General information about the trial
|
|||
Main objective of the trial |
The aim of the study is to compare the virological efficacy of an intensive four-drug antiretroviral regimen against a standard regimen (chosen as the best one between an integrase-based or a protease inhibitor-based three drugs regimen) in HIV-1 subjects with Primary HIV Infection (PHI).
In addition, we wish to evaluate changes in immunological and safety laboratory parameters, in viral reservoirs and to determine drugs concentrations in plasma, cerebrospinal fluid, lymph nodes and GALT

Protection of trial subjects |
Approval by the local Ethics Committee was obtained before the beginning of the study and written informed consent was obtained from all patients at time of enrolment. Sponsor has stipulated an insurance to cover damages related to the study.

Recruitment details |
This Multicenter, parallel group, randomised, open label, study involved 78 patients (between 18 and 65 years) with PHI never treated among those attending the outpatient Clinic of Infectious Diseases, Ospedale San Raffaele and other Italian centres, involved in the INACTION network. Patients were enrolled between 2018 and 2020. | ||||||||||||||||||||

The primary end point is the change in total HIV-DNA level from baseline to 48 weeks.
HIV-DNA change form baseline to W48 is 0.912 in ARMA A, 0.267 in ARM B and 0.988 in ARM C.
No differences between Amrs.
