About this study
Official title: Multi-center Study to Evaluate Virological Efficacy, Safety Tolerability, Drug Exposure and Patients' Reported Outcomes Over 48 Weeks Following Randomization to 2-drug Therapy With DTG/3TC FDC or Continuing Current Antiretroviral Tenofovir (TAF or TDF)-Containing Regimen (T-CR) in HIV-1 Infected Virologically Suppressed
Strategies for optimizing antiretroviral treatment in virologically suppressed patients are still a major challenge in the field of HIV. These strategies include improving the toxicity and tolerability of drugs in the short and long term, such as replacing toxic agents with safer ones or reducing the number of drugs in the combination. Tenofovir alafenamide (TAF) is a novel prodrug of tenofovir (TFV) that is converted intracellularly to the active form, resulting in higher concentrations of TFV diphosphate in circulating lymphocytes than those obtained with tenofovir disoproxil fumarate (TDF). Because of these pharmacokinetic properties, TAF results in 91% lower plasma exposure to TFV. Phase 3 studies have established the virological noninferiority of TAF to TDF, with a lower frequency of renal and bone adverse events. Replacing TDF with TAF may be a safe and effective option to reduce toxicities when switching from one ARV strategy to another and, to date, could represent the optimization of a three-drug regimen. Dolutegravir (DTG) is a potent INSTI that exhibits rapid and potent viral load reduction and a high barrier to resistance.

What is being measured
The primary outcome is the main question the study is designed to answer.
HIV-RNA < 50 copies/ml
Proportion of patients maintaining a HIV-RNA < 50 copies/ml according to FDA snapshot algorithm at 48 weeks according to an ITT NC = failure approach in which all randomized patients will be included and considered failures independently of the reason they did not complete the follow-up.
Measured: 96 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Antiviral Agents in people with HIV Infections, run by Fondazione Policlinico Universitario Agostino Gemelli IRCCS at 1 site in Italy.
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 8 inclusion and 3 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 13 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Italy. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
HIV-RNA < 50 copies/ml (time frame: 96 weeks). 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 13 Sep 2023.
