About this study
Official title: Variation in Drug Interactions in People With HIV (PLWH) Aged 60 Years and Older on Stable Antiretroviral Therapy Making a Switch to Bictegravir/Tenofovir Alafenamide/Emtricitabine
Several cohort studies have recently shown a significant increase in the mean age of PLWH ( People Living With HIV) and in the prevalence of people in advanced age in the various cohorts, as a result of the marked increase in the mean life expectancy of these people achieved by modern antiretroviral combination therapies.
However, the high prevalence of comorbidities exposes PLWH in old age to the need to take multiple drug treatments in addition to antiretroviral therapy, with the gradually increasing risk of unfavorable pharmacokinetic interactions between antiretroviral drugs and drugs taken to treat the comorbidities.
This project consists of an observational, cohort, retrospective, single-center study and aims to evaluate the variation in the number and type of clinically significant drug interactions between antiretroviral therapy and concomitant therapies in PLWH aged >60 years on stable antiretroviral therapy who, for any reason at the Clinician's discretion, have made a switch from ongoing antiretroviral therapy to the bictegravir/emtricitabine/tenofovir alafenamide regimen.
Read the detailed description
The introduction of integrase inhibitors into clinical practice has greatly improved the efficacy and tolerability of modern antiretroviral combination therapies for the treatment of patients with HIV-1 infection. Indeed, these drugs have shown in registration studies high antiviral potency associated with a negligible incidence of short- and long-term adverse events, so much so that they are consistently included in the drug regimens recommended by all international guidelines for the treatment of HIV-positive patients naive to antiretroviral therapy.
Several cohort studies have recently shown a significant increase in the mean age of PLWH ( People Living With HIV) and in the prevalence of people in advanced age in the various cohorts, as a result of the marked increase in the mean life expectancy of these people achieved by modern antiretroviral combination therapies.
PLWH in advanced age, however, have a high prevalence of noninfectious comorbidities (cardiovascular disease, metabolic abnormalities, chronic renal failure, osteopenia-osteoporosis, neoplastic diseases, etc.), brought about by age-related aging but also by their accelerated biological aging caused by HIV infection and associated chronic inflammation and immunoactivation.
The high prevalence of comorbidities exposes PLWH in old age to the need to take multiple drug treatments in addition to antiretroviral therapy, with the gradually increasing risk of unfavorable pharmacokinetic interactions between antiretroviral drugs and drugs taken to treat the comorbidities.
The effect of such interactions can be either a reduction in plasma concentrations with reduced efficacy of antiretroviral drugs or an increase in plasma levels of concomitant drugs and the risk of toxicity induced by them.
The availability of integrase inbitors such as bictegravir, i.e., antiretroviral drugs characterized by a very low risk of drug interactions (because they are generally not metabolized by hepatic cytochrome P450 3A4 isoenzymes), has made it possible to significantly reduce the risk of interactions between antiretroviral therapy and concomitant therapy, especially in people of advanced age, while providing high viro-immunologic efficacy and a favorable effect on the cardio-metabolic profile.
This project consists of an observational, cohort, retrospective, single-center study and aims to evaluate the variation in the number and type of clinically significant drug interactions between antiretroviral therapy and concomitant therapies in PLWH aged >60 years on stable antiretroviral therapy who, for any reason at the Clinician's discretion, have made a switch from ongoing antiretroviral therapy to the bictegravir/emtricitabine/tenofovir alafenamide regimen.

However, the high prevalence of comorbidities exposes PLWH in old age to the need to take multiple drug treatments in addition to antiretroviral therapy, with the gradually increasing risk of unfavorable pharmacokinetic interactions between antiretroviral drugs and drugs taken to treat the comorbidities.

Questions about this trial
What is this clinical trial studying?
An observational study of HIV Infections and Drug Interaction, run by IRCCS Azienda Ospedaliero-Universitaria di Bologna 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 3 inclusion and 2 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: looking for participants now, as of the sponsor's last update on 5 Dec 2024. 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.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Leonardo Calza, Medicine (+390512143353, leonardo.calza@unibo.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Evaluation of the change in the total number of clinically significant drug-drug interactions (DDIs) (time frame: 12 Months). The study lists 2 primary outcomes in all. 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 NCT06717581, which also lists 5 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 5 Dec 2024.
