About this study

Official title: Prospective, Therapeutic Drug Monitoring Study of Reduced-Dose Efavirenz (400 mg) Plus Tenofovir Disoproxil Fumarate (TDF) and Lamivudine in a Fixed-Dose Combination Tablet (Combo) for Patients Receiving Co-Formulated TDF, Emtricitabine and Efavirenz (Atripla) With Viral Suppression in Taiwan

Prospective, Therapeutic Drug Monitoring Study of Reduced-Dose Efavirenz (400 mg) Plus Tenofovir Disoproxil Fumarate (TDF) and Lamivudine in a Fixed-Dose Combination Tablet (Combo) for Patients Receiving Co-Formulated TDF, Emtricitabine and Efavirenz (Atripla) with Viral Suppression in Taiwan

Read the detailed description

Efavirenz (EFV) is the most widely used non-nucleoside reverse transcriptase inhibitor (NNRTI). The recommended dose of EFV is 600 mg daily; however, a phase II study showed no significant difference in viral suppression rates across the different EFV groups (200 mg, 400 mg, and 600 mg) at 24 weeks. The week 96 analysis of ENCORE 1 study confirmed the durable virological non-inferiority of EFV 400 mg to the standard 600 mg dose when given as initial therapy with tenofovir disoproxil fumarate (TDF) and emtricitabine (FTC). Fewer EFV-related adverse events (AEs) and fewer treatment discontinuations were also observed in the reduced dose group. The efficacy and safety findings provide robust evidence to redefine the EFV dose for HIV treatment.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 3-in-1 tablet (EFV 400mg, TDF 300mg, 3TC 300mg)Drug

    Also called non applicable

    All eligible subjects will receive 3-in-1 tablet (EFV 400mg, TDF 300mg, 3TC 300mg) once daily for 24 weeks orally on empty stomach before bedtime. If the event of toxicity or tolerability issues requires a change from study drug, switching to the best available treatment will be recommended.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing 3-in-1 tablet (EFV 400mg, TDF 300mg, 3TC 300mg) in people with HIV Infections, run by Yu-Jay Corp. at 2 sites in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 7 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

C12 EFV concentration (time frame: Week 4). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Feb 2020.
