PharmGKB gathers information regarding PGx on FDA drug labels from the FDA's "Table of Pharmacogenomic Biomarkers in Drug Labels", and from FDA-approved FDA and EMA-approved (European Medicines Agency) EMA labels brought to our attention. Excerpts from the label and downloadable highlighted label PDFs are manually curated by PharmGKB.

Please note that some drugs may have been removed from or added to the FDA's "Table of Pharmacogenomic Biomarkers in Drug Labels" without our knowledge. We periodically check the table for additions to this table and update PharmGKB accordingly.

There is currently no such list for European drug labels - we are working with the EMA to establish a list of European Public Assessment Reports (EPAR)s that contain PGx information. We are constructing this list by initially searching for drugs for which we have PGx-containing FDA drug labels - of these 44 EMA EPARs were identified and are being curated for pgx information.

We welcome any information regarding drug labels containing PGx information approved by the FDA, EMA or other Medicine Agencies around the world - please contact feedback.

European Medicines Agency (EMA) Label for atazanavir and CYP2C19

Genetic testing recommended

Summary

The EMA European Public Assessment Report (EPAR) for atazanavir (Reyataz) contains pharmacogenetic information related to co-treatment with voriconazole and ritonavir: both atazanavir and voriconazole exposure is expected to be increased in patients who do not have a functional CYP2C19 allele. The EPAR states that at the time of voriconazole treatment, a test for CYP2C19 genotype should be performed if feasible, and provides therapeutic recommendations based on CYP2C19 genotype.

Annotation

The EPAR also contains pharmacogenetic information related to the genotype of the HIV virus.

Excerpt from the atazanavir (Reyataz) EPAR:

Co-administration of voriconazole and REYATAZ/ritonavir is not recommended unless an assessment of the benefit/risk to the patient justifies the use of voriconazole (see section 4.4). At the time voriconazole treatment is required, a patient's CYP2C19 genotype should be performed if feasible. Therefore if the combination is unavoidable, the following recomendations are made according to the CYP2C19 status:

  • in patients with at least one functional CYP2C19 allele, close clinical monitoring for a loss of both voriconazole (clinical signs) and atazanavir (virologic response) efficacy is recommended.
  • in patients without a functional CYP2C19 allele, close clinical and laboratory monitoring of voriconazole-associated adverse events is recommended
    If genotyping is not feasible, full monitoring of safety and efficacy should be performed.

Description

Atazanavir (formerly known as BMS-232632) is an antiretroviral drug of the protease inhibitor (PI) class. Like other antiretrovirals, it is used to treat infection of human immunodeficiency virus (HIV). Atazanavir is distinguished from other PIs in that it can be given once-daily (rather than requiring multiple doses per day) and has lesser effects on the patient's lipid profile (the amounts of cholesterol and other fatty substances in the blood). Like other protease inhibitors, it is used only in combination with other HIV medications. The U.S. Food and Drug Administration (FDA) approved atazanavir on June 20, 2003. Wikipedia

Indication

Used in combination with other antiretroviral agents for the treatment of HIV-1 infection, as well as postexposure prophylaxis of HIV infection in individuals who have had occupational or nonoccupational exposure to potentially infectious body fluids of a person known to be infected with HIV when that exposure represents a substantial risk for HIV transmission.

Pharmacology, Interactions, and Contraindications

Mechanism of Action

Atazanavir selectively inhibits the virus-specific processing of viral Gag and Gag-Pol polyproteins in HIV-1 infected cells by binding to the active site of HIV-1 protease, thus preventing the formation of mature virions. Atazanavir is not active against HIV-2.

Source: Drug Bank

Pharmacology

Atazanavir (ATV) is an azapeptide HIV-1 protease inhibitor (PI) with activity against Human Immunodeficiency Virus Type 1 (HIV-1). HIV-1 protease is an enzyme required for the proteolytic cleavage of the viral polyprotein precursors into the individual functional proteins found in infectious HIV-1. Atazanavir binds to the protease active site and inhibits the activity of the enzyme. This inhibition prevents cleavage of the viral polyproteins resulting in the formation of immature non-infectious viral particles. Protease inhibitors are almost always used in combination with at least two other anti-HIV drugs. Atazanivir is pharmacologically related but structurally different from other protease inhibitors and other currently available antiretrovirals.

Food Interaction

Administration with food reduces pharmacokinetic variability.|Food increases product absorption.

Absorption, Distribution, Metabolism, Elimination & Toxicity

Biotransformation

Atazanavir is extensively metabolized in humans, primarily by the liver. The major biotransformation pathways of atazanavir in humans consisted of monooxygenation and dioxygenation. Other minor biotransformation pathways for atazanavir or its metabolites consisted of glucuronidation, N-dealkylation, hydrolysis, and oxygenation with dehydrogenation. In vitro studies using human liver microsomes suggested that atazanavir is metabolized by CYP3A.

Source: Drug Bank

Protein Binding

86% bound to human serum proteins (alpha-1-acid glycoprotein and albumin). Protein binding is independent of concentration.

Source: Drug Bank

Absorption

Atazanavir is rapidly absorbed with a T max of approximately 2.5 hours. Administration of atazanavir with food enhances bioavailability and reduces pharmacokinetic variability. Oral bioavailability is 60-68%.

Source: Drug Bank

Half-Life

Elimination half-life in adults (healthy and HIV infected) is approximately 7 hours (following a 400 mg daily dose with a light meal). Elimination half-life in hepatically impaired is 12.1 hours (following a single 400 mg dose).
