About this study
Official title: A Roll-Over Observational Study for the Extended Follow-Up of the Volunteers of the ISS T-003 Trial (ISS T-003 EF-UP2020)
A further extension of the follow-up of the volunteers of the ISS T-003 trial is being conducted in order to evaluate the persistence of vaccine immunogenicity as well as of the immunological and virological effects induced by the therapeutic immunization with Tat after about 10 years from vaccination.
Read the detailed description
The volunteers enrolled in the South African ISS T-003 trial (ClinicalTrials.gov NCT01513135; SANCTR: DOH-27-0211-3351) were recently enrolled in an observational study to extend the follow-up of the trial. The results of this study (ISS T-003 EF-UP, ClinicalTrials.gov NCT02712489; SANCTR: DOH-27-0615-4948) indicate the maintenance of anti-Tat Ab in a vast proposition of vaccinees.
The new roll-over observational study (ISS T-003 EF-UP2020; SANCTR: DOH-27-072022-7347) is to be conducted to further extend the follow-up of the participants of the ISS T-003 trial in order to evaluate the persistence of vaccine immunogenicity as well as of the immunological and virological effects induced by the therapeutic immunization with Tat after about 10 years from vaccination.
To this aim volunteers of the ISS T-003 study are included in a new 6-months study, with visits at weeks 0 and 24, during which the persistence and levels of anti-Tat antibodies (primary endpoint) and the CD4+ T-cell and HIV-1 plasma viraemia levels (secondary endpoint) will be evaluated. In addition, depending on the availability of residual specimens (PBMC, serum and plasma), further laboratory tests will be performed to investigate in-depth the immunological and virological profile of the volunteers. Clinical signs and symptoms of disease progression and AIDS-defining events will also be recorded.

Questions about this trial
What is this clinical trial studying?
An observational study of HIV Infections, run by Istituto Superiore di Sanità at 1 site in South Africa.
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 1 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 27 Mar 2026. 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 South Africa. 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?
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?
Anti-Tat humoral Immune responses (time frame: Week 0 and week 24). 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 NCT05680948, which also lists 22 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 27 Mar 2026.
