistance may develop in these patients.
New onset or worsening renal impairment: Assessment of serum creatinine, serum phosphorus, estimated creatinine clearance, urine glucose, and urine protein is recommended before initiating VEMLIDY therapy and during therapy as clinically appropriate.
ADVERSE REACTIONS
Most common adverse reactions (incidence greater than or equal to 5%, all grades) are headache, abdominal pain, fatigue, cough, nausea, and back pain.
DRUG INTERACTIONS
VEMLIDY is a substrate of P-glycoprotein (P-gp) and BCRP. Drugs that strongly affect P-gp and BCRP activity may lead to changes in VEMLIDY absorption. Consult the full prescribing information prior to and during treatment for potential drug-drug interactions Established and Other Potentially Significant Drug Interactionsa
