Overview

Elvitegravir is {{{aOrAn}}} {{{drugClass}}} that is FDA approved for the {{{indicationType}}} of {{{indication}}}. Common adverse reactions include {{{adverseReactions}}}.

Adult Indications and Dosage

FDA-Labeled Indications and Dosage (Adult)

There is limited information regarding Elvitegravir FDA-Labeled Indications and Dosage (Adult) in the drug label.

Off-Label Use and Dosage (Adult)

Guideline-Supported Use

There is limited information regarding Off-Label Guideline-Supported Use of Elvitegravir in adult patients.

Non–Guideline-Supported Use

There is limited information regarding Off-Label Non–Guideline-Supported Use of Elvitegravir in adult patients.

Pediatric Indications and Dosage

FDA-Labeled Indications and Dosage (Pediatric)

There is limited information regarding Elvitegravir FDA-Labeled Indications and Dosage (Pediatric) in the drug label.

Off-Label Use and Dosage (Pediatric)

Guideline-Supported Use

There is limited information regarding Off-Label Guideline-Supported Use of Elvitegravir in pediatric patients.

Non–Guideline-Supported Use

There is limited information regarding Off-Label Non–Guideline-Supported Use of Elvitegravir in pediatric patients.

Contraindications

There are no contraindications to VITEKTA. Due to the need to use VITEKTA with a protease inhibitor coadministered with ritonavir, prescribers should consult the complete prescribing information of the coadministered protease inhibitor and ritonavir for a description of contraindications.

Warnings

Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions

The concomitant use of VITEKTA and other drugs may result in known or potentially significant drug interactions, some of which may lead to:

  • Loss of therapeutic effect of VITEKTA and possible development of resistance
  • Possible clinically significant adverse reactions from greater exposures of concomitant drugs or elvitegravir.

See TABLE 4 for steps to prevent or manage these possible and known significant drug interactions, including dosing recommendations. Consider the potential for drug interactions prior to and during VITEKTA therapy; review concomitant medications during VITEKTA therapy; and monitor for the adverse reactions associated with the concomitant drugs.

Use with Other Antiretroviral Agents

  • Use of VITEKTA in combination with the fixed dose combination STRIBILD is not recommended, because elvitegravir is a component of STRIBILD.
  • VITEKTA is indicated for use in combination with a protease inhibitor coadministered with ritonavir and with other antiretroviral drug(s). VITEKTA in combination with a protease inhibitor and cobicistat is not recommended because dosing recommendations for such combinations have not been established and may result in suboptimal plasma concentrations of VITEKTA and/or the protease inhibitor, leading to loss of therapeutic effect and development of resistance.

Immune Reconstitution Syndrome

Adverse Reactions

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety assessment of VITEKTA is primarily based on data from a controlled clinical trial, Study 145, in which 712 HIV-1 infected, antiretroviral treatment-experienced adults received VITEKTA (N=354) or raltegravir (N=358), each administered with a background regimen consisting of a fully active protease inhibitor coadministered with ritonavir and with other antiretroviral drug(s) for at least 96 weeks.

The proportion of subjects who discontinued study treatment due to adverse events, regardless of severity, was 3% in the VITEKTA group and 4% in the raltegravir group. The most common adverse reaction (all Grades, incidence greater than or equal to 5%) in subjects receiving VITEKTA in Study 145 was diarrhea. See also TABLE 2 for the frequency of adverse reactions occurring in at least 2% of subjects in any treatment group in Study 145.

Less Common Adverse Reactions Observed in Treatment-Experienced Studies: The following adverse reactions occurred in <2% of subjects receiving VITEKTA combined with a protease inhibitor and ritonavir. These reactions have been included because of their seriousness, increased frequency on VITEKTA compared with raltegravir, or investigator's assessment of potential causal relationship.

Gastrointestinal Disorders: abdominal pain, dyspepsia, vomiting General Disorders and Administration Site Conditions: fatigue Psychiatric Disorders: depression, insomnia, suicidal ideation and suicide attempt (<1%, most in subjects with a pre-existing history of depression or psychiatric illness) Skin and Subcutaneous Tissue Disorders: rash Laboratory Abnormalities: The frequency of laboratory abnormalities (Grades 3–4), occurring in at least 2% of subjects in either treatment group in Study 145, is presented in Table 3.

Postmarketing Experience

Drug Interactions

Effect of Concomitant Drugs on the Pharmacokinetics of Elvitegravir

Elvitegravir is metabolized by CYP3A. Drugs that induce CYP3A activity are expected to increase the clearance of elvitegravir, as well as ritonavir. This may result in decreased plasma concentrations of elvitegravir and/or a concomitantly administered protease inhibitor and lead to loss of therapeutic effect and to possible resistance.

Established and Other Potentially Significant Interactions

Table 4 provides dosing recommendations as a result of potentially clinically significant drug interactions with VITEKTA. These recommendations are based on either drug-drug interaction studies or predicted interactions due to the expected magnitude of interaction and potential for serious adverse events or loss of therapeutic effect.

For additional drug-drug interactions related to protease inhibitors coadministered with ritonavir, consult the prescribing information of the coadministered protease inhibitor and ritonavir.

Elvitegravir (EVG) is an investigational drug for the treatment of HIV. It acts as an integrase inhibitor. It is undergoing clinical trials conducted by the pharmaceutical company Japan Tobacco.[1][2]

According to the results of the phase II clinical trial, patients taking once-daily elvitegravir boosted by ritonavir had greater reductions in viral load after 24 weeks compared to individuals randomized to receive a ritonavir-boosted protease inhibitor.[3]
