E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluate if the administration of a treatment consisting of dual long-acting HIV-specific broadly neutralizing antibodies (3BNC117-LS & 10-1074-LS (bNAbs)), in combination with an antiretroviral therapy (ART) in individuals with primary HIV-1 infection (PI) when compared to ART only (with neutralizing antibodies or placebo) will favour a period of HIV-1 remission when ART is interrupted 52 or 76 weeks later.
|
|
E.2.2 | Secondary objectives of the trial |
- Evaluate the tolerability of intravenous infusion of bNAbs;
- After bNAbs infusions and during ART, during analytic treatment interruption (ATI) and after ART resumption for non controller participants: o clinical, immunological and virological changes from baseline, o activation and inflammatory markers changes from baseline, o changes from baseline in the persistent viral reservoir,
- Baseline factors associated with plasma Viral Load control during ATI;
- To explore: expectations and motivations related to participation in the clinical trial and their evolution after having experienced such a participation, anticipation and understanding of risks and benefits related to participation, evolution over time of participation experience and of satisfaction with the information delivered, experience and perception of the ATI period, with an emphasis on its impact on prevention behaviours and sexual quality of life, reasons and experience related to refusal of participation. |
