Efficacy, Safety & Tolerability of Switching EFV/TDF/FTC to BIC/FTC/TAF in Virologically Suppressed Adults With HIV-1

September 13, 2024 updated by: Midland Research Group, Inc.

"Efficacy, Safety, and Tolerability of Switching EFV/TDF/FTC to BIC/FTC/TAF in Virologically Suppressed Adults With HIV-1 Infection."

This study evaluates the efficacy, safety and tolerability of switching from the older, established single tablet regimen of ATRIPLA® (EFV/FTC/TDF) to a new single tablet regimen of BIKTARVY® (BIC/FTC/TAF), in HIV-1 infected adult subjects who are virologically suppressed (HIV-1 RNA<50 copies/mL).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Therapeutic dosage of the tenofovir disoproxil fumarate (TDF) component of ATRIPLA® requires plasma concentrations of the drug that are associated with nephrotoxicity and decreased bone mineral density. Tenofovir alafenamide fumarate (TAF) has a unique metabolism that results in higher intracellular levels of the active phosphorylated moiety tenofovir-diphosphate. Compared with TDF, the therapeutic dosage of TAF reduces tenofovir plasma concentrations by over 90%. This reduction in plasma concentration results in decreased renal and bone risks. TAF has the potential to improve on the efficacy and safety profile of TDF.

Efavirenz, another component of ATRIPLA® is widely associated with neuropsychiatric side-effects, including sleep disturbances, depression, and anxiety. Switching from Efavirenz to an integrase inhibitor is associated with improvements in mood.

Bictegravir (BIC) is a novel, once daily integrase inhibitor. It has been shown to have potent antiviral activity, a favorable pharmacokinetic profile, good tolerability and an improved resistance profile when compared to previous integrase inhibitors. In a phase 2 trial investigating previously untreated people with HIV, bictegravir plus emtricitabine and tenofovir alafenamide (BIKTARVY®) vs dolutegravir, plus emtricitabine and tenofovir alafenamide both showed high efficacy up to 24 weeks and both regimens were well tolerated.

Additionally, switching HAART experienced patients to BIKTARVY® has been shown to be non-inferior to continuation of regimens containing Atazanavir or Darunavir, when they were given with either lamivudine/abacavir or FTC/TDF.

The Investigators plan to evaluate in a real world setting the efficacy, safety and tolerability of switching from the older, established single tablet regimen of ATRIPLA® (EFV/FTC/TDF) to a new single tablet regimen of BIKTARVY® (BIC/FTC/TAF).

Within the limitations of a real-world study, Investigators have attempted to replicate the protocol of Gilead Science's Phase 3 study evaluating a switch to BIC/FTC/TAF from dolutegravir plus either FTC/TAF or FTC/TDF14. This will have the potential benefit of comparing different regimen switches as well as potentially adding robustness to the body of data regarding BIC/FTC/TAF.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
