Observational Study for the Extended Follow-up of the Patients Enrolled in the Therapeutic Clinical Trial ISS T-002
An observational study of HIV Infection, run by Barbara Ensoli, MD, PhD at 8 sites in Italy.
Trial summary
An observational study to prospectively follow-up the patients enrolled in the ISS T-002 clinical trial up to 132 weeks. The primary endpoint of this study is to evaluate the persistence, in term of frequency, magnitude and quality, of the anti-Tat humoral and cellular immune response in the HIV-1 infected individuals… Read more about this study

What is being measured
The primary outcome is the main question the study is designed to answer.
anti-Tat humoral immune response
The primary endpoint of the study is to evaluate the persistence, in term of frequency, magnitude, and quality of the anti-Tat humoral immune response in HAART-treated patients previously immunize with Tat in the ISS T-002 phase II clinical trial.
Measured: Every 3 months, up to 2.5 years
Secondary outcomes (2)
Testing of the additional Immunological parameters detailed below as a second line testing
The secondary endpoint of the study is to identify and validate immunological testing for future efficacy vaccine clinical trials, as follows: Lymphoproliferative response to Tat, anti-Tat γIFN, IL4 and IL2 production; In vitro neutralization of Tat activity (Tat/Env uptake); Lymphocyte subsets; Anti-Tat IgG subclasses; Epitope mapping of anti-Tat IgM and IgG; Anti-HIV regulatory and structural proteins antibodies; ADCC; Neutralization of Tat activity by rescue assay; Neutralization of primary HIV isolates; Anti-CCR5 and Anti-CD4 antibodies; Lymphoproliferative response to Env, mitogens and recall antigens In vitro γIFN, IL4 and IL2 production in response to Tat (ICS) and to Env (ICS/Elispot); B cells phenotype; Characterization of Treg cells; PBMC ICS for granzyme, perforin, cytokines and chemokines; Th1 and Th2 cytokines and chemokines; Lymphocytes spontaneous cell death; B cell cloning; Characterization of clono-specific antibodies; Serum/plasma determination of sCD4.
Measured: Every 3 months, up to 2.5 years
Testing of virological parameters detailed below, as a second line testing
The secondary endpoint of the study is to identify and validate virological testing for future efficacy vaccine clinical trials, as follows: HIV-1 plasma viremia (viral RNA copies), HIV-1 sequencing and virus phylogenetic analysis, Genotypic resistance, Viral tropism, Anti-HBV antibodies, HBV antigens (HbsAg, HbeAg), Anti-HCV antibodies and plasma viremia, HHV-8 antibodies and plasma viremia, HIV-1 Proviral DNA copies.
Measured: Every 3 months, up to 2.5 years

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
An observational study to prospectively follow-up the patients enrolled in the ISS T-002 clinical trial up to 132 weeks. The primary endpoint of this study is to evaluate the persistence, in term of frequency, magnitude and quality, of the anti-Tat humoral and cellular immune response in the HIV-1 infected individuals who participated to the ISS T-002 and who have received at least 3 immunizations. The secondary endpoint is to define and validate novel laboratory tests for future efficacy clinical trials.
