About this study

Official title: A Phase IIIB/IV Randomised Open-label Trial Comparing Dolutegravir With Pharmaco-enhanced Darunavir Versus Dolutegravir With Predetermined Nucleosides Versus Recommended Standard of Care ART Regimens in Patients With HIV-1 Infection Failing First Line Therapy.

D²EFT is a randomised, open-label study in HIV-1 infected patients failing first-line antiretroviral therapy (ART). The study compares 2 regimens of second-line ART (dolutegravir and darunavir pharmaco-enhanced with ritonavir and dolutegravir and 2 prespecified NRTIs) with the WHO recommended regimen of 2NRTIs plus a ritonavir-boosted PI (Standard of Care (SOC)). 1,010 participants from 14 predominantly low-middle income countries will be followed for 96 weeks with the primary endpoint at week 48. The design is based on the hypothesis that one or both of the new regimens will be non-inferior to SOC in terms of virologic control while being easier to take, economically viable and affording simplification of treatment programs.

Read the detailed description

Consenting participants will be screened and within 45 days randomly allocated to receive either dolutegravir and darunavir/ritonavir, dolutegravir and 2 prespecified NRTIs or the SOC regimen. Participants will be seen four weeks after their randomisation (week 0) visit and then at weeks 12, 24, 48 and 96. Consenting participants will have storage samples collected and cryopreserved at their week 0, 48 \& 96 visits. This repository will be used in future for central baseline resistance testing, pharmacogenomic testing (separate consent required) and has inherent value for later studies of HIV pathogenesis. A 1-time PK sample will be collected at week four for future testing and any participants failing therapy at 24 weeks will have a plasma sample stored for future genotypic resistance testing.

A number of secondary outcomes will be considered in order to compare the performance of the two study treatment regimens. Secondary analyses will focus on virological, immunological, safety, antiretroviral treatment change and medication adherence. A comparison of costs and estimates of cost-effectiveness for the randomised comparison will be a critical component of this study. ART costs will be assessed across study arms. Health-care utilisation will be self-reported and then used to estimate costs. Safety data, viral loads and quality of life data will also be analysed.

The open label nature of the study allows routine care to be undertaken and the use of objective endpoints limit potential bias. The study has well defined and integrated clinical data collection and patient management systems that have been shown to be effective in a wide range of clinical settings.

The choice of NRTIs in the SoC regimen is based on clinical judgement and may be guided by resistance testing if locally available, while those used with dolutegravir are predetermined (tenofovir and lamivudine or emtricitabine). The NRTIs are not provided via the study. At the end of 96 weeks (completion of the protocol) study drug can be offered to all participants for a further 48 weeks as informed by the 48-week study results and clinical judgement. After 144 weeks study drug will no longer be available and composition of the participant's post-study regimen will be the clinician's decision.'

Model description
A third arm has been incorporated using a multi-arm, multi-stage (MAMS) design. This design allows for the 2-arm study (DTG+DRV/r vs DRV/r+2NRTI) to continue accrual while preparation of the new arm (DTG+2NRTI) is begun in parallel. Once that arm is ready, accrual to it begins and the study switches to the second stage. All participants accrued to Arm 1 and 2 throughout the trial are contemporaneous and can be compared, while the subjects accrued to Arm 3 are compared only to their contemporaries in Arms 1 and 2. The size of Arm 3 is sufficient to allow adequate power comparisons, and stage effects are minimized while non-contemporaneous control data are not required.

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 5 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 18 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 28 sites in Argentina, Indonesia, Thailand, Mexico, South Africa and 9 more countries. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Results are not available in the source record.

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?

The proportion of participants in each arm whose plasma viral load is <50 copies/mL at 48 weeks by intention to treat. (time frame: At 48 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03017872, which also lists 3 linked publications.

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 18 Apr 2023.
